Open water pump and water tank groove cleaning machine with same

Abstract

The invention discloses an open water pump which comprises an impeller, a containing cavity and a water outflow part. The impeller comprises a center shaft and a plurality of blades which are evenly arranged on the peripheral face of the center shaft in the peripheral direction. A plurality of water spraying holes are formed in the top face of the water outflow part, and the impeller is placed in the containing cavity. The open water pump is characterized in that a water inlet is formed in a top end opening of the containing cavity, a water outlet is formed in the side face of the containing cavity, the water outflow part is communicated with the water outlet, and a filtering plate is arranged on the water inlet. The invention further discloses a water tank groove cleaning machine with the open water pump.

Description

technical field [0001] The invention relates to a water pump, especially an open water pump, and a sink type cleaning machine using the open water pump. Background technique [0002] A dishwasher is a device that sprays cold or hot water onto dishes to remove dirt adhering to the dishes and to clean the dishes. [0003] Existing use more is the spray type dish washer, as a kind of dish washer disclosed by the Chinese patent of application No. In the upper structure, there is a bowl basket suspended between the two spraying arms, a three-way valve is provided between the water pump and the spraying arm, the water outlet of the water pump is connected to the valve by an outlet pipe, and the valve is connected to the spraying arm. The arms are connected by water pipes; another example is a dishwasher disclosed in Chinese patent application No. 201220385247.6, the dishwashing chamber is divided into an upper dishwashing chamber and a lower dishwashing chamber, and the spray dev...

AI Technical Summary

Problems solved by technology

[0006] For the above-mentioned open water pump, since the water inlet of the water pump is located at the bottom (bottom water intake), the water outlet is located at the side of the upper section of the impeller, and the impeller needs to draw water from the bottom to the upper casing above to discharge water. Therefore, for the impeller The shape and structure requirements of the blade are relatively high; and when it is applied to the sink type washing machine, it is necessary to separately set the draining plate and the draining area in the sink body, which makes the cleaning machine more parts, and the processing technology of the impeller and the sink body is complicated , for which further improvement is needed
