The present invention relates to a drying control device of the dishwasher, and in particular, by driving the drainage driven when the drainage after washing the dishes in the dishwasher, drying by discharging the air inside the drainage and washing tank through the drain pipe outside The present invention relates to a drying control device for dishwashing, which can increase the effect and at the same time discharge the maximum amount of water remaining in the washing tank.

The conventional dishwasher drying apparatus uses a natural convection method of preheating drying using only the heat inside the washing tank after drying the dish, or operating only the heating member to dry the water, so that water droplets form in the washing tank after drying. There is a problem that occurs a lot, there is also a method to operate a separate blowing means for forced air, which is a hassle to install a separate blowing means, there was also a problem that the residual water in the washing tank is not removed.

In order to solve the above problems, the present invention provides a drying operation time adjuster and a micro switch that allow the drying control device to freely select a drying time. In addition, the drainage driven during drainage periodically drives a predetermined time during drying to discharge the air inside the drainage and washing tank through the drain pipe to increase the effect of drying and to discharge the residual water in the washing tank to the maximum.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

As shown in FIG. 1 and FIG. 2, a jet machine 3 for dispersing water on the lower body 2 of the dishwasher 1, and an inside of the washing water supply device Wp for supplying water for washing. Heating member (H) for drying or heating the washing water, drain (Dp) for draining water, water supply member (Wv) for supplying water, and relay (R) for operating the relay switch (RS / W), each function It consists of a programmer (p) having a drain terminal (Dp1), a washing water supply terminal (Wp1), a water supply member terminal (Wv1), a heating member terminal (H), a dry terminal (D), and a water supply terminal (W) to control In the drying control device of the dishwasher to operate the water supply washing, drainage drying, the water supply terminal (W) of the programmer (P) through the relay switch (RS / W) and the operation time adjuster (TM) for adjusting the time It is connected to the hardening member (H) for drying the washing tank, and the drain terminal (D) is a drain switch (D-SW) and the drain end (D) is connected to the relay (R) through a drying operation time adjuster (SM) to dry for the time selected in the (D), the drain switch (DS / W) is the programmer (through the contact of the micro switch (MS / M) ( It is connected to the heating member terminal h and the heating member H of P), and also to the drain terminal DP, and between the water supply member terminal Wv1 and the water supply member Wv of the programmer P. By connecting the water supply control switch (FS / W), it will be described in detail the operation and effect of the present invention configured as described above.

When the dishes are placed in the dishwasher 1 shown in FIG. 1 and the programmer P is operated, the water supply control switch FS / W is connected to the terminal C from the contact a to the contact b. The water supply member Wv and the relay R are driven to supply water to the washing tank, whereas the terminal C of the relay switch RS / W is connected to the contact a so that the operation time adjuster TM is not driven. The water is then supplied to the washing tank to an appropriate level while the next stroke is impossible to proceed.

Subsequently, when water supply is completed to an appropriate level, the water supply control switch (FS / W) detects this and moves the terminal C from the contact point b to the contact point a to operate the water supply member Wv and the relay R. At the same time, the water supply is stopped and the terminal C of the relay switch RS / w is connected from the contact a to the contact b to operate the operation time adjuster TM, so that the next programmer P Contact terminal (TB ₂ ) of the) is connected to the washing water supply terminal (Wp) to drive the washing water supply (Wp).

At this time, the operation time controller (TM) washes the dishes in the washing tank for the set time, and then, after the washing process, the programmer (P) drives the drain terminal (Dp) to drain the washings in the washing tank by setting the drain (Dp). .

In this way, when the drain is completed and the washing stroke is completed, all the terminals of the programmer (P) are stopped and the terminal (TB) of the programmer (P) is connected to the drying switch (DS / W). By operating the drying operation time controller (SM) for the time selected by the programmer (P) by), and drying the heating member (H) while at the same time periodically operating the micro switch (MS / W).

At this time, when the common terminal COM of the micro switch MS / W is connected to the terminal NC, the drain Dp is driven to drain the residual water in the lower body stage 2, and when the draining is completed, the drain shown in FIG. Drain the air through the drain pipe (DH).

When the common terminal COM of the micro switch MS / W is connected to the terminal NO, the heating member H is driven to maintain the internal temperature of the washing tank at 65 ° C., thereby drying the dishware of the washing machine. That's it.

By repeating the above operation it is possible to more effectively dry the dishwasher.

As described above, the present invention connects the drying operation time controller and the micro switch to the drying apparatus of the dishwasher so that the consumer can freely select the drying time, so that the micro switch is periodically connected / connected by the drying operation time controller. As it is released, the heating element and the drainer are periodically driven to discharge the residual water of the washing tank through the drain pipe when the drainage is driven. When the heating element is driven, the internal temperature of the washing tank is increased and dried. It can provide an advantage to increase the drying effect by not sticking inside.
