The embodiment of the application provides a cabinet door response structure.

Referring to fig. 1, in an embodiment, the cabinet door 100 sensing structure is mainly used for a dishwasher including an inner container (not shown) and a washing pump (not shown), and of course, the cabinet door 100 sensing structure of the present application may be applied to other washing apparatuses with suitable installation structures. The cabinet door 100 induction structure includes a cabinet door 100, a microwave induction device 200, and a main control panel (not shown); the cabinet door 100 is provided with an inner side face and an outer side face which are opposite, the inner side face faces the inner container, the outer side face deviates from the inner container, the inner container can be covered when the cabinet door 100 is closed, and the inner wall face of the inner container and the inner side face of the cabinet door 100 enclose to form a closed washing space; a microwave induction device 200 is installed on the outer side surface of the cabinet door 100, and the microwave induction device 200 can induce the approach of a human body and the movement of a user to open the cabinet door 100; the main control board is arranged in the dishwasher and is electrically connected with the washing pump and the microwave induction device 200, so that the main control board can control the operation of the washing pump in real time according to the signal detected by the microwave induction device 200.

Specifically, in the present embodiment, a dish basket (not shown) for placing dishes to be washed is provided in the inner container of the dishwasher, and the cabinet door 100 can be opened or closed with respect to the opening of the inner container. In a common dishwasher with a side-hung door, one end of a cabinet door 100 is hinged with the edge of one side of an opening of an inner container, and the other end of the cabinet door 100 can be opened relative to the opening of the inner container; of course, in the drawer-type dishwasher, the door 100 may be opened by moving along the rail in a direction away from the inner container, and the basket may be pulled out by moving the door 100 outward. The spraying arm is driven by the washing pump motor to rotate, so that water columns sprayed out of the spraying arm are sprayed onto the bowl basket and the tableware, and water generated by washing is recycled for many times and then discharged through the drainage system. In the actual use process, after putting into tableware, cabinet door 100 closes in order to cover the inner bag, then, the user presses relevant control button in order to start dishwasher automatic operation, however, in the cabinet door 100 design of present common dishwasher, only at the time of cabinet door 100 opening usually, just can detect that cabinet door 100 is opened and then control the washing pump stall, but this moment, because the mechanical inertia of washing pump, the spray arm still can last the rotation of a period of time, and there is not the water that falls yet in the inner bag, like this, when opening cabinet door 100, hot water can spill, and then cause the user to scald.

Based on this structural design, in this embodiment, because be equipped with microwave induction system 200 on the lateral surface of cabinet door 100, so when the human body is close to the cabinet door 100 of dish washer, especially when the user has the operation of opening cabinet door 100, this action just can be very detected by the response of microwave induction system 200, then, microwave induction system 200 gives the main control board with this signal transmission, the main control board just can control the washing pump stall in advance, and thus, when the user opened the cabinet door 100 of dish washer, the washing pump has stopped early, hot water also can not be because of the rotatory spill of the mechanical inertia of washing pump naturally, thereby reached and prevented that the dish washer from opening the door the mesh of dabbling, and then effectively avoided the occurence of failure such as scald that leads to because of the dabbling.

It should be noted that the microwave sensing device 200 in the present application specifically employs radar microwave sensing technology. The radar microwave sensing technology is a detection technology for determining the velocity and position of a moving object by detecting the phase difference between a transmitted wave and a reflected wave by using the doppler effect of microwaves. Here, the microwave means an electromagnetic wave having a frequency of 300MHz to 3000GHz and a wavelength of 1mm to 10 mm. When the microwave emitted by the microwave induction device 200 comes into contact with a human body and returns, the microwave is detected, a distance is calculated according to the round-trip time of the electromagnetic wave, when the microwave is emitted again and reflected back to the microwave induction device 200, another distance is calculated, and then the difference of the moving distance of the human body, namely the phase difference, is judged according to the difference of the two distances, so that the effect of sensing the approach of the human body is realized, and particularly, the operation of opening the cabinet door 100 of a user can be sensed according to the difference of the moving distances of human hands.

Specifically, the microwave sensing device 200 mainly includes several functional modules, such as a microwave transmitting module for transmitting microwaves, a microwave receiving module for receiving the microwaves reflected by the object and returning, and a signal converting module. The main control board is electrically connected to the microwave emitting module to control the microwave sensing device 200 to generate microwaves with corresponding frequencies in real time, and the microwaves are emitted to the front area of the outer side surface of the cabinet door 100 through the microwave emitting module, when a user approaches the area, the human body can reflect the microwaves, microwave signals received after reflection are converted into level signals through the signal conversion module, and then the level signals are output to the main control board through the signal conversion module electrically connected with the main control board, so that the purpose of controlling the washing pump to stop in advance is achieved. Thus, after the user opens the cabinet door 100, the washing pump is stopped, and the problem of water splashing caused by the opened door of the dishwasher is effectively solved. Of course, the transmitting and receiving distances of the microwave sensing device 200 may be adjusted according to the size of the dishwasher, for example, but not limited to, the distance may be 30cm or 40cm moving within the response.

Referring to fig. 1, in an embodiment, in order to facilitate a user to open or close the cabinet door 100, a handle 110 is further disposed on an outer side surface of the cabinet door 100, and a detection direction of the microwave sensing device 200 faces the handle 110, so that an action of a human hand that is about to hold the handle 110 to open the cabinet door 100 can be accurately detected by the microwave sensing device 200, and accuracy of determining opening of the cabinet door 100 is improved. Here, the handle 110 is usually formed from the front side of the cabinet door 100 in a concave manner, but in other embodiments, the handle 110 may be disposed in a convex manner from the front side of the cabinet door 100. Since the door 100 of the dishwasher is usually rotated downwards to open, the handle 110 is preferably disposed at an upper portion of the outer side of the door 100, although in other embodiments, the position of the handle 110 may be designed according to actual requirements. In addition, in both embodiments shown in fig. 1 and 2, other components, such as a display lamp 120, a display screen 130, a skirting board 140, etc., are disposed on the cabinet door 100.

In this embodiment, in order to obtain a better detection effect, an included angle a is formed between the detection direction of the microwave sensing device 200 and the outer side surface of the cabinet door 100, and a is more than 0 degree and less than 90 degrees, that is, an acute angle is formed between the detection direction of the microwave sensing device 200 and the cabinet door 100, and the microwave sensing device 200 is installed on the outer side surface of the cabinet door 100 in an inclined manner, so that it can be ensured that a limited region in front of the handle 110 is within the detection range of the microwave sensing device 200, and thus the motion information of the human hand can be more conveniently and accurately obtained. Specifically, after the human hand enters the detection range, the human hand can be accurately detected, and further, according to the distance change between the human hand and the handle 110, whether the motion of the human hand is about to open the cabinet door 100 is detected and judged, for example, when the human hand is detected to move towards the handle 110, the cabinet door 100 can be judged to be opened, and then before the cabinet door 100 is opened, the main control board can control the washing pump to stop, so that the purpose of preventing the door from opening and splashing water is achieved. It can be understood that if the angle value of the included angle is too large, it is easy to cause misjudgment and further cause the washing pump to stop by mistake, and if the included angle is too small, it will cause too short time for the washing pump to stop in advance, and the effect of preventing the door from opening and splashing water is greatly reduced.

Further, in the present embodiment, the detection viewing angle range of the microwave sensing device 200 is preferably 90 ° to 150 °, and may be further preferably 120 °. Here, the handle 110 is preferably located on the angular center line of the detection viewing angle, so that the area in front of the handle 110 is further ensured to be within the detection range of the microwave sensing device 200, and the misjudgment stop is avoided to some extent.

Further, in the present embodiment, the microwave sensing device 200 is preferably disposed below the handle 110, and is further preferably disposed directly below the handle 110, so as to obtain a better detection range. Specifically, the distance between the microwave sensing device 200 and the handle 110 is greater than the distance between the microwave sensing device 200 and the lower edge of the cabinet door 100, that is, the microwave sensing device 200 is disposed adjacent to the lower edge of the cabinet door 100, and may be disposed on the skirting board 140 in the lower region of the cabinet door 100, so as to further expand the effective detection range of the microwave sensing device 200.

Referring to fig. 1, in the present embodiment, a mounting groove 150 for accommodating a microwave sensing device 200 is disposed on an outer side surface of a cabinet door 100, and an opening of the mounting groove 150 is disposed toward a handle 110, so that microwaves emitted and received by the microwave sensing device 200 can pass through the opening of the mounting groove 150. Certainly, in other embodiments, the microwave sensing device 200 may be disposed on the cabinet door 100 in a protruding manner, but in this embodiment, the concave design of the microwave sensing device 200 can have better aesthetic property without affecting the detection range, and the concave mounting groove 150 can also play a certain role in protecting the microwave sensing device 200.

However, the design is not limited thereto, and the actual position of the microwave sensing device 200 can be set according to actual needs. For example, in another embodiment as shown in fig. 2, the microwave sensing device 200 may be installed on the outer side of the cabinet door 100 in a front manner, but this front installation may cause the dishwasher to stop by mistake due to misjudgment when the user passes by the dishwasher instead of opening the door. Therefore, a more preferable installation manner is the inclined installation manner as shown in fig. 1, in which the microwave transmitting and receiving range of the microwave sensing device 200 can directly sense the movement of the handle 110 pulled by a human hand, and the misjudgment shutdown probability can be effectively reduced.

Further, in the embodiment, the distance between the microwave sensing device 200 and the handle 110 is smaller than the distance between the microwave sensing device 200 and the outer edge of the cabinet door 100, that is, the microwave sensing device 200 is disposed adjacent to the handle 110, so that a limited area in front of the handle 110 can be further ensured within the detection range of the microwave sensing device 200, and the misjudgment rate can also be reduced.

This application still provides a dish washer, and this dish washer includes cabinet door response structure, and the concrete structure of this cabinet door response structure refers to above-mentioned embodiment, because this dish washer has adopted all technical scheme of above-mentioned all embodiments, consequently has all beneficial effects that the technical scheme of above-mentioned embodiment brought equally, and the repeated description is no longer given here.

The above description is only exemplary of the present application and should not be taken as limiting the present application, as any modification, equivalent replacement, or improvement made within the spirit and principle of the present application should be included in the protection scope of the present application.
