Heating pump and washing equipment

Abstract

The invention discloses a heating pump and washing equipment. The heating pump comprises a pump case, an impeller, a flow guidance element, a heating element and a driving element, wherein the impeller can be rotatably arranged in the pump case and comprises a front cover plate, a rear cover plate and a plurality of blades arranged between the front cover plate and the rear cover plate; the middleof the front cover plate is provided with an impeller inlet which communicates with a water inlet; flow channels on the periphery of the front cover plate and the periphery of the rear cover plate form impeller outlets; the blades comprise first blades and second blades, wherein the first blades and the second blades are alternately arranged; the first blades and the second blades are twisted blades which are backwards bent along the radial direction of the impeller from a position near the center of the impeller to the impeller outlets and are arranged at intervals along the radial directionof the impeller; the first blades are near the center of the impeller relative to the second blades; the flow guidance element is arranged above the impeller; and the heating element is arranged in the pump case and covers the outer side of the flow guide element. The blade of the invention can more favorably push a working fluid so as to be favorable for increasing a lift and improving efficiency, and the heating pump is suitable for complex working conditions and requirements.

Description

technical field [0001] The invention relates to the technical field of centrifugal pumps, in particular to a heat pump and washing equipment. Background technique [0002] In the related art, the heat pump is mainly used in washing equipment such as a dishwasher and a washing machine, and is a main component for realizing the washing function. The existing heating pump integrates the heating function into the washing pump. Although it saves space, it often destroys the original flow channel structure, which in turn causes additional hydraulic loss. The head and efficiency of the pump are relatively low, making it difficult to adapt to complex conditions and needs. Contents of the invention [0003] The present invention aims to solve at least one of the technical problems existing in the prior art. Therefore, the present invention proposes a heat pump, which can effectively improve the head and efficiency of the pump, and can adapt to complex working conditions and requi...
