[0026] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0027] Reference below Figures 1 to 4 An air conditioner indoor unit 100 according to an embodiment of the first aspect of the present invention will be described.

[0028] like Figure 1As shown, according to the first aspect of the present invention, the air-conditioning indoor unit 100 is arranged on the upper side of a wall window, and the window is provided with an openable window 200. The air-conditioning indoor unit 100 includes: a shell 1, a fan assembly 2, a fresh air guide plate 17, a driving device (not shown in the figure) and a controller (not shown in the figure).

[0029] Specifically, an air flow channel 11 is formed in the shell 1, and a return air port 14, a fresh air port 13 and an air outlet 15 are formed on the shell 1, wherein the fresh air port 13 is formed at the bottom of the shell 1, and the fresh air port 13 is arranged adjacent to the window 200, and the return air port 14, the fresh air port 13 and the air outlet 15 are all connected to the air flow channel 11.

[0030] The fan assembly 2 is arranged in the air flow channel 11, and the fan assembly 2 can be used to drive the air flow from the fresh air inlet 13 and / or the return air inlet 14 to the air outlet 15. That is to say, the fan assembly 2 can be used to drive the outdoor air flow from the fresh air inlet 13 to the air outlet 15, and the fan assembly 2 can also be used to drive the indoor air flow from the return air inlet 14 to the air outlet 15. The fan assembly 2 can also drive the indoor air from the return air inlet 14 to the air outlet 15 while driving the outdoor air from the fresh air inlet 13 to the air outlet 15.

[0031] The fresh air guide plate 17 can be arranged at the position of the fresh air outlet 13, and the fresh air guide plate 17 can be used to open and close the fresh air outlet 13; the driving device is connected to the fresh air guide plate 17, and the driving device can be used to adjust the opening degree of the fresh air guide plate 17 to open the fresh air outlet. The controller can be connected to the driving device for communication, and the controller can control the opening degree of the fresh air guide plate 17 according to the carbon dioxide concentration in the room.

[0032] For example, when the indoor carbon dioxide concentration is low, the user opens the window 200 and closes the curtains. The closed curtains serve to isolate the indoor and outdoor environments. The controller can control the fresh air guide plate 17 to open. At this time, the fan assembly 2 can directly introduce outdoor fresh air into the room from the fresh air inlet 13. At the same time, the return air inlet 14 directly enters the indoor circulating air, thereby ensuring that the air conditioner can also play the role of exchanging fresh air in the conventional cooling or heating mode; when the indoor carbon dioxide concentration is in a normal state, the user can close the window 200. At the same time, the controller can control the fresh air guide plate 17 to close. At this time, the fan assembly 2 only drives the indoor air flow from the return air inlet 14 to the air outlet 15 to realize the circulation of indoor air.

[0033] Therefore, the air-conditioning indoor unit 100 of this embodiment achieves the purpose of fresh air exchange by utilizing the existing indoor environment and the indoor scene, thereby abandoning the traditional duct-induced air intake mode. On the one hand, it does not require wall holes and duct air intake, and the installation form is simple. On the other hand, it can achieve a large fresh air volume without being restricted by the pipe diameter.

[0034] According to the air-conditioning indoor unit 100 of the present invention, the fresh air inlet 13, the return air inlet 14 and the air outlet 15 are integrated on the shell 1, and the fresh air inlet 13, the air flow channel 11 and the air outlet 15 form a fresh air intake channel, and the return air inlet 14, the air flow channel 11 and the air outlet 15 form an indoor return air channel, so that the air-conditioning indoor unit 100 can not only supplement fresh air for the room, but also realize indoor air circulation. At the same time, the air-conditioning indoor unit 100 achieves the purpose of fresh air exchange by utilizing the existing indoor environment and the indoor scene, and abandons the traditional duct-induced air mode. On the one hand, there is no need for wall holes and ducts to induce air, and the installation form is simple. On the other hand, a large amount of fresh air can be achieved without being restricted by the pipe diameter.

[0035] Furthermore, the air conditioner indoor unit 100 may include: a carbon dioxide sensor (not shown in the figure), a controller may be connected to the carbon dioxide sensor, the carbon dioxide sensor may be used to monitor the carbon dioxide concentration in the room, and feed the monitored concentration back to the controller, which automatically determines whether the fresh air guide plate 17 needs to be opened.

[0036] According to some embodiments of the present invention, reference Figures 1 to 3 A avoidance opening 16 is formed on the outer surface of the bottom of the shell 1, and the avoidance opening 16 is recessed upward. The avoidance opening 16 passes through the shell 1 along the length direction of the shell 1. The fresh air outlet 13 is formed on the rear side of the avoidance opening 16. The avoidance opening 16 is suitable for cooperating with the curtain of the window to separate the fresh air outlet 13 located outside the curtain from the indoor space located inside the curtain.

[0037] Thus, the bottom of the housing 1 is arranged in the front-to-back direction (such as Figure 1 The width of the opening 13 (in the front-to-back direction shown in the figure) is just smaller than the width of the gap between the curtain railing and the wall. When the window 200 is in an open state, the curtain is opened and completely covers the window 200, and the fresh air outlet 13 can just extend into the narrow passage formed between the curtain and the wall. At this time, the space between the opened curtain and the window is formed into a fresh air zone because it is connected to the outdoor space, and the indoor space within the curtain is formed into an indoor environment zone. The opened curtain can isolate the indoor and outdoor environments. Therefore, the fresh air outlet 13 can directly introduce fresh air from the fresh air zone to the indoor environment zone. At the same time, the indoor and outdoor temperatures can be isolated through the curtain.

[0038] According to some embodiments of the present invention, reference Figures 1 to 3 The rear side portion of the bottom wall of the housing 1 protrudes downward to form a protrusion 12, and a fresh air outlet 13 is formed on the protrusion 12. The fresh air outlet 13 is in the thickness direction ( Figure 1 ) passes through the raised portion 12, for example Figure 1As shown, the front edge of the raised portion 12 can be formed as the rear edge of the avoidance opening 16. Thus, the inner wall of the raised portion 12 can be formed as a part of the airflow channel 11, thereby guiding the airflow coming in from the window 200 into the airflow channel 11. In addition, when the curtain is closed and completely covers the window 200, the raised portion 12 provided with the fresh air outlet 13 can just extend into the narrow passage formed between the curtain and the wall. At this time, the space between the opened curtain and the window is formed into a fresh air zone because it is connected to the outdoor space, and the indoor space within the curtain is formed into an indoor environment zone. The opened curtain can play a role in isolating the indoor and outdoor environments. Thus, the fresh air outlet 13 can directly introduce fresh air from the fresh air zone to the indoor environment zone, and at the same time, the indoor and outdoor temperature isolation can be achieved through the curtain.

[0039] Of course, the present invention is not limited thereto, and the bottom wall of the housing 1 may also be formed as a straight bottom wall, and the fresh air outlet 13 may be directly formed on the straight bottom wall.

[0040] According to some embodiments of the present invention, a fresh air filter (not shown) is provided on the inner side of the fresh air outlet 13, and the fresh air filter covers the fresh air outlet 13 in the flow direction of the airflow, thereby, the fresh air filter can filter out dust or other impurities in the outdoor fresh air.

[0041] In some embodiments of the present invention, the return air outlet 14 includes a plurality of return air holes (not shown), and the plurality of return air holes are arranged at intervals on the front side of the shell 1 in the length direction and the width direction of the shell 1. The air outlet 15 is formed on the front side of the shell 1, and the air outlet 15 can be located above the return air outlet 14, or the air outlet 15 can be formed on the top of the shell 1. Thus, the layout of the air flow channel 11 can be optimized and the internal structure of the air-conditioning indoor unit 100 can be simplified.

[0042] Furthermore, the cross-sectional area of ​​the return air hole located at the lower front side of the housing 1 is greater than the cross-sectional area of ​​the return air hole located at the upper front side of the housing 1. In other words, among the multiple return air holes provided at the return air outlet 14, the cross-sectional area of ​​the return air hole at the lower side is greater than the cross-sectional area of ​​the return air hole at the upper side, so that the airflow at the return air hole adjacent to the air outlet 15 and the airflow at the air outlet 15 can be avoided as much as possible from interfering with each other.

[0043] Furthermore, in the direction from bottom to top, the cross-sectional areas of the plurality of return air holes gradually decrease, which, on the one hand, simplifies the structure, and on the other hand, avoids interference between the airflow of the return air holes adjacent to the air outlet 15 and the airflow of the air outlet 15 .

[0044] In some embodiments, the ratio between the air inlet area of ​​the fresh air outlet 13 and the return air area of ​​the return air outlet 14 is in the range of 1 / 4 to 3 / 4. In this way, the proportional adjustment and distribution of fresh air or return air is achieved through the double return air outlets of the air-conditioning indoor unit 100 itself (i.e., the fresh air outlet 13 and the return air outlet 14). Preferably, the ratio of the air inlet area of ​​the fresh air outlet 13 to the area of ​​the return air outlet 14 is 1:2. In this way, the influence of the fresh air on the normal functions of the air-conditioning indoor unit 100 can be weakened as much as possible.

[0045] In some embodiments of the present invention, reference Figures 1 to 3 The air conditioner indoor unit 100 may further include: a heat exchanger 3. Specifically, the heat exchanger 3 is arranged in the air flow channel 11, and the heat exchanger 3 includes a first heat exchange part 31 and a second heat exchange part 32. The first heat exchange part 31 is arranged between the fresh air inlet 13 and the air outlet 15, and the second heat exchange part 32 is arranged between the return air inlet 14 and the air outlet 15. In addition, a water receiving tray is arranged below the first heat exchange part 31 and the second heat exchange part 32. The water receiving tray can collect condensation generated at the first heat exchange part 31 and the second heat exchange part 32 to prevent the condensation from gathering into a water flow and flowing in the housing 1. At the same time, the first heat exchange part 31 can exchange heat with the air entering the room from the fresh air inlet 13, and the second heat exchange part 32 can exchange heat with the air circulating in the room. At the same time, the structure of the air conditioner indoor unit 100 can be simplified.

[0046] According to some embodiments of the present invention, reference Figures 1 to 3 The air conditioner indoor unit 100 may further include an air guide plate 4. Specifically, the air guide plate 4 is disposed at the air outlet 15, and the air guide plate 4 can be used to open and close the air outlet 15. At the same time, the air guide plate 4 can adjust the air outlet angle of the air outlet 15.

[0047] Further, refer to Figures 1 to 3 The air conditioner indoor unit 100 may further include: a wind sweeping louver 5. The wind sweeping louver 5 is disposed at the air outlet 15 and located inside the air guide plate 4, so that the wind sweeping louver 5 can adjust the air outlet angle of the air conditioner indoor unit 100.

[0048] According to some embodiments of the present invention, reference Figures 1 to 3 , the fresh air guide plate 17 may include: a plurality of fresh air louvers 171. Specifically, the plurality of fresh air louvers 171 may be rotatably arranged at the fresh air outlet position, the plurality of fresh air louvers 171 may extend along the length direction of the housing, and the plurality of fresh air louvers 171 may be arranged at intervals in the front-to-back direction. Thus, the opening and closing of the fresh air inlet 13, the angle of the fresh air inlet, and the volume of the fresh air inlet may be controlled by controlling the rotation angle of the plurality of fresh air louvers 171.

[0049] Furthermore, the fresh air guide plate 17 may further include: a fresh air connecting rod (not shown). Specifically, the fresh air connecting rod is rotatably connected to the multiple fresh air louvers 171, so that the fresh air louver 171 can drive the multiple fresh air louvers 171 to rotate synchronously.

[0050] According to some embodiments of the present invention, when the indoor carbon dioxide concentration M is greater than the upper concentration threshold M0, the opening of the fresh air guide plate 17 is the maximum; when the indoor carbon dioxide concentration M is less than the lower concentration threshold M1, the fresh air guide plate 17 closes the fresh air outlet; when the indoor carbon dioxide concentration M is between the upper concentration threshold M0 and the lower concentration threshold M1, the fresh air guide plate 17 opens to a predetermined opening.

[0051] That is to say, an upper concentration threshold M0 and a lower concentration threshold M1 can be set in advance for the controller of the air-conditioning indoor unit. When the indoor carbon dioxide concentration M is higher than the upper concentration threshold M0, the controller controls the opening angle of the fresh air guide plate 17 to the maximum state, so that the indoor air conditioner 100 can quickly and efficiently take in fresh air; when the indoor carbon dioxide concentration M is lower than the lower concentration threshold M1, the controller controls the fresh air guide plate 17 to close, and at this time the indoor air conditioner 100 only circulates and adjusts the temperature of the indoor air; when the indoor carbon dioxide concentration M is between the upper concentration threshold M0 and the lower concentration threshold M1, the controller can control the fresh air guide plate 17 to open a certain angle to achieve proportional adjustment and distribution of fresh air and return air.

[0052] Next, an air conditioner according to a second aspect of the present invention will be described.

[0053] An air conditioner according to a second aspect of the present invention includes the air conditioner indoor unit 100 according to the first aspect of the present invention.

[0054] According to the air conditioner of the present invention, by setting the air conditioner indoor unit 100 of the first aspect mentioned above, on the one hand, it is possible to save the need for drilling a wall hole, and on the other hand, through the double return air outlets of the air conditioner itself (i.e., the fresh air outlet 13 and the return air outlet 14 mentioned above), the proportional adjustment and distribution of fresh air or return air can be achieved.

[0055] Reference below Figures 1 to 4 A specific embodiment of the air conditioner according to the second aspect of the present invention is described.

[0056] The air conditioner according to the second aspect of the present invention comprises the air conditioner indoor unit 100 according to the first aspect of the present invention, and the air conditioner indoor unit 100 comprises: a housing 1, a fan assembly 2, a heat exchanger 3, a fresh air guide plate 17, a driving device and a controller.

[0057] An air flow channel 11 is formed in the shell 1, and a return air port 14, a fresh air port 13 and an air outlet 15 connected to the air flow channel 11 are formed on the shell 1. The return air port 14 is formed on the front side of the shell 1, and the fresh air port 13 is formed at the bottom of the shell 1 and arranged adjacent to the window. A fresh air guide plate 17 can be arranged at the fresh air port 13, and a driving device is connected to the fresh air guide plate 17 to adjust the opening of the fresh air guide plate 17 to open the fresh air port 13; a controller is communicatively connected to the driving device, and the controller can control the opening of the fresh air guide plate 17 according to the indoor carbon dioxide concentration M; an upwardly concave avoidance port 16 is formed on the outer side of the bottom of the shell 1, and the avoidance port 16 penetrates the shell 1 along the length direction of the shell 1, and the fresh air outlet 13 is formed on the rear side of the avoidance outlet 16; the rear side part of the bottom wall of the shell 1 protrudes downward to form a protrusion 12, and the fresh air outlet 13 is formed on the protrusion 12 and penetrates the protrusion 12 in the thickness direction. A fresh air filter is provided on the inner side of the fresh air outlet 13, and the fresh air filter covers the fresh air outlet 13 in the flow direction of the airflow; the heat exchanger 3 is arranged in the airflow channel 11, and the heat exchanger 3 includes a first heat exchange part 31 and a second heat exchange part 32, the first heat exchange part 31 is arranged between the fresh air outlet 13 and the air outlet 15, and the second heat exchange part 32 is arranged between the return air outlet 14 and the air outlet 15.

[0058] The working principle of the air conditioner is as follows: the air conditioner indoor unit 100 is arranged on the upper side of the wall window, and the window is provided with an openable window 200. The air conditioner indoor unit 100 adopts the upper air outlet mode, and the fresh air outlet 13 can cooperate with the indoor curtain to effectively isolate the indoor environment. When the indoor carbon dioxide concentration M is higher than the upper concentration threshold M0, the controller opens the fresh air guide plate 17, and the user opens the window 200. At this time, the closed curtains serve to isolate the indoor and outdoor environments. The fresh air outlet 13 directly introduces fresh air from the outside. At the same time, the fresh air outlet 13 is provided with a filter component, which can filter the fresh air introduced from the outside. The return air outlet 14 directly enters the indoor circulating air. After the above two air flows pass through the heat exchanger 3, they are blown out from the air outlet 15, thereby ensuring that the air conditioner can also play the role of exchanging fresh air in the conventional cooling or heating mode; when the indoor carbon dioxide concentration M is lower than the lower concentration threshold M1, the controller closes the fresh air guide plate 17, and the user can close the window 200. The fan assembly 2 can only drive the indoor air flow from the return air outlet 14 into the air flow channel 11, and flow to the air outlet 15 through the air flow channel 11, so as to realize the circulation of indoor air.
