参照图2所示，本发明的优选的实施方式提供的一种自动开关门冰箱的控制方法，所述控制方法包括如下步骤：Referring to Figure 2, a preferred embodiment of the present invention provides a control method for an automatic door opening and closing refrigerator. The control method includes the following steps:
S1、获取抽屉门的开门指令；S1. Get the instruction to open the drawer door;
S2、判断第一门体是否处于开启状态；S2. Determine whether the first door is open;
S3、当第一门体处于开启状态时，在预设时间Ts内触发开关的触发次数N1达到预设的触发次数Ns后，控制抽屉门打开。S3. When the first door is in the open state, after the number of triggers N1 of the trigger switch reaches the preset number of triggers Ns within the preset time Ts, the drawer door is controlled to open.
本实施例中，所述步骤S2中，冰箱通过门体开关、霍尔开关或者接近开关等传 感器，来对第一门体20进行检测，继而判断第一门体20是处于开启状态还是处于关闭状态。In this embodiment, in step S2, the refrigerator transmits a signal through a door switch, a Hall switch or a proximity switch. The sensor is used to detect the first door body 20 and then determine whether the first door body 20 is in an open state or a closed state.
所述步骤S3中，以预设的时间间隔获取触发开关的触发次数N1。在预设时间Ts内触发开关的触发次数N1具体是指：持续的一段时间Ts内，共计检测到的触发开关的触发次数之和。In the step S3, the number of triggering times N1 of the trigger switch is obtained at a preset time interval. The number of triggering times N1 of the trigger switch within the preset time Ts specifically refers to: the sum of the total number of detected triggering times of the trigger switch within a continuous period of time Ts.
所述步骤S3中，当第一门体20处于打开状态，用户在预设时间Ts内的触发次数N1未达到Ns，此时判断用户没有开门意图，因此控制抽屉门10关闭，避免自动打开抽屉门10造成用户受伤。当第一门体20处于打开状态，且用户仍然需要打开抽屉门10时，只要满足预设时间Ts内对触发开关进行了Ns次触发操作即可，此时判断用户具有开门意图。In step S3, when the first door body 20 is in the open state and the user's trigger number N1 within the preset time Ts has not reached Ns, it is determined that the user has no intention to open the door, so the drawer door 10 is controlled to close to avoid automatically opening the drawer. Door 10 caused injury to the user. When the first door body 20 is in the open state and the user still needs to open the drawer door 10, as long as the trigger switch is triggered Ns times within the preset time Ts, it is determined that the user has the intention to open the door.
而且，由于在预设时间Ts内获取到的触发开关的触发次数N1，可能是间隔时间相等的多次触发，也可能是间隔时间不等的多次触发，这样一来，只要对预设时间Ts内触发开关的触发总次数进行判断，即可准确地判断用户有无开门意图。Moreover, since the number of triggers N1 of the trigger switch obtained within the preset time Ts may be multiple triggers with equal intervals, or multiple triggers with unequal intervals. In this way, as long as the preset time is By judging the total number of triggering times of the trigger switch in Ts, you can accurately determine whether the user has the intention to open the door.
在获取到第一门体20处于开启状态时，通过检测预定时间Ts内触发开关的触发次数N1来判断用户是否有开门意图，从而避免抽屉门10因为误触而造成的开启，提高了抽屉门10开启时的安全性能。When it is obtained that the first door body 20 is in the open state, it is determined whether the user has the intention to open the door by detecting the number of triggering times N1 of the trigger switch within the predetermined time Ts, thereby preventing the drawer door 10 from being opened due to accidental touch, and improving the efficiency of the drawer door. 10 Safety performance when turned on.
具体的，所述步骤S1中，抽屉门的开门指令具体是指：以预设的时间间隔获取的触发开关的触发信号。本实施例中，所述步骤S1中，第一门体20上的触发开关会以预设的时间间隔获取用户的触发操作，当用户对触发开关产生触发信号后，整个控制程序即可开始运行。其中，由于触发开关采用的是相对灵敏的触摸开关或者敲击开关，因此用户不小心的触摸，或者对间室进行翻动而产生的振动，都会对触发开关造成触发信号，所以本实施例的控制程序更适用于避免防误触而产生的自动开门。Specifically, in step S1, the instruction to open the drawer door specifically refers to: the trigger signal of the trigger switch obtained at a preset time interval. In this embodiment, in the step S1, the trigger switch on the first door 20 will obtain the user's trigger operation at a preset time interval. When the user generates a trigger signal to the trigger switch, the entire control program can start running. . Among them, since the trigger switch uses a relatively sensitive touch switch or knock switch, the user's careless touch or vibration caused by flipping the chamber will cause a trigger signal to the trigger switch. Therefore, the control of this embodiment The program is more suitable for preventing automatic door opening caused by accidental touch.
配合参照图3所示，进一步的，所述控制方法还包括步骤S4：当第一门体处于关闭状态时，控制抽屉门以预设的速度Va打开。本实施例中，预设的速度Va是抽屉门10所能达到的最大开启速度。所述步骤S4中，当第一门体20处于关闭状态时，控制抽屉门10打开，不影响用户对冷冻室进行存放或者取用操作。并且，控制抽屉门10以最大速度Va打开，能够缩短抽屉门10的开门时间，从而缩短用户对冷冻室的取放操作时间。Referring to FIG. 3 , further, the control method further includes step S4: when the first door body is in a closed state, control the drawer door to open at a preset speed Va. In this embodiment, the preset speed Va is the maximum opening speed that the drawer door 10 can achieve. In the step S4, when the first door body 20 is in a closed state, the drawer door 10 is controlled to open, which does not affect the user's storage or retrieval operation of the freezer compartment. In addition, controlling the drawer door 10 to open at the maximum speed Va can shorten the opening time of the drawer door 10, thereby shortening the user's time of picking and placing the freezer compartment.
进一步的，所述步骤S3中，在触发次数N1达到预设的触发次数Ns后，控制抽屉门以预设的速度Vb打开，其中Vb＜Va。 Further, in step S3, after the number of triggers N1 reaches the preset number of triggers Ns, the drawer door is controlled to open at a preset speed Vb, where Vb<Va.
本实施例中，所述步骤S3中，在第一门体20打开时，用户仍然需要对冷冻室进行存放或者取用操作，此时的抽屉门10以小于最大速度Va打开，即以预设的速度Vb打开。这样一来，在第一门体20打开时，即使用户因为误触自动打开了抽屉门10，由于抽屉门10的开门速度较低，抽屉门10对用户造成的伤害降到了最低，而且还给了用户更多的反应时间，以便用户对突然打开的抽屉门10作出避让反应。In this embodiment, in step S3, when the first door 20 is opened, the user still needs to store or access the freezer compartment. At this time, the drawer door 10 is opened at a speed less than the maximum speed Va, that is, at a preset speed. The speed Vb opens. In this way, when the first door body 20 is opened, even if the user automatically opens the drawer door 10 due to a mistaken touch, due to the low opening speed of the drawer door 10, the damage caused by the drawer door 10 to the user is minimized, and the user is also This gives the user more reaction time so that the user can make an avoidance response to the suddenly opened drawer door 10.
配合参照图4所示，进一步的，所述步骤S3中，获取到抽屉门以预设的速度Vb开启至设定的行程D1后，增大抽屉门的开门速度，并在抽屉门开启至设定的行程Ds后停止开门，其中D1＜Ds。Referring to Figure 4, further, in step S3, after it is obtained that the drawer door opens to the set stroke D1 at the preset speed Vb, the opening speed of the drawer door is increased, and when the drawer door opens to the set stroke The door will stop opening after a certain stroke Ds, where D1＜Ds.
本实施例中，所述步骤S3中，在第一门体20打开时，由于抽屉门10以预设的速度Vb移动了行程D1，这段时间给足了用户作出避让反应。在抽屉门10开启至设定的行程D1后，增大抽屉门10的开门速度，能够缩短抽屉门10的开门时间，从而缩短用户对冷冻室的取放操作时间。In this embodiment, in step S3, when the first door body 20 is opened, since the drawer door 10 moves the distance D1 at the preset speed Vb, this period of time gives the user enough time to make an avoidance reaction. After the drawer door 10 is opened to the set stroke D1, increasing the opening speed of the drawer door 10 can shorten the opening time of the drawer door 10, thereby shortening the user's access time to the freezer compartment.
进一步的，所述步骤S3中，在抽屉门开启至设定的行程D1后，控制抽屉门以预设的速度Va打开，并在抽屉门开启至设定的行程Ds后停止开门。本实施例中，行程Ds为抽屉门10的最大行程。所述步骤S3中，在抽屉门10开启的行程达到D1后，控制抽屉门10以最大速度Va运行，并运行至最大行程Ds后停止开门，进一步缩短抽屉门10的开门时间。由于步骤S3采用了与步骤S4中相同的抽屉门10开启速度Va，而无需设置新的开启速度，能够简化控制程序。Further, in step S3, after the drawer door is opened to the set stroke D1, the drawer door is controlled to open at a preset speed Va, and after the drawer door is opened to the set stroke Ds, the door is stopped. In this embodiment, the stroke Ds is the maximum stroke of the drawer door 10 . In step S3, after the opening stroke of the drawer door 10 reaches D1, the drawer door 10 is controlled to run at the maximum speed Va, and stops opening the door after running to the maximum stroke Ds, further shortening the opening time of the drawer door 10. Since step S3 adopts the same opening speed Va of the drawer door 10 as in step S4, there is no need to set a new opening speed, and the control program can be simplified.
具体的，所述步骤S3中，获取到抽屉门移动设定的行程D1后，降低驱动电机的转速。本实施例中，所述步骤S3中，由于抽屉门10利用驱动电机进行驱动，因此通过改变驱动电机的转速来调整抽屉门10的平移速度，实现方式较为简单且便于控制，降低了冰箱的控制和制造成本。Specifically, in step S3, after obtaining the stroke D1 set by the movement of the drawer door, the rotation speed of the driving motor is reduced. In this embodiment, in step S3, since the drawer door 10 is driven by a driving motor, the translation speed of the drawer door 10 is adjusted by changing the rotation speed of the driving motor. The implementation method is relatively simple and easy to control, and reduces the control of the refrigerator. and manufacturing costs.
具体的，所述步骤S3中，在触发次数N1达到预设的触发次数Ns后，打开驱动电机，并在抽屉门移动设定的行程Ds后关闭驱动电机。本实施例中，所述步骤S3中，通过控制驱动电机的打开或者关闭，来实现抽屉门10的开门动作或者停止开门动作，实现方式较为简单且便于控制，降低了冰箱的控制和制造成本。Specifically, in step S3, after the number of triggers N1 reaches the preset number of triggers Ns, the drive motor is turned on, and the drive motor is turned off after the drawer door moves the set stroke Ds. In this embodiment, in step S3, the opening or closing of the drive motor is controlled to realize or stop the opening of the drawer door 10. The implementation method is relatively simple and easy to control, which reduces the control and manufacturing costs of the refrigerator.
具体的，所述步骤S4中，当第一门体处于关闭状态时，控制驱动电机以恒定转速运行，并在抽屉门移动设定的行程Ds后关闭驱动电机。Specifically, in step S4, when the first door body is in a closed state, the drive motor is controlled to run at a constant speed, and the drive motor is turned off after the drawer door moves a set stroke Ds.
本实施例中，所述步骤S4中，同样通过控制驱动电机的打开或者关闭，来实现抽屉门10的开门动作或者停止开门动作。利用驱动电机以恒定速度转动，来带动抽屉门10以恒定速度平移，从而减小抽屉门10平移时对冰箱箱体产出的晃动。由于 步骤S4中采用了与步骤S3中相同的行程Ds，即抽屉门10的最大行程，而无需设置新的行程，从而简化控制程序。In this embodiment, in step S4, the opening or closing of the drive motor is also controlled to realize or stop the opening action of the drawer door 10. The drive motor is used to rotate at a constant speed to drive the drawer door 10 to translate at a constant speed, thereby reducing the shaking of the refrigerator box when the drawer door 10 is translated. because In step S4, the same stroke Ds as in step S3, that is, the maximum stroke of the drawer door 10, is used without setting a new stroke, thereby simplifying the control program.
进一步的，所述步骤S2中，以预设的时间间隔获取第一门体或第二门体是否处于开启状态。本实施例中，当用户打开第一门体20和/或第二门体30时，都会对抽屉门10的开启进行限制，避免产生误触开门的情况，从而更适用于多间室的冰箱，例如法式冰箱。Further, in step S2, whether the first door or the second door is in an open state is obtained at a preset time interval. In this embodiment, when the user opens the first door 20 and/or the second door 30, the opening of the drawer door 10 will be restricted to avoid accidentally opening the door, thus making it more suitable for refrigerators with multiple compartments. , such as a French style refrigerator.
