Technical Field

[0001] The present invention relates to the technical field of household appliances, and in particular to an installation structure of a wind sweeping blade, an air outlet device and an appliance. Background Art

[0002] Central air-conditioning is developing very rapidly nowadays and is increasingly entering the public eye. Central air-conditioning can also handle many tasks suitable for home air-conditioning. Moreover, the beautiful and elegant design of central air-conditioning and its hidden design have also become its highlights. In addition to the usual indoor and outdoor units, central air-conditioning is equipped with beautiful air outlet devices. Through the hidden design, it can also achieve a delicate fusion of the air outlet frame and the building.

[0003] At present, there are two types of air sweeping designs for air outlet devices: automatic air sweeping and manual air sweeping. The essence of the two air sweeping designs is whether there is a motor drive or not. The structural design is completely different. Two different structures need to be designed to assemble the automatic air sweeping device and the manual air sweeping device, resulting in the incompatibility of the structures of the automatic air sweeping device and the manual air sweeping device, low production efficiency and high cost. Summary of the invention

[0004] In order to solve the technical problem in the prior art that the air sweeping blades cannot be used for both automatic air sweeping and manual air sweeping, the present invention provides an installation structure, an air outlet device and an electrical appliance for the air sweeping blades.

[0005] The technical solution adopted by the present invention is:

[0006] The present invention proposes an installation structure for a wind sweeping blade, which includes a free-rotating mounting seat and a damping-rotating mounting seat respectively arranged on both sides of an air outlet. One end of the wind sweeping blade is a damping mounting end, which can be freely rotatably connected to the free-rotating mounting seat or damping-rotatably connected to the damping-rotating mounting seat; the other end of the wind sweeping blade is a free mounting end, which can be freely rotatably connected to the free-rotating mounting seat or the damping-rotating mounting seat.

[0007] Furthermore, the two ends of the wind sweeping blade are connected to the mounting seats on both sides of the air outlet through rotating grooves. The free rotating mounting seat is provided with a first rotating groove, the damping rotating mounting seat is provided with a second rotating groove, the free mounting end is provided with a third rotating groove plug-fitted with the first rotating groove or the second rotating groove, the damping mounting end is provided with a fourth rotating groove plug-fitted with the first rotating groove or the second rotating groove, and the damping mounting end is also provided with a clamping structure clamped with the free rotating mounting seat or the damping rotating mounting seat.

[0008] The locking structure includes: a plug post arranged at the middle of the fourth rotary groove at the damping mounting end, a locking position arranged on the outer peripheral surface of the plug post, a socket corresponding to the plug post is provided in the middle of the first rotary groove and the second rotary groove, and a notch corresponding to the locking position is provided on the edge of the socket; after the plug post is inserted into the socket of the free rotating mounting seat, the locking position is buckled with the free rotating mounting seat and can slide freely, or after being inserted into the socket of the damping rotation mounting seat, it cooperates with the damping member in the damping rotation mounting seat.

[0009] Preferably, the damping member is a latching tooth, the latching tooth is arranged on a side of the damping rotation mounting seat facing away from the first rotation groove, and the latching tooth is arranged around the insertion hole.

[0010] Furthermore, the fourth rotation groove of the damping mounting end is vacant at a position coaxial with the locking position to form a mounting opening.

[0011] Furthermore, the positions of the insertion holes of the free-rotation mounting seat and the damped-rotation mounting seat are symmetrical, and the setting direction of the notch on the free-rotation mounting seat is opposite to the setting direction of the notch on the damped-rotation mounting seat.

[0012] The present invention also proposes an air outlet device, comprising: an air outlet frame with an air outlet, a sweeping blade installed on the air outlet frame, and a mounting structure for the sweeping blade. One end of the air outlet frame is provided with a mounting position for mounting a driving device. After the driving device is installed, the driving device is used to drive the sweeping connecting rod to drive the sweeping blade to swing.

[0013] The present invention also provides an electrical appliance, comprising the above-mentioned air outlet device.

[0014] Compared with the prior art, the air sweeping blades of the air outlet device of the present invention can be matched with the air outlet frame when installed forward or reversely. When installed forward, it can be used as a manual air outlet device. When installed reversely, a driving device can be added to connect the air sweeping connecting rod to be used as an automatic air outlet device, which improves the versatility of the structure and reduces the manufacturing cost. At the same time, it can prevent the air guide blades from being installed in the reverse direction when installed forward or reversely, thereby improving the installation efficiency.

[0029] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0030] The principle and structure of the present invention are described in detail below with reference to the accompanying drawings and embodiments.

[0031] like Figure 1 , 2 As shown, Figure 1 The figure is a schematic diagram of the structure of the air outlet frame and some blades (only the right half of the air outlet frame is shown in the figure). The air outlet frame 1 is in the shape of a square frame, and the area surrounded by the square frame is the air outlet 6. The wind sweeping blade 23 and the left and right blades 3 are arranged side by side and at intervals in the air outlet 6 area of ​​the air outlet frame 1. The upper and lower ends of the wind sweeping blade 23 and the left and right blades are connected to the upper and lower sides of the air outlet frame. All blades are connected through a horizontal wind sweeping connecting rod 4 to achieve a linkage effect. In this embodiment, the specific arrangement of the blades is that the wind sweeping blade 23 is arranged on the left and right sides of the air outlet, and the left and right blades 3 are arranged between the wind sweeping blades 23. Other arrangements can also be used. The left and right blades 3 use deformable blades, and a driving force is required to drive the left and right blades to swing. If it is an automatic wind sweeping type, the driving force comes from the motor, that is, the motor of the driving device drives the wind sweeping connecting rod 4 to move back and forth in the horizontal direction, so that all the blades follow the wind sweeping connecting rod 4 to swing back and forth to adjust the air outlet direction; if it is a manual wind sweeping type, the driving force comes from the user's manual adjustment, because the wind sweeping blades 23 are arranged on the left and right sides of the air outlet, and are connected to the upper and lower sides of the air outlet frame 1, then as long as a damping component is set at the connection position between the wind sweeping blades 23 and the air outlet frame 1, the whole row of blades driven by the wind sweeping connecting rod (that is, the wind sweeping blades and the left and right blades) can have a certain damping feeling when swinging. In order to design universality, whether it is an automatic wind sweeping type or a manual wind sweeping type, the structure of the air outlet frame and the left and right blades can be set to be the same, and no modification is required. Although the driving source of the automatic air sweeping type air outlet component is not the air sweeping blades, if the air sweeping blades are removed, the gap between the left and right blades and the air outlet frame will be too large, resulting in unstable air sweeping. Therefore, regardless of the automatic air sweeping type or the manual air sweeping type, the air sweeping blades must exist. Under this premise, in order to make the design universal, it is necessary to be able to simultaneously be compatible with automatic air sweeping and manual air sweeping on the same air sweeping blade.

[0032] like Figure 1 As shown, the present invention proposes a mounting structure for a wind sweeping blade, comprising: a free rotation mounting seat 11 and a damping rotation mounting seat 12 arranged on the upper and lower sides of the air outlet of the air outlet frame 1 (the air outlet is specifically the air outlet 6, and can also be other air outlets). One end of the vertical connecting rod 2 of the wind sweeping blade 23 is a damping mounting end 22, and the other end is a free mounting end 21. The two ends of the vertical connecting rod 2 of the wind sweeping blade 23 can be directly mounted with the free rotation mounting seat 11 and the damping rotation mounting seat 12, and the two ends of the vertical connecting rod 2 of the wind sweeping blade 23 can also be directly mounted with the free rotation mounting seat 11 and the damping rotation mounting seat 12 after being turned 180 degrees.

[0033] like Figures 2 to 4As shown, the damping mounting end 22 of the vertical connecting rod 2 is installed on the free rotation mounting seat 11. When the free mounting end 21 is installed on the damping rotation mounting seat 12, the snap-fit ​​structure of the damping mounting end 22 is not matched with the damping member, and the vertical connecting rod 2 of the wind sweeping blade 23 rotates freely. At this time, the wind sweeping connecting rod can be connected to the driving device 5 to automatically sweep the wind.

[0034] like Figure 8 , 9 As shown, the damping mounting end 22 of the vertical connecting rod 2 is mounted on the damping rotation mounting seat 12, and the free mounting end 21 is mounted on the free rotation mounting seat 11. When the vertical connecting rod 2 of the wind sweeping blade 23 rotates, because the snap-fit ​​structure of the damping mounting end 22 directly cooperates with the damping member in the damping rotation mounting seat 12, the vertical connecting rod 2 has a certain resistance, i.e., damping, when rotating, and the stop position of the wind sweeping blade 23 can be manually adjusted.

[0035] That is, the vertical connecting rod 2 of the wind sweeping blade 23 can be used as a manual air outlet device when installed upright, and can be used as an automatic air outlet device by adding a driving device 5 when installed reversely, thereby improving the versatility of the structure and reducing the manufacturing cost.

[0036] Specifically, the mounting seat and the mounting end are connected to each other by means of a rotating groove, which can well realize the universality of forward and reverse installation, and can also be connected by other rotatable ways, all of which are within the protection scope of the present invention.

[0037] like Figures 2 to 7 as well as Fig.10 As shown, the free rotation mounting seat 11 is provided with a first rotation groove 111 in the shape of an annular ring, the damping rotation mounting seat 12 is provided with a second rotation groove 121 with the same shape as the first rotation groove 111, and the free mounting end 21 is provided with a third rotation groove 211 in the shape of an annular ring that is plugged and matched with the first rotation groove 111 or the second rotation groove 121, that is, the first rotation groove 111 or the second rotation groove 121 and the third rotation groove 211 are coaxial and misaligned, so that the first rotation groove 111 or the second rotation groove 121 can be plugged and matched with the third rotation groove 211. The damping mounting end 22 is provided with a fourth rotation groove 221 that is plugged and matched with the first rotation groove 111 or the second rotation groove 121, and the damping mounting end 22 is also provided with a locking structure that is locked with the rotation mounting seat or the damping rotation mounting seat 12, and the locking structure can prevent the damping mounting end 22 from loosening from the mounting seat, and can also provide rotation damping when matched with the damping member, as described below.

[0038] like Figure 8 , 9As shown in Figure 10, the locking structure includes: an insert column 222 and a locking position 223. The insert column 222 is arranged at the axis of the fourth rotary groove 221, that is, the fourth rotary groove 221 surrounds the insert column 222, and the insert column 222 extends axially along the vertical connecting rod 2 of the wind sweeping blade 23. The locking position 223 is arranged on the outer circumferential surface of the insert column 222. The middle part of the first rotary groove of the rotating mounting seat and the damping rotating mounting seat 12 is provided with a socket 13, and the edge of the socket 13 is provided with a notch 14 corresponding to the locking position 223. When installing, the insert column 222 is first inserted into the socket 13, and then the vertical connecting rod 2 is rotated to make the locking position 223 buckled on the side of the mounting seat facing away from the rotary groove.

[0039] The side of the free rotation mounting seat 11 facing away from the rotation groove is a smooth plane, and the latch 223 can slide freely when buckled on the plane, that is, the vertical connecting rod of the wind sweeping blade 23 can rotate freely. A damping member is provided on the surface of the damping rotation mounting seat 12 facing away from the rotation groove to cooperate with the latch 223. When the damping mounting end 22 is inserted into the damping rotation seat, the damping rotation effect is achieved through the cooperation between the latch 223 and the damping member.

[0040] In one embodiment, the damping member is specifically a latching tooth 123 arranged around the latching hole, and a convex tooth is provided on the latching position 223, which cooperates with the latching tooth 123 on the damping rotating seat, and the latching tooth 123 provides resistance during rotation, so as to facilitate manual adjustment of the wind sweeping blade 23. The damping member can also be an elastic paddle, a spring, etc. that cooperates with the latching structure to provide a certain resistance.

[0041] like Fig.11 , 12 As shown, the positions of the insertion holes 13 of the free-rotation mounting seat 11 and the damping rotation mounting seat 12 are symmetrical. To prevent the wind guide blades from being installed upside down, the setting direction of the notch 14 on the free-rotation mounting seat 11 is opposite to the setting direction of the notch 14 on the damping rotation mounting seat 12, further reducing the difficulty of installation.

[0042] The fourth rotary groove 221 is provided with an installation opening at the same axis as the protruding part of the side of the locking structure, that is, the fourth rotary groove 221 has an opening to facilitate the processing and locking of the damping installation end 22, so that the fourth rotary groove 221 is a semi-annular rotary groove or an annular rotary groove with a notch. It is convenient to insert the locking structure during installation, reducing the difficulty of installing the wind sweeping blade.

[0043] like Figure 1 , 2As shown, the present invention also proposes an air outlet device, comprising: an air outlet frame 1, a sweeping blade 23, a sweeping connecting rod 4, left and right blades 3 and the above-mentioned mounting structure. The damping rotation mounting seat 12 is located on the lower side of the air outlet frame 1, the free rotation mounting seat 11 is located on the upper side of the air outlet frame 1, and the two ends of the vertical connecting rod 2 of the sweeping blade 23 are installed in cooperation with the mounting seat. The air outlet frame 1 is in the shape of a square frame, and the area surrounded by the square frame is the air outlet 6. The sweeping blade 23 and the left and right blades 3 are arranged side by side and at intervals in the air outlet 6 area of ​​the air outlet frame 1, and are connected by a horizontal sweeping connecting rod 4 to achieve a linkage effect. The specific arrangement of the blades is that the sweeping blade 23 is arranged on the left and right sides of the air outlet, and a plurality of left and right blades 3 are arranged at intervals between the left and right sweeping blades 23. The leftmost or rightmost side of the air outlet frame 1 is provided with a drive device 5 installation position, and the drive device 5 can be installed.

[0044] In a specific embodiment, when there is one horizontal wind sweeping link 4, the snap-fit ​​position between the wind sweeping blade and the wind sweeping link 4 is located at the center of the wind sweeping blade, and only one snap-fit ​​position is needed. When two snap-fit ​​positions are arranged at intervals above and below the wind sweeping blade 23, two wind sweeping links 4 are arranged corresponding to the snap-fit ​​positions. The number of snap-fit ​​positions on the wind sweeping blade can be determined according to the area of ​​the wind sweeping link, or according to design requirements, and the number is not limited, that is, the number of wind sweeping links 4 is not limited.

[0045] When the air outlet device is an automatic air outlet device, a driving device 5 is installed on the mounting position (it is an existing driving device, which can be driven by a motor, but it is not the focus of this application and will not be described in detail), and the wind sweeping connecting rod 4 is connected to the driving handle of the driving device 5. At the same time, the vertical connecting rod 2 of the wind sweeping blade 23 is reversed, and the damping mounting end 22 of the vertical connecting rod 2 is mounted on the free rotation mounting seat 11. When the free mounting end 21 is mounted on the damping rotation mounting seat 12, the buckle structure of the damping mounting end 22 is not matched with the damping part, so that the driving device 5 can normally drive the wind sweeping connecting rod 4 to move back and forth laterally, and then drive the wind sweeping blade 23 and the left and right blades 3 to sweep the air back and forth through the wind sweeping connecting rod 4.

[0046] When the air outlet device is a manual air outlet device, the installation position of the drive device 5 is vacant, the vertical connecting rod 2 of the wind sweeping blade 23 is installed, the damping installation end 22 of the vertical connecting rod 2 is installed on the damping rotation installation seat 12, and the free installation end 21 is installed on the free rotation installation seat 11. Because the buckle structure of the damping installation end 22 directly cooperates with the damping member in the damping rotation installation seat 12, the vertical connecting rod 2 has a certain resistance, i.e., damping, when rotating. At this time, the wind sweeping blade 23 on the vertical connecting rod 2 has a certain damping when swinging, and the horizontal wind sweeping connecting rod 4 also has a certain damping when moving back and forth horizontally, which can facilitate user positioning and allow the user to manually adjust the direction of the blade.

[0047] The present invention also provides an electrical appliance, including the above-mentioned air outlet device. Specifically, it can be an air conditioner, or an electric fan, a range hood, or other electrical appliances that need to adjust the air outlet direction. Users can choose a suitable air outlet device according to their own needs. Through different assembly methods, automatic air sweeping and manual air sweeping functions can be achieved.

[0048] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
