At first, describe the washing operation of dish-washing machine in detail with reference to figure 8,11 and 12 to 14.
When driving washing motor 121, pump impeller 122 rotates.As a result, washings are fed to pump chamber 131 and fluid course control room 132 from collecting tank 110.
At this moment, rotate fluid course control valve 190 so that liquid stream main channel 141 and 142 is connected with fluid course control room 132.Herein, fluid course control valve 190 can optionally be opened one of liquid stream main channel 141 and 142 or open liquid stream main channel 141 and 142 simultaneously.Perhaps, fluid course control valve 190 can alternately be opened liquid stream main channel 141 and 142.
When opening liquid stream main channel 141 and 142, washings are supplied to corresponding washing arm along liquid stream main channel 141 and 142 from fluid course control room 132, so that washings can spray by washing arm.
For example, when placing the fluid course switchboard 192 of fluid course control valve 190 as shown in Figure 12, washings are supplied to upper wash arm 4 (see figure 1)s through liquid stream main channel 142.When placing the fluid course switchboard 192 of fluid course control valve 190 as shown in Figure 13, washings are provided for lower wash arm 5 (see figure 1)s through liquid stream main channel 141.When placing the fluid course switchboard 192 of fluid course control valve 190 as shown in Figure 14, washings are provided for upper and lower part washing arm 4 and 5 through liquid stream main channel 141 and 142.
Different with dish-washing machine commonly used, according to dish-washing machine of the present invention the sampling fluid course is not set.Just because of this, the washings of all suctions are supplied to washing arm.As a result, increased the washing water yield that is ejected into tableware, and the washings of all suctions are used to wash dining set substantially.Therefore, might in dish-washing machine according to the present invention, use the washing pump 120 littler than the load capacity of dish-washing machine commonly used.Simultaneously, significantly reduced the consumption of washings.In addition, simplified the fluid course of washings according to dish-washing machine of the present invention dish-washing machine commonly used relatively.Therefore, reduced the fluid course resistance of washings, thereby although the load capacity of the washing pump of the load capacity of its washing pump 120 and dish-washing machine commonly used is identical, dish-washing machine according to the present invention has strengthened pumping efficiency.
The washings wash dining set that sprays from washing arm and falling on the lid 160.At this moment, because lid 160 tilts to filter element 170, so dirt and the washings fallen on the lid 160 are introduced into top filter 176.Simultaneously, the part washings are introduced directly into collecting tank 110 by the filtering holes 161 of lid 160.
The dirt particle that filter 176 filterings in top are big, and the little dirt particle that lower filter 171 filterings are not filtered out by top filter 176.Therefore, have only the washings that do not contain dirt just to be introduced into collecting tank 110.
According to the present invention, be different from dish-washing machine commonly used, during the washing operation of dish-washing machine, need not periodically to clear up filter element 170.Therefore, although the dish-washing machine that the washing water yield of spraying is used always is few, might provide and the identical washings emitted dose of dish-washing machine commonly used.In addition, reduced the consumption of washings significantly.
Carry out the washing operation of the scheduled time.Along with time lapse, the amount of the swill of collecting in the filter element 170 increases gradually.After washing operation is finished, the drain operation of beginning dish-washing machine.
Below, the drain operation of dish-washing machine will be described with reference to figure 9.
When driving draining pump 180, the washings in the collecting tank 110 are introduced into dirt container cavity 111 because of the suction force of draining pump 180 by lower filter 171.Then, the dirt of collecting in washings and the dirt container cavity 111 is introduced into drain chamber 113.At this moment, because dirt container cavity 111 tilts to drain chamber 113, so dirt is introduced drain chamber 113 smoothly.Subsequently, dirt in the drain chamber 113 and washings through the scupper hose of drain chamber 113 by the outside of releasing.
