Abstract

The invention discloses a pump cover, a water pump and a water heater, the pump cover comprises a cover body, the cover body is provided with a pump cover water inlet, and the pump cover water inlet is arranged in the center of the top of the cover body; the water outlet connector is provided with a pump cover water outlet, the central axis of the pump cover water inlet is perpendicular to the central axis of the pump cover water outlet, the water outlet connector is connected with the cover body, the water outlet connector is provided with a connecting end connected to the cover body and a free end away from the cover body, and a water passing channel is formed in the water outlet connector. The water passing channel at least comprises a divergent section, and the inner diameter of the divergent section is gradually increased in the direction from the connecting end to the free end. The pump cover has the advantages of being high in reliability and the like.

Description

technical field [0001] The invention relates to the technical field of electric appliance manufacturing, in particular to a pump cover, a water pump with the pump cover and a water heater with the water pump. Background technique [0002] For gas water heaters with zero cold water function, in order to avoid discharging cold water, it is necessary to add a centrifugal water pump to the water inlet pipe to make the water in the pipe flow at a certain flow rate. [0003] For the centrifugal water pump in the related art, long-term use may easily cause damage to the water outlet interface and the pipeline, thereby affecting the service life of the water pump. Contents of the invention [0004] The present invention aims to solve at least one of the technical problems existing in the prior art. For this reason, the present invention proposes a pump cover, which has the advantages of high reliability, long life, etc. [0005] For this reason, the present invention also propos...
