[0002] With the development of science and technology, people's living standards have been continuously improved. As an electrical appliance for cooling in summer and heating in winter, air conditioners have become increasingly indispensable in people's lives, work, entertainment and other scenarios. And in order to meet the needs of users, the functions of air conditioners are also constantly innovating.

[0003] Currently, in the prior art, in order to meet the requirements of the aesthetics of the indoor space of users, an indoor unit of an air conditioner that is installed in a cabinet in the indoor space has emerged. However, after the indoor unit of the air conditioner is installed in the cabinet, there are gaps between the left and right ends of the indoor unit and the inner walls of the cabinet, and it is very difficult to adjust the gaps at the left and right ends of the indoor unit of the air conditioner evenly. And after the indoor unit of the air conditioner is placed in place in the cabinet, if other parts of the air conditioner need to be adjusted or the indoor unit of the air conditioner vibrates slightly during subsequent use, it will cause the indoor unit of the air conditioner to displace in the cabinet, and then the uniformity of the gaps at the left and right ends of the indoor unit of the air conditioner will be damaged again.

[0048] Figure 7 It is a cross-sectional schematic diagram of the indoor unit of the air conditioner according to an embodiment of the present invention, where Figure 7 The thick solid arrow in represents a schematic diagram of the flow path of the air flow in the housing.

[0049] Refer to Figure 1 , Figure 2 and Figure 3 , in this embodiment, the indoor unit 100 of the air conditioner is used to be embedded in the cabinet 200, and the indoor unit 100 of the air conditioner includes a housing 110 and a positioning structure 120. The positioning structure 120 includes a first telescopic rod 121 and a second telescopic rod 122.

[0050] The housing 110 is used to be arranged in the embedding cavity 210 of the cabinet 200.

[0051] The right end of the first telescopic rod 121 is telescopically inserted through the left end of the housing 110, and the left end of the first telescopic rod 121 is used to abut against the left inner wall of the embedding cavity 210.

[0052] The right end of the second telescopic rod 122 is telescopically inserted through the right end of the housing 110, and the left end of the second telescopic rod 122 is used to abut against the right inner wall of the embedding cavity 210.

[0053] The positioning structure 120 is used to adjust the distance between the housing 110 and the left and right inner walls of the embedding cavity 210 by adjusting the telescopic amounts of the first telescopic rod 121 and the second telescopic rod 122, and to maintain the distance between the housing 110 and the left and right inner walls of the embedding cavity 210 by keeping the telescopic amounts of the first telescopic rod 121 and the second telescopic rod 122.

[0054] Since for the indoor unit 100 of the air conditioner of the present utility model, a first telescopic rod 121 and a second telescopic rod 122 are correspondingly arranged at the left and right ends of the housing 110. The right end of the first telescopic rod 121 is telescopically inserted through the left end of the housing 110, and the left end of the first telescopic rod 121 is used for abutting against the left inner wall of the embedding cavity 210. The right end of the second telescopic rod 122 is telescopically inserted through the right end of the housing 110, and the left end of the second telescopic rod 122 is used for abutting against the right inner wall of the embedding cavity 210.

[0055] Furthermore, when it is necessary to adjust the gaps at the left and right ends of the indoor unit 100 of the air conditioner, compared with only relying on the observation and estimation of the installation operator and manually adjusting the gaps at the left and right ends of the indoor unit 100 of the air conditioner, in this embodiment, the telescopic amounts of the first telescopic rod 121 and the second telescopic rod 122 can be adjusted to assist in fine adjustment, so as to easily adjust the gaps at the left and right ends of the indoor unit 100 of the air conditioner to be uniform.

[0056] And after the adjustment is in place, the telescopic amounts of the first telescopic rod 121 and the second telescopic rod 122 no longer change, keeping the housing 110 of the indoor unit 100 of the air conditioner in the current adjusted position, and ensuring that the gaps at the left and right ends of the indoor unit 100 of the air conditioner do not change during subsequent assembly and use.

[0057] Therefore, for the indoor unit 100 of the air conditioner of the present utility model, the difficulty of adjusting the gaps at the left and right ends of the indoor unit 100 of the air conditioner to be uniform is reduced, and the uniformity of the gaps at the left and right ends of the indoor unit 100 of the air conditioner during subsequent assembly and use is ensured, so as to ensure the aesthetics of the indoor unit 100 of the air conditioner installed in the indoor space and ensure the user experience.

[0058] Refer to Figure 1 、 Figure 2 、 Figure 3 and Figure 4 , in this embodiment, the housing 110 includes a surrounding frame 113 and a front cover 114.

[0059] The front cover 114 is buckled on the front end of the surrounding frame 113.

[0060] It should be understood that since the indoor unit 100 of the air conditioner in this embodiment is an embedded solution, the space between the indoor unit 100 of the air conditioner and the cabinet 200 is narrow. If the indoor unit 100 of the air conditioner fails and needs to be repaired or maintained, the entire indoor unit 100 of the air conditioner has to be disassembled from the cabinet 200, then repaired or maintained, and then the indoor unit 100 of the air conditioner is installed back into the cabinet after the repair or maintenance. In this way, the whole process is complex and cumbersome, increasing the workload of repair or maintenance.

[0061] Furthermore, the housing 110 can be designed in a form where the surrounding frame 113 and the front cover 114 are snap-fitted. When the indoor unit 100 of the air conditioner needs to be repaired or maintained, the front cover 114 can be disassembled, and the indoor unit 100 of the air conditioner can be directly repaired or maintained. After the repair or maintenance is completed, the front cover 114 is reinstalled into the surrounding frame 113 and the cabinet 200.

[0062] Therefore, designing the housing 110 in a form where the surrounding frame 113 and the front cover 114 are snap-fitted can effectively reduce the difficulty of subsequent repair or maintenance of the indoor unit 100 of the air conditioner.

[0063] Refer to Figure 1 、 Figure 2 、 Figure 3 and Figure 4 In the first implementation manner of this embodiment, a first telescopic hole 111 corresponding to the first telescopic rod 121 is provided at the left end of the housing 110, the first telescopic rod 121 is disposed through the first telescopic hole 111, a second telescopic hole 112 corresponding to the second telescopic rod 122 is provided at the right end of the housing 110, and the second telescopic rod 122 is disposed through the second telescopic hole 112.

[0064] It can be understood that due to the provision of the first telescopic hole 111 and the second telescopic hole 112, the first telescopic rod 121 and the second telescopic rod 122 can be disposed on the housing 110.

[0065] Refer to Figure 3 and Figure 5 In this implementation manner, the positioning structure 120 further includes a first threaded portion 1231 and a second threaded portion 1241.

[0066] The first threaded portion 1231 is provided at the left end of the housing 110, and the first threaded portion 1231 is sleeved on the first telescopic rod 121, and a thread matching the first threaded portion 1231 is provided on the first telescopic rod 121 to perform a telescopic movement when the first telescopic rod 121 rotates around the rotation axis.

[0067] The second threaded portion 1241 is provided at the right end of the housing 110, and the second threaded portion 1241 is sleeved on the second telescopic rod 122, and a thread matching the second threaded portion 1241 is provided on the second telescopic rod 122 to perform a telescopic movement when the second telescopic rod 122 rotates around the rotation axis.

[0068] It can be understood that through the design of the first threaded portion 1231 and the second threaded portion 1241, the first telescopic rod 121 and the second telescopic rod 122 can perform telescopic actions. The first threaded portion 1231 and the second threaded portion 1241 cooperate with the first telescopic hole 111 and the second telescopic hole 112, so that the first telescopic rod 121 and the second telescopic rod 122 can be telescopically inserted through the left end and the right end of the housing 110, so as to further enable the positioning structure 120 to assist in adjusting and maintaining the flash seams at the left and right ends of the air conditioner indoor unit 100.

[0069] In some other embodiments, the first threaded portion 1231 is located in the first telescopic hole 111, and the second threaded portion 1241 is located in the second telescopic hole 112.

[0070] It can be understood that threads can be directly formed on the walls of the first telescopic hole 111 and the second telescopic hole 112 on the housing 110 to form the first threaded portion 1231 and the second threaded portion 1241. The first threaded portion 1231 and the second threaded portion 1241 are used to drive the first telescopic rod 121 to perform telescopic movement when the first telescopic rod 121 and the second telescopic rod 122 rotate around the rotation axis.

[0071] Refer to Figure 3 and Figure 5 , in this embodiment, the positioning structure 120 further includes a first nut 123 and a second nut 124.

[0072] The first nut 123 is arranged at the left end of the housing 110 corresponding to the first telescopic hole 111, and the first threaded portion 1231 is located on the first nut 123.

[0073] The second nut 124 is arranged at the right end of the housing 110 corresponding to the second telescopic hole 112, and the second threaded portion 1241 is located on the second nut 124.

[0074] It can be understood that since the thickness of the housing 110 is relatively thin, if the first threaded portion 1231 and the second threaded portion 1241 are directly formed in the first telescopic hole 111 and the second telescopic hole 112, the pitch of the first threaded portion 1231 and the second threaded portion 1241 may be relatively short. During the process of the positioning structure 120 adjusting the left and right movement of the air conditioner indoor unit 100, or during the subsequent assembly of the air conditioner indoor unit 100 and the process of using the air conditioner indoor unit 100, the housing 110 and the first threaded portion 1231 and the second threaded portion 1241 may not be able to support the adjustment of the left and right movement of the air conditioner indoor unit 100, and may not be able to complete the positioning and holding of the air conditioner indoor unit 100.

[0075] Furthermore, by adding a first nut 123 and a second nut 124, it is possible to ensure that the first threaded portion 1231 and the second threaded portion 1241 can have a longer pitch to support the adjustment of the left - right movement of the air - conditioner indoor unit 100 and the positioning and holding of the air - conditioner indoor unit 100.

[0076] Therefore, by adding a first nut 123 and a second nut 124, the stability of the telescopic connection between the first telescopic rod 121 and the second telescopic rod 122 and the housing 110 can be ensured, the stability of the process of realizing the uniformity of the gaps at the left and right ends of the air - conditioner indoor unit 100 through the positioning structure 120 can be ensured, and the stability of the positioning and holding of the positioning structure 120 during the subsequent assembly of the air - conditioner indoor unit 100 and the use of the air - conditioner indoor unit 100 can be ensured.

[0077] Refer to Figure 3 and Figure 5 In this embodiment, the housing 110 is a metal part; and the first nut 123 and the second nut 124 are spot - welded to the housing 110.

[0078] It can be understood that since the housing 110 is set as a metal part, such as a sheet metal part, the first nut 123 and the second nut 124 can be spot - welded to the housing 110 by spot - welding, so as to ensure the connection stability between the first nut 123 and the second nut 124 and the housing 110, and further ensure the stability of the process of realizing the uniformity of the gaps at the left and right ends of the air - conditioner indoor unit 100 through the positioning structure 120, and the stability of the positioning and holding of the positioning structure 120 during the subsequent assembly of the air - conditioner indoor unit 100 and the use of the air - conditioner indoor unit 100.

[0079] Specifically, the first nut 123 and the second nut 124 can be arranged outside the housing 110. However, arranging the first nut 123 and the second nut 124 outside the housing 110 will damage the aesthetics of the air - conditioner indoor unit 100. And since the gaps between the two ends of the air - conditioner indoor unit 100 and the cabinet 200 may be very narrow, arranging the first nut 123 and the second nut 124 outside the housing 110 will affect the overall length dimension of the air - conditioner indoor unit 100 and affect the installation of the air - conditioner indoor unit 100 in the cabinet 200.

[0080] Refer to Figure 3 and Figure 5 In this embodiment, the first nut 123 and the second nut 124 are arranged inside the housing 110. To ensure the aesthetics of the air - conditioner indoor unit 100 and improve the user experience. At the same time, it will not affect the installation of the indoor unit in the cabinet 200.

[0081] Refer to Figure 3 andFigure 5 , in this embodiment, the first telescopic hole 111 is located at the left end of the surrounding frame 113, and the second telescopic hole 112 is located at the right end of the surrounding frame 113.

[0082] It can be learned from the following embodiments that since the surrounding frame 113 bears the gravity of the air conditioner indoor unit 100, further, the first telescopic hole 111 and the second telescopic hole 112 can be arranged on the surrounding frame 113 to further ensure the stability of the process of adjusting the uniformity of the gaps at the left and right ends of the air conditioner indoor unit 100 through the positioning structure 120, and the stability of the positioning and holding of the positioning structure 120 during the subsequent assembly of the air conditioner indoor unit 100 and the use of the air conditioner indoor unit 100.

[0083] Refer to Figure 1 、 Figure 2 and Figure 3 , in this embodiment, the positioning structure 120 further includes a first telescopic top plate 125 and a second telescopic top plate 126.

[0084] The first telescopic top plate 125 is arranged at the left end of the first telescopic rod 121, and the first telescopic top plate 125 is used for abutting against the left inner wall of the embedding cavity 210.

[0085] The second telescopic top plate 126 is arranged at the right end of the second telescopic rod 122, and the first telescopic top plate 125 is used for abutting against the right inner wall of the embedding cavity 210.

[0086] It can be understood that through the first telescopic top plate 125 and the second telescopic top plate 126, the contact area between the first telescopic rod 121 and the second telescopic rod 122 and the inner wall of the embedding cavity 210 can be increased. On the one hand, increasing the contact area between the first telescopic rod 121 and the second telescopic rod 122 and the inner wall of the embedding cavity 210 can reduce the pressure of the first telescopic rod 121 and the second telescopic rod 122 on the cabinet body 200, and effectively avoid the situation that the first telescopic rod 121 and the second telescopic rod 122 damage the inner wall surface of the embedding cavity 210. On the other hand, increasing the contact area between the first telescopic rod 121 and the second telescopic rod 122 and the inner wall of the embedding cavity 210 can increase the friction between the first telescopic rod 121 and the second telescopic rod 122 and the inner wall of the embedding cavity 210, so as to further ensure the stability of the process of adjusting the uniformity of the gaps at the left and right ends of the air conditioner indoor unit 100 through the positioning structure 120, and the stability of the positioning and holding of the positioning structure 120 during the subsequent assembly of the air conditioner indoor unit 100 and the use of the air conditioner indoor unit 100.

[0087] In addition, it can be understood that since the first telescopic top plate 125 and the second telescopic top plate 126 are in contact with the inner wall of the embedding cavity 210. If the first telescopic top plate 125 and the second telescopic top plate 126 are directly connected to the first telescopic rod 121 and the second telescopic rod 122 respectively, then during the process of adjusting the uniformity of the gaps at the left and right ends of the indoor unit 100 of the air conditioner, the first telescopic top plate 125 and the second telescopic top plate 126 will rotate along with the first telescopic rod 121 and the second telescopic rod 122. On the one hand, the contact between the first telescopic top plate 125 and the second telescopic top plate 126 and the inner wall of the embedding cavity 210 will limit the rotation of the first telescopic rod 121 and the second telescopic rod 122 around the axis. On the other hand, the first telescopic top plate 125 and the second telescopic top plate 126 will rub against the inner wall of the embedding cavity 210, damaging the cabinet body 200.

[0088] Furthermore, in the present embodiment, referring to Figure 1 , Figure 2 , Figure 3 and Figure 6 , the first telescopic top plate 125 is connected to the first telescopic rod 121 through the first hinge structure 127. The first hinge structure 127 is used to maintain the connection between the first telescopic top plate 125 and the first telescopic rod 121 while allowing the first telescopic rod 121 to rotate around the rotation axis. The second telescopic top plate 126 is connected to the second telescopic rod 122 through the second hinge structure 128. The second hinge structure 128 is used to maintain the connection between the second telescopic top plate 126 and the second telescopic rod 122 while allowing the second telescopic rod 122 to rotate around the rotation axis.

[0089] It can be understood that by connecting the first telescopic top plate 125 to the first telescopic rod 121 through the first hinge structure 127, and connecting the second telescopic top plate 126 to the second telescopic rod 122 through the second hinge structure 128, during the process of adjusting the uniformity of the gaps at the left and right ends of the indoor unit 100 of the air conditioner, the first telescopic top plate 125 and the second telescopic top plate 126 can be prevented from rotating along with the first telescopic rod 121 and the second telescopic rod 122 and rubbing against the inner wall of the embedding cavity 210. Furthermore, during the process of adjusting the uniformity of the gaps at the left and right ends of the indoor unit 100 of the air conditioner, the first telescopic top plate 125 and the second telescopic top plate 126 will not damage the cabinet body 200, ensuring the aesthetics of the cabinet body 200, and the contact between the first telescopic top plate 125 and the second telescopic top plate 126 and the inner wall of the embedding cavity 210 will not limit the rotation of the first telescopic rod 121 and the second telescopic rod 122.

[0090] Specifically, the first hinge structure 127 may include a hinge protrusion 1271 and a hinge seat 1272. The hinge seat 1272 is disposed on the first telescopic top plate 125, and a hinge cavity 1273 is provided inside the hinge seat 1272. A hinge groove 1274 is circumferentially formed on the inner wall of the hinge cavity 1273. The hinge protrusion 1271 is disposed on the outer periphery of the left end of the first telescopic rod 121. The left end of the first telescopic rod 121 is disposed inside the hinge cavity 1273, and the hinge protrusion 1271 is embedded in the hinge groove 1274. The second hinge structure 128 has the same structure as the first hinge structure 127. This enables the hinging of the first telescopic rod 121 and the first telescopic top plate 125, as well as the hinging of the second telescopic rod 122 and the second telescopic top plate 126.

[0091] In the second implementation manner of this embodiment, the first telescopic rod 121 and the second telescopic rod 122 may be telescopic rods of a cylinder. That is, the positioning structure 120 includes a first cylinder and a second cylinder respectively disposed inside the left and right ends of the housing 110.

[0092] The first telescopic rod 121 of the first cylinder passes through the first telescopic hole 111 and abuts against the left inner wall of the embedding cavity 210; the second telescopic rod 122 of the second cylinder passes through the second telescopic hole 112 and abuts against the right inner wall of the embedding cavity 210. Pneumatic adjustment is performed through the cylinders to adjust the telescopic amounts of the first telescopic rod 121 and the second telescopic rod 122. When no pneumatic adjustment instruction is issued to the cylinders / the pneumatic switch is not activated, the first telescopic rod 121 and the second telescopic rod 122 can maintain the distances between the left and right inner walls of the housing 110 and the embedding cavity 210.

[0093] Therefore, this implementation manner can also reduce the difficulty of adjusting the gaps at the left and right ends of the air conditioner indoor unit 100 to be uniform, and ensure the uniformity of the gaps at the left and right ends of the air conditioner indoor unit 100 during subsequent assembly and use, so as to ensure the aesthetics of the air conditioner indoor unit 100 when installed in the indoor space and ensure the user experience.

[0094] Refer to Figure 1 and Figure 4 In this embodiment, a heat exchange air inlet 115 is provided at the upper part of the front end of the housing 110, and a heat exchange air outlet 116 is provided at the lower part of the front end of the housing 110.

[0095] It can be understood that since both the heat exchange air inlet 115 and the heat exchange air outlet 116 are provided at the front end of the housing 110, the air conditioner indoor unit 100 of this embodiment can be embedded into the cabinet 200 while ensuring aesthetics and without affecting the performance of functions such as refrigeration / heating, ensuring aesthetics and the user experience.

[0096] Refer to Figure 1 and Figure 4, in this embodiment, the air conditioner indoor unit 100 further includes a wind guiding plate 130.

[0097] The first end of the wind guiding plate 130 is rotatably connected to the housing 110. The rotation axis of the wind guiding plate 130 is arranged in the left - right direction and is located between the heat exchange air inlet 115 and the heat exchange air outlet 116. The wind guiding plate 130 has a closed state in which the heat exchange air inlet 115 is closed and a wind guiding state in which the second end of the wind guiding plate 130 opposite to the first end is arranged forward and upward.

[0098] It can be understood that when the air conditioner indoor unit 100 is turned on and operates in cooling / heating and other modes, the second end of the wind guiding plate 130 is arranged forward and upward. At this time, the wind guiding plate 130 is in the wind guiding state. Further, the incoming air flow will enter the housing 110 from the heat exchange air inlet 115 from top to bottom, and the heat exchange air flow will flow out from the heat exchange air outlet 116. In this way, the wind guiding plate 130 separates the incoming air flow and the heat exchange air flow, effectively avoiding the mutual disturbance between the incoming air flow and the heat exchange air flow and affecting the working performance of the air conditioner indoor unit 100.

[0099] Moreover, the closed state of the wind guiding plate 130 avoids the situation that dust and other sundries enter the housing 110 from the heat exchange air inlet 115.

[0100] In addition, referring to Figure 4 , in this embodiment, the air conditioner indoor unit 100 further includes a driving link 140, and the driving link 140 is used to drive the wind guiding plate 130 to move and switch between the wind guiding state and the closed state.

[0101] Referring to Figure 7 , in this embodiment, the air conditioner indoor unit 100 further includes a volute 150, a heat exchange fan 160, and a heat exchange component 170 disposed in the housing 110.

[0102] The heat exchange fan 160 is disposed in the volute cavity of the volute 150, and the heat exchange component 170 is disposed on the volute 150 and is arranged in an inverted V - shape straddling above the heat exchange fan 160. Specifically, the heat exchange component 170 includes a first indoor heat exchanger 171, a second indoor heat exchanger 172, and a third indoor heat exchanger 173. The second indoor heat exchanger 172 is connected between the first indoor heat exchanger 171 and the third indoor heat exchanger 173. And the first indoor heat exchanger 171, the second indoor heat exchanger 172, and the third indoor heat exchanger 173 are arranged from front to back. The first indoor heat exchanger 171 is disposed in front of the heat exchange fan 160, the second indoor heat exchanger 172 is disposed in front - upper of the heat exchange fan 160, and the third indoor heat exchanger 173 is disposed in rear - upper of the heat exchange fan 160.

[0103] Moreover, a first air inlet duct 117 and a second air inlet duct 118 are provided inside the housing 110. The first air inlet duct 117 and the second air inlet duct 118 are separated by a partition plate 180. The front ends of the first air inlet duct 117 and the second air inlet duct 118 communicate with the heat exchange inlet. The first air inlet duct 117 is located in front of the first indoor heat exchanger 171 and the second indoor heat exchanger 172, and the first indoor heat exchanger 171 and the second indoor heat exchanger 172 are located at the tail end of the first air inlet duct 117; the tail end of the second air inlet duct 118 extends to the third indoor heat exchanger 173, and the tail end of the second air inlet duct 118 can extend to the rear of the third indoor heat exchanger 173.

[0104] It can be understood that since the heat exchange air inlet 115 is located in front of the housing 110, the air flow entering the housing 110 from the heat exchange air inlet 115 may not flow backward through the third indoor heat exchanger 173, but only flow through the first indoor heat exchanger 171 and the second indoor heat exchanger 172. In this way, the heat exchange amount of the heat exchange air flow is insufficient, and the refrigeration / heating effect becomes poor. At the same time, the heat exchange amount of the third indoor heat exchanger 173 is insufficient, and icing will occur when the indoor unit 100 of the air conditioner is in the refrigeration mode, or overheating will occur when the indoor unit 100 of the air conditioner is in the heating mode. Furthermore, by forming the first air inlet duct 117 and the second air inlet duct 118 through the partition plate 180, the second air inlet duct 118 can fully guide the air flow of the heat exchange air inlet 115 to the third indoor heat exchanger 173, effectively ensuring the heat exchange amount of the third indoor heat exchanger 173, ensuring the refrigeration / heating effect of the indoor unit 100 of the air conditioner, avoiding icing or overheating of the third indoor heat exchanger 173, and ensuring the stable operation of the indoor unit 100 of the air conditioner.

[0105] Refer to Figure 7 , in this embodiment, the second air inlet duct 118 is located above the first air inlet duct 117 to ensure the stability of the air flow in the first air inlet duct 117 and the second air inlet duct 118.

[0106] Refer to Figure 1 、 Figure 4 and Figure 7 , in this embodiment, the volute 150, the heat exchange fan 160, the heat exchange component 170, etc. are all arranged inside the surrounding frame 113, and the air guiding plate 130, the driving link 140, the heat exchange air inlet 115, and the heat exchange air outlet 116 are all arranged on the front cover 114.
