The specific meaning of the above terms in the present invention can be understood by those skilled in the art according to the specific circumstances.

Reference is first made to fig. 1, 2 and 3. Fig. 1 is a schematic structural diagram of an air conditioner according to an embodiment of the present invention when an air outlet is in a closed state; fig. 2 is a schematic structural diagram of an air conditioner according to an embodiment of the present invention when an air outlet is in an open state; FIG. 3 is an exploded view of an air conditioner according to an embodiment of the present invention; FIG. 4 is an enlarged schematic view of portion A of FIG. 3 showing the first and second slide ends of the door panel; fig. 5 is a schematic view illustrating a structure of a rail unit of a door panel moving mechanism of an air conditioner according to an embodiment of the present invention. As shown in fig. 1 and 2, the air conditioner of the present invention includes a casing 1, where the casing 1 includes a front panel 11 and a left side panel 12, and the front panel 11 is provided with an air outlet, and the air conditioner is further provided with a door panel 3 capable of covering the air outlet 2 and a door panel moving mechanism capable of driving the door panel 3 to move relative to the air outlet 2, and the shape of the door panel 3 matches with the shape of the air outlet 2 so that the door panel 3 can completely cover the air outlet 2, and the shape of the air outlet 2 shown in fig. 1 is substantially rectangular, and the door panel 3 is substantially a planar plate structure, and when the air outlet is in a closed state, the planar plate structure of the door panel 3 can completely cover the rectangular air outlet 2. As shown in fig. 3, the air conditioner further includes a bracket 6 disposed at a position near the air outlet 2 inside the casing 1, and a door moving unit is disposed on the bracket 6. The door panel moving unit includes a driving transmission unit 4 for driving the door panel 3 to move and a rail unit 5, wherein, as shown in fig. 5, the rail unit 5 includes a first rail 51 and a second rail 52; accordingly, as shown in fig. 4, the door panel 3 is provided with the first sliding end 31 and the second sliding end 32, and the first sliding end 31 and the second sliding end 32 are respectively slidably connected with the first guide rail 51 and the second guide rail 52, so that the door panel 3 can slide along with the first sliding end 31 and the second sliding end 32 in the first guide rail 51 and the second guide rail 52 under the driving of the driving unit 4, thereby opening or closing the air outlet 2. And, the first guide rail 51 and the second guide rail 52 are provided so as to be able to flush the door panel 3 with the front panel 11 of the housing 1 with the air outlet 2 closed. As can be seen from fig. 1, in the case of the air outlet 2 being closed, the door panel 3 completely covers the air outlet 2, and the door panel 3 is flush with the surface of the front panel 11, and the door panel 3 and the front panel 11 are closed without gaps.

As can be seen from the above description, the air conditioner according to the present invention has the first guide rail 51 and the second guide rail 52 arranged such that the door panel is flush with the front panel of the housing, thereby the door panel 3 and the front panel 11 achieve a gapless closing, in this case, not only the flatness of the appearance of the air conditioner can be ensured, but also the external dust can be prevented from entering the air conditioner, thereby ensuring the user experience. And, even in the case that the door panel 3 is flush with the front panel 11, the door panel moving on the first and

second guide rails

51 and 52 can still complete the opening or closing of the air outlet, that is, the first and

second guide rails

51 and 52 allow the door panel 3 to have a movement track capable of avoiding the position of the front panel 11 to avoid the interference of the front panel 11 to the movement of the door panel 3, thereby ensuring that the door panel 3 can move smoothly to realize the opening and closing of the air outlet.

In the above case, the rail units may be provided in one or more groups, as shown in fig. 3, and as a specific example, the rail units 5 may be provided in two groups, which are fixed to the upper and lower ends of the bracket 6, respectively, and accordingly, the upper and lower ends of the door panel 3 are provided with the first and second sliding ends 31 and 32, and the movement stability of the door panel 3 may be increased by the above-described two groups of rail units.

Referring to fig. 5 to 9, fig. 6 is a schematic view illustrating a state of a door panel of an air conditioner according to an embodiment of the present invention, wherein the door panel is completely closed; FIG. 7 is a second schematic view of a door panel of an air conditioner according to an embodiment of the present invention, wherein the door panel is retracted to a set position; FIG. 8 is a schematic view III of a door panel of an air conditioner according to an embodiment of the present invention, wherein the door panel is partially opened; fig. 9 is a schematic diagram showing a movement trace of a door panel of an air conditioner according to an embodiment of the present invention, in which the door panel is completely opened. As shown in fig. 5, the first guide rail 51 includes a first portion 511 and a second portion 512, and the first sliding end 31 and the second sliding end 32 on the door panel 3 slide in the first portion 511 and the second guide rail 52, respectively, so that the door panel 3 moves from a direction away from the air outlet 2 to a set position, which is a position away from the air outlet 2, such as a position substantially behind the air outlet 2. As shown in fig. 6, in a state where the air outlet is completely closed, the door panel 3 is flush with the front panel 11, and the door panel 3 is at the closed position. As shown in fig. 7, when the air outlet needs to be opened, the door panel 3 is driven by the driving mechanism to move from the closed position to the set position, and the movement direction of the door panel 3 is approximately towards the rear of the air outlet 2. As shown in fig. 8, after the door panel 3 reaches the set position, in order to further open the air outlet 2, the door panel 3 is moved from the set position to the open position, and at this time, the movement direction of the door panel 3 is substantially along the inner side of the left side panel 12 in a direction away from the air outlet 2. As shown in fig. 9, when the first sliding end 31 and the second sliding end 32 of the door panel 3 are respectively located at the left ends of the second portion 512 and the second guide rail 52, the door panel 3 reaches the open position, and at this time, the door panel 3 is completely hidden behind the left side panel 12, so that the air outlet 2 is completely exposed to the external environment, and the complete opening of the air outlet 2 is achieved. It will be appreciated that when the air outlet 2 needs to be closed, the door panel moves in the opposite direction to the above process, i.e. the door panel 3 moves along the inner side of the left side panel 12 toward the air outlet 2, and moves from the open position to the set position; and then moves forwards towards the direction of the air outlet 2, and moves from the set position to the closed position, so that the air outlet 2 is finally closed.

It can be seen that the movement of the door panel 3 from the closed position to the set position achieves a preliminary opening of the air outlet 2. In this process, the door panel 3 is moved substantially toward the rear of the air outlet 2, i.e., the door panel 3 has a moving direction toward the rear of the air outlet 2. Compared with the traditional guide rail which can only move left and right, the invention ensures that the door plate 3 has a backward movement track by the arrangement of the first part 511 and the second guide rail 52, so that the movement track of the door plate 3 avoids the position of the front panel 11, thereby preventing the front panel 11 from interfering with the movement of the door plate 3. The door panel 3 is then movable by the arrangement of the second portion 512 and the second guide rail 52 substantially along the inner side of the left side panel 12 in a direction away from the air outlet in order to achieve a complete opening of the air outlet 2. The air conditioner of the present invention is configured to realize the opening and closing of the air outlet 2 by dividing the first guide rail 51 into the first portion 511 and the second portion 512 and allowing the first portion 511 and the second portion 512 to be respectively engaged with the second guide rail 52 to independently realize the movement of the door panel 3 in two directions, thereby ensuring that the door panel 3 does not interfere with the front panel 11.

With continued reference to fig. 5, as shown in fig. 5, the first portion 511 is a rail section formed by extending an end of the second portion 512 away from the second rail 52 in a direction toward the air outlet 2. As shown in fig. 6, the first portion 511 is an approximately linear guide rail section disposed at the rear of the air outlet 2, the second portion 512 is an approximately linear guide rail section extending from the right end of the first portion 511, and an included angle greater than 90 ° exists between a connecting line of two ends of the first portion 511 and a connecting line of two ends of the second portion 512, so that the first portion 511 is disposed in an inclined guide rail relative to the second portion 512. By this arrangement, when the door panel 3 is moved away from the air outlet 2 by being pulled by the pivot connection 43, the movement locus thereof is moved toward the rear left of the air outlet 2. And the direction of the pull of the pivot connection is also directed substantially to the left and to the rear, in which case the door panel 3 can slide in the first portion 511 in the direction of the pull of the pivot connection 43 when the pivot connection 43 pulls the door panel 3 for movement. And the inclined guide rail arrangement also facilitates a smooth transition between the first portion 511 and the second portion 512, thereby enabling smooth movement of the first slide end within the first guide rail.

With continued reference to fig. 5 and 6, as shown in fig. 5, the second guide rail 52 includes an arcuate guide rail segment 522, the second portion 512 is a linear guide rail segment, and the two ends of the arcuate guide rail segment 522 form a set angle with the connecting line of the two ends of the second portion 512, the set angle being greater than 90 °. As shown in fig. 6, the arcuate guide rail 522 is disposed inside the left side panel 12, and the second portion 512 is an approximately linear guide rail disposed inside the air outlet 2. In the case that the air outlet needs to be opened, the first sliding end 31 and the second sliding end 32 move along the second portion 512 and the second guide rail 52, so that the door panel 3 has a moving track moving along the inner side of the left side panel 12 in a direction away from the air outlet, and finally, when the door panel 3 moves completely to the inner side of the left side panel 12, the complete opening of the air outlet 2 is realized. Preferably, as shown in fig. 5, the second rail 52 further comprises a third portion 521, the third portion 521 being a rail section formed by an arcuate rail section 522 extending near one end of the first rail 51, the third portion 521 being identical to the first portion 511, i.e. the rail section of the third portion 521 is of equal length and nearly parallel to the rail section of the first portion 511, by which means the door panel can be moved in a translational manner to a set position, thereby ensuring a smooth movement of the door panel 3.

Referring to fig. 4, 5 and 10, fig. 10 is a schematic diagram illustrating a connection structure between a second sliding end and a second rail of an air conditioner according to an embodiment of the present invention. As shown in fig. 4, in a preferred embodiment, the first sliding end 31 is provided with a first annular protrusion 311 in a radial direction near one end of the first rail 51, and the second sliding end 32 is provided with a second annular protrusion 321 in a radial direction near one end of the second rail 52. Further preferably, as shown in fig. 5, a side of the first rail 51 facing the first sliding end 31 is provided with a first bar-shaped protrusion 513 in the length direction of the first rail 51, and a side of the second rail 52 facing the second sliding end 32 is provided with a second bar-shaped protrusion 523 in the length direction of the second rail 52. As shown in fig. 10, taking the cooperation of the second guide rail 52 and the second sliding end 32 as an example, during the movement of the second sliding end 32 in the second guide rail 52, the second annular protrusion 321 contacts with the side wall of the second guide rail 52, and the bottom of the second sliding end 32 contacts with the second bar-shaped protrusion 523, it can be seen that the arrangement of the second annular protrusion 321 and the second bar-shaped protrusion 523 reduces the contact surface between the second sliding end 32 and the second guide rail 52, and reduces the friction therebetween, so as to ensure the smooth movement of the second sliding end 32 in the second guide rail 52, and at the same time, reduce the noise generated by the friction.

Referring to fig. 11 and 12, fig. 11 is a schematic structural view of an air conditioner according to an embodiment of the present invention; fig. 12 is an enlarged schematic view of portion B of fig. 11 showing the door panel movement mechanism. As shown in fig. 11 and 12, the driving transmission unit 4 includes a driving motor 411 fixed on the bracket 6, a gear 412 connected with the driving motor 411, and an arc-shaped rack 42 meshed with the gear 412 and connected with the door panel 3 through a pivot connection piece 43, wherein the driving motor 411 drives the gear 412 to rotate, the gear 412 drives the arc-shaped rack 42 to move, and the arc-shaped rack 42 drives the door panel 3 to move through the pivot connection piece 43 so as to realize the movement of the door panel 3 on the guide rail unit 5. The number of the driving transmission mechanisms can be one or more, and the setting positions of the driving transmission mechanisms can be at the top end, the bottom end or other positions of the door panel 3.

As a specific example, as shown in fig. 1, two sets of driving transmission units 4 are respectively disposed at positions near the upper and lower parts of the door panel 3, each set of driving transmission units 4 includes a driving motor box 41 fixed on the bracket 6, a driving motor 411 and a gear 412 connected with the driving motor 411 are disposed inside the driving motor box 41, each set of driving transmission units 4 further includes an arc-shaped rack 42 in engagement connection with the gear 412 and a pivoting connection member 43 having one end connected with the arc-shaped rack 42, and the other end of the pivoting connection member 43 is connected with the inner side of the door panel 3 (i.e., the side near the inside of the air conditioner), and the two sets of driving transmission units 4 operate synchronously to drive the door panel to move. In the above-mentioned situation, in order to increase the stability of the door panel movement, as shown in fig. 6, a set of guide units 44 may be further added, and a set of guide units 44 may be disposed near the middle of the door panel 3, where the guide units 44 include a guide structure 441, a guide rack 442 penetrating through the guide structure 441 and capable of freely moving back and forth in the interior thereof, and a guide connecting piece 443 having one end connected to the guide rack 442 and the other end connected to the door panel 3, and when the door panel 3 is driven by two sets of driving units to move, the guide rack 442 also moves back and forth in the guide structure 441 to perform the guiding function of the door panel 3.

In summary, the air conditioner of the present invention makes the door panel flush with the front panel of the housing through the arrangement of the first guide rail 51 and the second guide rail 52, thereby ensuring a seamless closure between the door panel and the front panel. And the door panel 3 has a movement track capable of avoiding the position of the front panel 11 through the arrangement of the first guide rail 51 and the second guide rail 52, so that the normal movement of the door panel 3 can be ensured under the condition that the door panel is flush with the front panel, and the closing and opening of the air outlet 2 can be realized. Wherein, divide the first guide rail 51 into the first portion 511 and the second portion 512, through the arrangement of the first portion 511 and the second guide rail 52, the door panel 3 has a backward movement track so as to avoid the position of the front panel 11, the preliminary opening of the door panel 3 is realized, and then through the arrangement of the second portion 512 and the second guide rail 52, the door panel 3 can move along the inner side of the left side panel 12 in a direction away from the air outlet, so as to realize the complete opening of the air outlet 2. By dividing the second guide rail into an arc-shaped guide rail section 522 and a third portion, the third portion is provided as a guide rail section consistent with the first portion so that the door panel can translate to a set position to ensure the stable movement of the door panel 3, and the arc-shaped guide rail section 522 cooperates with the second portion so that the door panel moves from the set position to an open position to realize the complete opening of the air outlet 2. Preferably, friction between the sliding end of the door panel 3 and the corresponding guide rail is reduced by the arrangement of the annular protrusion and the strip-shaped protrusion, thereby ensuring smooth movement of the door panel and also reducing noise generation.
