Description

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 casing rather than 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, an air inlet baffle needs to be set at the air inlet to improve the aesthetics of the air conditioner indoor unit and prevent dust from falling into the air inlet. However, the existing air inlet baffle is difficult to open manually, which will hinder users from cleaning the air inlet. Utility Model Content

[0047] 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 the air conditioner indoor unit 20 is shown.

[0048] 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 casing 21 , an air inlet baffle 22 and a push-pull device 30 .

[0049] 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 is rotatably disposed at the air inlet for opening and closing the air inlet. A push-pull device 30 is disposed on the housing 21 and has a movable end that can move forward and backward relative to the housing 21. The push-pull device 30 includes a magnetic connector 31 disposed at the movable end, and the magnetic connector 31 is magnetically connected to the air inlet baffle 22, so that the air inlet baffle 22 opens and closes the air inlet under the drive of the push-pull device 30 and is detachably disposed from the push-pull device 30.

[0050] 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 casing 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.

[0051] The push-pull device 30 is disposed on the housing 21 and drives the air inlet baffle 22 to move around its rotation axis by moving its moving end forward and backward, thereby opening or closing the air inlet. Figure 2 As shown, when the transmission rod 33 of the push-pull device 30 extends outward relative to the fixed housing 32, 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 33 is retracted inward relative to the fixed housing 32, 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 33 also plays a role in keeping the air inlet baffle 22 at a specific position.

[0052] It can be understood that the forward and backward movement of the mobile terminal described in this embodiment is not limited to the forward and backward movement in the horizontal direction, but can also be the oblique forward movement with a height change, that is, the movement to the upper side of the front or the lower side of the front. In other words, the forward and backward movement of the mobile terminal described in this embodiment only means that the mobile terminal moves away from or close to the air inlet in the forward and backward direction.

[0053] The air conditioner indoor unit 20 of this embodiment is provided with a push-pull device 30 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.

[0054] In addition, the air conditioner indoor unit 20 of this embodiment is provided with a magnetic connector 31 at the mobile end, so that the push-pull device 30 is magnetically connected to the air inlet baffle 22, and the air inlet baffle 22 is detachably arranged relative to the push-pull device 30, so that the air inlet baffle 22 can be opened manually. As long as the user applies force to the air inlet baffle 22 in the direction of opening the air inlet, the air inlet baffle 22 can overcome the magnetic attraction of the magnetic connector 31 and separate from the magnetic connector 31, so that it can be freely opened to a larger angle. When the user needs to restore the air inlet baffle 22 to its original position, he only needs to push the air inlet baffle 22 back in the direction of closing the air inlet, and the air inlet baffle 22 will be magnetically connected by the magnetic connector 31 again.

[0055] The magnetic connecting member 31 can usually be a permanent magnet, or an electromagnet if the production cost is not taken into consideration.

[0056] The push-pull device 30 of this embodiment can be arranged on the outside of the casing 21 of the air conditioner indoor unit 20, or on the inside of the casing 21, and can be arranged on the two lateral walls of the casing 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 casing 21 or in the lateral middle of the casing 21, or two push-pull devices 30 can be provided and respectively arranged on the two lateral walls of the casing 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 in some optional embodiments, the air conditioner indoor unit 20 can also be provided with three or more push-pull devices 30.

[0057] In some optional embodiments, the push-pull device 30 further includes: a fixed shell 32 and a transmission rod 33 .

[0058] The fixed housing 32 is fixed on the housing 21. The transmission rod 33 is movably arranged on the fixed housing 32, and enables the moving end located at the front end thereof to move forward and backward relative to the housing 21.

[0059] refer to Figure 2 As shown, the push-pull device 30 of this embodiment includes a fixed shell 32 and a transmission rod 33. The movable end of the push-pull device 30 is located at the front end of the transmission rod 33. Therefore, by driving the front end of the transmission rod 33 to move forward and backward, the air inlet baffle 22 can be driven to move.

[0060] In some optional embodiments, a moving channel adapted to the shape of the transmission rod 33 is formed in the fixed housing 32 , thereby limiting the transmission rod 33 from moving along its length in the moving channel. An opening of the moving channel faces the front side of the housing 21 .

[0061] refer to Figure 2 As shown, the transmission rod 33 of this embodiment only moves forward and backward along its own length direction under the restriction of the fixed shell 32, and the moving trajectory does not change in angle (the transmission rod 33 after movement deviates from the length direction of the transmission rod 33 when it is in the original position).

[0062] The moving channel defined by the fixed shell 32 can be defined by a continuous inner wall formed inside the fixed shell 32 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 33 .

[0063] The moving channel formed in the push-pull device 30 of this embodiment can be inclined relative to the horizontal plane, so that the angle between the transmission rod 33 and the air inlet baffle 22 is closer to a right angle when the air inlet is opened, so that the push-pull device 30 can better provide support for the air inlet baffle 22.

[0064] The push-pull device 30 of this embodiment only includes a transmission rod 33 that moves along the moving channel. In some optional embodiments, the push-pull device 30 may also have other structures and may include multiple connecting rods. For example, the push-pull device 30 may include a V-shaped or X-shaped transmission structure composed of multiple connecting rods, or a parallelogram transmission structure, etc., which are not listed one by one here.

[0065] In some optional embodiments, a rack structure distributed along the length direction of the transmission rod 33 is formed on the transmission rod 33.

[0066] The push-pull device 30 further includes a transmission gear 34 and a drive motor (not shown). The transmission gear 34 is engaged with the rack structure on the transmission rod 33, so that it rotates under the drive of the drive motor and drives the transmission rod 33 to move.

[0067] refer to Figure 2As shown, the transmission rod 33 of this embodiment is provided with a rack structure along its length direction, and the rack is engaged with the transmission gear 34, so that when the transmission gear 34 rotates, the rack will move forward or backward accordingly and make the transmission rod 33 move synchronously. The position of the driving motor is not shown in the figure, and the driving motor can be a rotating shaft directly connected to the center of the transmission gear 34 to directly drive the transmission gear 34 to rotate, or it can be indirectly connected to the transmission gear 34 through transmission parts such as gears and transmits the transmission gear 34.

[0068] The rod body of the transmission rod 33 of this embodiment can be integrally formed with the rack part, or can be separately provided and assembled and fixed as shown in the figure. The rack can be formed on the surface of the transmission rod 33, or a recessed opening can be formed on one side of the transmission rod 33, and the rack is located inside the opening, and a part of the transmission gear 34 extends into the opening to engage with the rack.

[0069] In addition to providing a transmission gear 34 and a rack structure to drive the transmission rod 33 to move, the air conditioner indoor unit 20 of this embodiment may also be provided with an electric push rod, the fixed part of which is fixed to the housing 21 of the air conditioner indoor unit 20, serving as the fixed housing 32 of the push-pull device 30, and the movable rod body of the electric push rod serves as the transmission rod 33, the end of which is connected to the magnetic connector 31 and drives the air inlet baffle 22 to open and close the air inlet. It can be understood that the push-pull device 30 of the air conditioner indoor unit 20 of this embodiment may also include other types of transmission rods 33, which are not listed here one by one.

[0070] Figure 3 It is a partially enlarged schematic diagram of an air conditioner indoor unit 20 according to an embodiment of the utility model;

[0071] refer to Figure 3 As shown, in some optional embodiments, the magnetic connector 31 forms a smooth plane on the side close to the air inlet baffle 22. And the magnetic connector 31 is rotatably connected to the moving end of the push-pull device 30.

[0072] In the air conditioner indoor unit 20 of the present embodiment, since the magnetic connector 31 is located at the end of the transmission rod 33, it moves in a straight line with the transmission rod 33. During the rotation of the air inlet baffle 22, the angle between the transmission rod 33 and the air inlet baffle 22 will continue to change, and the contact position between the air inlet baffle 22 and the moving end will also move, and the direction of movement is in the diameter direction of the rotation axis of the air inlet baffle 22.

[0073] Therefore, in order to ensure the stability of the magnetic attraction between the magnetic connector 31 and the air inlet baffle 22, the present embodiment forms a smooth plane on the side of the magnetic connector 31 close to the air inlet baffle 22 to facilitate the sliding of the magnetic connector 31 relative to the air inlet baffle 22, and on the other hand, the magnetic connector 31 is rotatably connected to the movable end of the push-pull device 30, so that when the air inlet baffle 22 is opened to any angle, the plane of the magnetic connector 31 is tightly fitted with the air inlet baffle 22, and the magnetic attraction will not be weakened due to the reduction in contact area.

[0074] In other optional embodiments, the magnetic connector 31 can also be fixedly connected to the movable end of the push-pull device 30, and the magnetic connector 31 forms an arc surface on the side close to the air inlet baffle 22, so that the magnetic connector 31 is in contact with the air inlet baffle 22 when the air inlet baffle 22 is opened to any angle.

[0075] In some optional embodiments, the plate body of the air inlet baffle 22 may be made of metal, specifically iron (including steel and various iron alloys), and can be magnetically connected to the magnetic connector 31. The air inlet baffle 22 may form two spaced protrusions at positions corresponding to the magnetic connector 31 to limit the magnetic connector 31 from sliding between the gaps between the two protrusions.

[0076] In order to reduce the weight of the air inlet baffle 22 and reduce the production cost of the air inlet baffle 22, in some optional embodiments, the air inlet baffle 22 is provided with a metal adsorption member 35 at a position corresponding to the magnetic connection member 31, so as to be magnetically connected to the magnetic connection member 31. The plate body of the air inlet baffle 22 of this embodiment can be an integrally formed injection molding material, and the metal adsorption member 35 is fixed on the surface of the air inlet baffle 22 and is magnetically connected to the magnetic connection member 31.

[0077] The metal adsorption member 35 may be fixed on the surface of the air inlet baffle plate 22 by screw connection, bonding, etc., or may be fixed in a slot by forming a slot with an adapted shape on the air inlet baffle plate 22 .

[0078] In some optional implementations, the metal adsorption component 35 includes: a bottom plate 351 and two limiting plates 352 .

[0079] The bottom plate 351 is attached to the air inlet baffle 22 and provides a smooth surface attached to the magnetic connector 31. Two limit plates 352 extend from both sides of the bottom plate 351 toward the push-pull device 30, and the shape of the gap between the two limit plates 352 is consistent with the sliding track of the magnetic connector 31 on the metal adsorption member 35.

[0080] refer to Figure 3As shown, one side of the bottom plate 351 of the metal adsorbent 35 of this embodiment is in contact with the air inlet baffle 22, and the other side is a smooth surface and in contact with the magnetic connector 31. The bottom plate 351 of the metal adsorbent 35 and the surface of the magnetic connector 31 close to the air inlet baffle 22 are both smooth planes, so the sliding resistance of the magnetic connector 31 on the metal adsorbent 35 can be reduced, so that the push-pull device 30 can smoothly drive the air inlet baffle 22 to rotate and open.

[0081] The metal adsorption component 35 also includes two spaced limit plates 352, and the shape of the gap between the two limit plates 352 is consistent with the sliding trajectory of the magnetic connector 31 on the metal adsorption component 35, thereby clamping the magnetic connector 31 in the middle, which not only increases the fitting area between the magnetic connector 31 and the metal adsorption component 35, thereby enhancing the magnetic attraction, but also limits the moving trajectory of the magnetic connector 31, preventing the magnetic connector 31 from deviating from the moving trajectory and preventing the transmission rod 33 of the push-pull device 30 from being skewed.

[0082] Figure 4 yes Figure 1 Another schematic cross-sectional view of the air conditioner indoor unit 20 is shown;

[0083] 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 .

[0084] refer to Figure 4 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 casing 21, and the lower side of the air inlet baffle 22 is rotatably connected to the casing 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.

[0085] 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 26. The first air guide plate 26 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.

[0086] refer to Figure 4 As shown, the air inlet of the indoor unit 20 of the air conditioner of this embodiment is opened at the upper part of the front surface of the casing 21, and the air outlet is opened at the lower part of the front surface of the casing 21.

[0087] 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.

[0088] 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 casing 21, and an air outlet is provided on the lower part of the front surface of the casing 21. That is to say, the front surface of the casing 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.

[0089] Figure 4 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.

[0090] In some optional embodiments, one end of the first air guide plate 26 away from the rotation axis is bent toward the air outlet.

[0091] Figure 4 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.

[0092] 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.

[0093] The first air guide plate 26 of this embodiment can be bent as a whole and have an arc shape as a whole, or as shown in the figure, only the surface of the first air guide plate 26 facing the air outlet is bent, while the other side is a flat surface and adapts to the shape of the air outlet.

[0094] 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. As shown in the reference figure, 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. The air supply duct 25 is connected to the air outlet at one end and connected 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 be blown to the air outlet.

[0095] 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.

[0096] 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.

[0097] 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.

[0098] 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.

[0099] 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.

[0100] 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 .
