Detailed Description
The embodiment of the invention implements the refrigeration equipment as a side-by-side combination refrigerator. The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 1, a refrigerator according to an embodiment of the present invention is configured as a side-by-side refrigerator having three storage compartments and independently cooling each. The refrigerator 100 includes a freezing compartment and a refrigerating compartment which are arranged in parallel, and a freezing door 101 and a refrigerating door 102 which close the freezing compartment and the refrigerating compartment, respectively. The following description will be made of how the refrigerator door opening and closing detection is performed by taking a refrigerating compartment as an example. A Hall sensing switch 1 for sensing whether the refrigerating door 102 is opened or not is arranged in the upper edge of the outer side of the refrigerating chamber liner, and a magnet 2 is arranged on the upper edge of the inner side of the refrigerating door 102; the Hall induction switch 1 and the magnet 2 are arranged at corresponding positions. A radar sensing device 3 for sensing whether a person exists within a predetermined range in front of the refrigerator and a movement tendency of the person and an alarm device 4 for giving an alarm are also provided at an upper edge of an outer side of the inner container of the refrigerating chamber. Referring to fig. 2, the hall sensor switch 1, the radar sensor 3, and the alarm device 4 are respectively connected to the refrigerator controller 5 in a communication manner.
When the refrigerating door 102 is closed, the distance between the Hall sensing switch 1 and the magnet 2 is very short, the attraction force of the magnet 2 is very large, and the Hall sensing switch 1 is in a conducting state, so that a signal indicating that the door is closed is sent to the refrigerator control device 5; when the refrigerating door 102 is opened, the distance between the hall sensor switch 1 and the magnet 2 is increased, the attraction force of the magnet 2 is reduced to be small, and the hall sensor switch 1 is in an off state, thereby transmitting a signal indicating that the door is opened to the refrigerator control device 5. When the state where the refrigerating door 102 is opened continues for more than a certain time, for example, 1 to 2 minutes, the refrigerator control device 5 controls the alarm device 4 to issue an alarm to prompt the user to close the refrigerating door 102.
However, if the alarm sound is generated by the refrigerator when the user opens the refrigerator door to arrange the storage room or store articles for a certain period of time, the user will be unnecessarily disturbed, and the user must close the refrigerator door to release the alarm and then open the door again, which causes unnecessary troubles.
In order to solve the interference of unnecessary alarms, the invention provides an improved control method of a refrigerator, and particularly improves the control rule of an alarm device in the working process of the refrigerator so as to improve the experience of a user using the refrigerator and reduce energy consumption.
In one embodiment, an improved control method of a refrigerator is shown in fig. 3, and is described below by specific steps.
Step SO1, refrigerator operation.
Step S02, detecting whether the refrigerator door is opened for more than a first preset time.
When the refrigerator door is opened, the hall sensor switch deaf sends a door opening signal to the refrigerator control device, and the refrigerator control device starts timing to determine whether the door opening state exceeds a first preset time, such as 1-2 minutes. If the door open state does not exceed the first preset time, the judgment is continued. If the door open state exceeds the first preset time, the process proceeds directly to step SO 3.
And step SO3, detecting whether a person is in a range of a preset distance from the refrigerator.
The radar sensing device detects whether a person exists in a range of a preset distance from the refrigerator and the movement trend of the person, and feeds back a detection signal to the refrigerator control device. When the radar sensing device detects that no person is in the range of the preset distance from the refrigerator, the step S06 is directly skipped, and the refrigerator control device controls the alarm device to give an alarm to prompt the user to close the refrigerator door.
When the radar sensing device detects that a person is within a predetermined distance from the refrigerator, the operation proceeds to step SO 4.
In step S04, the alarm device delays issuing the alarm.
If people are detected near the refrigerator, the refrigerator control device can control the alarm device not to send out an alarm or send out the alarm after a period of time.
And step S05, postponing whether the alarm exceeds a preset time.
One way to determine whether the delayed issuance of an alarm exceeds a predetermined time is to issue an alarm when the door is opened for a time greater than a second predetermined time, the second predetermined time including and being greater than the first predetermined time, or continue to delay issuance of an alarm. When the refrigerator door is opened beyond a certain maximum time limit, no matter whether a person is in front of the refrigerator, the alarm sound is sent out to prompt a user to close the refrigerator door, and the situation that the user does not perceive that the refrigerator door is not completely closed is avoided.
Another way to determine whether the delay in issuing the alarm exceeds a preset time is for the alarm device to issue the alarm after waiting a third predetermined time. The third preset time is immediately after the first preset time. When a person is detected in front of the refrigerator, the user can postpone a certain reasonable time to send out an alarm, and the user can use the refrigerator within the postponed reasonable time without being interfered by the alarm sound.
In step S06, the alarm device issues an alarm.
The previous description of the disclosed embodiments is provided to enable any person skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the generic principles defined herein may be applied to other embodiments without departing from the spirit or scope of the invention. Thus, the present invention is not intended to be limited to the embodiments shown herein but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
