With the progress of technology, the level of intelligence of refrigerators is higher and higher. Some refrigerators are provided with an electric door opening device. When a user wants to open the door, corresponding door opening operation is carried out on the touch screen on the surface of the door body, and the electric door opening device can be started to operate to forcibly open the door body.

However, the existing refrigerator with the automatic door opening has some defects which greatly affect the user experience. For example, when a user performs a door opening touch operation, it is not known whether the operation is successful, and the user often needs to click and slide around the screen until the door is opened. In addition, sometimes a user may touch the touch screen unintentionally when wiping the door body, and sometimes the door body may be opened by mistake.

The invention aims to overcome at least one defect in the prior art and provide the refrigerator which has stronger man-machine interaction and higher user experience and can automatically open the door.

It is a further object of the present invention to avoid the user from repeatedly opening the door multiple times, either intentionally or unintentionally.

The invention further aims to prevent the door body from being opened by mistake.

In particular, the present invention provides a refrigerator body comprising: a box body; the door body is arranged on the box body; the door opening device is used for forcibly opening the door body; the vibration device is arranged on the door body and used for generating vibration; an operation detection device configured to receive a user operation applied thereto and generate a door opening signal when it is determined that the user operation belongs to a valid door opening operation; when the user operation is judged to belong to the misoperation, controlling the vibration device to generate misoperation reminding vibration; and the control device is configured to control the door opening device to open the door body when receiving the door opening signal.

Optionally, the control device controls the vibration device to generate door opening reminding vibration when judging that the user operation is effective door opening operation; and the vibration effect of the door opening reminding vibration is different from that of the misoperation reminding vibration.

Alternatively, the duration of the door opening warning vibration is longer than the duration of the erroneous operation warning vibration.

Optionally, the operation detection device includes a touch screen for receiving a touch operation, and the touch screen has an effective sensing area and a missensing area surrounding the effective sensing area; and the control device is configured to judge the user operation of which the effective induction area is triggered firstly or triggered only as the effective door opening operation, and judge the user operation of which the false induction area is triggered firstly or triggered only as the false operation.

Alternatively, the control device is configured to determine that the operations sliding from the erroneous sensing area to the effective sensing area are all erroneous operations.

Optionally, the door body comprises a square frame which is opened front and back, and a front panel and a door liner which are respectively arranged at the front opening and the back opening of the frame; the touch screen is attached to the inner surface of the front panel to receive user operation performed on the outer surface of the front panel; and the vibrating device is abutted against the inner surface of the front panel.

Optionally, the refrigerator further comprises: the embedded box is in an embedded box shape and covers and buckles the inner surface of the front panel; and the operation detection device is fixed in the embedded box.

Optionally, the vibrating device is a motor.

The refrigerator has an automatic door opening function. When the operation detection device receives the misoperation of the user, the vibration device generates misoperation reminding vibration to remind the user to stop operating in time, so that the user is prevented from repeating multiple times of misoperation. When the operation detection device receives effective door opening operation of a user, the vibration device generates door opening reminding vibration to remind the user that the door opening operation is successful, continuous operation is not needed, and the user can wait for the door to be automatically opened. This prevents the user from having completed the correct operation, but repeating the operation a number of times without having effective feedback.

Detailed Description

Fig. 1 is a schematic block diagram of a refrigerator according to one embodiment of the present invention. As shown in fig. 1, a refrigerator according to an embodiment of the present invention may generally include a cabinet 900, a door 100, an operation detection device 200, a door opening device 700, a vibration device 300, and a control device 600.

The case 900 is to define a storage compartment having an opening at one side thereof so that a user can store articles. The door 100 is mounted to the cabinet 900 to open and close the storage compartment. For example, the door 100 may be rotatably mounted to the cabinet 900. The door opening device 700 is used to forcibly open the door body 100. The door opening device 700 may be mounted to the cabinet 900. The vibration device 300 is mounted to the door body 100 to generate vibration. The operation detection device 200 is configured to receive a user operation applied thereto and to make a judgment on the user operation. When the user operation is judged to belong to the effective door opening operation, a door opening signal is generated; when it is determined that the user operation belongs to the erroneous operation, the vibration device 300 is controlled to generate the "erroneous operation reminding vibration". The control device 600 is configured to control the door opening device 700 to open the door 100 when receiving the door opening signal.

For example, the operation detection apparatus 200 may include a touch screen 210, and the user operation is a click or slide operation applied by a human body on the touch screen 210. The touch screen 210 may be disposed on the cabinet 900, or on the door 100, preferably on the door 100. The operation detection device 200 may also include other types of sensing devices to recognize the user's intention to open the door, such as a gesture or voice. The door opening device 700 may include a motor and a transmission mechanism, and after the motor is powered on and rotates, power is transmitted to the door 100 through the transmission mechanism, so as to force the door 100 to open. For example, the door body 100 may be fully opened; alternatively, only a small angle (e.g., 30 °) may be opened, followed by manual opening by the user. The vibration device 300 may be a motor, and the motor will vibrate during the rotation process to drive the mounting carrier to vibrate. The motor can generate sound while vibrating, and the function of prompting the user is also achieved.

The refrigerator according to the embodiment of the present invention realizes an automatic door opening function using the operation detecting device 200, the control device 600, and the door opening device 700. In addition, when the operation detection device 200 receives the misoperation of the user, the vibration device 300 generates the misoperation reminding vibration to remind the user to stop operating in time, so that the user is prevented from repeating multiple times of misoperation. For example, when the user accidentally touches the sensing area of the operation detection device 200 and accidentally performs an erroneous operation without opening the door, the user feels vibration (or also hears sound of the vibration), and stops the operation, and the user is away from the sensing area of the operation detection device 200 to prevent the door 100 from being opened.

Further, the vibration device 300 may be used to prompt a proper door opening operation. That is, the operation detection device 200 controls the vibration device 300 to generate the "door opening warning vibration" when it is determined that the user operation is the valid door opening operation. Of course, the vibration effect of the door opening reminding vibration and the misoperation reminding vibration needs to be set to be different. The different vibration effects may be different vibration time, different vibration intensity, or the like. For example, the duration of the door opening warning vibration may be made longer than the duration of the erroneous operation warning vibration. If the duration time of the door opening reminding vibration is 2 seconds, the duration time of the misoperation reminding vibration is 0.4 seconds. The door opening reminding vibration of the vibration device 300 can remind the user that the door opening operation is successful, the operation does not need to be continued, and the user waits for the automatic opening of the door body 100. Thus, the user can be prevented from completing correct operation, and the operation is repeated for a plurality of times because no effective feedback is received.

In a word, the embodiment of the invention has the advantages that the man-machine interaction inductance of the refrigerator is stronger and the user experience is higher through the misoperation reminding vibration and the door opening reminding vibration.

Fig. 2 is a schematic structural view of a door 100 of a refrigerator according to an embodiment of the present invention; fig. 3 is a schematic diagram of a sensing area of the touch screen 210 in fig. 2.

As shown in fig. 2 and 3, the operation detection device 200 includes a touch screen 210 for receiving a touch operation, which has an effective sensing area and a false sensing area surrounding the effective sensing area. For example, the rectangular effective sensing area enclosed by the box C1 is set. The region between block C2 and block C1 is set as a misinduction region. The operation detection device 200 is configured to determine that a user operation in which the effective sensing area is first triggered or uniquely triggered is an effective door opening operation, and determine that a user operation in which the erroneous sensing area is first triggered or uniquely triggered is an erroneous operation. For example, an operation in which the user clicks or slides only in the valid sensing area will be determined as a valid door opening operation. In addition, when the user operates in the effective induction area and slides to the error induction area, the operation still belongs to the effective operation. The click or slide operation by the user only in the false sensing area is judged as a false operation. For example, the operation (for example, indicated by an arrow in fig. 3) that slides from the erroneous sensing area to the effective sensing area is determined as the erroneous operation. Therefore, when a user wipes the refrigerator door body 100, the sliding operation that the user firstly passes through the error induction area from far to near and then slides to the effective induction area is excluded from the effective operation, and the door body 100 is prevented from being opened by mistake when the user wipes the door body 100.

The prior art sets up a button usually, and when the human body touched the region outside the start key by mistake, the door body can not open, also can not any warning. And once the user mistakenly touches the start key area, the door body is opened. This structure is very likely to cause malfunction.

In the embodiment of the invention, the error induction area is particularly arranged on the outer ring of the effective induction area to serve as a buffer zone, and when a human body enters the error induction area, the vibration prompt is sent out, so that the human body can be completely prevented from further entering the effective induction area. This greatly reduces the possibility of occurrence of malfunction.

A door opening button (i.e., the "OPEN" button in fig. 3) may be provided in the active sensing area, so that, more significantly, the operation of clicking the door opening button is regarded as an active door opening operation.

Of course, when receiving the user operation, the touch screen 210 may also emit light or sound to prompt the user whether the operation belongs to an effective door opening operation or a wrong operation. However, the vibration reminding directly acts on the human body, so that people feel more direct, and the prompting function of the vibration reminding is stronger than that of light and sound.

FIG. 4 is an exploded view of the door body 100 of FIG. 2; fig. 5 is an enlarged view of a portion of the operation detecting device 200, the vibrating device 300, and the cartridge 500 in fig. 3.

As shown in fig. 4 and 5, the door body 100 may include a square-shaped frame 120 opened front and rear, and a front panel 110 and a door liner 130 respectively installed at front and rear openings of the frame 120. The surface of the front panel 110 facing the door liner 130 is an inner surface, and the surface facing the outside is an outer surface. The spaced area between the front panel 110 and the door liner 130 is used to fill the foam layer. The frame 120 includes four portions, i.e., upper, lower, left, and right portions, for forming the top, bottom, left, and right appearances of the door body 100. The front panel 110 serves to constitute a front appearance of the door body 100, and the door liner 130 serves to constitute a rear (inner) appearance of the door body 100. The touch screen 210 is attached to the inner surface of the front panel 110 to receive user operations performed on the outer surface of the front panel 110. The front panel 110 may be a glass panel to facilitate light emitted through the touch screen 210. The vibration device 300 is attached to the inner surface of the front panel 110 to transmit vibration to the human body through the front panel 110.

The refrigerator may include a built-in box 500. The embedded box 500 is in a cover shell shape, and covers and buckles the inner surface of the front panel 110 to define an accommodating space together with the inner surface of the front panel 110. The operation detection device 200 is fixed in the embedded box 500, and the outer side of the embedded box 500 is filled with a foaming layer. The installation of the embedded box 500 can prevent the operation detection device 200 from being affected by the foaming layer.

The vibration device 300 may be mounted at an end of the operation detection device 200 and pressed against the inner surface of the front panel 110 by the operation detection device 200. Since the end of the operation detection device 200 is not likely to be deformed by swelling, it can be always attached to the front panel 110. The vibration device 300 is attached to the end of the operation detection device 200, and can be always attached to the front panel 110, which is more advantageous for transmitting vibration. The operation detection device 200 is provided with a mounting cavity 201 for accommodating the vibration device 300.

Further, the vibration device 300 may be installed near the door opening button of the touch screen 210, as shown in fig. 4 and 5, so that the vibration device 300 is located right on top of the door opening button, and thus the user can sense the vibration of the vibration device 300 in a closer distance when pressing the door opening button.

The pre-buried box 500 can be adhered to the inner surface of the front panel 110, and a convex rib 510 is formed on the surface of the pre-buried box 500 for adhering to the front panel 110, so that a gap for accommodating the adhesive is formed between the surface and the inner surface of the front panel 110, as shown in fig. 5. Therefore, the thickness of the bonding material of each bonding point of the embedded box 500 and the front panel 110 is more uniform, and the situation that the embedded box 500 is not firm due to the fact that the local thickness is thinner is avoided.

Fig. 6 is a bottom view of the door body 100 shown in fig. 2. As shown in fig. 6, the bottom end of the embedded box 500 is close to the bottom edge of the frame 120, and the accommodating space defined by the embedded box and the front panel 110 is open downward. Further, the bottom side of the frame 120 is provided with an insertion opening 121 so that the operation detection device 200 can be inserted into or extend out of the embedded box 500 from the insertion opening 121, so that a maintenance worker can maintain or replace the operation detection device 200. A cover 123 is attached to the insertion opening 121, and the cover 123 is fastened to the bezel 120 by screws.

Fig. 7 is a schematic diagram of a rear structure of the operation detection device 200 shown in fig. 5. As shown in fig. 7, at least one elastic piece 230 is formed on the operation detection device 200. For example, the elastic sheet 230 abuts against the inner surface of the pre-embedded box 500 to generate an elastic pre-tightening force for urging the operation detection device 200 to cling to the front panel 110. Therefore, the touch screen 210 can be in closer contact with the front panel 110, and the touch transmission effect can be ensured. Meanwhile, the vibration device 300 is also conveniently pressed on the front panel 110, thereby ensuring the vibration transmission effect. In fig. 7, it is preferable that the plurality of resilient pieces 230 are arranged in the vertical direction so that the operation detection device 200 is pressed against the front panel 110 at all positions.

Thus, it should be appreciated by those skilled in the art that while a number of exemplary embodiments of the invention have been illustrated and described in detail herein, many other variations or modifications consistent with the principles of the invention may be directly determined or derived from the disclosure of the present invention without departing from the spirit and scope of the invention. Accordingly, the scope of the invention should be understood and interpreted to cover all such other variations or modifications.
