[0032] It should also be understood that the terms used in this specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. As used in the specification of the present invention and the appended claims, unless the context clearly indicates otherwise, the singular forms "a", "an" and "the" are intended to include plural forms.

[0033] It should be further understood that the term "and / or" used in the present description and the appended claims refers to any and all possible combinations of one or more of the associated listed items, and includes these combinations.

[0034] Please also refer to Figure 1-Figure 7 . The air supply structure provided in the embodiment of the present invention is applicable to an air conditioner 400, and the air conditioner 400 includes a main air duct 600. The air supply structure includes: a chassis 100, the chassis 100 has a first cavity 110 and a second cavity 120, the first cavity 110 is provided with a first air outlet 130, and the first air outlet 130 is connected to the main air duct 600; a fresh air module 200, the fresh air module 200 is horizontally installed in the second cavity 120, and the fresh air module 200 has a second air outlet 240; and a fresh air channel 300, the fresh air channel 300 is arranged in the chassis 100, one end of the fresh air channel 300 is connected to the second air outlet 240, and the other end extends to the first cavity 110 and is connected to the first air outlet 130, so that the fresh air delivered by the fresh air module 200 and the supply air of the main air duct 600 are mixed at the first air outlet 130.

[0035] In this embodiment, if Figure 1As shown, the chassis 100 is used as a basic bearing member, and its interior is divided into a first cavity 110 and a second cavity 120. A first air outlet 130 is provided on the first cavity 110 of the chassis 100, and the first air outlet 130 is connected to the main air duct 600 of the air conditioner 400, so as to realize the air supply of the air conditioner 400 to the room. Specifically, the top wall of the first cavity 110 is through-set from top to bottom, and the through-point is connected to the main air duct 600, so that the main air duct 600 is connected to the first air outlet 130 on the front wall of the first cavity 110, ensuring the connectivity of the air supply channel.

[0036] The fresh air module 200 is horizontally installed in the second cavity 120 of the chassis 100. This horizontal installation layout design makes the fresh air module 200 occupy a more reasonable space inside the air conditioner 400, and reserves sufficient installation space for other components. The fresh air module 200 is provided with a second air outlet 240 for conveying outdoor air (fresh air) into the room.

[0037] A fresh air channel 300 is provided in the chassis 100, one end of which is connected to the second air outlet 240 of the fresh air module 200, and the other end of which extends to the first cavity 110 and is connected to the first air outlet 130. Through this channel connection design, the fresh air can be combined with the air supply of the main air duct 600 at the first air outlet 130, and then a mixed airflow is formed and sent into the room together. This air supply structure design allows the fresh air and the airflow of the main air duct 600 to be mixed at the first air outlet 130 first, which can reduce the temperature difference between the two airflows, prevent users from feeling the temperature fluctuating, and at the same time, it can also increase the air supply distance of the fresh air with the air supply airflow of the main air duct 600.

[0038] The air supply structure effectively solves the technical problems in the prior art that the fresh air system occupies a large space, the large supply temperature difference between the fresh air and the main air duct 600 leads to poor user experience, and the fresh air supply distance is limited by reasonably arranging the installation position of the fresh air module 200 and the direction of the fresh air channel 300.

[0039] In this embodiment, "horizontal installation" means that the fresh air module 200 is installed in the second cavity 120, and its axial direction (i.e., the axial direction of the drive motor 221) is substantially perpendicular to the ground, so that the centrifugal fan blades 222 can rotate in the horizontal plane. This installation method allows a certain tilt angle, but does not strictly require it to be completely perpendicular to the ground. This can also achieve more compact space utilization and more convenient installation and maintenance.

[0040] In a specific embodiment, the first cavity 110 corresponds to the front area of ​​the chassis 100. A front cover 161 is installed at the first air outlet 130 in the front area, and a wind deflector structure (not shown in the drawings) is designed at the center thereof to guide the air out of the first air outlet 130.

[0041] In one embodiment, if Figure 1 As shown, the first cavity 110 and the second cavity 120 are arranged opposite to each other, and a mounting channel 150 is provided on the second cavity 120 , and the mounting channel 150 is used for the fresh air module 200 to be inserted into the second cavity 120 .

[0042] In this embodiment, the first cavity 110 and the second cavity 120 are distributed front and back in the chassis 100. The second cavity 120 is provided with an installation channel 150, and the design of the installation channel 150 enables the fresh air module 200 to be horizontally inserted and installed in the second cavity 120. This design not only facilitates the installation and disassembly maintenance of the fresh air module 200, but also ensures the stability of the installation. Through the installation channel 150, the fresh air module 200 can be smoothly pushed into or pulled out of the second cavity 120, realizing a quick and convenient installation operation.

[0043] In a specific embodiment, if Figure 6 As shown, the installation channel 150 includes a first installation hole 151 provided on the top wall of the second cavity 120 and a second installation hole 152 provided on the rear wall of the second cavity 120. The first installation hole 151 is located directly above the fresh air module 200 and is used to accommodate the air inlet pipe 230. The width of the second installation hole 152 is greater than the width of the volute 210, and the height is greater than the height of the volute 210, so that the fresh air module 200 (volute 210) can be horizontally pushed in and installed from the rear of the chassis 100. This double-hole design allows the fresh air module 200 to be stably installed and is convenient for installation and maintenance operations.

[0044] In this embodiment, the second cavity 120 corresponds to the rear area of ​​the chassis 100 . A rear cover 162 is installed at the second mounting hole 152 in the rear area to fix the fresh air module 200 in the second cavity 120 .

[0045] In this embodiment, "front and rear distribution" means that when the user faces the first air outlet 130, the area of ​​the chassis 100 close to the user is the front area, and the area away from the user is the rear area; wherein the first cavity 110 is located in the front area, and the second cavity 120 is located in the rear area.

[0046] In one embodiment, if Figure 2 and Figure 6 As shown, the fresh air module 200 includes: a volute 210, a fan 220 disposed in the volute 210, and an air inlet pipe 230 connected to the volute 210; second air outlets 240 are respectively disposed on opposite sides of the volute 210.

[0047] In this embodiment, the volute 210 is used to form a channel for fresh air flow, and the volute 210 is provided with second air outlets 240 on opposite sides thereof. This double-sided air outlet design allows fresh air to be delivered in two directions at the same time, which is beneficial to the distribution and diffusion of fresh air.

[0048] The air inlet pipe 230 is installed above the volute 210 and communicates with the inside of the volute 210 to construct an air inlet passage for outdoor air (fresh air). A fan 220 is arranged inside the volute 210. The rotation of the fan 220 can generate negative pressure to suck in outdoor air through the air inlet pipe 230. When the fan 220 is running, the air sucked in from the air inlet pipe 230 flows in the volute 210 and is output from the second air outlets 240 on both sides.

[0049] Through the design and layout of the above structure, the introduction and two-way delivery functions of outdoor air can be realized. The outdoor air first enters the volute 210 through the air inlet pipe 230, and then is output from the second air outlets 240 on both sides and enters the fresh air channel 300 under the action of the fan 220. This structural layout is reasonable and compact, and the functional components are smoothly connected, ensuring that the fresh air module 200 can operate effectively after being horizontally installed in the second cavity 120.

[0050] In one embodiment, if Figure 4 As shown, the volute 210 includes: a volute body 211 and a volute cover 212 arranged above the volute body 211; a through hole 213 is arranged on the top surface of the volute cover 212, and a filter assembly is arranged on the through hole 213.

[0051] In this embodiment, the volute body 211 and the volute cover 212 are assembled to form a chamber structure for fresh air circulation, which is used to guide the flow direction of the fresh air. The chamber structure here is the interior of the volute 210. The through hole 213 on the top surface of the volute cover 212 is connected to the above chamber structure. A filter assembly is installed at the through hole 213, which can filter the outdoor air entering from the through hole 213 and remove pollutants in the air.

[0052] Through the above structural design, outdoor air can be purified under the action of the filter assembly, and enter the volute 210 through the through hole 213 on the top surface of the volute cover 212, and then output from the second air outlet 240 on the volute 210 under the action of the fan 220. This structure allows the intake, filtration and delivery of fresh air to form a continuous airflow channel.

[0053] In this embodiment, if Figure 4 As shown, the through hole 213 and the filter assembly are installed between the air inlet pipe 230 and the volute cover 212. This structural design allows the air inlet, filter and conveying parts of the fresh air module 200 to form a compact whole.

[0054] In a specific embodiment, if Figure 4As shown, the edge of the volute 210 cover and the edge of the volute 210 body are both provided with two half-slots 214 in the horizontal direction, and the half-slots 214 on the edge of the volute 210 cover and the half-slots 214 on the edge of the volute 210 body are adjacent to each other up and down to form a second air outlet 240. In this way, a second air outlet 240 is formed on each side of the volute 210.

[0055] In a specific embodiment, if Figure 4 As shown, the filter assembly includes a grille 271 and a filter 272, wherein the grille 271 is mounted on the through hole 213 of the volute 210 cover, and the filter 272 is arranged on the top of the grille 271. The grille 271 can both support the filter 272 and ensure the smooth flow of air. The filter 272 is used to filter the incoming outdoor air and remove pollutants such as dust and pollen in the air. This structural design not only ensures the filtering effect, but also facilitates the cleaning or replacement of the filter 272.

[0056] In one embodiment, if Figure 4 As shown, the fan 220 includes: a driving motor 221 and a centrifugal fan blade 222 connected to the output shaft of the driving motor 221 ; a fixing bracket 250 is arranged between the driving motor 221 and the volute 210 .

[0057] In this embodiment, the fixing bracket 250 is firmly installed inside the volute 210, and the driving motor 221 is fixed at a predetermined position by the fixing bracket 250. The centrifugal fan blade 222 rotates at a high speed driven by the driving motor 221, sucking in the fresh air passing through the filter 272 from the axial direction and then discharging it from the radial direction, thereby realizing the directional delivery of the fresh air. The setting of the fixing bracket 250 enables the centrifugal fan blade 222 and the driving motor 221 to operate stably, avoiding large vibration and noise during operation. Through the coordinated cooperation of the above structures, the stable and efficient delivery of fresh air can be realized.

[0058] In one embodiment, if Figure 4 and Figure 5 As shown, the air supply structure also includes: a first wiring port 260 arranged on the volute 210 and a second wiring port 170 arranged on the chassis 100; wherein, when the fresh air module 200 is installed in the second cavity 120, the first wiring port 260 is electrically connected to the second wiring port 170.

[0059] In this embodiment, when the fresh air module 200 is pushed into and installed in the second cavity 120, the first wiring port 260 on the volute 210 and the second wiring port 170 on the chassis 100 are automatically connected. Metal sheets are arranged inside the two wiring ports. When the two wiring ports are in contact with each other, the contact of the metal sheets inside them is used to complete the conduction, thereby supplying power to the fan 220 and driving it to operate normally.

[0060] Compared to the traditional power-on method of connecting the wires to the mainboard (not shown in the drawings), the plug-in power-on structure adopted in this embodiment facilitates the power supply connection of the fan 220. The traditional method requires manual connection or disconnection of the wires when installing or removing the fresh air module 200, which is inconvenient to operate and easy to damage the wiring. However, the design of this embodiment only requires the fresh air module 200 to be pushed horizontally into the second cavity 120, and the two wiring ports can automatically complete the circuit connection, so that the fan 220 obtains the driving power supply. When the fresh air module 200 needs to be removed, it only needs to be pulled out, and the two wiring ports will be automatically disconnected, avoiding the risk of wire damage that may be caused by the traditional wiring method.

[0061] In a specific embodiment, the power line of the fan 220 is electrically connected to the metal sheet in the first wiring port 260. The metal sheet in the second wiring port 170 is connected to the control circuit board (not shown in the drawings) of the air conditioner 400 through a wire. When the fresh air module 200 is pushed into the second cavity 120, the metal sheet of the first wiring port 260 is in close contact with the metal sheet corresponding to the second wiring port 170, thereby forming a power supply circuit.

[0062] In one embodiment, if Figure 7 As shown, the fresh air channel 300 includes a relatively distributed first fresh air channel 310 and a second fresh air channel 320; second air outlets 240 are respectively arranged on the opposite sides of the fresh air module 200, the inlet of the first fresh air channel 310 is connected to the second air outlet 240 on one side, and the inlet of the second fresh air channel 320 is connected to the second air outlet 240 on the other side; the outlets of the first fresh air channel 310 and the second fresh air channel 320 are both connected to the first air outlet 130.

[0063] In this embodiment, the fresh air module 200 is provided with a second air outlet 240 on the left and right sides thereof, respectively. Correspondingly, a first fresh air passage 310 and a second fresh air passage 320 are provided inside the chassis 100 and are distributed on the left and right sides. Specifically, the inlet of the first fresh air passage 310 is communicated with the second air outlet 240 on the left side of the fresh air module 200, and the inlet of the second fresh air passage 320 is communicated with the second air outlet 240 on the right side of the fresh air module 200. The outlets of the first fresh air passage 310 and the second fresh air passage 320 both extend to the first cavity 110 (front area) of the chassis 100 and are communicated with the first air outlet 130.

[0064] In actual operation, after passing through the fresh air module 200, the outdoor air is output from the second air outlets 240 on the left and right sides respectively, and is transported to the first air outlet 130 through the first fresh air channel 310 and the second fresh air channel 320 respectively. Since the outlets of the first fresh air channel 310 and the second fresh air channel 320 are both connected to the first air outlet 130, the fresh air and the air supply of the main air duct 600 are mixed and supplied at the first air outlet 130. At the same time, with the driving effect of the air supply airflow of the main air duct 600, the air supply distance of the fresh air can be increased.

[0065] In a specific embodiment, the design of the dual air ducts (the first fresh air duct 310 and the second fresh air duct 320) enables the air conditioner 400 to achieve three different air supply modes during operation:

[0066] When the fresh air dual-duct air supply mode is activated, fresh air is simultaneously delivered from the second air outlets 240 on the left and right sides of the fresh air module 200, and delivered to the first air outlet 130 through the first fresh air channel 310 and the second fresh air channel 320 respectively, and then merged with the airflow of the main air duct 600 to form mixed air and delivered to the room. Since the fresh air is delivered from two channels in a dispersed manner, the fresh air volume is increased, and the fresh air and the airflow of the main air duct 600 are mixed more evenly, thereby improving the air supply effect.

[0067] When the single-side air supply is activated, fresh air is only delivered from the second air outlet 240 on one side and is transported through the corresponding (first or second) fresh air passage 300. For example, when only the left side air supply is activated, fresh air is only delivered from the second air outlet 240 on the left side and is transported through the first fresh air passage 310; when only the right side air supply is activated, fresh air is only delivered from the second air outlet 240 on the right side and is transported through the second fresh air passage 320. This single-side air supply mode can be flexibly switched according to actual needs.

[0068] The dual air duct structure design not only improves the flexibility of fresh air supply, but also makes fresh air delivery smoother by setting two independent fresh air channels 300, avoiding the limitations of single-channel delivery. At the same time, since the outlets of the two fresh air channels 300 are connected to the first air outlet 130, the fresh air is more fully mixed with the airflow of the main air duct 600, which can effectively reduce the uneven temperature distribution.

[0069] In one embodiment, if Figure 7 As shown, the first cavity 110 and the second cavity 120 are distributed front and back, the first fresh air channel 310 is arranged in the left area between the first cavity 110 and the second cavity 120, and the second fresh air channel 320 is arranged in the right area between the first cavity 110 and the second cavity 120; the cross-sections of the first fresh air channel 310 and the second fresh air channel 320 along the horizontal direction are both arc-shaped.

[0070] In this embodiment, the first cavity 110 and the second cavity 120 are distributed front and back in the chassis 100. The first fresh air passage 310 is arranged in the left area between the first cavity 110 and the second cavity 120, starting from the second air outlet 240 on the left side of the fresh air module 200, extending forward along the left edge of the chassis 100, and finally leading to the first air outlet 130. Correspondingly, the second fresh air passage 320 is arranged in the right area between the first cavity 110 and the second cavity 120, starting from the second air outlet 240 on the right side of the fresh air module 200, extending forward along the right edge of the chassis 100, and finally leading to the first air outlet 130. Here, the left area and the right area are the left area and the right area in the chassis 100, respectively.

[0071] The shape design of the first fresh air channel 310 and the second fresh air channel 320 both adopts an arc-shaped structure. This arc-shaped channel structure is based on the Coanda effect principle in fluid mechanics. When the fresh air flows along the arc-shaped channel, the airflow will naturally stick to the arc wall and move. For example, when the fresh air flows out from the first fresh air channel 310 on the left, the airflow will deflect along the arc-shaped channel toward the direction of the first air outlet 130; when it flows out from the second fresh air channel 320 on the right, the airflow will deflect along the arc-shaped channel toward the direction of the first air outlet 130.

[0072] This arc-shaped channel design is not only conducive to the guidance of airflow, but also can reduce the resistance loss of airflow in the channel and improve the air supply efficiency. At the same time, since both the left and right fresh air channels 300 adopt an arc-shaped structure, the fresh air can form a better mixing effect when it merges with the airflow of the main air duct 600.

[0073] In one embodiment, if Figure 3 As shown, the air supply structure also includes: a first baffle 330 arranged at the entrance of the first fresh air channel 310 and a second baffle 340 arranged at the entrance of the second fresh air channel 320; wherein the first baffle 330 and the second baffle 340 are configured to be independently adjustable.

[0074] In this embodiment, a first baffle 330 is provided at the entrance of the first fresh air passage 310, and a second baffle 340 is provided at the entrance of the second fresh air passage 320. The first baffle 330 and the second baffle 340 can independently control the opening or closing state of each channel. Here, the actual function of the first baffle 330 and the second baffle 340 is to block the second air outlet 240 on one side of the fresh air module 200.

[0075] Specifically, by controlling the opening and closing combination of the two baffles, different air supply modes can be achieved: when the first baffle 330 and the second baffle 340 are opened at the same time, fresh air can be delivered through two channels at the same time; when the first baffle 330 is opened and the second baffle 340 is closed, fresh air is only delivered from the left channel; when the first baffle 330 is closed and the second baffle 340 is opened, fresh air is only delivered from the right channel.

[0076] The design of the baffle structure makes the fresh air supply mode more flexible and changeable. By adjusting the opening and closing combination of the first baffle 330 and the second baffle 340, a suitable air supply mode can be selected according to actual use requirements.

[0077] In a specific embodiment, the first baffle 330 and the second baffle 340 are both fan-shaped plate structures, and a rotating shaft (not shown in the drawings) is provided at the edge of each baffle. The rotating shaft is rotatably connected to a bearing seat provided on the volute 210 (not shown in the drawings), so that the baffle can rotate around the rotating shaft. The rotation angle range of the baffle is 0° to 90°, where 0° corresponds to a fully closed state of the channel, and 90° corresponds to a fully open state of the channel.

[0078] A driving device (not shown in the drawings) is connected to the extended end of the rotating shaft of each baffle, specifically a stepper motor. The stepper motor is fixedly connected to the rotating shaft of the baffle through its output shaft, and is used to drive the baffle to achieve angle adjustment. The two baffles are driven by independent stepper motors, so that they can be controlled independently.

[0079] like Figure 8 As shown, corresponding to the above air supply structure, an embodiment of the present invention further provides an air conditioner 400, which is specifically a vertical air conditioner. The air conditioner 400 includes: a housing 500 and a main air duct 600 disposed in the housing 500; the housing 500 is provided with an air supply structure of any of the above embodiments, and the first air outlet 130 of the air supply structure is connected to the main air duct 600.

[0080] In this embodiment, the housing 500 is the outer shell of the air conditioner 400, which plays a role of protection and decoration. In the housing 500, the air supply structure is installed at the bottom position. A main air duct 600 is arranged above the chassis 100, and the inside of the main air duct 600 is used to transport the airflow processed by the air conditioner 400. The outlet of the main air duct 600 is connected to the first air outlet 130 of the first cavity 110 (front area) of the chassis 100. This connection method forms a complete air supply passage: the airflow processed by the air conditioner 400 is transported downward from the main air duct 600 and sent into the room through the first air outlet 130.

[0081] Since the outlet of the main air duct 600 is connected to the first air outlet 130, when the fresh air is delivered to the first air outlet 130 through the fresh air channel 300, it can be fully mixed with the airflow delivered by the main air duct 600. This airflow merging method can better integrate the processed air-conditioned airflow with the fresh air, which is beneficial to improving the indoor air quality and enhancing the user experience.

[0082] In summary, the air supply structure and air conditioner 400 provided in this embodiment firstly divide the chassis 100 into the first cavity 110 and the second cavity 120, and adopt the method of horizontal installation of the fresh air module 200, so as to realize the reasonable zoning utilization of the space. The fresh air module 200 occupies the horizontal space of the second cavity 120, avoids competing with the main air duct 600 for space in the vertical direction, reserves sufficient vertical expansion space for the main air duct design and components such as the evaporator, and overcomes the problem of the fresh air system occupying a large amount of vertical space in the prior art.

[0083] At the same time, the fresh air channel 300 connects the second air outlet 240 with the first air outlet 130, so that the fresh air can merge with the air supply of the main air duct 600 at the first air outlet 130. This design allows the two airflows to be fully mixed before the air is discharged, effectively reducing the uneven temperature distribution, and solving the problem of users feeling hot and cold due to the separate discharge of fresh air and the main air duct in the prior art. At the same time, the fresh air can also increase the air supply distance with the help of the driving effect of the airflow of the main air duct 600, overcoming the problem of limited air supply distance caused by the position of the fresh air outlet in the traditional layout.

[0084] In addition, the overall structural design of the chassis 100 cooperates with the horizontal installation method of the fresh air module 200, which not only ensures the compactness of the structure and the reliability of installation, but also facilitates daily maintenance. This design not only meets the functional requirements, but also improves the integration of the whole machine.

[0085] It can be seen that this embodiment not only solves the technical problems in the prior art such as the large space occupied by the fresh air system, uneven air supply temperature and limited air supply distance, but also achieves efficient utilization of the entire machine space and significant improvement in the air supply effect, thereby enhancing the user experience.

[0086] The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can easily think of various equivalent modifications or replacements within the technical scope disclosed by the present invention, and these modifications or replacements should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention shall be based on the protection scope of the claims.
