Description

Control method of food storage

The present invention relates to a food storage control method, and in particular, a first sensing step of detecting the opening and closing of the door of the food storage, a second sensing step of detecting the human body when the door is opened, and the human body It relates to a food storage control method comprising a control step of controlling the opening notification of the door when detected.

In general, a refrigerator is a device for keeping food at a low temperature. The refrigerator includes a main body in which a storage compartment is formed and a door for selectively opening and closing the storage compartment.

The storage compartment may be divided into a freezer compartment and a refrigerator compartment, and the refrigerator compartment and the freezer compartment may be selectively opened and closed by respective doors.

In addition, the main body is provided with a refrigeration system for maintaining the storage compartment at a low temperature. The freezing compartment and the refrigerating compartment may be maintained at a reference temperature by the refrigeration system.

Here, if the user does not close the door inadvertently, the air in the air meets the air of the outside air and the temperature rises, which causes a problem that the storage state of the food stored in the inside worsens, unnecessarily freezing system to lower the temperature in the air Since this is working, there is a problem that the power consumption is increased.

Therefore, there is a need for a refrigerator that can be known to the outside by detecting the open state of the door. In particular, although the user has closed the door, the refrigerator is required to notify the outside even when the door is not opened completely, but finely opened.

In order to solve this problem, when the door of the refrigerator is opened, a technique for informing the user that the door is opened through an alarm operation after a predetermined time has been proposed.

However, such a conventional refrigerator operates an alarm when the door is opened for a certain time even when the user cleans the inside of the refrigerator or performs other tasks. For this reason, there is a problem that the alarm is a noise for the user who takes out the kimchi container from the refrigerator and moves it.

Korean Patent Publication No. 2009-0020185

The present invention has been made to solve the above-mentioned problems, when the user is to clean the interior of the food storage or other operations, even if the door of the food storage for a long time to open the door control to control the door open notification to improve user convenience and unnecessary notifications It is an object of the present invention to provide a food storage control method that reduces power consumption.

Food storage control method of the present invention for achieving the above object, the first sensing step of detecting the opening and closing of the door of the food storage, and if the door is opened, the second sensing step of detecting the human body, and And detecting a human body when the human body is detected.

The control step may control not to operate the opening notification of the door, or the control step may control to delay the opening notification of the door, and after the second sensing step, whether the human body sensing duration is longer than a predetermined time. The method may further include determining whether the door is open or not.

According to the food storage control method of the present invention as described above, has the following effects.

A first sensing step of detecting opening and closing of a door of a food storage, a second sensing step of detecting a human body when the door is opened, and a control step of controlling an opening notification of the door when the human body is detected. When the user cleans up the food storage or other work, the door opening notification is controlled even if the door of the food storage is opened for a long time, preventing the door opening notification from acting as a noise to the user, improving user convenience and unnecessary notifications. This eliminates the need for power consumption.

After the second detection step, further comprising the step of determining whether the human body sensing duration is more than a predetermined time, the control step, by controlling the opening notification of the door if the human body sensing duration is more than a predetermined time When the user unintentionally leaves the food storage door open, the user can be instructed to close the door by notifying that the door is opened, thereby inducing the user to save electricity.

1 is a flow chart of a food storage control method according to a preferred embodiment of the present invention.

Hereinafter, a preferred embodiment of the present invention will be described in detail with reference to the accompanying drawings.

For reference, among the configurations of the present invention to be described below, the same configuration as the prior art will be referred to the above-described prior art, and a detailed description thereof will be omitted.

As shown in Figure 1, the food storage control method of the present embodiment, the first detection step (s1) for detecting the opening and closing of the door of the food storage, and the second detection for detecting the human body when the door is opened Step (s5), and the control step (s11) for controlling the opening notification of the door when the human body is detected.

In the first detection step s1, the opening and closing of the door of the food storage is detected through a door opening and closing detection sensor.

When the door is detected to be open (s3), the second detection step (s5) detects whether there is a human body around the food storage.

If it is detected that the door is closed, it returns to the first detection step (s1).

After the second detection step (s5), if the human body is detected (s7) further comprises a step (s9) of determining whether or not the human body detection duration is a predetermined time or more. The predetermined time may be determined by an experiment or the like, and may be 1 minute in this embodiment.

If the human body is not detected, the opening notification operation step (s13) of the door is continued.

The control step s11 controls the opening notification of the door when the human body is detected.

The control step (s11), if the human body sensor duration is more than a predetermined time controls the opening notification of the door.

If the human body sensor duration is not longer than a predetermined time, the opening notification operation step (s13) of the door is continued.

In this way, by controlling the duration of the human body sense, the user does not open the door of the food storage for a separate operation, and when the user unintentionally leaves the food storage door open so that the door is closed by notifying the opening of the door. It can induce users to save electricity.

The control step s11 may control not to operate the opening notification of the door or control to delay the opening notification of the door.

For example, the opening notification time of the door is delayed to be twice the existing notification time (door opening elapsed time), so that the user can be notified that the door is open when the opening time of the door is doubled than the existing notification time. have.

As such, by controlling the opening notification of the door according to whether the human body is detected, even if the user keeps the food storage door open for a long time, the door opening notification is controlled to improve user convenience and unnecessary. No notification is required, which reduces power consumption.

As described above, although described with reference to a preferred embodiment of the present invention, those skilled in the art various modifications or variations of the present invention without departing from the spirit and scope of the invention described in the claims below Can be carried out.
