[0001] The utility model relates to the technical field of air conditioners, and particularly provides an air conditioner indoor unit and a fresh air module for the air conditioner indoor unit. Background Art

[0002] Traditional household air conditioners include an air conditioner indoor unit and an air conditioner outdoor unit. When the air conditioner is working, it can usually only guide the air circulation indoors, but cannot introduce outdoor fresh air. After running for a period of time, the indoor air quality will decline. To solve the above problems, a fresh air module is generally provided in the existing air conditioner indoor unit, and the fresh air module is used to improve the air quality of the indoor environment, which can refresh the indoor air and effectively improve the customer experience. However, the addition of the fresh air module will occupy the internal space of the air conditioner indoor unit, and the thickness dimensions of the air inlet cavity and the motor volute of the fresh air module largely determine the performance of the fresh air module; the stronger the performance of the fresh air module, the larger the volume of the fresh air module accordingly.

[0003] Some existing fresh air modules of air conditioner indoor units have an outdoor air inlet and an indoor air inlet, so that outdoor air can be filtered by the fresh air module through the outdoor air inlet and then sent indoors, or indoor air can be filtered through the fresh air module through the indoor air inlet and then sent indoors. However, for this double-air-inlet structure, each air inlet needs to have a corresponding opening and closing mechanism to control its opening and closing state, and the opening and closing mechanism will occupy the limited installation space of the air conditioner indoor unit. Summary of the Utility Model

[0004] The utility model aims to solve the above technical problems, that is, to solve the problem that the installation space occupied by the opening and closing mechanism of the existing air inlet is relatively large.

[0012] In some feasible embodiments of the fresh air module for an air conditioner indoor unit described above, the baffle member has a connecting portion, the baffle member is connected to the driving device through the connecting portion, and the connecting portion is provided with a bending structure to adapt to the transition position between the first mounting portion and the second mounting portion.

[0013] In some feasible embodiments of the fresh air module for an air conditioner indoor unit described above, a first rib and a second rib that both extend in the direction of the first mounting portion and are connected end to end are provided on the inner side surface of the cover plate. The first rib is arranged at the edge of the first air inlet and on the side close to the second air inlet, and the second rib is arranged at the edge of the first air inlet and on the side far from the second air inlet. In the installed state, the second rib abuts against the first mounting plane, and there is a gap between the first rib and the first mounting plane for the baffle member to swing.

[0014] In some feasible embodiments of the fresh air module for an air conditioner indoor unit described above, a part of the edge of the baffle member extends in the direction of the cover plate to form a third rib. In the case where the baffle member is in the first working position, the third rib surrounds the outer peripheral side of the first rib.

[0015] In some feasible embodiments of the fresh air module for an air conditioner indoor unit described above, the edge of the baffle member extends in the direction of the first mounting plane to form a fourth rib.

[0016] In some feasible embodiments of the fresh air module for an air conditioner indoor unit described above, there is an included angle between the axis of the driving device in the installed state and the perpendicular line of the mating portion.

[0017] In some feasible embodiments of the fresh air module for an air conditioner indoor unit described above, a fresh air duct connection part is further provided at a position on the outer side surface of the cover plate corresponding to the edge of the first air inlet.

[0018] In the case of adopting the above technical solution, the baffle member can swing between a first working position and a second working position under the drive of the driving device to selectively close the first air inlet or the second air inlet, that is, by setting a single baffle member in the present invention, the opening and closing states of the two air inlets can be controlled; compared with the prior art solution of setting multiple baffle members, the installation space occupied by setting a single opening and closing mechanism in the present invention is smaller, so that the volume of the fresh air module can be reduced as a whole, and the space utilization rate inside the air conditioner indoor unit can be improved. In addition, the cover plate of the present invention is installed on the first installation part. In the installed state, the outer side surface of the cover plate is flush with the part of the air inlet housing corresponding to the edge of the first installation part, realizing the embedded installation of the cover plate.

[0037] As Figure 1 shown, the embodiment of the present utility model provides a fresh air module 1 for a cabinet-type air conditioner indoor unit. The fresh air module 1 includes an air inlet housing 11, a cover plate 12, an opening and closing mechanism 13, etc.

[0038] Specifically, as Figure 1 and Figure 2 shown, the air inlet housing 11 is used to construct the air inlet cavity of the fresh air module 1. The outlet of the air inlet cavity is communicated with the inlet of the fan assembly 2. Outdoor fresh air can enter the air inlet cavity under the drive of the fan device. A filter module for filtering air is arranged in the air inlet cavity to filter the inhaled fresh air. The outer side surface of the air inlet housing 11 has a vertically extending flat portion, and a part of this flat portion is recessed in the direction towards the air inlet cavity to form a first installation portion 111, and the first installation portion 111 is used to install the cover plate 12.

[0039] Continuing to refer to Figure 1 and Figure 2 , the cover plate 12 is installed on the first installation portion 111. In the installed state, the outer side surface of the cover plate 12 is flush with the part of the air inlet housing 11 corresponding to the edge of the first installation portion 111, realizing the flush-mounted installation of the cover plate 12. Such a setting enables the cover plate 12 to be compactly installed on the air inlet housing 11, thereby improving the space utilization rate inside the cabinet-type air conditioner indoor unit.

[0040] The cover plate 12 has a first air inlet 121 and a second air inlet 122 that are communicated with the air inlet cavity. Outdoor air can enter the air inlet cavity through the first air inlet 121, and indoor air can enter the air inlet cavity through the second air inlet 122. The second air inlet 122 is located below the first air inlet 121, and the second air inlet 122 is configured with a grille structure to prevent foreign objects from entering the interior of the air inlet cavity through the second air inlet 122.

[0041] Furthermore, as Figure 2As shown, a fresh air duct connection part 1211 is further provided at a position on the outer side surface of the cover plate 12 corresponding to the edge of the first air inlet 121. The fresh air duct of the cabinet air conditioner indoor unit is connected to the first air inlet 121 through the fresh air duct connection part 1211, so that the fresh air outdoors can enter the air inlet cavity in sequence through the fresh air duct and the first air inlet 121.

[0042] As Figure 1 and Figure 2 shown, the opening and closing mechanism 13 includes a driving device 131 and a swingable baffle member 132. The driving device 131 is specifically a driving motor. The driving device 131 is used to drive the baffle member 132 to swing. The driving device 131 is installed on the outer side surface of the cover plate 12. The baffle member 132 is installed between the cover plate 12 and the first mounting part 111. The baffle member 132 has a connecting part 1323. The baffle member 132 is connected to the driving device 131 through the connecting part 1323. Driven by the driving device 131, the baffle member 132 can swing between a first working position and a second working position to selectively close the first air inlet 121 or the second air inlet 122.

[0043] As Figure 3 shown, when the baffle member 132 swings to the first working position, the baffle member 132 can block and close the first air inlet 121. Correspondingly, the second air inlet 122 is in an open state. At this time, the indoor air can enter the air inlet cavity through the second air inlet 122 for filtering, and finally be delivered to the indoor through the air outlet of the fresh air module 1, so that the fresh air module 1 can circulate and filter the indoor air.

[0044] As Figure 4 shown, when the baffle member 132 swings to the second working position, the baffle member 132 can block and close the second air inlet 122. Correspondingly, the first air inlet 121 is in an open state. At this time, the fresh air outdoors can enter the air inlet cavity through the first air inlet 121 for filtering, and finally be delivered to the indoor through the air outlet of the fresh air module 1, so that the fresh air module 1 can deliver the filtered fresh air to the indoor.

[0045] In the embodiment of the present utility model, by providing a single baffle member 132, the opening and closing states of two air inlets can be controlled. Compared with the prior art solution of providing multiple baffle members 132, the single opening and closing mechanism 13 provided in the embodiment of the present utility model occupies less installation space, so that the volume of the fresh air module 1 can be reduced as a whole, and the space utilization rate inside the indoor unit of the cabinet air conditioner can be improved. In addition, the cover plate 12 in the embodiment of the present utility model is installed on the first installation part 111. In the installed state, the outer side surface of the cover plate 12 is flush with the part of the air inlet housing 11 corresponding to the edge of the first installation part 111, realizing the flush-mounted installation of the cover plate 12. Such a setting enables the cover plate 12 to be compactly installed on the air inlet housing 11, so that the cover plate 12 can make full use of the space of the air inlet housing 11, eliminating the need for a large amount of installation space reserved specifically for installing the cover plate 12 with a small size in the prior art, thereby improving the space utilization rate inside the indoor unit of the cabinet air conditioner. In addition, such a setting also increases the gap between the cover plate 12 and the rear panel frame of the indoor unit of the cabinet air conditioner. Since the rear air inlet grille of the indoor unit of the cabinet air conditioner is provided on the rear panel frame, the above setting in the embodiment of the present utility model is beneficial to the air circulation inside the indoor unit of the cabinet air conditioner, reduces the air flow resistance, and improves the air exchange efficiency of the fresh air module 1.

[0046] As Figure 2 shown, the first installation part 111 includes a first installation plane, and the baffle member 132 is clamped between the cover plate 12 and the first installation plane. A part of the first installation plane recesses further towards the air inlet cavity to form a second installation part 1113. A mating part 123 that recesses towards the air inlet cavity is also formed on the cover plate 12. The mating part 123 corresponds to the second installation part 1113, and the driving device 131 is installed on the mating part 123 corresponding to the second installation part 1113. Through the above setting, the driving device 131 can be compactly installed on the cover plate 12, so that the driving device 131 can make full use of the space on the cover plate 12, reducing the installation space occupied by the driving device 131 in the front-rear direction when installed inside the indoor unit of the cabinet air conditioner, and improving the space utilization rate inside the indoor unit of the cabinet air conditioner. At the same time, the gap between the driving device 131 and the rear panel frame of the indoor unit of the cabinet air conditioner is increased. Since the rear air inlet grille of the indoor unit of the cabinet air conditioner is provided on the rear panel frame, the above setting in the embodiment of the present utility model is beneficial to the air circulation inside the indoor unit of the cabinet air conditioner, reduces the air flow resistance, and improves the air exchange efficiency of the fresh air module 1.

[0047] Further, as Figure 5 and Figure 9As shown, the connecting portion 1323 is provided with a bending structure 13231 to adapt to the transition positions of the first mounting portion 111 and the second mounting portion 1113; specifically, a part of the connecting portion 1323 is recessed toward the air inlet chamber relative to the main body portion of the baffle member 132 to form the bending structure 13231. Through the above arrangement, the bending structure 13231 of the connecting portion 1323 can be compactly mounted between the mating portion 123 and the second mounting portion 1113, so that the bending structure 13231 can make full use of the space between the mating portion 123 and the second mounting portion 1113.

[0048] In some specific embodiments, there is an included angle between the axis of the driving device 131 in the installed state and the perpendicular line of the mating portion 123, so that the driving device 131 is in an inclined state; specifically, there is an included angle between the axis of the main body portion of the driving device 131 and the perpendicular line of the mating portion 123, and the included angle is 1 to 20°, preferably 15°. Through the above arrangement, the installation space occupied by the driving device 131 in the indoor unit of the cabinet air conditioner is further reduced. In addition, when there are water droplets on the outer side surface of the main body portion of the driving device 131, since the main body portion of the driving device 131 is in an inclined state, the water droplets are easy to flow downward along its inclined direction and drip, so as to prevent the water droplets from entering the inside of the driving device 131, having a certain waterproof effect.

[0049] As Figure 3 and Figure 4 As shown, the inner side surface of the cover plate 12 is provided with a first rib 124 and a second rib 125 that both extend toward the direction of the first mounting portion 111 and are connected end to end. The first rib 124 and the second rib 125 are both in an arc structure. The first rib 124 is arranged at the edge of the first air inlet 121 and on the side close to the second air inlet 122, and the second rib 125 is arranged at the edge of the first air inlet 121 and on the side far from the second air inlet 122. When the cover plate 12 is in the installed state, the second rib 125 abuts against the first mounting plane, and there is a gap between the first rib 124 and the first mounting plane for the baffle member 132 to swing. Through the above arrangement, in the case where the baffle member 132 is in the first working position and the first air inlet 121 is in the closed state, the first rib 124 and the second rib 125 can reduce the gap between the baffle member 132 and the edge of the first air inlet 121, improving the sealing performance of the edge of the first air inlet 121.

[0050] Furthermore, as Figure 6As shown, a part of the edge of the baffle member 132 extends towards the cover plate 12 to form a third rib 1321. When the baffle member 132 is in the first working position such that the first air inlet 121 is in the closed state, the third rib 1321 surrounds the outer peripheral side of the first rib 124. Through the above arrangement, when the baffle member 132 is in the first working position such that the first air inlet 121 is in the closed state, the third rib 1321 can reduce the gap between the baffle member 132 and the edge of the first air inlet 121, and can cooperate with the first rib 124 correspondingly, further improving the sealing performance of the edge of the first air inlet 121.

[0051] As Figure 2 shown, the first installation plane has a fresh air inlet 1111 and an indoor air inlet 1112 that communicate with the air inlet chamber. The fresh air inlet 1111 corresponds to the first air inlet 121, and the indoor air inlet 1112 corresponds to the second air inlet 122.

[0052] As Figure 7 shown, when the baffle member 132 swings to the first working position, the baffle member 132 can block and close the first air inlet 121 and the fresh air inlet 1111. Correspondingly, the second air inlet 122 and the indoor air inlet 1112 are in the open state. At this time, the indoor air can enter the air inlet chamber through the second air inlet 122 and the indoor air inlet 1112 in sequence for filtration, and finally be delivered to the indoor through the air outlet of the fresh air module 1, so that the fresh air module 1 can circulate and filter the indoor air.

[0053] As Figure 8 shown, when the baffle member 132 swings to the second working position, the baffle member 132 can block and close the second air inlet 122 and the indoor air inlet 1112. Correspondingly, the first air inlet 121 and the fresh air inlet 1111 are in the open state. At this time, the fresh outdoor air can enter the air inlet chamber through the first air inlet 121 and the fresh air inlet 1111 in sequence for filtration, and finally be delivered to the indoor through the air outlet of the fresh air module 1, so that the fresh air module 1 can deliver the filtered fresh air to the indoor.

[0054] Furthermore, as Figure 6 shown, the edge of the baffle member 132 extends towards the first installation plane to form a fourth rib 1322. Specifically, as Figure 7 shown, when the baffle member 132 is in the first working position such that the first air inlet 121 and the fresh air inlet 1111 are in the closed state, the fourth rib 1322 surrounds the edge of the fresh air inlet 1111, thereby reducing the gap between the baffle member 132 and the edge of the fresh air inlet 1111 and improving the sealing performance of the edge of the fresh air inlet 1111. As Figure 8As shown, when the baffle member 132 is in the second working position so that the second air inlet 122 and the indoor air inlet 1112 are in the closed state, the fourth rib 1322 surrounds the edge of the indoor air inlet 1112, thereby reducing the gap between the baffle member 132 and the edge of the indoor air inlet 1112 and improving the sealing performance of the edge of the indoor air inlet 1112. In addition, the main body portion of the baffle member 132 can be separated from the first mounting plane by the fourth rib 1322, which can avoid the situation of large-area contact during the swinging process of the baffle member 132, thereby facilitating the smooth swinging of the baffle member 132.

[0055] An embodiment of the present invention also provides a cabinet-type air conditioner indoor unit, as Figure 10 shown. The cabinet-type air conditioner indoor unit includes the fresh air module 1 and the fan assembly 2 in any one of the above. The fan assembly 2 includes a fan housing 21. The fan housing 21 is connected to the air inlet housing 11. The fan housing 21 is configured with a fan chamber, and the fan chamber is communicated with the air inlet chamber. A fan device is arranged in the fan chamber. Under the action of the fan device, the air in the air inlet chamber can be transported to the room through the fan chamber.

[0056] Specifically, the cabinet-type air conditioner indoor unit further includes a front panel frame and a rear panel frame arranged opposite to the front panel frame. The fresh air module 1 is close to the rear panel frame, and the rear panel frame is configured with a rear air inlet grille through which the air in the room can enter the interior of the cabinet-type air conditioner indoor unit.

[0057] It can be understood that since the cabinet-type air conditioner indoor unit is configured with the above-mentioned fresh air module 1 for the cabinet-type air conditioner indoor unit, it has all the technical effects of the above-mentioned fresh air module 1, which will not be elaborated here.

[0058] So far, the technical solution of the present invention has been described in combination with the preferred embodiments shown in the drawings. However, it is easy for those skilled in the art to understand that the protection scope of the present invention is obviously not limited to these specific embodiments. Without departing from the principle of the present invention, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will fall within the protection scope of the present invention.
