Description

Technical Field

[0001] The utility model belongs to the technical field of air outlet adjustment of air conditioners and relates to a wind shielding device of an air outlet frame of a central air conditioner. Background Art

[0002] The air outlet of a central air conditioner is usually embedded in the wall, and the air outlet direction is controlled by the blades arranged on the air outlet. However, the blades have a single function to adjust the wind direction of the air outlet, and it is impossible to completely avoid direct blowing of the air conditioner. Some products also set wind shields on the air outlet of the central air conditioner with reference to the wind shields used in wall-mounted air conditioners, which partially solves the problem of direct blowing of the air conditioner. However, since the wind shields are usually fixed on the air outlet, the adjustment of the air outlet direction depends entirely on the ability of the wind shield to rotate itself, and thus the choices of air outlet size and air outlet direction provided to consumers are still very limited. Utility Model Content

[0003] In view of the problem that the size and wind direction of the air outlet of the existing central air conditioner are rarely adjusted, the utility model provides a wind shielding device for the air outlet frame of the central air conditioner, the device comprises a wind shielding plate for blocking the air outlet frame from the air outlet frame and a connecting member connecting the wind shielding plate to the air outlet frame, characterized in that a sliding bar is provided at one end of the connecting member connected to the air outlet frame, the wind shielding device also comprises a track for sliding the sliding bar, and the track is arranged on the frame edge of the inner frame of the air outlet frame;

[0004] The slide bar includes a slide bar body and a sliding end sliding on the track, wherein the sliding end is telescopically connected to the slide bar body so that the sliding end enters the track or leaves the track;

[0005] or;

[0006] The track has a space for installing and removing the slide bar, and the slide bar enters the track through the space or is separated from the track through the space.

[0007] The slide bar can slide freely on the track, and can drive the wind shield to move on the air outlet frame of the central air conditioner. Compared with a fixed wind shield, the position of the wind shield changes, thereby providing more air adjustment options (such as air adjustment angle and air adjustment size).

[0008] In addition, the user can freely increase or decrease the number of sliders on the track. For example, for a slider with a telescopic function, the sliding end can enter and exit the track through the telescopic function relative to the slider body, that is, when the number of windshields needs to be increased, the sliding end is allowed to enter the track, and when the number of windshields needs to be reduced, the sliding end is allowed to detach from the track. For sliders without a telescopic function, the track of the utility model has empty spaces for installing and removing the sliders. When the number of windshields needs to be increased, the slider enters the track through the empty spaces, and when the number of windshields needs to be reduced, the slider detaches from the track through the empty spaces. Through the above-mentioned structural setting, the number of windshields involved in the windshielding of the central air-conditioning outlet frame can be adjusted according to actual needs. Different windshields can use different windshield angles and adopt different arrangements (for example, adjacent windshields can be close together or separated by some empty spaces), thereby greatly improving the wind adjustment capacity of the windshield device of the utility model.

[0009] In addition, the utility model also adopts the following technical solutions:

[0010] The telescopic connection is to connect the sliding end to the slide bar body through an elastic member, the track is a slide bar, and the sliding end is provided with a slide groove for the slide bar to be inserted into; or; the track is a slide groove, and the sliding end is a slider inserted into the slide groove;

[0011] When the track is a slide groove, the slider is provided with a resisting surface that resists the slide groove notch, and the slide groove notch pushes the slider to retract in the direction of the slide bar body through the resisting surface until the slider slides into the slide groove and the slider re-extends relative to the slide bar body; when the track is a slide bar, the slide groove notch is provided with a resisting surface that resists the slide bar, and the slide bar pushes the slide groove to retract in the direction of the slide bar body through the resisting surface until the slide bar slides into the slide groove and the slide groove re-extends relative to the slide bar body; the resisting surface is an inclined surface or an arc surface;

[0012] A limiting groove and a limiting protrusion moving in the limiting groove are provided between the sliding end and the slide body. When the sliding end performs telescopic movement relative to the slide body, the limiting protrusion is simultaneously driven to move in the limiting groove.

[0013] Part of the limiting groove or part of the limiting protrusion is exposed outside the slide bar;

[0014] The telescopic connection is to connect the sliding end to the slide bar body through threads;

[0015] The windshield device also includes a plug that blocks the end of the track adjacent to the empty space and prevents the slide from detaching from the track, and a mounting position for mounting the plug is provided on the edge of the inner frame, or the plug at least partially covers the end of the track adjacent to the empty space;

[0028] This section is a detailed description of the content of the utility model. The utility model provides a windshield device for a central air-conditioning air outlet frame, the device includes a windshield plate for blocking the air outlet frame from blowing out and a connector connecting the windshield plate to the air outlet frame, a sliding bar is provided at one end of the connector connected to the air outlet frame, the windshield device also includes a track for sliding the sliding bar, the track is arranged on the frame edge of the inner frame of the air outlet frame, the sliding bar includes a sliding bar body and a sliding end sliding on the track, as described in the content of the utility model, in some embodiments, the sliding end is telescopically connected to the sliding bar body, for example, the simplest way is to connect the sliding end to the sliding bar body through a thread, and rotate the sliding end to make the sliding end telescopic relative to the sliding bar body. Another way is to connect the sliding end to the sliding bar body through an elastic member, for example, a spring or an elastic sheet is used to connect the sliding end to the sliding bar body. By changing the telescopic state of the sliding end and the sliding bar body, the sliding end can be controlled to enter the track or detach from the track, so that the number of windshields can be increased or decreased arbitrarily.

[0029] As a specific embodiment, the track is a slide bar, and the slide end is provided with a slide groove for the slide bar to be inserted. When in use, the slide end is retracted toward the slide bar body, so that the slide groove opening of the slide end is aligned with the slide bar, and then the slide end is extended relative to the slide bar body again, so that the slide bar is inserted into the slide groove of the slide end, so that the slide end enters the track. When the slide end needs to be detached from the track, the slide end is first retracted toward the slide bar body, the slide bar is moved out of the slide groove of the slide end and detached from the slide groove opening, and then the slide end is extended relative to the slide bar body to a natural state. In another specific embodiment, the track is a slide groove, and the slide end is a slider inserted into the slide groove, and the use is similar to the above.

[0030] The extension and retraction of the sliding end relative to the slider body may usually be limited. For example, in some embodiments, a limit groove and a limit protrusion that moves in the limit groove are added between the sliding end and the slider body. The extension and retraction range of the sliding end relative to the slider body is limited by the movement range of the limit protrusion in the limit groove, but part of the limit groove or part of the limit protrusion is exposed outside the slider, so that the operator can indirectly control the extension and retraction of the sliding end relative to the slider body by controlling the movement of the limit protrusion in the limit groove.

[0031] Of course, the present invention also provides an improvement that facilitates the sliding end to enter the track, that is, when the track is a slide groove, the sliding end is a slider, and a resisting surface that resists the slide groove groove opening is provided on the slider, and the slide groove groove opening pushes the slider to retract in the direction of the slide bar body through the resisting surface until the slider slides into the slide groove, and the slider extends out again in the direction of the slide bar body; when the track is a slide rod, the slide groove groove opening is provided with a resisting surface that resists the slide rod, and the slide rod pushes the slide groove to retract in the direction of the slide bar body through the resisting surface until the slide rod slides into the slide groove, and the slide groove extends out again in the direction of the slide bar body; the resisting surface is an inclined surface or an arc surface, so that the sliding end can slide into the track smoothly.

[0032] The utility model also provides a method for controlling the slide bar to enter the track or detach from the track without setting the slide bar to be retractable. For example, in some embodiments, the track has a space for installing and removing the slide bar, and the slide bar enters the track or detaches from the track through the space. The space can be set at any position of the track. For a general track, its length is the same as the length of the inner frame edge of the central air conditioner outlet frame. The space can be set at the end of the track, and of course it can also be set in the middle of the track. When the slide bar enters the track through the empty space, some embodiments add a plug that blocks the end of the track adjacent to the empty space and prevents the slide bar from detaching from the track. A mounting position for installing the plug is provided on the edge of the inner frame. When the slide bar enters the track and the number of slide bars on the track reaches the requirement, the plug is installed on the mounting position. Alternatively, a mounting position for installing the plug may not be provided, and the plug is directly at least partially covered over the end of the track adjacent to the empty space to prevent the slide bar from detaching from the track at the empty space during sliding. When the number of slide bars on the track needs to be reduced, the plug is detached from the mounting position or the end of the track adjacent to the empty space, and the slide bar can detach from the track through the empty space again.

[0033] In order to better connect the windshield, the connecting member includes a support rod for connecting the windshield in addition to the slide bar. The support rod can be an integral structure with the slide bar. Of course, the utility model recommends that the support rod and the slide bar be a separate structure. For example, in some embodiments, the support rod is threaded or clamped with the slide bar, so as to facilitate disassembly to reduce the packaging space of the windshield device. A further optimization scheme is that the slide bar is provided with a sliding track for the support rod to slide. When the support rod slides on the sliding track, it can also provide a sliding direction perpendicular to the sliding direction of the slide bar, so as to further increase the movement range of the windshield and enhance the ability of the windshield to adjust the air outlet of the air conditioner. In the specific implementation, the utility model can refer to the scheme of leaving a space on the track for the slide bar to enter or detach from the track, and set an access position on the sliding track for the support rod to enter and exit the sliding track.

[0034] Example 1

[0035] See Figure 1 and Figure 2The present embodiment provides a wind shield device for a central air-conditioning air outlet frame, comprising a track arranged on an inner frame edge 2 of the central air-conditioning air outlet frame and a connecting member connecting a wind shield plate 5 and the central air-conditioning air outlet frame, the connecting member comprising a slide bar and a support rod 4, the slide bar comprising a slide bar body 1 and a sliding end 6, the slide bar body 1 and the sliding end 6 are connected by a spring 7, a limiting groove 9 is arranged on the slide bar body 1, a limiting protrusion 8 is arranged on the sliding end 6, the limiting protrusion 8 moves in the limiting groove 9, thereby limiting the telescopic movement range of the sliding end 6 relative to the slide bar body 1, in the present embodiment, the track is a slide groove 3, and the sliding end 6 is a slide When the slide bar needs to enter the track, the notch of the slide groove 3 abuts against the abutment surface 10 of the slider, so that the sliding end 6 retracts toward the slide bar body 1, and then slides into the slide groove 3 by the elastic force of the spring 7, and the sliding end 6 extends relative to the slide bar body 1 again. If the slide bar needs to leave the track, the part of the limiting protrusion 8 exposed on the surface of the slide bar can be manually moved to make the sliding end 6 retract toward the slide bar body 1 and then leave the track. Of course, it is also possible not to move the limiting protrusion 8, and directly apply force to the slide bar body 1 to push the slide bar body 1 to move toward the sliding end 6 at one end, and the sliding end at the other end of the slide bar body 1 can be detached from the track.

[0036] The support rod 4 and the slide bar are an integrated structure, and the support rod 4 is spherically connected to the wind shield 5, so that the wind shield 5 can freely rotate relative to the support rod 4.

[0037] Example 2

[0038] See Figure 3 This embodiment is basically the same as the embodiment 1, except that the sliding end 12 is threadedly connected to the slide bar body 11, and the sliding end 12 can be inserted into the slide groove 13 to enter the track by rotating the sliding end 12, and the sliding end 12 can be disengaged from the slide groove 13 by rotating the sliding end 12 in the opposite direction.

[0039] Example 3

[0040] See Figure 4 and Figure 5 This embodiment provides another wind shielding device for an air outlet frame of a central air conditioner. The device is partially the same as that of Embodiment 1, except that the slide bar 17 is an integral structure and is not retractable. An empty space 16 is provided at the end of the track 14 adjacent to the inner frame 15 of the air outlet frame, and the slide bar 17 enters or detaches from the track 14 through the empty space 16.

[0041] Example 4

[0042] Example 4 is basically the same as Example 3, see Figure 6The difference is that a plug 18 is added to at least partially cover the end of the track 14 adjacent to the inner frame 15 of the air outlet frame, and the plug 18 can be removed from the end. In this way, when there is no need to increase or decrease the sliding bars on the track 14, the plug 18 can be put on to prevent the sliding bars from detaching from the track 14 through the empty space. When the number of sliding bars on the track 14 needs to be adjusted, the plug 18 can be removed, and when the number reaches the requirement, the plug 18 can be put on again.

[0043] Example 5

[0044] Example 5 is basically the same as Example 4, see Figure 7 The difference is that an installation position 19 for installing a plug 20 is added to the inner frame. In this embodiment, the installation position 19 is a threaded hole, and the plug 20 is a screw. After the screw is screwed into the threaded hole, the end of the track 14 close to the inner frame of the air outlet frame can be blocked to prevent the slide bar from detaching from the track 14 through the empty space. When the number of slide bars on the track 14 needs to be adjusted, the screw can be unscrewed, and the screw can be screwed in again after the number reaches the requirement.

[0045] Example 6

[0046] Example 6 is basically the same as Example 3, see Figure 8 The difference is that the support rod 24 and the slide bar 21 do not adopt an integrated structure, but a split structure, wherein the slide bar 21 is provided with a sliding rail, which is slidably connected to the slide groove 23 at the bottom of the support rod 24, and the sliding rail is provided with an access position 22 for the slide groove to enter and exit the sliding rail.

[0047] Example 7

[0048] Example 7 shows all the components of the wind shield device described in Example 5, which includes four wind shields 30, four slide bars 32 and four support rods 33, which correspond to each other one by one. After installation, the wind shield 30 completely covers the central air-conditioning air outlet frame. By adjusting the rotation angle of the wind shield 30 and the support rod 33, different air-conditioning air outlets are provided. Since the number of slide bars can be freely increased or decreased, there can be empty spaces between the wind shields 30. For example, if only three wind shields are used, the air outlet in the empty spaces between the wind shields is in the form of direct blowing. Similarly, the number of wind shields can be increased, so that the rotation of each wind shield relative to the support rod can fine-tune the air-conditioning air outlet. In addition, the sliding of the slide bars and the support rod makes the position of the wind shield extremely varied, thereby greatly improving the adjustment range of the air-conditioning air outlet.

Those skilled in the art should understand that the utility model is not limited by the above embodiments.
