Description

Technical Field

[0001] The present application relates to the technical field of air-conditioning equipment, for example, to a dust-proof mechanism for an air-conditioner, an air-conditioner indoor unit and an air-conditioner. Background Art

[0002] Most wall-mounted air conditioners have open air inlets. When the air conditioner is not in use, dust is easily deposited at the air inlet. When it is used again, dust can easily enter the interior of the air conditioner.

[0003] In the related art, an air inlet dust prevention device is disclosed. The air inlet dust prevention device is arranged at the air inlet of the electrical equipment. The dust prevention device includes a bracket and a baffle. The baffle includes an open state and a closed state. Both ends of the baffle are rotatably arranged at the opening at the top of the bracket. The baffle is controlled to switch between the open state and the closed state to open or close the opening at the top of the bracket; when the air conditioner is in the off state, the air inlet is closed, so that dust cannot enter the air conditioner, reducing the number of times the air conditioner needs to be cleaned.

[0004] The following problems exist in the publicly available implementation process:

[0005] By setting a baffle that can be opened or closed, the air inlet is closed when the air conditioner is turned off, thereby shielding the air inlet. However, during the use of the air conditioner, dust will still enter the air conditioner through the air inlet, resulting in the need to frequently clean the indoor heat exchanger of the air conditioner.

[0081] In this embodiment, a first transmission structure 254 and a second transmission structure 255 are respectively disposed on both sides of the first roller body 220 and the second roller body 230 to improve the synchronization and stability of the rotation of the first roller body 220 and the second roller body 230 .

[0082] Optionally, the first transmission structure 254 and the second transmission structure 255 have the same structure.

[0083] Optionally, combined Figure 7 As shown, the curtain 210 includes two parts. One part is a permeable filter curtain 214, which is used in the scene where the air conditioner is turned on. When the indoor air passes through the filter curtain 214, it does not block the fluidity of the air, but can filter larger pollutant particles such as hair scraps from entering the air conditioner. One part is an airtight dustproof curtain 212, which is used in the scene where the air conditioner is not used for a long time. It can cover the air inlet 102 of the air conditioner to prevent dust from entering the interior of the air conditioner and affecting the cleaning of the interior of the air conditioner. A complete curtain 210 is formed by sewing the middle of two different types of curtains 210, and is wound around the first roller body 220 and the second roller body 230.

[0084] Optionally, the dustproof curtain 212 is made of polyester. The polyester material has high flexibility and is easy to clean and maintain.

[0085] Optionally, the filter curtain 214 includes a filter cloth, an outer frame and a skeleton, the skeleton is arranged in the outer frame, and the skeleton is connected to the outer frame. It is estimated that the space in the outer frame is divided into a plurality of subspaces. The filter cloth is connected to the outer frame and the skeleton, and is covered in a plurality of subspaces. By setting the skeleton, the filter is supported, thereby improving the flatness of the filter curtain 214. Optionally, the outer frame is made of the same material as the dust curtain 212 for easy processing. The skeleton is made of plastic, and the skeleton is in the shape of an elongated strip and has a certain degree of flexibility to facilitate winding on the first roller body 220 or the second roller body 230.

[0086] In some embodiments, in combination Figure 3 , Figure 5 , Figure 8 , Fig. 9 As shown, an air conditioner indoor unit 1 is provided, comprising: a housing 100 including an air inlet 102 , and a dustproof mechanism 200 as described in any one of the above items, the dustproof mechanism 200 being installed at the air inlet 102 .

[0087] Combination Figure 5 and Figure 6 As shown, the air conditioner indoor unit 1 provided by the present disclosure includes a housing 100 and the dustproof mechanism described in any of the above embodiments. The housing 100 includes an air inlet 102, and the dustproof mechanism 200 is arranged in the housing 100 and located at the air inlet 102. By setting the dustproof mechanism 200, the driving component 240 is controlled to work according to the operating state of the air conditioner. When the air conditioner is in a stopped state, the air inlet 102 is shielded by the dustproof curtain 212 in the curtain 210. When the air conditioner is in a working state, the filter curtain 214 in the curtain 210 is covered on the air inlet 102 to filter the gas entering the air conditioner. Through the dustproof mechanism 200 provided by the present disclosure, the amount of dust entering can be reduced when the air conditioner is in a stopped state and a working state, thereby improving the dustproof effect and reducing the cleaning frequency of the indoor heat exchanger in the air conditioner indoor unit 1.

[0088] Optionally, combined Fig.11 As shown, the air conditioner indoor unit 1 further includes a stopper 104 . The stopper 104 is disposed on the housing 100 and is located at at least one side of the air inlet 102 . A stopper groove 106 is formed between the stopper 104 and the housing 100 , and the curtain 210 passes through the stopper groove 106 .

[0089] In this embodiment, a limiting member 104 is provided on the outer wall of the housing 100, and the limiting member 104 is located on one side or two opposite sides of the air inlet 102. A limiting groove 106 is formed between the limiting member 104 and the outer wall of the housing 100, and the curtain 210 passes through the limiting groove 106. The limiting member 104 is provided to limit the thickness direction of the curtain 210, thereby improving the fit between the curtain 210 and the air inlet 102 and improving the dustproof effect.

[0090] In some embodiments, the limiting members 104 are respectively provided on opposite sides of the air inlet 102, so that the curtain 210 extends from the first roller body 220, passes through the limiting groove 106 provided on one side, passes through the air inlet 102, and then passes through the limiting groove 106 on the other side of the air inlet 102, and is connected to the second roller body 230. By providing the limiting members 104 on opposite sides of the air inlet 102, the height of the curtain 210 to the air inlet 102 can be adjusted to improve the fit between the curtain 210 and the air inlet 102, so as to improve the dust prevention and filtering effects.

[0091] Optionally, the housing 100 further includes a housing chamber, an indoor heat exchanger, and an indoor fan, and the indoor heat exchanger and the indoor fan are both arranged in the housing chamber. The housing chamber is connected to the air inlet 102. Under the action of the indoor fan, the external air enters the housing chamber from the air inlet 102, enters the indoor heat exchanger, and is discharged through the air supply port of the housing 100. By arranging a dustproof mechanism 200 at the air inlet 102, it is possible to reduce the entry of external dust into the housing chamber, thereby reducing the dust accumulation of the indoor heat exchanger and reducing the frequency of cleaning the indoor heat exchanger.

[0092] Furthermore, the dustproof mechanism 200 is arranged on the outer wall of the housing 100, and is located outside the accommodating cavity. By arranging the dustproof mechanism 200 outside the accommodating cavity, that is, the outer wall of the housing 100, the space occupancy rate of the inner wall of the accommodating cavity is reduced, the structural setting of the internal components of the air conditioner indoor unit 1 is avoided, the modified part of the indoor unit is reduced, and the production cost is reduced.

[0093] Optionally, the air conditioner indoor unit 1 further includes a flow sensor. The flow sensor is disposed at the air inlet 102. The flow sensor is used to detect the flow information of the gas passing through the air inlet 102. The dirtiness of the filter curtain 214 is determined by the flow information detected by the flow sensor. When the flow information is less than the set value, it indicates that the filter curtain 214 is blocked to a certain extent, and a reminder message is issued to remind the user to clean the curtain 210.

[0094] Optionally, combined Figure 3As shown, the first roller body 220 and the second roller body 230 are distributed on opposite sides of the air inlet 102 along the width direction of the air inlet 102. The first roller body 220 and the second roller body 230 both extend along the length direction of the air inlet 102. The curtain 210 is wound around the first roller body 220 and the second roller body 230. The width of the curtain 210 is greater than the length of the air inlet 102 so that it can cover the entire air inlet 102, thereby improving the dust prevention and filtering effects. The dust curtain 212 and the filter curtain 214 are arranged along the width direction of the air inlet 102. Driven by the drive assembly 240, the curtain 210 can reciprocate along the width direction of the air inlet 102, thereby adjusting the relative position relationship between the dust curtain 212 and the filter curtain 214 and the air inlet 102.

[0095] Optionally, the winding direction of the curtain 210 wound around the first roller 220 is opposite to the winding direction of the curtain 210 wound around the second roller 230. In this way, when the driving assembly 240 is started, the curtain 210 on the first roller 220 is in the rolling state, and the curtain 210 on the second roller 230 is in the unwinding state; or, the curtain 210 on the first roller 220 is in the unwinding state, and the curtain 210 on the second roller 230 is in the rolling state. Further, along the height direction of the first support body 270 and the second support body 280, the part of the curtain 210 corresponding to the air inlet 102 is located below the first roller 220 and the second roller 230 to improve the fit with the air inlet 102.

[0096] Specifically, when the air conditioner is not used for a long time, the driving motor is controlled to rotate, and the driving motor drives the second roller 230 to rotate in the first direction, and at the same time drives the first roller 220 to rotate in the first direction synchronously through the transmission gear belt 253. At this time, the filter curtain 214 is wound on the second roller 230, and the dust curtain 212 previously wound on the first roller 220 is released. The curtain 210 passes through the two limit grooves 106 on the housing 100, and when the dust curtain 212 completely covers the air inlet 102, the motor stops rotating.

[0097] In the scenario where air conditioning is required, the driving motor is controlled to rotate, and the driving motor drives the second roller 230 to rotate in the second direction, and at the same time drives the first roller 220 to rotate synchronously in the second direction through the transmission gear belt 253, and the dust curtain 212 is wound around the first roller 220, and the filter curtain 214 previously wound around the second roller 230 is released. The curtain 210 passes through the two limiting grooves 106 on the housing 100, and when the filter curtain 214 completely covers the air inlet 102, the motor stops rotating.

[0098] In some embodiments, an air conditioner is provided, comprising: the dust prevention mechanism 200 as described in any one of the above items, or the indoor unit as described in the above items.

[0099] The air conditioner provided by the embodiment of the present disclosure includes the dustproof mechanism 200 as described in any of the above embodiments or the indoor unit as described in any of the above embodiments. By adopting the dustproof mechanism 200 described in any of the above schemes, the driving component 240 is controlled to work according to the operating state of the air conditioner. When the air conditioner is in a stopped state, the dustproof curtain 212 in the curtain 210 is used to block the air inlet 102. When the air conditioner is in a working state, the filter curtain 214 in the curtain 210 is used to cover the air inlet 102 to filter the gas entering the air conditioner. Through the dustproof mechanism 200 provided by the present disclosure, the amount of dust entering can be reduced when the air conditioner is in a stopped state and a working state, thereby improving the dustproof effect and reducing the cleaning frequency of the indoor heat exchanger in the air conditioner indoor unit 1.
