[0034] Figure 1 FIG. 1 is a flow chart of an automatic door opening control method provided by the present invention. Figure 1 As shown, the automatic door opening control method provided by the present invention includes:

[0035] Step S10, obtaining a knocking signal applied to the door body.

[0036] When the user needs to open the door body 120 , the user knocks on the door body, so that the sensor 130 acquires a knocking signal applied to the door body 120 , and the sensor 130 transmits the acquired knocking signal to the controller 150 .

[0037] Step S20, analyzing the knocking signal, and opening the door according to the knocking signal.

[0038] The controller 150 receives the knock signal transmitted by the sensor 130, and first analyzes and processes the knock signal, such as amplifying the knock signal, removing interference information, and accumulating the number of knocks N applied to the door body 120 within a predetermined period; when the analysis shows that N=1, the lighting device in the compartment corresponding to the door body 120 is opened; when N≥2, the door body 120 of the compartment is opened. The predetermined period can be set between 0s and 5s, and the predetermined period should not be too long, otherwise the risk of misoperation of opening the door body 120 will increase.

[0039] Step S30, identifying the open state of the door.

[0040] Wherein, the step S30 "identifying the opening state of the door body" specifically includes the following steps: Figure 2 As shown,

[0041] S31, identifying the opening state of the door;

[0042] S32, obtaining the door opening time S1;

[0043] S33, determining whether the opening time meets the first threshold S0;

[0044] S34, when the opening time S1 meets the first threshold S0, the state of the door body after opening is identified again;

[0045] Among them, the open state of the door body 120 in the step S20 "analyze the knocking signal and open the door body according to the knocking signal" is set to the first open state, and the open state of the door body 120 when the opening time S1 of the door body 120 meets the first threshold S0 is set to the second open state, and the first threshold S0 is 60s.

[0046] Step S40, judging whether the knocking signal for opening the door is a false operation according to the opening state of the door body,

[0047] Step S50, if it is an erroneous operation, control the door to close, otherwise keep the door open.

[0048] Specifically, the controller 150 compares the second open state with the first open state to determine whether the state of the door body changes after opening; and then determines whether the knocking signal for opening the door is an erroneous operation. If it is an erroneous operation, the controller 150 controls the automatic door opening device 140 and the automatic door closer 160 to close the door body.

[0049] Furthermore, in the aforementioned automatic door opening control method, a microphone can be used to obtain sound waves generated by knocking vibrations applied to the door body 120 and then obtain knocking signals, and a vibration sensor can also be used to obtain knocking signals applied to the door body 120.

[0050] In one embodiment of the present invention, a refrigeration device 100 capable of implementing the above-mentioned automatic door opening control method is also provided. Figure 3 and Figure 4 As shown, the refrigeration device 100 includes a box body 110 having at least one storage chamber 112 and a door body 120 for opening or closing the storage chamber 112, wherein the door body 120 is hingedly mounted to one side of the box body 110. The storage chamber 112 is also provided with a lighting device for illuminating the storage space in the storage chamber 112.

[0051] Furthermore, in order to enable the door body 120 to open the storage room 112 according to the knocking signal applied to the door body 120 by the user, the refrigeration device 100 further includes a sensor 130, an automatic door opening device 140, a controller 150 electrically connected to the sensor 130 and the automatic door opening device 140, and an automatic door closer 160 disposed between the box body 110 and the door body 120. The controller 150 may be disposed on the box body 110.

[0052] In this embodiment, the sensor 130 is disposed on the door body 120 to receive a knock signal applied to the door body 120. Further, in order to improve the accuracy of the sensor 130 in receiving and identifying, the sensor 130 is generally disposed on the front side of the door body 120, and can accurately identify when a user knocks on the door body 120. Optionally, the sensor 130 can be configured as a vibration sensor.

[0053] Further, the automatic door opening device 140 is arranged on the door body 120 or the box body 110. In this embodiment, the automatic door opening device 140 is arranged on the door body 120, and the automatic door opening device 140 includes a driving mechanism 141 and an ejection mechanism 143. Optionally, the automatic door opening device 140 can also be arranged on the upper decorative strip of the door body 120, so as to facilitate the disassembly and assembly of the automatic door opening device 140.

[0054] In this embodiment, a mounting groove for mounting the automatic door opening device 140 is provided on the upper portion of the door body 120, and a buckle structure is formed in the mounting groove. The driving mechanism 141 and the ejection mechanism 143 are respectively snapped into the buckle structure for position limiting, and the output end 1411 of the driving mechanism 141 is transmission-connected with the ejection mechanism 143. Under the action of the driving mechanism 141, the ejection mechanism 143 can slide forward and backward along the thickness direction of the door body 120, thereby completing the opening of the door body 120. In other embodiments of the present invention, the automatic door opening device 140 can also be fixed to the mounting groove on the door body 120 by a saddle clamp structure.

[0055] Further, the door body 120 includes a main door 123 and a sub-door 125. The main door 123 is hingedly mounted to one side of the box body 110 to open or close the storage chamber 112. The sub-door 125 is arranged at the front side of the main door 123 and is also hingedly mounted to the main door 123 or the box body 110. Optionally, the sub-door 125 is hingedly mounted to the main door 123.

[0056] In the prior art, the door of the refrigeration equipment is generally constructed to be opaque, and before opening the door, the user does not know the type and location of the items stored in the storage chamber 112. Therefore, in this embodiment, an opening 1231 is formed on the front side of the main door 123, and a transparent panel is provided at the opening 1231, so that the user can open the secondary door 125 to see the internal space of the storage chamber 112 behind the main door 123, so that the user can accurately understand the location of the items to be taken out, reduce the opening time of the main door 123, and further reduce the loss of coldness in the storage chamber 112.

[0057] In other embodiments of the present invention, a secondary storage room may also be provided at the opening 1231, and items that need to be used frequently may be placed in the secondary storage room. The secondary storage room may be opened or closed by opening the secondary door 125, thereby reducing the loss of cold air in the storage room 112. In addition, providing the secondary storage room on the main door 123 also increases the storage capacity of the refrigeration device 100 and improves space utilization.

[0058] Further, the automatic door opening device 140 is provided on the main door 123. The main door 123 has a front panel 1232 and a rear panel 1233 arranged opposite to each other, and a first slot 1234 and a second slot 1235 respectively arranged on the front panel 1232 and the rear panel 1233. A sliding slot 1236 is also provided between the front panel 1232 and the rear panel 1233, and the ejection mechanism 143 is installed in the sliding slot 1236, thereby limiting the ejection mechanism 143 from sliding forward and backward. And the first slot 1234 and the second slot 1235 are arranged opposite to each other along the sliding direction of the ejection mechanism 143. Under the action of the driving mechanism 141, the ejection mechanism 143 can slide forward and backward along the thickness direction of the main door 123, thereby passing through the first slot 1234 or the second slot 1235 to abut against the secondary door 125 and the box body 110.

[0059] The driving mechanism 141 is configured as a driving motor, and the ejection mechanism 143 includes a gear 1431 and an ejector rod 1432 meshing with the gear 1431. The gear 1431 is in transmission connection with the output end 1411 of the driving motor, and the ejector rod 1432 passes through the first slot 1234 or the second slot 1235 under the action of the driving motor, thereby opening the main door 123 or the auxiliary door 125. Optionally, the ejection mechanism 143 may be configured as a worm gear mechanism.

[0060] In other embodiments of the present invention, the automatic door opening device 140 may also be configured as a screw motor.

[0061] In summary, if Figure 5 As shown, when the main door 123 needs to be opened, the controller 150 controls the drive motor to rotate clockwise, drives the gear 1431 to rotate clockwise, and drives the push rod 1432 to move toward one side of the box body 110, thereby passing through the second slot 1235 to resist the box body 110, thereby realizing the opening of the main door 123; when the door needs to be closed, the controller 150 controls the drive motor to rotate counterclockwise, drives the gear 1431 to rotate counterclockwise, and drives the push rod 1432 to move toward one side of the auxiliary door 125 until the push rod 1432 is completely returned to the main door 123; at the same time, during the counterclockwise rotation of the drive motor, the main door 123 moves toward the box body 110 under the action of the automatic door closer 160 to close the storage room 112.

[0062] like Figure 6 As shown, when the auxiliary door 125 needs to be opened, the controller 150 controls the driving motor to rotate counterclockwise, drives the gear 1431 to rotate counterclockwise, and drives the push rod 1432 to move toward one side of the auxiliary door 125, thereby passing through the first slot 1234 to abut against the auxiliary door 125, thereby realizing the opening of the auxiliary door 125; when the door needs to be closed, the controller 150 controls the driving motor to rotate clockwise, drives the gear 1431 to rotate clockwise, drives the push rod 1432 to move toward one side of the box body 110 until it is completely returned to the main door 123. At the same time, during the clockwise rotation of the driving motor, the auxiliary door 125 moves toward the main door 123 under the action of the automatic door closer 160 to close the auxiliary door 125.

[0063] As a further improvement of an embodiment of the present invention, a first baffle 1433 is further provided on the top rod 1432, and an elastic reset member 1434 is provided between the first baffle 1433 and the front panel 1232 or the rear panel 1233, and the elastic reset member 1434 is sleeved on the outer side of the top rod 1432. Optionally, the elastic reset member 1434 can be set as a spring. When the main door 123 or the auxiliary door 125 is closed, under the action of the elastic reset member 1434, the top rod 1432 returns to the main door. The elastic reset member 1434 is a purely mechanical structure, which can also realize the closure of the main door 123 or the auxiliary door 125 in the event of power failure or drive motor failure, thereby reducing the loss of coldness in the storage chamber 112.

[0064] In this embodiment, when the knocking signal is an erroneous operation, but the controller 150 has opened the door body 120 according to the knocking signal, in order to reduce the loss of cold air in the refrigeration equipment 100, the automatic door closer 160 is arranged between the box body 110 and the main door 123 or the main door 123 and the auxiliary door 125.

[0065] The automatic door closer 160 includes a door closing mechanism 161 disposed between the automatic door opening device 140 and the auxiliary door 125, and the door closing mechanism 161 includes a first magnet 162 disposed at one end of the top rod 1432 facing the auxiliary door 125 and a second magnet 163 disposed on the auxiliary door 125 and corresponding to the first magnet 162. The first magnet 162 and the second magnet 163 attract each other. When the auxiliary door 125 needs to be closed, the first magnet 162 can generate an attractive force on the second magnet 163 on the auxiliary door 125, thereby achieving the closing of the auxiliary door 125.

[0066] In another embodiment of the present invention, a slide column 144 is further provided between the push rod 1432 and the front panel 1232 and the rear panel 1233, and the slide column 144 is connected to the front panel 1232 or the rear panel 1233 through an elastic member. When the push rod 1432 moves toward the box body 110 or the auxiliary door 125, the push rod 1432 first pushes the slide column 144 to move outward, and then the slide column 144 abuts against the box body 110 or the auxiliary door 125, thereby realizing the opening of the main door 123 or the auxiliary door 125.

[0067] In one embodiment of the present invention, an electromagnetic lock 127 is provided on the side of the front panel 1232 of the main door 123 away from the hinge between the main door 123 and the box body 110, and a lock hook 128 matching the electromagnetic lock 127 is provided on the sub-door 125, thereby achieving the closure of the sub-door 125 and the main door 123.

[0068] Furthermore, in order to quickly and accurately identify the opening state of the door body 120, an identification device 170 for identifying the opening state of the door body 120 is also provided on the refrigeration device 100, and the identification device 170 is provided between the cabinet 110 and the main door and between the main door and the auxiliary door. The identification device 170 can be set as a distance measurement module or a Hall element module. The identification device 170 determines the opening state of the main door 123 or the auxiliary door 125 by sensing the position change of the main door 123 or the auxiliary door 125.

[0069] In summary, the beneficial effects of the present invention are as follows: the automatic door opening control method of the present invention realizes the automatic opening of the door body 120 by collecting the knocking signal applied to the door body 120, without the need for complicated actions. In addition, the automatic door opening control method of the present invention also determines whether the knocking signal is a misoperation by comparing the state before and after the door body 120 is opened for a certain period of time; if it is a misoperation, the door body 120 is closed by the automatic door closer 160, thereby avoiding the loss of cold due to misoperation of the refrigeration equipment 100 and improving the user experience. In addition, the present invention realizes the opening of the main door 123 in the refrigeration equipment 100 through the transmission coordination of the ejection mechanism 143 and the drive mechanism 141.
