When the switch door is static or suddenly receives larger external force in the moving process, larger rotating moment and rotating speed larger than the set value are generated in the moment of the switch door, and then the first sliding piece is thrown to the first limiting piece and is abutted with the first limiting piece under the action of centrifugal force, so that the first sliding piece and the switch door are prevented from continuously rotating through the first limiting piece, and further the problem of larger deflection or deformation of the switch door is avoided.

It is further understood that when the first sliding member slides in a direction away from the output shaft, the first elastic member connected to the first sliding member is stretched or compressed to generate elastic deformation, and at this time, the first elastic member drives the first sliding member to slide toward the output shaft. Therefore, when the first sliding piece is abutted to the first limiting piece to cause the switching door to stop rotating, the first elastic piece can recover elastic deformation to drive the first sliding piece to reset, so that the switching door can be continuously normally opened or closed after the external force is eliminated.

Detailed Description

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. It will be apparent that the described embodiments are only some, but not all, of the embodiments of the present application. All other embodiments, which can be made by those skilled in the art based on the embodiments herein without making any inventive effort, are intended to be within the scope of the present application.

The embodiment of the application provides an air conditioner to solve the problem that a switch door of an existing air conditioner is easy to be greatly inclined or deformed when being suddenly subjected to a large external force, and the switch door is described below with reference to the accompanying drawings.

In this embodiment of the application, as shown in fig. 1 and 2, this air conditioner 100 is a cabinet air conditioner and includes a machine body 10, the machine body 10 mainly includes a housing composed of a front panel 11 and a rear panel 13, a heat exchanger 14 installed in the housing, a wind wheel, a wind channel component 15, an electric control box, and other components, an air inlet is provided on the rear panel 13, an air outlet 111 is provided on the front panel 11, the air outlet 111 is provided corresponding to the wind channel port 151 of the wind channel component 15, installed in the wind channel component 15, and after the wind wheel is started, the machine body 10 can suck air through the air inlet, and after heat exchange is completed through the heat exchanger 14, air is blown to the room through the air outlet 111, and then the basic internal circulation heat exchange function is completed.

In order to open and close the air outlet 111, the air conditioner 100 further includes a door opening and closing 20, a driving motor 12 is further installed in the body 10, and the door opening and closing 20 is connected to an output shaft 121 of the driving motor 12, so that the door opening and closing 20 can rotate between an open position for opening the air outlet 111 and a closed position for closing the air outlet 111 in response to rotation of the output shaft 121. Specifically, in the present embodiment, as shown in fig. 1, the opening and closing door 20 includes a door body 21 and a swing arm 22, the door body 21 is located in the machine body 10, one end of the swing arm 22 is connected to the door body 21, and the other end is connected to the output shaft 121. Referring to fig. 3 and fig. 4, fig. 3 shows the opening and closing door 20 in an opened position, and fig. 4 shows the opening and closing door in a closed position, when the driving motor 12 drives the swing arm 22 (i.e. the first swing arm 221) and the door body 21 to rotate clockwise, the opening and closing door 20 rotates to the closed position; when the opposite driving motor 12 drives the swing arm 22 and the door body 21 to rotate counterclockwise, the switch door 20 rotates to the open position. When the driving motor 12 drives the swing arm 22 and the door body 21 to rotate to the closed position, as shown in fig. 4, the swing arm 22 is in an extended state pointing to the air outlet 111, and the door body 21 is located between the air outlet 111 and the air duct port 151 of the air duct member 15, so that the air outlet 111 is closed by shielding the air outlet 111; as shown in fig. 3, when the driving motor 12 rotates the swing arm 22 and the door body 21 to the open position, the swing arm 22 extends substantially in the width direction of the machine body 10, and the door body 21 is located at one side of the air duct member 15 and does not block the air duct opening 151 and the air outlet 111.

In this embodiment, as shown in fig. 3 or fig. 4, the switch door 20 is further provided with a first sliding rail 23, the first sliding rail 23 extends along a radial direction of the output shaft 121, and referring to fig. 2 and fig. 4, the air conditioner 100 further includes a first limiting assembly 30, the first limiting assembly 30 includes a first sliding member 31, a first elastic member 32 and a first limiting member 33, wherein the first sliding member 31 is slidably mounted on the first sliding rail 23; the first elastic piece 32 extends along the first sliding rail 23, and one end of the first elastic piece 32 is fixedly arranged relative to the first sliding rail 23, and the other end of the first elastic piece 32 is connected with the first sliding piece 31; the first limiting member 33 is fixed in the machine body 10, and the first limiting member 33 is used for preventing the first sliding member 31 from rotating around the output shaft 121 when the first sliding member 31 abuts against the first limiting member.

Specifically, in the present embodiment, when the first slide rail 23 needs to be disposed on the switch door 20, the first slide rail 23 may be disposed directly on the swing arm 22, or a support member (such as a support plate, a support rod, a support block, etc.) dedicated to disposing the first slide rail 23 may be added to the door body 21, or the first slide rail 23 may be disposed at a position on the door body 21 having a sufficient radial length (where "radial" refers to the radial direction of the output shaft 121). In addition, the first slide rail 23 may be boss-shaped (e.g., a convex slide rail having an i-shaped, square, or inverted triangle cross section), or may be groove-shaped (e.g., a groove-shaped slide rail having a trapezoid, square, or the like cross section), and the specific shape may be flexibly selected as needed. The first sliding rail 23 is mainly used for sliding the first sliding member 31, so that the first sliding member 31 can slide along the first sliding rail 23 under the action of centrifugal force, and the first sliding rail 23 extends along the radial direction of the output shaft 121. Of course, in practical application, based on factors such as machining error, machining difficulty, width of the swing arm 22, etc., it is also possible that the extending direction of the first slide rail 23 should be allowed to have a certain deviation, for example, the extending direction of the first slide rail 23 does not pass through the output shaft 121, but has a radial distance of less than 5 mm from the output shaft 121.

Referring to fig. 4 and 5, the first sliding member 31 in the first limiting assembly 30 is slidably mounted in the first sliding rail 23, so that the first sliding member 31 can rotate around the output shaft 121 along with the switch door 20, and it can be further understood that when the rotation speed of the switch door 20 is low, the first sliding member 31 is static relative to the switch door 20 under the action of centripetal force (mainly due to the elastic force of the first elastic member 32 and the friction force between the first sliding rail 23 and the first sliding member as centripetal force in the present embodiment), which is not colloquially thrown outward. When the rotational speed of the opening and closing door 20 is high, the first slider 31 can slide away from the output shaft 121 against the centripetal force, that is, the first slider 31 is thrown outward when the rotational speed of the opening and closing door 20 is high.

The first elastic member 32 in the first limiting assembly 30 is specifically a spring, which is also mounted on the switch door 20 and extends along the extending direction of the first sliding rail 23, one end of the first elastic member 32 is fixedly disposed relative to the first sliding rail 23, the other end is connected to the first sliding member 31, for example, as shown in fig. 4, the first sliding rail 23 is in a chute shape, one end of the first elastic member 32 is fixed on an end surface of the chute, and the other end is connected to the first sliding member 31. It will be appreciated that, when the rotational speed of the door 20 is low, the first elastic member 32 may provide a certain centripetal force, so that the first sliding member 31 is stationary relative to the door 20, and smooth opening and closing of the door 20 is ensured. When the rotation speed of the door 20 is high, the first slider 31 slides, and the first elastic member 32 can be stretched or compressed, so as to generate an elastic force to drive the first slider 31 to return after the rotation speed of the door 20 is reduced.

As to whether the first elastic member 32 is stretched or compressed, it is determined by the positional relationship of the first slider 31 and the first elastic member 32, for example, as shown in fig. 5, when the first elastic member 32 is located on the side of the first slider 31 close to the output shaft 121, the first slider 31 stretches the first elastic member 32 when moving in the direction away from the output shaft 121. For another example, the first elastic member 32 is located at a side of the first slider 31 away from the output shaft 121, and the first slider 31 compresses the first elastic member 32 when moving in a direction away from the output shaft 121.

The first limiting member 33 in the first limiting assembly 30 is fixedly installed in the machine body 10, the first limiting member 33 is used for preventing the first sliding member 31 from rotating around the output shaft 121 when the first sliding member 31 is in contact with the first limiting member 33, and the first sliding member 31 and the first limiting member 33 are spaced in the radial direction of the output shaft 121 when the rotation speed of the opening and closing door 20 is less than or equal to a set value; when the rotational speed of the opening/closing door 20 is greater than the set value, the first slider 31 can slide in a direction away from the output shaft 121 and contact the first stopper 33. Specifically, when the first stopper 33 is fixed to the inside of the body 10, it is necessary to space the first stopper 33 and the first slider 31 by a certain distance in the radial direction of the output shaft 121, and when the first slider 31 rotates at a normal speed with the opening and closing door 20, the first stopper 33 and the first slider 31 are still spaced in the radial direction of the output shaft 121 to ensure that the opening and closing door 20 can normally open and close the air outlet 111.

It should be noted that, the "normal speed" refers to a rotational speed of the door 20 when the air conditioner 100 itself is configured to open or close the air outlet 111, and the "normal speed" of the door 20 varies among different air conditioners 100. Therefore, before determining the "set value" defined in the present application, it is necessary to determine the normal speed of opening and closing the door 20 and then determine the set value based on the normal speed of opening and closing the door 20. Specifically, since the opening and closing door 20 instantaneously generates a rotational speed much greater than its normal speed when the opening and closing door 20 suddenly receives a large external force, the set value may be equal to the normal speed of the opening and closing door 20 so that the opening and closing door 20 is stopped in time by the first slider 31 and the first stopper 33 when the opening and closing door 20 receives the external force and the speed increases. However, the rotation speed of the switch door 20 may have a certain fluctuation due to unstable current in the rotation process, that is, the rotation speed of the switch door 20 may be slightly higher than the normal speed thereof when no external force is applied, and the speed of the switch door 20 caused by the sudden and larger external force is usually larger, so the set value may be 2 times, 2.5 times, 3 times, 3.5 times, and so on of the normal speed of the switch door 20, so as to avoid the situation that the rotation speed of the switch door 20 may cause the first slider 31 to slide outwards and abut against the first limiting member 33 when the rotation speed of the switch door 20 fluctuates normally.

After the set value is determined, the specific installation position of the first limiting member 33 is determined according to the set value, and the appropriate first elastic member 32 is selected, so that when the rotation speed of the switch door 20 is greater than the set value, the first elastic member 32 can be stretched or compressed by the first sliding member 31, and the first sliding member 31 can be abutted against the first limiting member 33. For example, after the setting value is determined, the switch door 20 may be rotated sequentially according to the normal speed and the setting value, and simultaneously, two front and rear rotation tracks of the first slider 31 are recorded, and then the first stopper 33 is fixed between the front and rear tracks, so that it is ensured that the first slider 31 may not abut against the first stopper 33 when the switch door 20 is rotated normally, and the first slider 31 may abut against the first stopper 33 when the rotation speed of the switch door 20 is greater than the setting value.

In this embodiment, the first limiting member 33 is configured to prevent the first sliding member 31 from rotating around the output shaft 121 when the first sliding member 31 abuts against the first sliding member, so that the switch door 20 with suddenly increased rotation speed can be stopped in time. The first limiting member 33 may have various structural schemes for achieving the above effects, for example, one of the first limiting member 33 and the first sliding member 31 is convexly provided with saw teeth, and the other is concavely provided with corresponding tooth grooves, and when the first sliding member 31 abuts against the first limiting member 33, the saw teeth are clamped in the tooth grooves; of course, the serrations and tooth grooves may be replaced with hemispherical bumps and hemispherical grooves. For another example, the first limiting member 33 may be provided with a plurality of blocking members (such as a baffle, a blocking strip, etc.), where the plurality of blocking members are arranged at intervals along an arc track, and a limiting groove is formed between two adjacent blocking members, and when the first sliding member 31 abuts against the first limiting member 33, the first sliding member 31 is entirely clamped into the limiting groove between two adjacent blocking members, so as to prevent the first sliding member 31 and the switch door 20 from continuing to rotate. In summary, as long as the first slider 31 abuts against the first limiting member 33, the first limiting member 33 can prevent the first slider from continuing to rotate, and the first slider 31 is not affected to slide toward the output shaft 121, and the specific structural forms of the first limiting member 33 and the first slider 31 can be flexibly selected according to needs.

As will be appreciated from the foregoing, in the air conditioner 100 of the present application, when the opening/closing door 20 is stationary or rotates at its own normal rotational speed, the first slider 31 does not interfere with the first stopper 33, so as to ensure that the opening/closing door 20 can normally open or close the air outlet 111. When the switch door 20 is at rest or suddenly receives a larger external force during movement, the switch door 20 can instantaneously generate a larger rotation moment and a rotation speed larger than a set value, and then the first sliding member 31 can be thrown to the first limiting member 33 under the action of centrifugal force and is abutted against the first limiting member 33, so that the first sliding member 31 and the switch door 20 are prevented from continuously rotating through the first limiting member 33, and further the problem of larger deflection or deformation of the switch door 20 is avoided. It is further understood that when the first sliding member 31 slides away from the output shaft 121, the first elastic member 32 connected to the first sliding member 31 is stretched or compressed to generate elastic deformation, and the first elastic member 32 drives the first sliding member 31 to slide toward the output shaft 121. Therefore, when the first sliding member 31 abuts against the first limiting member 33 to stop the rotation of the switch door 20, the first elastic member 32 will recover the elastic deformation to drive the first sliding member 31 to return, so as to ensure that the switch door 20 can be opened or closed normally after the external force is eliminated.

Alternatively, since the switch door 20 is directly exposed at the air outlet 111 after the air outlet 111 is closed, the switch door 20 is more susceptible to external forces (such as being impacted by a person, a pet, or other things) after the air outlet 111 is closed, and the switch door 20 is further greatly skewed or deformed, so that the air outlet 111 is forced to open. Therefore, in an embodiment, as shown in fig. 4 and 5, the first limiting member 33 is formed with a first limiting surface 331 at least in the closed position, the first limiting surface 331 faces away from the open position, and the first limiting surface 331 is used to limit the first sliding member 31 from rotating towards the open position when the first sliding member 31 abuts against the first limiting surface. Specifically, as shown in fig. 4, in the present embodiment, the open position is located approximately at the right side of the closed position, and the movement of the switch door 20 from the open position to the closed position is clockwise rotation, and the movement from the closed position to the open position is counterclockwise rotation. When the switch door 20 is in the closed position, the first limiting member 33 is at least partially disposed near the first sliding member 31 on the switch door 20, and the first limiting member 33 forms a first limiting surface 331 at least near the first sliding member 31, and the first limiting surface 331 faces clockwise and faces away from the open position. When the switch door 20 suddenly receives a large external force to start rotating from the closed position to the open position, the first sliding member 31 slides in a direction away from the output shaft 121 and abuts against the first limiting surface 331, so that the first sliding member 31 and the switch door 20 are prevented from continuing to rotate by the first limiting member 33, and the switch door 20 is prevented from being deformed to open the air outlet 111 due to large deflection.

Of course, the opening and closing door 20 may be suddenly subjected to a large external force (the schematic view of the external force may refer to fig. 5) directed in a counterclockwise direction during the opening or closing process, and then skew or deform to the opening position, so further, in an embodiment, the first limiting member 33 is formed with a plurality of first limiting surfaces 331 facing away from the opening position, the plurality of first limiting surfaces 331 are located between the closing position and the opening position, and the plurality of first limiting surfaces 331 are arranged along the circumferential direction of the output shaft 121. It can be appreciated that if the switch door 20 suddenly receives a larger external force directed in a counterclockwise direction during the opening or closing process, the switch door 20 suddenly accelerates, and the first sliding member 31 slides towards the first limiting member 33 and abuts against the first limiting surface 331 at the corresponding position, so that the suddenly accelerated switch door 20 stops in time, and larger deflection or deformation of the switch door 20 is avoided.

Further, as shown in fig. 4 and 5, in the forming manner of the plurality of first limiting surfaces 331, in this embodiment, the plurality of first limiting teeth 332 are formed on the first limiting member 33, and the tooth surface of each first limiting tooth 332 facing away from the open position forms the first limiting surface 331; the first slider 31 is formed with a first abutment tooth 311, and the first abutment tooth 311 has a first abutment surface 312 facing the open position, that is, the first abutment surface 312 faces counterclockwise, and just opposite to the first limiting surface 331, and when the rotational speed of the switch door 20 is greater than the set value, the first abutment surface 312 abuts against the first limiting surface 331. It can be appreciated that, by making the first limiting surface 331 formed by the tooth surface of the first limiting tooth 332, and the first sliding member 31 is provided with the corresponding first abutting tooth 311, not only the first sliding member 31 can be abutted to the first limiting surface 331 of the first limiting member 33 more easily, but also the arrangement density of the plurality of first limiting surfaces 331 can be increased, so that when the switch door 20 receives a larger external force pointing to the counterclockwise direction at any position, the first limiting surfaces 331 with relatively close positions can be abutted by the first sliding member 31, and the switch door 20 can be stopped in time.

Optionally, in an embodiment, as shown in fig. 4 or fig. 5, each of the first limiting teeth 332 has a first tooth tip 333, and the plurality of first tooth tips 333 are located on an arc line, which is coaxially disposed with the output shaft 121 of the driving motor 12, and thus the output shaft 121 is disposed with the same radial distance from each of the first tooth tips 333. It can be appreciated that the radial distance between the first abutment tooth 311 and each first limiting surface 331 is the same, so that when the rotational speed of the switch door 20 at any position is greater than the set value, the first sliding member 31 can abut against the first limiting member 33 after sliding for the same distance, thereby facilitating the positioning of the first limiting member 33 and the selection of the first elastic member 32.

Of course, the opening and closing door 20 may be suddenly subjected to a large external force directed in a clockwise direction (the schematic view of the external force may refer to fig. 7) during the opening or closing process, and may be skewed or deformed toward the closed position. Therefore, in one embodiment, the switch door 20 is further provided with a second sliding rail 24, and the second sliding rail 24 extends along the radial direction of the output shaft 121; the air conditioner 100 further includes a second limiting assembly 40, the second limiting assembly 40 including a second slider 41, a second elastic member 42, and a second limiting member 43; the second sliding member 41 is slidably mounted on the second sliding rail 24; the second elastic member 42 extends along the second sliding rail 24, and one end of the second elastic member 42 is fixedly arranged relative to the second sliding rail 24, and the other end is connected with the sliding member; the second limiting member 43 is fixed in the machine body 10, and the second limiting member 43 is used for preventing the second sliding member 41 from rotating towards the closed position when the second sliding member 41 is abutted against the second limiting member; when the rotational speed of the opening and closing door 20 is less than or equal to the set value, the second slider 41 is spaced from the second stopper 43 in the radial direction of the output shaft 121; when the rotational speed of the opening/closing door 20 is greater than the set value, the second slider 41 can slide in a direction away from the output shaft 121 and come into contact with the second stopper 43.

Specifically, in the present embodiment, the second limiting assembly 40 may be provided with reference to the first limiting assembly 30 for preventing the first slider 31 and the switch door 20 from rotating toward the open position in fig. 4 and 5, except that the second limiting member 43 is used for preventing the second slider 41 and the switch door 20 from rotating toward the closed position, and the second limiting assembly 40 operates in the same principle as the first limiting assembly 30.

Therefore, in the same manner as the first slide rail 23, when the second slide rail 24 needs to be disposed on the switch door 20, the second slide rail 24 may be disposed directly on the swing arm 22, or a support member (such as a support plate, a support rod, a support block, etc.) dedicated to disposing the second slide rail 24 may be added to the door body 21, or the second slide rail 24 may be disposed at a position on the door body 21 having a sufficient radial length (where "radial" refers to the radial direction of the output shaft 121). In addition, the second sliding rail 24 may be in a boss shape (e.g., a convex sliding rail with an i-shaped cross section, a square shape, an inverted triangle shape, etc.), or may be in a groove shape (e.g., a groove sliding rail with a trapezoid shape, a square shape, etc.), and the specific shape may be flexibly selected according to the need. However, since the second slide rail 24 is mainly used for sliding the second slide member 41, so that the second slide member 41 can slide along the second slide rail 24 under the action of centrifugal force, the second slide rail 24 extends along the radial direction of the output shaft 121, and of course, in practical application, based on factors such as machining error, machining difficulty, and width of the swing arm 22, a certain deviation should be allowed in the extending direction of the second slide rail 24, for example, the extending direction of the second slide rail 24 does not pass through the output shaft 121, but has a radial distance of less than 5 mm from the output shaft 121, which is also possible.

The second slider in the second limiting assembly 40 is slidably mounted in the second sliding rail 24 in the same manner as the first slider 31, so that the second slider 41 can rotate around the output shaft 121 along with the switch door 20, and it can be further understood that when the rotation speed of the switch door 20 is low, the second slider 41 is static relative to the switch door 20 under the action of centripetal force (mainly by the elastic force of the second elastic member 42 and the friction force between the second elastic member and the second sliding rail 24 as the centripetal force in the present embodiment), so that the second slider is not thrown out conventionally. When the rotation speed of the opening and closing door 20 is high, the second slider 41 can slide away from the output shaft 121 against the centripetal force, that is, the second slider 41 is thrown outward when the rotation speed of the opening and closing door 20 is high.

The second elastic member 42 of the second limiting assembly 40 is specifically a spring, which is also mounted on the switch door 20 and extends along the extending direction of the second sliding rail 24, wherein one end of the second elastic member 42 is fixedly disposed relative to the second sliding rail 24, and the other end is connected to the second sliding member 41, for example, as shown in the figure, the second sliding rail 24 is shaped like a chute, and one end of the second elastic member 42 is fixed on an end surface of the chute, and the other end is connected to the second sliding member 41. It can be appreciated that, when the rotation speed of the door 20 is low, the second elastic member 42 can provide a certain centripetal force, so that the second sliding member 41 is stationary relative to the door 20, and smooth opening and closing of the door 20 is ensured; when the rotation speed of the door 20 is high, the second slider 41 slides, and the second elastic member 42 can be stretched or compressed, so as to generate an elastic force to drive the second slider 41 to return after the rotation speed of the door 20 is reduced.

As to whether the second elastic member 42 is stretched or compressed, it is determined by the positional relationship of the second slider 41 and the second elastic member 42, for example, as shown in fig. 7, when the second elastic member 42 is located on the side of the second slider 41 close to the output shaft 121, the second slider 41 stretches the second elastic member 42 when moving in the direction away from the output shaft 121. For another example, the second elastic member 42 is located at a side of the second slider 41 away from the output shaft 121, and the second slider 41 compresses the second elastic member 42 when moving in a direction away from the output shaft 121.

The second limiting member 43 in the second limiting assembly 40 is fixedly installed in the machine body 10, the second limiting member 43 is used for preventing the second sliding member 41 from rotating towards the closed position when the second sliding member 41 is abutted against the second limiting member, and the second sliding member 41 and the second limiting member 43 are spaced in the radial direction of the output shaft 121 when the rotation speed of the switch door 20 is less than or equal to a set value; when the rotational speed of the opening/closing door 20 is greater than the set value, the second slider 41 can slide in a direction away from the output shaft 121 and contact the second stopper 43. Specifically, when the second stopper 43 is fixed to the body 10, the second stopper 43 and the second slider 41 are spaced apart from each other in the radial direction of the output shaft 121 as needed, and when the second slider 41 rotates at a normal speed with the opening and closing door 20, the second stopper 43 and the second slider 41 are still spaced apart from each other in the radial direction of the output shaft 121 to ensure that the opening and closing door 20 can normally open and close the air outlet 111.

It should be noted that, in this embodiment, the "normal speed" and the set value are the same as those described above, and specific reference is made to the foregoing description. After the set value is determined, the specific installation position of the second limiting member 43 is determined according to the set value, and the second elastic member 42 is selected appropriately, so that when the rotation speed of the switch door 20 is greater than the set value, the second elastic member 42 can be stretched or compressed by the second sliding member 41, so that the second sliding member 41 slides in a direction away from the output shaft 121 and abuts against the second limiting member 43. For example, after the setting value is determined, the switch door 20 may be rotated sequentially according to the normal speed and the setting value, and simultaneously, two front and rear rotation tracks of the second sliding member 41 are recorded, and then the second limiting member 43 is fixed between the front and rear tracks, so that when the switch door 20 rotates normally, it is ensured that the second sliding member 41 does not abut against the second limiting member 43, and when the rotation speed of the switch door 20 is greater than the setting value, the second sliding member 41 may abut against the second limiting member 43.

In this embodiment, the second limiting member 43 is configured to prevent the second sliding member 41 from rotating towards the closed position when the second sliding member 41 abuts against the second sliding member, so that the switch door 20 with suddenly increased rotation speed can be stopped in time. The second limiting member 43 may have various structural schemes for achieving the above effects, for example, one of the second limiting member 43 and the second sliding member 41 is convexly provided with saw teeth, and the other is concavely provided with corresponding tooth grooves, and when the second sliding member 41 abuts against the second limiting member 43, the saw teeth are clamped in the tooth grooves; of course, the serrations and tooth grooves may be replaced with hemispherical bumps and hemispherical grooves. For another example, the second limiting member 43 may be provided with a plurality of blocking members (such as a baffle, a blocking strip, etc.), where the plurality of blocking members are arranged at intervals along an arc track, and a limiting groove is formed between two adjacent blocking members, and when the second sliding member 41 abuts against the second limiting member 43, the second sliding member 41 is entirely clamped into the limiting groove between two adjacent blocking members. In summary, as long as the second slider 41 abuts against the second limiting member 43, the second limiting member 43 can prevent the second slider from continuing to rotate, and the second slider 41 is not affected to slide toward the output shaft 121, and the specific structural forms of the second limiting member 43 and the second slider 41 can be flexibly selected according to needs.

It will be appreciated that, when the switch door 20 is also likely to suddenly receive a larger external force directed clockwise during the opening or closing process, the switch door 20 will suddenly accelerate, and the second slider 41 will slide away from the output shaft 121 and abut against the second limiting member 43, so that the suddenly accelerated switch door 20 stops in time, and the switch door 20 is prevented from being greatly skewed or deformed in the direction of the closed position.

That is, in the present embodiment, the first limiting component 30 is responsible for preventing the switch door 20 from being skewed or deformed toward the open position, and the second limiting component 40 is responsible for preventing the switch door 20 from being skewed or deformed toward the closed position, and the first limiting component 30 and the second limiting component 40 are mutually matched, so that bidirectional protection of the switch door 20 can be achieved, and the switch door 20 can well cope with external forces with larger randomness. Of course, the first limiting assembly 30 or the second limiting assembly 40 may be selectively installed according to the actual stress condition of the switch door 20, for example, when the probability that the switch door 20 receives the external force in the clockwise direction is considered to be smaller based on the installation position of the air conditioner 100 or other structures of the air conditioner 100, only the first limiting assembly 30 may be installed, and the second limiting assembly 40 may not be installed, so as to reduce the production cost of the air conditioner 100.

In addition, in the present embodiment, as shown in fig. 6 and 7, the second stopper 43 is formed with a plurality of second stopper teeth 432, and the tooth surface of each second stopper tooth 432 facing away from the closed position constitutes a second stopper surface 431; the second slider 41 is formed with a second abutment tooth 411, and the second abutment tooth 411 has a second abutment surface 412 facing the closed position, that is, the second abutment surface 412 faces clockwise, and just opposite to the second limiting surface 431, and when the rotation speed of the switch door 20 is greater than the set value, the second abutment surface 412 abuts against the second limiting surface 431. It can be appreciated that, by making the second limiting surface 431 formed by the tooth surface of the second limiting tooth 432, and the second sliding member 41 is provided with the corresponding second abutting tooth 411, not only the second sliding member 41 can be more easily abutted to the second limiting surface 431 of the second limiting member 43, but also the arrangement density of the plurality of second limiting surfaces 431 can be increased, so that when the switch door 20 receives a larger external force pointing in the counterclockwise direction at any position, the second limiting surfaces 431 with relatively close positions can be abutted by the second sliding member 41, and the switch door 20 can be stopped in time.

Alternatively, in an embodiment, as shown in fig. 6 and 7, each of the plurality of second limiting teeth 432 has a second tooth tip 433, and the plurality of second tooth tips 433 are located on an arc line, which is coaxially disposed with the output shaft 121 of the driving motor 12, and thus the output shaft 121 is disposed at the same radial distance from each of the second tooth tips 433. It can be appreciated that the radial distance between the second abutment teeth 411 and each second limiting surface 431 is the same, so that when the rotational speed of the switch door 20 at any position is greater than the set value, the second sliding member 41 can abut against the second limiting member 43 after sliding for the same distance, thereby facilitating the positioning of the second limiting member 43 and the selection of the second elastic member 42.

Optionally, in an embodiment, referring to fig. 1, 4 and 6, the door 20 includes a swing arm 22 and a door body 21, wherein the door body 21 is used for shielding the air outlet 111 to close the air outlet 111, or is used for being dislocated with the air outlet 111 to open the air outlet 111; one end of the swing arm 22 is connected with the door body 21, and the other end is connected with the output shaft 121, so that the swing arm 22 can drive the door body 21 to rotate when rotating along with the output shaft 121, and the door body 21 can be switched between an open position and a closed position. In this embodiment, the swing arm 22 further includes a first swing arm 221 and a second swing arm 222, the first swing arm 221 is provided with a first slide rail 23, and the second swing arm 222 is provided with a second slide rail 24. It can be appreciated that the first sliding rail 23 and the second sliding rail 24 are directly disposed on the first swing arm 221 and the second swing arm 222 of the door 20, and no corresponding supporting members are needed to be disposed for the first sliding rail 23 and the second sliding rail 24, so that the overall structure of the air conditioner 100 is simpler.

That is, the first limiting component 30 is disposed at the first end 25 of the door body 21 and is mainly responsible for preventing the switch door 20 from being skewed or deformed toward the open position, and the second limiting component 40 is disposed at the second end 26 of the door body 21 and is mainly responsible for preventing the switch door 20 from being skewed or deformed toward the closed position, so that the air conditioner 100 is ensured to have a simple structure and low cost on the basis of realizing bidirectional protection of the switch door 20.

Alternatively, in another embodiment, at least one first swing arm 221 and one second swing arm 222 are respectively disposed at two ends of the door body 21 in the height direction, each first swing arm 221 is correspondingly configured with a set of first limiting assemblies 30, and each second swing arm 222 is correspondingly configured with a set of second limiting assemblies 40. For example, two ends of the door body 21 are respectively provided with a first swing arm 221, each first swing arm 221 is correspondingly provided with a group of first limiting assemblies 30, two ends of the door body 21 are respectively provided with a second swing arm 222, and each second swing arm 222 is correspondingly provided with a group of second limiting assemblies 40. It can be appreciated that each end of the switch door 20 may include a first limiting component 30 for preventing the switch door 20 from being skewed or deformed toward the open position, and a second limiting component 40 for preventing the switch door 20 from being skewed or deformed toward the closed position, so as to improve the protection capability of the switch door 20 and better avoid the switch door 20 from being skewed or deformed.

Similarly, as shown in fig. 9, the second sliding rail 24 has a second supporting surface 241, the second sliding member 41 has a second bottom surface 413 facing the second supporting surface 241, and the second bottom surface 413 is provided with a second rolling body 4131 in rolling contact with the second supporting surface 241, so that friction between the second sliding member 41 and the second sliding rail 24 can be reduced, and the situation that the second sliding member 41 is not abutted against the second limiting member 43 in time or even cannot be abutted against the second limiting member 43 due to too large friction force is avoided.
