Description

Dryer in dishwasher {Dryer in machine for washing tableware}

The present invention relates to a dishwasher, and more particularly, to a drying apparatus of a dishwasher for reducing the drying time by forcibly discharging the wet steam in the washing machine.

In general, a dishwasher is a dish-washing process by sequentially washing, rinsing, and drying. In the conventional method for drying during the process, the dishwasher includes a heating means at an inner lower portion of the washing tank, and the heating means is provided with a blower fan. The method of natural convection by passing the wind and convection of hot air into the washing tank is used. At this time, the wet steam generated during drying is condensed and collected in the sump provided on the lower side.

However, such a conventional drying method has a problem that not only the drying time is long, but also the drying efficiency is not good. In other words, hot air is blown into the washing tank. After that, the hot air convections naturally in the washing tank and evaporates and absorbs moisture from the dishes. When the heavy moisture vapor comes down, the water grains fall into the sump and the remaining air flows upward. And then flow back into the wash bath.

Therefore, there is a problem in that the drying time becomes longer as the wet steam absorbing the water of the tableware remains in the washing tank continuously. In addition, since it is difficult to completely remove the wet steam in the washing tank, not only does it not perform the function of drying smoothly, but also the residual wet steam condenses on the upper surface of the tub to form water droplets, causing the water droplets to fall on the lower table. There was a problem of lowering the efficiency of dish drying.

Meanwhile, in order to solve such a problem, Korean Utility Model Publication No. 94-7662 provided a drying device of a dish washing machine in which a blower was installed at an upper side of the washing tank to forcibly discharge the wet steam in the washing tank to the outside of the washing tank. Due to the small amount of emission, the drying time is long and there is a problem in that the drying efficiency cannot be maximized. Also, since the motor gasket is combined with the surface contact with the motor shaft, the friction is large and water is easily introduced into the motor to damage the motor. There was a problem.

The object of the present invention is to solve the above-mentioned drawbacks as described above, by forcibly discharging the wet steam in the washing machine to shorten the drying time and at the same time to increase the discharge to improve the drying efficiency, and also the motor gasket It is to provide a drying device of the dishwasher to improve the structure of the dish to reduce the friction as much as possible and to block the flow of water into the motor.

In order to achieve the above object, the present invention installs a blower forcibly discharging the wet steam in the door, and installs a damper between the discharge port and the blower fan of the blower to increase the discharge amount, and the inner diameter of the motor gasket is connected to the motor shaft. In order to prevent the leakage while at the same time to reduce the friction by forming a contact ring.

Hereinafter, the technical configuration of the present invention in detail according to the accompanying drawings.

As shown in FIGS. 1 to 4, in the drying apparatus of the present invention dishwasher, a blower 10 is installed inside the door 1 so that the blower 10 forcibly discharges the wet steam in the washing tank 2 to the outside. In the dishwasher configured to be, the damper 30 is opened and closed about the shaft 31 between the outlet 11 and the blower fan 12 of the blower 10, the motor of the blower 10 In the inner diameter of the motor gasket 40 to be fitted to the shaft 13, a toothed annular jaw 41 is formed, which is characterized by its technical configuration.

Here, the upper and lower portions of the washing tank 1 are provided with shelves 3 on which dishes are placed.

The blower 10 is installed on the upper part of the door 1 as shown in FIG. 1, wherein the blower 10 is disposed between the outer panel 1a and the inner panel 1b of the door 1 as shown in FIG. 2. It is built in.

A motor 14 driving the blower fan 12 is installed at the front of the blower 10, and a cover 15 having a plurality of through holes 15a is installed at the rear of the blower 10. At this time, the lower end of the cover 15 is formed with a drain hole (15b) for discharging the condensed water generated by the condensation of the wet steam into the washing tank (2) during the discharge in the blower (10) during discharge.

The outlet 1 of the blower 10 is in communication with the outside, the through hole 15a of the cover 15 is in communication with the inside of the washing tank (2).

Meanwhile, as shown in FIG. 3, the inner wall of the blower 10 is in line contact with both sides of the damper 30 to reduce friction, and a gap blocking rib 10b that blocks a gap between the damper 30 and the inner wall. Are each formed, the lower end of the outlet 11 is formed with a jaw (11a).

Since the blower 10 is operated by an electric signal when the washing and rinsing stroke of the washing machine is completed, the present invention configured as described above causes the motor 14 to drive the blower fan 12, whereby the suction force is generated in the blower 10. At the same time, the damper 30 is opened while rotating toward the outlet 11 with respect to the shaft 31 by the driving force of the blowing fan 120.

As described above, when the blower fan 12 starts to drive, the wet steam in the washing tank 2 is introduced into the blower 10 through the through hole 15a of the cover 15, and the wet steam introduced into the blower 10 is thus introduced. Forced discharge to the outside through the discharge port (11). At this time, the condensed water generated due to the condensation of the wet steam during the discharge in the blower 10 is discharged into the washing tank 2 through the drain hole (15b) formed in the lower end of the cover 15 is dropped into the catch.

On the other hand, since the motor shaft 13 is in linear contact with the round shaft 41 of the motor gasket 40 when the motor 14 is driven, friction is minimized, and the round shaft 41 is hermetically adhered to the motor shaft 13. Therefore, the inflow of water into the motor 14 is blocked.

Therefore, the present invention, as shown in Figure 3, because the damper 30 is installed between the outlet 11 and the blower fan 12 of the blower 10, the discharge amount is increased to improve the drying efficiency, and also, Figure Inside the motor gasket 40 at 4 With ring 40a and round jaw 41 In the configuration of the ring 41a and the The ring 41a is attached to the motor cover 50. Shape of the ring 50a The parts that make up the rim and the tip are fitted together. Therefore, it has an advantage of reducing the friction of the motor gasket 40 and preventing leakage when using water.

As described above, the drying apparatus of the present invention dishwasher is forcibly discharging the wet steam in the washer to shorten the drying time and increase the discharge rate to the maximum, thereby improving the drying efficiency, and also improving the structure of the motor gasket to improve friction. It is a very useful design that can reduce and block water from entering the motor.
