Description

Detailed Description of the Invention

[0001]

TECHNICAL FIELD The present invention relates to a dishwasher. More specifically, the present invention relates to a dishwasher with an improved sealing mechanism for the drainage path of washing water.

[0002]

2. Description of the Related Art A dishwasher arranges dishes stored in a dish basket in a washing tank, puts a predetermined amount of detergent into the washing tank, and supplies washing water to wash the dishes. ,
After that, the steps such as rinsing and drying are performed to wash dirty dishes. However, in reality, not all of the above steps are performed, and for example, in a small household,
It is often used to perform only the drying process.

By the way, in the drainage path of the washing water,
It is common practice to store a certain amount of cleaning water in a cleaning water storage portion formed at the bottom of a cleaning tank to seal the water and provide a trap function. By doing so, the odor from the outside is prevented from entering the cleaning tank, or the odor of the cleaning tank is not leaked to the outside. However, if only the drying step is often performed as described above, there is no replenishment of the washing water, so that there is a problem in that the sealing water is decomposed and unsanitary, and an offensive odor is generated. further,
Since the water evaporates, there is no sealing water, and the above trap function cannot be fulfilled.

[0004]

In order to solve the above problems, it is necessary to perform a cleaning operation or change the sealing water on a regular basis, but it is troublesome and troublesome to use. The person does not necessarily enforce these tasks, and the measures have been required. The present invention was devised under such circumstances, and eliminates the spoilage of the sealing water in the cleaning water storage portion formed at the bottom of the cleaning tank even when the drying step is often used. It is an object of the present invention to provide a dishwasher that always has a trap function without causing the sealing water to run out.

[0005]

In order to solve the above problems, the inventions described in claims 1 to 5 take the following technical means. That is, a washing operation including a washing step for washing the dishes stored in the dish basket and a rinsing step for rinsing the dishes after washing, and a washing tank for performing a drying operation are included, and washing water from the washing step and the rinsing step. In a dishwasher in which a fixed amount of water is stored as sealing water in the cleaning water storage portion formed at the bottom of the cleaning tank, and the fixed amount of cleaning water is sequentially discharged, the cleaning water storage portion is A dishwasher is provided which is provided with a water supply means capable of arbitrarily supplying water.

According to the second aspect of the present invention, the means for supplying water to the cleaning water storage section may supply water and discharge water at predetermined intervals regardless of whether or not the cleaning operation is performed. . Further, as in the invention described in claim 3, after the cleaning operation is performed, water may be supplied to the cleaning water storage unit and drained at predetermined time intervals. Further, as in the invention described in claim 4, it is preferable that after the water is supplied from the water supply means to the cleaning water storage portion, the fan is operated to ventilate the cleaning tank. By doing so, it is possible to prevent dew condensation on the dried tableware. Further, as in the invention according to claim 5, it is preferable that the water injection from the water supply means to the flush water storage portion flows downward. Further, it is preferable to provide a guide cover that guides downward so as not to scatter to the surroundings and wet the dried dishes.

[0007]

BEST MODE FOR CARRYING OUT THE INVENTION Preferred embodiments of the dishwasher of the present invention according to claims 1 to 5 will be described below in more detail with reference to the drawings. FIG. 1 is a side sectional view of the dishwasher. In FIG. 1, a cleaning tank 1
Is equipped with a wash water storage portion 11 in which a fixed amount of wash water is stored, and the lower portion of the wash water storage portion 11 is U
It is connected to a character tube and is shut off from the outside by the sealing water 12. On the other hand, the tableware stored in the tableware basket 2 is washed by the cleaning water ejected from the nozzles 31 while the rotary blades 3 provided at the bottom of the cleaning tank 1 and provided with a plurality of nozzles 31 on the blades rotate. In FIG. 1, reference numeral 5 indicates a cover of the dishwasher.

According to the normal use method, since there is a cleaning operation including a cleaning step and a rinsing step, cleaning water is sequentially supplied, and fresh cleaning water is always supplied to the sealing water 12 in the cleaning water storage section 11. Is stored as a fixed amount. But,
As described above, if only the drying operation is often performed, there is no replenishment of the washing water, so that there is a problem that the sealing water is decomposed and unsanitary, and an offensive odor is generated. Therefore, in the dishwasher according to the present application, the cleaning tank 1 is provided with the water supply means 4 capable of arbitrarily supplying water to the cleaning water reservoir 11.

The water supply means 4 is usually connected to tap water, for example, a control valve 4 incorporating a timer.
1, the water supply is performed every predetermined time, for example, for several seconds to several minutes regardless of the presence or absence of the cleaning operation and the drying operation.
Alternatively, the water may be supplied every predetermined time after the cleaning operation. By performing the above-mentioned water supply, the sealing water 12 stored in the cleaning water storage portion 11 is replaced at regular intervals, and the sealing water does not rot or run out.

In any of the above cases, it is preferable that water is poured into the wash water storage portion 11 so as to flow downward along the wall surface of the wash tank 1 as shown in FIG. More preferably, a guide cover 42 is provided to keep the dried dishes from getting wet by the water injection. Further, after operating the water supply means 4, it is preferable to interlock a fan (not shown) to ventilate the cleaning tank for a certain period of time. By doing so, it is possible to prevent dew condensation on the dried tableware.

In the dishwasher shown in FIG. 2, the cover
The state of the bottom part of the washing tank 1 in the state where 5 is opened and the dish basket 2 is removed is shown by a partially cutaway perspective view. As described above, by simply providing the water supply means 4 in the cleaning tank 1, the sealing water 12 of the cleaning water storage portion 11 formed at the bottom of the cleaning tank 1 is not spoiled or the sealing water is not cut off. It is clear that we can always provide a dishwasher with a trap function.

[0012]

The dishwasher according to any one of claims 1 to 5 comprises a washing operation including a washing step of washing the dishes stored in the dish basket and a rinsing step of rinsing the washed dishes, and a drying operation. With a cleaning tank for performing, the cleaning water from the cleaning step and the rinsing step is stored as a fixed amount in the cleaning water storage portion formed at the bottom of the cleaning tank as sealing water, and the fixed amount of cleaning water is In the dishwasher that was sequentially drained, the above-mentioned wash water storage unit was provided with a water supply means capable of arbitrarily supplying water. It will not be replaced and the sealing water will not rot or run out of water.
There is a common effect that.

In addition to the above common effects, the dishwasher according to a second aspect of the present invention has a control in which, for example, a timer is incorporated at predetermined time intervals regardless of whether or not a washing operation including a washing step and a rinsing step is performed.
