Description

Technical Field

[0001] The present invention belongs to the technical field of air conditioning, and particularly relates to a door panel driving device and a cabinet air conditioner. Background Art

[0002] Generally, there are two kinds of air outlet panel movement devices for existing circular floor-standing air conditioners with direct air outlets: one is to use an air outlet panel (or door panel) to open and close the air outlet, and a separate driving mechanism is used to achieve left and right air sweeping; the other is to use an air outlet panel (or door panel) to open and close the air outlet, and at the same time, the left and right rotation of the air outlet panel is used to achieve the left and right air sweeping function. For the existing first movement device, a set of rotation mechanism for the air outlet panel (or door panel) is required to open or close the air outlet, and at the same time, a separate air sweeping mechanism is required to achieve the left and right air sweeping function, resulting in a large number of device components, high production costs, low assembly efficiency, and in the closed air outlet state, it cannot reach a completely closed state, that is, there is a large gap between the air outlet panel and the air conditioner housing, affecting the overall appearance of the machine and also being unfavorable for the anti-insect and anti-rodent safety design; for the existing second movement device, a set of air outlet panel (or door panel) rotation mechanism is used to achieve both the opening and closing of the air outlet and the left and right air sweeping function at the same time. However, in order to achieve a completely closed state to eliminate the gap with the air conditioner housing, a set of telescopic mechanism is added, resulting in a more complex movement device, a large number of components, high production costs, low assembly efficiency, and increased maintenance difficulty. Summary of the Invention

[0003] Therefore, the technical problem to be solved by the present invention is to provide a door panel driving device and a cabinet air conditioner, which realize the outward push of the door panel during the driving process of the door panel through the variable track design of the door panel sliding arc groove, thereby reducing the gap between the door panel and the air conditioner housing and simplifying the door panel driving structure.

[0004] To solve the above problems, the present invention provides a door panel driving device, including a first fixing member, on which there is a door panel sliding arc groove slidably connected to the door panel. The door panel sliding arc groove has a first circumferential section, a first variable track section, and a second circumferential section. The first variable track section is between the first circumferential section and the second circumferential section, and the first variable track section protrudes and extends toward the outer side of the air conditioner housing. The end of the door panel can be slidably connected to the door panel sliding arc groove through a first sliding connection portion and a second sliding connection portion provided thereon, and the first sliding connection portion and the second sliding connection portion are respectively and correspondingly located in the first circumferential section and the second circumferential section.

[0005] Preferably, the first circumferential section and the second circumferential section are concentrically arranged.

[0006] Preferably, the door panel sliding arc groove further includes a second variable track section, and the second variable track section is at one end of the first circumferential section away from the first variable track section.

[0007] Preferably, the door panel driving device further includes a rotary member and a driving motor. The rotary member is connected to the door panel, and the driving motor can drive the rotary member to rotate.

[0008] Preferably, the rotary member and the door panel are movably connected by a connecting rod.

[0009] Preferably, the rotary member has a first connecting post, the door panel has a second connecting post, and two ends of the connecting rod are respectively pivotally connected to the first connecting post and the second connecting post in a one-to-one correspondence.

[0010] Preferably, the door panel driving device further includes a second fixing member. The first fixing member and the second fixing member are fixedly connected, and the rotary member is located between the first fixing member and the second fixing member.

[0011] Preferably, the first fixing member is further provided with a first sliding arc groove, and the second fixing member is further provided with a second sliding arc groove. A sliding member is arranged on a side surface of the rotary member facing the first fixing member and the second fixing member. A part of the sliding member is slidably connected in the first sliding arc groove, and another part of the sliding member is slidably connected in the second sliding arc groove.

[0012] Preferably, the sliding member includes a translational rotary assembly and / or a rolling rotary assembly. The translational rotary assembly is used for slidingly contacting with a groove side wall of the first sliding arc groove or the second sliding arc groove, and the rolling rotary assembly is used for slidingly contacting with a groove bottom wall of the first sliding arc groove or the second sliding arc groove.

[0013] Preferably, the rotary member further has a bearing post extending toward one side of the door panel. A bearing groove is arranged on the door panel. The bearing post can be inserted into the bearing groove and can slide synchronously in the bearing groove in the sliding direction of the door panel.

[0014] The present invention further provides a cabinet air conditioner, including a door panel driving device and a door panel. There are two door panel driving devices, and the two door panel driving devices are respectively located at the upper and lower ends of the door panel. The door panel driving device is the above-mentioned door panel driving device.

[0015] A door panel driving device and a cabinet air conditioner provided by the present invention. The door panel is slidably connected to the door panel sliding arc groove through the first sliding connection part and the second sliding connection part and is respectively located on both sides of the first rail-changing section. When the air conditioner is in the air-sweeping operation mode, the door panel is driven to reciprocate with a preset displacement along the arc extension direction of the door panel sliding arc groove. At this time, the first sliding connection part and the second sliding connection part are respectively located in the corresponding first circumferential section and the second circumferential section and are not associated with the first rail-changing section. When the air conditioner is in the shutdown (or startup) process, the door panel is driven to move along the arc extension direction and close to the first rail-changing section. The second sliding connection part finally enters the first rail-changing section from the second circumferential section. Since the first rail-changing section protrudes toward the side of the air conditioner housing, the door panel is pushed out toward the side of the air conditioner housing under the action of the first rail-changing section. Thus, the gap between the door panel and the decorative panel when the door panel is in the closed state is reduced. Compared with the prior art in which a special telescopic device is used to reduce the aforementioned gap, the technical solution of the present invention has a simpler structure, and since there is no need to separately provide an external pushing component such as a corresponding motor as in the prior art, the manufacturing cost of the air conditioner is reduced to a certain extent.

[0025] Refer to in combination Figures 1 to 7As shown in the figure, according to an embodiment of the present invention, a door panel driving device is provided, including a first fixing member 1, the position of the first fixing member 1 is fixed relative to the air conditioner housing, and the first fixing member 1 is provided with a door panel sliding arc groove slidably connected to the door panel 101. The door panel sliding arc groove has a first circumferential section 111, a first track-changing section 112, and a second circumferential section 113. The first track-changing section 112 is located between the first circumferential section 111 and the second circumferential section 113, and the first track-changing section 112 protrudes and extends towards the outside of the air conditioner housing. The end of the door panel 101 can be slidably connected to the door panel sliding arc groove through the first sliding connection portion 1011 and the second sliding connection portion 1012 it has, and the first sliding connection portion 1011 and the second sliding connection portion 1012 are respectively located in the first circumferential section 111 and the second circumferential section 113 in a one-to-one correspondence. In this technical solution, the door panel 101 is slidably connected to the door panel sliding arc groove through the first sliding connection portion 1011 and the second sliding connection portion 1012 and is respectively located on both sides of the first track-changing section 112. When the air conditioner is in the swing operation mode, the door panel 101 is driven to reciprocate with a preset displacement along the arc extension direction of the door panel sliding arc groove. At this time, the first sliding connection portion 1011 and the second sliding connection portion 1012 are respectively located in the corresponding first circumferential section 111 and the second circumferential section 113 and are not associated with the first track-changing section 112. When the air conditioner is in the shutdown (or startup) process, the door panel 101 is driven to move along the arc extension direction and close to the first track-changing section 112. The second sliding connection portion 1012 finally enters the first track-changing section 112 from the second circumferential section 113. Since the first track-changing section 112 protrudes towards the side of the air conditioner housing, at this time, the door panel 101 is pushed towards the side of the air conditioner housing under the action of the first track-changing section 112, thereby reducing the gap between the door panel 101 and the decorative panel 1033 when the door panel 101 is in the closed state, and even realizing the complete closing of the door panel 101. Compared with the prior art method of using a special telescopic device to reduce the aforementioned gap, the technical solution of the present invention has a simpler structure, and since there is no need to separately set an external pushing component such as a corresponding motor as in the prior art, to a certain extent, the production and manufacturing cost of the air conditioner is also reduced. At the same time, the technical solution in the present invention is more simplified, which can simplify the assembly process of the door panel driving device and the air conditioner, improve work efficiency, and also reduce the after-sales maintenance difficulty of the air conditioner. The first circumferential section 111 and the second circumferential section 113 can be arranged eccentrically to reduce the processing accuracy requirements of the door panel sliding arc groove. At this time, the smooth sliding operation of the door panel 101 can be ensured by increasing the gap between the first sliding connection portion 1011 and the second sliding connection portion 1012 of the door panel 101 and the groove side wall.Preferably, the first circumferential section 111 and the second circumferential section 113 are concentrically arranged. At this time, the gaps between the first sliding connection part 1011 and the second sliding connection part 1012 of the door panel 101 and the groove side wall can be further reduced, thereby ensuring the stable reliability of the sliding process of the door panel 101. The first sliding connection part 1011 and the second sliding connection part 1012 can be, for example, corresponding cylindrical components with bushings in specific designs.

[0026] It can be understood that when only the first orbit-changing section 112 is provided in the sliding arc groove of the door panel, the second sliding connection part 1012 will swing around the end of the first circumferential section 111 away from the first orbit-changing section 112 as the fulcrum under the drive of the corresponding drive component (at this time, the first sliding connection part 1011 is movably abutted against the end). This kind of swing forms the above-mentioned outward push of the door panel 101, and this swing at one position will cause the gap between the door panel 101 and the decorative panel 1033 to be uneven. Therefore, preferably, the sliding arc groove of the door panel further includes a second orbit-changing section 114. The second orbit-changing section 114 is located at one end of the first circumferential section 111 away from the first orbit-changing section 112. The protruding direction of the second orbit-changing section 114 is the same as that of the first orbit-changing section 112. And preferably, when the cabinet air conditioner is a round cabinet machine, the protruding depths of the first orbit-changing section 112 and the second orbit-changing section 114 are preferably the same, so as to ensure the uniformity of the gap between the door panel 101 and the decorative panel 1033. Of course, when the outer contour of the cabinet air conditioner is not a standard circle, at this time, the protruding depths of the first orbit-changing section 112 and the second orbit-changing section 114 can be reasonably designed according to the size of the air conditioner shell, which will not be elaborated here.

[0027] The door panel driving device includes a rotary member 2 and a driving motor 4. The rotary member 2 is connected to the door panel 101, and the driving motor 4 can drive the rotary member 2 to rotate. Specifically, as Figure 6 shown, a toothed ring 26 is provided on the inner wall of the rotary member 2, and a driving gear 41 is provided on the power output end of the driving motor 4. The driving gear 41 is in tooth engagement with the toothed ring 26. When the driving motor 4 operates, the rotary member 2 drives the door panel 101 to generate a circumferential movement.

[0028] Further, the rotary moving member 2 is movably connected to the door panel 101 through a connecting rod 21. Specifically, the rotary moving member 2 has a first connecting column 22, and the door panel 101 has a second connecting column 1013. Two ends of the connecting rod 21 are respectively pivotally connected to the first connecting column 22 and the second connecting column 1013 in a one-to-one correspondence. The design of the connecting rod 21 forms a displacement margin in the connection between the door panel 101 and the rotary moving member 2, preventing the occurrence of jamming due to inappropriate fitting clearances during the sliding process of the door panel 101.

[0029] Further, the door panel driving device further includes a second fixing member 3. The first fixing member 1 and the second fixing member 3 are fixedly connected, and the rotary moving member 2 is located between the first fixing member 1 and the second fixing member 3. The driving motor 4 can be fixedly connected to the first fixing member 1 or the second fixing member 3. The clamping manner among the first fixing member 1, the second fixing member 3, and the rotary moving member 2 makes the door panel driving device more compact and reliable in structure.

[0030] At this time, a first sliding arc groove 12 is further constructed on the first fixing member 1, and a second sliding arc groove is further constructed on the second fixing member 3. A sliding member is provided on a side surface of the rotary moving member 2 facing the first fixing member 1 and the second fixing member 3. A part of the sliding member is slidably connected in the first sliding arc groove, and another part is slidably connected in the second sliding arc groove. Specifically, the sliding member includes a translational rotation assembly and / or a rolling rotation assembly. The translational rotation assembly is used for sliding contact with a groove side wall of the first sliding arc groove or the second sliding arc groove, and the rolling rotation assembly is used for sliding contact with a groove bottom wall of the first sliding arc groove or the second sliding arc groove. Among them, the translational rotation assembly includes a bushing mounting column 243 on the rotary moving member 2 and a bushing sleeved on the bushing mounting column 243, and the rolling rotation assembly includes a roller mounting seat 242 on the rotary moving member 2 and a roller 241 pivotally connected thereto.

[0031] Further, the rotary moving member 2 further has a bearing column 25 extending toward one side of the door panel 101. A bearing groove 1014 is provided on the door panel 101. The bearing column 25 can be inserted into the bearing groove 1014 and can slide synchronously in the bearing groove 1014 in the sliding direction of the door panel 101. The design of the bearing column 25 can share the gravity of the door panel 101 to a certain extent, thereby ensuring the pressure of the door panel 101 on the component (the first fixing member 1) below it, and further preventing fatigue damage caused by long-term application of the component.

[0032] According to an embodiment of the present invention, a cabinet air conditioner is further provided, which includes a door panel driving device 102 and a door panel 101. There are two door panel driving devices 102, and the two door panel driving devices 102 are respectively located at the upper and lower ends of the door panel 101. The door panel driving device 102 is the above-mentioned door panel driving device. For details, please refer to Figure 7 , the two door panel driving devices 102 are respectively located at the top and bottom of the door panel 101. The two door panel driving devices 102 can adopt different ways in specific detailed structures to adapt to the specific designs of the upper and lower parts of the cabinet air conditioner.

[0033] As Figure 7 shown, the cabinet air conditioner further includes a top cover assembly 1031 and a base assembly 1032. The air conditioner housing is located between the top cover assembly 1031 and the base assembly 1032. The air conditioner housing includes a decorative panel 1033 and an air inlet panel 1036 that are relatively buckled and connected. Inside the air conditioner housing, a door panel 101, a wind deflector component 1037, an air duct component 1034, and a heat exchanger 1035 are sequentially arranged along the direction from the air outlet to the air inlet. It can be understood that the door panel 101 has a door panel air outlet 1015, and the function of the door panel driving device is to ensure whether the door panel air outlet 1015 is aligned with the air outlet on the decorative panel 1033.

[0034] Those skilled in the art can easily understand that on the premise of no conflict, the above-mentioned various advantageous ways can be freely combined and superimposed.

[0035] The above are only the preferred embodiments of the present invention, and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the present invention. The above is only the preferred implementation manner of the present invention. It should be noted that for those of ordinary skill in the art in this technical field, several improvements and modifications can be made without departing from the technical principle of the present invention, and these improvements and modifications should also be regarded as the protection scope of the present invention.
