[0002] With users' continuous pursuit of healthy living, the concept of fresh air air conditioners is becoming increasingly accepted by the public. Fresh air air conditioners bring in fresh air from the outside, achieving the goal of keeping indoor air fresher even without opening windows. As the concept of fresh air has become popular, the concept of exhaust air has also emerged. People hope to accelerate the exchange of air between indoor and outdoor by exhausting air from indoors to outdoors. In related technologies, the exhaust module and the fresh air module are independent of each other, resulting in a larger overall air conditioner size. This does not meet the needs of most users who prefer smaller air conditioners, making the product lose its competitive appearance.

[0003] In addition, because the principle of the fresh air module is to draw air from the outside to the inside, and the principle of the exhaust module is to exhaust air from the inside to the outside, if the two are forced to share the same air duct, due to their different mechanisms, the air duct volute curve under certain suction or exhaust conditions will not match the actual work situation, which will seriously reduce the module efficiency and lose its practical application value.

[0039] The following combination Figures 1-11 A ventilation module 10 for an air conditioner and an air conditioner having the ventilation module 10 according to an embodiment of the present invention will be described in detail.

[0040] Reference Figures 1-10 As shown, the air exchange module 10 for air conditioning according to an embodiment of the present invention has a fresh air mode and an exhaust mode. When the air exchange module 10 is applied to the air conditioner and the air conditioner is used to adjust the indoor temperature, the fresh air mode can transport fresh air from the outdoors to the indoors, and the exhaust mode can discharge the indoor air to the outdoors. The fresh air mode and the exhaust mode are used alternately to realize the air flow exchange between indoor and outdoor, so as to achieve the purpose of making the indoor gas fresher without opening the windows.

[0041] Specifically, the air exchange module 10 may include a volute body and an exhaust guide 5 .

[0042] Among them, reference Figure 7-10 As shown, a first chamber 11 and a second chamber 21 are formed in the volute body, and the first chamber 11 and the second chamber 21 are connected through an air guide ring 31. In a specific example, the first chamber 11 and the second chamber 21 can be separated by a partition plate 3, and the air guide ring 31 is opened on the partition plate 3. The gas in the first chamber 11 (taking air as an example) and the gas in the second chamber 21 can be connected through the air guide ring 31. For example, the air in the first chamber 11 can enter the second chamber 21 through the air guide ring 31, and the air in the second chamber 21 can also enter the first chamber 11 through the air guide ring 31.

[0043] A common air vent 42 is provided on the cavity wall of the first cavity 11 and / or the second cavity 21. Specifically, in some embodiments, the common air vent 42 may be provided only on the cavity wall of the first cavity 11. Figure 1 、 Figure 3 、 Figure 5 、 Figure 7-Figure 8 In other embodiments, the common vent 42 may be opened only on the wall of the second chamber 21; in other embodiments, the common vent 42 may be opened on the walls of the first chamber 11 and the second chamber 21 at the same time, as shown. Figure 9-10 shown.

[0044] Reference Figure 1 、 Figure 3 、 Figure 5 As shown, an exhaust air inlet 12 that can be opened or closed is provided on the wall of the first chamber 11. When the exhaust air inlet 12 is opened, the exhaust air inlet 12 connects the external space of the volute body with the first chamber 11; when the exhaust air inlet 12 is closed, the first chamber 11 cannot be connected with the external space of the volute body through the exhaust air inlet 12.

[0045] Reference Figure 2 、 Figure 4 、 Figure 6As shown, a fresh air outlet 22 that can be opened or closed is provided on the cavity wall of the second chamber 21. When the fresh air outlet 22 is opened, the fresh air outlet 22 connects the external space of the volute body with the second chamber 21; when the fresh air outlet 22 is closed, the second chamber 21 cannot be connected with the external space of the volute body through the fresh air outlet 22.

[0046] The exhaust guide 5 is arranged in the volute body, and the position of the exhaust guide 5 in the volute body can be adjusted. The exhaust guide 5 has a fresh air position and an exhaust position. By adjusting the position of the exhaust guide 5, the exhaust guide 5 can be placed in the fresh air position or the exhaust position. When the exhaust guide 5 is in the fresh air position, the exhaust guide 5 is used to separate the second chamber 21 from the common air outlet 42 and connect the first chamber 11 with the common air outlet 42, so that the fresh air coming in from the common air outlet 42 can enter the first chamber 11, but cannot directly enter the second chamber 21, and then enter the second chamber 21 from the first chamber 11 through the air guide ring 31. When the exhaust guide 5 is in the exhaust position, the exhaust guide 5 is used to separate the first chamber 11 from the common air outlet 42 and connect the second chamber 21 with the common air outlet 42, so that the air in the second chamber 21 can be discharged through the common air outlet 42, and the air at the common air outlet 42 cannot directly enter the first chamber 11.

[0047] When the air exchange module 10 is in the fresh air mode, the exhaust air inlet 12 is closed, the fresh air outlet 22 is opened, the exhaust guide 5 is in the fresh air position, the second chamber 21 is not connected with the common air outlet 42, and the first chamber 11 is connected with the common air outlet 42. In this way, the fresh air coming in from the common air outlet 42 can enter the first chamber 11. Since the exhaust air inlet 12 is closed, the air in the first chamber 11 enters the second chamber 21 through the air guide ring 31. Since the fresh air outlet 22 is open, the air in the second chamber 21 goes out from the fresh air outlet 22. When the common air outlet 42 is connected with the outdoors and the fresh air outlet 22 is connected with the indoors, the air in the second chamber 21 enters the indoors from the fresh air outlet 22, thereby replenishing fresh air to the indoors.

[0048] When the air exchange module 10 is in exhaust mode, the fresh air outlet 22 is closed, the exhaust air inlet 12 is opened, the exhaust guide 5 is in the exhaust position, the first chamber 11 is not connected to the common air outlet 42, and the second chamber 21 is connected to the common air outlet 42. In this way, the air entering the first chamber 11 from the exhaust air inlet 12 can enter the second chamber 21 through the air guide ring 31, and the air in the second chamber 21 can be discharged through the common air outlet 42. When the exhaust air inlet 12 is connected to the indoor room and the common air outlet 42 is connected to the outdoor room, the indoor air can be discharged to the outdoor room through the air exchange module 10.

[0049] When the air exchange module 10 is applied to the air conditioner, the common air outlet 42 is connected to the outdoors, and the common air outlet 42 can be located on the side of the air exchange module 10 facing the outdoors. The fresh air outlet 22 and the exhaust air inlet 12 are both connected to the indoors, and the fresh air outlet 22 and the exhaust air inlet 12 can both be located on the side of the air exchange module 10 facing the indoors.

[0050] When the air exchange module 10 is in the fresh air mode, the exhaust air inlet 12 is closed and the fresh air outlet 22 is opened. Figure 1-Figure 2 、 Figure 7 、 Figure 9 As shown, the air flow direction inside the air exchange module 10 is the F1 direction: common air outlet 42 → first chamber 11 → air guide ring 31 → second chamber 21 → fresh air outlet 22 .

[0051] When the air exchange module 10 is in exhaust mode, the fresh air outlet 22 is closed and the exhaust air inlet 12 is opened. Figure 3-Figure 6 、 Figure 8 、 Figure 10 As shown, the air flow direction inside the air exchange module 10 is the F2 direction: exhaust air inlet 12 → first chamber 11 → air guide ring 31 → second chamber 21 → common air outlet 42 .

[0052] The fresh air mode and exhaust air mode of the air exchange module 10 share the same air duct structure, which can ensure that the external dimensions of the air exchange module 10 are small. When the air exchange module 10 is applied to an air conditioner, it is also conducive to miniaturization of the air conditioner.

[0053] The "X" at the air guide ring 31 represents that the airflow flows vertically inwards in this view. Figure 1 As shown by the "X" at A, Figure 3 As shown by the "X" at B, Figure 5 The "X" at E in the middle is shown. Figure 2 and Figure 4 The “O” at the air guide ring 31 represents that the airflow flows outward perpendicular to the paper in this view, as shown in FIG. Figure 3 As shown by the "O" at C in the middle, Figure 5 As shown by the "O" at G in the figure.

[0054] It should be noted that when the ventilation module 10 is applied to other devices requiring ventilation, the gas flowing through the ventilation module 10 is not necessarily air, but may also be other gases, such as nitrogen, oxygen, etc., which are not listed here. For ease of description and understanding, the present invention is described as an example in which the gas flowing through the ventilation module 10 is air.

[0055] According to the air exchange module 10 of the embodiment of the present invention, by setting an exhaust guide 5 with adjustable position, the air exchange module 10 can be switched to fresh air mode or exhaust mode, so that the same air exchange module 10 integrates the suction function and the exhaust function, avoiding the problem of increased number and volume of air-conditioning components caused by the independence of the fresh air module and the exhaust module. The present invention is conducive to reducing the number of air-conditioning components, simplifying the air-conditioning structure, and reducing the volume of the air-conditioning.

[0056] In some embodiments of the present invention, reference Figures 1-6 As shown, the exhaust guide 5 may include a switching valve 51 and a volute valve 52. An exhaust port 24 is provided on the cavity wall of the second chamber 21. When the exhaust guide 5 is in the fresh air position, the switching valve 51 separates the second chamber 21 from the common air port 42, and the first chamber 11 is connected to the common air port 42. The volute valve 52 is located on the side of the switching valve 51 close to the second chamber 21, and the volute valve 52 blocks the exhaust port 24 so that the volute valve 52 is constructed as a part of the cavity wall of the second chamber 21. Similarly, when the air in the second chamber 21 hits the volute valve 52, the volute valve 52 can guide this part of the air, and the shape of the volute valve 52 also determines the guiding effect; when the exhaust guide 5 is in the exhaust position, the switching valve 51 separates the first chamber 11 and the common air outlet 42, the volute valve 52 and the exhaust outlet 24 are at least partially offset, the second chamber 21 and the common air outlet 42 are connected through the exhaust outlet 24, and the air in the second chamber 21 can reach the common air outlet 42 through the exhaust outlet 24.

[0057] In some embodiments of the present invention, Figure 5-Figure 6 As shown, the volute valve 52 is fixedly connected to the switching valve 51, and the volute valve 52 and the switching valve 51 are adapted to move synchronously to change positions. For example, in some embodiments, the volute valve 52 and the switching valve 51 can be fixedly connected by welding; in other embodiments, the volute valve 52 and the switching valve 51 can also be fixedly connected using fasteners; in still other embodiments, the volute valve 52 and the switching valve 51 can be integrally formed.

[0058] In some embodiments of the present invention, the volute valve 52 is repositioned by a first driving member. In some embodiments, the first driving member may be a connecting rod, so that the volute valve 52 can be repositioned by rotation. In other embodiments, the first driving member may be a sliding member, so that the volute valve 52 can be repositioned by sliding.

[0059] In some embodiments of the present invention, the switching valve 51 changes position via a second drive member. Alternatively, in some embodiments, the second drive member may be a motor that drives a lead screw to rotate, with the switching valve 51 connected to the lead screw. Thus, when the motor rotates in the forward direction, the lead screw drives the switching valve 51 downward, gradually moving the switching valve 51 to the fresh air position; when the motor rotates in the reverse direction, the lead screw drives the switching valve 51 upward, gradually moving the switching valve 51 to the exhaust air position. In other embodiments, the second drive member may be a linear motor that directly drives the switching valve 51 upward through forward rotation and directly drives the switching valve 51 downward through reverse rotation.

[0060] When the exhaust guide 5 is in the fresh air position, the switching valve 51 can be completely located in the second chamber 21, or most of the area of ​​the switching valve 51 can be located in the second chamber 21; when the exhaust guide 5 is in the exhaust position, the switching valve 51 can be completely located in the first chamber 11, or most of the area of ​​the switching valve 51 can be located in the first chamber 11.

[0061] Optionally, in some embodiments, referring to Figure 2 、 Figure 4 As shown, the volute valve 52 may include a first valve 521 and a second valve 522. When the exhaust guide 5 is in the fresh air position, the ends of the first valve 521 and the second valve 522 facing each other are connected to each other, so that the first valve 521 and the second valve 522 block the exhaust port 24; when the exhaust guide 5 is in the exhaust position, the ends of the first valve 521 and the second valve 522 facing each other are separated, so that the second chamber 21 and the common air port 42 are connected through the exhaust port 24.

[0062] In some embodiments, as Figure 2 、 Figure 4 As shown, the first valve 521 can be driven by the first connecting rod 523 to realize the rotation of the first valve 521 , and the second valve 522 can be driven by the second connecting rod 524 to realize the rotation of the first valve 521 .

[0063] In some embodiments of the present invention, the volute valve 52 is constructed as an arc-shaped plate, and the bending direction of the volute valve 52 is away from the second chamber 21. In this way, the side wall of the second chamber 21 is a continuous, smoothly transitioned curved surface, which can avoid sudden changes in direction when air impacts the volute valve 52.

[0064] Optionally, in other embodiments, the volute valve 52 may include only the first valve 521 , and the exhaust port 24 may be blocked or at least partially offset from the exhaust port 24 by changing the position of the first valve 521 .

[0065] In some embodiments of the present invention, the exhaust guide 5 includes a switching valve 51, and the volute valve 52 is no longer provided. The switching valve 51 is suitable for translation and lifting to change its position. When the exhaust guide 5 is in the fresh air position, the switching valve 51 separates the second chamber 21 and the common air outlet 42. At this time, the switching valve 51 is constructed as a part of the cavity wall of the second chamber 21; when the exhaust guide 5 is in the exhaust position, the switching valve 51 separates the first chamber 11 and the common air outlet 42. At this time, the switching valve 51 is constructed as a part of the cavity wall of the first chamber 11.

[0066] In some embodiments of the present invention, a fresh air valve 23 is provided at the fresh air outlet 22. When the fresh air valve 23 is opened, the fresh air outlet 22 is opened, and the fresh air outlet 22 connects the external space of the volute body with the second chamber 21; when the fresh air valve 23 is closed, the fresh air outlet 22 is closed.

[0067] In some optional embodiments of the present invention, the fresh air damper 23 is a fresh air louver, which includes multiple blades, each of which is connected to a connecting rod. The fresh air louver can be driven by a first motor to move the connecting rod to rotate the multiple blades around their own mounting axis, thereby opening or closing the fresh air louver and further opening or closing the fresh air outlet 22. To save internal space of the volute body, the first motor can be installed outside the volute body.

[0068] In some other optional embodiments of the present invention, the fresh air valve 23 is a fresh air door plate, which can be hingedly connected to the volute body. The mounting shaft of the fresh air door plate is driven to rotate by a second motor, so as to realize the opening or closing of the fresh air door plate and the opening or closing of the fresh air outlet 22.

[0069] In some embodiments of the present invention, an exhaust valve 13 is provided at the exhaust air inlet 12. When the exhaust valve 13 is opened, the exhaust air inlet 12 is opened, and the exhaust air inlet 12 connects the external space of the volute body with the first chamber 11; when the exhaust valve 13 is closed, the exhaust air inlet 12 is closed.

[0070] In some optional embodiments of the present invention, the exhaust valve 13 is an exhaust louver, which includes multiple blades, each of which is connected to a connecting rod. The exhaust louver can be driven by a third motor to move the connecting rod to rotate the multiple blades around their own mounting axis, thereby opening or closing the exhaust louver and further opening or closing the exhaust air inlet 12. In order to save internal space of the volute body, the first motor can be installed outside the volute body.

[0071] In some other optional embodiments of the present invention, the exhaust valve 13 is an exhaust door plate, which can be hingedly connected to the volute body. The exhaust door plate can be driven by a fourth motor to rotate the mounting shaft of the exhaust door plate, so as to realize the opening or closing of the exhaust door plate and thereby realize the opening or closing of the exhaust air inlet 12.

[0072] In some embodiments of the present invention, the volute body may include a first volute 1 and a second volute 2, the first volute 1 and the second volute 2 being relatively buckled together, a partition plate 3 being provided at the buckled connection between the first volute 1 and the second volute 2, an air guide ring 31 being provided on the partition plate 3, a first chamber 11 being formed in the first volute 1, an exhaust air inlet 12 being provided on the first volute 1, a second chamber 21 being formed in the second volute 2, and a fresh air outlet 22 being provided on the second volute 2. The first volute 1 and the second volute 2 may be fixed by snapping together, or may be connected and fixed using fasteners such as bolts.

[0073] In some embodiments, in order to simplify the parts structure and processing technology, the first volute 1 may include a first main volute and a first sub-volute, the first sub-volute is located between the first main volute and the second volute 2, the exhaust air inlet 12 may be opened on the first sub-volute, and the partition plate 3 is installed and fixed to the first sub-volute.

[0074] Reference Figure 1 、 Figure 3 、 Figure 5 As shown, the air exchange module 10 may include a common air duct 4, which has a hollow channel 41, and a common air outlet 42 is connected to the hollow channel 41 in the common air duct 4. The common air duct 4 and the first volute 1 and the second volute 2 can be connected by a snap-fit ​​structure 7.

[0075] In some embodiments of the present invention, reference Figure 2 、 Figure 4 、 Figure 6 As shown, the air exchange module 10 can also include a fan 61 and a wind wheel 62. The fan 61 is used to drive the wind wheel 62 to rotate. When the wind wheel 62 rotates, it is used to provide driving force for the air to flow in the air exchange module 10. The fan 61 and the wind wheel 62 are arranged in the second chamber 21.

[0076] The shape of the volute valve 52 can enable the air exchange module 10 to maintain a high work efficiency in both the fresh air mode and the exhaust air mode. Figure 11 Two key dimension parameters in the design of the centrifugal air duct of the air exchange module 10 are given. First, the smaller the radius r of the volute, the greater the static pressure and the noise; second, the smaller the volute opening W, the smaller the air volume. In some embodiments of the present invention, refer to Figure 2 、 Figure 4 、 Figure 6 、 Figure 11As shown, the opening of the volute body in the fresh air mode is W1, the opening of the volute body in the exhaust mode is W2, the difference between W1 and W2 does not exceed 5mm, the air outlet tongue radius of the volute body in the fresh air mode is r1, the air outlet tongue radius of the volute body in the exhaust mode is r2, and the difference between r1 and r2 does not exceed 2mm.

[0077] For example, in a specific example, the opening W1 of the volute body in the fresh air mode is 32 mm, the opening W2 of the volute body in the exhaust mode is 28 mm, W1-W2=4 mm, the air outlet volute tongue radius r1 of the volute body in the fresh air mode is 5 mm, and the air outlet volute tongue radius r2 of the volute body in the exhaust mode is 5.5 mm, r2-r1=0.5 mm.

[0078] By designing the volute valve 52 as a double-opening structure, the key parameters of the air duct can be basically consistent during exhaust and intake. By sharing the same air duct, space is saved while also ensuring that the air duct has a high working capacity. In addition, in the fresh air mode, the air outlet of the volute body directly faces the air outlet of the entire air exchange module 10 (i.e., the fresh air outlet 22). In the exhaust mode, the volute valve 52 rotates so that the air outlet of the volute body directly faces the air outlet of the entire air exchange module 10 (i.e., the shared air outlet 42), greatly reducing airflow bending and increasing air volume.

[0079] The following describes the working mode of the air exchange module 10 according to a specific example of the present invention.

[0080] The air exchange module 10 includes a volute body and an exhaust guide 5, wherein the volute body includes a first volute 1 and a second volute 2. The first volute 1 and the second volute 2 are relatively buckled. A partition plate 3 is provided at the buckled connection between the first volute 1 and the second volute 2. An air guide ring 31 is provided on the partition plate 3. A first chamber 11 is formed in the first volute 1, an exhaust air inlet 12 is provided on the first volute 1, a second chamber 21 is formed in the second volute 2, and a fresh air outlet 22 is provided on the second volute 2. A common air outlet 42 is provided on the first volute 1, and the common air outlet 42 is connected to the common air duct 4. The common air duct 4 has a hollow channel 41 therein. The common air outlet 42 is connected to the hollow channel 41 in the common air duct 4. The common air duct 4 faces the outdoors, and the exhaust air inlet 12 and the fresh air outlet 22 face the indoors. Exhaust louvers are provided at the exhaust air inlet 12, and fresh air louvers are provided at the fresh air outlet 22. The exhaust guide 5 includes a switching valve 51, a first valve 521 and a second valve 522. The switching valve 51 is driven by a motor to rise and fall to change its position. The first valve 521 can be driven by a first connecting rod 523 to realize the rotation of the first valve 521. The second valve 522 can be driven by a second connecting rod 524 to realize the rotation of the first valve 521.

[0081] In fresh air mode, air enters from the outdoor side connected to the first volute 1 along the shared air duct 4. At this time, the switching valve 51 is in the down position, at the same height as the second volute 2. The air flows along the surface of the switching valve 51 through the air guide ring 31. The airflow through the air guide ring 31 enters the second volute 2. At this time, the first valve 521 and the second valve 522 are closed, the fresh air louvers are open, and under the action of the rotating wind wheel 62, the air flows through the fresh air louvers and blows into the room.

[0082] In exhaust mode, the drive motors of the first valve 521 and the second valve 522 start to start, driving the first connecting rod 523 and the second connecting rod 524 to rotate. The first valve 521 and the second valve 522 rotate to open in both directions. At the same time, the exhaust louvers in the first volute 1 open, and air flows in from the indoor side. At this time, the switching valve 51 rises, and the air flow turns and flows through the air guide ring 31 and enters the second volute 2. The fresh air louvers in the second volute 2 are closed, so the accelerated air flow cannot flow out from here. At the same time, the first valve 521 and the second valve 522 open outward, and the exhaust port 24 connects the second chamber 21 with the common air port 42. Under the action of the wind wheel 62, the air flow blows towards the opened first valve 521 and the second valve 522. The exhaust port 24 faces the common air port 42, and guides the air flow to the outside through the common air duct 4.

[0083] The ventilation module 10 according to the embodiment of the present invention has a fresh air mode and an exhaust mode, and can freely switch between the suction and exhaust states, and the suction and exhaust functions share the same set of wind wheels 62 and volute body. By rationally designing the profile of the volute body, it is possible to achieve two-way flow switching of the airflow while meeting the working principle of the centrifugal air duct, maximizing the use of the structural space, and achieving considerable exhaust performance without affecting the working efficiency of the fresh air duct. According to different user installation scenarios, the circulation between indoor and outdoor air, as well as the simple indoor air circulation function can be realized.
