Taking "A and / or B" as an example, it includes solution A, or solution B, or a solution that satisfies both A and B.

[0047] See also Figures 1 to 9 The present invention provides an embodiment of a fresh air module and an air conditioner including the fresh air module. Figure 5 The dotted arrow in the figure indicates the direction of air flow. The air conditioner can be any one of a wall-mounted air conditioner indoor unit, a cabinet-type air conditioner indoor unit, an air conditioner, a ceiling-mounted air conditioner indoor unit, or a mobile air conditioner. In the embodiments below, the air conditioner is mainly introduced as a wall-mounted air conditioner indoor unit, and other types can be implemented with reference to this.

[0048] See also Figures 1 to 5The fresh air module includes a housing 10, a fan assembly and a motor cover 30. The housing 10 is provided with a fresh air inlet 102 and a fresh air outlet 103. A fresh air duct 101 is formed in the housing 10. The fresh air duct 101 connects the fresh air inlet 102 and the fresh air outlet 103. The fan assembly includes a motor and a wind wheel 60. The wind wheel 60 is arranged in the fresh air duct 101. The motor includes a motor body 32 and a motor shaft 31. The motor shaft 31 is drivingly connected to the wind wheel 60 to drive the wind wheel 60 to rotate, guide the airflow from the fresh air inlet 102 into the fresh air duct 101, and flow out through the fresh air outlet 103. The motor cover 30 is arranged in the housing 10 and is located outside the fresh air duct 101. A motor cavity is formed in the motor cover 30, and the motor body 32 is arranged in the motor cavity. A partition 40 is provided between the motor cavity and the fresh air duct 101 so that the motor cavity and the fresh air duct 101 are separated from each other. The motor shaft 31 passes through the partition 40 and is drivingly connected to the wind wheel 60 .

[0049] Specifically, the housing 10 of the fresh air module may have a fresh air inlet 102 at its bottom, and a fresh air outlet 103 at its top, front side, left side, or right side. In practical applications, the fresh air module may be designed accordingly in combination with the specific type of air conditioner to which the fresh air module is applied. Specifically in this embodiment, the housing 10 may have a fresh air inlet 102 at its bottom, and the housing 10 may have a fresh air outlet 103 at its side. The fresh air inlet 102 and the fresh air outlet 103 are located in different radial directions of the fan assembly. Figure 5 When the fresh air module is working, the fan assembly is turned on, and the fan assembly drives the fresh air to enter the fresh air duct 101 from the fresh air inlet 102. This part of the fresh air first flows to the air inlet end of the wind wheel 60, and then flows from the air outlet end of the wind wheel 60 to the fresh air outlet 103, and is blown out from the fresh air outlet 103.

[0050] The motor includes a motor body 32 and a motor shaft 31. The motor body 32 is provided with a component for driving the motor shaft 31 to rotate. Air noise, mechanical noise, electromagnetic noise, etc. are generated during operation. In the existing air conditioner, the motor is placed in the air duct, and the diffusion effect of the air duct on the noise causes the noise to increase. In this embodiment, the motor cover 30 is located outside the fresh air duct 101, and a partition 40 is provided between the motor cavity and the fresh air duct 101 so that the motor cavity and the fresh air duct 101 are separated from each other. The motor shaft 31 is passed through the partition 40 and is connected to the wind wheel 60. The motor body 32 is arranged outside the fresh air duct 101 and is isolated from the fresh air duct 101 by the partition 40 to avoid the amplification effect of the wind cavity on the noise, thereby reducing the noise generated by the fresh air module.

[0051] It should be noted that the motor cover 30 is arranged in the shell 10, and can be protruding from the outer wall of the shell 10, or arranged inside the shell 10, as long as the motor cover 30 is located outside the fresh air duct 101. The motor cover 30 can be set separately from the shell 10, or it can be formed integrally with the shell 10, or it can be a part of the shell 10. It can be understood that when the motor cover 30 is located in the shell 10, when the motor is working, it is easier to drive the shell 10 to vibrate and generate noise, and the solid sound is faster, causing the noise to increase. For this reason, please refer to Figure 5 and Fig. 9 The motor cover 30 is protruded from the outer wall of the shell 10 so that the motor cavity is located outside the fresh air duct 101.

[0052] The air in the outdoor environment usually carries impurities such as dust and bacteria, which is not good for the health of users in the long run. Figure 4 and Figure 5 , the fresh air module provided by the present invention also includes a purification component 20, which is arranged in the fresh air duct 101 and between the fresh air inlet 102 and the fresh air outlet 103, so that the airflow flows through the purification component 20. The structure of the purification component 20 can have a variety of design schemes, which are not limited here. For example, but not limited to: the purification component 20 includes a mounting frame and a purification component installed on the mounting frame. The purification component can be used to remove any one or more of air pollutants such as dust, fine particles, microorganisms, and organic volatile gases such as formaldehyde in the air. The specific type of the purification component can be selected according to its function. The purification component can be any one or a combination of two of an ordinary filter or a HEPA filter or a formaldehyde remover or an IFD filter; it can also be any one or a combination of a primary filter, a medium filter, and a high-efficiency filter. In this way, the fresh air flowing into the room from the outdoor can be purified, which is beneficial to improving the indoor air quality.

[0053] For further information, see Figure 4 and Figure 5 , the purification component 20 is located at one end of the wind wheel 60 in the axial direction to correspond to the air inlet end of the wind wheel 60. In the present embodiment, the wind wheel 60 is axially air inlet and radially air outlet. Obviously, compared with the relatively narrow air inlet surface at and near the fresh air inlet 102, a larger air inlet surface is formed at the air inlet end of the fan assembly, so that the air inlet space formed therein is also larger. Therefore, the purification component 20 is set to correspond to the air inlet end of the fan assembly, and the purification surface of the purification component 20 through which the air passes to achieve purification can be designed to be larger accordingly, thereby increasing the efficiency of the purification component 20 in purifying the air. In addition, since the purification component 20 is designed to be larger accordingly, the amount of air that can be purified by the purification component 20 is correspondingly increased, and the life of the purification component 20 can also be extended, and the cycle of replacing the purification component 20 can be extended.

[0054] Based on the previous embodiment, please refer to Figure 4 , Figure 5 and Figure 7 The fresh air module also includes a middle partition 13 disposed in the fresh air duct 101. The middle partition 13 is located at the air inlet end of the wind wheel 60. The middle partition 13 is provided with a vent 130 corresponding to the air inlet end of the wind wheel 60. The purification component 20 can be pulled out and installed on the middle partition 13 and is located on the air inlet side of the vent 130. In this way, the purification component 20 can be cleaned or replaced by the user when it is idle. The user can disassemble and replace the purification component 20 by hand by pulling the purification component 20, which is simple and easy to operate.

[0055] In one embodiment, see Figure 2 , Figure 4 and Figure 5 The shell body 10 includes a bottom shell 11 and a shell cover 12. The bottom shell 11 has a front side facing the first direction and a rear side facing away from the first direction. The front side of the bottom shell 11 is open. The shell cover 12 is covered on the front side of the bottom shell 11. The middle partition 13 is arranged between the bottom shell 11 and the shell cover 12. The fresh air duct 101 includes an air inlet cavity 1011 and an air outlet cavity 1012. An air inlet cavity 1011 is formed between the shell cover 12 and the middle partition 13. An air outlet cavity 1012 is formed between the middle partition 13 and the bottom shell 11. The wind wheel 60 is arranged in the air outlet cavity 1012. In this way, the fresh air duct 101 is divided into an air inlet chamber 1011 and an air outlet chamber 1012 by the middle partition 13, and the wind wheel 60 is arranged in the air outlet chamber 1012. The purification component 20 prevents dust and other impurities from entering the air outlet chamber 1012, so that the wind wheel 60 in the air outlet chamber 1012 will not be affected by the impurities, the service life of the wind wheel 60 is extended, and it is easy to clean the wind wheel 60. The arrangement of the bottom shell 11 and the shell cover 12 is conducive to the assembly of the fresh air module.

[0056] Based on the previous embodiment, please refer to Figure 5 and Fig. 9 The motor cover 30 is convexly disposed on the rear side of the bottom shell 11, so that the motor shaft 31 extends from the motor body 32 along the first direction to the air outlet cavity 1012, and is drivingly connected to the wind wheel 60. In this way, the motor and the wind wheel 60 are both located on the side of the housing 10 where the air outlet cavity 1012 is located, which is convenient for installation and prevents the wind wheel 60 shaft from passing through the air inlet cavity 1011.

[0057] Preferably, the motor cover 30 is integrally formed with the bottom shell 11, an installation opening is provided on the bottom shell 11, the motor cavity is connected with the air outlet cavity 1012 through the installation opening, and the partition 40 is covered on the installation opening. In this way, when assembling the fresh air module, the operator only needs to operate from the first direction to install the motor and the wind wheel 60, and there is no need to repeatedly switch directions between the front and rear sides of the bottom shell 11 during the installation process, thereby improving the assembly efficiency. In addition, since the motor cover 30 and the bottom shell 11 are integrally formed, there is no relative displacement between the two, which avoids the motor cover 30 and the bottom shell 11 colliding with each other under the vibration of the motor to generate noise, thereby further reducing the noise of the fresh air module during operation.

[0058] There are many ways to fix the partition 40 to the bottom shell 11. In this embodiment, please refer to Figure 8 and Fig. 9 , the bottom shell 11 is provided with a plurality of studs 41 with openings facing the first direction, and the plurality of studs 41 are spaced apart along the circumference of the installation opening, and the partition 40 is provided with a plurality of screws, and each screw is screwed to each stud 41, so that the partition 40 is fixed to the bottom shell 11. In this way, the partition 40 is fixed by the cooperation of the screws and the studs 41, and the motor body 32 is also fixed in the motor cavity. Compared with the screw hole, the matching area between the screw and the stud 41 is large, and the friction force is large. On the one hand, the installation is firm, and on the other hand, relative shaking is not easy to occur, thereby reducing the noise generated under the vibration of the motor. The openings of the studs 41 are all facing the first direction, which is conducive to the operator to operate in the first direction and improve the installation efficiency.

[0059] Based on the previous embodiment, please refer to Figure 3 and Fig. 9 A plurality of accommodating shells 304 are provided on the circumferential side of the motor cover 30. The plurality of accommodating shells 304 are spaced apart along the circumferential direction of the motor cover 30 and are formed integrally with the motor cover 30. A accommodating groove extending along the first direction is formed in each accommodating shell 304, and each stud 41 is provided in each accommodating groove. In this way, the stud 41 is constructed in the accommodating groove, and the accommodating shell 304 is formed integrally with the motor cover 30. The stud 41 is more firmly arranged, and is not easy to generate noise due to shaking. The appearance is simple and easy to form.

[0060] Based on the above two embodiments, please refer to Figure 8 In this embodiment, a plurality of positioning ribs are convexly provided on the bottom shell 11, and the plurality of positioning ribs are spaced apart along the circumference of the installation opening, and a plurality of notches 42 are provided on the circumferential side of the partition 40, and each positioning rib is correspondingly inserted into each notch 42. In this way, when fixing the partition 40, the operator can first insert the partition 40 on the plurality of positioning ribs for pre-positioning, and then use a tool to drive the screws into the studs 41 for connection and fixing. There is no need for additional positioning when driving the screws, which is convenient to operate and has high installation efficiency.

[0061] In one embodiment, see Figure 1 and Figure 2 , a wiring port 301 is provided on the lower side of the motor cover 30. The wiring port 301 is used for the wires connected to the motor body 32 to pass through. The motor needs to be connected to external electronic devices through a power line or a signal line, so it is necessary to open a wiring port 301 on the motor cover 30. Since the fresh air module introduces outdoor air, when the air conditioner is in a cooling state, the outdoor air temperature is high and the indoor air temperature is low, and condensation water is easily generated on the outer surface of the shell 10 and the motor cover 30. When the fresh air module is adjacent to the heat exchange air duct or is located in the heat exchange air duct, more condensation water will be generated. Condensation water may also be generated on other surfaces inside the air conditioner. If condensation water flows into the motor cavity, it may cause damage to the motor. For this reason, in this embodiment, the wiring port 301 is located on the lower side of the motor cover 30 to prevent external condensation water from dripping directly into the wiring port 301, causing the motor to be damaged by moisture.

[0062] For further information, see Figure 2 The outer wall of the motor cover 30 is provided with a water baffle 302, which is distributed around the wiring port 301 to block the water flowing to the wiring port 301. In this way, the condensed water flowing along the surface of the motor cover 30 is prevented from flowing into the wiring port 301, causing the motor to be damaged by moisture.

[0063] Based on the above two embodiments, please continue to refer to Figure 2 In this embodiment, a wire groove rib 303 is convexly provided on the rear side of the bottom shell 11. The wire groove rib 303 and the bottom shell 11 together enclose a wire groove. The wire groove extends along the wiring direction to accommodate the wires extending from the wiring holes. The wire groove extends in a bent shape to have a water collection bend 3031. The water collection bend 3031 is configured to avoid the electronic devices in the air conditioner.

[0064] In one embodiment, see Fig. 9 A first rubber gasket 51 is provided between the motor body 32 and the separator 40, and a second rubber gasket 52 is provided between the motor body 32 and the motor cover 30. The first rubber gasket 51 and the second rubber gasket 52 are respectively located at both ends of the motor body 32 in the extending direction of the motor shaft 31, so that the motor body 32 is limited in the extending direction of the motor shaft 31. In this embodiment, the motor is fixed in the motor cover 30 by the first rubber gasket 51 and the second rubber gasket 52. Since rubber has a certain elasticity, it can effectively absorb the vibration of the motor, thereby reducing the noise generated by the motor during operation.

[0065] Based on the previous embodiment, please continue to refer to Fig. 9, annular step grooves are formed on the separator 40 and the motor cover 30, respectively, and the first rubber gasket 51 and the second rubber gasket 52 are respectively accommodated in the annular step grooves, so that the motor body 32 is limited in the radial direction of the motor shaft 31. As shown in the figure, the motor body 32 is effectively limited in the axial direction and radial direction of the motor shaft 31, and the installation is more secure, and it avoids direct contact with the separator 40 and the motor cover 30 with greater rigidity, reduces the installation gap, and reduces the noise generated by the vibration of the motor during operation.

[0066] See also Figure 1 The present invention also provides an air conditioner, which includes a housing 200 and a fresh air module installed in the housing 200. The specific structure of the fresh air module refers to the above embodiment. Since the present air conditioner adopts all the technical solutions of all the above embodiments, it at least has all the beneficial effects brought by the technical solutions of the above embodiments, which will not be repeated here. The air conditioner is any one of a wall-mounted air conditioner indoor unit, a cabinet air conditioner indoor unit, an air machine, a ceiling-mounted air conditioner indoor unit, or a mobile air conditioner. The following text takes the air conditioner as a wall-mounted air conditioner indoor unit as an example for introduction and explanation.

[0067] In one embodiment, the housing 200 is provided with an air inlet 201, a first air outlet 202 and a second air outlet 203, wherein the air inlet 201 is connected to the first air outlet 202.

Thus, the air conditioner has an indoor air circulation mode and a fresh air mode, wherein:

[0068] In the indoor air circulation mode, the air of the indoor environment enters the housing 200 through the air inlet 201, forms cold air or hot air after heat exchange by the heat exchange component inside the housing 200, and then blows back to the indoor environment from the first air outlet 202, thus realizing indoor air circulation;

[0069] In the fresh air mode, air from the outdoor environment enters the fresh air module through the fresh air duct, is purified by the purification component of the fresh air module to form clean fresh air, and then is blown from the fresh air outlet 103 of the fresh air module to the second air outlet 203 of the casing 200, and finally is blown from the second air outlet 203 to the indoor environment, thereby replenishing fresh air for the indoor environment.

[0070] Optionally, the casing 200 includes a chassis 211, a face frame 212 and a panel 213. The fresh air module is installed at the end of the chassis 211. The fresh air outlet 103 of the fresh air module is open to the face 213. Correspondingly, the panel 213 is provided with a second air outlet 203 at a position corresponding to the fresh air outlet 103, so that the air conditioner can deliver fresh air forward, so that the fresh air can accurately reach the user's location.

[0071] In addition, in order to prevent the fresh air from blowing directly onto the user, the second air outlet 203 can be optionally composed of a plurality of microholes that are arranged on the panel 213, so that after the fresh air is blown out from the plurality of microholes, the airflow is broken up into strands of smaller filaments, the wind speed is reduced, the airflow becomes softer, and will not blow directly onto the user, thereby preventing the user from feeling uncomfortable.

[0072] The above description is only a preferred embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the inventive concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
