Detailed Description
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 clearly and completely described below with reference to specific embodiments of the present invention and corresponding drawings. It will be apparent that the described embodiments are only some, but not all, embodiments of the invention. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
It should be noted that the terms "first," "second," and the like in the description and the claims of the present invention and the above figures are used for distinguishing between similar objects and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used may be interchanged where appropriate such that the embodiments of the invention described herein may be implemented in sequences other than those illustrated or otherwise described herein.
As shown in fig. 1 and 2, a dust-proof structure of a heat exchanger, the heat exchanger 1 having a windward side 11 and a leeward side 12, air being able to flow from one side of the windward side 11 to one side of the leeward side 12 through the heat exchanger 1, the dust-proof structure comprising: a filter device 2, a cleaning device 3 and a drive device (which may be a motor) 4. The driving device 4 is connected to the filtering device 2 for driving the filtering device 2 between a first position on the windward side 11 and a second position on the leeward side 12. The cleaning device 3 is arranged on the heat exchanger 1, and the cleaning device 3 can be brought into abutment on the filter device 2 for cleaning the filter device 2 when the filter device 2 is switched between the first position and the second position.
In order to facilitate understanding, the working principle of the dustproof structure of the heat exchanger is specifically described by combining with an air conditioner, wherein the heat exchanger 1 can be a condenser in an outdoor unit of the air conditioner, in specific use, a fan 5 is arranged on one side of a leeward side 12 of the heat exchanger (condenser) 1, and when the air conditioner is in normal operation, the fan 5 blows air in a direction opposite to the heat exchanger 1, negative pressure can be formed on two sides of the heat exchanger 1, namely, air can flow from one side of a windward side 11 to one side of the leeward side 12 through the heat exchanger 1. The filter device 2 is located at a first position on the windward side 11 to filter the air flowing to the heat exchanger 1, so that dust and other floaters are adsorbed to the filter device 2 and prevented from being adsorbed to the surface of the heat exchanger 1. When the air conditioner stops working, the driving device 4 drives the filtering device 2 to move to the second position on one side of the leeward side 12, and in the moving process, the cleaning device 3 can be abutted on the filtering device 2 and can clean dust adsorbed on the filtering device 2 or the dust is in a loose state on the filtering device 2. The condenser in the air conditioner is generally L-shaped, and the cleaning device 3 may be provided at an end of a short side of the condenser, but is not limited thereto, and may be connected to a housing of the air conditioner. It should be noted that when the filter device 2 moves to the second position on the leeward side 12, the filter device 2 is located between the leeward side 12 and the fan 5, and the fan 5 continues to rotate at this time, so that dust on the filter device 2 in a loose state can be sucked away, and the purpose of thoroughly cleaning the filter device 2 is achieved. After the dust in a loose state on the filter device 2 is sucked away, the fan 5 stops rotating, and at this time, the driving device 4 drives the filter device 2 to move back to the first position, so that preparation for the next dust-proof work is performed.
By adopting the technical scheme, dust and other floaters can be prevented from being adsorbed on the surface of the heat exchanger, dust is prevented from being accumulated on the filter device 2 to influence the flow rate of air flowing through the heat exchanger, and then the heat exchange effect of the heat exchanger is prevented from being influenced due to the fact that the flow rate of the air flowing through the heat exchanger is reduced.
Specifically, when the filter device 2 is in the first position, the filter device 2 is flush with both ends of the heat exchanger 1 or beyond both ends of the heat exchanger 1. This can effectively shield the windward side 11 of the heat exchanger 1 from the filter device 2, and further improve the filtering effect of the air flowing to the heat exchanger 1.
Further, the driving device 4 is connected to the cleaning device 3 for driving the cleaning device 3 to rotate. This enables the filter device 2 to be cleaned by the rotation of the cleaning device 3, which improves the cleaning effect.
As an alternative embodiment, as shown in fig. 1, it further comprises an upper rail 6 and/or a lower rail 7, and the filter device 2 is connected to the upper rail 6 and/or the lower rail 7 and is capable of translating movement along the upper rail 6 and/or the lower rail 7 between a first position and a second position. When the dustproof structure of the heat exchanger is applied to an air conditioner, the upper guide rail 6 and/or the lower guide rail 7 may be fixedly connected to the inner wall of the air conditioner case.
Preferably, a first travel switch (not shown) is provided on the upper rail 6 or the lower rail 7; the first travel switch is electrically connected to the driving device 4, and can be triggered when the filter device 2 moves to the first position, so as to control the driving device 4 to stop working. This allows the movement of the filter device 2 to the first position to be controlled by the first travel switch to stop the movement, thereby ensuring the accuracy of the movement of the filter device 2 to the first position.
Preferably, a second travel switch (not shown) is provided on the upper rail 6 or the lower rail 7; the second travel switch is electrically connected with the driving device 4, and can be triggered when the filtering device 2 moves to the second position, so as to control the driving device 4 to stop working. In this way, the second travel switch can be used to control the filter device 2 to stop moving when the filter device 2 moves to the second position, so that the accuracy of the movement of the filter device 2 to the second position is ensured.

Preferably, as shown in fig. 5, a first guide groove 61 is provided on the upper rail 6 and/or a second guide groove (not shown) is provided on the lower rail 7, and when the first guide groove 61 and the second guide groove exist at the same time, the first guide groove 61 and the second guide groove are symmetrical to each other. The filter device 2 comprises an upper guide 23 and/or a lower guide 24, the upper guide 23 being connected to the upper end of the frame 21 and/or the lower guide 24 being connected to the lower end of the frame 21, the upper guide 23 extending into the first guide slot 61 and being movable in the first guide slot 61 and/or the lower guide 24 extending into the second guide slot and being movable in the second guide slot.
Specifically, the first guide groove 61 includes a first guide section a611, a first curved section 612, and a first guide section b613.

Specifically, as shown in fig. 6, the cleaning device 3 includes a cylindrical brush body 31 and bristles 32 disposed on a surface of the brush body 31, and the cleaning device 3 is disposed at a position corresponding to the first curved section 612 and/or the second curved section.

Preferably, as shown in fig. 7, the first curved section 612 and/or the second curved section has a circular arc shape coaxial with the brush body 31; when the frame 21 moves along the first bending section 612 and/or the second bending section, the bending radius of the filter screen 22 is R1, the distance between the end of the brush 32 away from the brush body 31 and the axis of the brush body 31 is R2, wherein R1 < R2, and when the brush 32 abuts against the filter screen 22, the end of the brush 32 away from the brush body can protrude from the mesh of the filter screen 22. This allows the dust adsorbed on the mesh of the filter screen 22 to be pushed off or loosened by the brush hair 32, thereby improving the cleaning effect.
