Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a dishwasher that washes dishes and the like by jetting washing water.

BACKGROUND OF THE INVENTION A conventional dishwasher and a common dishwasher are shown in FIG. In FIG. 3, inside the cleaning tank 3, a filter 5 is located on the food suction side to collect leftover food (contaminants attached to tableware etc. are called leftover food). A drain pipe 8 is connected to a drain pump that drains water. A water supply pipe 7 for cleaning water is connected to the negative part of the cleaning tank 3 . In the dishwasher configured in this manner, the washing pump 4 injects washing water from the bottom of the washing tank 3 from the washing nozzle 2, which is supplied from the water supply pipe, thereby washing off the leftover dishes.

The washing water containing the leftover food is filtered by the filter 5, circulated to the washing pump 4, and repeatedly sprayed from the washing nozzle 2. After a predetermined period of time, the washing water is transferred to the washing tank 3 by the drain pump 6.
Drained outside. Subsequently, the process of rinsing the dishes etc. with newly supplied washing water is added two to three times. The washing water during this step is hereinafter referred to as rinsing water.

Problems to be Solved by the Invention However, in the conventional configuration, the filter 6 is located below the washing water level, so the leftover food collected on the filter 5 while the washing pump is in operation is removed when the washing pump is stopped. \-1 spreads into the cleaning water at the bottom of cleaning tank 3. Therefore, after the washing water is drained, leftovers will be scattered on the bottom of the washing tank 3 in addition to the filter 6, and the leftovers collection performance of the filter 5 will be insufficient, and therefore it will take time to post-process the leftovers. There was a problem.

Further, since the filter 6 is provided in the suction side path of the washing pump 4, the rinsing water passes through the leftover food collected by the filter 5 and circulates during the rinsing process. Therefore, there was a problem that the new rinsing water was contaminated with leftover food.

Furthermore, although the filter 5 is taken out and washed, the part that supports the filter 5 at the bottom of the washing tank 3 is difficult to clean, and cleaning water contaminated with small pieces of leftover food and leftover food tends to remain, making it easy to become unclean. was there.

The present invention is intended to solve these problems, and aims to simplify the post-processing of leftover food and to clean a dishwasher in which rinse water and leftover food are separated.

Means for Solving the Problems In order to solve the above-mentioned problems, the dishwasher of the present invention has a bypass path in which a leftover case equipped with a filter for collecting leftovers is branched from a drainage path and connected to a washing tank. This is a removable device.

Effect: With the above configuration, the leftover food is collected by the leftover stream connected to the bypass path, so that the leftover food can be collected in the filter separately from the washing water at the bottom of the washing tank. Since it is possible to prevent leftover food from scattering on the bottom of the washing tank, post-processing of leftover food is easy. Moreover, the filter is separated from the suction side path of the washing pump, so the rinsing water does not pass through the leftover food.
Contamination of the rinse water with leftovers is prevented. The entire leftover case with a trench filter inside can be disassembled and washed, making it extremely clean.

Embodiment FIG. 1 is a longitudinal cross-sectional view of a dishwasher according to an embodiment of the present invention, and FIG. 2 is a longitudinal cross-sectional view of essential parts of the same embodiment. In the figure, there are 9. dishes inside the washing tank 11. A cleaning nozzle 10 is provided, and a cleaning pump 12 for supplying cleaning water to the cleaning nozzle 10 is provided. The filter 13 that collects leftovers is the leftovers case 1
The leftovers case 17 consists of a case A 17ar and a case B 17b that are removably fitted together. The drain pump 14 is connected to a drain pipe 16 and a bypass path 21 branched in the middle, and a leftover case 17 is attached to the discharge side of the bypass path 21. A protective net 18 that prevents foreign objects such as meat chunks and spoons from being sucked into the cleaning pump 12 from oxen is formed with an opening diameter large enough to allow normal leftover food to pass through. 19 and 20 are
In order to prevent the leftover food from clogging the injection nozzle 10, it is a fixed blade consisting of a rotating blade that crushes the leftover food into small pieces and a large number of holes. 22 and 23 are electromagnetic valves that open and close the bypass path 21 and the drain pipe 16. Also, case A 17
In a, there is a convex portion 21 provided on the inner wall of the cleaning tank in the bypass path 21.
A hook-shaped recess 17c that is removably fitted into the portion a and a connection port 17d to the bypass path 21 are provided.

The operation of the configuration described in Section 2 will be explained below.

When contaminated dishes are set in the dishwasher 9, the washing water 6 is collected at the bottom of the washing tank 11, and the washing pump 12 is operated, the washing water is sent to the washing pump 12 through the protective net 18 and is discharged from the washing nozzle 10. The spray washes away the leftovers from the dishes. The leftover food falls to the bottom of the cleaning tank 11 along with the cleaning water, and the rotary blade 1
The particles are crushed by the fixed blade 9 and the fixed blade 20 and sucked into the washing pump 12, and are again jetted together with washing water from the washing nozzle 10, and this process is repeated. At this time, the solenoid valve 22 is opened and the solenoid valve 22 is opened.
3 is closed and the drain pump 14 is operated at the same time, a part of the washing water is sent to the filter 13 through the bypass path 21, and the leftover food in the washing water is collected by the filter 13 and the leftover food is removed. Cleaning water that does not contain water is sent to the cleaning tank 11. This action causes the water to fall from the dishes, etc., and wash water from the washing pump 12. The leftover food circulating through the cleaning nozzle 10 and the cleaning tank 11 is gradually collected by the filter 13, and the cleaning water becomes free of leftover food. After running for a predetermined period of time, the cleaning pump 12 is stopped, the solenoid valve 22 is closed, and the solenoid valve 23 is opened.The cleaning water is drained to the outside by the drain pump 14 from the drain pipe 16, and the bottom of the cleaning tank 11 is filled with the conventional Tableware 7 \-.

Unlike a washing machine, there are no leftovers left behind.

Next, fresh water is supplied to rinse the dishes, and the washing pump 12 is operated. During this rinsing step, the leftover food is collected on the F side of the washing water surface, so that the leftover food does not spread into the washing water again, unlike in the conventional method. 1~ Since the filter 13 is installed in the drainage path rather than in the suction side path of the cleaning pump as in the conventional example, the rinsing water does not pass through leftover food, allowing fresh rinsing that is not contaminated by leftover food. Dishes are rinsed with water. In this embodiment, the above-mentioned cleaning process once and this rinsing process twice are automatically performed successively, and the cleaning is completed.

As described above, according to this embodiment, by detachably connecting the leftover case 17 containing the filter 13 for collecting leftovers to the bypass path 21, the leftovers at the bottom of the cleaning tank 11 after cleaning are completed. Dispersion is prevented, and since the leftover food is separated from the rinsing water, washing can be completed with fresh, uncontaminated rinsing water. 1. Since the filter 13 can be taken out of the cleaning tank 11 together with the leftover food case 17, disassembled, and washed as a whole, no leftover food or its odor will remain in the cleaning tank 11, making it extremely clean.

DETAILED DESCRIPTION OF THE INVENTION As described in detail, according to the present invention, all of the leftovers can be collected in the filter, making post-processing extremely simple, and cleaning can be performed using fresh washing water that does not pass through the leftovers. It is possible to provide an epoch-making dishwasher in which the entire leftover case containing the inside can be removed from the washing tank and easily washed.
