Washing pumps and dishwashers

Abstract

The invention belongs to the technical field of dish washing machine structures and discloses a washing pump and a dish washing machine provided with the same. The washing pump comprises a lower pump case, an upper pump case and a sealing part. The upper pump case is provided with a first hollow inner cavity. A first spiral diffusion runner is formed in the first hollow inner cavity. The lower pump case is provided with a second hollow inner cavity. A second spiral diffusion runner is formed in the second hollow inner cavity. The upper pump case is fastened and connected to the lower pump case in a rotating buckling mode. An annular groove is formed in the outer wall of the middle of the lower pump case in a concave mode. The sealing part is contained in the annular groove and pressed in the annular groove through the inner wall of the first hollow inner cavity. A guiding column is arranged on the inner wall of the first hollow inner cavity in a convex mode. A guiding sliding groove is formed in the outer wall of the top end of the lower pump case in a concave mode. The guiding column is installed in the guiding sliding groove in a sliding mode. According to the washing pump, on one hand, the diffusion performance of the washing pump is improved, and then the water conservancy efficiency of the washing pump is improved; on the other hand, the production assembly efficiency of the washing pump is improved, and the design machining cost of the washing pump is reduced.

Description

technical field [0001] The invention belongs to the technical field of dishwasher structures, and in particular relates to a washing pump and a dishwasher with the washing pump. Background technique [0002] The washing pump of the dishwasher is assembled from an upper pump casing and a lower pump casing, wherein the upper pump casing and the lower pump casing respectively have a first hollow inner cavity and a second hollow inner cavity, and the upper pump casing is provided with a second hollow inner cavity. A water inlet and a water outlet communicated with a hollow inner cavity. [0003] We know that the connection between the upper pump casing and the lower pump casing should realize both a tight connection and a sealed connection. In order to achieve these two connection effects at the same time, in the prior art washing pump, the upper and lower The connection methods between them can be roughly divided into the following two types: [0004] One is that the upper pu...
