Description of the embodiments
In order to make the objects, technical solutions and advantages of the present invention more apparent, the technical solutions of the present invention will be described in detail below. It will be apparent that the described embodiments are only some, but not all, embodiments of the invention. All other embodiments, based on the examples herein, which are within the scope of the invention as defined by the claims, will be within the scope of the invention as defined by the claims.
Example 1
The air conditioner wind gap opening and closing mechanism that this embodiment provided includes drive belt 1, first roller shutter 2, first filter screen 3, second roller shutter 4, second filter screen 5 and power supply, wherein:
the drive belt 1 may be wrapped, i.e. the drive belt 1 is made of a flexible material, such as rubber, so that it forms a loop end to end. The belt 1 is connected to a power source so that the belt 1 is driven to rotate in the circumferential direction of the endless loop by the power source.
The first rolling curtain 2 and the second rolling curtain 4 are formed by arranging a plurality of wind shielding strips, and the first filter screen 3 and the second filter screen 5 are both net structures. The first roller shutter 2, the first filter screen 3, the second roller shutter 4 and the second filter screen 5 are all installed on the driving belt 1, and the first roller shutter 2, the first filter screen 3, the second roller shutter 4 and the second filter screen 5 are sequentially distributed in the circumferential direction of the ring, wherein the first roller shutter 2 is connected with the first filter screen 3, and the second roller shutter 4 is connected with the second filter screen 5. A first recess 6 is formed between the first screen 3 and the second roller blind 4 and a second recess 7 is formed between the second screen 5 and the first roller blind 2.
Through the structure, when the air conditioner air inlet opening and closing mechanism is installed at the air conditioner air inlet, the driving belt 1 is driven by the power source to rotate until the first roller shutter 2 is opposite to the first gap 6, the second roller shutter 4 is opposite to the second gap 7, the first roller shutter 2, the first gap 6, the second roller shutter 4 and the second gap 7 are arranged at the air conditioner air inlet, the first roller shutter 2 and the second roller shutter 4 at the moment form a sealing component for sealing the air conditioner air inlet, so that the air conditioner air inlet is closed, when the air conditioner is started, the driving belt 1 is driven by the power source to rotate along the first direction, the driving belt 1 drives the first roller shutter 2, the first filter screen 3, the second roller shutter 4 and the second filter screen 5 to rotate until the first filter screen 3 and the second gap 7 are opposite to each other, the second filter screen 5 is opposite to the first gap 6, and the first filter screen 3 and the second filter screen 5 are all arranged at the air conditioner air inlet, and the first filter screen 3 and the second filter screen 5 at the moment form a permeable filter component for opening the air conditioner air inlet, as shown in fig. 7, 8 and 9. Because the first roller shutter 2, the first filter screen 3, the second roller shutter 4 and the second filter screen 5 are sequentially installed on the ring formed by the driving belt 1, the first gap 6 is located between the first filter screen 3 and the second roller shutter 4, and the second gap 7 is located between the second filter screen 5 and the first roller shutter 2, the air inlet only needs to rotate by an angle X (namely, a first preset angle) smaller than 180 DEG from closing to opening. When the air conditioner is closed, the driving belt 1 is driven by the power source to continue rotating by an angle Y (namely a second preset angle) along the first direction, so that the first roller shutter 2 is opposite to the first gap 6, the second roller shutter 4 is opposite to the second gap 7, and the first roller shutter 2, the second roller shutter 4, the first gap 6 and the second gap 7 are all arranged at the air conditioner air inlet, as shown in fig. 1, 5 and 6, the first roller shutter 2 and the second roller shutter 4 at the moment form a sealing assembly for sealing the air conditioner air inlet, thereby closing the air conditioner air inlet. Since the first roller shutter 2, the first filter screen 3, the second roller shutter 4 and the second filter screen 5 are sequentially installed on the ring formed by the driving belt 1, the first gap 6 is located between the first filter screen 3 and the second roller shutter 4, and the second gap 7 is located between the second filter screen 5 and the first roller shutter 2, the rotating Y angle of the air inlet is smaller than 180 ° from closing to opening.
In summary, it can be seen that when the air conditioner air inlet opening and closing mechanism provided by the embodiment is installed at the air conditioner air inlet to open and close the air inlet, the air inlet can be opened and filtered only by driving the power source to rotate by an angle X along one direction, the air inlet can be closed by continuously rotating by an angle Y along the direction, and the angles X and Y are smaller than 180 degrees. In addition, the above-mentioned opening and closing mechanism that this embodiment provided can rotate along a direction when opening and close the air conditioner air intake, and the power supply only need drive belt 1 along a direction rotation can promptly, need not the power supply just reverse, so can prolong the life of power supply and promote the reliability of use, and then make the user experience feel better.
Optionally, the first roller shutter 2, the first filter screen 3, the first gap 6, the second roller shutter 4, the second filter screen 5, and the second gap 7 each occupy one sixth of the total length of the driving belt 1, that is, the lengths of the first roller shutter 2, the second roller shutter 4, the first filter screen 3, the second filter screen 5, the first gap 6, and the second gap 7 are all the same.
Therefore, in the process from closing the air inlet to opening the air inlet, the power source only needs to drive the driving belt 1 to rotate 60 degrees along the first direction, the air inlet can be converted from an air inlet closing state (namely, the first roller shutter 2 is opposite to the first gap 6, the second roller shutter 4 is opposite to the second gap 7, the first roller shutter 2, the second roller shutter 4, the first gap 6 and the second gap 7 are all positioned on the air inlet), and the air inlet opening state (namely, the first filter screen 3 is opposite to the second gap 7, the second filter screen 5 is opposite to the first gap 6, and the first filter screen 3, the second filter screen 5, the first gap 6 and the second gap 7 are all positioned on the air inlet), and the rotation angle is one third of the integral structure of the conventional roller shutter filter screen. When the air inlet is in an open state to a closed state, the power source only needs to drive the driving belt 1 to rotate 120 degrees along the first direction, and the rotation angle is two thirds of that of the existing roller shutter filter screen integrated structure. In the process from closing to opening to closing of the air inlet, the driving belt 1 only needs to rotate 180 degrees, and the rotation angle is half of that of the existing roller shutter filter screen integrated structure.
It should be noted that, if the power source drives the driving belt 1 to rotate 60 ° along the first direction in the process from the air inlet opening state to the air inlet closing state, the first roller shutter 2, the first filter screen 3, the second roller shutter 4 and the second filter screen 5 are simultaneously disposed at the air inlet, the first roller shutter 2 and the second filter screen 5 are opposite, and the second roller shutter 4 is opposite to the first filter screen 3, although the air inlet can be closed at this time, a filter screen is disposed at a position outside the air inlet, so that dust is easily deposited on the filter screen. Therefore, in order to avoid this, the power source drives the belt 1 to rotate only 120 ° in the first direction in the process from the intake opening state to the intake closing state.
In addition, the air outlet opening and closing mechanism provided by the embodiment can be further arranged at the air outlet and used for controlling the opening and closing of the air outlet of the air conditioner.
It should be noted that, in the present embodiment, the number of the driving belts 1 is two, the two driving belts 1 are disposed in parallel, and the first roller shutter 2, the second roller shutter 4, the first filter screen 3, and the second filter screen 5 are all installed between the two driving belts 1.
An alternative implementation of this embodiment is as follows: the power source includes a motor 8, a driving roller 9 and a driven roller 10, wherein:
the motor 8 is mounted to the first housing 11, and the motor 8 is connected to a power source, so that the motor 8 is supplied with power from the power source to drive the motor 8 to operate. Of course, when the opening and closing mechanism is installed at the air inlet of the air conditioner, the first seat 11 is installed in the casing of the air conditioner, and the power supply is a controller connected with the mains supply and provided with the air conditioner.
As shown in fig. 1 and 2, the driving roller 9 is provided with a driving gear 91, the driving belt 1 is provided with a tooth part 100 positioned on the inner annular wall of the annular ring, the tooth part 100 is meshed with the driving gear 91, so that transmission is realized, and the first rolling curtain 2, the second rolling curtain 4, the first filter screen 3 and the second filter screen 5 can be wound on the driving roller 9. The driving roller 9 is connected to the rotation shaft of the motor 8, so that the driving roller 9 is driven to rotate by the motor 8. When the motor 8 drives the driving roller 9 to rotate, the driving gear 91 is meshed with the tooth part 100, so that the driving belt 1 is driven to rotate along the circumferential direction of the ring.
