Referring to fig. 1 to 3, the present invention further provides a control method of the kitchen electrical appliance, which first detects the state of the door 111 by the door state detecting device 115, for example, when the door state detection device 115 detects that the door 111 is closed, the door state detecting means 115 transmits a door closing signal to the control means 117, and thereafter, if the user moves the foot within a predetermined range of the kitchen appliance, for example, the radar sensor 1141 detects the movement and sends out detection information to the control device 117, the control device 117 generates a control command for opening the door, the automatic door opening/closing mechanism 116 controls the door 111 to open automatically according to the control command for opening the door, and the above-mentioned reciprocating movement may be other movement modes, further, the opening and closing of the door 111 may be controlled by a tool or other body part, not limited to the movement of the foot.
More preferably, referring to fig. 1-3, in order to avoid that the user accidentally triggers the dishwasher 1 to open the door automatically, the control device 117 needs to control the door 111 to open after receiving the detection information of the radar sensor 1141 for a plurality of times within a predetermined time, for example, the predetermined time may be set to be within zero to five seconds, preferably two seconds, within two seconds, if the radar sensor 1141 senses the reciprocating motion of the foot for a plurality of times, for example, two reciprocating motions, the control device 117 sends out two detection information, and then the control device 117 controls the door 111 to open. It should be noted that, since the control principle of the automatic door closing of the dishwasher 1 is basically the same as the control principle of the automatic door opening, the detailed description is omitted.
In a preferred embodiment, referring to fig. 1-3, a plurality of radar sensors 1141 are disposed on the body 11, and a plurality of said radar sensors 1141 are spaced along the width direction of the dishwasher 1, so as to better ensure the accuracy of detection, and to enlarge the sensing range, thereby facilitating the control of the dishwasher 1 by the user. It should be noted that, for example, the door body 111 is provided with the radar sensor 1141, preferably, the body 11 is further provided with a steering mechanism (not shown in the figure), the steering mechanism can be rotated by a gear transmission mechanism or a crank transmission mechanism, the steering mechanism can be provided on the door body 111, and a detection area of the radar sensor 1141 is always located in a specific area by driving of the steering mechanism, and does not change with opening and closing of the door body 111, which is more convenient for a user to control the dishwasher 1, and the user only needs to perform a predetermined operation in the specific area to complete control of the dishwasher 1, such as the above-mentioned opening and closing of the door, it can be understood that other controls of the dishwasher 1, such as control of automatic washing, can also be completed by the user in the specific area in a predetermined manner.
Referring to fig. 1-3, in a specific embodiment, a micro switch is disposed inside the dishwasher 1 for detecting a state of the door 111, and when a door closing signal is detected, the radar sensor 1141 detects a door opening requirement of a user, and when the user has the door opening requirement, the foot of the user moves back and forth within a detection range of the radar sensor 1141, and the radar sensor 1141 detects a moving signal, so as to generate detection information and transmit the detection information to the MCU (control device 117), and the MCU controls the corresponding automatic door opening/closing mechanism 116 to perform a door opening operation. In order to avoid the action of mistakenly opening the door caused by the fact that an obstacle accidentally moves in a sensing area, the radar sensor 1141 is required to detect signals moving back and forth for multiple times in preset time when the door is opened, the preset time is preferably 2 seconds, the detection moving signals are preferably 2 times, the problem that single-point detection is unreliable is avoided, a plurality of radar sensors 1141 can be arranged on the dishwasher 1 to ensure the detection reliability, 2 radar sensors 1141 are preferably selected, the detection reliability can be ensured, and the cost can be saved.
As described above, for the door closing control of the dishwasher 1, a control method similar to the door opening control may be adopted, for example, when the dishwasher 1 opens the door, the micro switch detects the opening motion of the door 111 and sends a door opening signal to the control device 117, and thereafter, the control device 117 controls the automatic door opening/closing mechanism 116 to operate by the reciprocating motion of the user's foot within the detection range of the radar sensor 1141, so as to automatically close the door 111. For another example, the dishwasher 1 may be controlled by other operations, such as controlling the dishwasher 1 to be turned on or off, and in a specific embodiment, when the feet of the user stay within the detection range of the radar sensor 1141 for a predetermined time period, the dishwasher 1 is controlled to be automatically turned on for a washing operation, and the like.
Those skilled in the art will readily appreciate that the above-described preferred embodiments may be freely combined, superimposed, without conflict.
It will be understood that the embodiments described above are illustrative only and not restrictive, and that various obvious and equivalent modifications and substitutions for details described herein may be made by those skilled in the art without departing from the basic principles of the invention.
