Referring to fig. 1 and 4, the present invention provides an air purification module 100, wherein the air purification module 100 can be applied to an indoor unit 200 of an air conditioner, especially a floor type indoor unit of an air conditioner. The air purification module 100 is used for purifying air and sending the purified air to an indoor environment, thereby improving the air quality of the indoor environment.

Referring to fig. 5 to 7, in an embodiment of the air purification module 100 of the present invention, the air purification module 100 includes a housing 110, a rotating body 120, a supporting frame 130 and a coupling assembly. The housing 110 has a purge air duct 111. The rotating body 120 is rotatably installed at the purification air duct 111, the rotating body 120 is adapted to communicate with a water source to throw water out while rotating, and one end of the rotating body 120 is provided with a rotating shaft 121. The supporting frame 130 is disposed at one end of the rotating body 120, and the supporting frame 130 is provided with a bearing seat 131.

Referring to fig. 7 and 8, the coupling assembly includes a coupling flange 140 and a bearing 150; the bearing 150 has an inner ring 151 and an outer ring 152 (the bearing 150 can refer to fig. 14), and the inner circumferential wall of the inner ring 151 is fixedly connected with the bearing seat 131; one end of the coupling flange 140 is fixedly connected to the outer circumferential wall of the outer ring 152, and the other end of the coupling flange 140 is fixedly connected to the rotating shaft 121.

Specifically, the housing 110 may have a square shape, a circular shape, or the like. The cleaning air duct 111 formed in the housing 110 may extend in the vertical direction, in the horizontal direction, or in an inclined direction. Specifically, the purge air duct 111 extends in the vertical direction. The air outlet end and the air inlet end of the purifying air duct 111 may be formed at two ends of the casing 110, or formed at a side wall of the casing 110. The casing 110 is in a cylindrical shape with two open ends, so that an air inlet end of the purifying air duct 111 is formed at the lower end of the casing 110, and an air outlet end of the purifying air duct 111 is formed at the upper end of the casing 110.

The support bracket 130 may be installed in the housing 110, or installed at the water supply tank 160 or the base below the housing 110. The support bracket 130 and the coupling assembly cooperate to support the rotary body 120. Wherein, the inner ring 151 and the outer ring 152 of the bearing 150 are concentrically arranged, and the inner ring 151 and the outer ring 152 can relatively rotate. The inner circumferential wall of the inner ring 151 is fixedly connected with the bearing seat 131, one end of the connecting shaft flange 140 is fixedly connected with the outer circumferential wall of the outer ring 152, and the other end of the connecting shaft flange 140 is fixedly connected with the rotating shaft 121. When the rotating body 120 rotates at a high speed, the outer ring 152 of the bearing 150 rotates together with the rotating body 120, and the inner ring 151 of the bearing 150 is kept stationary relative to the bearing seat 131, so that the occurrence of rotation slip is avoided, and the smoothness and the balance of the rotating body 120 are ensured.

In addition, the coupling flange 140 is smaller in size than the coupling of the rotating body 120 directly to the bearing 150, and thus, is more easily fastened to the bearing 150. The shaft 121 is usually designed to have a certain length, and when the rotating body 120 rotates at a high speed, the shaft 121 bears a large rotating torque, which causes a large load to be borne by the shaft 121. After the connecting shaft flange 140 is added, the rotating torque of the rotating shaft 121 is shared by the connecting shaft flange 140, so that the rotating shaft 121 is not easily broken.

When the air purification module 100 purifies air, the air enters the purification air duct 111 and then flows in the purification air duct 111 from bottom to top. At the same time, the rotating body 120 rotates at a high speed to throw out the water at a high speed, and the thrown water is finely divided into a large number of water droplets having extremely small particle diameters. The water drops collide with the flowing air in the purifying air duct 111, so that impurities in the air are adsorbed and taken away, and the water is thrown and purified by supergravity. For example, fine particles, pollen, biological bacteria, volatile organic compounds (such as formaldehyde and benzene) in the purified air. In addition, the water drops are mixed into the air, and the effect of humidifying the air can be achieved.

The technical scheme of the utility model, adopt even axle subassembly to be connected rotator 120 and support frame 130's bearing frame 131, wherein, the internal perisporium of bearing 150's inner circle 151 is connected fixedly with bearing frame 131, even axle flange 140's one end is connected fixedly with the periphery wall of bearing 150's outer lane 152, even axle flange 140's the other end and pivot 121 fixed connection to make rotator 120 at high-speed rotatory in-process, avoid rotating the condition of skidding and take place, ensure rotator 120's stationarity and equilibrium. Furthermore, the rotating body 120 rotates smoothly, so that the shaking is not easy to occur, and the generation of abnormal noise such as shaking can be reduced.

Referring to fig. 7 and 9, according to the above embodiment, the rotating body 120 may be spherical, cylindrical, or square in shape. The rotation axis of the rotating body 120 may extend in the longitudinal direction (up and down direction), may extend in the left and right direction, or may extend obliquely. Specifically, the rotating body 120 is provided in a cylindrical shape, and the rotation axis of the rotating body 120 extends in the vertical direction.

Here, in order to drive the rotating body 120 to rotate, the air purification module 100 further includes a driving device 170 mounted to the housing 110, and the driving device 170 is drivingly connected to the other end of the rotating body 120 to drive the rotating body 120 to rotate. That is, one end of the rotating body 120 is rotatably connected to the bearing housing 131 through the coupling assembly, and the other end of the rotating body 120 is connected to the driving device 170, so that the driving device 170 can drive the rotating body 120 to rotate at a high speed with respect to the bearing housing 131 to throw water out of the rotating body 120.

The specific structure of the rotating body 120 is not limited herein. The rotating body 120 may be composed of a plurality of stacked disks, and a water throwing gap is formed between adjacent two disks. Or, the rotating body 120 includes a rotating frame, a first filter sleeved on the periphery of the rotating frame, and a second filter laid on the rotating frame along the radial cross section of the rotating body 120, and the meshes on the first filter and the second filter form a water throwing hole and a ventilation hole.

It is considered that when the linear velocity of the outer edge of the rotating body 120 is too small, the velocity of the water thrown out by the rotating body 120 is small, and the air purification effect is poor, and when the linear velocity of the outer edge of the rotating body 120 is too large, the energy consumption of the rotation of the rotating body 120 is large and the noise generated is large, and the improvement of the air purification effect by continuously increasing the linear velocity of the outer edge of the rotating body 120 is small.

Therefore, in the present embodiment, when the air purification module 100 is required to operate, the linear velocity of the outer edge of the rotating body 120 is 10m/s to 45 m/s. Such as but not limited to: 12m/s, 16m/s, 18m/s, 22m/s, 26m/s, 28m/s, 32m/s, 36 m/s. The linear velocity of the outer edge of the rotating body 120 is limited to 10m/s to 45m/s, so that the velocity of the water thrown out by the rotating body 120 is ensured to be high, and the noise generated by the rotation of the rotating body 120 is small.

Particularly, when the air purification module 100 works, the linear velocity of the outer edge of the rotating body 120 is 20m/s to 30m/s, and at this time, the rotating body 120 has the advantages of good purification effect, reasonable energy consumption and low noise. Such as but not limited to: 22m/s, 24m/s, 26m/s, 28 m/s.

Referring to fig. 10 to 12, in one embodiment, in order to improve the stability of the installation of the rotating body 120, the installation manner of the bearing 150 is modified. Specifically, the bearing seat 131 of the supporting frame 130 has a bearing installation groove 132, and a fixed shaft 133 is convexly disposed on the bottom surface of the bearing installation groove 132; the inner ring 151 is sleeved on the fixed shaft 133 and is in interference fit with the fixed shaft 133. With such a design, a gap is not easily formed between the inner ring 151 of the bearing 150 and the fixed shaft 133, and the stability of the connection between the inner ring 151 and the bearing housing 131 is ensured, thereby improving the stability of the installation of the rotating body 120.

Referring to fig. 10, 13 and 14, in an embodiment, the installation manner of the coupling flange 140 may be further modified. Specifically, the coupling flange 140 includes a coupling head 141 and a coupling tail 142 connected to the coupling head 141; the coupling head 141 is provided with a receiving cavity 1411 (as shown in fig. 15), and an inner circumferential wall of the receiving cavity 1411 is in interference fit with an outer circumferential wall of the outer ring 152; the coupling tail 142 is connected to the rotation shaft 121.

Specifically, the inner peripheral wall of the receiving cavity 1411 and the outer peripheral wall of the outer ring 152 are in interference fit, so that the two are tightly connected and a gap is not easily generated. In addition, an annular groove 143 is concavely provided at a position of the connecting head 141 near the coupling tail 142, and the annular groove 143 can reduce the weight of the coupling flange 140 and can prevent slipping.

Referring to fig. 13 to 15, in order to improve the stability of the connection between the connecting shaft flange 140 and the rotating shaft 121, a supporting side plate 122 is protruded from the end of the rotating shaft 121, and the supporting side plate 122 is connected and fixed to the end surface of the connecting shaft tail 142. During assembly, the rotating shaft 121 is supported on the end face of the connecting shaft tail 142 through the supporting side plate 122, and the supporting side plate 122 effectively increases the contact area of the connecting shaft tail 142 and the connecting shaft flange 140, so that the connecting stability of the connecting shaft flange 140 and the rotating shaft 121 is improved.

As for the connection mode of the connecting shaft flange 140 and the rotating shaft 121, it can be fixed by a snap structure or a screw structure in theory. For convenience of installation, a plurality of positioning pins 1421 are protruded from the end surface of the coupling tail 142; the supporting side plate 122 is disposed with a plurality of positioning holes 123, and the positioning holes 123 are respectively inserted into the positioning pins 1421 in a one-to-one correspondence. During assembly, the connecting flange 140 and the rotating shaft 121 can be fixedly connected by inserting the positioning holes 123 into the positioning pins 1421 one by one.

It is considered that if the positioning pin 1421 is interference-fitted into the positioning hole 123, the coaxiality between the bearing 150 and the rotating body 120 is difficult to be ensured, so that the rotating body 120 may be unstably rotated during the rotation of the rotating body 120. Therefore, in order for this to occur, a gap may be optionally formed between the inner wall surface of the positioning hole 123 and the outer wall surface of the positioning pin 1421.

In the rotation process of the rotating body 120, the gap between the positioning pin 1421 of the connecting flange and the positioning hole 123 of the rotating body 120 can effectively offset the slight difference between the rotation axes of the bearing 150 and the rotating body 120, thereby ensuring the coaxiality of the bearing 150 and the rotating body 120, reducing the occurrence of unstable rotation of the rotating body 120 in the rotation process, and improving the stability of rotation.

Further, it is considered that, when the shaft connecting flange 140 is assembled with the rotating shaft 121, in the process of aligning the positioning pin 1421 with the positioning hole 123, a gap between the shaft connecting flange 140 and the rotating shaft 121 is narrow, which is not enough to observe whether the positioning pin 1421 is accurately aligned with the positioning hole 123.

Referring to fig. 13 to 15, to solve the problem, the side wall of the connecting shaft tail 142 is provided with a first positioning portion 1422, the side surface of the supporting side plate 122 is provided with a second positioning portion 124 corresponding to the first positioning portion 1422, and when the first positioning portion 1422 corresponds to the second positioning portion 124, the positioning pin 1421 corresponds to the corresponding positioning hole 123.

During assembly, only by observing from the outside of the coupling flange 140, whether the first positioning portion 1422 corresponds to the second positioning portion 124, and when the first positioning portion 1422 corresponds to the second positioning portion 124, the positioning pin 1421 also corresponds to the corresponding positioning hole 123, so that the positioning pin 1421 can be accurately inserted into the corresponding positioning hole 123, and the assembly efficiency is greatly improved.

As to the specific structure of the first positioning portion 1422 and the second positioning portion 124, the first positioning portion 1422 and/or the first positioning portion 1422 may be ribs or grooves. The first positioning portion 1422 and/or the first positioning portion 1422 may also serve as an anti-slip structure to prevent the user from slipping when holding the coupling flange 140.

Referring to fig. 9 to 11, in one embodiment, in order to supply water to the rotating body 120, the air purification module 100 further includes a water supply tank 160 and a water supply pipe 170, the water supply tank 160 being located below the housing 110, the water supply tank 160 serving as a water source of the rotating body 120; the water supply pipe 170 communicates the water supply pipe 170 with the rotating body 120 to supply the water of the water supply tank 160 to the rotating body 120.

There are two mounting manners for the water supply pipe 170. One embodiment is as follows: the water supply pipe 170 is provided at the outside of the case 110, the lower end of the water supply pipe 170 is communicated with the water supply tank 160 through a water pump, and the upper end of the water supply pipe 170 is connected with a spray head provided above or below the rotating body 120 to spray mist or water drops to the rotating body 120 through the spray head. The other installation mode is as follows: the water supply pipe 170 is inserted on the rotation axis of the rotating body 120 to spray water from the inside of the rotating body 120 thereto.

Referring to fig. 9 to 11, in detail, the water supply pipe 170 is inserted on the rotation axis of the rotating body 120. In view of the bearing seat 131 on the supporting frame 130, a fixing shaft 133 is protruded from the bottom surface thereof. In order to prevent the water supply pipe 170 from interfering with other components during the rotation of the rotating body 120, optionally, the water supply pipe 170 sequentially penetrates the fixed shaft 133 and the rotating shaft 121 from the inside of the water supply tank 160 to extend into the rotating body 120, and a plurality of water spray holes are formed through a portion of the water supply pipe 170 located inside the rotating body 120.

Since the water supply pipe 170 is located on the rotation axis of the rotating body 120, the water supply pipe 170 rotates corresponding to itself when the rotating body 120 rotates, and thus is not easily interfered with other members. During the rotation of the water supply pipe 170, water is sprayed to the rotating body 120 through the water spray holes to supply a sufficient amount of water to the rotating body 120.

Referring to fig. 9 and 10, based on any of the above embodiments, the air purification module 100 further includes a fan device 180, the fan device 180 is installed at an end of the casing 110 away from the supporting frame 130, and the fan device 180 is communicated with the air duct outlet of the purification air duct 111. The blower device 180 includes a blower housing, a blower mounted in the blower housing, and a motor connected to the blower. The fan drives the air in the purge air duct 111 to blow out to the air duct outlet, and then blows out through the purge air outlet 212 on the casing 210 of the indoor unit 200 of the air conditioner.

Referring to fig. 2 to 4, the present invention further provides an air conditioner indoor unit 200. The indoor unit 200 of the air conditioner includes a cabinet 210 and an air purification module 100. Wherein, the cabinet 210 is provided with a purge air inlet 211 and a purge air outlet 212. The specific structure of the air purification module 100 refers to the above embodiments, and since the air conditioner indoor unit adopts all technical solutions of all the above embodiments, all the beneficial effects brought by the technical solutions of the above embodiments are also achieved, and are not described in detail herein.
