Abstract

PURPOSE:To prevent a lowering of washing capacity due to the clogging of a filter and the re-deposition of fine garbage to tablewares by collecting the garbage in a washing solution in the garbage sump part of a solid-liquid separator at the time of washing and rising operations and discharging the garbage collected in the garbage sump part to the outside of the machine. CONSTITUTION:At the time of washing and rinsing operations, the washing solution containing garbage sent from a washing pump 15 falls while swirling along the inner wall of the outer periphery of a body part 10a and a part of said solution enters a garbage collection part 10b and the other part flows out to a washing nozzle from an outflow pipe part 12. The garbage contained in the solution enters the garbage collection part 10b by centrifugal force and does not return to the body part 10a because of a barrier plate 14 and the solution flowing out of an outflow pipe part 12 contains no garbage and a clean solution is injected from a washing nozzle 9. At the time of drain operation, the garbage collected in the garbage collection part 10b passes through a drain port part 13 by a drain pump 16 to be discharged out of the machine.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a dishwasher for washing tableware.

BACKGROUND OF THE INVENTION Conventionally, this type of dishwasher has been constructed as shown in FIG.

That is, the cleaning pump 2 attached to the center bottom of the cleaning tank 1 sucks the cleaning liquid in the cleaning tank 1, and injects it from the plurality of injection ports 4 of the cleaning nozzle 3 rotatably arranged in the cleaning tank 1. The tableware stored in the washing tank 1 is washed and rinsed. At this time, the leftover food adhering to the tableware was captured on a substantially dish-shaped filter 6 placed in the bottom opening of the cleaning tank 1 that communicated with the suction side of the cleaning pump 2. .

Problems to be Solved by the Invention However, with such a structure, the mesh of the filter 6 must be made fine in order to collect the leftover food, and as a result, most of the leftover food attached to the tableware is removed. is this filter 6
When there is a large amount of leftover food, the filter 6 becomes clogged, leading to a decrease in the capacity of the cleaning pump 2, resulting in a decrease in cleaning performance. Furthermore, when the dishwasher is finished running, a lot of leftover food remains on the filter 6, which gives the dishwasher user a sense of uncleanliness, and even during the rinsing operation, the rinsing liquid is constantly filled with leftover food. However, there was a problem in that small pieces of leftover food passed through the mesh of the filter 5 and re-adhered to the tableware.

In view of the above-mentioned problems, the present invention has been developed so that cleaning performance is not reduced even when the amount of leftover food is large, there is little re-adhesion of small leftover food to tableware, and the amount of leftover food remaining in the washing tank at the end of operation is To provide a dishwasher which has less waste and does not give a user a feeling of uncleanliness.

Means for Solving the Problems and In order to achieve the above objects, the present invention provides a cleaning tank for storing tableware therein, a cleaning nozzle having a plurality of injection ports for spraying cleaning liquid, etc. A cleaning pump that sucks in cleaning liquid, etc., a drainage pump that discharges cleaning liquid, etc. from the cleaning tank to the outside of the machine, an inlet to which the discharge side of this cleaning pump is connected, and an outflow pipe connected to the cleaning nozzle. a liquid separator, the solid-liquid separator rotates the water flow from the inlet to separate leftovers and liquid by centrifugal action, and introduces the separated liquid into the outflow pipe; It consists of a leftover collection section that collects leftovers after separation, and has a configuration in which a drain port provided in the leftover collection section is connected to the suction side of the drainage pump.

Operation With the above configuration, during cleaning and rinsing operations, the leftovers in the cleaning liquid are collected in the leftovers reservoir part of the solid-liquid separator, and one ton of leftovers is collected in the liquid injected from the cleaning nozzle. It will no longer be included. Further, during the drain operation, the leftover food collected in the leftover food storage section is discharged to the outside of the machine, so that no leftover food remains inside the dishwasher when the operation of the dishwasher is finished.

EXAMPLE Hereinafter, an example of the present invention will be described based on FIGS. 1 to 4.

In FIGS. 1 and 2, reference numeral 6 denotes a cleaning tank installed inside an outer casing 7, in which a rotatable cleaning nozzle 9 having a plurality of injection ports 8 is provided at the center bottom. Further, below the cleaning tank 6, there is a cylindrical body 10 a and a body 10 a having a cylindrical shape.
It has a cylindrical debris collecting part 1Qb with a larger diameter than a, and an inlet 11 is provided in the upper part of the body part 10a in the tangential direction of the cylinder.

Further, an outflow pipe part 12 is provided on the upper surface of the body part 10a, parallel to the axis of the cylinder, one end of which is inserted into the body part 10a, and the other end facing outside of the body part 10a. Collection part 10
A drain port 13 is provided at the lower part of b, and a solid-liquid separator 10 is further provided in which a disk-shaped baffle plate 14 is provided in the leftover food collection section 1ob. The discharge side of the cleaning pump 15 and the inlet 11 of the solid-liquid separator 10 are connected, the cleaning nozzle 9 and the outflow pipe section 12 of the solid-liquid separator 10 are connected, and the drain pump 16 and the A drain port 13 of the solid-liquid separator 10 is connected.

Moreover, 17 is a foreign matter intrusion prevention filter placed on the bottom opening of the cleaning tank 6, and has relatively large eyes.

Next, the operation of the configuration of this embodiment will be explained. FIG. 3 shows the state inside the solid-liquid separator 10 during washing and rinsing operations, and FIG. 4 shows the state inside the solid-liquid separator 10 during a drainage operation. First, during washing and rinsing operations, as shown in FIG. 3, the washing liquid containing leftover food sent from the washing pump 16 descends while swirling along the outer peripheral inner wall of the body 10a, and some The remaining part enters the waste collection part 1ob, and the other part flows out from the outflow pipe part 12 to the cleaning nozzle.

At this time, the leftovers contained in the liquid are driven outside by the centrifugal force, enter the leftover collection part 10b, and do not return to the body part 10a due to the baffle plate 14, but are removed from the outflow vibrator part 12. The liquid that flows out will not contain leftovers. Therefore, the leftover food in the washing and rinsing liquid is collected by the solid-liquid separator 10 into the leftover food collection section 1.
A clean liquid collected by the ob and containing no leftover food is sprayed from the cleaning nozzle 9. Next, during the draining operation, as shown in FIG. 4, the leftovers 18 collected in the leftovers collecting section 1ob are discharged to the outside of the machine through the drain port 13 by the drainage pump 16.

As is clear from the above configuration, during the washing and rinsing operations, the leftover food contained in the washing and rinsing liquid is separated and collected by the solid-liquid separator 10, so that the liquid injected from the washing nozzle contains the leftover food. , and can be rinsed with clean water, and the collected leftovers are discharged outside the machine when draining, so all the leftovers except for large foreign objects and leftovers that are collected by the foreign matter intrusion prevention filter 17 are kept inside the machine. It does not remain in the

In this example, the solid-liquid separator was provided with a baffle plate, but the liquid and leftover food can be separated even without this baffle plate.In short, the solid and liquid can be separated by centrifugal force, and the separated solid Any configuration that can accommodate the following is acceptable.

Effects of the Invention As is clear from the above embodiments, the present invention collects leftover food using a solid-liquid separator using centrifugation, which reduces cleaning performance due to clogging of the filter and prevents fine residue from being collected. It is extremely hygienic as it prevents vegetables from re-adhering to tableware, and the collected leftovers are discharged outside the machine at the end of operation. In addition, since it can be rinsed with clean water that does not contain leftover food, it can give the user a sense of cleanliness.
