[0017] The present invention will be described in more detail below with reference to the accompanying drawings and embodiments.

[0018] The utility model discloses a dishwasher door control device, combined with Figures 1 to 4As shown, it includes a cabinet 1, a door body 2, a skirting board 3, a main control board 4, a first millimeter-wave radar 5, a second millimeter-wave radar 6 and a door opening motion mechanism 7, the door body 2 and the skirting board 3 are arranged on the front side of the cabinet 1, and the skirting board 3 is located below the door body 2, the first millimeter-wave radar 5 is arranged on the door body 2, the second millimeter-wave radar 6 is arranged on the skirting board 3, the door opening motion mechanism 7 is connected between the door body 2 and the cabinet 1, the main control board 4 is arranged in the cabinet 1, the first millimeter-wave radar 5, the second millimeter-wave radar 6 and the door opening motion mechanism 7 are electrically connected to the main control board 4 respectively, and the main control board 4 is used to drive the door opening motion mechanism 7 after successively receiving the human body sensing signal fed back by the first millimeter-wave radar 5 and the foot motion sensing signal fed back by the second millimeter-wave radar 6, and drive the door body 2 to perform the door opening or closing action by the door opening motion mechanism 7.

[0019] In the above structure, the first millimeter wave radar 5 is arranged on the door body 2. The first millimeter wave radar 5 is used to sense the human body passing through the dishwasher. That is, when the user passes through the dishwasher, the first millimeter wave radar 5 feeds back the human body sensing signal to the main control board 4. At this time, the main control board 4 only receives the human body sensing signal and does not perform any control. The door body 2 remains in the previous state. Because the skirting board 3 is located below the door body 2, the skirting board 3 is not easy to sense the user. When the user puts his foot close to the skirting board 3 and shakes or shakes the foot, the second millimeter wave radar 6 senses the foot motion signal and feeds it back to the main control board 4. At this time, the main control board 4 has received the human body sensing signal and the foot motion sensing signal, and needs to control the door opening motion mechanism 7 to perform the corresponding action, that is, use the door opening motion mechanism 7 to drive the door body 2 to perform the door opening or closing action. Based on the above principle, it can be seen that the utility model can obtain the user's door opening and closing instructions in a contactless sensing manner, which effectively improves the convenience of using the dishwasher.

[0020] In order to reduce the occurrence of false sensing events of the second millimeter-wave radar 6, in this embodiment, the door body 2 extends a preset distance to the front side of the skirting board 3. The forward extension of the door body 2 can further block the sensing area of ​​the second millimeter-wave radar 6, so that its sensing area is limited to a partial area below the door body 2.

[0021] On this basis, a concave step opening 10 is formed at the front bottom of the cabinet body 1 , and the skirting board 3 is fixed in the concave step opening 10 .

[0022] In the above structure, see Figure 1 and Figure 2By setting a recessed step opening 10 on the front side of the cabinet body 1, the door body 2 is extended forward as far as possible. Under the combined effect of the thickness of the door body 2 itself and the recessed depth of the recessed step opening 10, the skirting board 3 can be hidden in the recess below the door body 2, and at the same time, the sensing area of ​​the second millimeter-wave radar 6 is reduced. In actual applications, only when the user actively extends his foot toward the second millimeter-wave radar 6 can it sense the foot action signal. Through the above-mentioned structural setting, the main control board 4 can accurately perceive the user's opening / closing door action command to avoid false triggering.

[0023] As a preferred embodiment, the second millimeter-wave radar 6 is embedded in the skirting board 3, and the second millimeter-wave radar 6 is close to the left or right end of the skirting board 3. Specifically, the first millimeter-wave radar 5 is located on the vertical center line of the door panel. When the user stands in front of the door body 2, the first millimeter-wave radar 5 can sense the human body signal. Assuming that the second millimeter-wave radar 6 is also set on the vertical center line of the door panel, it is easy for the first millimeter-wave radar 5 and the second millimeter-wave radar 6 to sense the human body at the same time. In this regard, the utility model staggers the positions of the first millimeter-wave radar 5 and the second millimeter-wave radar 6, and sets the second millimeter-wave radar 6 at a position close to the left or right end of the skirting board 3. When the user stands in front of the door body 2 and needs to open or close the door, he only needs to extend his foot to the lower left or lower right position of the dishwasher to trigger the second millimeter-wave radar 6, thereby further improving the sensing accuracy and further avoiding the occurrence of false triggering events.

[0024] In this embodiment, the first millimeter wave radar 5 is a hidden structure. Specifically, the door body 2 includes a door panel that can pass millimeter wave signals, and the first millimeter wave radar 5 is located at the rear side of the door panel. Regarding the preferred material of the door panel, the door panel is a glass door panel or a thin wooden door panel.

[0025] As a preferred embodiment, the first millimeter wave radar 5 is located on the vertical center line of the door panel, and the first millimeter wave radar 5 is close to the upper end of the door panel. Specifically, the first millimeter wave radar 5 is located in the middle and upper part of the door panel, which enables the first millimeter wave radar 5 to sense human body signals more accurately.

[0026] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions or improvements made within the technical scope of the present invention should be included in the scope of protection of the present invention.
