Description

Technical Field

[0001] The utility model relates to the technical field related to dishwashers, in particular to a self-locking water diversion structure. Background Art

[0002] Dishwashers are kitchen helpers in homes and businesses. They are devices used to automatically wash bowls, chopsticks, plates, dishes, knives, forks and other tableware to help people reduce the burden of housework.

[0003] The core of a dishwasher lies in the layout of the water channel. The layout of the water channel has a crucial impact on the cleaning effect. In order to improve washing efficiency, the dishwasher divides the water channel to increase the washing flow. The water diversion structure on the market generally uses a synchronous motor to drive the paddle to block and open the water channels in different directions. However, its structure is relatively complex, and the paddle and the water outlet are in hard contact with plastic parts, which cannot be completely sealed and is prone to water leakage, reducing the flushing pressure of the washing water, thereby affecting the cleaning effect of washing dishes.

[0004] In summary, there is a need for a self-locking water diversion structure with a simple structure and easy operation. Utility Model Content

[0005] The utility model aims to overcome the shortcomings of the prior art dishwasher water diversion structure which generally adopts a synchronous motor to drive a paddle to block and open water channels with different flow directions, and its structure is relatively complex, and provides a self-locking water diversion structure with simple structure and easy operation.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] A self-locking water diversion structure includes a dishwasher inner tank, a connecting pipe is fixed to the bottom surface of the dishwasher inner tank, the lower end of the connecting pipe is located outside the dishwasher inner tank and is equipped with a water inlet pipe connector, a partition is fixed inside the connecting pipe, the partition is located above the water inlet pipe connector, a water through hole is provided on the partition, a non-return plate matching the water through hole is installed on the bottom surface of the partition, the upper end of the connecting pipe is located inside the dishwasher inner tank and is equipped with a spray assembly, the spray assembly and the connecting pipe are plugged into each other, the partition is located below the spray assembly, and a lower top column matching the non-return plate is provided at the bottom of the spray assembly.

[0008] When the spray assembly is removed, the water flowing in from the water inlet pipe connector will automatically press the check plate onto the partition and block the water hole, preventing water from leaking from the water hole and preventing water flow from being wasted due to pressure relief. It maintains the water flow pressure very well and improves the cleaning effect of washing; when the spray assembly is inserted into the connecting pipe, the lower top column at the bottom of the spray assembly will automatically press the check plate downward to open the water hole automatically. At this time, the water can flow through the water hole to the spray assembly to spray and wash the dishes. Through this design, users can realize two water distribution methods by removing or inserting the spray assembly. The structure is simple and the operation is convenient.

[0009] Preferably, the check plate is made of an elastic material, and a rib is provided at the edge of the lower end of the water hole to match the check plate. The elastic check plate and the rib seal against each other, preventing water leakage and wasting water pressure, thereby maintaining water pressure and improving the cleaning effect.

[0010] Preferably, a clamp is fixed to the bottom surface of the partition, the clamp being positioned on the side of the water hole. A protrusion is provided on the edge of the check plate, the protrusion having a locking hole that matches the clamp. The clamp and the locking hole are engaged with each other, and the protrusion is installed between the partition and the water inlet pipe connector. During installation, the check plate is mounted on the bottom surface of the partition through the engagement of the clamp and the locking hole, and is secured by the water inlet pipe connector pressing the protrusion on the check plate. This results in a simple structure and easy operation.

[0011] Preferably, the spray assembly includes a spray arm connector, the bottom of the spray arm connector and the upper end of the connecting pipe match each other and are sealed and plugged together, the lower top column is fixed to the lower bottom surface of the spray arm connector, and a spray arm group is sleeved and fixed on the spray arm connector. The spray arm group is internally provided with a water cavity, and the side wall of the lower top column is provided with an axial guide groove, and the water hole and the water cavity are connected by the axial guide groove. When the spray assembly is inserted into the connecting pipe, the lower top column at the bottom of the spray assembly automatically presses the elastic check plate downward, causing the water hole to automatically open. At this time, water flows into the water cavity of the spray arm group through the water hole and the axial guide groove in sequence, and is sprayed out through the spray head on the surface of the spray arm group to wash the dishes. The structure is simple and easy to operate.

[0012] Preferably, the bottom of the spray arm connector is provided with a connecting pipe retaining groove that matches the upper end of the connecting pipe. The connecting pipe retaining groove and the connecting pipe are plugged into each other. A sealing ring 1 is provided within the connecting pipe retaining groove. The spray arm connector and the connecting pipe are sealed via the sealing ring 1. The upper end of the connecting pipe is sealed to the spray arm connector via the sealing ring 1, effectively preventing leakage of washing water, ensuring the flushing pressure of the washing water, and improving the cleaning effect of washing.

[0013] Preferably, a second sealing ring is installed on the water inlet pipe connector, and the water inlet pipe connector and the connecting pipe are sealed by the second sealing ring. The lower end of the connecting pipe is sealed with the water inlet pipe connector by the second sealing ring, which effectively prevents leakage of washing water, ensures the flushing pressure of the washing water, and improves the cleaning effect of washing.

[0014] Preferably, a bowl basket is installed in the dishwasher's inner container, and the top end of the spray arm connector is fixed to the bottom end of the bowl basket. When the bowl basket is loaded into the dishwasher's inner container from top to bottom, the spray arm connector is inserted into the connecting pipe as the bowl basket is loaded. When water is flowing, the weight of the bowl basket effectively fixes the bowl in the vertical direction, preventing water from directly flushing the spray arm connector, thereby improving the fixing effect of the spray arm connector.

[0015] The beneficial effects of the utility model are: two water distribution methods are achieved by removing or inserting the spray component, the structure is simple and the operation is convenient; the sealing is good, it is not easy to leak, and there is no pressure relief and waste on the water flow, the pressure of the water flow is maintained, and the cleaning effect of washing is improved; the fixing effect of the spray arm connector is improved.
