Description

Technical Field

[0001] The present application relates to the field of air conditioner components, and in particular to a panel lifting mechanism and an air conditioner thereof. Background Art

[0002] The indoor unit of an embedded air conditioner is generally installed at a higher position. After a long period of use, the filter becomes dirty and clogged and needs to be cleaned regularly. However, the higher installation position of the indoor unit of an embedded air conditioner makes it more troublesome to disassemble and install the filter.

[0003] To remove the filter, you need to remove the panel of the embedded air conditioner first. Currently, the embedded air conditioner uses a lifting mechanism to control the lowering and raising of the control panel, which is convenient for quick removal and cleaning of the filter. However, the lifting mechanism in the related art only has a simple lifting function, which is less reliable and prone to false alarms and the problem of the panel not being able to be completely closed after it is raised. Summary of the invention

[0004] The embodiment of the present application provides a panel lifting mechanism and an air conditioner thereof, which can improve the reliability of panel lifting.

[0005] In a first aspect, an embodiment of the present application provides an air conditioner, comprising:

[0006] A lifting module, used to connect to a target position of a panel of an embedded air conditioner indoor unit, wherein the distribution of a plurality of the lifting modules matches the shape of the panel to control the vertical lifting of the panel;

[0007] A closed position detection module is provided in one-to-one correspondence with the lifting module, and is used to detect whether the target position corresponding to the lifting module is closed in place;

[0008] The motion detection module is arranged in one-to-one correspondence with the lifting module, and is used to detect whether the target position corresponding to the lifting module encounters an obstacle.

[0009] In some embodiments, the lifting module includes a motor and a suspension rope, one end of the suspension rope is connected to the output shaft of the electrode, and the other end of the suspension rope is connected to the target position of the panel.

[0010] In some embodiments, the panel is rectangular, and the four lifting modules are distributed in a rectangular shape to connect four target positions of the panel through the hanging ropes.

[0011] In some embodiments, the closed position detection module is a micro switch, which is arranged on one side of the corresponding lifting module and faces the panel, and / or the motion detection module is a micro switch, which contacts the suspension rope to detect the descending resistance of the suspension rope.

[0012] In a second aspect, an embodiment of the present application further provides an air conditioner, comprising a panel and a panel lifting mechanism as in the first aspect, wherein a lifting module of the panel lifting mechanism is connected to the panel; the air conditioner is used for:

[0013] In response to the first instruction, controlling the lifting module to perform a descending action;

[0014] Determine whether the target position is away from the corresponding lifting module by the closed position detection module, and determine whether the target position encounters an obstacle during the descent process by the motion detection module;

[0015] In response to the second instruction, controlling the lifting module to perform a lifting action;

[0016] The closed position detection module is used to determine whether the target position is closed in place.

[0017] In some embodiments, the first instruction is a drop instruction, and the second instruction is a rise instruction or a reset instruction.

[0018] In some embodiments, the air conditioner determines whether the target position is far away from the corresponding lifting module through the closed position detection module, specifically:

[0019] After the lifting module is controlled to perform a descending action for a first preset time, the detection results of all the closed position detection modules are determined;

[0020] When it is detected that any of the target positions is not far away from the corresponding lifting module, the lifting module is controlled to stop the descending action.

[0021] In some embodiments, after controlling the lifting module to stop descending, the air conditioner is further used to:

[0022] When the second instruction is received or it is determined that all the target positions are far away from the corresponding lifting modules after waiting for the first time interval, the fault is cleared and the second instruction is executed or the lifting module is controlled to be in a standby state.

[0023] In some embodiments, after detecting that all the target positions are away from the corresponding lifting modules, the air conditioner periodically determines whether the target position encounters an obstacle during the descent process through the motion detection module, specifically:

[0024] When the motion detection module detects that more than or equal to two of the target positions encounter obstacles, the lifting module is controlled to stop the descending action and a fault is prompted;

[0025] After waiting for a first time interval, re-detecting by the motion detection module whether the target position encounters an obstacle;

[0026] If it is detected that all the target positions have no obstacles, the lifting module is controlled to be in a standby state after the fault is cleared. If it is detected that any of the target positions encounters an obstacle, the fault prompt state is maintained.

[0027] In some embodiments, the air conditioner controls the lifting module to perform a lifting action, specifically controls the lifting module to perform a lifting action according to a target length, and the target length is equal to the descending length of the panel plus a preset length.

[0028] In some embodiments, the air conditioner determines whether the target position is closed in place by the closed position detection module, specifically:

[0029] Determine the length interval where the preset length is located;

[0030] When the lifting module is controlled to rise to a first length, the detection result of the closed position detection module is determined, and the first length is equal to the descending length of the panel plus the minimum value of the length interval;

[0031] When it is detected that at least one of the target positions is not closed in place, after waiting for a second time interval, the lifting module is controlled to perform a descending action according to a second length;

[0032] Perform the ascending motion again.

[0033] In some embodiments, during the process of controlling the lifting module to perform a descending action according to the second length, the air conditioner is also used to control the lifting module to stop the descending action and prompt a fault when it is detected by the motion detection module that at least one of the target positions encounters an obstacle.

[0034] The panel lifting mechanism and air conditioner thereof of the embodiment of the present application have at least the following beneficial effects: a lifting module with multiple panels is adopted, each lifting module is provided with a closed position detection module and a motion detection module, and during the lifting process through the lifting module control panel, the closed position detection module can detect whether the panel is closed in place, or detect whether the panel is away from the lifting module, and the motion detection module can detect whether the panel encounters an obstacle during the lifting process. That is to say, by using the closed position detection module and the motion detection module, the lifting and closing conditions of the panel can be judged more comprehensively, thereby improving the reliability of the air conditioner's control over the panel and ensuring that the panel can be reliably lifted and closed.

[0035] Other features and advantages of the present application will be described in the following description, and partly become apparent from the description, or understood by practicing the present application. The purpose and other advantages of the present application can be realized and obtained by the structures specifically pointed out in the description, claims and drawings.

[0043] In order to make the purpose, technical solutions and advantages of the present application clearer, the present application is further described in detail below in conjunction with the accompanying drawings and examples. It should be understood that the specific embodiments described herein are only used to explain the present application and are not intended to limit the present application. In addition, the characteristics, operations or features described in the specification can be combined in any appropriate manner to form various implementation methods. At the same time, the steps or actions in the method description can also be replaced or adjusted in order in a manner that is obvious to those skilled in the art. Therefore, the various sequences in the specification and the accompanying drawings are only for the purpose of clearly describing a certain embodiment and are not meant to be a necessary sequence, unless otherwise specified that a certain sequence must be followed.

The "connection" and "coupling" mentioned in this application, unless otherwise specified, include direct and indirect connections (couplings).

[0046] The main body of the embedded air conditioner is installed inside the indoor wall, such as on the ceiling. The exposed parts are usually only the decorative shell and the grille panel, which can save indoor space and improve the indoor aesthetics. Since the embedded air conditioner is installed at a high position, if the filter needs to be cleaned, the grille panel needs to be removed first. In order to facilitate the removal of the panel, some embedded air conditioners provide a panel lifting function. Users can remotely control the embedded air conditioner as needed to lower the panel to a suitable position to facilitate the removal and cleaning of the filter.

[0047] Currently, the lifting devices of embedded air conditioner indoor units are relatively simple, without a complete detection mechanism, which may lead to false alarm failures and the panel cannot be completely closed after rising.

[0048] Based on this, an embodiment of the present application provides a panel lifting mechanism and an air conditioner thereof, which adopts a lifting module of multiple panels, and each lifting module is configured with a closed position detection module and a motion detection module. During the lifting process through the lifting module control panel, the closed position detection module can detect whether the panel is closed in place, or detect whether the panel is far away from the lifting module, and the motion detection module can detect whether the panel encounters an obstacle during the lifting process. In other words, by using the closed position detection module and the motion detection module, the lifting and closing conditions of the panel can be judged more comprehensively, thereby improving the reliability of the air conditioner's control over the panel and ensuring that the panel can be reliably lifted and closed.

[0049] The panel lifting mechanism and the air conditioner thereof are described below in conjunction with the accompanying drawings:

[0050] Reference Figure 1 As shown, a panel lifting mechanism provided in an embodiment of the present application includes:

[0051] The lifting module 100 is used to connect to a target position of the panel 400 of the embedded air conditioner indoor unit, and the distribution mode of the plurality of lifting modules 100 matches the shape of the panel 400 to control the vertical lifting of the panel 400;

[0052] The closed position detection module 200 is set in a one-to-one correspondence with the lifting module 100, and is used to detect whether the target position corresponding to the lifting module 100 is closed in place;

[0053] The motion detection module 300 is arranged in one-to-one correspondence with the lifting module 100, and is used to detect whether the target position corresponding to the lifting module 100 encounters an obstacle.

[0054] Figure 1 The grille panel is separated from the decorative panel, and the grille panel can be removed to clean the filter. The grille panel is the panel 400 mentioned in the embodiment of the present application, wherein the lifting module 100 is controlled to perform mechanical movement to lift or lower the panel 400, and each lifting module 100 is connected to a target position on the panel 400, and the target position is the force point for lifting and lowering the panel 400. These target positions are distributed according to the shape of the panel 400, so that the panel 400 can rise or fall parallel to the horizontal plane, for example Figure 1 The middle panel 400 is rectangular, and four target positions are set on the side of the panel 400 facing the lifting module 100. The four target positions are distributed in a rectangular shape. If the four lifting modules 100 are set on the same horizontal plane, all the lifting modules 100 will uniformly perform an ascending action or a descending action, so that the panel 400 can be lifted and lowered vertically. Of course, vertical lifting is a relatively ideal situation. Since the working conditions of each lifting module 100 may be different, resulting in different lifting speeds for different target positions, false alarms may occur, and the panel 400 may not be completely closed after rising. The present application adds a closed position detection module 200 and a motion detection module 300 on the basis of the above. The function of the closed position detection module 200 is to detect whether the panel 400 is closed in place. Refer to Figure 1 That is, to judge whether the grille panel is tightly fitted with the decorative panel when it rises to the highest position. When the grille panel is tightly fitted with the decorative panel, it is considered that the grille panel has been closed in place, that is, the target position on the panel 400 is closed in place. The function of the motion detection module 300 is to detect whether the target position encounters obstacles during the lifting process of the lifting module 100, so as to judge whether the lifting process is smooth. Among them, the target position, the lifting module 100, the closed position detection module 200 and the motion detection module 300 correspond to each other one by one, so as to realize the separate detection of each target position, thereby providing a reliable lifting fault judgment result.

[0055] It can be understood that, at the beginning of the descent, the closed position detection module 200 can determine whether the target position leaves the lifting module 100, during the descent process, the motion detection module 300 can determine whether there are obstacles at the target position, during the ascent process, the motion detection module 300 can determine whether there are obstacles at the target position, and at the end of the ascent, the closed position detection module 200 can determine whether the target position is closed.

[0056] The lifting module 100 includes a motor 110 and a hanging rope 120, one end of the hanging rope 120 is connected to the output shaft of the electrode, and the other end is connected to the target position of the panel 400. The closed position detection module 200 is a micro switch, which is arranged on one side of the corresponding lifting module 100 and faces the panel 400, and / or the motion detection module 300 is a micro switch, which contacts the hanging rope 120 to detect the descending resistance of the hanging rope 120. At this time, if the target position rises to the position, the closed position detection module 200 (micro switch) is triggered to close, and the electric control system receives a low-level output signal. If the target position does not contact the closed position detection module 200 (micro switch), the closed position detection module 200 (micro switch) is triggered to open, and the electric control system receives a high-level output signal. Similarly, during the movement of the suspension rope 120, if there is no obstacle, the suspension rope 120 is tightened to close the motion detection module 300 (micro switch), and the electric control system receives a low-level output signal. If the target position contacts an obstacle, the target position is lifted, so that the suspension rope 120 corresponding to the target position becomes loose, the motion detection module 300 (micro switch) is opened, and the electric control system receives a high-level output signal. The electric control system can quickly and accurately judge the state of each target position through the high and low level outputs of the micro switch, thereby determining whether the lifting process of the panel 400 is abnormal.

[0057] It is understandable that the installation positions of the closure detection module 200 and the motion detection module 300 are not strictly limited, as long as their corresponding functions are met. When a micro switch is used as the closure detection module 200 and the motion detection module 300, it is necessary to provide two scenarios, contact and non-contact, for the micro switch. Therefore, there are certain requirements for the position of the micro switch. If a radar module is used as the closure detection module 200, a tension sensor is used as the motion detection module 300, etc., the position of the closure detection module 200 and the motion detection module 300 can be set according to actual conditions, and no limitation is made here.

[0058] It can be understood that the number of lifting modules 100 is greater than one, which is used to connect multiple target positions to provide stable lifting control, but the specific number of lifting modules 100 is not limited. For example, the number of lifting modules 100 can be three, forming a triangle, with one corner corresponding to the midpoint of one long side of the rectangular panel 400, and the other two corners are symmetrically arranged on the other long side of the rectangular panel 400.

[0059] Reference Figure 1 , 2As shown in FIG. 3 , a control method for panel lifting provided in an embodiment of the present application is applied to an air conditioner having a panel lifting mechanism of the above embodiment, wherein a panel 400 of the air conditioner is connected to a lifting module 100 of the panel lifting mechanism, and the air conditioner performs the following control method, which includes but is not limited to the following steps:

[0060] Step S110, in response to the first instruction, controlling the lifting module 100 to perform a descending action;

[0061] Step S120, determining whether the target position is far away from the corresponding lifting module 100 through the closed position detection module 200, and periodically determining whether the target position encounters an obstacle during the descent process through the motion detection module 300;

[0062] The first instruction corresponds to controlling the lifting module 100 to perform a descending action. For example, the first instruction is a descending instruction, which instructs the electric control system of the air conditioner to control the lifting module 100 to perform a descending action so that the panel 400 descends a certain distance.

[0063] As can be seen above, at the beginning of the descent, the closed position detection module 200 can determine whether the target position leaves the lifting module 100. During the descent process, the motion detection module 300 can determine whether there are obstacles at the target position, thereby determining whether there is any abnormality in the panel 400 during the descent process.

[0064] Step S210, in response to the second instruction, controlling the lifting module 100 to perform a lifting action;

[0065] Step S220 , determining whether the target position is fully closed by the fully closed detection module 200 .

[0066] The second instruction corresponds to controlling the lifting module 100 to perform a lifting action. For example, the second instruction is a lifting instruction, which instructs the air conditioner's electronic control system to control the lifting module 100 to perform a lifting action, so that the panel 400 rises a certain distance or is subjected to an upward pulling force for a period of time (the panel 400 may not move at this time, to ensure that the panel 400 is reliably closed). The second instruction may also be a reset instruction, which resets the panel 400 to the initial position of the embedded air conditioner indoor unit, that is, the position where the panel 400 is closed. At this time, the lifting module 100 needs to perform a lifting action.

[0067] As can be seen above, during the ascending process, the motion detection module 300 can determine whether there is an obstacle at the target position, and at the end of the ascending process, the closure detection module 200 can determine whether the target position is closed.

[0068] Specifically, refer to Figure 4As shown, in the above step S120, the closed position detection module 200 determines whether the target position is far away from the corresponding lifting module 100, including:

[0069] Step S121, after the lifting module 100 is controlled to perform a descending action for a first preset time, a detection result of the fully closed position detection module 200 is determined;

[0070] Step S122: When it is detected that any target position is not far away from the corresponding lifting module 100, the lifting module 100 is controlled to stop the descending action and a fault is prompted.

[0071] Take the lifting module 100 including the motor 110 and the hanging rope 120 as an example for explanation. One end of the hanging rope 120 is connected to the output shaft of the electrode, and the other end is connected to the target position of the panel 400. After the electric control system controls all motors 110 to perform the descending action for the first preset time, it is considered that the panel 400 should have descended a certain distance. At this time, the detection result of all closed position detection modules 200 is determined. If the detection result is that any target position is not far away from the corresponding lifting module 100, that is, at least one of the target positions is still in the closed position, it is considered that the descending process is abnormal, and the lifting module 100 is controlled to stop the descending action. If the detection result is that all target positions are far away from the corresponding lifting module 100, the electric control system believes that there is no problem with the descending process and controls the lifting module 100 to keep executing the descending action. Among them, the first preset time can be 2s or other time.

[0072] If the closed position detection module 200 is a micro switch, the judgment of the above step S122 is that at least one of the target positions is still in contact with the closed position detection module 200 (micro switch) and has not dropped out of the closed position. The electric control system receives a low-level signal from at least one closed position detection module 200 (micro switch), thereby determining that an abnormality has occurred in the descending process and controlling the lifting module 100 to stop the descending action. Similarly, if all target positions are out of the closed position detection module 200 (micro switch), the electric control system receives a high-level signal from all closed position detection modules 200 (micro switches), thereby determining that the descending process is normal and controlling the lifting module 100 to keep executing the descending action.

[0073] Reference Figure 5 As shown, after the aforementioned step S122 controls the lifting module 100 to stop the descending action, the control method further includes:

[0074] Step S123, when the second instruction is received or it is determined that all target positions are far away from the corresponding lifting module 100 after waiting for the first time interval, the fault is cleared and the second instruction is executed or the lifting module 100 is controlled to be in a standby state.

[0075] After the lifting module 100 stops descending, if it receives a descending command from the user again, the indoor unit of the embedded air conditioner will not move, and the panel 400 will maintain the current state. However, if it receives a second command (such as an ascending command or a reset command), it can clear the fault and execute the second command to raise the height of the panel 400, or recheck the state of the closed position detection module 200 (micro switch) after waiting for the first time interval. If all are in the disconnected state, the surface panel 400 has been detached and can wait for further lifting control by the user after the fault.

[0076] Reference Figure 6 As shown, after detecting that all target positions are away from the corresponding lifting module 100, the motion detection module 300 in the above step S120 periodically determines whether the target position encounters an obstacle during the descent process, including:

[0077] Step S124, when the motion detection module 300 detects that more than or equal to two target positions encounter obstacles, the lifting module 100 is controlled to stop the descending action and a fault is prompted;

[0078] Step S125, after waiting for the first time interval, the motion detection module 300 is used to detect again whether the target position encounters an obstacle;

[0079] Step S126: If it is detected that all target positions have no obstacles, the lifting module 100 is controlled to be in a standby state after the fault is cleared; if it is detected that any target position has an obstacle, the fault prompt state is maintained.

[0080] After judging that all target positions are out of the closed position through the above steps, the detection result of the motion detection module 300 is further determined. When the motion detection module 300 detects that more than or equal to two target positions encounter obstacles, it is considered that the descending process is abnormal, and the lifting module 100 is controlled to stop the descending action and prompt a fault. The detection result of the motion detection module 300 is re-determined after the first time interval after the fault prompt. If it is determined that all target positions do not encounter obstacles, the fault is cleared. At this time, the lifting module 100 is in a standby state, waiting for the next control issued by the user through a remote control or the like; if it is still detected that any target position encounters an obstacle, the fault prompt state is maintained.

[0081] It is worth noting that the above step S124 determines that the number of obstacles encountered by the target position is greater than or equal to two, which means that when a detection result of encountering an obstacle at the target position appears, the electronic control system may consider the detection result to be a false alarm and consider continuing to lower the panel 400. However, if two or more detection results of encountering an obstacle appear, the electronic control system determines that an obstacle has been encountered, so the panel 400 is stopped from being lowered.

[0082] The fault prompt may be implemented in a variety of ways, such as sound prompt, indicator light prompt, or push message to the user's smart terminal, etc., which are not limited here. The first time interval may be 2s or other time lengths.

[0083] In the above step S210, the lifting module 100 is controlled to perform the lifting action, specifically:

[0084] The lifting module 100 is controlled to perform a lifting action according to a target length, where the target length is equal to the descending length of the panel 400 plus a preset length.

[0085] Take the lifting module 100 including the motor 110 and the hanging rope 120 as an example for explanation. One end of the hanging rope 120 is connected to the output shaft of the electrode, and the other end is connected to the target position of the panel 400. The electric control system controls all motors 110 to perform the rising action. In order to ensure that the panel 400 can be closed reliably, the distance corresponding to the rising action of the motor 110 is greater than or equal to the current descending length of the panel 400. That is to say, when the preset length is not 0, after the panel 400 rises the distance of the current descending length, the motor 110 still outputs a distance corresponding to the rising action, so that the panel 400 is close to the closed position. Among them, the preset length can be set according to actual needs.

[0086] Reference Figure 7 As shown, in the above step S220, the closed position detection module 200 determines whether the target position is closed in place, including:

[0087] Step S221, determining the length interval where the preset length is located;

[0088] Step S222, when the lifting module 100 is controlled to rise to a first length, the detection result of the closed position detection module 200 is determined, and the first length is equal to the descending length of the panel 400 plus the minimum value of the length interval;

[0089] Step S223, when it is detected that at least one target position is not closed in place, after waiting for a second time interval, the lifting module 100 is controlled to perform a descending action according to a second length;

[0090] Step S225, performing the ascending action again.

[0091] Assuming that the current descending distance of the panel 400 is L, the preset length is 30cm, and the length interval of the preset length is [20,40), when the motor 110 of the lifting module 100 controls the ascending distance to be equal to L+20cm, the judgment of step S222 is executed to determine the detection results of each closed position detection module 200, because at this time the ascending distance of the panel 400 should exceed its descending distance L; when it is detected that at least one target position is not closed in place, indicating that the ascending process of the panel 400 may be abnormal, then after waiting for the first time interval, the motor 110 is controlled to descend the panel 400 by a second length, so that the panel 400 is out of the closed position, which is equivalent to making the closed position detection module 200 detect that the panel 400 is out of place. Then the motor 110 is controlled again to perform the ascending action. At this time, performing the ascending action may cause the panel 400 to close in place again. Among them, the second length can be 5cm or other lengths, and the second time interval can be 1s or other durations. The above preset length can be set according to actual needs, so multiple length intervals can also be set to cover different situations.

[0092] When the closed position detection module 200 is a micro switch, the electric control system detects the closing status of each closed position detection module 200 (micro switch). If all are closed, that is, all are low level, the electric control system considers that the panel 400 is closed. If any of the closed position detection modules 200 (micro switch) is disconnected and outputs a high level, it is considered that the corresponding target position is not closed. After waiting for the second time interval, the control motor 110 is controlled to perform the descending action. At this time, all the closed position detection modules 200 (micro switches) will generally become disconnected, and then the ascending action is performed.

[0093] In the process of controlling the lifting module 100 to perform a descending action according to the second length in the above step S223, the control method further includes:

[0094] Step S224: When the motion detection module 300 detects that at least one target position encounters an obstacle, the lifting module 100 is controlled to stop the descending action and prompts a fault.

[0095] This step is to detect whether the target position encounters an obstacle through the motion detection module 300 when the panel 400 is out of the closed position and descends. If it is detected that at least one target position encounters an obstacle, it is considered that the lifting process is abnormal, all motors 110 are controlled to stop, and a fault is prompted. Among them, the fault prompt can be implemented in a variety of ways, such as sound prompts, indicator light prompts, and push messages to the user's smart terminal, etc., which are not limited here.

[0096] In summary, the embodiment of the present application adopts a lifting module 100 with multiple panels 400, and each lifting module 100 is configured with a closed position detection module 200 and a motion detection module 300. When the panel 400 is lifted and lowered by the lifting module 100, the closed position detection module 200 can detect whether the panel 400 is closed or whether the panel 400 is far away from the lifting module 100, and the motion detection module 300 can detect whether the panel 400 encounters an obstacle during the lifting process. In other words, by using the closed position detection module 200 and the motion detection module 300, the lifting and closing conditions of the panel 400 can be judged more comprehensively, thereby improving the reliability of the air conditioner's control over the panel 400 and ensuring that the panel 400 can be reliably lifted and closed.

[0097] The three processes of the panel lifting control method are described in detail below through a specific example.

[0098] First, refer to Figure 1 In the structure shown, the lifting module 100 is a combination of a motor 110 and a suspension rope 120, and the closed position detection module 200 and the motion detection module 300 are both micro switches. The number of the lifting modules 100, the closed position detection module 200 and the motion detection module 300 are all 4 and correspond to each other. Among them, the closed state of the closed position detection module 200 indicates that the closure is in place, and the closed state of the motion detection module 300 indicates that the suspension rope 120 is tightened and there is no obstacle.

[0099] 1. Descending process:

[0100] When the embedded air conditioner indoor unit receives a descending command (the target descending distance is L), the motor 110 is controlled to execute the descending action. After 2 seconds, the state of each closed position detection module 200 is determined. If the number N of the closed position detection modules 200 in the closed state is 0, the motor 110 is controlled to continue to execute the descending action; if the number N of the closed position detection modules 200 in the closed state is not 0, the motor 110 is controlled to stop and a fault message is displayed. At this time, the user issues a descending command again, and the motor 110 does not move; at this time, if an ascending command is received or a fault occurs, and the number N of the closed position detection modules 200 in the closed state is detected to be 0 after 2 seconds, the fault is cleared and the ascending command is executed or the motor 110 is controlled to enter the standby state;

[0101] When the current descending distance h is between 0 and the target descending distance L, the state of each motion detection module 300 is determined. If the number of motion detection modules 300 in the disconnected state n≤1, the motor 110 is controlled to continue the descending action; if the number of motion detection modules 300 in the disconnected state n>1, all motors 110 stop the action and display a fault message. After stopping the action for 2s, the state of the motion detection module 300 is determined again. If the number of motion detection modules 300 in the disconnected state n=1 at this time, the fault message can be cleared and the user is waiting to manually control the lifting action.

[0102] When the current descending distance of the panel 400 is h=L, all the motors 110 are stopped and descended into place.

[0103] The descent process can be referred to Table 1 below:

[0104] Table 1. Falling Logic Table

[0105]

[0106]

[0107] 2. Rising process and reset process:

[0108] When the embedded air conditioner indoor unit receives a rising command (rising to the closed position, the rising distance is L), the motor 110 is controlled to perform the rising action. During the rising action, the motor 110 replies a rising signal to the electronic control system, and the electronic control system determines the current rising distance in real time.

[0109] Assume that the electric control system gives the ascending distance controlled by the motor 110 equal to L+30cm. During the ascending process, when the ascending distance controlled by the motor 110 is equal to L+20cm, the state of each closed position detection module 200 is judged. If the number of closed position detection modules 200 in the closed state N=4, the motor 110 stops and ascends to the position. If the number of closed position detection modules 200 in the closed state N<4, a signal is returned to the electric control system, and the electric control system controls all electric controls to perform the descending action after an interval of 1s.

[0110] During the descent process, the state of each motion detection module 300 is determined. If the number of motion detection modules 300 in the disconnected state n>1, all motors 110 stop moving and display a fault message. At this time, the user issues a descending command again, and the motor 110 does not move. If the number of motion detection modules 300 in the disconnected state n≤1, all motors 110 perform an ascending action after descending 5cm.

[0111] The rising process or reset process can refer to the following table 2:

[0112] Table 2. Rise or Reset Logic Table

[0113]

[0114]

[0115] It can be seen that this example uses multiple sensors / micro switches to achieve detection and control, and the lifting process of panel 400 is more precise; at the same time, combined with multiple attempts in the lifting process, for example, during the rising process of panel 400, if the panel 400 is not closed tightly, it can automatically descend and then rise again, and intelligently make multiple attempts to effectively avoid the problem of external interference during the rising process causing the panel 400 to fail to rise into place. During the descent of panel 400, multiple sensors / micro switches are used for detection, and it can stop immediately when encountering obstacles, avoiding damage to valuables during the lifting process; therefore, the above control method can effectively reduce problems such as false alarms during the lifting process of panel 400, and reduce user complaints.
