Referring to fig. 1 to 13, the present invention provides an embodiment of a fresh air module and an air conditioner including the same; wherein the dashed arrows in fig. 5 and 9 indicate the airflow direction. The fresh air module can improve the efficiency of fresh air module air-purifying. The air conditioner can be any one of a wall-mounted air conditioner indoor unit, a cabinet air conditioner indoor unit, an air machine, a ceiling air conditioner indoor unit or a mobile air conditioner. In the following embodiments, an air conditioner is mainly described as an example of a wall-mounted air conditioner indoor unit, and other types may be referred to for implementation.

Referring to fig. 2, 3 and 9, in an embodiment of the fresh air module 200, the fresh air module 200 includes a housing 300, a fan assembly 400 and a purifying assembly 500. The shell 300 is provided with a fresh air inlet 301 and a fresh air outlet 302, a fresh air duct 330 is formed in the internal structure of the shell 300, and the fresh air inlet 301 and the fresh air outlet 302 are communicated through the fresh air duct 330; the fan assembly 400 is mounted in the fresh air duct 330; the purification assembly 500 is installed in the fresh air duct 330, and the purification assembly 500 is located at one axial end of the fan assembly 400 so as to correspond to the air inlet end of the fan assembly 400.

Specifically, the housing 300 of the fresh air module 200 may have a fresh air inlet 301 at the bottom thereof, and the housing 300 may have a fresh air outlet 302 at the top or the front side or the left side or the right side thereof, and in practical applications, the air conditioner 100 may be designed correspondingly according to the specific type of the fresh air module 200. Specifically, the bottom of the casing 300 may be provided with a fresh air inlet 301, the front side of the casing 300 may be provided with a fresh air outlet 302, and the fresh air inlet 301 and the fresh air outlet 302 are respectively located in different radial directions of the fan assembly 400.

Referring to fig. 5, when the fresh air module 200 works, the fan assembly 400 is turned on, the fan assembly 400 drives fresh air to enter the fresh air duct 330 from the fresh air inlet 301, the fresh air flows to the air inlet end of the fan assembly 400, and then is purified into relatively clean fresh air by the purifying assembly 500 at the air inlet end of the fan assembly 400, and then the clean fresh air enters the fan assembly 400 from the air inlet end thereof, is radially thrown out to the fresh air outlet 302 by the fan assembly 400, and finally is outwardly blown from the fresh air outlet 302.

Obviously, the fan assembly 400 is axially air-inlet and radially air-outlet, and for the narrow air inlet surface at the fresh air inlet 301 and near the fresh air inlet, a larger air inlet surface is formed at the air inlet end of the fan assembly 400, so that the air inlet space formed therein is also larger. Therefore, the purifying assembly 500 is arranged to correspond to the air inlet end of the fan assembly 400, and accordingly, the purifying surface for allowing the air of the purifying assembly 500 to pass through to realize purification is designed to be larger, so that the efficiency of increasing the air purifying of the purifying assembly 500 is improved. In addition, since the purge assembly 500 is designed to be relatively large, the amount of air that can be purged by the purge assembly 500 is correspondingly increased, and thus the life of the purge assembly 500 can be prolonged, and the period for replacing the purge assembly 500 can be prolonged.

As to the structure of the purification assembly 500, there may be various designs without limitation. Such as but not limited to: the purge assembly 500 includes a mounting frame 510 and a purge member 520 (shown in fig. 13) mounted on the mounting frame 510. The purifying member 520 may be adapted to remove any one or more of dust, fine particles, microorganisms, organic volatile gas (such as formaldehyde, etc.), and other air pollutants from the air. The specific type of the purifying member 520 can be selected according to the function thereof, and the purifying member 520 can be any one or combination of a common filter screen, a HEPA (high efficiency particulate air) screen, a formaldehyde remover and an IFD (internal-flow filtration) filter; and the filter screen can also be any one or combination of a plurality of primary filter screens, intermediate filter screens and high-efficiency filter screens.

According to the technical scheme of the invention, the purification component 500 is arranged at one axial end of the fan component 400 and corresponds to the air inlet end of the fan component 400, so that the large air inlet space at the air inlet end of the fan component 400 is utilized, the purification surface of the purification component 500 for air to pass through to realize purification is designed to be larger, and the efficiency of the purification component 500 for purifying air is improved. In addition, since the purification assembly 500 is correspondingly designed to be larger, the purification assembly 500 can capture and remove more air pollutants, and further, the service life of the purification assembly 500 can be prolonged, and the period for replacing the purification assembly 500 can be prolonged.

Referring to fig. 3, 5 and 9, in an embodiment, the fresh air module 200 further includes a middle partition plate 600 disposed in the fresh air duct 330, the middle partition plate 600 is located at an air inlet end of the fan assembly 400, and the middle partition plate 600 is provided with a vent hole 610 corresponding to the air inlet end of the fan assembly 400; the purification assembly 500 is installed at the middle partition 600 and is positioned at the air intake side of the ventilating holes 610.

Referring to fig. 2 and 10, in an embodiment, to facilitate the disassembly and assembly of the purification assembly 500, the casing 300 has a fresh air outlet 302 formed on a front side wall thereof, and a mounting opening 303 formed on one side of the fresh air outlet 302; the purification assembly 500 is installed on the middle partition 600 to be drawable from the installation opening 303.

Specifically, the mounting opening 303 is disposed in a strip shape and extends in the same direction as one side of the fresh air outlet 302. By mounting the purification assembly 500 on the middle partition 600 to be drawable from the mounting port 303, it is possible to allow the purification assembly 500 to have an operation state in which it is mounted on the middle partition 600 to correspond to the ventilation hole 610 of the middle partition 600, and a rest state in which it is drawn out from the middle partition 600 to the outside of the mounting port 303. Wherein, the purifying assembly 500 can purify the air flow flowing from the air inlet chamber 331 to the air outlet chamber 332 through the air vent 610 in the operating state, so as to remove the pollutants in the air; with the decontamination assembly 500 in an idle state, a user may clean or replace the decontamination assembly 500. The user can switch the state of purifying subassembly 500 by oneself through handheld pulling purifying subassembly 500, and is simple easy to operate.

In addition, the fresh air outlet 302 of the fresh air module 200 faces the area where the user is located, and the installation opening 303 of the pull-out purification assembly 500 is arranged on one side of the fresh air outlet 302, that is, the installation opening 303 faces the area where the user is located, so that the user can conveniently pull out the purification assembly 500 from the front side to switch the state of the purification assembly 500.

Referring to fig. 10 to 12, in an embodiment, to facilitate the pulling of the purification assembly 500 on the middle partition plate 600, the middle partition plate 600 is configured with a guide groove 620 at the periphery of the air inlet side of the ventilation hole 610, the guide groove 620 is disposed to be open towards the mounting opening 303 of the housing 300, and the guide groove 620 is adapted to guide the pulling installation of the purification assembly 500. The opening of the guide groove 620 is butted against the mounting hole 303 so that the purification module 500 moves along the guide groove 620 toward the vent hole 610 of the middle partition plate 600 after the purification module 500 is pushed through the mounting hole 303, and when reaching the inner end of the guide groove 620, the purification module 500 covers the vent hole 610.

It is considered that, when the purification assembly 500 is in the operation state, if a gap is formed between the guide groove 620 and the purification assembly 500, a part of the airflow entering from the fresh air inlet 301 may directly leak from the gap to the vent hole 610 and then enter the blower assembly 400 through the vent hole 610 without passing through the purification assembly 500. To reduce this, the shape of the guiding groove 620 is optionally adapted to the shape and size of the purifying assembly 500, and the inner wall surface of the guiding groove 620 is suitable for the outer peripheral wall of the purifying assembly 500 to contact and support so as to seal the gap between the two.

Specifically, when the purification assembly 500 is in an operating state, the inner wall surface of the guide groove 620 and the outer peripheral wall of the purification assembly 500 are in close contact and abutted together, so that the gap between the guide groove 620 and the purification assembly 500 is close to zero or extremely small, and the effect of sealing the gap between the two is achieved. As for the shape of the guide groove 620, it is required to conform to the shape of the purification assembly 500. The shape of the guide groove 620 can be designed accordingly according to the shape structure of the purification assembly 500. The shape of the purification assembly 500 may be, but is not limited to: the purification assembly 500 is provided in a semicircular shape, or a semi-elliptical shape, or a semi-racetrack shape.

Referring to fig. 10 to 12, in an embodiment, the purification assembly 500 is disposed in a hemiracetrack shape; accordingly, the guide groove 620 is also provided in a half-track shape. Specifically, the guide groove 620 has an arc-shaped guide wall 621 that surrounds the ventilation hole 610 on the side away from the installation opening 303, and a strip-shaped guide wall 622 that extends from both ends of the arc-shaped guide wall 621 in a straight line shape toward the installation opening 303, and the two strip-shaped guide walls 622 and the arc-shaped guide wall 621 are provided in a half-runner shape in cooperation.

Optionally, the height of the strip-shaped guide wall 622 protruding from the surface of the middle partition 600 is greater than the height of the arc-shaped guide wall 621 protruding from the surface of the middle partition 600, so that the inner wall surface of the strip-shaped guide wall 622 forms a guide surface with a larger area, which helps to guide the purification assembly 500 to enter or move out of the opening of the guide groove 620, and prevents the purification assembly 500 from deviating from the two sides of the opening of the guide groove 620 and separating from the guide groove 620.

To ensure the stability of the purification assembly 500 in the working state, elastic buckles 540 may be disposed at two opposite sides of the purification assembly 500; two strip-shaped guide walls 622 of the guide groove 620 are concavely provided with positioning grooves 623 corresponding to the elastic buckles 540, and the positioning grooves 623 are suitable for the elastic buckles 540 to correspondingly clamp, so that the purification assembly 500 is positioned in the guide groove 620.

When the purifying assembly 500 is installed, the purifying assembly 500 is pushed into the guide groove 620 along the installation opening 303, and when the purifying assembly 500 reaches the working state, the elastic buckle 540 on the purifying assembly 500 is just clamped with the positioning groove 623 on the strip-shaped guide wall 622 of the guide groove 620, so that the purifying assembly 500 is fixed, and the purifying assembly 500 is not easily loosened and separated. When the purification assembly 500 needs to be disassembled, the purification assembly 500 is forced to overcome the binding force of the elastic buckle 540 by using an external force, so that the elastic buckle 540 is elastically deformed and separated from the positioning groove 623, and the purification assembly 500 can be pulled out to be switched to an idle state.

Referring to fig. 10, 12 and 13, based on any of the above embodiments, since the purifying assembly 500 includes the mounting frame 510 and the purifying member 520 mounted on the mounting frame 510, in order to facilitate the pulling of the purifying assembly 500, optionally, the mounting frame 510 includes a main frame 511 and a side frame 512 configured at one end of the main frame 511, wherein the main frame 511 is configured with a mounting slot opened toward the front air chamber 3312 for mounting the purifying member 520, and the side frame 512 is suitable for being held by a user to pull the mounting frame 510, thereby implementing the integral pulling and mounting of the purifying assembly 500.

Further, the side frame 512 of the mounting frame 510 has an end plate 513 away from the main frame 511 of the mounting frame 510, the end plate 513 can be adapted to cover the mounting opening 303, and the end plate 513 is configured with a handle 530 for a user to hold. Because the end plate 513 can be adapted to cover the mounting opening 303, the overall appearance of the fresh air module 200 is smooth, and external impurities can be prevented from falling into the fresh air module 200 from the mounting opening 303 to cause pollution.

Referring to fig. 5, 7 and 8, regarding the shape structure of the pull handle 530, the pull handle 530 may be a pull ring, a handle slot or a handle hole. However, it is considered that the handle 530 with these shapes may be concave or convex relative to the other outer surfaces of the fresh air module 200, thereby destroying the integrity of the entire outer surface of the fresh air module 200.

In view of this, in order to improve the integrity of the entire outer surface of the fresh air module 200, the outer surface of the handle 530 may be flush with the outer surface of the end plate 513, and when a portion of the handle 530 is pressed inward, another portion of the handle 530 is rotated outward to be held by a user (as shown by the dotted arrow in fig. 8). Specifically, the pull 530 includes a pressing portion 531 and a pull portion 532 connected to the pressing portion 531, and a portion of the pull 530 located between the pressing portion 531 and the pull portion 532 is rotatably connected to the end plate 513. The position of the rotational mounting of the pull 530 is indicated at P in fig. 7 and 8.

Therefore, when the pressing portion 531 of the pull handle 530 is pressed inward, the pull handle 530 rotates relative to the end plate 513, so that the holding portion 532 of the pull handle 530 is rotated outward, and the user can pull out the mounting bracket 510 by holding. To facilitate pulling by the user, the inner wall surface of the handle 532 may be configured with a pull ring for the user to hold and pull, and the pull ring is hidden inside the end plate 513 when not in use, and is not exposed outwards, so as not to destroy the integrity of the whole outer surface of the fresh air module 200.

Referring to fig. 4, 5 and 9, based on any of the above embodiments, the middle partition plate 600 divides the fresh air duct 330 into an air inlet cavity 331 communicating with the fresh air inlet 301 and an air outlet cavity 332 communicating with the fresh air outlet 302, and the air outlet cavity 332 communicates with the air inlet cavity 331 through the vent hole 610 of the middle partition plate 600; the fan assembly 400 is located within the air outlet chamber 332.

Referring to fig. 9 and 10, the fan assembly 400 includes a centrifugal fan 410 and a first motor 420, wherein an air inlet end of the centrifugal fan 410 corresponds to the air vent 610 of the middle partition 600, and the other end of the centrifugal fan 410 is connected to the first motor 420, so that the centrifugal fan 410 is driven to rotate by the first motor 420. Fresh air entering the fresh air duct 330 from the fresh air inlet 301 passes through the purification assembly 500 to be purified into clean fresh air, then passes through the ventilation holes 610 of the middle partition plate 600 to enter the centrifugal wind wheel 410, and finally is blown out to the fresh air outlet by the centrifugal wind wheel 410.

In the above embodiment, the ventilation area of the ventilation hole 610 of the middle partition 600 may be substantially the same as the air inlet end area of the centrifugal wind wheel 410, or slightly smaller than the air inlet end area of the centrifugal wind wheel 410. The purification assembly 500 is arranged in a flat shape; the purification assembly 500 is disposed at the air inlet side of the ventilation hole 610, and the ventilation area of the purification member 520 is larger than that of the ventilation hole 610 to completely cover the ventilation hole 610, so that the purification assembly 500 obtains a larger purification surface, can capture more air pollutants, and improves the purification efficiency of the purification assembly 500.

Further, to facilitate the airflow passing through the purification assembly 500 to enter the centrifugal wind wheel 410 through the ventilation hole 610, optionally, the periphery of the ventilation hole 610 is configured with a wind guiding ring 611, and the wind guiding ring 611 is designed to be tapered from the periphery of the ventilation hole 610 towards the wind outlet cavity 332, so as to reduce the resistance of the airflow passing through the ventilation hole, and help to guide the airflow passing through the purification assembly 500 to enter the centrifugal wind wheel 410 through the ventilation hole 610.

Because the fresh air inlet 301 and the fresh air outlet 302 are respectively located in different radial directions of the fan assembly 400, an included angle is formed between the air inlet direction and the air outlet direction. Therefore, in order to facilitate the air entering from the fresh air inlet 301 to flow to the air inlet end of the fan assembly 400, the air inlet cavity 331 of the fresh air duct 330 extends from the fresh air inlet 301 to the middle partition 600 toward the air inlet end of the centrifugal wind wheel 410.
