detailed description

The embodiments of the present application are described in detail below. Examples of the embodiments are shown in the drawings, wherein the same or similar reference numerals indicate the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the drawings are exemplary, and are intended to explain the present application, and should not be construed as limiting the present application.

The following describes a door control device for a dishwasher, a dishwasher having the same, and a door control method for a dishwasher according to embodiments of the present application, with reference to the drawings.

FIG. 1 is a block diagram of a door control device for a dishwasher according to an embodiment of the present application.

As shown in FIGS. 1-3, the door control device of the dishwasher includes a driver 100, a detector 200, and a controller 300.

The driver 100 is used to drive the door body M. The detector 200 is disposed above the door body M, and the detector 200 is used to detect the rotation angle of the door body M, or the distance between the detector 200 and the ground or wall. The controller 300 is respectively connected to the driver 100 and the detector 200. The controller 300 is configured to, after receiving the door control instruction, according to the rotation angle detected by the detector 200, or the distance between the detector 200 and the ground or wall, The door body M opening degree is generated, and the driver 100 is controlled to drive the door body M to stop at the door body M opening degree corresponding to the door control instruction.

Specifically, the detector 200 detects the distance between itself and the ground as an example. As shown in FIG. 2 and FIG. 3, the detector 200 is installed on the outer side of the door M, and the detector 200 can detect the height from the ground to the corresponding ground. When the mounting position of the detector 200 on the door M is fixed to L, the opening degree a of the door M is a = arcsin (H / L). It should be understood that this example is applicable to a dishwasher with the door side opened, such as a built-in dishwasher shown in FIG. 3.

In some examples, the door body M of the dishwasher may be disposed on the upper part of the box of the dishwasher, such as a sink dishwasher. At this time, the detector 200 may detect itself from a wall (including a ceiling, a side vertical wall) ), And through this distance, the controller 300 can calculate the opening degree of the door body M.

In addition, the detector 200 can also detect any position of the door body, and the detection accuracy is high, so that the controller 300 can accurately control the door body at any desired target opening angle according to the detected rotation angle, that is, the door body Stop accurately at any position, and then execute corresponding instructions according to the position where the door stops, to achieve automatic control of the dishwasher.

For example, after completing the steps of disinfection and drying of the dishwasher, the door of the dishwasher needs to be opened to release the heat in the dishwasher. If the opening angle of the door of the dishwasher is small, the dishwasher cannot completely release the heat, which will affect the next use. If the opening angle of the door of the dishwasher is large, dust and other materials will enter. The dishwasher causes secondary pollution to the dishes and greatly reduces the washing performance of the dishwasher. Therefore, the door body control device of the above embodiment can accurately control the stop position of the door body, so that the door body stops at The target opening angle can not only completely release the heat in the dishwasher, but also improve the washing performance of the dishwasher and greatly improve the user experience.

According to an embodiment of the present application, the detector 200 includes an angle detector 201, and the door body M includes: an inner wall and an outer wall, and a door body space formed between the inner wall and the outer wall, wherein the angle detector is located in the space of the door body M and is attached Attached to the outer wall.

For example, as shown in FIG. 4, the angle detector 201 may be disposed at a position L length from the bottom of the door body M, and the surface of the angle detector 201 is as close as possible to the outer wall. When the door body M is opened, At this time, the angle detector 201 will output different detection values according to the rotation angle of the door body. When the door body M is rotated to the position shown in FIG. 4, the angle detector 201 detects that the horizontal angle is a, then the door body M actual rotation angle b = 90 ° -a. As a result, the rotation angle of the door body M can be detected quickly and accurately through the angle detector 201. Compared to the detection of different positions through multiple limit switches, the connection line speed is reduced, the cost is reduced, and the reliability is high. .

According to an embodiment of the present application, as shown in FIG. 5, the dishwasher has a main control board, the main control board has a turbidity detection circuit 10 and a turbidity detection interface, and the angle detector 201 reuses the turbidity detection circuit 10 and turbidity The degree detection interface is connected to the controller 300.

Specifically, as shown in FIG. 5, the turbidity detection circuit 10 may include a first capacitor C1, a first resistor R1, and a second resistor R2. One end of the first capacitor C1 is connected to one end of the first resistor R1 and has a first node. The first node is connected to the angle detector 100 as a turbidity detection interface, and the other end of the first capacitor C1 is grounded; the second resistor R2 One end of is connected to the other end of the first resistor R1 and has a second node, the second node is connected to the controller 300, and the other end of the second resistor R2 is grounded.

When the door is opened, the angle detector 201 outputs a different detection signal, that is, a first voltage signal, according to the rotation angle when the door is opened. The first voltage signal is input to the turbidity detection circuit 10 through the first node. There is a certain relationship between the first voltage signal and the rotation angle when the door is opened. After receiving the first voltage signal, the turbidity detection circuit 10 may output a corresponding second voltage signal from the other end of the first resistor R1 to the controller 300 (such as an MCU), where the second voltage signal and the first voltage signal There is a certain relationship, so there is also a certain relationship between the second voltage signal and the magnitude of the rotation angle when the door is opened. Therefore, when the controller 300 receives the second voltage signal, it can analyze the rotation angle of the door when it is opened, so that it can accurately calculate the angle at which the door is opened, that is, it can accurately obtain the current position of the door. , And then realize automatic control of the dishwasher according to the current position of the door body, and improve the control performance of the dishwasher.

The door control instruction may be a door opening control instruction or a door closing control instruction, wherein the door opening control instruction may include an instruction to control the door body M to open to a certain angle. This application only introduces the door opening control instruction and only one stop angle. The implementation principle of the door closing control instruction is basically the same, and will not be described again.

Specifically, after the dishwasher is powered on, when the user needs to open the door body M, the user makes a preset action at a specified position in front of the dishwasher, such as a preset gesture, and moves the foot according to a preset rule. In this way, the sensor 400 can sense the user's motion and can generate a sensing signal according to the user's motion. Then, the sensor 400 compares the sensing signal with a preset condition comparison table. When the sensing signal meets the preset condition When comparing the preset conditions corresponding to the door opening control instruction in the table, the sensor 400 generates a door opening control instruction and sends the door opening control instruction to the controller 300. When the controller 300 receives the door opening control instruction, it controls the driver 100 to drive the door body M to rotate outward relative to the box body. During the rotation of the door body M, the light sensor detects the distance between itself and the ground or wall in real time, and This distance is sent to the controller 300. The controller 300 calculates the current opening degree of the door body M according to the distance, and further controls the driver 100 to stop when the door body opening degree reaches the stopping angle. At this time, the door body M stops at the stopping angle corresponding to the door opening control command.

In an embodiment of the present application, the sensor 400 is further configured to determine whether the sensing signal meets a preset condition according to a frequency and an amplitude of the sensing signal.

For example, when the frequency of the sensing signal is greater than a first preset frequency and the amplitude of the sensing signal is greater than the first preset amplitude, it is determined that the sensing signal meets a preset condition, and the sensor 400 may The door opening control command is generated, and the controller 300 may control the door body M to stop at the system angle. In this way, the controller 300 can control the door M to be opened according to the action made by the user.

It should be noted that the amplitude of the induction signal is related to the position of the user relative to the dishwasher. The closer the user is to the dishwasher, the larger the amplitude of the induction signal, otherwise, the farther the user is from the dishwasher, the more The smaller the amplitude of the signal.

Specifically, the voltage across the resistor R can be used as the output voltage of the infrared receiving component 412, that is, the induced signal. In this way, when the infrared light emitting diode D1 is turned on to emit infrared light to the preset action area, the infrared receiving diode D2 can receive the reflected infrared light, and the voltage across the resistor R changes with the reflected light, that is, the When receiving the reflected light, the infrared receiving diode D2 is turned off, and the voltage across the resistor R is zero; when receiving the reflected light, the infrared receiving diode D2 is turned on, there is a voltage across the resistor R, and the higher the intensity of the reflected light, it flows out of the photosensitive receiving tube The greater the current at D2, the greater the voltage across resistor R. The control chip 413 may determine whether the voltage across the resistor R meets a preset condition, and generates a gate control instruction when the preset condition is satisfied.
