The air conditioner comprises an indoor unit 1 and an outdoor unit, wherein the indoor unit 1 is arranged indoors, the outdoor unit is arranged outdoors, and the indoor unit 1 and the outdoor unit are connected through a pipeline and an electric wire.

Air conditioners include wall-mounted, cabinet-mounted, ceiling-mounted, embedded and floor-mounted.

As shown in fig. 1, an embodiment of the present disclosure provides an indoor unit 1, where the indoor unit 1 includes an indoor unit body 2, and the indoor unit body 2 defines an air duct 3. The indoor unit 1 further comprises an adjusting plate 4, the adjusting plate 4 is arranged in the air duct 3, the adjusting plate 4 is movably connected with the indoor unit main body 2 so as to move relative to the indoor unit main body 2, and the adjusting plate 4 is used for changing the flow area of the air duct 3.

By adopting the indoor unit 1 provided by the embodiment of the disclosure, the adjusting plate 4 is arranged in the air duct 3, the flow area of the air duct 3 is changed when the adjusting plate 4 moves relative to the indoor unit main body 2, the width of the air duct 3 is correspondingly changed, the air duct 3 is adjustable, the air duct 3 which is matched with air with different temperatures is found, the energy loss in the air supply process of the air conditioner is reduced, and therefore the refrigerating or heating effect of the air conditioner is improved. Compared with the related art, the flow area of the air outlet 32 of the air duct 3 is controlled by the adjusting plate 4 instead of being fixed, so that the flow area of the air outlet 32 can be flexibly adjusted by the adjusting plate 4 according to the air outlet mode or the selection of a user, and the satisfaction degree of the user is enhanced.

Alternatively, as shown in fig. 1 to 6, the regulating plate 4 moves between the fitting position 5 and the projecting position 6 with respect to the indoor unit main body 2. Wherein, at the attaching position 5, the adjusting plate 4 is attached to the inner wall surface 31 of the air duct 3; in the extended position 6, the downstream end 42 of the adjustment plate is less distant from the tunnel axis 33 than the upstream end 41 of the adjustment plate is distant from the tunnel axis 33. The upstream and downstream are defined by the flow direction of air in the duct 3 (the direction indicated by the arrow in fig. 6), and the air in the duct 3 flows from the upstream to the downstream.

Like this, when the regulating plate 4 is in laminating position 5, as shown in combining fig. 2 and 3, regulating plate 4 is laminated with the internal face 31 of wind channel 3, and wind channel 3 widens, and wind channel 3 obtains the biggest flow area this moment, is convenient for fully release the heat or the cold volume of heat exchanger gathering, enlarges the heat transfer area with indoor normal atmospheric temperature air to promote heating or refrigeration effect. Referring to fig. 4 to 6, when the adjusting plate 4 is located at the extending position 6, compared with the upstream end 41 of the adjusting plate, the downstream end 42 of the adjusting plate is closer to the air duct axis 33, which means that the adjusting plate 4 is disposed in the air duct 3 obliquely to the air duct axis 33, the air duct 3 is narrowed, the flow area of the air duct 3 is reduced, the heat or cold accumulated by the heat exchanger can be conveniently and rapidly released in a concentrated manner, and the heat exchange speed with indoor room temperature air is accelerated, so as to improve the heating or cooling effect. In the process of moving between the attaching position 5 and the extending position 6 relative to the indoor unit main body 2, the width of the air duct 3 is changed, the flow area of the air outlet 32 is flexibly adjusted, and the refrigerating or heating effect is improved.

Alternatively, as shown in fig. 1, the number of the regulating plates 4 is one or plural, and when plural, the plurality of regulating plates 4 are disposed in order along the width direction of the inner wall surface 31 of the air duct 3.

Like this, through setting up the flow area of a plurality of regulating plates 4 common regulation wind channel 3, the flexibility is bigger, can obtain more flow area, satisfies user's demand better.

Alternatively, the upstream end 41 of the adjusting plate is rotatably connected to the indoor unit main body 2, and the downstream end 42 of the adjusting plate is rotated around the upstream end 41 of the adjusting plate.

In this way, the upstream end 41 of the adjusting plate is fixed, the downstream end 42 of the adjusting plate rotates around the upstream end 41 of the adjusting plate, and during rotation, the adjusting plate 4 and the joint form an included angle 8 (as shown in fig. 5), and the included angle 8 is opened towards the downstream direction of the air duct 3. The upstream end 41 of the adjusting plate is connected with the indoor unit main body 2, and the air can be blocked from flowing through a space formed by the included angle 8 without installing a sealing element at the included angle 8, so that the structure is simpler.

Optionally, the downstream end 42 of the regulator plate is located at the air outlet 32 of the air duct 3.

At present, most of household air conditioners in the market are fixed air channels 3, and an air deflector structure and a swing blade structure are arranged at an air outlet 32 to realize wind direction change. Specifically, cold air or hot air is sent into a designated refrigerating or heating space through the up-and-down movement of the transverse air guide plate structure and the left-and-right movement of the longitudinal swing blade structure. However, since the air-out resistance is large and the air-out quantity is small, the refrigerating or heating effect on the designated space is not obvious. In the related art, the positions of the air outlet of the refrigerating air duct and the air outlet of the refrigerating air duct are fixed, and cold air or hot air cannot be sent into a designated refrigerating or heating space.

By adopting the indoor unit 1 provided by the embodiment of the disclosure, the downstream end 42 of the adjusting plate is positioned at the air outlet 32 of the air duct 3, and different air outlet orientations are obtained by controlling the downstream end 42 of the adjusting plate at different positions of the air outlet 32, so that the refrigeration or heating of a specified space is realized.

Optionally, in the engaged position 5, the downstream end 42 of the adjustment plate is lower than the upstream end 41 of the adjustment plate.

In the bonding position 5, the downstream end 42 of the conditioning plate is lower than the upstream end 41 of the conditioning plate, enabling air to flow from the upstream end 41 of the conditioning plate to the downstream end 42 of the conditioning plate.

Alternatively, as shown in conjunction with fig. 2 and 6, in the fitting position 5, the regulating plate 4 is fitted with the inner wall surface 312 of the top wall of the air duct 3.

When the adjusting plate 4 is at the attaching position 5, the adjusting plate 4 is attached to the inner wall surface 312 of the top wall of the air duct 3, the air duct 3 is widened, the air duct 3 obtains the maximum flow area at the moment, heat or cold accumulated by the heat exchanger is conveniently and fully released, and the heat exchange area with indoor normal-temperature air is enlarged, so that the heating or refrigerating effect is improved. When the adjusting plate 4 is positioned at the stretching-in position 6, the air duct 3 is narrowed, the flow area of the air duct 3 is reduced, the heat or cold accumulated by the heat exchanger is conveniently and intensively and rapidly released, and the heat exchange speed with indoor normal-temperature air is accelerated, so that the heating or refrigerating effect is improved.

For example, in the heating mode, when the adjusting plate 4 is at the extending position 6, the downstream end 42 of the adjusting plate is lower than the upstream end 41 of the adjusting plate, so that the air can be promoted to flow downwards, the space below the air outlet 32 can be heated, and the effect of warming feet can be achieved. In the cooling mode, when the adjusting plate 4 is located at the extending position 6, the downstream end 42 of the adjusting plate is lower than the upstream end 41 of the adjusting plate, so that air can be promoted to flow downwards, and the cooling air can quickly descend to the bottom end of the cooling space due to high density of the cooling air, so that the cooling speed is improved.

The difference from the fact that the adjusting plate 4 is mounted on the inner wall surface 312 of the top wall of the air duct 3 is that the air outlet 32 is oriented differently when the adjusting plate 4 is extended into the position 6. Specifically, when the regulating plate 4 is mounted on the inner wall surface 312 of the top wall, in the extended position 6, the downstream end 42 of the regulating plate is lower than the upstream end 41 of the regulating plate, and the air outlet 32 is downward; when the regulating plate 4 is mounted on the inner wall surface 311 of the bottom wall, the downstream end 42 of the regulating plate is higher than the upstream end 41 of the regulating plate at the projecting position 6, and the air outlet 32 is directed upward.

For example, the adjusting plate 4 is mounted on the inner wall surface 311 of the bottom wall of the air duct 3, and in the cooling mode, when the adjusting plate 4 is at the extending position 6, the downstream end 42 of the adjusting plate is higher than the upstream end 41 of the adjusting plate, so that air can be promoted to flow upwards, cooling of the space above the air outlet 32 is realized, and the effect of preventing direct blowing during cooling is achieved.

In the cooling mode, when the adjusting plate 4 is located at the extending position 6, the downstream end 42 of the adjusting plate is higher than the upstream end 41 of the adjusting plate, so that air can be promoted to flow upwards, cooling of the space above the air outlet 32 is achieved, and the effect of direct blowing prevention during cooling is achieved.

When the regulating plate 4 is mounted on the inner wall surface 312 of the top wall of the air duct 3, the regulating plate 4 moves between the inner wall surface 312 of the top wall of the air duct 3 and the projecting position 6 with respect to the indoor unit main body 2. In the cooling mode, when the adjusting plate 4 is located at the extending position 6, the downstream end 42 of the adjusting plate is lower than the upstream end 41 of the adjusting plate, so that air can be promoted to flow downwards, and the cooling air can quickly descend to the bottom end of the cooling space due to high density of the cooling air and high descending speed, so that the cooling speed is improved.
