Problems solved by technology

The traditional centrifugal fan is usually a volute structure. Compared with the straight-in and straight-out axial flow fan, the volute centrifugal fan will change the flow direction of the medium in the fan, but after the position of the air outlet is determined, it is not only impossible to change the position, but also impossib

Abstract

The invention discloses a volute type centrifugal fan with one inlet and two outlets. The volute type centrifugal fan with the inlet and two outlets comprises a volute, blades installed in the volute and a blade motor, wherein the air inlet is formed in the volute; an air cavity is formed inside the volute and on the outer side of the blades; the first air outlet and the second air outlet between which an included angle is formed are formed in the tail of the air cavity of the volute; a reversing baffle is arranged inside the air cavity of the volute and can enable the first air outlet or the second air outlet to be communicated with the air cavity. A new air outlet is additionally arranged at an air outlet of a traditional volute centrifugal fan, and an included angle is formed between the two air outlets, so that when a normal mode and a cold air mode of a heat pump water heater with a cold air function are switched, reversing of media inside the fan needs can be finished as needed by adjusting the reversing baffle. The volute type centrifugal fan with the inlet and two outlets can well meet the requirements of machines. As the automatic switching type reversing baffle is applied to the fan, secondary reversing requirement of the medium inside the centrifugal fan is realized, and the characteristics of high air pressure and low noise of an original centrifugal fan are kept.

Description

technical field [0001] The invention is used in the field of overhead cables, in particular relates to a one-input two-out volute type centrifugal fan. Background technique [0002] At present, the centrifugal fan is applied to the heat pump water heater as a common fan equipment. Compared with the axial flow fan commonly used in the heat pump system, it has the advantages of high wind pressure, low noise, and can change the wind direction. Heat pump water heater. The traditional centrifugal fan is usually a volute structure. Compared with the straight-in and straight-out axial flow fan, the volute centrifugal fan will change the flow direction of the medium in the fan, but after the position of the air outlet is determined, it is not only impossible to change the position, but also impossible Change the flow direction of the medium again, so for the heat pump water heater with air-conditioning function, when switching between the normal mode and the air-conditioning mode,...
