Description

Technical Field

[0001] The invention belongs to the technical field of air conditioning, and in particular relates to an air conditioner. Background Art

[0002] During daily use, ordinary air conditioners inevitably accumulate dust and dirt on the filter. Large amounts of dust and dirt can breed harmful microorganisms such as mold and dust mites. These harmful substances will circulate indoors as the air conditioner operates, polluting the air, spreading diseases, and seriously endangering human health. In addition, long-term use of air conditioners can cause dust and other impurities to accumulate in the drain pipe, leading to drainage failure and condensate backflow, which in turn causes the air conditioner to leak. To solve these problems, users have to manually clean the filter (air inlet) and drain pipe regularly or irregularly. This method is not only time-consuming and labor-intensive, but may also cause dust to be raised during cleaning. In addition, dust accumulation on the filter increases wind resistance, reduces the air volume in and out of the air conditioner, and thus reduces the cooling and heating performance of the air conditioner and increases energy consumption. Although some related technologies have proposed a cleaning structure that can vacuum and clean the air inlet filter, the existing technology does not take into account the cleaning of the drain pipe. Summary of the Invention

[0003] Therefore, the present invention provides an air conditioner that can solve the technical problem in the prior art that the air conditioner lacks a device that can clean the air inlet filter and the drain pipe at the same time.

[0006] In some embodiments, the dust suction pipe can be driven to reciprocate along the first direction of the air inlet filter, and one end of the dust suction pipe is connected to the inner space of the dust collecting box through a hose.

[0007] In some embodiments, the air inlet filter is supported on a bracket, and the bracket includes a first hollow groove and a second hollow groove that are relatively spaced apart.

[0019] See also Figures 1 to 3As shown, according to an embodiment of the present invention, an air conditioner is provided, including a cleaning device, an air inlet filter 3, and a drain pipe 4. The cleaning device includes a dust box 11, and a dust box 12 is provided at the bottom of the dust box 11. An air pump assembly 13 is provided in the dust box 11, and the air pump assembly 13 can be controlled to suck air or blow air. The dust box 11 is connected to a dust suction pipe 21 and an air blowing pipe 22 connected to its internal space. The dust suction pipe 21 is arranged adjacent to the air inlet filter 3, and the air blowing pipe 22 is connected to the drain pipe 4. A filter element 133 is provided at the air intake of the air pump assembly 13, and the dust box 12 is located under the filter element 133 so as to collect dust and other dirt sucked in by the dust suction pipe 21. The aforementioned proximity can be specifically understood as the maximum distance that the dust suction pipe 21 should maintain to achieve dust suction and cleaning of the air inlet filter 3. In this technical solution, when the air inlet filter 3 needs to be vacuumed and cleaned, the air pump assembly 13 is controlled to suck air to form a negative pressure space between the dust suction pipe 21 and the air inlet filter 3, thereby cleaning the air inlet filter 3. When the drain pipe 4 needs to be cleaned, the air pump assembly 13 is controlled to blow air to form a positive pressure environment in the drain pipe 4, thereby using the positive pressure to eliminate blockages in the drain pipe 4 and cleaning the drain pipe 4. This achieves the dual function of cleaning the air inlet filter 3 and the drain pipe 4, and the structure is simple. In a specific embodiment, the air pump assembly 13 can be a commercially available molded product, such as a dual-purpose air pump for blowing and suction, to simplify the structural design and the difficulty of component control.

[0020] In some embodiments, a first isolation plate 131 is provided between the dust suction pipe 21 and the air pump assembly 13. The first isolation plate 131 is in a connected state when the dust suction pipe 21 cleans the air inlet filter 3, and is in a cut-off state when the air blowing pipe 22 cleans the drain pipe 4; a second isolation plate 132 is also provided between the air blowing pipe 22 and the air pump assembly 13. The second isolation plate 132 is in a cut-off state when the dust suction pipe 21 cleans the air inlet filter 3, and is in a connected state when the air blowing pipe 22 cleans the drain pipe 4. Specifically, the first isolation plate 131 and the second isolation plate 132 separate the internal space of the dust box 11 into a separate accommodating chamber, and the air pump assembly 13 is installed in the accommodating chamber. The flow direction selection of the negative pressure airflow and the positive pressure airflow of the air pump assembly 13 is realized by the on-off control of the first isolation plate 131 and the second isolation plate 132. The structure is simple and compact, and the aforementioned filter element 133 can be arranged on the side of the first isolation plate 131 facing the dust box 12.

[0021] It can be understood that the wall of the dust suction pipe 21 has suction holes arranged at intervals along the axial and circumferential directions of the wall. In this way, the dust suction pipe 21 can be controlled to rotate around the center line of the pipe without reducing the dust collection effect. In a preferred embodiment, the dust suction pipe 21 can be driven to reciprocate along the first direction of the air inlet filter 3. One end of the dust suction pipe 21 is connected to the internal space of the dust collection box 11 through a hose 211. The aforementioned first direction can be specifically determined according to the actual installation environment of the air inlet filter 3. For example, it can be the height direction of the air inlet filter 3 or the width direction. In this technical solution, the dust suction pipe 21 is driven to reciprocate along the first direction, which can simplify the structural design of the dust suction pipe 21. The purpose of dust collection of the air inlet filter 3 within a larger area can be achieved through a smaller dust suction pipe 21.

[0022] In some embodiments, the air inlet filter 3 is supported on a bracket (not marked in the figure), and the bracket includes a first hollow groove 51 and a second hollow groove 52 that are relatively spaced apart. A first rack 214 is respectively provided in the first hollow groove 51 and the second hollow groove 52. The two ends of the dust suction pipe 21 respectively have a first gear 212, and the first gear 212 is meshed with the first rack 214. The other end of the dust suction pipe 21 is connected to a first rotary motor 213, and the first rotary motor 213 can drive the dust suction pipe 21 to rotate around its center line. In this way, by controlling the forward and reverse rotation of the first rotary motor 213 and the meshing relationship between the first gear 212 and the first rack 214, the linear reciprocating motion of the dust suction pipe 21 is driven, and the structure is compact and simple. It should be noted that when the aforementioned hose 211 is flexible enough to be deformed, the hose 211 and the dust suction tube 21 can be fixedly connected. However, when a larger deformation amount is required, the hose 211 may be damaged. At this time, the hose 211 and the dust suction tube 21 can be rotated to connect, but attention should be paid to the design of the sealing structure.

[0023] In some embodiments, the air conditioner further includes an evaporator (not shown in the figure), the dust suction pipe 21 is located on the side of the air inlet filter 3 away from the evaporator, and a dust cover assembly is provided on the side of the air inlet filter 3 close to the evaporator, the dust cover assembly includes a dust cover 61, the dust cover 61 has a dust-proof position that blocks the flow area of the air inlet filter 3 and an air inlet position that allows the air inlet filter 3 to flow through, the dust cover 61 can be driven to switch between the dust-proof position and the air inlet position. Specifically, when the dust suction pipe 21 reciprocates to vacuum the air inlet filter 3, the area farther away from the dust suction pipe 21 is disturbed by the dust suction pipe 21 due to the lack of the necessary negative pressure dust suction space. The dust on the air inlet filter 3 will be shaken off and easily attached to the evaporator arranged adjacent to it. At this time, during the vacuuming operation, the dust cover 61 can be placed in the dust-proof position to block and protect the evaporator, and when the vacuuming operation is not performed, the dust cover 61 is placed in the air inlet position so as not to hinder the air intake of the air conditioner.

[0024] The bracket further includes a third hollow groove 53 and a fourth hollow groove 54 that are spaced apart from each other. In a specific embodiment, Figure 3 As shown, the third hollow groove 53 is arranged opposite to the first hollow groove 51, and the fourth hollow groove 54 is arranged opposite to the second hollow groove 52. The dust cover 61 is wound on the reel 62, and the two ends of the reel 62 have a second gear 63 respectively. The third hollow groove 53 and the fourth hollow groove 54 are respectively provided with a second rack 64, and the second gear 63 is engaged with the second rack 64. One end of the reel 62 is connected to the second rotary motor 65, and the second rotary motor 65 can drive the reel 62 to rotate around its axial center line. In this way, by controlling the forward and reverse rotation of the second rotary motor 65, the dust cover 61 can be wound and unwound, thereby realizing the flexible switching of its dustproof position and air inlet position.

[0025] See Figure 2 As shown, the air conditioner also includes a water collecting pan 7 under the evaporator, the drain pipe 4 is connected to the drain outlet of the water collecting pan 7, and a valve plate 41 is provided at the drain outlet. The valve plate 41 has a sealing position for sealing the drain outlet and a connecting position for allowing the drain outlet to drain. The valve plate 41 switches from the connecting position to the sealing position under the action of its own weight. When the drain pipe 4 drains water, the flow pressure of the condensed water will push the valve plate 41 open to place it in the connecting position. When the drain pipe 4 does not drain water, the valve plate is in the sealing position under the action of its own weight, effectively preventing external debris and mosquitoes from entering the interior of the air conditioner through the drain outlet.

[0026] In some embodiments, the top of the valve plate 41 is hinged to the drain outlet or drain pipe 4 through a rotating shaft 42. When the valve plate 41 is in a sealed position, and from the top to the bottom of the valve plate 41, the position of the valve plate 41 becomes increasingly farther away from the drain outlet so that the valve plate 41 is tilted relative to the drain outlet. In this way, when the air pump assembly 13 is controlled to blow positive pressure airflow into the blowing pipe 22, that is, the drain pipe 4, this part of the positive pressure airflow can be prevented from pushing the valve plate 41 open and entering the interior of the air conditioner to cause pollution, thereby reducing the cleaning effect of the drain pipe 4.

[0027] The dust box 12 is connected to the dust box 11 by sliding and pulling. After enough dust accumulates in the dust box 12, the user can pull it out of the dust box 11 and perform necessary cleaning, which is convenient for user operation.
