Problems solved by technology

[0002] The structure of the existing wet and dry motor cover cannot take into account both noise reduction and cooling. The current motor heat dissipation structure requires a relatively large space to discharge heat in time, and a multi-layer motor cover is required for noise reduction.
If you add a multi-layer motor cover, it will cause the hot air to circulate inside, and then the temperature of the motor will rise sharply

Abstract

The invention discloses a heat dissipation and noise reduction structure of a dry-wet dual-purpose motor. The heat dissipation and noise reduction structure comprises a motor cover and a motor chamberarranged in the motor cover, wherein multiple cooling air inlets are formed in the upper end of the motor cover, a sucked air inlet is formed in the lower end of the motor cover, an air outlet is formed in a side wall, an air outlet channel communicated to the air outlet is formed between the motor chamber and the motor cover and surrounds the motor chamber, a heat dissipation cavity communicatedto the cooling air inlets is formed between the motor body and the motor chamber, multiple heat dissipation air discharging channels separated from the air outlet channel are formed between the heatdissipation cavity and a heat dissipation air outlet formed in a dust collector shell, a housing for suction blades of the motor, the lower end of the motor cover and the motor chamber form an eddy cavity spaced from the heat dissipation cavity, an inlet of the eddy cavity is communicated to an air suction channel in the motor, and an outlet is communicated to the air outlet channel. The heat dissipation and noise reduction structure conducts heat dissipation on the motor through one-way flowing of multiple gusts of cooling air and can improve the heat dissipation efficiency and form a multi-layer sound-insulated noise reduction structure.

Description

technical field [0001] The invention relates to the technical field of vacuum cleaners, in particular to a heat dissipation and noise reduction structure for a wet and dry dual-purpose motor. Background technique [0002] The structure of the existing wet and dry motor cover cannot take into account both noise reduction and cooling. The current motor heat dissipation structure requires a relatively large space for timely discharge of heat, and a multi-layer motor cover is required for noise reduction. If a multi-layer motor cover is added, the hot air will circulate inside, and then the temperature of the motor will rise sharply. For solving this contradiction, the present invention thus comes. Contents of the invention [0003] In view of the problems in the prior art, the purpose of the present invention is to provide a heat dissipation and noise reduction structure of a wet and dry motor, which can improve the heat dissipation efficiency of the wet and dry motor and re...
