Description

A cabinet door pusher based on dual switch joint control and control method thereof Technical Field

[0001] The present invention belongs to the technical field of cabinet door pusher control, and in particular, relates to a cabinet door pusher based on dual-switch joint control and a control method thereof. Background Art

[0002] Compared with mechanical rebounders and mechanical switch electric rebounders, the advantage of this design is that there is no need for mechanical pressing of 3mm, and no 3mm gap needs to be reserved between the door and the cabinet; compared with single proximity switch electric door openers, the advantage is that it can improve sensitivity while reducing and eliminating false triggering, thereby improving comfort and reliability.

[0003] For a single proximity switch electric door opener, when a capacitive inductive touch switch or a microwave radar inductive switch is used, the movement of the human hand or body will be detected by the switch after the door is opened, which will cause it to be falsely triggered and pushed out. When the sensitivity is adjusted high, the movement of the cabinet door will be detected by the switch when closing the door, which will falsely trigger repeated door opening. When the sensitivity is adjusted low, the false triggering and repeated door opening will be reduced, but the success rate of door opening will be reduced, and the comfort and reliability of use will be poor.

[0004] In view of this, the present invention is proposed. Summary of the Invention

[0005] In order to solve the above technical problems, the basic concept of the technical solution adopted by the present invention is:

[0006] A cabinet door pusher based on dual-switch joint control, comprising:

[0007] A housing, comprising an upper housing and a lower housing;

[0008] Installation components, used to fix the housing in the cabinet;

[0009] A transmission ejection mechanism is provided in the lower shell for pushing open the cabinet door;

[0010] The dual-switch module includes a first switch and a second switch. The dual switches are electrically connected to a controller, and the controller is electrically connected to the motor.

[0011] As a preferred embodiment of the present invention, the transmission ejection mechanism includes a motor, a reduction gearbox, a screw, a slider and a push rod; wherein, the drive shaft of the motor is dynamically connected to the input shaft of the reduction gearbox, the output shaft of the reduction gearbox is dynamically connected to the screw, the other end of the screw is threadedly screwed through the slider, and the slider is fixed to the push rod.

[0012] As a preferred embodiment of the present invention, two semicircular notches are provided at the ends of the upper shell and the lower shell, respectively for accommodating the second switch and the push rod.

[0013] As a preferred embodiment of the present invention, the dual switch module is arranged on the lower housing.

[0014] As a preferred embodiment of the present invention, the slider is slidably connected to the inner cavity of the shell, and the slider is threadedly screwed onto the screw rod; the second switch adopts either a mechanical door-controlled switch or a non-mechanical door-controlled switch; the first switch adopts a non-mechanical switch that can penetrate a cabinet door made of static insulating material to sense the movement of human hands and body; the mounting assembly includes a base, which is clamped on the lower shell.

[0015] The present invention further discloses a control method for a cabinet door opener based on dual-switch combined control, which is applied to the cabinet door opener based on dual-switch combined control described in any one of the above embodiments, and comprises the following steps:

[0016] S1, the second switch, is a door-controlled switch that only passively detects whether the door is open or closed. It has no door-opening capability and does not directly participate in the door opening. It provides a signal to control the standby time period of the first switch. The implementation method is that the second switch identifies whether the cabinet door is open or closed;

[0017] S2, the first switch, can be activated by touching the static insulating material door panel from outside the door; at this time, the controller will control the motor to rotate forward through the reduction gearbox and the lead screw to drive the push rod through the slider in the lower shell until the push rod extends out of the shell and pushes the cabinet door open. After a certain pause, the push rod automatically retracts and stops at zero position;

[0018] S3. When the second switch detects that the cabinet door is closed, it is set to start the first switch standby after 2 seconds. At this time, the cabinet door is in a static state. The first switch is triggered outside the door and the door opening program runs. After the first switch is triggered, the first switch signal reception is immediately turned off until the second switch detects that the cabinet door is closed again. The first switch standby can be started again after 2 seconds.

[0019] S4. In this case, the first switch is in the closed state and does not receive any signal while the door is open. The first switch opens to the standby state 2 seconds after the door is closed to receive signals. The movement of human hands or body after opening the door will not trigger the first switch, and the movement of the cabinet door when closing the door will not trigger the first switch. The first switch will be opened and standby only after the cabinet door is completely closed and still. The specific delay time is not limited here and can be adjusted according to the specific situation.

[0020] S5. When the cabinet door is stationary, the first switch can receive a signal of a human hand movement outside the door. The sensing distance can be set to be within 50 mm from the first switch. The specific sensing distance is not limited here and is only an example. It can be adjusted according to specific circumstances.

[0021] S6. Because there is a certain distance and time difference between the second switch receiving the door closing signal and the door actually closing and coming to a complete stop, to ensure that the door is completely closed and stationary, it is considered to delay for a certain period after the second switch receives the door closing signal before opening the first switch to wait. This ensures that the first switch does not receive the door movement signal during the closing process. The specific delay length is not limited here and can be adjusted according to specific circumstances.

[0022] Compared with the prior art, the present invention has the following beneficial effects:

[0023] Compared with mechanical rebounders and mechanical switch electric rebounders, the advantage of this design is that there is no need to mechanically press 3mm, and no 3mm gap needs to be reserved between the door and the cabinet; compared with single proximity switch electric door openers, the advantage is that it can improve sensitivity while reducing and eliminating false triggering, thereby improving comfort and reliability.

[0024] The specific embodiments of the present invention will be described in further detail below with reference to the accompanying drawings. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. The following embodiments are used to illustrate the present invention.

[0030] As shown in Figures 1 and 2, a cabinet door pusher based on dual-switch joint control includes a housing composed of an upper housing 1 and a lower housing 3; a mounting assembly for fixing the housing in the cabinet, the mounting assembly including a base, a base 2 being clamped on the lower housing 3, and the base 2 being fixed in the cabinet by other fixing means, or the lower housing 3 can be directly fixed in the cabinet by a fixing mechanism;

[0031] A transmission ejection mechanism is provided in the lower housing 3, and the transmission ejection mechanism includes a motor 5, a reduction gear box 6, a screw 7, a slider 8 and a push rod 9;

[0032] The driving shaft of the motor 5 is connected to the input shaft of the reduction gear box 6, and the output shaft of the reduction gear box 6 is connected to the screw 7. The other end of the screw 7 is screwed into the slider 8, and the slider 8 is fixed to the push rod 9.

[0033] The dual-switch module includes a first switch 10 and a second switch 12. The dual switches are electrically connected to the controller 11, and the controller is electrically connected to the motor 5. The second switch 12 uses either a mechanical door-controlled switch or a non-mechanical door-controlled switch. The first switch 10 uses a non-mechanical switch that can penetrate a static insulating cabinet door to sense human hand and body movements.

[0034] As shown in Figures 1 to 2, in a specific embodiment, two semicircular notches are provided at the ends of the upper shell 1 and the lower shell 3, respectively used to accommodate the second switch 12 and the push rod 9, and the dual switch module is arranged on the lower shell 3; the slider 8 is slidingly connected to the lower shell 3, and the slider 8 is threadedly screwed onto the screw rod 7.

[0035] Furthermore, the second switch 12 is any one of a mechanical door-controlled switch and a non-mechanical door-controlled switch, and the first switch 10 is a non-mechanical switch that can penetrate a static insulating material cabinet door to sense the movement of human hands and body.

[0036] Furthermore, the second switch 12 is a reflective photoelectric door-controlled switch, and the first switch 10 is a capacitive touch switch or a microwave radar sensor switch. To use the switch, the user touches or sweeps the door from the outside with a finger or palm, with the touch or sweep point facing the first switch 10 of the electric door opener.

[0037] For example, the push-out and retraction process of a door opening program can be set to start with a touch outside the door. After activation, the push rod will extend 40mm within 1.5 seconds, followed by a 2-second pause. During this pause, the user can insert a finger into the door gap to open the cabinet door. The push rod then retracts to zero, stops, and waits for the door to be closed before starting again. However, the specific extension length, speed, and pause duration are not limited here and are only examples and can be adjusted according to actual conditions.

[0038] Furthermore, the second switch 12 is a door-controlled switch, which can be set so that when the cabinet door is within 50 mm of the probe, the second switch 12 is determined to be closed, and when the cabinet door is opened more than 50 mm, the second switch 12 is determined to be open.

[0039] The present invention also discloses a control method for a cabinet door opener based on dual-switch joint control, comprising the following steps:

[0040] S1, the second switch 12, is a door-controlled switch that only passively detects whether the door is open or closed. It has no door-opening capability and does not directly participate in the door opening. It provides a signal to control the standby time period of the first switch 10. The implementation method is that the second switch 12 identifies whether the cabinet door is open or closed;

[0041] S2, the first switch 10, can be activated by a human hand touching the static insulating material door panel outside the door; at this time, the controller 11 will control the motor 5 to rotate forward through the reduction gear box 6 and the screw 7 to drive the push rod 9 to move through the slider 8 in the lower housing 3 until the push rod 9 extends out of the housing and pushes the cabinet door open. After a certain pause, the push rod automatically retracts and stops at zero.

[0042] S3. When the second switch 12 detects that the cabinet door is closed, it is set to start the first switch 10 on standby after 2 seconds. At this time, the cabinet door is in a stationary state. The first switch 10 is triggered outside the door, and the door opening program runs. After the first switch 10 is triggered, the first switch 10 signal reception is immediately turned off until the second switch 12 detects that the cabinet door is closed again. The first switch 10 can be started on standby again after 2 seconds. The specific delay time is not limited here and can be adjusted according to specific circumstances.

[0043] S4. In this case, the first switch 10 is in the closed state and does not receive any signal while the door is open. It is only 2 seconds after the door is closed that the first switch 10 is turned on and in the standby state to receive signals. After the door is opened, human movement will not trigger the first switch 10. When the door is closed, the movement of the cabinet door will not trigger the first switch 10. Only after the cabinet door is completely closed and still will the first switch 10 be turned on and in the standby state.

[0044] S5. When the cabinet door is stationary, the first switch 10 can receive a human hand motion signal outside the door. The sensing distance can be set to be within 50 mm from the first switch 10. The specific sensing distance is not limited here and is only an example. It can be adjusted according to specific circumstances.

[0045] S6. Because there is a certain distance and time difference between the second switch 12 receiving the door closing signal and the door actually being completely closed and stationary, to ensure that the door is completely closed and stationary, it is considered to delay for a certain period of time after the second switch 12 receives the door closing signal, and then open the first switch 10 for standby. This ensures that the first switch 10 does not receive the door movement signal when closing the door. The specific delay time is not limited here and can be adjusted according to specific circumstances.
