Abstract

The invention provides a cleaning machine which comprises a high-pressure pump, a motor assembly, a control assembly and a shell, wherein the motor assembly comprises a motor for driving the high-pressure pump to operate, fan blades arranged on the motor and a fan housing for accommodating the motor; and the shell is internally provided with a first accommodating cavity for accommodating the motorassembly, the second accommodating cavity for accommodating the control assembly, and a partition plates for separating the first accommodating cavity and the second accommodating cavity. The shell is further provided with an air inlet part and an air outlet part; the air inlet part, the first accommodating cavity, the fan housing and the air outlet part form a first air duct; and the air inlet part, the second containing cavity and the air outlet part form a second air duct. Compared with the prior art, the cleaning machine provided by the invention has double heat dissipation air ducts which do not interfere with each other, so that the problem of mutual interference between the heat dissipation of a motor and the heat dissipation of a high-power controller is solved. The heat dissipation effect of the motor and the high-power controller is improved, the performance of the cleaning machine is improved, and the service life of the cleaning machine is prolonged.

Description

technical field

[0001] The invention relates to a cleaning machine, in particular to a high-pressure cleaning machine with a double air duct system. Background technique

[0002] The heating unit of the washing machine mainly includes a motor and a high-power controller. In order to prevent the performance of the cleaning machine from being overheated by the motor and the high-power controller, it is usually necessary to dissipate heat from the motor and the high-power controller. For example, Chinese Patent No. 201620805777.X discloses a heat dissipation structure. In the heat dissipation mechanism, the high-power controller is placed on the heat dissipation air duct of the motor, so that the high-power controller is cooled and dissipated by the cold air sucked in by the heat dissipation fan on the motor. However, this heat dissipation method will affect the heat dissipation effect of the motor, thereby affecting the performance and service life of the cleaning machine. ...
