Next, with reference to the drawings, a fresh air part 200 and an air processing apparatus 1000 having the same according to an embodiment of the present invention are described. According to the utility model discloses air treatment device 1000 can be for air conditioner indoor unit A or air sterilizing machine etc. and include outward appearance casing 100 and according to the utility model discloses new trend part 200. According to the embodiment of the present invention, as shown in fig. 1 to 3, the air conditioner indoor unit a may include: air conditioner shell A1, fan part 300, heat transfer part 400 and according to the utility model discloses new trend part 200 of embodiment. Here, it can be understood that when the air processing apparatus 1000 is an air conditioner indoor unit a, the air conditioner casing a1 is the appearance casing 100 of the air processing apparatus 1000.

As shown in fig. 4 and 5, the fresh air component 200 may include a fresh air housing 1, a fresh air blower 2, and a purification device 3. An air inlet cavity 11, a fan cavity 12 and an air outlet cavity 13 which are sequentially communicated along the airflow flowing direction are formed in the fresh air shell 1, and with reference to fig. 6, a fresh air inlet 14 communicated with the air inlet cavity 11 and a fresh air outlet 15 communicated with the air outlet cavity 13 are formed in the fresh air shell 1. Referring to fig. 3, the fresh air fan 2 includes a fresh air wheel 21 disposed in the fan cavity 12. Referring to fig. 4, the purifying device 3 includes a purifying core 31 disposed in the air inlet chamber 11. Therefore, as shown in fig. 3-5, when the fresh air fan 2 is in operation, fresh air can enter the air inlet cavity 11 through the fresh air inlet 14, flow into the fan cavity 12 after being purified by the purification core 31, and then flow into the air outlet cavity 13 to be discharged from the fresh air outlet 15.

As shown in fig. 4, in the embodiment of the present invention, the windward surface 311 of the purification core 31 has a curved surface structure. That is, one side surface (i.e. the windward side 311) of the air flow entering the purifying core 31 is a curved surface structure, and it should be noted herein that the windward side 311 of the purifying core 31 is not required to be a continuous surface, and may be a fitting curved surface composed of multiple points, for example, which is determined according to the specific material of the purifying core 31, for example, the purifying core 31 may include a common filter screen, a high efficiency air filter core (i.e. HEPA), IPD, and the like. This can increase the effective purification area of purification core 31, thereby increasing the purification efficiency of purification core 31.

In some embodiments of the present invention, as shown in fig. 3 and 4, windward surface 311 of purification core 31 (i.e., a side surface of purification core 31 where airflow enters) is disposed toward fresh air inlet 14, and leeward surface 312 of purification core 31 (i.e., a side surface of purification core 31 where airflow exits) is disposed toward air inlet 121 of fan cavity 12. Therefore, the airflow flows from the fresh air inlet 14 to the purification core body 31, and then flows from the purification core body 31 to the air inlet 121 of the fan cavity 12, so that the whole flow path is short, the number of turns is small, the flow wind resistance is small, the air volume is large, the noise is low, and the airflow flows more smoothly.

For example, in the specific example shown in fig. 3 and 4, the fresh air wheel 21 may be a centrifugal wind wheel, the fresh air inlet 14 and the purification core 31 are located on the same axial side of the centrifugal wind wheel, and the purification core 31 is located between the centrifugal wind wheel and the fresh air inlet 14. Therefore, the airflow flows from the fresh air inlet 14 to the purification core body 31 and then flows out of the purification core body 31 to the air inlet 121 of the fan cavity 12, the airflow flows more smoothly, and the whole flow path is short, the number of turns is small, the flow wind resistance is small, the air volume is large, and the noise is low.

For example, as shown in fig. 4, the axial direction of the centrifugal wind wheel is the front-back direction, the purification core 31 and the fresh air inlet 14 are both located at the back side of the centrifugal wind wheel, the purification core 31 is located at the front side of the fresh air inlet 14, the back surface of the purification core 31 is the windward side 311, and the front surface of the purification core 31 is the leeward side 312, so that the centrifugal wind wheel and the purification core 31 are respectively located at the front side and the back side of the purification core 31. Therefore, the airflow flows from the fresh air inlet 14 to the purification core body 31 and then flows out of the purification core body 31 to the air inlet 121 of the fan cavity 12, the airflow flows more smoothly, and the whole flow path is short, the number of turns is small, the flow wind resistance is small, the air volume is large, and the noise is low.

In some embodiments of the present invention, as shown in fig. 4, windward side 311 and leeward side 312 of purification core 31 are curved structures with the same bending direction (i.e. the circle center of windward side 311 and the circle center of leeward side 312 are located on the same layer of the thickness of purification core 31, for example, the thickness direction of purification core 31 is the front-back direction, and the circle center of windward side 311 and the circle center of leeward side 312 are both located on the front side of purification core 31), so that purification core 31 is an arc plate shape with a length center line extending along an arc line. That is, the side surface (i.e., windward surface 311) of the air flow flowing into purification core 31 is of a cambered structure, and the side surface (i.e., leeward surface 312) of the air flow flowing out of purification core 31 is also of a cambered structure, and purification core 31 is made into a cambered plate shape with the length center line extending along a camber line. Therefore, the purification core body 31 is simple in structure and convenient to process. And in the embodiments described later, it is convenient to cooperate with the arc-shaped rail 17 to draw and take out smoothly and smoothly along the arc-shaped track, and the opening area of the drawing opening 16 can be reduced, and for the air treatment device 1000 with non-rectangular shape, such as circular shape, oval shape, circular-like shape, etc., it is more convenient for the user to draw and take out.

In some embodiments of the present invention, as shown in fig. 6 and 7, the fresh air casing 1 has a drawing opening 16, and the purification device 3 is configured to be suitable for entering and exiting the air inlet chamber 11 through the drawing opening 16. From this, when installation purifier 3, can push purifier 3 into new trend casing 1 through pull mouth 16, when dismantling purifier 3, can pull out purifier 3 from pull mouth 16 to can clean purifier 3, change operation such as, consequently, need not to unpack fresh air casing 1 apart and can realize purifier 3's dismouting, convenience of customers dismouting purifier 3.

In some embodiments of the present invention, as shown in fig. 6-8, the fresh air casing 1 may have an arc-shaped track 17 therein, and the purification device 3 cooperates with the arc-shaped track 17 to slide smoothly along the arc-shaped track 17 and enter and exit the air inlet chamber 11 through the drawing port 16. That is to say, when installing purifier 3, can push purifier 3 into new trend casing 1 by the pull mouth 16, and make purifier 3 slide to the operating position along arc track 17, when dismantling purifier 3, can pull purifier 3 along arc track 17, and pull out by pull mouth 16 to can clean, change etc. operation purifier 3.

Moreover, for the air treatment device 1000 with a non-rectangular shape, such as a circular shape, an oval shape, a circular-like shape, etc., the space in the indoor wall corner can be better utilized, and the adaptability is better.

It should be noted that, if the purifying device is flat, it is difficult to cooperate with the arc-shaped track, and usually it can only slide along the linear track, so that if the drawing opening is disposed at the side of the fresh air casing, a large space is needed to ensure that the purifying device can be drawn out, so that the air processing device cannot be disposed against the corner well, and the space occupied indoors is large, if it is desired to avoid this problem, the drawing opening needs to be disposed at the front side of the fresh air casing, which causes the problem that the front side of the appearance casing of the air processing device needs to be disassembled and assembled, and the disassembling and assembling of the purifying device are inconvenient, the utility model discloses an ingenious design of the arc-shaped track 17, which effectively solves the above technical problem, so that the drawing opening 16 can be disposed at the more concealed side of the fresh air casing 1, and does not need to be disposed at the front side of the fresh air casing 1, not only is convenient to disassemble and assemble, but also needs smaller disassembling and assembling space.

It should be noted that, when the fresh air casing 1 has the arc-shaped track 17 therein, the purification device 3 cooperates with the arc-shaped track 17 to slide along the arc-shaped track 17 to pass through the drawing opening 16 to enter and exit the air inlet chamber 11. Purification core 31 may or may not have the arcuate plate shape described above. For example, the length center line of the purification core 31 may also be a substantially arc-shaped wavy line, so that the purification core 31 is a substantially arc-shaped wavy plate, and at this time, the drawing opening 16 only needs to be slightly larger, and details are not described here.

Specifically, the number of the arc-shaped rails 17 is not limited, and for example, the two arc-shaped rails 17 may be spaced apart from each other in a direction perpendicular to the sliding direction of the purifying device 3, for example, when the purifying device 3 slides along the arc-shaped track in the horizontal direction, the two arc-shaped rails 17 may be fitted on both sides of the purifying device 3 in the vertical direction, so that the arc-shaped rails 17 do not affect the air intake of the purifying device 3, and the sliding stability of the purifying device 3 can be ensured. Of course, the present invention is not limited thereto, for example, in other embodiments of the present invention, the arc-shaped track 17 may also be a thin strip structure and located at the height center position of the purifying device 3 in the vertical direction, and so on.

Furthermore, it should be noted that, the utility model is not limited to this, in the other embodiments of the utility model, the arc track 17 also can not be set up in the new trend casing 1, at this moment, can set up a plurality of guide posts and so on in the new trend casing 1 to the orbit of sliding of purifying core 31 is limited to a certain extent, and perhaps, also can not set up any guide structure in the new trend casing 1, and so on.

In some embodiments of the present invention, as shown in fig. 6-8, when the fresh air component 200 is used in the air processing apparatus 1000, the fresh air casing 1 is disposed in the appearance casing 100, if the fresh air casing 1 has the drawing opening 16, the appearance casing 100 has the dismounting opening 101 disposed opposite to the drawing opening 16, and the purifying device 3 enters and exits the appearance casing 100 through the dismounting opening 101. That is, when the purifying device 3 is attached, the purifying device 3 can be pushed into the exterior case 100 and the fresh air case 1 through the attaching/detaching port 101 and the drawing/pulling port 16, and when the purifying device 3 is detached, the purifying device 3 can be pulled out of the fresh air case 1 and the exterior case 100 through the drawing/pulling port 16 and the attaching/detaching port 101, so that the purifying device 3 can be cleaned, replaced, and the like. Therefore, when the purifying device 3 is detached, the appearance housing 100 does not need to be detached or a part of the appearance housing 100 does not need to be detached, thereby greatly facilitating the operation of a user.

As shown in fig. 7-10, the dismounting opening 101 is located on at least one of the left and right side surfaces of the appearance housing 100, when the purification core 31 is located at the working position, the rear surface of the purification core 31 is a windward surface 311, the front surface of the purification core 31 is a leeward surface 312, the length center line of the purification core 31 extends along an arc and the center of the center line is located at the front side of the purification core 31, so that the purification core 31 is in an arc structure which is convexly curved backward, therefore, when the purification device 3 needs to be dismounted, the purification device 3 can slide along the arc-shaped rail 17 by pulling the purification device 3 forward, thereby facilitating the extraction of the purification device 3. It can be understood that, generally, the air treatment apparatus 1000 is disposed at a position of an indoor corner, the space of the front side of the air treatment apparatus 1000 is large, and by setting the curved form of the purification device 3 as above, the purification device 3 can be pulled to the front side to detach the purification device 3, so that the space can be effectively utilized, the operation space for detaching and attaching the purification device 3 is provided, and the problem that the purification device 3 cannot be detached due to collision with a wall or the like in the detaching process of the purification device 3 or interference of the wall is avoided.

As shown in FIGS. 7-10, in some embodiments of the present invention, the maximum width of the appearance housing 100 in the left-right direction is A, the diameter of the leeward surface 312 of the purification core 31 is D, D-100mm is not less than A not less than D +200mm, or 0.8A not less than D not less than 1.5D. From this, when outwards pull purifier 3, can avoid the problem that purifier 3 outward appearance casing 100 collided with that arouses because the D undersize on the one hand, on the other hand can avoid the problem that purifier 3 and surrounding environment barrier collided with that arouses because the D is too big to guarantee that purifier 3 can pull smoothly and take out.

For example, in the example shown in fig. 9, if the value of D is less than or equal to D1, the rotation diameter of the purifying device 3 is too small, and the purifying device 3 is likely to touch the appearance housing 100 itself during the process of removing the purifying device 3; if the value of D is greater than or equal to D2, the rotating diameter of the purifying device 3 may be too large, and during the process of removing the purifying device 3, the purifying device 3 may easily touch obstacles in the environment outside the air processing apparatus 1000, such as a sofa, a cabinet, etc. For example, in some specific examples of the present invention, D may also be set to: d-50mm is not less than A and not more than D +100mm, or 0.95A is not less than D and not more than 1.25D. Therefore, the purification device 3 can be better ensured to be smoothly drawn out.

In some embodiments of the present invention, as shown in fig. 7-10, the appearance housing 100 includes a rear housing 102 and a front housing 103, the front housing 103 is fitted to the front side of the rear housing 102, and the mounting/dismounting opening 101 is formed on the rear housing 102, wherein the minimum distance between the mounting/dismounting opening 101 and the front edge of the rear housing 102 is d, and d is greater than or equal to 10mm and less than or equal to 100 mm. Therefore, the local strength of the rear shell 102 is ensured to meet the requirement, the overall strength of the rear shell 102 is ensured to meet the requirement, and the overall size of the whole machine is ensured to be compact. For example, in some specific examples of the present invention, d may also be set to: d is more than or equal to 25mm and less than or equal to 50 mm. Therefore, the problem that the local strength of the appearance shell 100 near the dismounting port 101 is poor due to too small d value can be effectively avoided, and the problem that the thickness of the appearance shell 100 in the front-back direction is large due to too large d value can be avoided.

In some embodiments of the present invention, as shown in fig. 8, the purifying device 3 may further have a mounting frame 32 for fixing the purifying core 31, besides the purifying core 31, and the mounting frame 32 may be provided with a handle slot 321 for facilitating the user to pull and hold.
