Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be described in further detail below with reference to the accompanying drawings, and it is apparent that the described embodiments are only some embodiments of the present invention, not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
It should be noted that the terms "comprises" and "comprising," and any variations thereof, in the description and claims of the present invention and in the drawings, are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or apparatus that comprises a list of steps or elements is not necessarily limited to those steps or elements expressly listed or inherent to such process, method, article, or apparatus.
It should be noted that the steps illustrated in the flowcharts of the figures may be performed in a computer system such as a set of computer executable instructions, and that although a logical order is illustrated in the flowcharts, in some cases the steps illustrated or described may be performed in an order other than that illustrated herein.
Alternative embodiments of the present invention will be described in detail below with reference to the accompanying drawings.
Referring to fig. 1, the automatic door opening and closing mechanism of a refrigerator includes: an ejector mechanism 10, a rotary mechanism 20, and a controller 30. The controller 30 is electrically connected to the ejector mechanism 10 and the rotary mechanism 20. The door body 40 is pushed open by the ejection mechanism 10 by a small angle, so that the door body 40 is rotated by the rotation mechanism 20 to open or close the door body 40 against the adsorption force generated between the door body 40 and the box body 50 and the pulling force of the door body door closer.
Referring to fig. 2, the rotation mechanism 20 includes: the driving motor 21, the gear set 22 and the output shaft 23 are sequentially connected. The gear set 22 includes a clutch gear 221 (as a clutch), and the clutch gear 221 is capable of communicating with the transmission of the rotation mechanism 20 when the clutch gear 221 is energized, and disconnecting the transmission of the rotation mechanism 20 when the clutch gear 221 is deenergized. When the clutch gear 221 is energized, the rotary mechanism 20 starts to operate, specifically, the driving motor 21 rotates in a currently required direction (the motor rotates in the opposite direction when the door is opened and closed), and the output shaft 23 generates a door opening torque through the transmission of the gear set 22, so as to open or close the door body 40. When the clutch gear 221 is disconnected, the rotation mechanism 20 does not operate. The number of gears in the gear set 22 may be adjusted according to actual requirements (e.g., different weight or size doors, or different door opening speed requirements), thereby adjusting the gear ratio, which corresponds to different output speeds and output torques.
Fig. 3 is a flowchart of a method for controlling an automatic door opening and closing of a refrigerator according to an embodiment of the present invention, as shown in fig. 3, the method includes the following steps:
s301, acquiring the actual weight of the refrigerator door.
S302, adjusting a current threshold according to the actual weight.
And S303, stopping the door opening and closing action when the actual current of the rotating mechanism is continuously preset for a time longer than the current threshold value.
The weight of the refrigerator door body affects the force required to open the door body, and when the weight of the door body increases, the torque required for the rotation of the door body increases, and the larger the current required for the rotating mechanism. That is, the current of the rotation mechanism increases with the increase of the door body resistance. The actual current of the rotation mechanism means the current of the driving motor in the rotation mechanism, and can be detected by a current sensor.
For example, when the change of the actual weight of the refrigerator door body is detected, the primary current threshold value can be adjusted to ensure the timely update of the current threshold value, so that the refrigerator door can be controlled to be automatically opened and closed better, and accidental injury or false touch can be prevented.
The preset time can be set according to experimental tests, the value range of the preset time can be more than or equal to 0.5 seconds, and the preset time is preferably set to 0.5 seconds.
When the actual current of the rotating mechanism is continuously preset for a time longer than the current threshold, the rotating mechanism indicates that resistance is met when the door is automatically opened and closed, the function of stopping suddenly when the door is blocked is triggered, and the current door opening and closing action is stopped. By setting the preset time, the influence (such as motor current fluctuation) caused by accidental errors can be eliminated, misjudgment is prevented, and whether the automatic door opening and closing encounters resistance is judged more accurately.
According to the embodiment, the current threshold value of stopping suddenly and stopping suddenly is timely adjusted according to the actual weight of the refrigerator door body, when the actual current of the rotating mechanism is continuously preset for a time longer than the current threshold value, the door opening and closing action is stopped, the door body is guaranteed to stop when encountering very small external force, the function of stopping suddenly and stopping suddenly is optimized, the situation of accidental injury and false touch is not generated, the use experience of a user is improved, and the problem that the automatic opening and closing of the door of the refrigerator in the prior art easily causes accidental injury or false touch is solved.
Adjusting a current threshold according to the actual weight, comprising: calculating a current threshold corresponding to the actual weight according to the relation between the preset door weight and the current threshold; and setting the calculated current threshold as the current threshold. According to the embodiment, the current threshold is adjusted according to the relation between the preset weight of the door body and the current threshold, so that the reasonable and reliable current threshold can be ensured.
Specifically, the current threshold corresponding to the actual weight may be calculated using the following formula:
wherein G represents the actual weight of the door body, I represents the current threshold corresponding to the actual weight G of the door body, G 0 Indicating the minimum weight of the door body, I 0 Representing the minimum weight G 0 Corresponding current threshold, G M Indicating the maximum weight of the door body, I M Representing maximum weight G M A corresponding current threshold.
The minimum weight of the door body refers to the weight of the door body when no article is placed thereon, i.e., the initial weight of the door body, or the weight of the door called empty door. The maximum weight of the door body refers to the weight of the door body when the door body is full of articles according to the maximum bearing capacity. Maximum current threshold I M And a minimum current threshold I 0 The floating range of the current threshold is formed by testing.
The calculated current threshold corresponding to the actual weight of the door body must be at (I 0 ，I M ) Within the range. The current threshold is linearly and positively correlated with the door weight, illustratively, the door weight is taken as the abscissa, the current threshold is taken as the ordinate, a coordinate system is established, and the current threshold is taken as the ordinate, the current threshold is calculated according to the coordinate (G 0 ，I 0 ) And (G) M ，I M ) A straight line can be drawn, and the coordinates of any point on the straight line can be obtained, namelyAnd taking a current threshold value corresponding to the weight of any door body.
The current threshold corresponding to the weight of any door body can be accurately and reliably calculated through the formula.
Specifically, obtain the actual weight of refrigerator door, include: acquiring the weight of articles placed in each bottle frame on the door body; and obtaining the actual weight according to the weight of the articles placed in each bottle frame. Initial weight of door body (i.e. minimum weight G 0 ) Is fixed and known, and the actual weight of the door body can be obtained by measuring the weight of the articles placed on the door body.
Referring to fig. 4, at least one bottle frame 41 is mounted on the door body 40, and since the overall weight is increased mainly by the weight of the articles placed in the bottle frame 41 after the door body 40 is manufactured, the actual weight of the door body can be obtained by measuring the weight of the articles in the bottle frame 41, and a pressure sensing plate 42 is mounted in the bottle frame 41, and a pressure sensor is mounted in the pressure sensing plate 42, so that the weight of the placed articles can be detected.
Referring to fig. 2, stopping the door opening and closing action includes: the control clutch 221 is de-energized, and the drive motor 21 is controlled to brake.
After stopping the door opening and closing action, further comprising: if no door opening and closing operation is detected within the preset time period, the driving motor 21 is controlled to rotate in the opposite direction to the direction before the door opening and closing operation is stopped until the door body is completely closed or completely opened. The preset duration may be set according to practical situations, for example, set to 60 seconds. Therefore, the door body can be controlled to act in time, and damage is avoided.
For example, in the automatic door closing process, if resistance (such as user interference) or obstacle is encountered, the actual current of the rotating mechanism is detected to be greater than the current threshold, then the current door closing action is stopped, the braking state is kept for a preset period of time, and if the door opening and closing action is not performed within the preset period of time, the driving motor is controlled to rotate in the opposite direction so as to open the door body.
The method for controlling the automatic opening and closing of the door of the refrigerator will be described with reference to a specific embodiment, however, it should be noted that the specific embodiment is only for better illustrating the present application and is not meant to be unduly limiting. The same or corresponding terms as those of the above embodiments are explained, and the present embodiment will not be repeated.

S508, judging whether the micro switch of the rotating mechanism is triggered, if yes, proceeding to S509, if not, continuing to judge the micro switch. The micro-switch of the rotating mechanism is used for judging whether the door body reaches the maximum angle in the automatic door opening process, namely judging whether the door body is completely opened, specifically, the micro-switch reaches the preset position (namely the micro-switch is triggered), and the door body is considered to be opened to the maximum angle (generally 135 degrees), and the door body is completely opened.
S509, the clutch of the rotating mechanism is powered off, the motor of the rotating mechanism stops running and brakes, and the rotating mechanism stops working. When the clutch is powered off, the door body can rotate freely and is not influenced by motor braking, and the structure is prevented from being locked.
S510, ending automatic door opening.
S511, judging whether the current position of the door body is in a fully opened state, if so, entering S512, and if not, entering S505 to continue opening the door.
