Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0028] 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 those of ordinary skill in the art can implement them. When the combination of the technical solutions is contradictory or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the protection scope required by the present invention.

[0029] The present invention provides an indoor air conditioner, which specifically relates to a wall-mounted indoor air conditioner. The indoor air conditioner can be a single-cooling machine or a heating and cooling machine. The following mainly describes the indoor air conditioner with both a refrigeration mode and a heating mode.

[0030] In the embodiment of the present invention, as Figure 1 and Figure 2 shown, the indoor air conditioner includes: a housing 10, provided with an air outlet 11, and the housing 10 includes a bottom plate 12 disposed below the air outlet 11; a wind deflector, installed at the air outlet 11; a driving device, installed inside the housing 10; a connecting rod 30, one end of the connecting rod 30 is connected to the wind deflector, and the other end is connected to the driving shaft of the driving device; a first protrusion 31 is provided on the part of the connecting rod 30 facing the bottom plate 12, and / or a second protrusion is provided on the part of the bottom plate 12 facing the connecting rod 30, so that when the connecting rod 30 drives the wind deflector to open the air outlet 11, the bottom plate 12 and the connecting rod 30 are in point contact through the first protrusion 31 and / or the second protrusion.

[0031] In this embodiment, the housing 10 is used to form the overall appearance of the air conditioner indoor unit. The housing 10 includes a chassis, a front frame and a panel. An air inlet is provided on the housing 10. The air inlet can be provided at the top of the housing 10. A wind channel is formed inside the housing 10. A heat exchanger assembly, a blower, etc. are also provided inside the housing 10. External 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 blower. 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, as long as it satisfies that the air outlet 11 is communicated with the wind channel so that the air in the wind channel can be blown out from the air outlet 11. The air deflector extends along the length direction of the housing 10 to block the air outlet 11.

[0032] The connecting rod 30 is arranged at the air outlet 11. The driving shaft of the driving device is selected to drive the connecting rod 30 to rotate, thereby driving the air deflector to move, so that the air deflector opens or closes the air outlet 11. The number of the connecting rods 30 can be one, or two or more. In practical applications, the number of the connecting rods 30 can be two and are respectively arranged at both ends in the length direction of the housing 10 to make the support for the air deflector 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 deflector closes the air outlet 11, the lower side edge of the air deflector can abut against the front side edge of the bottom plate 12. When the connecting rod 30 rotates to abut against the bottom plate 12, the air deflector completely opens the air outlet 11. At this time, under the limiting action of the bottom plate 12, the connecting rod 30 cannot continue to rotate. It is fed back to the controller through the sensor, and the controller then controls the driving device to stop running, so that the connecting rod 30 keeps abutting against the bottom plate 12.

[0033] The specific shape of the first protrusion 31 is not limited, as long as it satisfies point contact or line contact with the bottom plate 12. The specific shape of the second protrusion corresponds to that of the first protrusion 31 and will not be elaborated here. By abutting the first protrusion 31 against the bottom plate 12, the contact area between the first protrusion 31 and the bottom plate 12 can be reduced, so that during the process of the connecting rod 30 abutting against the bottom plate 12 or during the operation of the air conditioner indoor unit, the noise generated by the relative vibration friction between the connecting rod 30 and the bottom plate 12 is reduced, so as to improve the user experience.

[0034] In the air conditioner indoor unit of the present invention, by providing the first protrusion 31 and / or the second protrusion at the abutting position of the connecting rod 30 and the bottom plate 12, the connecting rod 30 and the bottom 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 bottom plate 12, reducing the noise generated by the mutual vibration friction between the connecting rod 30 and the bottom plate 12, improving the user experience and enhancing the practicality of the air conditioner indoor unit.

[0035] It should be noted that if there are directional indications (such as up, down, left, right, front, back...) involved in the embodiments of the present invention, the directional indications are only used to explain the relative positional relationship, movement conditions, etc. between components in a certain specific posture (as shown in the drawings). If the specific posture changes, the directional indications will also change accordingly.

[0036] In addition, if there are descriptions such as "first", "second", etc. involved in the embodiments of the present invention, the descriptions of "first", "second", etc. are only for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly specifying the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include at least one such feature. In addition, the meaning of "and / or" appearing throughout the text is that it includes three parallel solutions. Taking "A and / or B" as an example, it includes solution A, or solution B, or a solution where A and B are satisfied simultaneously.

[0037] In one embodiment, as Figure 2 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 edge of the plate body 121 and is connected through 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 deflector fully opens the air outlet 11, the first protrusion 31 abuts against the folded edge 122. Under the pressure of the connecting rod 30, the folded edge 122 can deform towards the buffer gap 123 to reduce the sound generated during the compression process. In addition, during the operation of the air conditioner indoor unit, the buffer gap 123 can also provide a deformation space for the vibration of the folded edge 122 to further reduce the relative friction with the connecting rod 30, so as to further reduce the generation of noise.

[0038] Specifically, as Figure 2 shown, one 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 a direction inclined upward away from the air outlet 11. Thus, it can prevent 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 and further improving the practicality of the air conditioner indoor unit.

[0039] In practical applications, the air conditioner indoor unit further includes a heat preservation member disposed in the buffer gap 123. In this embodiment, during the operation of the air conditioner indoor unit, air flow will blow into the buffer gap 123, which will not only reduce the air output volume, but also cause the generation of condensed water due to the temperature difference between the inner and outer sides of the connecting plate. The heat preservation strip is integrally strip-shaped. Setting a heat preservation member in the buffer gap 123 can prevent air flow from blowing into the buffer gap 123. Thus, it can not only ensure the air output volume, but also avoid the generation of condensed water. The thickness, height, and length of the heat preservation member can be selected and designed according to actual needs, and no specific limitation is made here. The heat preservation member can be installed between the panel and the front water receiving tray by means of glue bonding, embedding, clamping, etc. The heat preservation member can be one or a combination of a sponge strip, a foam strip, or a flannel strip. The sponge strip, the foam strip, and the flannel strip have good heat preservation effects and low prices, so the cost is low. At the same time, when the heat preservation member is set as a sponge strip or a flannel strip, it can also play a role in absorbing water, so as to prevent condensed water from flowing out. The water absorbed by the sponge strip and the flannel strip can be naturally dried by air flow.

[0040] In one embodiment, the portion of the first protrusion 31 abutting against the bottom plate 12 is arranged in an arc shape. In this embodiment, the portion of the first protrusion 31 abutting against the bottom plate 12 is arranged in an arc shape and is smoothly transitioned with other portions. Thus, the touching process between the first protrusion 31 and the bottom plate 12 can be made more gentle, and the connection strength between the first protrusion 31 and the connecting rod 30 is higher, avoiding breakage of the first protrusion 31 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. The buffer layer can be made of rubber material or cotton wadding 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 vibration, thereby further reducing the noise of the air conditioner indoor unit.

[0041] In practical applications, as Figure 2 shown, the connecting rod 30 is bent, the housing 10 and the air deflector are respectively connected to two ends of the connecting rod 30, and the portion of the connecting rod 30 adjacent to the bent portion 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 movement range of the air deflector to improve the stability of the air deflector movement. The bent connecting rod 30 has a recessed portion, and the first protrusion 31 protrudes from a position adjacent to the bent portion of the recessed portion, which can reduce the proportion of the connecting rod 30 outside the abutting portion, thereby reducing the pressure on the bottom plate 12 to avoid damage to the bottom plate 12 and improving the stability of the air conditioner indoor unit.

[0042] In one embodiment, as Figure 2As shown, in the state where the air deflector 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 bent portion 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 recessed portion of the connecting rod 30. The clearance gap 13 enables the connecting rod 30 to rotate to abut against the plate surface of the bottom plate 12, so that the air deflector can move to fully open the air outlet 11, avoiding obstruction of the movement of the connecting rod 30 by the bottom plate 12 and making the movement process of the air deflector smoother.

[0043] Specifically, the width of the clearance gap 13 does not exceed 6 mm and is not less than 4 mm. In this embodiment, the width of the clearance gap 13 is the distance between the bent portion of the connecting rod 30 and the front side of the bottom plate 12. If the width of the clearance gap 13 is less than 4 mm, the bottom plate 12 will provide insufficient clearance for the connecting rod 30, resulting in relative vibration and friction between the bent portion and the front side of the bottom plate 12, generating noise. If the width of the clearance gap 13 exceeds 6 mm, the proportion of the connecting rod 30 outside the abutting portion will be too large, causing excessive pressure on the bottom plate 12 and easily damaging the bottom plate 12. Therefore, setting the width of the clearance gap 13 to 4 mm to 6 mm can not only reduce the generation of noise but also improve the stability of the bottom plate 12.

[0044] 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, which can not only improve the connection strength between the first protrusion and the connecting rod but also reduce the processing procedures and improve production efficiency.

[0045] The present invention also provides an air conditioner, which includes an outdoor unit and an indoor unit of the air conditioner. The specific structure of the indoor unit of the air conditioner refers to the above embodiments.

Any equivalent structural transformation made by using the description and drawings of the present invention under the inventive concept of the present invention, or direct / indirect application in other related technical fields, is included in the patent protection scope of the present invention.
