Detailed Description
Exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the present invention are shown in the drawings, it should be understood that the present invention may be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.
Referring to fig. 1-6, an embodiment of the present invention provides a filter device that may include two bases 1, a rail 2, a filter assembly 3, a motor drive assembly 4, and a cleaning assembly 5, wherein:
the guide rail 2 is installed between the two bases 1, the filtering component 3 is connected to the guide rail 2 in a sliding mode, and an air inlet of the air conditioner is covered, so that air entering the air conditioner is filtered. The motor driving assembly 4 is mounted on the base 1 and meshed with the filtering assembly 3, so as to drive the filtering assembly 3 to reciprocate along the upper end face and the lower end face of the guide rail 2 through a driving motor 41 of the motor driving assembly 4. The cleaning component 5 is fixed on the base 1, and cleans the filter component 3 bypassing the base 1 when the filter component 3 reciprocates.
In the embodiment of the invention, the two bases 1 can be fixed in the shell of the air conditioner and distributed on two sides of the air inlet of the air conditioner. The guide rail 2 is installed between the two bases 1 and can be opposite to the air inlet, so that a movement track for the filter assembly 3 to move can be formed through the guide rail 2. Wherein the filter assembly 3 may be made of a flexible material, which is engageable with the motor drive assembly 4 and capable of bypassing the base 1, extending from one end face of the guide rail 2 to the other end face of the guide rail 2. For example, the upper end surface 21 of the guide rail 2 may extend to the lower end surface 22 of the guide rail 2, or the lower end surface 22 of the guide rail 2 may extend to the upper end surface 21 of the guide rail 2. The motor driving assembly 4 is configured to provide a driving force to the filter assembly 3, so as to drive the filter assembly 3 to move on the guide rail 2 when the driving motor 41 rotates, so that the cleaning assembly 5 installed on the base 1 can clean the filter assembly 3 when the filter assembly 3 bypasses the base 1. From this, can not carry out the dismouting of filter module 3 under the condition for driving motor 41 is rotatory, carries out the self-cleaning of filter module 3, when improving the clean efficiency of filter module 3, can also improve the clean convenience and the product suitability of filter module 3, is favorable to improving user experience and feels.
In an alternative embodiment of the invention, referring to fig. 1 and 2, when the number of the filter assembly 3, the motor driving assembly 4 and the cleaning assembly 5 is two, one motor driving assembly 4 and one cleaning assembly 5 are mounted on each base 1. Wherein, two filter components 3 are arranged in parallel on the guide rail 2, and the moving directions of the two filter components 3 on the guide rail 2 are opposite.
In the embodiment of the present invention, two filter assemblies 3 are arranged in parallel on the guide rail 2, that is, distributed on the left and right sides of the guide rail 2. Thus, when the two motor driving assemblies 4 respectively drive the two filter assemblies 3 to move along the guide rail 2, the moving directions of the two filter assemblies 3 are opposite. For example, two filter assemblies 3 may be in contact at the centre of the guide rail 2, together forming a cover for the air intake of the air conditioner. When the self-cleaning of the filter assembly 3 is required, the two driving motors 41 rotate according to different rotation directions, so that the filter assembly 3 moves back to back along the guide rail 2, namely, all moves towards the direction of the base 1, the filter assembly 3 can bypass the base 1, and the cleaning assembly 5 can clean the whole filter assembly 3. In addition, the number of the filter assemblies 3, the motor driving assemblies 4 and the cleaning assemblies 5 is increased, so that the cleaning time of the filter assemblies 3 can be shortened, and the cleaning efficiency of the filter assemblies 3 is greatly improved.
In one example, the initial positions of two of the filter assemblies 3 may be located at the upper end surface 21 or the lower end surface 22 of the guide rail 2, and the two filter assemblies 3 are in contact at the center of the guide rail 2. After self-cleaning, the end positions of the two filter assemblies 3 may be located at the lower end face 22 or the upper end face 21 of the guide rail 2, and the two filter assemblies 3 are in contact at the center of the guide rail 2.
In another example, referring to fig. 3 and 4, the initial positions of the two filter assemblies 3 may be located at the upper end surface 21 or the lower end surface 22 of the guide rail 2, and the two filter assemblies 3 are contacted at the center of the guide rail 2. After self-cleaning, the end positions of the two filter assemblies 3 may be located at the upper end face 21 or the lower end face 22 of the guide rail 2, and the two filter assemblies 3 are in contact at the center of the guide rail 2. That is, during self-cleaning, the filter assembly 3 moves from the upper end surface 21 or the lower end surface 22 of the guide rail 2, bypasses the base 1, and is cleaned for the first time by the filter assembly 3. When the two filter assemblies 3 reach the lower end face 22 or the upper end face 21 of the guide rail 2 and contact is formed, the two driving motors 41 stop working first, and then the two driving motors 41 change the rotation direction, so that the filter assemblies 3 start to move from the lower end face 22 or the upper end face 21 of the guide rail 2, bypass the base 1, pass through the cleaning of the second filter assemblies 3, and reach the upper end face 21 or the lower end face 22 of the guide rail 2 when the two filter assemblies 3 reach contact (namely return to the initial position), and the two driving motors 41 stop working. At this point the self-cleaning is ended. Thus, when the self-cleaning is performed once, the filter assembly 3 is correspondingly cleaned twice, and the cleanliness of the filter assembly 3 can be improved.
In an alternative embodiment of the invention, referring to fig. 3, the filter assembly 3 includes a filter screen 31, a first engaging tooth 311 engaged with the motor driving assembly 4 is disposed on the filter screen 31, and the motor driving assembly 4 drives the filter screen 31 to reciprocate along the upper and lower end surfaces of the guide rail 2, so that the cleaning assembly 5 cleans the filter screen 31 bypassing the base 1.
In this embodiment of the present invention, as a preference of the filter assembly 3, the filter assembly 3 may be a filter screen 31, and the first engaging teeth 311 may be disposed at an edge of the filter screen 31, so that the first engaging teeth 311 engage with the motor driving assembly 4, so as to drive the filter screen 31 to move along the guide rail 2 when the motor rotates. Correspondingly, the filter mesh 31 can be regarded as a gear belt. When the filter assembly 3 is one, the length of the filter mesh 31 needs to be greater than the length of the guide rail 2, so that a part of the filter mesh 31 can extend to the other end surface of the guide rail 2 around the base 1.
In an alternative embodiment of the invention, referring to fig. 1, 2 and 4, the filter assembly 3 further includes a roller shutter 32, and the roller shutter 32 and the filter screen 31 are arranged in parallel on the guide rail 2. The roller shutter 32 is provided with a second engaging tooth 321 engaged with the motor driving assembly 4, so that the motor driving assembly 4 drives the roller shutter 32 to reciprocate along the upper end surface and the lower end surface of the guide rail 2, so that the cleaning assembly 5 cleans the roller shutter 32 bypassing the base 1. When the roller shutter 32 moves along the guide rail 2 to the air inlet, the air inlet is sealed.
In the embodiment of the present invention, the roller shutter 32 is made of a flexible material, and correspondingly, in order to facilitate the processing of the filter assembly 3, the connection stability between the filter screen 31 and the roller shutter 32 is improved, and the filter screen 31 and the roller shutter 32 are in an integrated structure. The juxtaposition may be understood as the rolling screen 32 and the filter screen 31 being arranged in sequence along the length direction of the guide rail 2. Wherein the roller shutter 32 is used for closing an air inlet of the air conditioner. Therefore, the air conditioner does not need to be additionally provided with a wind shield, and the structure of the air conditioner can be simplified.
In an example, when the air conditioner stops working, the driving motor 41 is started to rotate, so that the filter screen 31 positioned on the air inlet is driven to move, and because the filter screen 31 and the roller shutter 32 are arranged in parallel, when the filter screen 31 and the roller shutter 32 simultaneously run from one end face to the other end face of the guide rail 2, the relative positions of the roller shutter 32 and the filter screen 31 are interchanged, so that the roller shutter 32 seals the air inlet.
When the air conditioner starts to work, the driving motor 41 can be started to rotate, so that the roller shutter 32 positioned on the air inlet is driven to move, and when the filter screen 31 and the roller shutter 32 simultaneously run from one end face to the other end face of the guide rail 2, the relative positions of the roller shutter 32 and the filter screen 31 are exchanged, so that the filter screen 31 covers the air inlet, and air entering the air inlet of the air conditioner is filtered.
In an alternative embodiment of the invention, referring to fig. 6, the motor-driven assembly 4 may further include a drum 42, a first gear 43, and a transmission gear set 44, wherein:
the drum 42 is rotatably connected to the base 1 and is provided with third engagement teeth 421 engaged with the filter assembly 3. The third engaging tooth 421 may be integrally formed with the drum 42, and in another example, the drum 42 may further include a gear portion, that is, a gear portion formed by coaxially fixing a gear with the body of the drum 42, and the gear on the gear portion is used as the third engaging tooth 421. The first gear 43 is coaxially fixed with the roller 42, the transmission gear set 44 is meshed with the first gear 43, wherein the driving motor 41 is fixed on the base 1, and an output shaft of the driving motor 41 is in transmission connection with the transmission gear set 44 so as to drive the roller 42 to rotate.
In the embodiment of the invention, the rotary connection can be realized by adopting a bearing and the like, wherein the filter assembly 3 bypasses the roller 42 and extends to the other end face of the guide rail 2, so that the reciprocating movement of the filter assembly 3 can be realized. That is, the drum 42 moves the filter assembly 3 engaged therewith along the guide rail 2 by the rotation force of the driving motor 41. In which a rotating roller for facilitating the movement of the filter assembly 3 may be appropriately provided on the guide rail 2, which is not excessively limited. Wherein, the guide rail 2 is used for limiting or pressing the filter assembly 3, so that the tension force between the filter assembly 3 and the roller 42 meets the moving force requirement of the filter assembly 3.
The drive gear set 44 may include at least one drive gear. When the number of the transmission gears of the transmission gear set 44 is one, the output shaft of the driving motor 41 is coaxially fixed with the transmission gears; when the number of the transmission gears is at least two, the output shaft of the driving motor 41 is coaxially fixed with one of the transmission gears, and the transmission gears except for the transmission gear are rotatably connected to the base 1. One skilled in the art can comprehensively select the number of the transmission gears corresponding to the transmission gear set 44 according to the type of the driving motor 41 and the transmission ratio of the transmission gears.
For example, the driving gear set 44 may include a first driving gear 441 and a second driving gear 442 engaged with the first driving gear 441, the first driving gear 441 being engaged with the first gear 43, the second driving gear 442 being coaxially fixed with the output shaft of the driving motor 41. Wherein the diameter of the first transmission gear 441 is larger than that of the second transmission gear 442, so that the rotation speed of the first gear 43 can be reduced by the first transmission gear 441, and the moving speed of the filter assembly 3 on the guide rail 2 is suitable, so that the filter assembly 3 can be cleaned by the cleaning assembly 5.
In an alternative embodiment of the invention, referring to fig. 5, the cleaning assembly 5 may include a first brush 51 and a dust box 52, wherein the first brush 51 is fixed to the base 1 to clean an end surface of the filter assembly 3 remote from the guide rail 2. The dust box 52 is installed below the first brush 51 to receive foreign matters falling from the first brush 51.
