[0028] The realization of the purpose, functional features and advantages of the present invention will be further explained in conjunction with embodiments and with reference to the accompanying drawings. DETAILED DESCRIPTION

[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0030] It should be noted that the technical solutions between the various embodiments can be combined with each other, but it must be based on the fact that ordinary technicians in the field can implement it. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0031] The present invention provides an air conditioner indoor unit, which specifically relates to a wall-mounted air conditioner indoor unit. The air conditioner indoor unit can be a cooling unit or a cooling and heating unit. The following mainly describes an air conditioner indoor unit having both a cooling mode and a heating mode.

[0032] In the embodiment of the present invention, Figure 1 and Figure 2 As shown, the air-conditioning indoor unit includes: a shell 10, which is provided with an air outlet 11, and the shell 10 includes a bottom plate 12 arranged below the air outlet 11; an air guide plate installed on the air outlet 11; a driving device installed in the shell 10; a connecting rod 30, one end of which is connected to the air guide plate, and the other end is connected to the driving shaft of the driving device; the part of the connecting rod 30 facing the bottom plate 12 is provided with a first protrusion 31, and / or the part of the bottom plate 12 facing the connecting rod 30 is provided with a second protrusion, so that when the connecting rod 30 drives the air guide plate to open the air outlet 11, the bottom plate 12 contacts the connecting rod 30 through the first protrusion 31 and / or the second protrusion point.

[0033] In this embodiment, the housing 10 is used to form the overall appearance of the indoor unit of the air conditioner. The housing 10 includes a chassis, a face frame and a panel. The housing 10 is provided with an air inlet, which can be provided at the top of the housing 10. An air duct is formed inside the housing 10. The housing 10 is also provided with a heat exchanger assembly and a fan. The outside air enters the housing 10 from the air inlet, and after the heat exchange of the heat exchanger, it is blown out through the air outlet 11 under the action of the fan. The position of the air outlet 11 is not limited. For example, the air outlet 11 is provided on the front panel of the housing 10. It is only necessary that the air outlet 11 is connected to the air duct so that the wind in the air duct can be blown out from the air outlet 11. The air guide plate extends along the length direction of the housing 10 to block the air outlet 11.

[0034] The connecting rod 30 is arranged at the air outlet 11. The driving shaft of the driving device can drive the connecting rod 30 to rotate, thereby driving the air guide plate to move, so that the air guide plate opens or closes the air outlet 11. The number of connecting rods 30 can be one, or two or more. In practical applications, the number of connecting rods 30 can be two and they are arranged at both ends of the length direction of the shell 10 to make the support of the air guide plate more stable. The bottom plate 12 is connected to the bottom of the air outlet 11. The bottom plate 12 is arranged at intervals along the length direction of the air outlet 11. When the air guide plate closes the air outlet 11, the lower side of the air guide plate can abut against the front side of the bottom plate 12. When the connecting rod 30 rotates to abut against the bottom plate 12, the air guide plate completely opens the air outlet 11. At this time, the connecting rod 30 cannot continue to rotate under the limiting effect of the bottom plate 12, and is fed back to the controller through the sensor. The controller then controls the driving device to stop running, so that the connecting rod 30 remains abutting against the bottom plate 12.

[0035] The specific shape of the first protrusion 31 is not limited, and it only needs to meet the point contact or line contact with the bottom plate 12. The specific shape of the second protrusion corresponds to the first protrusion 31, and will not be repeated here. By the first protrusion 31 abutting against the bottom plate 12, the contact area between the first protrusion 31 and the bottom plate 12 can be reduced, so that when the connecting rod 30 abuts against the bottom plate 12, or when the air conditioner indoor unit is running, the noise generated by the relative vibration and friction between the connecting rod 30 and the bottom plate 12 is reduced, so as to improve the user experience.

[0036] The air conditioning indoor unit of the present invention is provided with a first protrusion 31 and / or a second protrusion at the abutment between the connecting rod 30 and the base plate 12, so that the connecting rod 30 and the base plate 12 can achieve point contact through the first protrusion 31 and / or the second protrusion, thereby reducing the contact area between the connecting rod 30 and the base plate 12, thereby reducing the noise generated by the mutual vibration and friction between the connecting rod 30 and the base plate 12, thereby improving the user experience and enhancing the practicality of the air conditioning indoor unit.

[0037] It should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back, etc.), the directional indications are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0038] In addition, if there are descriptions involving "first", "second", etc. in the embodiments of the present invention, the descriptions of "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or suggesting their relative importance or implicitly indicating the number of technical features indicated. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In addition, the meaning of "and / or" appearing in the full text is to include three parallel solutions, taking "A and / or B as an example", including solution A, or solution B, or a solution that satisfies both A and B.

[0039] In one embodiment, if Figure 2 As shown, the bottom plate 12 includes a plate body 121 and a folded edge 122 connected to the plate body 121, the first protrusion 31 abuts against the folded edge 122, and a buffer gap 123 is formed between the folded edge 122 and the plate body 121. In this embodiment, the folded edge 122 is connected to the front side of the plate body 121 and is connected by a connecting plate. The folded edge 122 is opposite to the plate body 121, and a buffer gap 123 is formed between the folded edge 122 and the plate body 121. When the air guide plate fully opens the air outlet 11, the first protrusion 31 abuts against the folded edge 122, and under the pressure of the connecting rod 30, the folded edge 122 can be deformed toward the buffer gap 123 to reduce the sound generated during the pressure process. In addition, during the operation of the air conditioner indoor unit, the buffer gap 123 can also provide deformation space for the vibration of the folded edge 122, further reducing the relative friction with the connecting rod 30, so as to further reduce the generation of noise.

[0040] Specifically, Figure 2 As shown, the end of the folded edge 122 away from the air outlet 11 is upturned. In this embodiment, the folded edge 122 extends from the side connected to the plate body 121 in an obliquely upward direction away from the air outlet 11, thereby preventing the free end of the folded edge 122 from deforming to touch the plate body 121, thereby preventing the folded edge 122 from colliding with the plate body 121 to generate noise, further improving the practicality of the air conditioner indoor unit.

[0041] In practical applications, the air conditioner indoor unit further includes a heat preservation member arranged in the buffer gap 123. In this embodiment, during the operation of the air conditioner indoor unit, the air flow will blow into the buffer gap 123, which will not only reduce the air volume, but also cause condensation water to be generated due to the temperature difference between the inside and outside of the connecting plate. The heat preservation strip is arranged in a strip shape as a whole, and the heat preservation member is arranged in the buffer gap 123, which can prevent the air flow from blowing into the buffer gap 123, thereby ensuring the air volume and avoiding the generation of condensation water. The thickness, height and length of the heat preservation member can be selected and designed according to actual needs, and are not specifically limited here. The heat preservation member can be installed between the panel and the front water tray by means of glue bonding, embedding, clamping, etc. The heat preservation member can be one of a sponge strip, a foam strip or a flannel strip or a combination thereof. The sponge strip, the foam strip and the flannel strip have good heat preservation effect and are cheap, so the cost is low. At the same time, the heat preservation member is arranged as a sponge strip or a flannel strip, which can also play a role in absorbing water, thereby preventing condensation water from flowing out. The water absorbed by the sponge strips and flannel strips can be dried naturally through air flow.

[0042] In one embodiment, the portion where the first protrusion 31 abuts against the bottom plate 12 is provided in an arc surface. In this embodiment, the portion where the first protrusion 31 abuts against the bottom plate 12 is provided in an arc surface, and is in a smooth transition with other portions, thereby making the contact process between the first protrusion 31 and the bottom plate 12 more gentle, and the connection strength between the first protrusion 31 and the connecting rod 30 higher, avoiding the first protrusion 31 from breaking, so as to improve the stability of the connecting rod 30. Specifically, a buffer layer is provided on the surface of the first protrusion 31 and / or the second protrusion, and the buffer layer can be a rubber material or a cotton material, as long as it has an elastic buffering effect. The buffer layer can further reduce the relative friction between the connecting rod 30 and the bottom plate 12 during the vibration process, thereby further reducing the noise of the air conditioner indoor unit.

[0043] In practical applications, such as Figure 2 As shown, the connecting rod 30 is bent, the housing 10 and the air guide plate are respectively connected to the two ends of the connecting rod 30, and the portion of the connecting rod 30 adjacent to the bend abuts against the bottom plate 12. In this embodiment, the connecting rod 30 is arranged in a plate shape bent along one side, which can improve the structural strength of the connecting rod 30 and reduce the range of motion of the air guide plate to improve the stability of the air guide plate. The bent connecting rod 30 has a recessed portion, and the first protrusion 31 is convexly arranged at the position of the recessed portion adjacent to the bend, which can reduce the proportion of the connecting rod 30 outside the abutment, thereby reducing the pressure on the bottom plate 12 to avoid damage to the bottom plate 12 and improve the stability of the air conditioner indoor unit.

[0044] In one embodiment, if Figure 2As shown, when the air guide plate opens the air outlet 11, a clearance gap 13 is formed between the edge of the bottom plate 12 adjacent to the air outlet 11 and the bending part of the connecting rod 30. In this embodiment, the clearance gap 13 is formed between the front side of the bottom plate 12 and the bottom of the concave part of the connecting rod 30. The clearance gap 13 allows the connecting rod 30 to rotate to abut against the plate surface of the bottom plate 12, so that the air guide plate can move to fully open the air outlet 11, avoiding the bottom plate 12 from hindering the movement of the connecting rod 30, so that the movement process of the air guide plate is smoother.

[0045] Specifically, the width of the avoidance gap 13 does not exceed 6mm and is not less than 4mm. In this embodiment, the width of the avoidance gap 13 is the distance between the bending part of the connecting rod 30 and the front side of the bottom plate 12. If the width of the avoidance gap 13 is less than 4mm, the bottom plate 12 will not avoid the connecting rod 30 enough, resulting in the bending part vibrating and rubbing against the front side of the bottom plate 12 to generate noise; if the width of the avoidance gap 13 exceeds 6mm, the proportion of the connecting rod 30 outside the abutment part will be too large, resulting in excessive pressure on the bottom plate 12, which is easy to cause damage to the bottom plate 12; therefore, setting the width of the avoidance gap 13 to 4mm to 6mm can reduce the generation of noise and improve the stability of the bottom plate 12.

[0046] In practical applications, the first protrusion and the connecting rod are integrally formed, that is, the first protrusion and the connecting rod can be integrally injection molded, thereby improving the connection strength between the first protrusion and the connecting rod, reducing the processing steps, and improving production efficiency.

[0047] The present invention also provides an air conditioner, which includes an air conditioner outdoor unit and an air conditioner indoor unit. The specific structure of the air conditioner indoor unit refers to the above embodiment. Since the air conditioner adopts all the technical solutions of all the above embodiments, it at least has all the beneficial effects brought by the technical solutions of the above embodiments, which will not be described one by one here. Among them, the air conditioner indoor unit and the air conditioner outdoor unit are connected by a refrigerant pipe.

[0048] The above description is only a preferred embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the inventive concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
