Description

Description: TECHNICAL FIELD The present invention relates to a dishwasher for washing dishes.

2. Description of the Related Art Conventionally, this type of dishwasher has a configuration as shown in FIG.

That is, the washing tank 2 is provided inside the main body 1, and water or hot water is supplied into the washing tank 2 by the water supply valve 3.
The washing water stored in the washing tank 2 is attached to a pump chamber communicating with the other side of the drain hole 4 and circulates inside the washing tank 2 by a washing pump 6 driven by a motor 5. . That is, in this circulation, the washing water is sucked into the washing pump 6 from the drain hole 4 and is supplied from the washing pump 6 to the washing nozzle 7 at the bottom of the washing tank 2 and is jetted from there to wash the dishes. Drain hole 4 again
It is done along the route of entering. Cleaning nozzle 7 and cleaning tank 2
A heater 8 for heating the washing water is provided between the bottom and the bottom. In addition, tableware can be arranged in an orderly manner above the cleaning nozzle 7, and the tableware basket 9 designed to effectively spray the cleaning water onto the tableware can be pulled out to the front outside of the main body 1 by having wheels or rollers. It is installed in a state
A door 10 that can be opened and closed is attached to the front part of the washing tank 2.

Here, in order to clean the tableware neatly, the chemical power of the detergent is required together with the injection of the cleaning water by the cleaning nozzle 7.

In a dishwasher without a pre-washing step before the main washing step, the detergent is placed above the open door 10 or directly into the washing tank 2. In a dishwasher having a preliminary washing step, a door 10 is provided with a detergent introduction device 11 for introducing a detergent into the washing tank 2 in an optional step during the washing step. The detergent charging device 10 prevents the detergent from falling into the cleaning tank 2 when the door 10 is closed and the main body for storing the detergent, and also prevents the detergent from flowing out by jetting of the cleaning water except in any process. It has a lid, a racket mechanism for locking the lid, and a driving device such as a solenoid for releasing the lid in an optional step.

However, in such a conventional configuration, in a dishwasher without the detergent input device 11, the detergent falls into the washing tank 2 when the door 10 is closed. If a small amount of washing water remains at the bottom, a part of the detergent is discharged in the drainage process at the beginning of the process, and the detergency in the main washing process is reduced. In addition, if the operation is not performed immediately after the detergent is added in preparation for cleaning, the detergent hardens at the bottom of the cleaning tank 2 and cannot be sufficiently melted in the cleaning process, and sufficient cleaning cannot be performed. Furthermore, in the dishwasher only for hot water supply, when hot water is supplied,
Since water remaining in the piping comes out, it is necessary to discharge this water before the washing step, but at that time, there is a problem that the detergent flows out.

Next, when looking at a dishwasher having a detergent dispensing device 11, the detergent dispensing device 11 is disposed on the door 10 in order to make it easy for a user to put detergent. However, the detergent insertion device 11
As described above, an electric component such as a solenoid is required as a driving device as described above. Therefore, in order to dispose the driving device inside the humid door 10, it is necessary to give sufficient consideration to humidity.
Further, there is a problem that a lead wire needs to be passed through the opening and closing portion of the door 10 to supply electricity to the inside of the door 10 that opens and closes, so that there is a need for disconnection due to the bending.

SUMMARY OF THE INVENTION In view of the above problems, it is a first object of the present invention to prevent a detergent from flowing out in a drain process before a washing process with a simple configuration.

Means for Solving the Problems In order to achieve the first object, the present invention provides a dish basket provided with an inclined dish-like detergent container.

Action Since the detergent container of the present invention is arranged in the tableware basket, the user can put the detergent in a state where the tableware basket is pulled out, so that the detergent container is very easy to fill. Also, unlike on the door, the portion containing the detergent does not rotate, so that the detergent does not fall on the bottom of the washing tank, and does not harden or flow out at the first drainage. Then, in the main cleaning step, the detergent flows by the cleaning water jetted from the cleaning nozzle, and the detergent is correctly used in the main cleaning step, thereby ensuring the cleaning power.

Embodiment An embodiment of the present invention will be described below with reference to the accompanying drawings. The basic configuration of the dishwasher of the present invention is the same as the configuration shown in FIG. 4, and the same parts are denoted by the same reference numerals.
Description is omitted.

FIG. 1 shows a main part of a tableware basket provided with a detergent container, which is a feature of the present invention. In FIG. 1, 9 is a tableware basket main body, and 12 is a dish-shaped detergent container according to the present invention. The detergent container 12 is attached to the tableware basket 9 with claws 12a. The bottom 12b of the detergent container 12 is dish-shaped, and the detergent is put therein. Even if the tableware basket 9 is put in the washing tank 2, the detergent remains in the bottom 12 b of the detergent tank and does not drop to the bottom of the washing tank 2.
Therefore, it does not flow out of the machine at the time of the first drainage. In addition, since the bottom portion 12b of the detergent container is provided with an inclination, the detergent is washed away by the washing water jetted from the washing nozzle 7 during the main washing step, and is dissolved in the washing water to contribute to washing. Therefore, all the detergents put in by the user are used in the main cleaning step, and the cleaning performance is secured. further,
This inclination of the bottom 12b leaves no wash water after the final drainage. In order to further ensure the operation, a cutout 12c is provided in a part of the lower side wall.

The above-described structure is an embodiment of the detergent container used for the model without the pre-washing step. Next, referring to FIGS. 2 and 3, the automatic detergent supply line used for the model with the pre-washing step will be described. An example will be described.

The dish basket 9 has a dish-shaped detergent container body 13 for storing detergent, a cover 14 for covering the upper portion thereof, a spring 15 for generating a force for releasing the cover 14, and a claw for locking the cover 14 when the cover 14 is closed. The latch mechanism 16 is arranged. The detergent container 13 is attached to the tableware basket 9 with claws, and the portion for storing the detergent is constituted by an inclined dish-shaped portion, as in the above-described embodiment. However, compared to the above-described embodiment, since the detergent is provided, the detergent does not drop due to the vibration during the movement of the dish basket 9, so that the inclination angle can be increased.
This is very advantageous for the speed at which the detergent flows out and how the washing water remains after draining. Next, the detergent container
A cover 14 is provided which engages with the cover 13 and covers the portion for containing the detergent. A coil spring 15 is provided on a pivot portion of the lid 14 so as to apply a force in a direction in which the lid 14 is opened, and is always opened when not locked by the latch mechanism 16. Then, when the user closes the lid 14, the claws of the latch mechanism 16
And the lid 14 is closed. In this closed state, the washing water injected by the washing nozzle 7
The detergent does not flow into the detergent container main body 13 containing the detergent, and the detergent does not flow out. However, if it is necessary to further ensure this effect, the engaging portion between the detergent container main body 13 and the lid 14 is sealed by rubber packing or the like.

Next, a solenoid 17 which is a drive mechanism for releasing the latch mechanism 16 is disposed outside the cleaning tank 2. Solenoid 17
When power is supplied to the solenoid 17, the tip of the plunger (latch mechanism releasing operation section) 17 a of the solenoid 17 projects into the cleaning tank 2. A packing 18 for preventing leakage of cleaning water from the cleaning tank 2 and a solenoid are provided at the tip of the plunger 17a.
A spring 19 is also provided that operates so that the tip of the plunger 17a is retracted when the power is not supplied to the 17.

The operation according to these configurations will be described. The user puts the detergent into the detergent container main body 13 attached to the dish basket 10 and closes the lid 14. At this time, the lid 14 is kept closed by the claws of the latch mechanism 16 as described above. When the tableware basket 9 on which tableware is set is stored in the washing tank 2, the latch mechanism 16 and the optical end of the plunger 17a come to a position where they are engaged. At this time, the light end of the plunger 17a is recessed. Thus, lid 14 remains closed. In the drainage and preliminary washing steps up to the main washing step, the lid 14 of the detergent container remains in this state. In the main cleaning step, when the solenoid 17 is energized, the plunger 17a of the solenoid 17 is sucked, and the tip of the plunger 17a protrudes toward the inside of the cleaning tank 2. At this time, the tip of the plunger 17a pushes the rod of the latch mechanism 16 to release the claw that has locked the lid 14.
Therefore, the lid 14 is opened by the force of the spring 15 of the shaft support. Then, the detergent inside flows out by the washing water injected from the washing nozzle 7 and dissolves in the washing water.

In the above example, the embodiment in which the linear motion is directly used by the suction of the solenoid 17 has been described.
Bimetal or the like due to self-heating can be used, and in the latch mechanism, a configuration utilizing rotational movement can be considered. In the present invention, the detergent container body 13 and the lid 14 are used.
Are arranged in a tableware basket 9 inside the washing tank 2, and driving components for electric components are arranged outside the washing tank 2.

Effects of the Invention As described above, according to the present invention, in a dishwasher without a pre-washing step, a dish-shaped detergent container having an inclination is arranged in a dish basket, so that the state of residual water is any case. No spillage of detergent in the first drainage. In addition, the degree of hardening of the detergent when the detergent is left in the washing tank is far less. Therefore, the detergent is reliably used in the main cleaning step, so that the cleaning performance can be ensured.
