[0037] Figure 1 is a schematic diagram of an air conditioner indoor unit 20 according to an embodiment of the utility model; Figure 2 yes Figure 1 A partial enlarged schematic diagram of the A portion of the air conditioner indoor unit 20 is shown; Figure 3 yes Figure 1 Another schematic diagram of the air conditioner indoor unit 20 is shown; Figure 4 yes Figure 3 The diagram is a partial enlarged schematic diagram of part B of the indoor unit 20 of the air conditioner.

[0038] The present embodiment provides an air conditioner indoor unit 20, and the air conditioner indoor unit 20 includes: a shell 21 and a positioning device 40. At least one outer surface of the shell 21 is a fixed surface that is attached to the assembly surface; the assembly surface provides support or fixation for the air conditioner indoor unit 20. The positioning device 40 is arranged on the fixing surface, and includes a positioning member 41 that can at least partially extend out of the fixing surface, or is completely hidden in the fixing surface. The positioning device 40 is used to make the positioning member 41 extend out of the fixing surface and snap into the concave hole on the assembly surface when the air conditioner indoor unit 20 is moved to a preset installation position, so that the air conditioner indoor unit 20 is fixed relative to the assembly surface.

[0039] exist Figure 1 and Figure 3 In the illustrated embodiment, the mounting surface is the bottom surface of the cabinet 60 . Figure 1 and Figure 3 The air conditioner indoor unit 20 is shown in the state of being in the preset installation position and not being in the preset installation position respectively, and Figure 2 and Figure 4 The working states of the positioning device 40 in corresponding states are respectively enlarged and illustrated.

[0040] refer to Figure 3 and Figure 4 As shown, the positioning member 41 can be hidden in the fixing surface, so as not to affect the movement of the air conditioner indoor unit 20 on the assembly surface. When the air conditioner indoor unit 20 moves to the preset installation position, the positioning member 41 can extend and snap into the concave hole reserved on the assembly surface, thereby preventing the air conditioner indoor unit 20 from moving further.

[0041] In some optional embodiments, the positioning member 41 can be as follows Figure 2 and Figure 4 The figure shows a round bead, and a hemispherical concave hole adapted to the shape of the part of the positioning member 41 that can extend out of the fixing surface is opened on the assembly surface of the cabinet 60. Therefore, when the positioning device 40 moves with the air conditioner indoor unit 20 to the top of the concave hole on the assembly surface, the positioning member 41 can extend and snap into the concave hole, thereby increasing the resistance to the continued movement of the air conditioner indoor unit 20.

[0042] The positioning member 41 usually makes a sound when it is inserted into the concave hole. When the user or installer pushes the air conditioner indoor unit 20 into the cabinet 60, as long as the sound is heard and the movement resistance of the air conditioner indoor unit 20 is increased, it can be known that the air conditioner indoor unit 20 has reached the preset installation position. In addition, the moment the positioning member 41 is inserted into the concave hole, the air conditioner indoor unit 20 is prevented from continuing to move and the air conditioner indoor unit 20 is prevented from continuing to slide into the cabinet 60 under the action of inertia. After the positioning member 41 is inserted into the concave hole, the positioning device 40 can also prevent the air conditioner from moving due to accidental contact or collision.

[0043] It should be noted that the preset installation position of the air conditioner indoor unit 20 on the assembly surface can be set according to actual conditions. Since the position of the positioning device 40 on the shell 21 is fixed, the preset installation position can also be adjusted accordingly according to the installation effect that the user hopes to achieve, and the recessed hole on the assembly surface is adaptively adjusted according to the preset installation position. For example, if the cabinet 60 needs to reserve space for installing the door body, the preset installation position is relatively closer to the inside of the cabinet 60, so that the recessed hole on the assembly surface can also be opened closer to the inside. If the user wants to set the air conditioner indoor unit 20 against the opening edge of the cabinet 60, then the preset installation position is relatively closer to the outside of the cabinet 60, so that the recessed hole on the assembly surface can also be opened closer to the inside.

[0044] The recessed hole on the assembly surface can be artificially opened, but the recessed hole can also be omitted when installing the air conditioner indoor unit 20. The recessed hole can be formed by the fixing surface of the air conditioner indoor unit 20 being in contact with the assembly surface and being deformed by the positioning part 41 for a long time.

[0045] The air conditioner indoor unit 20 of this embodiment can be an embedded air conditioner indoor unit 20, that is, the air conditioner indoor unit 20 is embedded in the cabinet 60. Different from the traditional wall-mounted air conditioner indoor unit 20, the embedded air conditioner indoor unit 20 is embedded in the cabinet 60, so that the air conditioner indoor unit 20 is hidden in appearance, making the home layout more beautiful.

[0046] However, the air conditioner indoor unit 20 of this embodiment may not be embedded in the cabinet 60, for example, it may be directly placed on the top surface of the cabinet 60, on a desktop or other flat surface. In this case, the assembly surface is correspondingly provided by the top surface of the cabinet 60, the desktop or other flat surface, and the bottom surface of the shell 21 can be used as a fixed surface supported by the assembly surface.

[0047] In some optional embodiments, the positioning member 41 may also be a cylinder or a prism, and the entire member or only the portion extending outside the fixing surface may be in the shape of a cylinder or a prism.

[0048] In some optional embodiments, the positioning member 41 is made of metal material, for example, various metal or alloy materials such as steel and copper, and the positioning member 41 made of metal material is stronger and more wear-resistant. In some optional embodiments, the positioning member 41 can be a metal ball. Since the metal ball can roll in any direction, when the air conditioner indoor unit 20 is pushed along the assembly surface of the cabinet 60, the friction between the assembly surface and the air conditioner indoor unit 20 is smaller, and the resistance when pushing the air conditioner indoor unit 20 will not be increased, and the assembly surface of the cabinet 60 will not be worn.

[0049] In addition, in the embodiment where the positioning member 41 is a round bead, when the air conditioner indoor unit 20 needs to be taken out from the cabinet 60, only the air conditioner indoor unit 20 needs to be pulled by applying force, and the positioning member 41 can be pushed from the edge of the concave hole. Figure 2 The state shown is moved up and hidden in the fixed surface. Figure 4 As shown, it is convenient to take out the air conditioner indoor unit 20. In the embodiment where the positioning member 41 is a cylinder or a prism, if the air conditioner indoor unit 20 needs to be taken out from the cabinet 60, the air conditioner indoor unit 20 needs to be lifted up first so that the positioning member 41 is raised to be out of the concave hole, and it is relatively difficult to take out the air conditioner indoor unit 20.

[0050] The fixing surface of the air conditioner indoor unit 20 of this embodiment may include the top surface, the bottom surface and the outer surface of at least one side wall of the housing 21. Figure 1 In the embodiment shown, the fixing surface includes the bottom surface of the housing 21, so the positioning member 41 needs to move downward to extend out of the fixing surface. The positioning device 40 of this embodiment may not include an elastic member, and the positioning member 41 is configured to extend out of the fixing surface under the action of gravity.

[0051] In some optional embodiments, the positioning device 40 further includes an elastic member 42. The elastic member 42 is disposed on a side of the positioning member 41 away from the fixing surface and abuts against the positioning member 41 to force the positioning member 41 to extend out of the fixing surface.

[0052] The elastic member 42 is used to push the positioning member 41, but it is obvious that the thrust that the elastic member 42 can provide is smaller than the gravity of the air conditioner indoor unit 20. Therefore, the positioning member 41 of the positioning device 40 installed on the fixed surface of the bottom surface of the shell 21 will not push the positioning member 41 out of the fixed surface during the process of pushing the air conditioner indoor unit 20 into the cabinet 60. Instead, the positioning member 41 will be pressed and hidden in the fixed surface due to the inability to overcome the gravity of the air conditioner indoor unit 20. Therefore, the positioning device 40 will not affect the movement of the air conditioner indoor unit 20 during the process of pushing the air conditioner indoor unit 20 into the cabinet 60.

[0053] However, when the air conditioner indoor unit 20 is moved to the preset installation position, the positioning member 41 will pop out and at least partially extend out of the fixing surface under the push of the elastic member 42, and be stuck into the recessed hole on the assembly surface, thereby fixing the air conditioner indoor unit 20.

[0054] The elastic member 42 may generally be a spring, but may also be other parts capable of providing elastic force.

[0055] In the embodiment where the positioning device 40 includes the elastic member 42, the fixing surface may not be limited to the bottom surface of the housing 21, that is, it may also include the top surface of the housing 21 and the outer surface of at least one lateral side wall. However, it is understood that the positioning device 40 disposed on the fixing surface of the bottom surface of the housing 21 may also include the elastic member 42.

[0056] If a positioning device 40 is provided on the top surface of the shell 21 of the air conditioner indoor unit 20, and when the air conditioner indoor unit 20 is installed, the top surface of the shell 21 is in contact with the top surface of the cabinet 60, then the top surface of the shell 21 can also be used as a fixing surface, and the top surface of the cabinet 60 can be used as an assembly surface to provide fixation for the air conditioner indoor unit 20.

[0057] Similarly, if a positioning device 40 is provided on the outer surface of one lateral side wall or two side walls of the shell 21 of the air conditioner indoor unit 20, and when the air conditioner indoor unit 20 is installed, the outer surface of one lateral side wall or two side walls of the shell 21 is in contact with the side surface of the cabinet 60, then the outer surface of one lateral side wall or two side walls of the shell 21 can also be used as a fixing surface, and the side surface of the cabinet 60 can be used as an assembly surface to provide fixation for the air conditioner indoor unit 20.

[0058] The indoor unit 20 of the air conditioner of this embodiment may have multiple fixing surfaces at the same time, and each fixing surface may be provided with one or more positioning devices 40. According to different positions of the fixing surfaces, the structures of the positioning devices 40 on different fixing surfaces may be different, for example, the positioning device 40 on the fixing surface of the bottom surface of the housing 21 may not include the elastic member 42.

[0059] In some optional implementations, the positioning device 40 further includes: a baffle 43 .

[0060] The baffle 43 is disposed on the fixing surface and is provided with a through hole for limiting a portion of the positioning member 41 from extending out of the fixing surface.

[0061] refer to Figure 2 As shown, the baffle 43 is used to prevent the positioning member 41 from falling out completely or being pushed out of the fixing surface by the elastic member 42, and when the positioning member 41 is a round ball, the baffle 43 also serves to limit the size of the positioning member 41 extending out of the fixing surface.

[0062] In some optional implementations, the positioning device 40 further includes a fixing screw 44. The fixing screw 44 is used to fix the baffle 43 on the fixing surface.

[0063] In order to prevent the baffle 43 from wearing the assembly surface when the air conditioner indoor unit 20 is pushed into the cabinet 60, in some optional embodiments, the outer surface of the baffle 43 and the fixing surface are located in the same plane.

[0064] The outer surface of the baffle 43 may also be embedded in the fixed surface of the housing 21, that is, the baffle 43 is recessed into the surface of the housing 21, so that a gap is generated between the outer surface of the baffle 43 and the fixed surface of the housing 21. However, in this embodiment, a positioning member 41 with a sufficiently long extension length is required to improve the fixing effect of the positioning device 40 on the indoor unit 20 of the air conditioner.

[0065] Meanwhile, in the embodiment where the positioning device 40 further includes a fixing screw 44 , the outer end of the fixing screw 44 may be hidden in the outer surface of the baffle 43 .

[0066] The air conditioner indoor unit 20 of this embodiment can be an embedded air conditioner indoor unit 20, that is, the air conditioner indoor unit 20 is embedded in the cabinet 60. Different from the traditional wall-mounted air conditioner indoor unit 20, the embedded air conditioner indoor unit 20 is embedded in the cabinet 60, so that the air conditioner indoor unit 20 is hidden in appearance, making the home layout more beautiful.

[0067] refer to Figure 1As shown, in order to adapt to the opening of the cabinet 60, the air conditioner indoor unit 20 of this embodiment is provided with an air inlet at the upper part of the front surface of the housing 21, and an air outlet at the lower part of the front surface. That is to say, the front surface of the housing 21 is provided with an air inlet and an air outlet at the same time, that is, the air inlet and the air outlet of the air conditioner indoor unit 20 are located on the same side and correspond to the opening position of the cabinet 60, so that the air conditioner indoor unit 20 takes in and out air from the front side at the same time.

[0068] refer to Figure 1 As shown, in some optional embodiments, the air conditioner indoor unit 20 further includes a first air guide plate 31. The first air guide plate 31 has a fixed end close to the upper side of the air outlet and rotatably connected to the housing 21 or the front surface of the housing 21, and a rotating end away from the fixed end. The surface of the first air guide plate 31 is bent toward the air outlet at the rotating end.

[0069] Figure 1 The figure shows a position of the first air guide plate 31 when it is in the open state. The first air guide plate 31 of this embodiment is turned upward around the rotation axis of its fixed end, and uses its own plate body to separate the air inlet from the air outlet. Therefore, when the first air guide plate 31 of this embodiment is opened, it can not only guide the outlet air flow by adjusting the rotation height and change the outlet distance, but also separate the air inlet and outlet on its upper and lower sides, so as to prevent the air inlet from directly sucking the heat exchange air flow blown out from the air outlet back into the air conditioner indoor unit 20, thereby optimizing the air inlet and outlet effects of the air conditioner indoor unit 20 and improving the heat exchange efficiency and air supply effect.

[0070] Figure 1 Arrows are also used to indicate the direction of the airflow at the air outlet under the guidance of the first air guide plate 31. The first air guide plate 31 of this embodiment is bent toward the air outlet at the rotation end away from its rotation axis, so that the surface forms a concave arc surface. When the first air guide plate 31 is opened and the air conditioner indoor unit 20 is discharging air, the direction of the airflow at the air outlet is guided to tilt downward along the arc surface.

[0071] Since the air outlet of the embedded air conditioner indoor unit 20 is located at the front side thereof, the shape of the first air guide plate 31 of the present embodiment can ensure that the airflow can be blown obliquely downward when the opening of the air outlet is large, so as to avoid the situation where the air supply height of the air conditioner indoor unit 20 is too high and cannot meet the direct blowing requirements of some users. In addition, the airflow blown from the air outlet tends to flow away from the air inlet side due to the guidance of the first air guide plate 31, so it also has a certain effect in preventing the airflow blown from the air outlet from being directly sucked into the air inlet again.

[0072] In some optional embodiments, a plurality of air inlet grilles 22 extending laterally are formed on the front surface of the shell 21 at the air inlet; and each air inlet grille 22 is inclined downward toward the air conditioner indoor unit 20, thereby guiding the airflow to enter the air conditioner indoor unit 20 from the air inlet in a downward inclined direction.

[0073] Figure 1 Arrows are also used to indicate the direction of air flow at the air inlet. Figure 1 As shown, the front surface of the shell 21 of this embodiment forms a plurality of transversely extending air inlet grilles 22 at the air inlet, and the air inlet grilles 22 are parallel and juxtaposed in the longitudinal direction, so that an air inlet gap extending obliquely downward toward the interior of the air conditioner indoor unit 20 is formed between two adjacent air inlet grilles 22 in the longitudinal direction, and the air flow enters the air conditioner indoor unit 20 from the air inlet in a downward oblique direction.

[0074] The air inlet grille 22 at the air inlet can be a continuous line or a plurality of spaced segments in the horizontal direction.

[0075] As Figure 3 As indicated by the middle arrow, the air inlet grille 22 of the present embodiment guides the airflow at the air inlet to tend to enter the air inlet obliquely downward from the upper side, thereby having a certain effect on preventing the airflow at the air inlet from forming convection with the air flow at the air outlet and the airflow blown out of the air outlet from being directly sucked into the air inlet again.

[0076] In some optional embodiments, the air inlet and the air outlet on the front surface of the shell 21 are spaced apart in height, so that there is a certain distance between the lower end of the air inlet and the air outlet and the first air guide plate 31 when in the open state, thereby further separating the air inlet and the air outlet, preventing the airflow blown out of the air outlet from being directly sucked into the air inlet again, and reducing the convection between the airflow at the air inlet and the air outlet.

[0077] The reason why condensation is easily formed at the air guide plate of the indoor unit 20 of the air conditioner is that the air guide plate has a lower temperature under the influence of the heat exchange airflow. When it contacts the ambient air with a higher temperature, it is easy to cause the moisture in the ambient air to condense on the air guide plate and form condensation. When the airflow at the air inlet forms convection with the airflow at the air outlet, the upper surface of the first air guide plate 31 in the open state will contact more moisture in the ambient air with the airflow at the air inlet and condensation is more likely to occur.

[0078] Therefore, the utility model sets the rotating end of the first air guide plate 31 to be bent toward the air outlet, each air inlet grille 22 is tilted downward toward the air conditioner indoor unit 20, or the air inlet and the air outlet on the front surface of the shell 21 are spaced in height, so that the airflow at the air inlet and the air outlet are separated in the flow direction, thereby reducing the convection between the airflow at the air inlet and the air outlet, so as to reduce or even avoid the formation of condensation on the surface of the first air guide plate 31.

[0079] In some optional embodiments, the air conditioner indoor unit 20 can simultaneously be configured such that the rotating end of the first air guide plate 31 is bent toward the air outlet, each air inlet grille 22 is inclined downward toward the air conditioner indoor unit 20, and the air inlet and the air outlet on the front surface of the shell 21 are spaced in height, so as to maximize the anti-condensation effect of the air guide plate of the air conditioner indoor unit 20.

[0080] In some optional implementations, the air conditioner indoor unit 20 further includes: an air supply duct 30 and a second air guide plate 32 .

[0081] The air supply duct 30 is disposed in the housing 21 , and one end of the air supply duct 30 is connected to the air outlet.

[0082] The second air guide plate 32 is disposed in the air supply duct 30 and has a rotation axis close to the lower surface of the air supply duct 30 and extending laterally, and is used to guide the air outlet direction of the air conditioner indoor unit 20.

[0083] refer to Figure 1 As shown, the air supply duct 30 of this embodiment is connected to the air outlet at one end and to the air supply fan at the other end, so as to guide the air flow formed by the air supply fan to blow toward the air outlet. The first air guide plate 31 is arranged at the air outlet, and the two ends of its rotating shaft are connected to the two lateral walls of the air supply duct 30. The second air guide plate 32 is arranged close to the lower surface of the air supply duct 30, and the two ends of its rotating shaft can also be connected to the two lateral walls of the air supply duct 30.

[0084] The second air guide plate 32 can swing upward from a position close to the lower surface of the air supply duct 30, so as to adjust the air outlet height of the air conditioner indoor unit 20. When the swing height of the second air guide plate 32 is high, the size of the air outlet can also be reduced, so as to change the distance of the air outlet and the perceived wind speed in accordance with the speed change of the air supply fan. For example, when the speed of the air supply fan remains unchanged, when the swing height of the second air guide plate 32 is high and the air outlet is reduced, the actual air outlet speed of the air conditioner indoor unit 20 becomes faster due to the reduction of the air outlet. When the speed of the air supply fan decreases, the actual air outlet speed of the air conditioner indoor unit 20 can be maintained stable by reducing the size of the air outlet by swinging the second air guide plate 32, so as to reduce the air supply volume of the air conditioner indoor unit 20 when the perceived wind speed remains basically unchanged, so as to adjust the ambient temperature.

[0085] In some optional embodiments, the air conditioner indoor unit 20 further includes a third air guide plate group.

[0086] The third air guide plate group is arranged in the air supply duct 30 and includes a plurality of third air guide plates 33 distributed in the transverse direction; each third air guide plate 33 has a longitudinally extending rotation axis for guiding the air outlet direction of the air conditioner indoor unit 20.

[0087] Figure 1 Only one third air guide plate 33 in the third air guide plate group can be seen, but it can be understood that multiple third air guide plates 33 of this embodiment are arranged side by side in the air supply duct 30. In some optional embodiments, multiple third air guide plates 33 in the third air guide plate group can be synchronously controlled to rotate and adjust the lateral air outlet direction of the air conditioner indoor unit 20.

[0088] exist Figure 3 In the illustrated embodiment, the third air guide plate group is disposed on the lower surface of the air supply duct 30 , while in other optional implementations, the third air guide plate group may also be disposed on the upper surface of the air supply duct 30 .

[0089] In some optional implementations, the air conditioner indoor unit 20 further includes: an air supply fan 24 , a heat exchanger 25 , and an air inlet baffle 26 .

[0090] The air supply fan 24 is disposed in the housing 21 to facilitate the formation of an air flow that enters the air conditioner indoor unit 20 from the air inlet and is blown out from the air outlet.

[0091] The heat exchanger 25 is disposed in the housing 21 and is located between the air inlet and the air supply fan 24, and is used for exchanging heat with the air flow entering the air conditioner indoor unit 20 from the air inlet.

[0092] The air inlet baffle 26 is horizontally arranged in the housing 21, with one end close to the air inlet and the other end close to the heat exchanger 25, so as to separate the air flow entering the air conditioner indoor unit 20 from the air inlet into two upper and lower parts.

[0093] refer to Figure 1 As shown, in order to improve the heat exchange efficiency, the air conditioner indoor unit 20 of this embodiment has a heat exchanger 25 arranged on the upper peripheral side of the air supply fan 24, wherein part of the heat exchanger 25 is close to and faces the air inlet of the air conditioner indoor unit 20, while another part of the heat exchanger 25 is away from the air outlet due to being bent backward and downward.

[0094] In order to prevent the incoming air flow from only passing through the front half of the heat exchanger 25 near the air inlet, causing the rear half of the heat exchanger 25 to not participate in or participate less in heat exchange, an air inlet baffle 26 is particularly arranged in the shell 21, with one end of the air inlet baffle 26 close to the air inlet and the other end close to the heat exchanger 25, thereby dividing the airflow entering the air conditioner indoor unit 20 from the air inlet into two parts, an upper part and a lower part.

[0095] The air conditioner indoor unit 20 of this embodiment utilizes the spacing of the air inlet baffle 26 to allow the air flow entering the air conditioner indoor unit 20 from the lower air inlet to pass through the front half heat exchanger 25, while also ensuring that the air flow entering the air conditioner indoor unit 20 from the upper air inlet can flow to and pass through the rear half heat exchanger 25, thereby making full use of the heat exchanger 25 and avoiding the accumulation of cold energy.

[0096] In this embodiment, a gap is formed between the upper end of the heat exchanger 25 and the upper part of the shell 21 to allow air flow to pass through, and the end of the air inlet baffle 26 can be close to the upper end of the heat exchanger 25, thereby dividing the heat exchanger 25 into two parts, front and back, and ensuring that the air flow entering from the air inlet of the upper half is guided to the rear half of the heat exchanger 25.

[0097] In the embodiment where an air inlet grille 22 is formed at the air inlet on the front surface of the housing 21 , an end of the air inlet partition plate 26 may abut against one of the air inlet grilles 22 .

[0098] In some embodiments of the present application, the air inlet baffle 26 may not be horizontally arranged in the housing 21, that is, it may be inclined or bent, and the airflow entering the air conditioner indoor unit 20 from the air inlet is also divided into upper and lower parts. However, the above embodiment may affect the normal flow of the airflow and cause the air intake efficiency of the air conditioner indoor unit 20 to decrease, and therefore it is generally not the most preferred embodiment.

[0099] In some optional embodiments, the heat exchanger 25 may also be Figure 3 The illustrated embodiment is arranged on the upper peripheral side of the air supply fan 24, for example, it can be arranged in the shell 21 longitudinally or in other ways, and the air inlet baffle 26 can also be correspondingly arranged with its end located in the middle of the height of the heat exchanger 25, thereby dividing the heat exchanger 25 into two upper and lower parts opposite to the air inlet.
