Description

Technical Field

[0001] The invention relates to the technical field of household appliances, and in particular to a method for controlling automatic door opening and closing of a washing device. Background Art

[0002] The existing washing machine includes a washing machine body, a door frame and a door body. The washing machine body has a washing drum. The door frame is arranged at the opening of the washing drum. One side of the door body is hinged to the door frame, and the other side can be detachably connected to the door frame through a snap-on structure. The snap-on structure includes a snap-on pin and a spring. During the closing process of the door body, the snap-on pin abuts against the spring to force the spring to compress. After the door body is closed, the spring relaxes so that the snap-on pin is inserted into the slot of the door body. After the door body is closed, the opening of the washing drum can be closed. Based on the above-mentioned structural setting, after placing the clothes in the washing drum, the door body needs to be manually closed until it is closed to the position where the door body is snapped with the snap-on pin, and a large force needs to be applied to overcome the elastic force of the spring, resulting in a poor user experience.

[0003] Therefore, it is urgent to study a method for automatically opening and closing the door of a washing machine to improve the user experience. Summary of the invention

[0007] The door automatic closing methods include:

[0008] After the door body in the open position is manually closed to the first angle, the door body can automatically close to the closed position;

[0009] Based on the washing program, it is determined whether the door body in the closed position needs to be locked. Before the washing program is started, the door body remains in the closed position and can be opened manually. When a locking command is issued after the washing program is started, the locking mechanism locks the door body and the door frame, and it cannot be opened manually.

If so, the locking mechanism pushes out the lock tongue to move the door body to the second angle, and the door body is opened to the fourth angle through the mechanical door opener. At the same time, the second base rotates in the opposite direction to the separation position.

[0036] As an optional technical solution of a method for controlling automatic door opening and closing of a washing machine, the process of the door body in the closed position opening to the fourth angle passes through the third angle; the time for the door body to automatically open from the closed position to the third angle is T2;

[0039] When the door body leaves the closed position and moves beyond the third angle, the timing starts. After the timing time exceeds T4 and the door body rotates to the third angle again, the proximity sensor detects the lock tongue and starts timing.

[0052] like Figure 1As shown, this embodiment provides a method for controlling automatic door opening and closing of a washing device, which is applied to washing devices such as washing machines and dryers. The washing device includes a door frame and a door body, and the door body is rotatably arranged on one side of the door frame. The method includes a method for automatically closing the door body, and the method for automatically closing the door body includes: after the door body in the open position is manually closed to a first angle, the door body can automatically close to a closed position abutting against the door frame; based on the washing program, it is determined whether the door body in the closed position needs to be locked, and before the washing program is started, the door body remains in the closed position and can be opened manually; when the washing program is started, a locking command is issued, and the locking mechanism locks the door body and the door frame, and it cannot be opened manually. Among them, the door body is kept in the closed position by the locking force; the locking mechanism locks the door body to the door frame through a mechanical structure.

[0053] The above method allows the user to operate the door only by closing the door body to a smaller first angle and then the door body will automatically close to a closed position, thereby improving the user experience.

[0054] In addition, based on the washing program, it is determined whether the door body in the closed position needs to be locked. Before the washing program is started, the door body remains in the closed position and can be opened manually to facilitate the user to take and put clothes again, thereby improving the convenience of use; when the washing program is started, the locking mechanism locks the door body and the door frame, and it cannot be opened manually to ensure the normal progress of the washing process and the safety of the user.

[0055] In order to prevent the door body from pinching the user and causing harm to the user during the closing process, after the door body is closed to the first angle, the automatic door opening and closing mechanism first closes the door body to the second angle with a first force, and then closes the door body to the closed position with a second force, wherein the second angle is smaller than the first angle, and the second force is greater than the first force. When the door body rotates to the second angle, there is no gap that can pinch the user, and no harm will be caused to the user. In order to close the door body in place, a larger second force is used, which helps to increase the success rate of closing the door body to the closed position.

[0056] The washing device includes two automatic door opening and closing mechanisms, and the door closing action is completed under the action of the two automatic door opening and closing mechanisms. In the first implementation of this embodiment, one of the automatic door opening and closing mechanisms is used to close the door body from a first angle to a second angle, and the other automatic door opening and closing mechanism is used to close the door body from the second angle to a closed position. In the second implementation of this embodiment, one of the automatic door opening and closing mechanisms is used to close the door body from a first angle to a closed position. During the closing process, when the door body is closed to the second angle, the other automatic door opening and closing mechanism is actuated, and the two automatic door opening and closing mechanisms work together to close the door body to the closed position.

[0057] Among them, one of the two automatic door opening and closing mechanisms is a mechanical door opener and the other is an electric door opener and the mechanical door opener and the electric ...

[0058] It should be noted that the mechanical door opener and closer can adopt the design scheme in the prior art, which is not the focus of this application and will not be described in detail.

[0059] The first angle is in the range of 10° to 90°. For example, the first angle is in the range of 30° to 60°, so as to provide a better door closing experience for the user. The second angle is in the range of 1° to 10°.

[0060] The locking end in the existing locking mechanism can be locked with the lock tongue so that the door body cannot be separated from the door frame. However, in order to avoid power outages, manual unlocking can be achieved. Generally, a first fixed seat and a second fixed seat are arranged in the door lock device. The first fixed seat is fixedly connected to the door frame, and the second fixed seat and the first fixed seat are slidably matched through a sliding groove and a sliding protrusion structure, so that the locking mechanism fixed on the second fixed seat can be away from the lock tongue when the second fixed seat is moved, thereby achieving manual unlocking.

[0061] Among them, the first fixed seat and the second fixed seat are slidably matched through the sliding groove and the sliding protrusion. If the size of the sliding groove is too large, it will affect the matching accuracy, and if it is too small, it is easy to get stuck, affecting the user experience.

[0062] To this end, the electric door opener and closer in this embodiment includes a first base, a second base and a locking mechanism, wherein the first base is fixed to the door frame, the first base and the second base are rotatably connected by a rotating pin, and the second base can rotate between a docking position and a separation position relative to the first base, and the locking mechanism is arranged on the second base, when the second base is in the docking position, the locking mechanism can be connected with the lock tongue on the door body, and drive the lock tongue to move to drive the door body to rotate from the second angle to the closed position; wherein the automatic closing method of the door body includes: after the door body is closed to the second angle, the second base rotates from the separation position to the docking position, the door body is moved to the closed position by the locking mechanism, and the second base rotates in the opposite direction to the separation position. This method can realize manual unlocking while avoiding the collision between the lock tongue and the locking mechanism during the manual door closing process again. In addition, the first base is provided with a first rotating hole, the second base is provided with a second rotating hole, and the rotating pin is inserted into the first rotating hole and the second rotating hole. Compared with the slide groove and the sliding protrusion, the processing of the rotating pin and the rotating hole is more convenient, and the precision is easier to control, which reduces the risk of jamming during the rotation process of the second base and improves the user experience.

[0063] During use, due to being in a hurry or other reasons, the user may close the door faster, so that the door body can be closed quickly. When the door body closes faster, under the action of inertia, the door body can automatically close to the closed position. At this time, if the second base is rotated to the docking position again, it will cause redundant actions and affect the time when washing starts, reducing the user experience. To adapt to the above application scenarios, in some embodiments, when the door body rotates to the third angle, the proximity sensor detects the lock tongue, and the timer starts timing, and after the timing reaches T1, the position sensor detects whether the lock tongue is in the closed position, and if so, the locking mechanism does not act; otherwise, the second base rotates from the separation position to the docking position, and the door body is moved to the closed position by the locking mechanism, and the second base rotates in the opposite direction to the separation position; wherein, the third angle is between the first angle and the second angle. In some embodiments, compared with the first angle, the third angle is closer to the second angle. Exemplarily, when the second angle is 1°, the third angle can be 2° or 3°. Wherein, T1 can be 100ms. In other embodiments, T1 can also be 20ms, 50ms, 200ms or 500ms.

[0064] In other embodiments, it is also possible to indirectly determine whether the door body can reach the closed position by other means. For example, it can be determined whether the time for the door body to close from the first angle to the second angle is less than the first preset time. If so, it means that the speed of the door body is relatively large and can move to the closed position under the action of its own inertia, and the electric door opener and closer does not operate. Otherwise, after the door body is closed to the second angle, the second base rotates from the separation position to the docking position, and the door body is moved to the closed position through the locking mechanism, and the second base rotates in the opposite direction to the separation position. In another exemplary embodiment, it is determined whether the speed of the door body when it is closed to the second angle is greater than the preset speed. If so, it means that the door body can move to the closed position under the action of its own inertia, and the electric door opener and closer does not operate. Otherwise, after the door body is closed to the second angle, the second base rotates from the separation position to the docking position, and the door body is moved to the closed position through the locking mechanism, and the second base rotates in the opposite direction to the separation position.

[0065] In some embodiments, after the laundry program is started and a locking command is issued, it is determined whether the door body is in the closed position. If so, the second base is rotated to the docking position, and the locking mechanism and the lock tongue are locked to lock the door body and the door frame. In this state, the door body cannot be opened manually.

[0066] The automatic door opening and closing control method of the washing equipment also includes an automatic door opening method, and the automatic door opening method includes: after receiving the door opening command, the door in the closed position automatically opens to a fourth angle. Among them, the fourth angle is relatively close to the first angle, and the fourth angle and the first angle can also be the same. This method realizes the automatic opening of the door after the laundry is completed, thereby improving the user experience. When the temperature and humidity in the barrel of the washing machine are high, if the user does not open the door of the washing machine in time, it is easy to breed bacteria and even cause secondary pollution to the clothes. The above method can automatically open the door of the washing machine after the laundry is completed, release water vapor, avoid bacterial growth and produce odor, and bring a better user experience to the user.

[0067] In the process of automatic door opening, the automatic door opening and closing mechanism first opens the door from the closed position to the second angle with the second force, and then opens the door from the second angle to the fourth angle with the third force, wherein the second angle is smaller than the fourth angle, and the third force is smaller than the second force. The fourth angle in this embodiment is larger than the third angle, close to or equal to the first angle, and can be reasonably set according to user experience.

[0068] When the door passes the third angle during the opening process, the proximity sensor can detect the lock tongue and start timing. After that, when the timing reaches T1, since the door has been opened, the position sensor cannot detect that the lock tongue is in the closed position. Therefore, the second base will also rotate from the separated position to the docking position, causing the locking mechanism to operate during the door opening process, which may initiate the door closing procedure and affect the safety of use.

[0069] In this embodiment, when the door body is opened to the fourth angle, it will pass through the third angle position, and the proximity sensor can detect the lock tongue, setting the process of increasing the rotation angle of the door body, and the automatic closing method of the door body is not started.

[0070] In some other embodiments, when the door body is in the closed position, the process of opening the door body in the closed position to the fourth angle passes through the third angle; the time for the door body to automatically open from the closed position to the third angle is T2; the timing starts when the door body leaves the closed position, and before the timing reaches T3, the locking mechanism does not act and remains in the separated position; wherein T3>T2. Wherein, T2 can be 200ms. In other embodiments, T2 can also be 100ms, 300ms, 400ms or 500ms. In other embodiments, T3>1.1×T2, T3>1.2×T2 or T3>1.5×T2.

[0071] When the door body leaves the closed position and moves to a position that does not exceed the third angle, the locking mechanism does not operate and remains in the separated position. When the door body leaves the closed position and moves to a position that exceeds the third angle, the timing starts. After the timing time exceeds T4, and when the door body rotates to the third angle again, the proximity sensor detects the lock tongue and starts timing. After the timing time reaches T1, the position sensor detects whether the lock tongue is in the closed position. If so, the locking mechanism does not operate; otherwise, the second base rotates from the separated position to the docking position, and the door body is moved to the closed position through the locking mechanism, and the second base rotates in the opposite direction to the separated position. T4 can be greater than zero. For example, T4 can be 50ms. In other embodiments, T4 can also be 100ms, 300ms, 400ms or 500ms.

[0072] The position sensor is used to detect the lock tongue of the door body in the closed position. When the door body leaves the closed position, the lock tongue cannot be detected. The proximity sensor is used to detect the lock tongue of the door body at the third angle. When the door body leaves the third angle, the lock tongue cannot be detected. Among them, the detection principles of the position sensor and the proximity sensor are common technical knowledge in the field and will not be repeated.

[0073] The washing device includes two automatic door opening and closing mechanisms. The specific method of opening the door body is described in two embodiments. In the first embodiment, the method of automatically opening the door body includes: one of the automatic door opening and closing mechanisms is used to open the door body from the closed position to the second angle; the other automatic door opening and closing mechanism is used to open the door body from the second angle to the fourth angle. In the second embodiment, the method of automatically opening the door body includes: one of the automatic door opening and closing mechanisms is used to open the door body from the closed position to the fourth angle. In the process of opening the door body from the closed position to the second angle, the two automatic door opening and closing mechanisms work together.

[0074] Specifically, of the two automatic door opening and closing mechanisms, one is a mechanical door opener and the other is an electric door opener. There are two ways of the action sequence of the two automatic door opening and closing mechanisms. First, the automatic door opening method includes: the electric door opener and the mechanical ...

[0075] Secondly, when the door body is in the closed position, the electric door opener and the mechanical door opener operate simultaneously to open the door body to a second angle. When the door body is opened to the second angle, the electric door opener stops operating and the mechanical door opener continues operating to open the door body to a fourth angle.

[0076] The electric door opener and closer comprises a first base, a second base and a locking mechanism, wherein the first base is fixed to the door frame, the first base and the second base are rotatably connected by a rotating pin, and the second base can rotate between a docking position and a separation position relative to the first base, and the locking mechanism is arranged on the second base, when the second base is in the docking position, the locking mechanism can connect with the lock tongue on the door body, and drive the lock tongue to move so as to drive the door body to rotate from a second angle to a closed position; wherein the automatic door opening method comprises: after receiving a door opening instruction, determining whether the door body is in a closed position, if so, the locking mechanism pushes the lock tongue out so that the door body moves to the second angle, and the door body is opened to a fourth angle by the mechanical door opener and closer, and at the same time, the second base rotates in the opposite direction to the separation position. This method can complete the automatic opening of the door body, and when the door body is closed again, the lock tongue will not collide with the locking mechanism on the second base, thereby improving the safety of use.

[0077] It should be noted that the locking mechanism can be implemented using existing technical solutions, which is not the focus of this application and will not be described in detail.

[0078] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the embodiments of the present invention. For those skilled in the art, various obvious changes, readjustments and substitutions can be made without departing from the protection scope of the present invention. It is not necessary and impossible to list all the embodiments here. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the claims of the present invention.
