Problems solved by technology

The thermostat can only cut off the protection when the temperature of the hot air at the outlet of the air duct is abnormally high. When the temperature of the hot air at the outlet of the air duct reaches the cut-off protection temperature, the temperature of the drying mechanism has reached a relatively high temperature. Unavoidable fire hazard

Embodiment Construction

[0026] The embodiment of the present invention provides a drying mechanism, which can prevent the temperature of the drying mechanism from being too high when the fan motor is not working, thereby reducing the risk of fire.

[0027] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments It is a part of embodiments of the present invention, but not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0028] Please refer to the attached Figure 1-4 , the drying mechanism provided by the embodiment of the present inve...

Abstract

The invention provides a drying mechanism which comprises an air duct, a heater, a fan, a fan motor, a circuit control board and a centrifugal switch for controlling a heating circuit to be connected or disconnected, wherein the circuit control board is provided with the heating circuit for controlling the heater to be on or off and a motor circuit for controlling the fan motor to be on or off; the heating circuit is in parallel connection with the motor circuit, the heater is in series connection with the heating circuit, and the fan motor is in series connection with the motor circuit; and the centrifugal switch is in series connection with the heating circuit and is coaxially connected with the fan motor. When the fan motor rotates, the centrifugal switch is switched on, and when the fan motor stops rotating, the centrifugal switch is switched off. Only on the premise that the fan motor rotates can the heater work. When the circuit control board starts the fan motor and the fan motor cannot rotate due to faults, the centrifugal switch cannot be switched on, and the heater cannot perform heating normally. It is guaranteed that the problem that only the heater works, so that the severe local heating is caused and the drying mechanism is burned down is solved, and hidden fire danger is reduced. The invention further provides a washing machine.

Description

technical field [0001] The present invention relates to the technical field of washing machines, and more specifically relates to a drying mechanism, and also relates to a washing machine with the above drying mechanism. Background technique [0002] The existing washing machine drying mechanism includes: air duct, fan, fan motor, heater, temperature controller and temperature sensor; wherein, the fan is arranged in the air duct; the fan motor is used to drive the electric fan to rotate, to provide air flow in the air duct ; The heater is used to heat the air in the air duct, the thermostat is used for overheating protection, and the temperature sensor is used to detect the temperature of the hot air at the outlet of the air duct. [0003] When the washing machine runs the drying program, the heater heats the air to provide heat; the fan motor drives the fan to rotate to drive the air circulation inside the washing machine, and finally the heated hot air is brought to the cl...
