The outlet 101 of the indoor unit of the air conditioner is generally provided with a louver assembly 110, and the outlet air of the outlet 101 is guided by the louver assembly 110. However, the louver assembly 110 also blocks the outlet air of the outlet 101 to some extent, which results in a reduction in the cooling or heating speed of the air conditioner.

As shown in fig. 1-7, the present disclosure provides an indoor unit including a cabinet 100, a sliding rail assembly 120, and a louver assembly 110. Wherein, the casing 100 is provided with an air outlet 101; the sliding rail assembly 120 is disposed in the casing 100, and a part of the sliding rail assembly 120 corresponds to the air outlet 101; the louver assembly 110 is disposed in the casing 100, and the louver assembly 110 is slidably connected to the sliding rail assembly 120; the louver assembly 110 slides along the sliding rail assembly 120 to shield the air outlet 101 or avoid the air outlet 101, so as to adjust or avoid the air outlet of the air outlet 101.

By adopting the indoor unit provided by the embodiment of the disclosure, under the condition that the louver assembly 110 slides to the air outlet 101 along the slide rail assembly 120 to shield the air outlet 101, the air outlet of the air outlet 101 can be adjusted through the louver assembly 110; under the condition that tripe subassembly 110 slides to dodging air outlet 101 along slide rail set 120, the air-out of air outlet 101 did not receive any hindrance this moment, made the air output the biggest quick refrigeration of realization or heat fast.

In some embodiments, the louver assembly 110 has at least a shielding position and a storage position, and the louver assembly 110 completely shields the air outlet 101 of the casing 100 when in the shielding position, as shown in fig. 1; when the louver assembly 110 is located at the storage position, it completely avoids the air outlet 101, as shown in fig. 3.

Optionally, the indoor unit has an adjusting outlet mode and a maximum outlet mode. When the indoor unit operates in the air outlet adjusting mode, the louver assembly 110 is located at the shielding position, and the air outlet of the air outlet 101 is adjusted through the louver assembly 110 in the air outlet adjusting mode; when the indoor unit operates in the maximum air outlet mode, the louver assembly 110 is located at the storage position, and the air outlet 101 is not shielded in the mode, so that the maximum air outlet quantity can be realized.

Alternatively, as shown in FIG. 2, the louver assembly 110 includes a grid plate 111 and louvers 112. The grating plate 111 is matched with the air outlet 101 so as to completely shield the air outlet 101; one or more louvers 112 are movably disposed on a side of the grating 111 away from the air outlet 101 for guiding the wind direction; wherein, the grid plate 111 is slidably connected to the sliding rail assembly 120. Thus, the grating plates 111 can slide along the sliding rail assemblies 120, and the louvers 112 disposed on the grating plates 111 move synchronously. Because grid plate 111 and air outlet 101 looks adaptation, when grid plate 111 slided to air outlet 101 along sliding rail set 120, can shelter from air outlet 101 completely. After the grille plate 111 completely blocks the air outlet 101, the louvers 112 are movable to effectively guide the air blown from the inside of the cabinet 100 to the outside of the cabinet 100 through the grille plate 111.

Alternatively, the air outlet 101 is configured as a rectangular opening with a vertically opened length direction, and the grating plate 111 is configured as a rectangular plate adapted to the air outlet 101. A louver 112 is disposed on a side of the grating plate 111 away from the outlet 101. Alternatively, the louvers 112 are uniformly disposed on the side of the grating plate 111 away from the air outlet 101 along the length direction of the grating plate 111, and the louvers 112 can guide the air outlet of the air outlet 101 when moving synchronously.

Alternatively, as shown in fig. 4, the slide rail assembly 120 includes a slide rail 121 and a slide 122. Wherein the slide rail 121 is configured as a linear or curved rail; the sliding base 122 has one side connected to the grid plate 111 and the other side slidably connected to the sliding rail 121 through a pulley, so that the grid plate 111 slides along the sliding rail 121 through the pulley. When the sliding base 122 slides on the sliding rail 121 through the pulley, the grating plate 111 and the louver 112 are driven to move synchronously. Here, the slide rail 121 may be erected in the cabinet 100 by a plurality of support rods.

Further, optionally, the air outlet 101 is configured as a rectangular opening with a vertical length direction, and the grating plate 111 is configured as a rectangular plate adapted to the air outlet 101. The sliding rail assembly 120 includes a sliding rail 121 disposed above the grid plate 111. One slider 122 is attached to the middle of the upper edge of the grid plate 111, or a plurality of sliders 122 are uniformly arranged along the upper edge of the grid plate 111.

Further, optionally, the sliding rail assembly 120 includes two sliding rails 121, and the two sliding rails 121 are respectively disposed on the upper and lower sides of the grid plate 111. The upper part of the grid plate 111 is connected to the upper side slide rail 121 by one or more slides 122, and the lower part of the grid plate 111 is connected to the lower side slide rail 121 by one or more slides 122. This makes the sliding of the grating plate 111 more stable.

Optionally, the indoor unit further includes a driving assembly, and the driving assembly is configured to drive the pulley to slide along the sliding rail 121. When the pulley slides along the sliding rail 121, the sliding base 122 is driven to move synchronously, and the sliding base 122 drives the grating plate 111 to move synchronously, so as to shield or avoid the air outlet 101.

Further, optionally, the drive assembly comprises a motor. The motor is disposed on the sliding base 122 and the driving shaft thereof is connected to the pulley, and the driving shaft of the motor drives the pulley to slide along the sliding rail 121 when rotating. The driving shaft of the motor directly penetrates through the center of the pulley, and the driving shaft drives the pulley to rotate when the motor is started.

Illustratively, a first end of the slide rail 121 corresponds to the air outlet 101, and a second end of the slide rail 121 is located away from the air outlet 101. When the motor rotates forward, the driving shaft drives the pulley to rotate and drives the sliding base 122 to move toward the first end of the sliding rail 121, so that the grille plate 111 gradually covers the air outlet 101. When the motor rotates reversely, the driving shaft drives the pulley to rotate and drives the sliding seat 122 to move towards the second end of the sliding rail 121, so that the grating plate 111 gradually gets out of the air outlet 101. Or, when the motor rotates reversely, the driving shaft drives the pulley to rotate and drives the sliding base 122 to move towards the first end of the sliding rail 121, so that the grille plate 111 gradually covers the air outlet 101. When the motor rotates forward, the driving shaft drives the pulley to rotate and drives the sliding base 122 to move towards the second end of the sliding rail 121, so that the grating plate 111 gradually gets out of the air outlet 101.

Optionally, the drive assembly further comprises a temperature sensor and a motor controller. The temperature sensor is used for detecting the indoor environment temperature; the motor controller is electrically connected to the motor and the temperature sensor, and the motor controller is configured to control the rotation of the motor according to the ambient temperature detected by the temperature sensor, so as to adjust the position of the grille relative to the air outlet 101.

Illustratively, when the indoor ambient temperature detected by the temperature sensor is greatly different from the target temperature set by the user, the indoor unit needs to perform cooling/heating quickly to meet the user's demand for temperature adjustment. In this case, the motor controller controls the motor driving pulley to slide along the slide rail 121 in a direction to avoid the air outlet 101, so that the slide seat 122 drives the grille plate 111 and the louver 112 to avoid the air outlet 101, and the air outlet of the air outlet 101 is not blocked by the louver 112. Because the louver 112 does not block the air outlet, the air outlet quantity of the air outlet 101 is maximum, and the speed of the indoor unit for changing the indoor environment temperature is increased.

As another example, when the indoor ambient temperature detected by the temperature sensor is smaller than the target temperature set by the user, the indoor unit does not need to perform rapid cooling/heating, but needs the grille plate 111 to completely shield the air outlet 101, so as to adjust the wind direction through the louver 112. In this case, the motor controller controls the motor driving pulley to slide along the sliding rail 121 to the direction of shielding the air outlet 101, so that the sliding base 122 drives the grating plate 111 and the louver 112 to shield the air outlet 101, and at this time, the air outlet direction of the air outlet 101 is guided by the louver 112, and the air blowing direction can be adjusted according to the requirement of the user.

Optionally, the indoor unit further includes a positioning assembly. The positioning component is used to determine the position of the grating plate 111 relative to the air outlet 101.

Further, optionally, the grid plate 111 has at least a shielding position and a storage position; the air outlet 101 is completely shielded when the grid plate 111 slides to the shielding position, and the air outlet 101 is completely avoided when the grid plate 111 slides to the accommodating position; the positioning assembly comprises two contact sensors, which are disposed on the slide rail 121 and respectively correspond to the shielding position and the storage position, and are triggered when the pulley slides to the corresponding position along the slide rail 121, so as to determine that the grid plate 111 slides in place. Both contact sensors are electrically connected to an indicator, which includes an indicator light disposed on an outer wall of the housing 100. When the contact sensor corresponding to the shielding position is triggered, the indicator controls the red light of the indicator light to light; when the contact sensor corresponding to the storage position is triggered, the green light of the indicator lamp is controlled by the indicator to light up, thus playing a role in prompting a user that the grid plate 111 has slid to the corresponding position.

In some embodiments, as shown in fig. 7, the housing 100 is provided with a receiving cavity 200 inside, the receiving cavity 200 is located at one side of the outlet 101, and the louver assembly 110 moves between the outlet 101 and the receiving cavity 200. The containing cavity 200 is provided with a rebounding door body 210, the shutter assembly 110 can be pushed open the door body 210 to enter or move out of the containing cavity 200 when moving, and the door body 210 rebounds to a closing position automatically after the shutter assembly 110 enters or moves out of the containing cavity 200.

By adopting the indoor unit provided by the embodiment of the disclosure, the accommodating position of the louver assembly 110 is located in the accommodating cavity 200, when the louver assembly 110 moves from the air outlet 101 to the accommodating cavity 200, namely the louver assembly 110 moves from the shielding position to the accommodating position, the louver assembly 110 pushes the door body 210 open to enter the accommodating cavity 200, and after the louver assembly completely enters the accommodating cavity 200, the door body 210 automatically rebounds to the closing position; when the louver assembly 110 moves from the accommodating cavity 200 to the air outlet 101, that is, the louver assembly 110 moves from the accommodating position to the shielding position, the louver assembly 110 pushes the door 210 open and moves out of the accommodating cavity 200, and after the louver assembly is completely moved out of the accommodating cavity 200, the door 210 automatically rebounds to the closing position. In this way, the shutter assembly 110 removed from the outlet 101 is conveniently received by the receiving cavity 200; and the accommodating cavity 200 is provided with the door body 210 which can rebound, so that the door body 210 does not need to be opened and closed manually, and the polluted air which enters the accommodating cavity 200 from the air outlet 101 outside the machine shell 100 can be reduced.

Optionally, as shown in fig. 5 and 6, an air duct volute 220 is provided in the casing 100, and the air duct volute 220 is used for installing a cross-flow fan. The airflow outlet of the duct volute 220 faces the air outlet 101 of the casing 100, and a side wall of a part of the duct volute 220 is located at one side of the air outlet 101 of the casing 100. Moreover, the side wall of the duct volute 220 on the side of the air outlet 101 and the inner wall of the casing 100 opposite to the side wall enclose a receiving chamber 200. After the louver assembly 110 slides into the accommodating cavity 200, the air outlet 101 is avoided. When the air outlet 101 is not shielded by any air, the air outlet quantity is maximum, and the indoor unit can rapidly refrigerate or rapidly heat.

Optionally, the door body 210 includes a door panel 211, and one side of the door panel 211 is connected to a side wall of the air duct volute 220 enclosing the receiving chamber 200 through a resilient hinge 212; alternatively, one side of the door panel 211 is connected to an inner wall of the cabinet 100 defining the receiving chamber 200 by a resilient hinge 212. The resilient hinge 212 has a two-way resilient function, and can cause the door panel 211 to be resilient from the outside of the storage cavity 200 to the outside of the storage cavity, and can also cause the door panel 211 to be resilient from the inside of the storage cavity 200 to the closed position. Under the action of the resilient hinge 212, the door panel 211 is pushed open to the inside or outside of the receiving cavity 200 by the louver assembly 110 and then can automatically return to the closed position.

Optionally, as shown in fig. 7, the door body 210 includes two door panels 211, where the two door panels 211 are disposed opposite to each other, and opposite sides of the two door panels 211 are connected to a side wall of the duct volute 220 and an inner wall of the casing 100, which enclose and define the receiving chamber 200, through the resilient hinges 212, respectively. The split door design of the door body 210 facilitates the louver assembly 110 to push the door panel 211 open, so as to facilitate the entering or moving out of the receiving cavity 200.

Further, optionally, a resilient hinge 212 is provided at each of upper and lower portions of each door panel 211, which makes the resilience of the door panel 211 more stable.

Further, optionally, when the door 210 is in the closed position, the opposite sides of the two door panels 211 abut against each other, so that contaminated air outside the casing 100 entering the receiving cavity 200 from the air outlet 101 can be greatly reduced. Alternatively, a gap is formed between the opposite sides of the two door panels 211, so that the louver assembly 110 can open the door body 210 from the gap between the two door panels 211.

Further, optionally, the edges of the opposite sides of the two door panels 211 are provided with anti-collision rubber strips. Because tripe subassembly 110 gets into or shifts out storage chamber 200 through the mode of pushing up open door body 210, can reduce the collision damage between tripe subassembly 110 and door plant 211 through crashproof adhesive tape.

Optionally, the first end of the slide rail 121 corresponds to the air outlet 101, and the second end of the slide rail 121 is located in the receiving cavity 200.

When the louver assembly 110 slides from the second end to the first end of the slide rail 121, the louver assembly 110 moves towards the air outlet 101, and when the louver assembly 110 contacts the door body 210 of the receiving cavity 200, the door body 210 is pushed open and continues to move towards the first end of the slide rail 121, and after the louver assembly 110 completely moves out of the receiving cavity 200, the door body 210 automatically rebounds to the closed position.

Optionally, in the case that the sliding rail assembly 120 includes one sliding rail 121, the sliding rail 121 extends into the receiving cavity 200 from above or below the door body 210. When the slide rail assembly 120 includes two slide rails 121, the two slide rails 121 respectively extend into the receiving cavity 200 from above and below the door body 210.

Further, optionally, in the case that the door body 210 includes two door panels 211, and the slide rail assembly 120 includes one slide rail 121, the slide rail 121 is located above or below the door seam of the two door panels 211. The door body 210 includes two door panels 211, and under the condition that the slide rail assembly 120 includes two slide rails 121, the slide rails 121 are located above and below the door gaps of the two door panels 211. The sliding rails 121 are arranged in such a way that the shutter assemblies 110 can push the door panel 211 open from the door slots, so as to enter or move out of the receiving cavity 200.
