Description

Technical Field

[0001] This invention relates to the field of air conditioning technology, and more particularly to an air supply structure and an air conditioner. Background Technology

[0002] The application of fresh air systems in air conditioners is now widespread. Fresh air systems not only improve indoor air quality but also enhance the comfort and safety of living and working environments.

[0003] Currently, floor-standing air conditioners (cabinet units) on the market use a top-to-bottom air distribution design. In this design, the fresh air system is usually installed behind the base, and the lower air outlet duct is arranged in a front-to-back direction with the fresh air system; at the same time, the fresh air outlet is located at the side and rear of the entire unit. This design results in low utilization of the internal space of the unit. Because the fresh air system occupies a large space, the lower air outlet duct needs to give up some space, which limits the size and shape design of the duct. If the evaporator length is increased to increase the overall air intake, the existing space layout will not meet the requirements. At the same time, when there is a large temperature difference between the fresh air and the main air supply air, it will cause users to experience discomfort from sudden temperature changes. Summary of the Invention

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

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

[0033] It should also be further understood that the term "and / or" as used in this specification and the appended claims refers to any combination of one or more of the associated listed items and all possible combinations, and includes such combinations.

[0034] Please also refer to Figures 1-7 The air supply structure provided in this embodiment of the invention is applicable to an air conditioner 400, which includes a main air duct 600. The air supply structure includes: a chassis 100, which has a first cavity 110 and a second cavity 120. A first air outlet 130 is provided on the first cavity 110 and is connected to the main air duct 600; a fresh air module 200, which is horizontally installed in the second cavity 120 and has a second air outlet 240; and a fresh air duct 300, which is disposed within the chassis 100. One end of the fresh air duct 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 mixes with the air supplied by the main air duct 600 at the first air outlet 130.

[0035] In this embodiment, as Figure 1As shown, the chassis 100 serves as the basic load-bearing component, 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. This first air outlet 130 is connected to the main air duct 600 of the air conditioner 400, enabling the air conditioner 400 to supply air to the room. Specifically, the top wall of the first cavity 110 is vertically continuous, and this continuous section connects to the main air duct 600, thereby connecting the main air duct 600 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 within the second cavity 120 of the chassis 100. This horizontal installation layout design makes the space occupied by the fresh air module 200 within the air conditioner 400 more reasonable, leaving ample installation space for other components. The fresh air module 200 is equipped with a second air outlet 240 for delivering outdoor air (fresh air) to the room.

[0037] A fresh air duct 300 is provided within the chassis 100. One end of the fresh air duct 300 is connected to the second air outlet 240 of the fresh air module 200, and the other end extends to the first cavity 110 and connects to the first air outlet 130. This duct connection design allows the fresh air to merge with the air supplied by the main air duct 600 at the first air outlet 130, forming a mixed airflow that is then jointly delivered into the room. This air supply structure design allows the fresh air to mix with the airflow from the main air duct 600 at the first air outlet 130, reducing the temperature difference between the two airflows and preventing users from experiencing sudden temperature changes. It also utilizes the airflow from the main air duct 600 to increase the delivery distance of the fresh air.

[0038] This air supply structure effectively solves the technical problems in the prior art, such as the large space occupied by the fresh air system, the large temperature difference between the fresh air and the main air duct 600 leading to poor user experience, and the limited fresh air supply distance, by rationally arranging the installation position of the fresh air module 200 and the direction of the fresh air duct 300.

[0039] In this embodiment, "horizontal installation" means that the fresh air module 200 is installed in the second cavity 120 with its axial direction (i.e., the axis of the drive motor 221) basically perpendicular to the ground, allowing the centrifugal fan blades 222 to rotate in the horizontal plane. This installation method allows for a certain tilt angle, rather than strictly requiring complete perpendicularity to the ground. This also achieves more compact space utilization and more convenient installation and maintenance.

[0040] In one 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 the central part of the cover is designed with an air guide plate structure (not shown in the figure) to guide the air outlet 130.

[0041] In one embodiment, such as Figure 1 As shown, the first cavity 110 and the second cavity 120 are distributed opposite to each other. The second cavity 120 is provided with an installation channel 150, which 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 to back within the chassis 100. The second cavity 120 is provided with an installation channel 150, which allows the fresh air module 200 to be horizontally inserted and installed within it. This design facilitates the installation, disassembly, and maintenance of the fresh air module 200 while ensuring installation stability. Through the installation channel 150, the fresh air module 200 can be smoothly pushed into or pulled out of the second cavity 120, enabling quick and convenient installation.

[0043] In one specific embodiment, such as Figure 6 As shown, the installation channel 150 includes a first mounting hole 151 located on the top wall of the second cavity 120 and a second mounting hole 152 located on the rear wall of the second cavity 120. The first mounting hole 151 is located directly above the fresh air module 200 and is used to accommodate the air inlet duct 230. The width of the second mounting hole 152 is greater than the width of the volute 210, and the height is greater than the height of the volute 210, allowing the fresh air module 200 (volute 210) to be horizontally pushed in from the rear of the chassis 100 for installation. This dual-hole design allows the fresh air module 200 to be installed securely while facilitating installation and maintenance.

[0044] In this embodiment, the second cavity 120 corresponds to the rear region of the chassis 100. A rear cover 162 is installed at the second mounting hole 152 in the rear region for fixing the fresh air module 200 inside 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 closer to the user is the front area, and the area farther 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, such as Figure 2 and Figure 6 As shown, the fresh air module 200 includes: a volute 210, a fan 220 disposed inside the volute 210, and an air inlet pipe 230 communicating with the inside of the volute 210; a second air outlet 240 is provided on each of the opposite sides of the volute 210.

[0047] In this embodiment, the volute 210 serves as a channel for forming a fresh airflow, and second air outlets 240 are respectively provided on its opposite sides. This dual-sided air outlet design allows fresh air to be delivered in two directions simultaneously, which is beneficial for the distribution and diffusion of fresh air.

[0048] An air inlet duct 230 is installed above the volute 210 and communicates with the interior of the volute 210 to create an air intake channel for outdoor air (fresh air). A fan 220 is installed inside the volute 210. The rotation of the fan 220 generates negative pressure, drawing outdoor air in through the air inlet duct 230. When the fan 220 is running, the air drawn in from the air inlet duct 230 flows within the volute 210 and is output from the second air outlets 240 on both sides.

[0049] The design and layout of the above structure enable the introduction and bidirectional delivery of outdoor air. Outdoor air first enters the volute 210 through the air inlet duct 230, and then, under the action of the fan 220, is output from the second air outlets 240 on both sides and enters the fresh air duct 300. This structural layout is reasonable and compact, with smooth connections between various functional components, ensuring that the fresh air module 200 can operate effectively after being horizontally installed in the second cavity 120.

[0050] In one embodiment, such as Figure 4 As shown, the volute 210 includes: a volute body 211 and a volute cover 212 disposed above the volute body 211; the top surface of the volute cover 212 is provided with a through hole 213, and a filter assembly is disposed 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 guides the flow direction of fresh air. This chamber structure is the interior of the volute 210. The through hole 213 on the top surface of the volute cover 212 communicates with the aforementioned chamber structure. A filter assembly is installed at the through hole 213, which can filter the outdoor air entering through the through hole 213 and remove pollutants from the air.

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

[0053] In this embodiment, as 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 makes the air inlet, filtration and delivery parts of the fresh air module 200 form a compact whole.

[0054] In one specific embodiment, such as Figure 4As shown, both the edge of the volute 210 cover and the edge of the volute 210 body have two semi-open slots 214 in the horizontal direction. When the semi-open slots 214 on the edge of the volute 210 cover and the semi-open slots 214 on the edge of the volute 210 body are adjacent to each other, a second air outlet 240 is formed. In this way, a second air outlet 240 is formed on each side of the volute 210.

[0055] In one specific embodiment, such as Figure 4 As shown, the filter assembly includes a grille 271 and a filter screen 272. The grille 271 is mounted on the through hole 213 of the volute 210 cover, and the filter screen 272 is positioned on top of the grille 271. The grille 271 supports the filter screen 272 while ensuring smooth airflow. The filter screen 272 filters incoming outdoor air, removing pollutants such as dust and pollen. This structural design ensures effective filtration while facilitating cleaning or replacement of the filter screen 272.

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

[0057] In this embodiment, the fixed bracket 250 is securely installed inside the volute 210, and the drive motor 221 is fixed in a predetermined position by the fixed bracket 250. The centrifugal fan 222 rotates at high speed under the drive of the drive motor 221, drawing in fresh air passing through the filter 272 axially and then discharging it radially, thus achieving directional delivery of fresh air. The fixed bracket 250 ensures stable operation of the centrifugal fan 222 and the drive motor 221, avoiding significant vibration and noise during operation. Through the coordinated operation of the above structures, stable and efficient delivery of fresh air can be achieved.

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

[0059] In this embodiment, when the fresh air module 200 is pushed into and installed into 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. Both wiring ports have internal metal plates. When the two wiring ports come into contact, the contact of the internal metal plates completes the electrical conductivity, thereby supplying power to the fan 220 and driving its normal operation.

[0060] Compared to the traditional power supply method of connecting wires to the motherboard (not shown in the attached diagram), the plug-in power supply structure adopted in this embodiment facilitates the power supply connection of the fan 220. The traditional method requires manually connecting or disconnecting wires when installing or removing the fresh air module 200, which is inconvenient and prone to damaging the wiring. In this embodiment, however, simply pushing the fresh air module 200 horizontally into the second cavity 120 automatically completes the circuit connection at the two wiring ports, providing power to the fan 220. When it is necessary to remove the fresh air module 200, simply pulling it out automatically disconnects the two wiring ports, avoiding the risk of wire damage that may occur with traditional wiring methods.

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

[0062] In one embodiment, such as Figure 7 As shown, the fresh air duct 300 includes a first fresh air duct 310 and a second fresh air duct 320 that are relatively distributed; the fresh air module 200 is provided with a second air outlet 240 on each of its opposite sides; the inlet of the first fresh air duct 310 is connected to the second air outlet 240 on one side, and the inlet of the second fresh air duct 320 is connected to the second air outlet 240 on the other side; the outlets of the first fresh air duct 310 and the second fresh air duct 320 are both connected to the first air outlet 130.

[0063] In this embodiment, the fresh air module 200 has second air outlets 240 on its left and right sides, respectively. Correspondingly, a first fresh air channel 310 and a second fresh air channel 320 are arranged side-by-side inside the chassis 100. Specifically, the inlet of the first fresh air channel 310 is connected to the second air outlet 240 on the left side of the fresh air module 200, and the inlet of the second fresh air channel 320 is connected to the second air outlet 240 on the right side of the fresh air module 200. The outlets of both the first fresh air channel 310 and the second fresh air channel 320 extend to the first cavity 110 (front area) of the chassis 100 and are connected to the first air outlet 130.

[0064] In actual operation, outdoor air, after passing through the fresh air module 200, is output from the second air outlets 240 on the left and right sides respectively, and is correspondingly delivered to the first air outlet 130 through the first fresh air duct 310 and the second fresh air duct 320. Since the outlets of both the first fresh air duct 310 and the second fresh air duct 320 are connected to the first air outlet 130, the fresh air and the air supplied by 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 airflow supplied by the main air duct 600, the delivery distance of the fresh air can be increased.

[0065] In one specific embodiment, this dual-airflow design (first fresh air duct 310 and second fresh air duct 320) allows the air conditioner 400 to achieve three different air supply modes during operation:

[0066] When the dual-duct fresh 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. It is then transported to the first air outlet 130 via the first fresh air channel 310 and the second fresh air channel 320, respectively, where it merges with the airflow from the main air duct 600 to form a mixed airflow that is then delivered into the room. Because the fresh air is delivered dispersedly through two channels, the fresh air volume is increased, and the fresh air mixes more evenly with the airflow in the main air duct 600, thereby improving the air supply effect.

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

[0068] This dual-duct structure design not only improves the flexibility of fresh air supply, but also makes the 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 both fresh air channels 300 are connected to the first air outlet 130, the fresh air mixes more thoroughly with the airflow in the main air duct 600, which can effectively reduce uneven temperature distribution.

[0069] In one embodiment, such as Figure 7 As shown, the first cavity 110 and the second cavity 120 are distributed front to back. The first fresh air duct 310 is located in the left area between the first cavity 110 and the second cavity 120, and the second fresh air duct 320 is located in the right area between the first cavity 110 and the second cavity 120. The cross-sections of the first fresh air duct 310 and the second fresh air duct 320 in the horizontal direction are both arc-shaped.

[0070] In this embodiment, the first cavity 110 and the second cavity 120 are distributed front to back within the chassis 100. The first fresh air duct 310 is located in the left-side region 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 duct 320 is located in the right-side region 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 also finally leading to the first air outlet 130. Here, the left-side region and the right-side region refer to the left and right sides of the chassis 100, respectively.

[0071] Both the first fresh air duct 310 and the second fresh air duct 320 are designed with an arc-shaped structure. This arc-shaped duct structure is based on the Coanda effect principle in fluid mechanics. When fresh air flows along the arc-shaped duct, the airflow will naturally adhere to the arc-shaped wall surface. For example, when fresh air flows out from the first fresh air duct 310 on the left, the airflow will deflect along the arc-shaped duct towards the direction of the first air outlet 130; when it flows out from the second fresh air duct 320 on the right, the airflow will deflect along the arc-shaped duct towards the direction of the first air outlet 130.

[0072] This arc-shaped channel design not only facilitates airflow guidance but also reduces airflow resistance loss within the channel, improving air delivery efficiency. Furthermore, because both the left and right fresh air channels 300 employ an arc-shaped structure, the fresh air achieves a better mixing effect when it converges with the airflow from the main air duct 600.

[0073] In one embodiment, such as Figure 3 As shown, the air supply structure also includes: a first baffle 330 disposed at the inlet of the first fresh air duct 310 and a second baffle 340 disposed at the inlet of the second fresh air duct 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 inlet of the first fresh air duct 310, and a second baffle 340 is provided at the inlet of the second fresh air duct 320. The first baffle 330 and the second baffle 340 can independently control the opening or closing state of their respective ducts. 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 both channels at the same time; when the first baffle 330 is open and the second baffle 340 is closed, fresh air is delivered only from the left channel; when the first baffle 330 is closed and the second baffle 340 is open, fresh air is delivered only from the right channel.

[0076] The design of this baffle structure makes the fresh air delivery method more flexible and versatile. By adjusting the opening and closing combination of the first baffle 330 and the second baffle 340, a suitable air delivery mode can be selected according to actual usage needs.

[0077] In one specific embodiment, both the first baffle 330 and the second baffle 340 adopt a fan-shaped plate structure, and each baffle has a rotating shaft (not shown in the figure) on its edge. The rotating shaft is rotatably connected to a bearing seat (not shown in the figure) provided on the volute 210, allowing the baffle to rotate around the rotating shaft. The rotation angle range of the baffle is 0° to 90°, where 0° corresponds to the channel being completely closed and 90° corresponds to the channel being completely open.

[0078] A drive device (not shown in the attached diagram), specifically a stepper motor, is connected to the extended end of the rotating shaft of each baffle. The stepper motor is fixedly connected to the rotating shaft of the baffle via its output shaft, and is used to drive the baffle to achieve angle adjustment. The two baffles are each driven by an independent stepper motor, thus achieving independent control.

[0079] like Figure 8 As shown, corresponding to the above air supply structure, this embodiment of the invention also 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 within the housing 500; the housing 500 is provided with an air supply structure of any of the aforementioned 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 serves as the outer shell of the air conditioner 400, providing both protection and decoration. Inside the housing 500, the air supply structure is installed at the bottom. A main air duct 600 is located above the chassis 100, and 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 path: the airflow processed by the air conditioner 400 is transported downwards from the main air duct 600 and delivered 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 fresh air is delivered to the first air outlet 130 through the fresh air duct 300, it can be fully mixed with the airflow delivered from the main air duct 600. This airflow convergence method allows the treated air conditioning airflow to blend better with the fresh air, which is beneficial for improving 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 a first cavity 110 and a second cavity 120, and then adopts a horizontal installation method for the fresh air module 200, thus achieving reasonable zoning and utilization of space. The fresh air module 200 occupies the horizontal space of the second cavity 120, avoiding competition with the main air duct 600 for vertical space, and reserving sufficient vertical expansion space for the main air duct design and evaporator and other components, overcoming the problem of existing fresh air systems occupying a large amount of vertical space.

[0083] Meanwhile, the fresh air duct 300 connects the second air outlet 240 with the first air outlet 130, allowing the fresh air to converge with the air supplied by the main air duct 600 at the first air outlet 130. This design ensures thorough mixing of the two airflows before they exit, effectively reducing uneven temperature distribution and solving the problem of fluctuating temperatures experienced by users due to separate fresh air and main air duct outlets in existing technologies. Furthermore, the fresh air can utilize the airflow from the main air duct 600 to extend its delivery distance, overcoming the limitation on delivery distance caused by the location of the fresh air outlet in traditional layouts.

[0084] Furthermore, the overall structural design of the chassis 100, in conjunction with the horizontal installation method of the fresh air module 200, ensures both structural compactness and installation reliability, while also facilitating daily maintenance. This design, while meeting functional requirements, also improves the overall integration of the unit.

[0085] As can be seen, this embodiment not only solves the technical problems of large space occupation, uneven air supply temperature and limited air supply distance in the prior art, but also achieves efficient use of the whole unit space and significant improvement in air supply effect, thereby enhancing the user experience.

[0086] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in the present invention, and these modifications or substitutions should all be covered within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
