Problems solved by technology

[0003] Due to the use of different button layout styles, resulting in two different operation modes, it is difficult for users to adapt to the changes in operation when replacing home appliances
In addition, the 24-hour standby method is difficult to meet the country's energy-saving requirements due to the need for continuous power supply; and the zero-standby method requires setting the on button and the off button separately, resulting in a waste of cost

Embodiment 1

[0049] This embodiment provides a control method. The control method is used to control the operation process of the household appliance. At least two zero-crossing detection circuits are provided in the household appliance, such as figure 1 As shown, the control method includes:

[0050] 11. Obtain the detection results of each zero-crossing detection circuit during the mains cycle;

[0051] 12. Based on the logical relationship represented by the detection results within a preset time period, determine the current operating state of the household appliance.

[0052] In practice, in order to solve the problem in the prior art that it is necessary to use multiple buttons or button combinations to control the pause and shutdown of household appliances, the embodiment of the present application proposes a method of setting a zero-crossing detection circuit in the household appliance. The detection result of the zero-crossing detection circuit is analyzed, so as to control the h...

Embodiment 2

[0079] The zero-standby power switch for household appliances provided by this embodiment realizes the determination of the switch state of the household appliance by acquiring the operation of the switch buttons by the user, reduces the number of buttons, and reduces the manufacturing cost.

[0080] The present invention provides zero standby power switches such as image 3 As shown, the zero-standby power switch includes a control chip and a control circuit installed in household appliances, and a power supply to the control chip. A switch button is provided in the control circuit, and the switch button is provided with COM1 sampling point, COM2 For at least two sampling points including the sampling point, an LN sampling circuit is provided in the control circuit;

[0081] At least one zero-crossing detection circuit is also provided in the zero standby power switch, and each zero-crossing detection circuit is connected with an LN sampling circuit and at least one sampling ...

Embodiment 3

[0128] Another embodiment of the present invention also proposes a household appliance, in which the zero-standby power switch as described above is provided. A typical household appliance is a washing machine.

[0129] By using the zero-crossing detection circuit to monitor the power supply of household appliances, the control chip can accurately determine the instantaneous power failure of the household appliances, so that only one button can be used to complete the control of the switch of the household appliances, and improve the switching experience of customers sense, reducing the number of keys and reducing manufacturing costs.

[0130] The serial numbers in the above embodiments are for description only, and do not represent the sequence of the components during assembly or use.

Abstract

The invention provides a control method, a zero-standby power switch and a domestic appliance and belongs to the field of domestic appliances. The control method includes acquiring detection results of at least two zero cross detection circuits in the domestic appliance and judging the current operation state of the domestic appliance based on a logic relation indicated by the detection results within a preset time length. According to the invention, accurate judgment on normal switch operation of a user and power instantaneous stop of the domestic appliance can be realized through a control chip, so that control of startup and shutdown of the domestic appliance can be implemented with merely one key, switch operation experience of a customer is improved, key number is reduced and manufacture cost is reduced.

Description

technical field [0001] The invention belongs to the field of home appliances, in particular to a control method, a zero-standby power switch and home appliances. Background technique [0002] The on / off button of zero standby in current home appliances generally adopts the mode of separating the on button and the off button. When the user uses the home appliance, the on button and the off button should be operated separately. In some household appliances with non-zero standby, that is, 24-hour power supply, the switch buttons used are combined into one button, and the micro-controller directly detects the pull-in of the button to realize the judgment of the user's operation. [0003] Due to the adoption of different key arrangement styles, two different operation modes are caused, and it is difficult for the user to adapt to the change in operation when the user replaces the home appliance. In addition, the 24-hour standby mode is difficult to meet the country's energy-savi...
