DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a dishwasher in which a washing tank is drawn out of a dishwasher main body, and the dishes are stored in the washing tank to wash the dishes.

[0002]

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

[0003] As shown in the figure, a dishwasher main body 1 is provided with a washing tank 2 having an opening at the front, an upper opening inside, and a drawer 2 which can be pulled out forward from the dishwasher body 1. A tableware basket 4 for storing the tableware 3 is provided. Cleaning tank 2
Is provided by the rails provided in the dishwasher body 1 and the washing tank 2,
It can be pulled out forward.

In the cleaning tank 2, a heater 5 is provided as a heating means for heating the cleaning water in the cleaning tank 2.
A cleaning pump 6 is provided on the lower surface of the table, and cleaning water is injected from a cleaning nozzle 7 to wash the tableware 3 stored in the tableware basket 4. The water supply valve 8 supplies tap water to the washing tank 2. The washing water in the washing tank 2 is drained by a drain pump (not shown).

The temperature sensor 9 is formed of a thermistor, and is attached to the lower surface of the cleaning tank 2 and input to the control device 10 to detect the temperature of the cleaning water in the cleaning tank 2 and control the temperature of the cleaning water by the control device 10. In addition, the temperature is controlled during the drying process. An inner lid 11 is fixedly provided on the dishwasher main body 1 on the upper surface of the washing tank 2.

[0006] The inner lid 11 is provided inside the dishwasher main body 1 and closes an upper opening of the washing tank 2 when the washing tank 2 is stored in the dishwasher main body 1.

[0007] As means for closing the opening above the washing tank 2, a compressor (not shown) is provided in the dishwasher main body 1, and air is injected into the sealing packing 12 to close the upper part of the washing tank 2. Inflate. Alternatively, the inner lid 11 may be made movable inside the dishwasher main body 1, and the inner lid 11 may be moved in conjunction with the movement of the washing tank 2 to cover the upper part of the washing tank 2. A door 13 is provided on the front surface of the cleaning tank 2.

The operation of the above configuration will be described. The user pulls out the washing tub 2 forward, places the tableware 3 in the dish basket 4, stores it in the washing tub 2, and puts the detergent therein.
Is stored in the main body 1 of the dishwasher, the operation is started by closing the upper opening of the washing tank 2 with the inner lid 11, and the control device 10 controls the heater 5, the washing pump 6, the water supply valve 8, and the drainage pump. And the like, and the tableware 3 stored in the tableware basket 4 is washed, rinsed and dried.

[0009]

In such a conventional configuration, when the tableware 3 is taken in and out during the washing operation or the like, a temporary stop switch (not shown) provided in the control device 10 is pressed, and then the door 13 is opened. Opening and closing are performed, but if this operation is performed quickly, there is a problem that high-temperature washing water scatters outside the machine, which may cause water leakage or burns.

[0010] Further, if the hermeticity of the inner lid 11 engaging the cleaning tank 2 and the opening thereof is insufficient, there is a problem that water leakage occurs.

In addition, when the tableware 3 is taken in and out during the washing operation or the like, when the door 13 is opened and closed carelessly without pressing the stop switch, high-temperature washing water scatters outside the machine, and water leakage occurs. There has been a problem that it may cause burns.

Further, if foreign matter or the like is caught between the cleaning tank 2 and the inner lid 11 which engages with the opening, a gap is formed and the airtightness becomes insufficient. There was a problem that leakage occurred.

Further, when the washing tank 2 is not securely housed in the dishwasher main body 1, there is a problem that water leakage occurs when the washing tank 2 is operated in that state.

The present invention solves the above-mentioned problems, and even when tableware is taken in and out during a washing operation or the like, high-temperature washing water is scattered outside the machine to completely prevent water leakage or burns. It aims to prevent and improve safety.

[0015]

According to the present invention, in order to attain the above object, a washing tank containing tableware which is opened upward can be pulled out from a dishwasher main body substantially horizontally, and the washing tank is washed. When stored in the machine body, the opening of the washing tank is covered and sealed by the inner lid, and the operation can be started by the output of the state detecting means for detecting the operable state.

Thus, even when the tableware is taken in and out during the washing operation or the like, the high-temperature washing water scatters outside the machine, and it is possible to completely prevent water leakage or burns from occurring. Can be improved.
