Bowls and dish washing machine

Abstract

A dish washing machine is provided, which comprises a cabinet (1) and is characterized in that the cabinet is provided inside with a water-absorbing cylinder (6) that has a downward-facing opening and four spraying arms (14) at the bottom thereof, the inner cavities of the spraying arms are provided with upward spray holes and communicates with the water-absorbing cylinder, the spraying arms are uniformly arranged to be tangential to the outer wall of the water-absorbing cylinder, the included angle between two adjacent spraying arms is 90 degrees, the opening of the water-absorbing cylinder is provided with filter screens (8 and 10), the water-absorbing cylinder is supported by a bearing against a vertical shaft (4) that passes through the bottom of the water-absorbing cylinder from the filter screens at the bottom of the opening, the vertical shaft is supported on the cabinet by a bearing and rotated by a motor (3), impellers (13) are fixed in the upper part of the vertical shaft inside the water-absorbing cylinder, wipers (7 and 9) are fixed on the vertical shaft below the filter screens and contacted with the bottom of the filter screens, and a drainage port (2) is provided with a drainage valve at the bottom of the cabinet. The dish washing machine has the advantages of good cleaning effect, wide application range, function of automatically cleaning filter screens and removing dirt, and low energy consumption.

Description

technical field [0001] The invention relates to a dish washer, which belongs to kitchen utensils. Background technique [0002] The structure and working principle of some existing dishwashers are as follows: the upper part of the cabinet is a fixed or rotating bracket for placing dishes, and the centrifugal cleaning pump outside the cabinet passes the water in the lower part of the cabinet through the filter screen and then passes through the pipeline. The pump is sent to a rotating spray arm with upward-facing spray holes to spray water onto the dishes for cleaning, and the dirty water after cleaning is discharged out of the cabinet through a centrifugal drain pump. Due to the use of a centrifugal pump and a network of connected water pipes for rinsing the tableware, such a structure causes the following disadvantages in the dishwasher: [0003] (1) The slag cannot be discharged automatically, and the slag will sometimes block the filter screen, resulting in poor water in...

AI Technical Summary

Problems solved by technology

[0003] (1) The slag cannot be discharged automatically, and the slag will sometimes block the filter screen, resulting in poor water intake. After washing the dishes, take out the filter screen by hand, pour out the food residue and rinse it with water, otherwise it will become dirty. Smelly, because the entire dishwashing process cannot be fully mechanized, the current domestic and foreign dishwashing machines can only be regarded as semi-automatic dishwashing machines;

[0004] (2) There is only one spray arm with a length of about 40 cm, and there are 9 spray holes on it (one of which is used to drive the spray arm to rotate, and only 8 actually play a role in cleaning), and the distance between the holes is about 5 cm. The holes are small and the spacing is large, and the centrifugal pump used is outside the washing box. The spray arm in the washing box and the centrifugal pump outside the box must be connected by pipelines, so there is pipeline resistance. Reduce the water speed, so that the improvement of the cleaning rate is limited;

[0005] (3) Since the rotation power of the spray arm is the recoil force generated by spraying water from a spray hole at the farthest end of the spray arm to the rear of the spray arm rotation (the rear refers to the opposite direction of the spray arm rotation), other spray The hole can only be sprayed upwards at a cone angle of 30°. If it is sprayed forward and upward (the front refers to the direction in which the spray arm rotates), the recoil force generated will block the spray arm from moving forward, so that the spray arm cannot rotate; it is only suitable for washing dishes, so foreign countries It is called a dishwasher, and it is used to wash Chinese-style deep bowls. There are dead corners that cannot be washed;

[0006] (4) There is accumulated water in the lower part of the centrifugal pump, which will stink if it is not used for two or three days. The drainage pump is not sealed, and the odor and bugs of the sewer can enter the chassis through the gap between the drainage pipe and the drainage pump to cause pollution.
