DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a dishwasher for washing dishes with washing water circulated by a pump in a washing tank supported on an outer frame movably in the front-rear direction.

[0002]

2. Description of the Related Art In recent years, a dishwasher for washing dishes by circulating washing water by a pump through a washing nozzle in a washing tank has become mainstream.

Conventionally, this type of dishwasher has been configured as shown in FIG. Hereinafter, the configuration will be described.

As shown in FIG. 1, a washing tank 1 is supported by an outer frame 2 so as to be movable in the front-rear direction. In the washing tank 1, a washing nozzle 3 for spraying washing water is rotatably provided. , A tableware basket 5 for storing tableware 4 is arranged. While the washing water in the washing tank 1 is being warmed by the heater 6, the washing water is sucked from the drain port 8 by the first pump body 7 joined to the bottom of the washing tank 1 and sent to the washing nozzle 3. The washing water sent to the washing nozzle 3 is jetted into the washing tank 1 to wash the dishes 4 stored in the dish basket 5. When the cleaning is completed, the cleaning water is sucked from the drain port 8 by the second pump body 9 joined to the bottom of the cleaning tank 1 and discharged from the drain path 10 to the outside of the machine.

[0005]

In such a conventional dishwasher, since a space for disposing the first pump body 7 and the second pump body 9 is required below the washing tank 1, drainage is required. The bottom surface of the washing tank 1 including the mouth 8 is located at a relatively high position in the dishwasher body. For this reason, the water outlet 8 and the water surface at the time of washing become closer, and air is entrained together with the washing water, so that the efficiency of the first pump body 7 decreases, and the jet pressure of the washing water from the washing nozzle 3 decreases, The cleaning performance deteriorates. In order to prevent this, it is necessary to raise the water level at the time of cleaning, but this leads to an increase in the amount of water used.

When the water level at the start of driving of the second pump body 9 and the drain port 8 are close to each other, air is entrained together with the washing water, so that the efficiency of the second pump body 9 decreases,
This leads to reduced drainage capacity and noise. If the water level at the start of driving the pump is raised to prevent this, the amount of residual water in the dishwasher main body after the drainage ends increases.

Further, when the water level is raised, it is necessary to increase the positions of the washing nozzle 3 and the dish basket 5, so that a dish with a large diameter or a tall cup cannot be stored, which leads to a reduction in the dish capacity.

When the cleaning tank 1 is moved quickly in the front-rear direction, the first pump body 7 and the second pump
The inertial force of the pump body 9 acts on the joint of the cleaning tank 1, and the joint may be deformed or damaged.

The present invention has been made to solve the above-mentioned problems, and the position of the bottom of a cleaning tank including a drainage port is lowered to secure cleaning performance and drainage performance, and to prevent generation of noise.
An object of the present invention is to provide a dishwasher having a large water volume with a low water level and a small amount of water.

[0010]

SUMMARY OF THE INVENTION The present invention, in order to achieve the above object, and configured to circulate the wash water by pump body into the cleaning tank which is movable in the longitudinal direction in the outer frame,
Fixed pump body this to the back outside of the cleaning tank, the pump
The axial direction of the fixed shaft for fixing the body is the moving direction of the washing tank.
They are the same.

[0011] Thus, regardless of the size of the pump body, the position of the bottom surface of the cleaning tank 1 comprising a drain port 8 can be relatively low things, without increasing the degradation and residual water content of the wash performance It is possible to provide a dishwasher having a low water level, a small amount of water and a large dish capacity.

[0012]

An embodiment of the present invention will be described below with reference to the drawings. The same components as those in the conventional example are denoted by the same reference numerals, and description thereof is omitted.

As shown in FIG. 1, the cleaning tank 11 is
The washing tank 1 is supported so as to be movable in the front-rear direction.
A washing nozzle 3 for injecting washing water is rotatably provided in 1, and a tableware basket 5 for accommodating tableware 4 is arranged.

The first pump body 12 is driven by a drive motor 13, sucks washing water into the washing tank 11 from the drain port 8, sends the washing water to the washing nozzle 3, and jets the washing water into the washing tank 11 from the washing nozzle 3. The cleaning water is circulated in the cleaning tank 11. The second pump body 14, like the first pump body 12, is driven by the drive motor 13 to draw the cleaning water in the cleaning tank 11 from the drain port 8 and discharge it from the drain path 10 to the outside of the machine. Here, by operating the second pump body 14,
When the washing water in the washing tank 11 is discharged to the outside of the machine, the rotation direction of the drive motor 13 is rotated in a direction opposite to the direction in which the first pump body 12 is operated.

The first pump body 12, the second pump body 14, and the drive motor 13 are integrally formed, and are suspended outside the back of the washing tank 11. Here, a recess 15 and a fixed shaft 16 are integrally formed outside the back surface of the cleaning tank 11 as shown in FIG. 2, and the first pump body 12 and the second pump body 1 are formed.
4. A pump body 17 integrally formed with a drive motor 13 is joined with a screw 19 via a buffer member 18.

The operation of the above construction will be described. The user pulls out the washing tank 11 from the outer frame 2 and moves the tableware 4 away.
In and out. After the tableware 4 is stored in the washing tank 11 and the detergent is added, when the operation is started, the operation of the heater 6, the drive motor 13 and the like is controlled by the control device (not shown), and the washing in the washing tank 11 is performed. While the water is being heated by the heater 6, the water is sucked from the drain port 8 by the first pump body 12 and sent to the washing nozzle 3. The washing water sent to the washing nozzle 3 is jetted into the washing tank 11 to wash the dishes 4 stored in the dish basket 5. When the cleaning is completed, the rotation direction of the drive motor 13 is reversed, and the cleaning water is sucked from the drain port 8 by the second pump body 14 and discharged from the drain path 10 to the outside of the machine.

Here, the pump body 1 in which the first pump body 12, the second pump body 14, and the drive motor 13 are integrally formed
7 is suspended outside the back surface of the cleaning tank 11, so that a simplified pump body 17 is provided on the fixed shaft 1 provided in the cleaning tank 11.
6, the dishwasher can be provided in a simple and inexpensive configuration.

Also, regardless of the size of the pump body 17,
Since the position of the bottom surface of the washing tank 11 including the drain port 8 can be made relatively low in the dishwasher main body, even when the water level at the time of washing and draining is lowered, the pump body 17 does not entrap air. In addition, a dishwasher having a low water level, a small amount of water, and a large dish capacity can be provided because the washing performance is not deteriorated, the remaining water amount is increased, and noise is not generated.

Further, the pump body 17 is suspended outside the back surface of the cleaning tank 11 via the buffer member 18 so that the inertia force of the pump body 17 acting on the joint of the pump body 17 when the cleaning tank 11 is moved back and forth. Can be absorbed by the cushioning member 18, and deformation and breakage of the joint can be prevented.

In this embodiment, the first pump body 1
2, the second pump body 14 and the drive motor 13 are integrally formed and are suspended outside the back surface of the cleaning tank 11, but the first pump body 12 and the second pump body 14 are separately driven. The first pump body 1 is configured to be driven by a motor.
Even if at least one of the second and second pump bodies 14 is suspended outside the back surface of the cleaning tank 11, the same operation and effect can be obtained.
