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 existing fresh air modules have limited functionality and poor user experience.

[0004] To address the aforementioned issues, this invention provides a fresh air module that simultaneously possesses both fresh air and purification 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, a purification filter, and a fresh air filter. The housing has an air inlet chamber and a fan chamber. The housing has a purification air inlet, a fresh air inlet, and an indoor air outlet. The fan is installed in the fan chamber, and the indoor air outlet is connected to the fan chamber.

[0007] Both the purification filter and the fresh air filter are installed inside the air inlet cavity, dividing the air inlet cavity into a purification air inlet cavity, a fresh air inlet cavity, and a transition air cavity. The purification filter is used to purify the airflow flowing from the purification air inlet cavity into the transition air cavity, and the fresh air filter is used to purify the airflow flowing from the fresh air inlet cavity into the transition air cavity. The transition air cavity is connected to the fan cavity, the purification air inlet is connected to the purification air inlet cavity, and the fresh air inlet is connected to the fresh air inlet cavity.

[0008] The fresh air module provided in this invention embodiment can operate in fresh air mode and / or purification mode in practical applications. In fresh air mode, the fan operates, drawing outdoor fresh air into the fresh air inlet cavity through the fresh air inlet, filtering it through the fresh air filter, and then into the transition air cavity. Finally, it is drawn into the fan cavity from the transition air cavity and discharged into the room through the indoor air outlet. In purification mode, the fan operates, drawing indoor air into the purification inlet cavity through the purification inlet, filtering it through the purification filter, and then into the transition air cavity. Finally, it is drawn into the fan cavity from the transition air cavity and discharged into the room through the indoor air outlet, thus purifying the indoor air. Therefore, the fresh air module provided in this invention embodiment has both fresh air function and indoor air purification function, resulting in a better user experience.

[0009] In an optional embodiment, the angle between the air inlet surface of the purification filter and the horizontal plane is greater than 0° and less than 90°, the left side wall of the purification filter serves as a partial side wall defining the purification air inlet cavity, and the right side wall of the purification filter serves as a partial side wall defining the transition air cavity.

[0010] In this embodiment, the purification filter has a plate-like structure. The air inlet surface of the purification filter refers to the plane on which the purification filter is located. The angle between the plane and the horizontal plane is greater than 0° and less than 90°. That is, the purification filter is set at an angle to increase the flow area and improve the purification effect.

[0011] In an optional embodiment, the air inlet surface of the fresh air filter is parallel to the horizontal plane, the upper sidewall of the fresh air filter serves as a partial sidewall defining the transition air cavity, and the lower sidewall of the fresh air filter serves as a partial sidewall defining the fresh air inlet cavity.

[0012] In an optional embodiment, the angle between the air inlet surface of the purification filter and the horizontal plane is greater than 0° and less than 90°, the air inlet surface of the fresh air filter is parallel to the horizontal plane, the left side wall of the purification filter serves as a partial side wall defining the purification air inlet cavity, the right side wall of the purification filter and the upper side wall of the fresh air filter both serve as partial side walls defining the transition air cavity, and the lower side wall of the fresh air filter serves as a partial side wall defining the fresh air inlet cavity.

[0013] The purification filter is angled above the fresh air filter, saving internal space and ensuring it doesn't obstruct the fresh air filter, thus preventing obstruction of fresh air purification. Furthermore, the lower sidewall of the fresh air filter partially defines the fresh air intake chamber, which is located relatively below the housing. This allows the fresh air inlet to be positioned below the housing, facilitating easy connection to the fresh air duct.

[0014] In an optional embodiment, the purified air inlet chamber is located above the fresh air inlet chamber, and the vertical projection of the purified filter on the air inlet surface of the fresh air filter at least partially coincides with the fresh air filter.

[0015] The purification air inlet chamber is located above the fresh air inlet chamber. By tilting the purification filter, indoor air purification and fresh air purification do not interfere with each other, improving the utilization rate of the internal space of the casing while ensuring the purification effect.

[0016] In an optional embodiment, the purification air inlet is located on the top wall of the housing, and the purification air inlet is provided with a movable baffle, which is used to open or close the purification air inlet under the action of external force.

[0017] The top wall of the casing corresponds to the top wall of the indoor unit, and the purification 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. Furthermore, by sliding the movable baffle horizontally, the purification air inlet can be opened or closed, thereby controlling the start and stop of the purification function.

[0018] In an optional embodiment, a first mounting hole is provided on the side wall of the housing, and a first guide slide assembly is provided on the inner side wall of the housing. The purification filter extends into the air inlet cavity through the first mounting hole and slides in cooperation 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, a second mounting hole is provided on the side wall of the housing, and a second guide slide assembly is provided on the inner side wall of the housing. The fresh air filter extends into the air inlet cavity through the second mounting hole and slides in cooperation with the second guide slide assembly.

[0021] Similarly, the fresh air filter slides into or out of the housing through the second mounting hole along the second guide assembly, making it easy and quick to install and remove, and easy to clean and replace.

[0022] In an optional embodiment, the fresh air inlet is provided with a rotating baffle, which is used to rotate under the action of an external force to open or close the fresh air inlet.

[0023] The rotating baffle can open or close the fresh air inlet in a vertical plane, thereby controlling the start and stop of the fresh air mode.

[0024] An embodiment of the present invention also provides an air conditioner, including the aforementioned fresh air module. The fresh air module includes a housing, a fan, a purification filter, and a fresh air filter. An air inlet cavity and a fan cavity are respectively provided inside the housing. A purification air inlet, a fresh air inlet, and an indoor air outlet are respectively provided on the housing. The fan is installed in the fan cavity, and the indoor air outlet communicates with the fan cavity. Both the purification filter and the fresh air filter are installed in the air inlet cavity, dividing the air inlet cavity into a purification air inlet cavity, a fresh air inlet cavity, and a transition air cavity. The purification filter is used to purify the airflow flowing from the purification air inlet into the transition air cavity, and the fresh air filter is used to purify the airflow flowing from the fresh air inlet into the transition air cavity. The purification air inlet is connected to the purification air inlet, and the fresh air inlet is connected to the fresh air inlet. A first opening is provided on the housing corresponding to the purification air inlet, and a second opening is provided on the housing corresponding to the indoor air outlet. The first opening is located on the top wall of the housing, and the second opening is adjacent to the heat exchange air outlet on the housing.

[0025] The air conditioner provided in this embodiment of the invention can operate in a fresh air mode and / or a purification mode in practical applications. In fresh air mode, the fan operates, drawing outdoor fresh air into the fresh air intake chamber through the fresh air inlet, filtering it through the fresh air filter, and then into the transition air chamber. Finally, the air is drawn into the fan through the transition air chamber and discharged into the room through the indoor air outlet. In purification mode, the fan operates, drawing indoor air into the purification intake chamber through the purification inlet, filtering it through the purification filter, and then into the transition air chamber. Finally, the air is drawn into the fan through the transition air chamber and discharged into the room through the indoor air outlet, thus purifying the indoor air. Therefore, the air conditioner provided in this embodiment of the invention simultaneously possesses fresh air and indoor air purification functions, resulting in a better user experience.

Detailed Implementation

[0035] 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.

[0036] 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.

[0037] 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, a fresh air inlet 113, a stale air inlet 114, an indoor air outlet 115, and an outdoor air outlet 119. The fan 120 is installed in the fan chamber 111.

[0038] 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 provided on the housing 110. It is used to selectively connect the fresh air inlet 113 to the air inlet cavity, and to connect the air outlet 1112 of the fan cavity 111 to the outdoor exhaust vent 119 or the indoor exhaust vent 115. It is also used to block the connection between the fresh air inlet 113 and the air inlet cavity when the air outlet 1112 is connected to the outdoor exhaust vent 119.

[0039] Both the purification filter 130 and the fresh air filter 140 are installed in the air inlet cavity, which is divided into a purification air inlet cavity 116, a fresh air inlet cavity 117, and a transition air cavity 118. The purification air inlet cavity 116 is connected to the transition air cavity 118 through the purification filter 130. The fresh air inlet cavity 117 is connected to the transition air cavity 118 through the fresh air filter 140. The transition air 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 113 is connected to the fresh air inlet cavity 117. The waste air inlet 114 is connected to the transition air cavity 118.

[0040] 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 113 with the fresh air intake chamber 117 and connects the air outlet 1112 of the fan chamber 111 with 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 113. 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 transition air 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.

[0041] 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.

[0042] 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 113 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 and flows into the transition air cavity 118. Then, it flows into the fan cavity 111 through the air inlet 1111 of the fan cavity 111, and then flows out of the fan cavity 111 through the air outlet 1112 of the fan cavity 111, and flows into the room through the indoor air outlet 115, thus completing the purification of the indoor air.

[0043] 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.

[0044] 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 113 and the fresh air inlet cavity 117, and connects the air outlet 1112 of the fan cavity 111 to the outdoor exhaust vent 119. In this state, the fan 120 rotates, drawing indoor air into the transition air cavity 118 through the polluted air inlet 114, and then into the fan cavity 111 through the air inlet 1111, and then out through the air outlet 1112 of the fan cavity 111 to the outside through the outdoor exhaust vent 119, thus achieving the discharge of indoor polluted air.

[0045] 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.

[0046] In this embodiment, the purification filter 130 is vertically positioned above the fresh air filter 140. The vertical projection of the purification filter 130 onto the air inlet surface of the fresh air filter 140 at least partially coincides with the fresh air filter 140. The angle between the air inlet surface of the purification filter 130 and the horizontal plane is greater than 0° and less than 90°, and the air inlet surface of the fresh air filter 140 is parallel to the horizontal plane. Since both the purification filter 130 and the fresh air filter 140 in this embodiment have a plate-like structure, the plane containing the fresh air filter 140 is parallel to the horizontal plane, and the angle between the plane containing the purification filter 130 and the horizontal plane is greater than 0° and less than 90°. The left side wall of the purification filter 130 partially forms 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 both partially form the transition air cavity 118, and the lower side wall of the fresh air filter 140 partially forms the fresh air inlet cavity 117.

[0047] As can be seen, in this embodiment, the purification air inlet cavity 116 and the transition air cavity 118 are arranged roughly horizontally, with the fresh air inlet cavity 117 located vertically below the purification air cavity and the transition air cavity 118. Therefore, the inclined arrangement of the purification filter 130 and the horizontal arrangement of the fresh air filter 140 improve the space utilization of the air inlet cavity of the housing 110. Furthermore, the inclined arrangement of the purification 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.

[0048] In this embodiment, the fresh air inlet 113 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 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.

[0049] 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.

[0050] 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.

[0051] 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.

[0052] 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.

[0053] 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.

[0054] 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.

[0055] 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.

[0056] 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.

[0057] 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 119, and the second air guide cavity 182 corresponds to the fresh air inlet vent 113. 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 119; 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 113 and 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 113 and the fresh air inlet cavity 117.

[0058] 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 119, 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 113 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. At this time, the fan cavity 1111... The air outlet 1112 of fan chamber 1 is connected to the indoor air outlet 115, while the fresh air inlet 113 is not connected to the fresh air inlet 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 fan chamber 111 is connected to the first air guide cavity 181 through the outdoor exhaust vent 119, and the opening on the side 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 is not connected to the fresh air inlet 113.

[0059] 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 fresh air mode, only indoor exhaust is required. Therefore, a rotating baffle can be provided only at the fresh air inlet 113 to selectively control the connection between the fresh air inlet 113 and the fresh air inlet cavity 117.

[0060] 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.

[0061] In addition, this embodiment also provides an air conditioner 200, please refer to [link / reference]. Figure 7 , Figure 7 The diagram shown is a structural schematic of the air conditioner 200.

[0062] 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. A first opening 212 is provided on the top wall of the housing 210 corresponding to the purification air inlet 112, enabling automatic cleaning of dust on the top wall of the housing 210 in purification mode. The first mounting hole and the second mounting hole are correspondingly installed on the side wall of the housing 210, allowing for quick installation and removal of the purification filter 130 and the fresh air filter 140 without disassembling the unit. The second opening 213 on the housing 210 corresponding to the indoor air outlet 115 is located on one side of the heat exchange air outlet 211 on the housing 210, and the second opening 213 is adjacent to the heat exchange air outlet 211, so that the purified exhaust air or fresh air can be quickly mixed with the exhaust air of the heat exchange air outlet 211. Since the heat exchange air outlet 211 is used to blow the airflow after heat exchange of the air conditioner 200 into the room to regulate the indoor temperature, mixing the purified exhaust air or fresh air with the heat exchange airflow and blowing it into the room can improve the user's comfort.

[0063] 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.

[0064] 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.
