Description

Laundry treating apparatus and control method of laundry treating apparatus Technical Field The embodiment of the application relates to the household appliance technology. And more particularly, to a laundry treating apparatus and a control method of the laundry treating apparatus. Background The start-stop button is an important control part of the clothes treating apparatus, and controls the working state of the clothes treating apparatus barrel. Because the working state of the clothes processing equipment barrel relates to the safety certification work, when the controller and the display board are two independent circuit boards, the start-stop button on the display board is pressed, and a start-stop signal needs to be transmitted to the controller. And after receiving the signal, the controller controls the whole machine to start or stop. The start-stop signal needs to ensure the reliability of the start-stop signal in the process of being transmitted from the display panel to the controller. In the related art, the start-stop signal may be transmitted through a high-low level. When the start-stop button is not pressed, the start-stop signal is high level, and when the start-stop button is pressed, the start-stop signal is low level. The controller determines whether the start-stop button is pressed according to the level state of the received start-stop signal, so as to control the clothes treatment equipment after the start-stop button is determined to be pressed. Because the controller and the display panel are two independent circuit boards, a separate communication harness is required to transmit the start and stop signals. Because the transmission path is longer, start and stop signal receives external interference easily to cause the erroneous judgement of start and stop button, lead to the clothing processing equipment to start and stop the reliability of control lower. Disclosure of Invention The embodiment of the application provides a clothes treatment device and a control method of the clothes treatment device, which can be used for solving the problems that in the related art, the clothes treatment device is easy to be interfered by the outside through high and low level transmission of start and stop signals, so that the start and stop buttons are misjudged, and the reliability of start and stop control of the clothes treatment device is lower. In a first aspect, an embodiment of the present application provides a laundry treatment apparatus including: The power on/off circuit comprises a first switch, wherein when the first switch is disconnected, the power on/off circuit generates a first frequency signal, and when the first switch is closed, the power on/off circuit generates a second frequency signal, wherein the frequencies of the first frequency signal and the second frequency signal are different; The controller is connected with the start-up circuit and is used for receiving the first frequency signal and the second frequency signal, the controller is used for controlling the clothes treatment equipment to work or not work, and the controller is configured to: And controlling the laundry treating apparatus to be operated or not operated when the second frequency signal is received. The embodiment of the application provides a clothes treatment device, because the frequencies of a first frequency signal generated when a first switch is opened and a second control signal generated when the first switch is closed are different, a controller can determine whether the received signal is the first frequency signal or the second frequency signal based on the frequency of the received signal, and further determine whether the first switch is closed or not, so that the clothes treatment device is controlled to work or not when the first switch is closed. In some embodiments of the present application, the start-stop circuit further includes at least two capacitors; the start-up circuit generates a first frequency signal and a second frequency signal, the first frequency signal and the second frequency signal are determined by the equivalent capacitance value of the enabled capacitor in the at least two capacitors, and the first switch is used for changing the enabled capacitor. The embodiment provides a start-stop circuit, because the first switch is used for changing the enabled capacitance, when the first switch is opened and closed, the enabled capacitance will have a difference, and therefore the equivalent capacitance value of the enabled capacitance will also change. Since the equivalent capacitance value affects the frequency of the signal generated by the power on/off circuit, when the equivalent capacitance value is different, the frequencies of the first frequency signal and the second frequency signal generated by the power on/off circuit are also different. In some embodiments of the present application, the start-stop circuit further comprises an inverter, a first resistor, a
