2 is a view illustrating a state in which a heater according to an embodiment of the present invention is installed.

2, the heater 210 according to the embodiment of the present invention is installed on one side of the bottom surface of the tub 110, and has a shape protruding a predetermined thickness from the bottom surface of the tub 110.

In addition, the upper surface of the heater 210 is formed with a blower opening 211 consisting of a hole of a predetermined size, the hot air through the blower 211 may be supplied to the inside of the tub 110.

In addition, the blower 211 is blocked by the gasket 220 while the dishwasher is in a stroke other than a drying stroke, and the blower 211 is selectively opened and closed by vertical movement of the gasket 220.

In detail, the heater 210 is provided to protrude a predetermined thickness from the bottom surface of the tub 110, and a plurality of hot wires are embedded in the heater 210.

In addition, the air around the heater 210 may be heated to become high temperature dry air by the high temperature heat generated from the heater 210, and the heater 210 may be set to be operated during the drying operation of the dishwasher. However, of course, it can also be used in high-temperature washing administration of the dishwasher.

3 is a view for explaining a gasket according to an embodiment of the present invention, Figure 4 is a view for explaining the process of the dry air flow into the tub by the drying apparatus according to an embodiment of the present invention.

3 and 4, the drying apparatus 200 according to the present invention includes a gasket 220 capable of selectively opening and closing the air vent 211 formed in the heater 210, and the gasket 220 is predetermined. An actuator 230 is included to allow distance movement.

In addition, a connection part 231 connecting the actuator 230 and the gasket 220 is further included.

In detail, the actuator 230 allows the gasket 220 to be opened and closed by moving the gasket 220 up and down.

In addition, the actuator 230 moves the gasket 220 downward so as to form a space in which external air can be supplied into the tub 110, or the washing water may escape through the air vent 211. The gasket 220 may be moved upward to remove the space therebetween.

In addition, the downward movement of the gasket 220 by the actuator 230 may be performed during the drying operation of the dishwasher.

In addition, when the gasket 220 is moved downward by a predetermined distance by the actuator 230, a blower fan 240 is installed to move the high temperature dry air through the blower 211.

In detail, the blowing fan 240 may be formed at a position spaced apart from the gasket 220 by a predetermined distance, and external air is introduced into the drying apparatus 200 by the blowing fan 240, and the introduced outside Air may be moved to the heater 210 and the blower 211 side.

In addition, a fan motor 250 for driving the blower fan 240 is further provided, and a drive shaft 251 for transmitting power generated from the fan motor 250 to the blower fan 240 is further included. .

In addition, a case 260 capable of protecting the actuator 230 and the fan motor 250 is formed at the bottom of the dishwasher.

On the other hand, the operation of the drying apparatus according to the embodiment of the present invention will be described below.

When the dishwasher is operated in a drying stroke, the gasket 220 is moved downward by a predetermined distance by the actuator 230, and thus the air vent 211 formed at the lower side of the tub 110 is opened.

Then, the heater 210 is operated by a predetermined microcomputer, whereby high temperature heat is emitted from the heater 210.

In addition, as the fan motor 250 is driven, the blowing fan 240 rotates at a high speed, and external air is guided to the blower opening 211 by the wind pressure generated by the blowing fan 240. .

In addition, the air guided to the tuyere 211 side is heated to a high temperature by the heater 210, so that the outside air is a high temperature dry air by the heater 210.

The high temperature dry air is quickly introduced into the tub 110 by the wind pressure generated by the blower fan 240, and thus the drying stroke is performed by the high temperature dry air.
In other words, the gasket 220 is moved in a direction spaced apart from the tuyeres 211 so that hot air is introduced into the tub 110 from the drying apparatus accommodating part when the drying stroke is performed. When the stroke is performed, the air outlet 211 may be moved in a direction to cover the blower 211 so that hot air is blocked from entering the tub 110 from the drying apparatus accommodating part.

According to the embodiment of the present invention described above, the effect that the drying performance of the dishwasher can be improved.

By the dishwasher as proposed, the drying operation of the dishwasher has the advantage of allowing the drying of the hot air into the tub by the drying device provided on the lower side of the tub to improve the drying performance.

In addition, the drying performance is improved by allowing the high temperature dry air supplied from the lower side of the tub to be quickly introduced into the tub by the blower fan, and the washing water can be quickly removed from the walls or dishes of the tub to improve aesthetics and hygiene. There is an advantage.

In addition, by allowing the drying of the stored dishes efficiently, there is an advantage that can increase the user's confidence in the dishwasher.
