Description

Technical Field

[0001] This invention relates to the field of air conditioner technology, and more specifically, to an air conditioner. Background Technology

[0002] Currently, many air conditioner indoor units are equipped with a sliding door at the air outlet and a drive device that drives the sliding door to rotate around the circumference of the air conditioner indoor unit. When the air conditioner is idle, the drive device can drive the sliding door to slide to the air outlet to block the air outlet; after the air conditioner is turned on, the drive device can drive the sliding door to slide back in the opposite direction to expose the air outlet.

[0003] However, existing air conditioner indoor units have two sets of drive devices, which are located on both sides of the air outlet. These drive devices drive the left and right sliding doors to slide outside the front panel. The drive devices in these air conditioner indoor units have relatively small strokes. If a drive device with a large stroke is installed, there will be problems with smooth movement. Therefore, the range of angle stroke that can be designed for the sliding door movement is small, which cannot be adapted to air conditioners with large air outlets, thus limiting the scope of application.

[0004] In summary, overcoming the aforementioned shortcomings of existing air conditioners is a technical problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0005] The purpose of this invention is to provide an air conditioner that can alleviate the technical problem in the prior art where air conditioners with large outlets cannot be adapted to sliding doors.

[0006] The air conditioner provided by the present invention includes a sliding door, a drive box, a drive mechanism, and an air outlet frame.

[0007] The drive box is installed on the air outlet frame, which has an air outlet. The ratio of the outer edge length of the drive box to the horizontal length of the air outlet is in the range of 1.5 to 3. The drive mechanism is installed on the drive box and is connected to the sliding door to drive the sliding door to slide on the inside of the front panel of the air conditioner.

[0008] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0009] The air conditioner provided by this invention connects a drive mechanism installed in the drive box to a sliding door. The sliding door slides circumferentially on the inner side of the front panel of the air conditioner, that is, a sliding door is used to cover the air outlet. In this structure, both the sliding door and the drive mechanism are located on the inner side of the front panel. The ratio of the outer edge length of the drive box to the horizontal length of the air outlet is set to 1.5 to 3, that is, the length of the drive box is greater than the length of the air outlet. Based on this, the structure of the drive mechanism that moves the sliding door can be supported by the drive box throughout the entire process, without being suspended, which can ensure structural stability. Thus, the stroke of the drive mechanism can be increased to increase the running length of the sliding door, and the smooth operation of the sliding door can still be guaranteed even after the stroke of the drive mechanism is increased.

[0010] Therefore, the air conditioner provided by the present invention can achieve the cooperation between the sliding door and the large-size air outlet, and can ensure the smooth operation of the sliding door.

The box base is used to be fixedly connected to the air outlet frame, the box cover is fastened to the box base, the drive mechanism is installed inside the drive box, and the box cover is provided with reinforcing ribs.

[0014] The beneficial effect is that when the size of the drive box is increased accordingly due to the need to adapt to a larger air outlet, the cover is not easily deformed due to poor structural strength. Therefore, the air conditioner provided by the present invention can still ensure structural reliability when the air outlet is large.

[0015] Preferably, as one possible implementation, the edge of the lid facing the front panel is an arc-shaped edge, and the reinforcing rib extends along the arc-shaped edge.

[0017] Preferably, as one possible implementation, the reinforcing rib is a single rib, and both ends of the reinforcing rib extend to portions near the two ends of the arc-shaped edge;

[0018] And / or, the reinforcing rib is located on the outside of the lid.

[0019] The beneficial effect is that it can improve the reinforcing effect of the reinforcing ribs on the lid.

[0021] The beneficial effect is that the sliding door can slide stably along the set trajectory.

[0022] Preferably, as one possible implementation, the box cover has a protective cover portion, which is used to cooperate with the box base to form a protective cavity, and the motor is installed in the protective cavity.

[0023] The beneficial effect is that it can protect the motor from moisture.

[0024] Preferably, as one possible implementation, the drive box has a first plug-in portion on the side opposite to the front panel, the first plug-in portion being used to plug into and cooperate with the air outlet frame;

[0025] And / or, the drive box has a second plug-in portion on the side facing the front panel, the second plug-in portion being used to plug into and cooperate with the air outlet frame.

[0026] The beneficial effect is that it not only facilitates improved assembly efficiency but also reduces costs.

[0027] Preferably, as one possible implementation, the two ends of the drive box along the circumferential direction are respectively fixedly connected to the air outlet frame by screws.

[0028] The beneficial effect is that by using screws to lock the drive box, the drive box is prevented from shaking or even falling off.

[0029] Preferably, as one possible implementation, the first insertion part includes a plug, the plug extending in a direction away from the front panel, and the plug being used to engage with a socket on the air outlet frame;

[0030] And / or, the second insertion part includes a pin hole that extends through the front and rear, and the pin hole is used to engage with a positioning pin on the air outlet frame.

[0031] The advantage is that it is very easy to assemble.

[0047] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0048] The present invention will now be described in further detail with reference to specific embodiments and accompanying drawings.

[0049] See Figures 1-3 This embodiment provides an air conditioner, which includes a sliding door 100, a drive box 200, and a drive mechanism 300. The drive box 200 is installed on an air outlet frame 400, the air outlet frame 400 has an air outlet 410, and the ratio of the outer edge length of the drive box 200 to the horizontal length of the air outlet 410 is in the range of 1.5 to 3. The drive mechanism 300 is installed on the drive box 200 and is connected to the sliding door 100 for driving the sliding door 100 to slide on the inside of the front panel of the air conditioner.

[0050] The air conditioner provided by this invention connects the drive mechanism 300 installed in the drive box 200 to the sliding door 100. The sliding door 100 is driven to slide circumferentially on the inner side of the front panel of the air conditioner, that is, the air outlet 410 is covered by a sliding door 100. In this structure, both the sliding door 100 and the drive mechanism 300 are located on the inner side of the front panel. The ratio of the outer edge length of the drive box 200 to the horizontal length of the air outlet 410 is set to a range of 1.5 to 3, that is, the length of the drive box 200 is greater than the length of the air outlet 410. Based on this, the structure of the drive mechanism 300 that drives the sliding door 100 to move can be supported by the drive box 200 throughout the entire process, and will not be suspended, which can ensure the stability of the structure. Thus, the stroke of the drive mechanism 300 can be increased to increase the running length of the sliding door 200, and the smooth operation of the sliding door 100 can still be guaranteed even after the stroke of the drive mechanism 300 is increased.

[0051] Therefore, the air conditioner provided by the present invention can realize the cooperation between the sliding door 100 and the large-size air outlet 410, and can ensure the smooth operation of the sliding door 100.

[0052] In fact, the outer edge length of the drive box 200 is the line length of the projection of the outer side (front side) of the drive box 200 onto the horizontal plane, and the horizontal length of the air outlet 410 is the line length of the projection of the air outlet 410 onto the horizontal plane. The projection of the outer side of the drive box 200 onto the horizontal plane can be curved, and correspondingly, the projection of the air outlet 410 onto the horizontal plane can also be curved. Both the horizontal direction and the horizontal plane mentioned above are relative to the actual state of the air conditioner during use.

[0053] Preferably, the ratio of the outer edge length of the drive box 200 to the horizontal length of the air outlet 410 is between 2.2 and 2.3.

[0054] Specifically, the sliding angle of the sliding door 100 can be set to 65°.

[0055] The drive box 200 and drive mechanism 300 can be configured as two sets, one above the other, located on the upper and lower sides of the air outlet 410 respectively. Preferably, the two drive boxes 200 are symmetrically arranged, which improves structural balance. Correspondingly, the two drive mechanisms 300 can also be symmetrically arranged, which also improves structural balance and drive stability.

[0056] By setting the two ends of the drive box 200 to be located on the left and right sides of the air outlet 410, that is, in the horizontal direction, the area where the air outlet 410 is located is within the angle range of the drive box 200, the smoothness of the sliding door 100 can be further improved.

[0057] See Figure 3 and Figure 4 In the specific structure of the drive box 200, a box base 210 and a box cover 220 can be provided. The box base 210 is fixedly connected to the air outlet frame 400, and the box cover 220 is fastened to the box base 210. In this way, the box cover 220 and the box base 210 can form a cavity structure. The aforementioned drive mechanism 300 can be installed inside the drive box 200. Preferably, a reinforcing rib 221 is provided on the box cover 220 to enhance the structural strength of the box cover 220. Thus, when the size of the drive box 200 is increased to accommodate a larger air outlet 410, the box cover 220 is less likely to deform due to poor structural strength. Therefore, the air conditioner provided in this embodiment can still ensure structural reliability even when the air outlet 410 is large.

[0058] Specifically, the edge of the cover 220 facing the front panel is set as an arc edge, and the reinforcing rib 221 is extended along the arc edge.

[0059] It should be noted that the curved edge of the lid 220 facing the front panel is a part that is more prone to deformation. Therefore, setting a reinforcing rib 221 at the curved edge of the lid 220 can effectively strengthen the lid 220, thereby making the lid 220 less prone to deformation.

[0060] Preferably, the reinforcing rib 221 is set as a single rib rather than multiple reinforcing ribs 221, and the two ends of the reinforcing rib 221 are extended to the two ends of the arc-shaped edge near the lid 220, so as to improve the reinforcing effect of the reinforcing rib 221 on the lid 220.

[0061] Specifically, the reinforcing rib 221 is placed on the outside of the cover 220.

[0062] See Figure 3 In the specific structure of the aforementioned drive mechanism 300, a motor 310, a rack 330, and a gear 320 can be provided. The motor shaft of the motor 310 is coaxially fixed with the gear 320, and the gear 320 meshes with the rack 330. Simultaneously, a track 211 is provided on the housing 210, allowing the rack 330 to engage with the track 211. The track 211 guides the rack 330 and fixes it to the sliding door 100. When the motor 310 operates, it drives the gear 320 to rotate synchronously. The rotation of the gear 320 causes the rack 330 to move along the track 211. Thus, under the guidance of the track 211, the rack 330 can drive the sliding door 100 to slide stably along a set trajectory. The rack 330 will not slip off the track 211; that is, no part of the rack 330 is suspended in the air.

[0063] Preferably, see Figures 3-6 A protective cover 222 can be provided on the cover 220. The protective cover 222 cooperates with the box base 210 to form a protective cavity. The motor 310 is installed in the protective cavity. In this way, the motor 310 is not easily affected by the external environment of the drive box 200, and the motor 310 can be protected from moisture.

[0064] Preferably, see Figure 5 A first plug-in portion can be provided on the side of the drive box 200 away from the front panel, so that the first plug-in portion can be plugged into the air outlet frame 400. During assembly, simply align the first plug-in portion with the corresponding structure on the air outlet frame 400 and push it into the drive box 200 to achieve plug-in engagement between the first plug-in portion and the air outlet frame 400. The connection is very convenient. At this time, the first plug-in portion can serve as a support point for the drive box 200, thereby reducing the number of other fixing structures (such as screws), which not only facilitates the improvement of assembly efficiency but also reduces costs.

[0065] Specifically, the first insertion part includes a plug 212, which is extended away from the front panel. In this way, the plug 212 can be inserted into the socket on the air outlet frame 400. During assembly, the drive box 200 can be pushed from front to back, making assembly very convenient.

[0066] Preferably, there can be two first plug-in portions, and the two first plug-in portions are symmetrically arranged relative to the vertical center face of the drive box 200. In this way, the balance of the drive box 200 under the support of the first plug-in portions can be improved.

[0067] Correspondingly, a second plug-in part can be provided on the side of the drive box 200 facing the front panel, so as to use the second plug-in part to plug into the air outlet frame 400. Similarly, during assembly, simply align the second plug-in part with the corresponding structure on the air outlet frame 400 and push the drive box 200 in to achieve plug-in engagement between the second plug-in part and the air outlet frame 400. The connection is very convenient. At this time, the second plug-in part can also serve as a support point for the drive box 200 to reduce the number of other fixing structures (such as screws), which not only facilitates the improvement of assembly efficiency but also reduces costs.

[0068] Specifically, the second insertion part includes a pin hole 213, which is set as a through hole from front to back. In this way, the pin hole 213 can be inserted and engaged with the positioning pin on the air outlet frame 400. During assembly, the drive box 200 can be pushed from front to back, making assembly very convenient.

[0069] Preferably, a second plug-in portion can be provided, and the second plug-in portion can be located at the middle position of the drive box 200 in the circumferential direction. In this way, the balance of the drive box 200 under the support of the second plug-in portion can be improved.

[0070] Preferably, the first and second plug-in portions are provided simultaneously. In this way, the opposite sides of the drive box 200 can be plugged into the air outlet frame 400 respectively, which can improve the force balance of the drive box 200 after plugging and mating, and can greatly reduce other fixing structures.

[0071] Specifically, the two ends of the drive box 200 along the circumferential direction are fixedly connected to the air outlet frame 400 by screws, so as to lock the drive box 200 with screws and prevent the drive box 200 from shaking or even falling off.

[0072] Specifically, a fixing hole 214 is made on the base 210 of the drive box 200, and the fixing hole 214 is locked with the corresponding threaded hole on the air outlet frame 400 using screws.

[0073] In summary, the embodiments of the present invention disclose an air conditioner that overcomes many technical defects of traditional air conditioners. The air conditioner provided by the embodiments of the present invention can achieve the cooperation between the sliding door and the large-size air outlet, and can ensure the smooth operation of the sliding door.
