Description

Technical Field

[0001] This invention relates to the field of air conditioning technology, and more specifically, to a fresh air module and an air conditioner. Background Technology

[0002] Currently, the fresh air modules in air conditioners on the market have limited functionality, only able to introduce outdoor air into the room in fresh air mode, resulting in a poor user experience. Summary of the Invention

[0003] The problem solved by this invention is that the fresh air module has limited functionality and a poor user experience.

[0004] To address the aforementioned issues, this invention provides a fresh air module that simultaneously possesses purification and wastewater discharge functions, significantly enhancing the user experience.

[0005] An embodiment of the present invention provides a technical solution:

[0006] A fresh air module includes a housing, a fan, and a purification filter. The housing is provided with an air inlet chamber and a fan chamber. The housing is provided with a purification air inlet, a waste air inlet, an outdoor exhaust air outlet, and an indoor air outlet. The fan is installed in the fan chamber. The outdoor exhaust air outlet and the indoor air outlet are selectively connected to the fan chamber.

[0007] The purification filter is installed in the air inlet chamber, dividing the air inlet chamber into a purification air inlet chamber and a waste air inlet chamber. The waste air inlet chamber is connected to the fan chamber, the purification air inlet is connected to the purification air inlet chamber, and the waste air inlet is connected to the waste air inlet chamber.

[0008] The fresh air module provided in this embodiment of the invention can operate in both purification and exhaust modes in practical applications. In purification mode, the fan operates, drawing indoor air into the purification inlet chamber through the purification inlet, purifying it through the purification filter before it enters the waste air inlet chamber, and finally drawing it into the fan chamber from the waste air inlet chamber, and exhausting it into the room through the indoor air outlet, thus purifying the indoor air. In exhaust mode, the fan operates, drawing indoor air into the waste air inlet chamber through the waste air inlet, and then drawing it into the fan chamber from the waste air inlet chamber, before exhausting it to the outside through the outdoor air outlet, thus removing waste from the indoor air. Therefore, the fresh air module provided in this embodiment of the invention simultaneously possesses indoor air purification and indoor air exhaust functions, resulting in a better user experience.

[0009] In an optional embodiment, the air inlet surface of the purification filter forms an acute angle with the horizontal plane, the air inlet surface of the purification filter serves as a partial sidewall defining the purification air inlet cavity, and the air outlet surface of the purification filter serves as a partial sidewall defining the waste air inlet cavity.

[0010] The air inlet and outlet surfaces of the purification filter define the purification air inlet chamber and the waste air inlet chamber, respectively. The waste air inlet chamber is connected to the fan chamber, so that the indoor polluted air can flow directly into the fan chamber without passing through the purification filter, thus avoiding contamination of the purification filter.

[0011] In an optional embodiment, the purification air inlet is located on the top wall of the housing, or the purification air inlet is located on the left side plate of the housing.

[0012] The top wall of the casing corresponds to the top wall of the indoor unit. The air purification inlet is located on the top wall of the casing. In practical applications, it can suck away the dust on the top wall of the indoor unit, thus cleaning the top wall of the indoor unit.

[0013] The left side panel is directly opposite the side panel of the casing. By opening the purification air inlet on the left side panel of the casing, lateral air intake can be achieved. The lateral air intake is far away from the heat exchange return air inlet at the top of the indoor unit, which can avoid the heat exchange return air interfering with the purification air intake and ensure the purification air volume.

[0014] In an optional embodiment, the waste air inlet is located on the top wall of the housing.

[0015] Similarly, the air inlet is located on the top wall of the casing. In practical applications, it can suck away dust from the top wall of the indoor unit, thus cleaning the top wall of the indoor unit.

[0016] In an optional embodiment, the end of the purification filter that is closer to the waste air inlet in the vertical direction is closer to the waste air inlet in the horizontal direction than the end that is farther away from the waste air inlet.

[0017] The upper end of the purification filter is close to the air inlet for polluted air, and the filter is tilted to the left from top to bottom. This prevents dust from accumulating on the air outlet of the filter in the exhaust mode, thus avoiding clogging and bacterial growth. It also prevents the risk of dust being blown away by the exhaust air when switching to purification mode. In an optional embodiment, a first mounting hole is provided on the side wall of the housing, through which the purification filter is inserted or removed from the housing.

[0018] In an optional embodiment, a first guide slide assembly is provided on the inner sidewall of the housing, and the purification filter screen is slidably engaged with the first guide slide assembly.

[0019] The purification filter slides into or out of the housing through the first mounting hole along the first guide slide assembly, making it easy and quick to install and remove, and easy to clean and replace.

[0020] In an optional embodiment, the fresh air module further includes a movable baffle that covers the purified air inlet and the polluted air inlet. The movable baffle is used to move relative to the housing under the action of an external force to selectively open one of the purified air inlet and the polluted air inlet.

[0021] By sliding the movable baffle horizontally, the opening and closing of both the purified air inlet and the sewage air inlet can be controlled, thereby enabling the start and stop control of the purification and sewage discharge functions.

[0022] In an optional embodiment, the fan cavity is provided with an air inlet and an air outlet, the air inlet being connected to the waste air inlet cavity, and the air outlet being connected to the outdoor exhaust vent and the indoor exhaust vent.

[0023] The fresh air module also includes an air outlet switching component, which is disposed on the housing and is used to selectively open one of the outdoor exhaust vent and the indoor air outlet.

[0024] In purification mode, the air outlet switching component opens the indoor air outlet and closes the outdoor air outlet, allowing purified air from the outlet to be introduced into the room through the indoor air outlet. In sewage discharge mode, the air outlet switching component opens the outdoor air outlet and closes the indoor air outlet, allowing polluted air from the outlet to be discharged outdoors through the outdoor air outlet.

[0025] An embodiment of the present invention also provides an air conditioner, including a housing and the aforementioned fresh air module. The fresh air module includes a housing, a fan, and a purification filter. The housing is provided with an air inlet cavity and a fan cavity. The housing is provided with a purification air inlet, a waste air inlet, an outdoor exhaust air outlet, and an indoor air outlet. The fan is installed in the fan cavity, and the outdoor exhaust air outlet and the indoor air outlet are selectively connected to the fan cavity. The purification filter is installed in the air inlet cavity and divides the air inlet cavity into a purification air inlet cavity and a waste air inlet cavity. The purification air inlet cavity is connected to the waste air inlet cavity through the purification filter. The waste air inlet cavity is connected to the fan cavity. The purification air inlet is connected to the purification air inlet cavity, and the waste air inlet is connected to the waste air inlet cavity. The housing has a first opening corresponding to the purification air inlet, a second opening corresponding to the waste air inlet, and a third opening corresponding to the indoor air outlet. The first opening and / or the second opening are located on the top wall of the housing, and the third opening is located adjacent to the heat exchange air outlet on the housing.

[0026] The air conditioner provided in this embodiment of the invention can operate in purification mode and exhaust mode respectively in practical applications. In purification mode, the fan operates, drawing indoor air into the purification inlet chamber through the purification inlet, filtering it through the purification filter, and then into the waste air inlet chamber. Finally, the waste air inlet chamber is drawn into the fan and exhausted into the room through the indoor air outlet, thus purifying the indoor air. In exhaust mode, the fan operates, drawing indoor air into the waste air inlet chamber through the waste air inlet, drawing it into the fan, and then exhausting it to the outside through the outdoor air outlet, thus removing waste from the indoor air. Therefore, the fresh air module provided in this embodiment of the invention has both indoor air purification and indoor air exhaust functions, resulting in a better user experience.

Detailed Implementation

[0036] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0037] Please see Figure 1 , Figure 1 The image shown is a cross-sectional view of the fresh air module 100 provided in this embodiment in fresh air mode.

[0038] The fresh air module 100 provided in this embodiment is applied to an air conditioner 200. The fresh air module 100 includes a housing 110, a fan 120, a purification filter 130, a fresh air filter 140, and an air outlet switching assembly 180. The housing 110 has an air inlet chamber and a fan chamber 111. The housing 110 has a purification air inlet 112, an outdoor exhaust air outlet 113, a waste air inlet 114, an indoor air outlet 115, and a fresh air outlet 119. The fan 120 is installed in the fan chamber 111.

[0039] The fan cavity 111 is provided with an air inlet 1111 and an air outlet 1112. The air inlet 1111 is connected to the air inlet cavity. The air outlet switching component 180 is disposed on the housing 110 and is used to selectively connect the fresh air inlet 119 to the air inlet cavity, and to connect the air outlet 1112 of the fan cavity 111 to the outdoor exhaust vent 113 or the indoor exhaust vent 115. It is also used to block the connection between the fresh air inlet 119 and the air inlet cavity when the air outlet 1112 is connected to the outdoor exhaust vent 113.

[0040] Both the purification filter 130 and the fresh air filter 140 are installed in the air inlet cavity, which divides the air inlet cavity into a purification air inlet cavity 116, a fresh air inlet cavity 117, and a waste air inlet cavity 118. The purification air inlet cavity 116 is connected to the waste air inlet cavity 118 through the purification filter 130. The fresh air inlet cavity 117 is connected to the waste air inlet cavity 118 through the fresh air filter 140. The waste air inlet cavity 118 is connected to the fan cavity 111. The purification air inlet 112 is connected to the purification air inlet cavity 116. The fresh air inlet 119 is connected to the fresh air inlet cavity 117. The waste air inlet 114 is connected to the waste air inlet cavity 118.

[0041] In practical applications, when the air conditioner 200 operates in fresh air mode, the purified air inlet 112 and the polluted air inlet 114 are closed. The air outlet switching component 180 connects the fresh air inlet 119 to the fresh air intake chamber 117 and connects the air outlet 1112 of the fan chamber 111 to the indoor air outlet 115. In this state, the fan 120 rotates, drawing outdoor fresh air into the fresh air intake chamber 117 through the fresh air inlet 119. The outdoor fresh air entering the fresh air intake chamber 117 is filtered and purified by the fresh air filter 140 before flowing into the polluted air intake chamber 118. Then, it flows into the fan chamber 111 from the air inlet 1111 and out of the fan chamber 111 from the air outlet 1112, and into the room through the indoor air outlet 115, thus completing the introduction of outdoor fresh air.

[0042] Please refer to the following: Figure 2 , Figure 2 The image shown is a cross-sectional view of the fresh air module 100 provided in this embodiment in purification mode.

[0043] When the air conditioner 200 operates in purification mode, the polluted air inlet 114 is closed, the purified air inlet 112 is opened, and the air outlet switching component 180 blocks the connection between the fresh air inlet 119 and the fresh air inlet cavity 117, while connecting the air outlet 1112 of the fan cavity 111 to the indoor air outlet 115. In this state, the fan 120 rotates, drawing indoor air into the purified air inlet cavity 116 through the purified air inlet 112. After entering the purified air inlet cavity 116, the indoor air is filtered and purified by the purification filter 130 before flowing into the polluted air inlet cavity 118. Then, it flows into the fan cavity 111 through the air inlet 1111, and then out of the fan cavity 111 through the air outlet 1112, before flowing into the room through the indoor air outlet 115, thus completing the purification of the indoor air.

[0044] To prevent dust in the polluted air entering the polluted air inlet cavity 118 through the polluted air inlet 114 from settling on the purification filter 130, in this embodiment, the purification filter 130 and the polluted air inlet 114 are vertically offset, and the end of the purification filter 130 closer to the polluted air inlet 114 in the vertical direction is closer to the polluted air inlet 114 in the horizontal direction than the end farther away from the polluted air inlet 114. Therefore, dust in the air entering the polluted air inlet cavity 118 through the polluted air inlet 114 cannot reach the purification filter 130 during the settling process.

[0045] Please refer to the following: Figure 3 , Figure 3 The image shown is a cross-sectional view of the fresh air module 100 provided in this embodiment in the sewage discharge mode.

[0046] When the air conditioner 200 operates in the sewage discharge mode, the purified air inlet 112 is closed, the polluted air inlet 114 is open, and the air outlet switching component 180 blocks the connection between the fresh air inlet 119 and the fresh air intake chamber 117, and connects the air outlet 1112 of the fan chamber 111 to the outdoor exhaust vent 113. In this state, the fan 120 rotates, drawing indoor air into the polluted air intake chamber 118 through the polluted air inlet 114, and then into the fan chamber 111 through the air inlet 1111, and finally out through the outdoor exhaust vent 113 to the outside, thus achieving the discharge of polluted indoor air.

[0047] As can be seen, the fresh air module 100 provided in this embodiment has fresh air function, purification function and sewage discharge function, which can meet multiple functional needs and provide a better user experience.

[0048] In this embodiment, the purification filter 130 is disposed vertically above the fresh air filter 140. The vertical projection of the purification filter 130 onto the plane containing the fresh air filter 140 at least partially coincides with the fresh air filter 140. The angle between the plane containing the purification filter 130 and the horizontal plane is greater than 0° and less than 90°. The plane containing the fresh air filter 140 is parallel to the horizontal plane. The left side wall of the purification filter 130 is part of the side wall forming the purification air inlet cavity 116. The right side wall of the purification filter 130 and the upper side wall of the fresh air filter 140 are both part of the side walls forming the polluted air inlet cavity 118. The lower side wall of the fresh air filter 140 is part of the side wall forming the fresh air inlet cavity 117.

[0049] As can be seen, in this embodiment, the purified air inlet chamber 116 and the polluted air inlet chamber 118 are arranged roughly horizontally, with the fresh air inlet chamber 117 located vertically below both the purified air inlet chamber and the polluted air inlet chamber 118. Therefore, the inclined arrangement of the purified filter 130 and the horizontal arrangement of the fresh air filter 140 improves the space utilization of the air inlet chamber of the housing 110. Furthermore, the inclined arrangement of the purified filter 130 above the fresh air filter 140 greatly increases the flow area within the limited space, thereby improving the purification effect on indoor air without obstructing the fresh air filter 140 and avoiding hindering the purification of fresh air.

[0050] In this embodiment, the fresh air inlet 119 is located below the housing 110 and communicates with the fresh air inlet cavity 117 to facilitate connection of the fresh air duct. The purification air inlet 112 and the waste air inlet 114 are both located on the top wall of the housing 110. In either purification mode or waste discharge mode, they can suck away dust from the top wall of the housing 110, thereby achieving automatic cleaning of the top wall of the housing 110.

[0051] Furthermore, a movable baffle 150 is slidably provided on the top wall of the housing 110. The movable baffle 150 is used to slide horizontally relative to the housing 110 under the action of external force to open one of the purification air inlet 112 and the sewage air inlet 114, or to close the purification air inlet 112 and the sewage air inlet 114 at the same time.

[0052] In this embodiment, the purified air inlet 112 is positioned to the left of the polluted air inlet 114. In fresh air mode, the movable baffle 150 simultaneously closes both the purified air inlet 112 and the polluted air inlet 114. In purification mode, the movable baffle 150 slides to the right to open the purified air inlet 112 while keeping the polluted air inlet 114 closed. In sewage discharge mode, the movable baffle 150 slides to the left to open the polluted air inlet 114 and close the purified air inlet 112.

[0053] In practical applications, the air conditioner 200 is equipped with a drive device to drive the movable baffle 150 to slide left and right. This drive device responds to the control of the air conditioner 200, thereby controlling the movable baffle 150 to move to different positions when the air conditioner 200 switches between different modes. It is understood that in other embodiments, the opening and closing control of the purified air inlet 112 and the waste air inlet 114 can also adopt other devices or structures. For example, two separate control valves can be used to achieve individual control of the purified air inlet 112 and the waste air inlet 114.

[0054] Considering that in practical applications, the purification filter 130 and the fresh air filter 140 need to be cleaned or replaced regularly, requiring disassembly and reassembly, in order to facilitate the disassembly and reassembly of the purification filter 130 and the fresh air filter 140 on the housing 110, in this embodiment, both the purification filter 130 and the fresh air filter 140 are engaged with the housing 110 by a pull-in method.

[0055] In fact, a first mounting hole is provided on the side wall of the housing 110, and a first guide slide assembly 160 is provided on the inner side wall of the housing 110. The first guide slide assembly 160 corresponds to the position of the first mounting hole and extends from the first mounting hole to the inner wall of the housing 110. The purification filter 130 extends into the housing 110 through the first mounting hole and slides in cooperation with the first guide slide assembly 160. Under the action of external force, the purification filter 130 can slide out of the housing 110 along the first guide slide assembly 160 through the first mounting hole to clean or replace the purification filter 130, and can slide back into the housing 110 through the first mounting hole along the first guide slide assembly 160 to achieve quick installation of the purification filter 130.

[0056] Similarly, a second mounting hole is provided on the side wall of the housing 110, and a second guide sliding assembly 170 is provided on the inner side wall of the housing 110. The second guide sliding assembly 170 corresponds to the position of the second mounting hole and extends from the second mounting hole to the inner wall of the housing 110. The fresh air filter 140 extends into the housing 110 through the second mounting hole and slides in cooperation with the second guide sliding assembly 170. Under the action of external force, the fresh air filter 140 can slide out of the housing 110 along the second guide sliding assembly 170 through the second mounting hole to clean or replace the fresh air filter 140, and can slide back into the housing 110 through the second mounting hole along the second guide sliding assembly 170 to achieve quick installation of the fresh air filter 140.

[0057] Please refer to the following: Figure 4 , Figure 5 and Figure 6 , Figure 4 The diagram shown is a structural schematic of the air outlet switching component 180. Figure 5 This is a schematic diagram showing the connection structure between the air outlet switching component 180 and the housing 110 in fresh air mode or purification mode. Figure 6 This is a schematic diagram of the connection structure between the air outlet switching component 180 and the housing 110 in the sewage discharge mode.

[0058] The air outlet switching assembly 180 is provided with a first air guide cavity 181 and a second air guide cavity 182. The first air guide cavity 181 and the second air guide cavity 182 are connected inside the air outlet switching assembly 180. A first rotating baffle 183 is provided on the air outlet switching assembly 180 corresponding to the first air guide cavity 181. The first rotating baffle 183 can be rotated to a position that seals or opens the first air guide cavity 181. A second rotating baffle 184 is provided on the air outlet switching assembly 180 corresponding to the second air guide cavity 182. The second rotating baffle 184 can be rotated to a position that seals or opens the second air guide cavity 182. An opening for connecting to the outside is provided on the cavity wall of the second air guide cavity 182.

[0059] By configuring the position of the air outlet switching component 180 on the housing 110, the first air guide cavity 181 corresponds to the outdoor exhaust vent 113, and the second air guide cavity 182 corresponds to the fresh air vent 119. When the first rotating baffle 183 rotates to the position of opening the first air guide cavity 181, the first rotating baffle 183 covers the indoor air outlet 115, thereby connecting the air outlet 1112 of the fan cavity 111 with the first air guide cavity 181 through the outdoor exhaust vent 113; when the first rotating baffle 183 rotates to the position of covering the first air guide cavity 181, it connects the air outlet 1112 with the indoor air outlet 115. When the second rotating baffle 184 rotates to the position of sealing the second air guide cavity 182, it blocks the fresh air inlet 119 from the fresh air inlet cavity 117; when the second rotating baffle 184 rotates to the position of opening the second air guide cavity 182, it connects the fresh air inlet 119 to the fresh air inlet cavity 117.

[0060] Please refer to the following: Figure 1 , Figure 2 and Figure 3 In fresh air mode, the first rotating baffle 183 rotates to the position of covering the first air guide cavity 181, i.e., covering the outdoor exhaust vent 113, and the second rotating baffle 184 rotates to the position of opening the second air guide cavity 182. At this time, the air outlet 1112 of the fan cavity 111 is connected to the indoor air outlet 115, and the fresh air inlet 119 is connected to the fresh air inlet cavity 117. In purification mode, the first rotating baffle 183 rotates to the position of covering the first air guide cavity 181, and the second rotating baffle 184 rotates to the position of covering the second air guide cavity 182. The air outlet 1112 of the fan cavity 111 is connected to the indoor air outlet 115, while the fresh air inlet 119 is not connected to the fresh air intake cavity 117. In the sewage discharge mode, the first rotating baffle 183 rotates to the position of opening the first air guide cavity 181, and the second rotating baffle 184 rotates to the position of sealing the second air guide cavity 182. At this time, the air outlet 1112 of the fan cavity 111 is connected to the first air guide cavity 181, and the opening on the cavity wall of the second air guide cavity 182 is connected to the first air guide cavity 181 through the second air guide cavity 182, but not connected to the fresh air inlet 119.

[0061] It is understood that in other embodiments, the structure of the air outlet switching component 180 can be adjusted and replaced according to actual application conditions. For example, in an embodiment with only purification mode and sewage discharge mode, it is not necessary to introduce outdoor fresh air, so the air outlet switching component 180 may only have the function of switching the air outlet 1112 to be connected to the outdoor exhaust port 113 or the indoor air outlet 115.

[0062] In summary, the fresh air module 100 provided in this embodiment, in addition to its fresh air function, also has the functions of purifying indoor air and expelling polluted indoor air to the outside, making it applicable to a wider range of scenarios. In practical applications, it can quickly improve indoor air quality and provide a better user experience.

[0063] In addition, this embodiment also provides an air conditioner 200, please refer to [link / reference]. Figure 5 , Figure 5 The diagram shown is a structural schematic of the air conditioner 200.

[0064] The air conditioner 200 provided in this embodiment is equipped with the aforementioned fresh air module 100. In fact, the fresh air module 100 is disposed at one end of the housing 210 of the air conditioner 200. The housing 210 has a first opening 212 corresponding to the purified air inlet 112, a second opening 213 corresponding to the polluted air inlet 114, and a third opening 214 corresponding to the indoor air outlet 115. The first opening 212 and / or the second opening 213 are opened on the top wall of the housing 210, and the third opening 214 is disposed adjacent to the heat exchange air outlet 211 opened on the housing 210.

[0065] Understandably, the heat exchange outlet 211 is used to blow the airflow after heat exchange from the air conditioner 200 into the room to regulate the indoor temperature. At least one of the first opening 212 and the second opening 213 is located on the top wall of the casing 210, enabling automatic cleaning of dust from the top wall of the casing 210. The first mounting hole and the second mounting hole are correspondingly installed on the side wall of the casing 210, allowing for quick installation and removal of the purification filter 130 and the fresh air filter 140 without disassembling the unit. The third opening 214 is located adjacent to the heat exchange outlet 211 on the casing 210, allowing the purified exhaust air or fresh air exhaust to quickly mix with the exhaust air from the heat exchange outlet 211, improving user comfort.

[0066] In summary, the air conditioner 200 provided in this embodiment, in addition to its fresh air function, also has the functions of purifying indoor air and expelling polluted indoor air to the outside, making it applicable to a wider range of scenarios. In practical applications, it can quickly improve indoor air quality and provide a better user experience.

[0067] While the present invention has been disclosed above, it is not limited thereto. Any person skilled in the art can make various modifications and alterations without departing from the spirit and scope of the invention; therefore, the scope of protection of the present invention should be determined by the scope defined in the claims.
