Embodiment 1

[0039] Such as Figure 1 to Figure 2 As shown, this embodiment discloses a dishwasher washing pump. The washing pump is installed in the dishwasher and communicated with the spray arm of the dishwasher, and is used to provide high-pressure washing water for the spray arm, so that the spray arm rotates rapidly under the reaction force of the sprayed washing water. At the same time, the high-pressure washing water is sprayed onto the tableware to realize the washing of the tableware by the dishwasher. From the washing principle of the dishwasher, it can be known that the washing effect of the dishwasher is directly related to the working efficiency of the washing pump, that is, the pressure of the washing water provided by the washing pump.

[0040]However, in the actual work of the dishwasher, local pressure loss is often caused at the washing pump, seriously affecting the useful output power of the washing pump. The so-called local pressure loss refers to the pressure loss c...

Embodiment 2

[0050] The difference between this embodiment and embodiment 1 is that the guide part in embodiment 2 is a cylindrical water guide column that protrudes from the inner surface of the pump casing and fits closely with the surface. Similar to Embodiment 1, the height of the water guiding column is smaller than the height of the cavity; and it is located at the place where the water flow generates a vortex in the cavity. The function of the water-guiding column is similar to that of the above-mentioned water-guiding ribs, which change the direction of the original water flow, break up the vortex flow, eliminate the vortex area and dead water area, thereby reducing the local pressure loss of the washing pump.

[0051] Furthermore, the number, height and thickness of the water guiding pillars in Embodiment 2 vary according to the water flow intensity at the inner cavity where the water guiding pillars are located. Therefore, the effective power of the washing pump can be guaranteed...

Embodiment 3

[0053] The difference between this embodiment and Embodiment 1 and Embodiment 2 is that the guide part in Embodiment 3 is a strip-shaped guide groove with a curved curve that is recessed on the inner surface of the pump casing; One end of the diversion groove is located at the beginning of the water flow vortex in the pump casing, and is tangent to the water flow vortex at this place. Of course, similar to the above-mentioned embodiment, the length, depth and quantity of the diversion groove are also related to the strength of the vortex water flow at the position. When the vortex water flow intensity is relatively high, the diversion groove here should be selected with a longer length. , and or deeper, and or more diversion grooves.

Abstract

The invention discloses a dishwasher washing pump and a dishwasher. The dishwasher includes a spray arm. The washing pump includes a pump housing with an inner cavity. In communication, a guide part is provided in the inner cavity of the pump casing, and part of the structure of the guide part is located in the projection of the opening on the inner cavity, and the guide part is used to guide the water flow in the pump casing to change. The direction of movement breaks up the vortex and reduces the local pressure loss of the water flow. The present invention eliminates the energy loss caused by "dead water area" or "vortex area" in the washing pump, thus improving the working efficiency of the washing pump.

Description

technical field [0001] The invention belongs to the field of kitchen equipment, and in particular relates to a dishwasher washing pump and a dishwasher. Background technique [0002] With the improvement of living standards, people have higher and higher requirements for the quality of life, and thus higher and higher requirements for product quality, performance, user-friendly use, and intelligent operation. As an excellent product, the dishwasher has gradually entered people's lives. Dishwasher is a device that automatically cleans tableware such as bowls, chopsticks, plates, plates, knives, forks, etc. It can reduce labor intensity, improve work efficiency, and improve cleanliness. The water used in the washing cycle of the dishwasher is circulating water, and the sink of the dishwasher cooperates with the bottom of the liner as a container for storing the circulating water. During the washing process of the dishwasher, the circulating water flows into the washing pump ...
