Technical Field

[0001] The utility model relates to the field of household appliances, in particular to an indoor unit of an air conditioner and an air conditioner. Background Art

[0002] There are many types of air conditioner indoor units. In order to better meet specific usage requirements, some air conditioner indoor units have air inlets set on the front surface of their shells instead of on the upper surface, so that the air conditioner indoor unit can take in air from the front. For example, for an embedded air conditioner indoor unit installed in a cabinet, since its upper side may be close to the top wall of the cabinet, the top air intake effect is poor, so the air inlet can be set on the front surface to take in air from the cabinet opening.

[0003] However, if the air inlet of the air conditioner indoor unit is set at the front side, even if the user does not use the air conditioner indoor unit, the air inlet is still exposed to the environment, which not only affects the aesthetics of the air conditioner indoor unit, but also easily causes dust to fall into the air inlet.

[0045] 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 schematic cross-sectional view of an indoor unit 20 of an air conditioner is shown.

[0046] refer to Figure 1 and Figure 2 As shown, this embodiment provides an air conditioner indoor unit 20 , and the air conditioner indoor unit 20 includes: a housing 21 , an air inlet baffle 22 and a push-pull device 30 .

[0047] An air inlet is provided on the front surface of the housing 21. An air inlet baffle 22 is disposed on the front side of the housing 21, and one side of the baffle 22 is rotatably connected to the housing 21; the air inlet baffle 22 is used to open and close the air inlet. A push-pull device 30 is disposed on the housing 21. The push-pull device 30 includes a fixed housing 31 fixed to the housing 21, and a transmission rod 32 movably disposed on the fixed housing 31. One end of the transmission rod 32 is connected to the air inlet baffle 22, thereby pushing or pulling the air inlet baffle 22 to rotate relative to the housing 21.

[0048] Figure 1 and Figure 2 The diagram shows the state of the air conditioner indoor unit 20 when the air inlet baffle 22 is in the position of opening the air inlet. The air inlet baffle 22 rotates around the rotation axis connected to the shell 21 and forms an inclined angle with the air inlet, so that the air conditioner indoor unit 20 can take in air from the air inlet along the angle direction.

[0049] The push-pull device 30 is disposed on the housing 21 and is used to drive the air inlet baffle 22 to move around its rotation axis, thereby opening or closing the air inlet. Figure 2 As shown, when the transmission rod 32 of the push-pull device 30 extends outward relative to the fixed housing 31, the air inlet baffle 22 can be pushed away from the air inlet and the air inlet can be opened. It can be understood that when the transmission rod 32 is retracted inward relative to the fixed housing 31, the air inlet baffle 22 can be pulled toward the air inlet and the air inlet can be closed. In addition to being used to push and pull the air inlet baffle 22, the transmission rod 32 also plays a role in fixing the air inlet baffle 22 at a specific position.

[0050] The air conditioner indoor unit 20 of this embodiment is provided with a transmission rod 32 to push or pull the air inlet baffle 22 to rotate, so that the air inlet baffle 22 can move away from or close to the housing 21 and open or close the air inlet. When the user does not use the air conditioner indoor unit 20, the air inlet is blocked by the air inlet baffle 22, which improves the aesthetics of the air conditioner indoor unit 20 on the one hand, and prevents dust from falling into the air conditioner indoor unit 20 from the air inlet on the other hand.

[0051] The push-pull device 30 of this embodiment can be arranged on the outside of the housing 21 of the air conditioner indoor unit 20, or on the inside of the housing 21, and can be arranged on the two lateral walls of the housing 21. The air conditioner indoor unit 20 of this embodiment can be provided with only one push-pull device 30 and arranged on one lateral wall of the housing 21 or in the lateral middle of the housing 21, or two push-pull devices 30 can be provided and respectively arranged on the two lateral walls of the housing 21. The two push-pull devices 30 working synchronously can effectively bear the weight of the left and right parts of the air inlet baffle 22, but the air conditioner indoor unit 20 of this embodiment can also be provided with three or more push-pull devices 30.

[0052] In some optional embodiments, a moving channel adapted to the shape of the transmission rod 32 is formed in the fixed housing 31, thereby limiting the movement of the transmission rod 32 along its own length direction in the moving channel.

[0053] refer to Figure 2 As shown, the transmission rod 32 of this embodiment only moves forward and backward along its own length direction under the restriction of the fixed shell 31, and the moving trajectory does not change in angle (the transmission rod 32 after movement deviates from the length direction of the transmission rod 32 when it is in the original position).

[0054] The moving channel defined by the fixed shell 31 can be defined by a continuous inner wall formed inside the fixed shell 31 itself, or can be defined by a plurality of spaced limiting columns located on opposite sides (eg, upper and lower sides) of the moving track of the transmission rod 32 .

[0055] In some optional embodiments, racks are formed on the transmission rod 32 and distributed along the length direction of the transmission rod 32.

[0056] The push-pull device 30 further includes a transmission gear 33 and a drive motor (not shown in the figure); the transmission gear 33 is engaged with the rack, so that it rotates under the drive of the drive motor and drives the transmission rod 32 to move.

[0057] refer to Figure 2 As shown, the transmission rod 32 of this embodiment is provided with racks along its length direction, and the racks are engaged with the transmission gear 33, so that when the transmission gear 33 rotates, the racks will move forward or backward accordingly and make the transmission rod 32 move synchronously. Figure 2The position of the driving motor is not shown in the figure. The driving motor can be a rotating shaft directly connected to the center of the transmission gear 33 to directly drive the transmission gear 33 to rotate, or it can be indirectly connected to the transmission gear 33 through transmission parts such as gears and transmit power to the transmission gear 33.

[0058] The rod body portion of the transmission rod 32 of this embodiment can be integrally formed with the rack portion, or can be formed as Figure 2 The rack can be formed on the surface of the transmission rod 32, or a recessed opening can be formed on one side of the transmission rod 32, and the rack is located inside the opening, and a part of the transmission gear 33 extends into the opening to engage with the rack.

[0059] Figure 3 It is a partially enlarged schematic diagram of an air conditioner indoor unit 20 according to an embodiment of the utility model.

[0060] refer to Figure 3 As shown, in some optional embodiments, a clamping joint 322 is formed at the end of the transmission rod 32 connected to the air inlet baffle 22, and a clamping groove 222 is provided on the air inlet baffle 22. The setting position and shape of the clamping groove 222 are adapted to the moving track of the clamping joint 322, so that the clamping joint 322 is movably connected to the clamping groove 222.

[0061] The movable connection means that the card connector 322 can move in the card slot 222, but can maintain the connection state with the card slot 222 without separation. Figure 2 As shown, since the clamping joint 322 is located at the end of the transmission rod 32, it moves in a straight line with the transmission rod 32, and the clamping groove 222 set on the air inlet baffle 22 moves around the rotation axis of the air inlet baffle 22. Therefore, during the opening and closing process of the air inlet baffle 22, the clamping joint 322 will move in the clamping groove 222, and the direction of movement is in the diameter direction of the rotation axis of the air inlet baffle 22.

[0062] Therefore, the clamping groove 222 of the present embodiment is in the shape of an elongated strip, and the extending direction is parallel to the diameter direction of the rotation axis of the air inlet baffle 22 , so that the clamping joint 322 can move in the clamping groove 222 .

[0063] Figure 4 yes Figure 1 A schematic cross-sectional view of the engaging groove 222 of the indoor unit 20 of the air conditioner is shown.

[0064] In some optional embodiments, the clamping groove 222 includes two spaced apart clamping walls, each of which has a clamping section 222B close to the air inlet baffle 22; the cross section of the clamping groove 222 along a direction perpendicular to its length is partially circular between the two clamping sections 222B. And the surface of the clamping joint 322 connected to the clamping groove 222 is partially spherical.

[0065] refer to Figure 3 and Figure 4 As shown, the left and right clamping walls of the clamping slot 222 each have a clamping section 222B, and the shape of the clamping section 222B is usually bilaterally symmetrical. Figure 4 What is actually shown is a cross-sectional view of the clamping groove 222 along a direction perpendicular to its length. Figure 4 It can be seen that the interval between the two engaging sections 222B forms a partial circle with an opening.

[0066] At the same time, reference Figure 3 As shown, the present embodiment further provides a clamping joint 322 whose surface is a partial sphere and connected to the clamping groove 222. Since the surface of the upper part of the clamping joint 322 in contact with the clamping groove 222 is a spherical surface, the contact area between the clamping joint 322 and the clamping groove 222 can be increased. In addition, in the process of the transmission rod 32 pushing and pulling the air inlet baffle 22, the angle formed by the transmission rod 32 and the air inlet baffle 22 will change. In the present embodiment, by providing the clamping joint 322 whose surface is a partial sphere, the clamping joint 322 will rotate in the clamping groove 222 and the contact area remains unchanged in the process of the transmission rod 32 pushing and pulling the air inlet baffle 22, thereby ensuring that the pulling force of the transmission rod 32 is evenly and effectively transmitted to the air inlet baffle 22 and the clamping joint 322 evenly bears the weight of the air inlet baffle 22.

[0067] In some optional embodiments, the material of the clamping slot 222 is an elastic material, so that the clamping joint 322 can be detachably connected to the clamping slot 222 .

[0068] The card slot 222 of this embodiment has Figure 4 The schematic shape causes the two clamping walls to be elastically deformed respectively, thereby increasing the opening size or restoring the elasticity of the shape, so that the card connector 322 can be inserted inward or pulled outward, so as to facilitate the user to disassemble and install the air inlet baffle 22.

[0069] In order to facilitate the insertion of the snap joint 322 into the snap groove 222, in some optional embodiments, the two clamping walls also respectively have an opening section 222C extending from the end of the snap groove 222 away from the air inlet baffle 22 and with a gradually increasing interval width.

[0070] The end opening size of the opening section 222C is larger than the diameter of the clamping joint 322 , so that the user can make the clamping joint 322 face the clamping groove 222 when the user cannot observe the position of the clamping joint 322 in advance, thereby reducing the difficulty of installing the air inlet baffle 22 .

[0071] In some optional embodiments, the clamping slot 222 further has a base section 222A connecting the two clamping walls. The base section 222A, the clamping section 222B and the opening section 222C are integrally formed, and the surface of the base section 222A of the clamping slot 222 is in contact with the surface of the air inlet baffle 22, so as to facilitate the fixing of the clamping slot 222 and the air inlet baffle 22.

[0072] The snap-fitting groove 222 may be fixed on the surface of the air inlet baffle 22 by screw connection, bonding, etc., or may be fixed in a groove by forming a groove of an adaptable shape on the air inlet baffle 22 .

[0073] Figure 5 yes Figure 1 Another schematic cross-sectional view of the air conditioner indoor unit 20 is shown.

[0074] In some optional embodiments, the air inlet is opened at the upper portion of the front surface of the housing 21 ; and the lower side of the air inlet baffle 22 is rotatably connected to the housing 21 .

[0075] refer to Figure 5 As shown, the air inlet of the air conditioner indoor unit 20 of this embodiment is opened at the upper part of the front surface of the housing 21, and the lower side of the air inlet baffle 22 is rotatably connected to the housing 21, so that the opening direction of the air inlet is toward the upper front of the air conditioner indoor unit 20. The air outlet of the air conditioner indoor unit 20 is usually toward the lower front, and the air inlet baffle 22 of this embodiment can effectively prevent the airflow blown from the air outlet from being directly sucked into the air inlet again.

[0076] In some optional embodiments, an air outlet is further provided at the lower portion of the front surface of the housing 21. The air conditioner indoor unit 20 further includes a first air guide plate. The first air guide plate is disposed at the air outlet and has a rotation axis that is close to the upper side of the air outlet and extends laterally.

[0077] refer to Figure 5 As shown, in some optional embodiments, an air inlet is opened at the upper portion of the front surface of the shell 21 , and an air outlet is opened at the lower portion of the front surface of the shell 21 .

[0078] 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. Different from the traditional wall-mounted air conditioner indoor unit 20, the embedded air conditioner indoor unit 20 is embedded in the cabinet, so that the air conditioner indoor unit 20 is hidden in appearance, making the home layout more beautiful.

[0079] In order to adapt to the opening of the cabinet, the air conditioner indoor unit 20 of this embodiment is provided with an air inlet on the upper part of the front surface of the shell 21, and the air outlet is provided on the lower part of the front surface of the shell 21. That is to say, the front surface of the shell 21 is provided with an air inlet and an air outlet at the same time, that is, the air inlet and outlet of the air conditioner indoor unit 20 are located on the same side and correspond to the opening position of the cabinet, so that the air conditioner indoor unit 20 can take in and out air from the front at the same time.

[0080] Figure 5 The diagram shows a position of the first air guide plate 26 when it is in the open state. The first air guide plate 26 of this embodiment is turned upward around the rotation axis near the upper side of the air outlet, and uses its own plate body to separate the air inlet from the air outlet. Therefore, when the first air guide plate 26 of this embodiment is opened, it can not only guide the outlet air flow by adjusting the rotation height and change the air outlet distance, but also separate the air inlet and the air 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.

[0081] In some optional embodiments, one end of the first air guide plate 26 away from the rotation axis is bent toward the air outlet.

[0082] Figure 5 The arrows indicate the direction of airflow at the air outlet. The first air guide plate 26 of this embodiment is bent toward the air outlet at one end away from the rotation axis, thereby forming a concave arc surface. When the first air guide plate 26 is opened and the air conditioner indoor unit 20 is discharging air, the airflow direction at the air outlet is guided to tilt downward along the arc surface.

[0083] 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 26 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 26, so it also has a certain effect on preventing the airflow blown from the air outlet from being directly sucked into the air inlet again.

[0084] The first air guide plate 26 of this embodiment can be formed by bending the entire plate body and forming an arc shape as a whole, or it can be formed by bending the entire plate body and forming an arc shape as a whole. Figure 5 Schematically, only the surface of the first air guide plate 26 facing the air outlet is bent, while the other side is a straight surface adapted to the shape of the air outlet.

[0085] The air conditioner indoor unit 20 of this embodiment may also generally include an air supply fan 23, an air supply duct 25 and a heat exchanger 24. Figure 5 As shown, the air supply fan 23 is arranged in the housing 21, and is used to promote the formation of an air flow that enters the air conditioner indoor unit 20 from the air inlet and blows out from the air outlet. The heat exchanger 24 is arranged in the housing 21 and is located between the air inlet and the air supply fan 23, and is used to exchange heat with the air flow that enters the air conditioner indoor unit 20 from the air inlet. One end of the air supply duct 25 is connected to the air outlet, and the other end is connected to the air supply fan 23, so as to guide the air flow formed by the air supply fan 23 to blow toward the air outlet.

[0086] In some optional implementations, the air conditioner indoor unit 20 further includes: a second air guide plate 27 and a third air guide plate group.

[0087] The second air guide plate 27 is disposed in the air supply duct 25 and has a rotation axis extending transversely near the lower surface of the air supply duct 25, and is used to guide the air outlet direction of the air conditioner indoor unit 20. The third air guide plate group is disposed in the air supply duct 25 and includes a plurality of third air guide plates 28 distributed in the transverse direction; each third air guide plate 28 has a rotation axis extending longitudinally, and is used to guide the air outlet direction of the air conditioner indoor unit 20.

[0088] refer to Figure 4 As shown, the air supply duct 25 of this embodiment is connected to the air outlet at one end and to the air supply fan 23 at the other end, so as to guide the air flow formed by the air supply fan 23 to blow toward the air outlet. The first air guide plate 26 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 25. The second air guide plate 27 is arranged close to the lower surface of the air supply duct 25, and the two ends of its rotating shaft can also be connected to the two lateral walls of the air supply duct 25.

[0089] The second air guide plate 27 can swing upward from a position close to the lower surface of the air supply duct 25, 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 27 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 23. For example, when the speed of the air supply fan 23 remains unchanged, when the swing height of the second air guide plate 27 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 23 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 27, 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.

[0090] Figure 4 Only one third air guide plate 28 in the third air guide plate group can be seen, but it can be understood that multiple third air guide plates 28 of this embodiment are arranged side by side in the air supply duct 25. In some optional embodiments, multiple third air guide plates 28 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.

[0091] exist Figure 4 In the illustrated embodiment, the third air guide plate group is disposed on the lower surface of the air supply duct 25 , while in other optional implementations, the third air guide plate group may also be disposed on the upper surface of the air supply duct 25 .

[0092] Figure 6 1 is a schematic diagram of an air conditioner 10 according to an embodiment of the present invention.

[0093] The air conditioner 10 of this embodiment includes an air conditioner indoor unit 20, and also includes an air conditioner outdoor unit 10, and a refrigerant pipeline connecting the two. The compressor, condenser, and throttling device in the air conditioner outdoor unit 10 are connected to the evaporator in the air conditioner indoor unit 20 through the refrigerant pipeline, and together with other necessary components, constitute the refrigeration cycle system of the air conditioner 10.
