Description

Technical Field

[0001] This application relates to the field of home appliance technology, and more particularly to an air conditioner. Background Technology

[0002] Currently, with increasing user demands, fresh air conditioning systems are widely used in daily life. However, the humidity, cleanliness, and other indicators of the outdoor fresh air introduced by these systems often fail to meet user needs, leading to a decline in indoor air quality. Therefore, it is necessary to treat the introduced fresh air.

[0003] A related technology includes a fresh air conditioner, characterized by comprising: a heat exchanger housing and a fresh air treatment module. The air inlet of the heat exchanger housing is connected to the air outlet of the fresh air treatment module, and the air inlet of the fresh air treatment module is connected to a fresh air duct. Inside the fresh air treatment module, an adsorption module, an ion sterilization module, and a humidification module are arranged sequentially, and the fresh air flowing through the module is treated by the adsorption module, the ion sterilization module, and the humidification module.

[0004] In the process of implementing the embodiments of this disclosure, at least the following problems were found in the related art:

[0005] The inability to flexibly meet users' current air handling needs increases the consumption of air handling consumables and raises costs.

[0006] It should be noted that the information disclosed in the background section above is only used to enhance the understanding of the background of this application, and therefore may include information that does not constitute prior art known to those skilled in the art. Summary of the Invention

[0007] To provide a basic understanding of some aspects of the disclosed embodiments, a brief summary is given below. This summary is not intended as a general commentary, nor is it intended to identify key / important components or describe the scope of protection of these embodiments, but rather as a prelude to the detailed description that follows.

[0008] This disclosure provides an air conditioner that improves indoor air quality while flexibly meeting users' air handling needs, reducing the consumption of air handling consumables, and lowering costs.

[0009] In some embodiments, the air conditioner includes: a housing, an evaporative cooling pad, and a purification module. The housing has a fresh air inlet, a first return air inlet, and a first air outlet; the evaporative cooling pad is movably disposed within the housing and is movable to either block or open the first air outlet; the purification module is disposed within the housing and is capable of purifying the air flowing through it; wherein, within the housing, a first flow channel can be formed that allows air to flow directly from the fresh air inlet to the first air outlet, or a second flow channel that allows air to flow from the fresh air inlet through the purification module to the first air outlet, or a third flow channel that allows air to flow directly from the first return air inlet to the first air outlet, or a fourth flow channel that allows air to flow from the first return air inlet through the purification module to the first air outlet.

[0010] The air conditioner provided in this embodiment can achieve the following technical effects:

[0011] By incorporating movable evaporative cooling pads and a purification module, the internal air conditioning unit can be configured with one of four flow channels—a first, second, third, or fourth—based on the user's air handling needs. In the first flow channel, fresh air is introduced through the fresh air inlet and blown into the room from the first air outlet. In the second flow channel, fresh air is introduced through the fresh air inlet, purified by the purification module, and then blown into the room from the first air outlet. In the third flow channel, indoor air is introduced through the first return air inlet and blown into the room from the first air outlet for internal circulation and heat exchange. In the fourth flow channel, indoor air is introduced through the first return air inlet, purified by the purification module, and then blown into the room from the first air outlet for internal circulation and heat exchange, thus purifying the indoor air. Simultaneously, the movement of the evaporative cooling pads to block or open the first air outlet humidifies the airflow. This improves indoor air quality while flexibly meeting the user's air handling needs, reducing the consumption of air handling consumables and lowering costs.

[0038] It should be noted that, unless otherwise specified, the embodiments and features described in the present disclosure can be combined with each other.

[0039] Combination Figures 1-17 As shown, in some embodiments, the air conditioner includes: a housing 100, a wet curtain 200, and a purification module 300. The housing 100 is provided with a fresh air inlet 101, a first return air inlet 102, and a first air outlet 103; the evaporative cooling pad 200 is movably disposed inside the housing 100, and the evaporative cooling pad 200 can be moved to a position that blocks or opens the first air outlet 103; the purification module 300 is disposed inside the housing 100 and can purify the air flowing through it; wherein, inside the housing 100, a first flow channel 104 can be formed that flows directly from the fresh air inlet 101 to the first air outlet 103, or a second flow channel 105 that flows from the fresh air inlet 101 through the purification module 300 to the first air outlet 103, or a third flow channel 106 that flows directly from the first return air inlet 102 to the first air outlet 103, or a fourth flow channel 107 that flows from the first return air inlet 102 through the purification module 300 to the first air outlet 103.

[0040] The air conditioner provided in this embodiment, by setting a movable wet curtain 200 and a purification module 300, forms one of a first flow channel 104, a second flow channel 105, a third flow channel 106, and a fourth flow channel 107 inside the casing 100 according to the user's air handling needs. When the first flow channel 104 is formed inside the casing 100, the air conditioner can introduce fresh air through the fresh air inlet 101 and blow it into the room from the first air outlet 103. When the second flow channel 105 is formed inside the casing 105, the air conditioner can introduce fresh air through the fresh air inlet 101, and after the fresh air flows through the purification module 300 for purification, it is blown into the room from the first air outlet 103. When the third flow channel 106 is formed inside the casing 106, the air conditioner can introduce indoor air through the first return air inlet 102 and blow it into the room from the first air outlet 103 for internal circulation heat exchange. With a fourth airflow channel 107 formed inside the casing 100, the air conditioner can draw in indoor air through the first return air vent 102. This indoor air is then purified by the purification module 300 and blown into the room through the first air outlet 103 for internal circulation and heat exchange, thus purifying the indoor air. Simultaneously, the movement of the evaporative cooling pad 200 can block or open the first air outlet 103, humidifying the airflow. This improves indoor air quality while flexibly meeting users' air handling needs, reducing the consumption of air handling consumables, and lowering costs.

[0041] The air conditioner in this embodiment has multiple operating modes. When a first flow channel 104 is formed inside the casing 100, the evaporative cooling pad 200 can be driven to block the first air outlet 103, at which point the air conditioner operates in a mode that introduces fresh air and humidifies it. Alternatively, the evaporative cooling pad 200 can be driven to open the first air outlet 103, at which point the air conditioner operates in a mode that introduces fresh air. When a second flow channel 105 is formed inside the casing 100, the evaporative cooling pad 200 can be driven to block the first air outlet 103, at which point the air conditioner operates in a mode that introduces fresh air, purifies it, and humidifies it. Alternatively, the evaporative cooling pad 200 can be driven to open the first air outlet 103, at which point the air conditioner operates in a mode that introduces fresh air and purifies it. When a third flow channel 106 is formed inside the casing 100, the evaporative cooling pad 200 can be moved to the position of blocking the first air outlet 103. At this time, the air conditioner operates in the indoor air recirculation and humidification mode. Alternatively, the evaporative cooling pad 200 can be moved to the position of opening the first air outlet 103. At this time, the air conditioner operates in the indoor air recirculation, purification, and humidification mode. Alternatively, the evaporative cooling pad 200 can be moved to the position of opening the first air outlet 103. At this time, the air conditioner operates in the fresh air introduction and purification mode.

[0042] It is understandable that the position where the wet curtain 200 moves to open the first air outlet 103 means that the wet curtain 200 no longer blocks the first air outlet 103, rather than that the first air outlet 103 was in a closed state before the wet curtain 200 moves. The opening and closing of the first air outlet 103 is related to the panel set on the housing 100, and the opening and closing state of the first air outlet 103 is controlled by the movement of the panel.

[0043] Optionally, the housing 100 is further provided with a second return air inlet 108 and a second air outlet 109, and a heat exchange channel is formed inside the housing 100, through which air flows from the second return air inlet 108 to the second air outlet 109. In this way, indoor air flows into the heat exchange channel through the second return air inlet 108 for heat exchange, and then flows out into the indoor environment from the second air outlet 109, thereby regulating the temperature of the indoor environment.

[0044] Specifically, both the second return air vent 108 and the second air outlet 109 are connected to the indoor environment, and a heat exchange fan and a heat exchanger are installed inside the heat exchange channel. In this way, a negative pressure is formed inside the heat exchange channel under the action of the heat exchange fan, drawing indoor air from the second return air vent 108 and passing it through the heat exchanger for heat exchange. The heated indoor air is then blown out again into the indoor environment through the second air outlet 109, thereby regulating the temperature of the indoor environment.

[0045] Optionally, the housing 100 includes: a first column housing 110, a second column housing 120, and a base 130. The first column housing 110 defines a heat exchange flow channel, and the second return air inlet 108 and the second air outlet 109 are both opened on the side wall of the first column housing 110; the second column housing 120 defines a humidification chamber, and the evaporative cooling pad 200 is movably disposed in the humidification chamber, and the first air outlet 103 is opened on the side wall of the second column housing 120 and communicates with the humidification chamber; the base 130 defines an installation cavity, and the purification module 300 is disposed in the installation cavity, which communicates with the humidification chamber, and the fresh air inlet 101 and the first return air inlet 102 are both communicated with the installation cavity. In this configuration, the casing 100 is divided into a first column housing 110, a second column housing 120, and a base 130. A heat exchange flow channel is defined inside the first column housing 110, and a humidification chamber is defined inside the second column housing 120. An evaporative cooling pad 200 is movably disposed within the humidification chamber. An installation cavity is defined inside the base 130, and a purification module 300 is disposed within the installation cavity. Both purified and non-purified airflow in the installation cavity flow into the humidification chamber. The position of the evaporative cooling pad 200 is then controlled to determine whether the incoming airflow is humidified. The installation cavity and the humidification chamber work together to process the air, while the heat exchange flow channel regulates the temperature of the indoor return air. The first column housing 110 and the second column housing 120 are both independently disposed on the upper side of the base 130. The airflows from the first column housing 110 and the second column housing 120 do not interfere with each other. This improves indoor air quality while reducing the impact of air treatment on the heat exchange airflow delivery effect and increasing the delivery distance.

[0046] Optionally, the first column housing 110 and the second column housing 120 are arranged side by side, and the first column housing 110 and the second column housing 120 have the same height. This makes the overall structure of the air conditioner housing 100 more regular and easier to place.

[0047] Optionally, the first air outlet 103 and the second air outlet 109 are respectively opened on the side wall of the first column shell 110 and the second column shell 120 on the same side. In this way, the airflow blown out of the first air outlet 103 and the heat exchange airflow blown out of the second air outlet 109 can be blown out in the same direction, and the two can mix, thereby improving the mixing effect and improving the air supply effect.

[0048] Optionally, the first air outlet 103 and the second air outlet 109 are located in the same plane. This allows the airflow from the first air outlet 103 to mix better with the heat exchange airflow from the second air outlet 109, improving the air mixing effect.

[0049] Optionally, the height of the first air outlet 103 is the same as the height of the second air outlet 109. This allows the airflow from the first air outlet 103 to mix better with the heat exchange airflow from the second air outlet 109, improving the air mixing effect.

[0050] Optionally, a guide vane is provided on the inner side of the second air outlet 109. Under the action of the guide vane, the air outlet direction of the second air outlet 109 can be shifted towards the first air outlet 103. In this way, guided by the guide vane, the heat exchange airflow blown out of the second air outlet 109 is shifted towards the airflow blown out of the first air outlet 103. The heat exchange airflow blows onto the air curtain formed by the first air outlet 103, and the two can be further mixed to improve the air mixing effect.

[0051] Optionally, the air outlet area of ​​the second air outlet 109 is larger than that of the first air outlet 103. Since the second air outlet 109 is connected to the heat exchange channel within the first column housing 110, and blows out heat exchange airflow from the second air outlet 109, and temperature regulation in the indoor environment relies on this heat exchange airflow, setting the air outlet area of ​​the second air outlet 109 to be larger than that of the first air outlet 103 improves indoor air quality while ensuring effective temperature regulation.

[0052] Optionally, the air conditioner also includes a water tank 400. The water tank 400 is disposed inside the casing 100 and located above the evaporative cooling pad 200, for supplying water to the evaporative cooling pad 200. Thus, by supplying water to the evaporative cooling pad 200 through the water tank 400, the evaporative cooling pad 200 is continuously moistened. When the evaporative cooling pad 200 moves to a position blocking the first air outlet 103, the airflow blowing out of the first air outlet 103 accelerates the evaporation of water from the evaporative cooling pad 200, improving the humidification effect. Positioning the water tank 400 above the evaporative cooling pad 200 allows the water in the water tank 400 to drip naturally onto the evaporative cooling pad 200 using gravity, eliminating the need for a water pump or similar structure and reducing costs.

[0053] Optionally, the water tank 400 is disposed in the humidification chamber inside the second column housing 120. An inspection port is provided on the side wall of the second column housing 120 corresponding to the position of the water tank 400, and a removable panel is provided on the inspection port. In this way, the water tank 400 can be inspected through the inspection port by removing the panel, without disassembling the water tank 400, thus improving the inspection efficiency of the water tank 400.

[0054] Optionally, a water inlet box 210 is provided above the evaporative cooling pad 200. The water inlet box 210 is located between the water tank 400 and the upper surface of the evaporative cooling pad 200. Water in the water tank 400 flows into the water inlet box 210 and then flows to the upper surface of the evaporative cooling pad 200. In this way, by setting the water inlet box 210 at the upper end of the evaporative cooling pad 200, water droplets from the water tank 400 are dripped onto the upper end of the evaporative cooling pad 200, wetting the evaporative cooling pad 200. The airflow from the first air outlet 103 accelerates the evaporation of the evaporative cooling pad 200, thereby humidifying. By dripping humidifying water onto the upper end of the evaporative cooling pad 200, the uniformity of wetting of the entire evaporative cooling pad 200 can be improved, thus improving the humidification effect.

[0055] Optionally, the water supply box 210 is internally provided with a water supply tank 220, a heating tank 230, and a buffer tank 240. The water supply tank 220 is located above the heating tank 230, and the heating tank 230 is located above the buffer tank 240. The evaporative cooling pad 200 is located below the water supply box 210, with its upper surface directly below the water supply box 210. Water from the water supply tank 220 flows into the heating tank 230, where it is heated and overflows into the buffer tank 240. Then, it flows along the buffer tank 240 to the upper surface of the evaporative cooling pad 200. Thus, by providing the water supply tank 220, heating tank 230, and buffer tank 240 internally, the water from the water supply tank 220 first flows into the heating tank 230, is heated, overflows into the buffer tank 240, and then flows to the evaporative cooling pad 200, wetting it. The water from the evaporative cooling pad 200 is then used for evaporative humidification. By setting up a heating tank 230 to heat the water flowing into the water supply tank 220, that is, only the humidifying water flowing to the wet curtain 200 is heated, and the amount of water heated is small, thereby reducing heating energy consumption and improving heating efficiency.

[0056] Optionally, the water tank 210 is further provided with a drip tray 250, which is located below the buffer tank 240 and is connected to the buffer tank 240. A drain hole 251 is provided on the lower side wall of the drip tray 250, and the upper end of the evaporative cooling pad 200 is located directly below the drain hole 251. In this way, water from inside the buffer tank 240 flows into the drip tray 250 and drips onto the upper end of the evaporative cooling pad 200 through the drain hole 251 on the lower side wall of the drip tray 250, improving the uniformity of wetting of the evaporative cooling pad 200.

[0057] Optionally, the lower side wall of the drip tray 250 is fitted over the upper end of the evaporative cooling pad 200, and the shape of the lower side wall of the drip tray 250 is adapted to the shape of the upper end face of the evaporative cooling pad 200. In this way, the water in the drip tray 250 drips more evenly onto the upper end face of the evaporative cooling pad 200, improving the uniformity of wetting of the evaporative cooling pad 200, thereby improving the humidification effect.

[0058] Optionally, the lower side wall of the drip tray 250 is provided with a plurality of drainage holes 251, which are evenly distributed on the lower side wall of the drip tray 250. In this way, the water in the drip tray 250 is dripped more evenly onto the upper surface of the wet curtain 200, thereby improving the uniformity of wetting of the wet curtain 200.

[0059] Optionally, the lower side wall of the buffer tank 240 is provided with a connecting hole 241, through which the buffer tank 240 is connected to the dripping tank 250. In this way, water in the buffer tank 240 flows into the dripping tank 250 along the connecting hole 241.

[0060] Optionally, a drain box 260 is provided below the evaporative cooling pad 200. Water flowing out of the upper water box 210 flows along the evaporative cooling pad 200 into the drain box 260, and the lower end of the evaporative cooling pad 200 is submerged in the water in the drain box 260. In this way, the drain box 260 can collect the water flowing down along the evaporative cooling pad 200, and at the same time, the lower end of the evaporative cooling pad 200 is submerged in the drain box 260, and the lower end of the evaporative cooling pad 200 absorbs water from the drain box 260, further improving the uniformity of wetting of the evaporative membrane and improving the humidification effect.

[0061] Optionally, a drive frame 290 is provided in the drain box 260, and the drive frame 290 is rotatably connected to the lower inner wall of the drain box 260. The lower end of the wet curtain 200 is mounted on the upper side of the drive frame 290. In this way, the drive frame 290 drives the wet curtain 200 to rotate, thereby moving the wet curtain 200 to a position that blocks the first air outlet 103 or opens the first air outlet 103.

[0062] Optionally, a drive assembly 291 is provided on the lower side wall of the drain box 260, and the output end of the drive assembly 291 passes through the lower side wall of the drain box 260 and is connected to the drive frame 290. In this way, the drive assembly 291 drives the drive frame 290 to rotate, thereby driving the wet curtain 200 to rotate.

[0063] Optionally, the drive component 291 is a drive motor.

[0064] Optionally, the air conditioner also includes a water level float 270. The lower end of the water level float 270 is movably disposed within the drain box 260, and the upper end extends movably into the upper water box 210, located directly below the connecting hole 241. When the water level float 270 rises with the water level in the drain box 260, the upper end of the water level float 270 extends into the connecting hole 241 and blocks it. Thus, water dripping onto the wet curtain 200 flows along the wet curtain 200 into the drain box 260, immersing the lower end of the wet curtain 200 in the water within the drain box 260. When the water level in the drain box 260 rises, the water level float 270 rises with the water level in the drain box 260, and the upper end of the water level float 270 blocks the connecting hole 241, preventing water in the water supply tank 220 from flowing into the drip tray 250. During the evaporation process of the wet curtain 200, as the humidifying water in the lower water box 260 is consumed, the water level drops, and the water level float 270 also drops accordingly. The upper end of the water level float 270 detaches from the connecting hole 241, and the water in the water supply tank 220 flows back to the drip tank 250 along the connecting hole 241. Through the cooperation of the upper water box 210, the lower water box 260, and the water level float 270, the water supply structure of this humidification device is simplified, and the humidification cost is reduced.

[0065] Optionally, a connecting pipe 280 is provided between the upper water box 210 and the lower water box 260. The lower end of the connecting pipe 280 is connected to the inner wall of the lower water box 260, and the upper end of the connecting pipe 280 is connected to the upper water box 210. In this way, the connecting pipe 280 connects the upper water box 210 and the lower water box 260 to form a whole, and the connecting pipe 280 provides support for the upper water box 210 and the lower water box 260, thereby improving the installation stability of the upper water box 210 and the lower water box 260.

[0066] Optionally, the connecting pipe 280 has an internal cavity, and the water level float 270 is rod-shaped. The water level float 270 passes through the connecting pipe 280, with its upper end protruding through the upper port of the connecting pipe 280, and its lower port communicating with the interior of the drain box 260. In this way, by installing the water level float 270 using the connecting pipe 280, the connecting pipe 280 can guide the water level float 270, causing it to rise and fall vertically, thus more accurately reflecting the water level in the drain box 260. This allows for more precise sealing of the connecting hole 241, or more accurately removal from the connecting hole 241.

[0067] Optionally, the lower end of the connecting pipe 280 is provided with a water inlet, and the cavity inside the connecting pipe 280 is connected to the drain box 260 through the water inlet. In this way, water in the drain box 260 can flow into the cavity through the water inlet, and the water level in the cavity can rise or fall with the water level in the drain box 260.

[0068] Optionally, a conical plug 271 is formed at the upper end of the water level float 270. When the water level float 270 rises with the water level in the lower water box 260, the conical plug 271 extends into the connecting hole 241 and seals it. In this way, the upper end of the water level float 270 uses the conical plug 271 to better seal the connecting hole 241, improving the sealing effect of the connecting hole 241.

[0069] Optionally, the lower end of the water tank 400 is provided with a water tank cover 410, and the water supply tank 220 is provided with a cover seat 221. The water tank cover 410 is located inside the water supply tank 220, and the cover is movable on the cover seat 221. In this way, the water tank cover 410 itself can form a liquid seal effect, preventing excessive water from the water tank 400 from flowing into the water supply tank 220, thereby supplying water evenly to the water supply tank 220. At the same time, the cooperation between the water level float 270 and the water tank cover 410 forms a double liquid seal structure to achieve uniform and stable water supply to the evaporative cooling pad 200, improving the stability of the humidification water supply of the evaporative cooling pad 200.

[0070] Optionally, the vertical sidewalls of the heating tank 230 and the buffer tank 240 adjacent to each other are lower than the other vertical sidewalls of the heating tank 230. This allows water in the heating tank 230 to overflow into the buffer tank 240 when it is full.

[0071] Optionally, a heating plate 231 is laid on the lower inner wall of the heating tank 230. In this way, the water in the heating tank 230 is heated by the heating plate 231, so that the water overflowing into the buffer tank 240 is hot water, thereby improving the humidification effect of the wet curtain 200.

[0072] Optionally, the area of ​​the heating tank 230 is larger than the area of ​​the buffer tank 240. This increases the water volume in the heating tank 230, ensuring that sufficient heated water overflows into the buffer tank 240.

[0073] Optionally, the area of ​​the heating plate 231 is the same as the area of ​​the lower inner wall of the heating tank 230. In this way, the heating plate 231 covers the entire lower inner wall of the heating tank 230, ensuring the heating effect of the humidifying water in the heating tank 230, thereby ensuring the humidification effect of the evaporative cooling pad 200.

[0074] Optionally, the heating plate 231 includes a heat-conducting substrate and a heating wire. The heat-conducting substrate is laid on the lower inner wall of the heating tank 230, and the heating wire is laid on the lower side wall of the heat-conducting substrate. In this way, the heat from the heating wire is conducted to the heating tank 230 through the heat-conducting substrate. The heat-conducting substrate can increase the heat transfer area with the water in the heating tank 230, improve the heating effect, and reduce energy consumption.

[0075] Optionally, the housing 100 includes an air handling unit 500, with the purification module 300 housed inside. A fresh air inlet 101 and a first return air inlet 102 are located on the side wall of the air handling unit 500. A first flow channel 104, a second flow channel 105, a third flow channel 106, and a fourth flow channel 107 formed inside the housing 100 all flow through the air handling unit 500. In this way, the air handling unit 500 can meet the air supply requirements and simultaneously treat the flowing air, improving the indoor air quality and meeting user needs.

[0076] Optionally, the air handling unit 500 is disposed in a mounting cavity inside the base 130.

[0077] Optionally, the air handling unit 500 is internally divided into a first cavity 520 and a second cavity 530 by a partition 510. A connecting port 511 is provided on the partition 510, through which the purification module 300 passes. Airflow in the first cavity 520 flows into the second cavity 530 via the connecting port 511 and the purification module 300. Both the fresh air inlet 101 and the first return air inlet 102 are connected to the first cavity 520. Thus, by separating the first cavity 520 and the second cavity 530 inside the unit using a partition 510, and by providing a connecting port 511 on the partition 510 through which the purification module 300 passes, when the connecting port 511 is open, most of the airflow in the first cavity 520 flows into the second cavity 530 along the connecting port 511; when the connecting port 511 is closed, the airflow in the first cavity 520 flows into the second cavity 530 along the purification module 300. When the user needs to introduce and purify fresh air, the fresh air inlet 101 opens, the first return air inlet 102 and the connecting port 511 close, and fresh air flows from the fresh air inlet 101 into the first cavity 520, along the purification module 300 into the second cavity 530, and out through the exhaust vent. When the user needs to introduce fresh air without purification, the fresh air inlet 101 and the connecting port 511 open, the first return air inlet 102 closes, and fresh air flows from the fresh air inlet 101 into the first cavity 520, with most of the fresh air flowing into the second cavity 530 along the connecting port 511. When the user needs to purify the indoor air, the fresh air inlet 101 and the connecting port 511 close, the first return air inlet 102 opens, and indoor air flows into the first cavity 520 through the first return air inlet 102, along the purification module 300 into the second cavity 530. When the user needs to promote indoor air circulation but does not require purification, the fresh air inlet 101 closes, and the first return air inlet 102 and the connecting port 511 open. Indoor air flows into the first cavity 520 through the first return air inlet 102, and most of the indoor air flows into the second cavity 530 along the connecting port 511. By coordinating the opening and closing of the fresh air inlet 101, the first return air inlet 102, and the connecting port 511, various user needs can be met, including introducing fresh air and purifying it, introducing fresh air without purification, circulating and purifying indoor air, and circulating indoor air. This simplifies the structure of the air purification device, reduces the wear and tear on the purification module 300, and better meets the diverse needs of users.

[0078] Optionally, a fan 540 is provided on the upper side wall of the air handling unit 500. The air inlet of the fan 540 is connected to the second cavity 530, and the air outlet of the fan 540 is connected to the first air outlet 103. In this way, the fan 540 can provide negative pressure, which creates negative pressure in the second cavity 530 under the action of the fan 540. This causes the airflow in the first cavity 520 to flow into the second cavity 530, and the airflow in the second cavity 530 flows to the first air outlet 103 under the action of the fan 540.

[0079] Specifically, the air outlet of fan 540 is connected to the humidification chamber.

[0080] Optionally, when the fresh air inlet 101 and the connecting port 511 are open, and the first return air inlet 102 is closed, a first flow channel 104 is formed inside the casing 100; when the fresh air inlet 101 is open, and the connecting port 511 and the first return air inlet 102 are closed, a second flow channel 105 is formed inside the casing 100; when the first return air inlet 102 and the connecting port 511 are open, and the fresh air inlet 101 is closed, a third flow channel 106 is formed inside the casing 100; and when the first return air inlet 102 is open, the connecting port 511 and the fresh air inlet 101 are closed, a fourth flow channel 107 is formed inside the casing 100. Thus, when the first flow channel 104 is formed inside the casing 100, fresh air from the external environment flows into the first cavity 520 along the fresh air inlet 101, then flows into the second cavity 530 along the connecting port 511, and then flows to the first air outlet 103. At this time, the air conditioner operates in a mode where fresh air is introduced without purification. When a second flow channel 105 is formed inside the casing 100, fresh air from the external environment flows into the first cavity 520 through the fresh air inlet 101, then flows into the second cavity 530 through the purification module 300, and then flows to the first air outlet 103. At this time, the air conditioner operates in a mode that introduces and purifies fresh air. When a third flow channel 106 is formed inside the casing 100, indoor air flows into the first cavity 520 through the first return air inlet 102, then flows into the second cavity 530 through the connecting opening 511, and then flows to the first air outlet 103. At this time, the air conditioner operates in an indoor air circulation mode. When a fourth flow channel 107 is formed inside the casing 100, indoor air flows into the first cavity 520 through the first return air inlet 102, then flows into the second cavity 530 through the purification module 300, and then flows to the first air outlet 103. At this time, the air conditioner operates in an indoor air circulation and purification mode.

[0081] Optionally, the connecting opening 511 is composed of multiple first connecting gaps 512 arranged together. A first grille plate 513 is provided on the upper side of the connecting opening 511. The first grille plate 513 is movably arranged, capable of simultaneously blocking multiple first connecting gaps 512 or simultaneously opening multiple first connecting gaps 512. In this way, by setting the connecting opening 511 as an orifice-shaped structure composed of multiple first connecting gaps 512, and using the movement of the first grille plate 513 to block or open the connecting opening 511, the blocking and opening of the connecting opening 511 can be achieved within a small range of movement of the first grille plate 513, reducing the space occupied by the movement of the first grille plate 513 and facilitating the installation of the air handling unit 500 inside the air conditioner housing 100.

[0082] For example, the driving mechanism of the first grid plate 513 consists of a rack and a motor. The rack is connected to the first grid plate 513, and the output end of the motor meshes with the rack through a gear. The motor drives the rack to move, thereby driving the first grid plate 513 to move.

[0083] Optionally, a sealing plate 550 is provided inside the fresh air inlet 101. The sealing plate 550 is rotatable, allowing the fresh air inlet 101 to be opened or closed. This arrangement, with the sealing plate 550 inside the fresh air inlet 101 and its rotation used to open and close the inlet, reduces the space occupied by the sealing plate 550 and facilitates the installation of the air handling unit 500 inside the air conditioner housing 100.

[0084] Optionally, the fresh air inlet 101 has a circular opening structure, and the sealing plate 550 has a circular plate structure. A rotating shaft 560 is provided on the sealing plate 550, which is arranged along the diameter of both the sealing plate 550 and the fresh air inlet 101. The two ends of the rotating shaft 560 are rotatably connected to the inner walls of both sides of the fresh air inlet 101. In this way, the sealing plate 550 only needs to rotate 90° to open or close the fresh air inlet 101, reducing the rotation angle of the sealing plate 550. The sealing plate 550 can open and close the fresh air inlet 101 with a relatively small rotation angle, reducing the space required for the rotation of the sealing plate 550, thereby further reducing the space occupied by the sealing plate 550.

[0085] Optionally, the sealing plate 550 is driven by a motor, which is located on the outer wall of the fresh air inlet 101, and the output shaft of the motor is fixedly connected to the end of the rotating shaft 560. In this way, driving the rotation of the sealing plate 550 by a motor improves the rotational stability of the sealing plate 550.

[0086] Optionally, the first return air vent 102 is composed of multiple second connecting gaps 570 arranged together. A second grille plate 580 is provided on the outer side of the first return air vent 102. The second grille plate 580 is movable and can simultaneously block or open multiple second connecting gaps 570. In this way, by setting the first return air vent 102 as an orifice-shaped structure composed of multiple second connecting gaps 570, and using the movement of the second grille plate 580 to block or open the first return air vent 102, the blocking and opening of the first return air vent 102 can be achieved within a small range of movement of the second grille plate 580, reducing the space occupied by the movement of the second grille plate 580 and facilitating the installation of the air handling unit 500 inside the air conditioner housing 100.

[0087] Optionally, the fresh air inlet 101 and the first return air inlet 102 are located on the same side wall of the housing, and the connecting port 511 is located on the windward side of the purification module 300 along the air inlet direction of the fresh air inlet 101 and the first return air inlet 102. In this way, when the connecting port 511 is open, the airflow flowing into the first cavity 520 along the fresh air inlet 101 or the first return air inlet 102 can preferentially flow into the second cavity 530 along the connecting port 511. When there is no need to purify the airflow, the airflow flowing from the purification module 300 into the second cavity 530 is reduced, ensuring that most of the airflow in the first cavity 520 can flow to the second cavity 530 along the connecting port, thereby reducing the loss of the purification module 300.

[0088] Optionally, the purification module 300 includes a dust filtration section 310, a formaldehyde removal section 320, and an odor removal section 330. In this way, the purification module 300 can filter dust, remove formaldehyde, and remove odors from the airflow, improving the purification effect of the airflow and thus improving the air quality of the indoor environment.

[0089] Optionally, the dust filtration section 310, the formaldehyde removal section 320, and the odor removal section 330 are arranged sequentially along the airflow direction. In this way, the airflow passing through the purification module 300 is first filtered by dust, and then formaldehyde and odor removal are performed, reducing the risk of dust in the airflow clogging the formaldehyde removal section 320 and the odor removal section 330, and reducing the wear and tear on the formaldehyde removal section 320 and the odor removal section 330.
