Problems solved by technology

[0002] At present, electrical appliances such as dishwashers and washing machines usually enter the standby state after work, which causes two problems: on the one hand, because the power supply is not cut off during standby, it is still consuming energy, and if the standby time is longer, it will It causes a great waste of energy, which does not meet the requirements of building an energy-saving society in our country; on the other hand, because the electronic devices of electrical products are always in a charged state when they are in standby, their aging is accelerated and the service life of electronic devices is shortened.
[0003] In order to solve the above problems, the following two methods are usually adopted in the prior art: one is to reduce the standby power consumption of electrical products, and adopt low-power microprocessors and peripheral circuits in product design, so that although it can be Reduce power consumption, but still cannot completely eliminate standby power consumption. At the same time, such a product design increases the cost; another way is that in order to eliminate standby power consumption, the user unplugs the power cord after the electrical appliance is used to completely disconnect the power supply. , and then plug in the power cord when you use it next time. Although this method can completely eliminate the standby power consumption, this method is very inconvenient and increases the workload of the user. Moreover, sometimes it will happen that you forget to unplug the power cord. Happening
[0004] Therefore, there is an urgent need to provide a new technical solution to solve the above-mentioned standby power consumption problem in the prior art

Embodiment Construction

[0023] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0024] Such as figure 1 As shown, according to this embodiment, the zero-standby power consumption control circuit provided by the present invention can be used in various household cleaning appliances, typically, it can be used in dishwashers, washing machines and other appliances. Taking a dishwasher as an example, the control circuit includes a power input terminal, a power output terminal, a light touch switch SW1, a magnetic latching relay K1, a coil drive circuit, a main controller, a memory unit, a switching power supply unit, a display control unit, and a door body Detection unit, motor control unit.

[0025] Among them, the light touch switch SW1 is set between ...

Abstract

The invention relates to the technical field of control of power supply switches, in particular to a cleaning device with zero standby power consumption as well as a control circuit and a control method thereof. The control circuit comprises a power supply input end, a power supply output end, as well as a touch switch, a magnetic latching relay and a coil driving circuit arranged between the power supply input end and the power supply output end, wherein the two ends of the coil of the magnetic latching relay are connected with the coil driving circuit, and a contact switch thereof is arranged between the power supply input end and the power supply output end, and is in parallel connection with the touch switch; the coil driving circuit is used for driving the coil of the magnetic latching relay according to control signals so as to close or open the contact switch of the magnetic latching relay. According to the control circuit provided by the invention, the magnetic latching relay is adopted to enable equipment to automatically cut off the power supply after finishing operations to truly realize zero-power consumption standby; in addition, the equipment is electrified again after losing power in the operation process through the cooperative work between a memory chip and the magnetic latching relay; the electrification is implemented without manually closing the switch.
