It should be noted that the air deflector 20 is rotatably installed at the air outlet 11, and the air deflector 20 can be rotatably installed to guide air left and right or up and down.
It should be noted that the bimetal 33 may include not only 2 layers of metals with different thermal expansion coefficients, but also multiple layers of metals with different thermal expansion coefficients, and the number of layers of the metals with different thermal expansion coefficients is not particularly limited.
In an embodiment, the bimetal 33 is in a strip shape, the bimetal 33 is located at an outer side of the maximum opening angle of the air deflector 20 in a normal temperature or refrigeration state and does not contact with the air deflector 20, when the bimetal 33 is deformed by heating, the free end 31 presses the air deflector 20 to rotate the air deflector 20 in a closing direction, and finally the air deflector 20 rotates in an angle favorable for blowing hot air downwards.
According to the air conditioner indoor unit provided by the utility model, the bimetallic strip 33 is deformed by heating to push the air deflector 20 to rotate towards the direction for closing the air outlet 11, an electric appliance is not required to drive and control the air deflector 20 to rotate, the bimetallic strip 33 drives the air deflector 20 to rotate at different angles to meet different air guiding direction requirements during refrigeration or heating, the reliability is improved, the service life is prolonged, and the structure is simpler.
Referring to fig. 4 to 6, because the precision of the elongated or straight bimetal 33 is not sufficient, in an embodiment, the bimetal 33 is disposed in a coil spring structure, the driving member 30 further includes a push rod 34, the bimetal 33 has a first inner end 33a and a first outer end 33b, the first inner end 33a is a free end 31, the first outer end 33b is a fixed end 32, one end of the push rod 34 abuts against the air guiding plate 20, and the other end is connected to the free end 31. The coil spring structure is a spiral bimetallic strip 33, the bimetallic strip 33 arranged in the coil spring structure deforms and rotates when heated, the first inner end 33a pushes the push rod 34 to rotate the push rod 34, the push rod 34 turns to the air deflector 20, and the push rod 34 pushes the air deflector 20 to rotate in a direction of closing the air outlet 11.
The bimetal 33 is curved with a certain radius when heated, so that the change in the transverse direction is not large, and in an embodiment, the length of the bimetal 33 is more than 3 times of the width thereof, or the width of the bimetal 33 is not more than 20 times of the thickness thereof.
In order to ensure that the bimetal 33 can be bent toward the air deflector 20 instead of being bent back to the air deflector 20 when being heated, in an embodiment, the metal sheet with a high thermal expansion coefficient in the bimetal 33 is located at an opposite position of the deformation direction of the bimetal 33, that is, the alloy with a large expansion coefficient is located at a side far away from the air deflector 20, and the alloy with a small expansion coefficient is located at a side close to the air deflector 20, so that the bimetal 33 can be pushed against the air deflector 20 when being heated, and the air deflector 20 is pushed to rotate in a direction of closing the air outlet 11.
Referring to fig. 7 and 8, the bimetal is divided into a temperature bimetal and a humidity bimetal, and is an element that deforms when the temperature or humidity changes and is generally formed by overlapping two layers of alloys with different expansion coefficients. The active layer 35 with a large expansion coefficient is called an active layer 35, the passive layer 36 with a small expansion coefficient is called a passive layer 36, the active layer 35 is mainly made of manganese-nickel-copper alloy, nickel-chromium-iron alloy, nickel-manganese-iron alloy or nickel, and the like, the passive layer 36 is mainly made of nickel-iron alloy, and the content of nickel is 34-50%. The working principle is that due to the difference of the expansion coefficients of the metals, when the temperature or the humidity changes, the deformation of the active layer 35 is larger than that of the passive layer 36, so that the whole bimetallic strip 33 bends towards one side of the passive layer 36 to generate deformation. Generally, the bimetal 33 is made of nickel-iron alloy and brass, and is required to have good elasticity to ensure the accuracy of temperature control and the reusability.
Referring to fig. 9 and 10, the indoor unit of an air conditioner includes a plurality of air deflectors 20, the plurality of air deflectors 20 include second outer ends 21 located outside the air outlet 11 and second inner ends 22 located inside the air outlet 11, and the indoor unit of an air conditioner further includes a counterweight connecting rod 40, and the counterweight connecting rod 40 is connected to the second inner ends 22 of the plurality of air deflectors 20.

It should be noted that the wind may blow the air deflector 20 to rotate in a direction of opening the air outlet 11, and the bimetal 33 deforms when heated to push the air deflector 20 to rotate in a direction of closing the air outlet 11, so that the wind and the bimetal 33 are resistant to each other.
The counterweight connecting rod 40 and the air deflector 20 are similar to two ends of a balance, the counterweight connecting rod 40 can counteract most of the weight of the air deflector 20 so as to balance the gravity of the air deflector 20, when the weight of two sides is almost the same, the air deflector 20 can be easily blown away by wind, if no counterweight is provided, the air deflector 20 is difficult to blow away by wind, and the wind consumes great energy. The weight of the counterweight connecting rod is appropriate, the weight cannot be too large or too small, when the weight is too large, the air deflector 20 is always in a state of opening at the maximum angle, so that the bimetal 33 is difficult to push the air deflector 20 to rotate towards the direction of closing the air outlet 11, when the weight is too small, the air deflector 20 approaches to a closed state, and at the moment, wind is difficult to blow the air deflector 20 to rotate towards the direction of opening the air outlet 11.
The counterweight connecting rod 40 is preferably connected to the second inner ends 22 of the air deflectors 20, not between the second inner ends 22 and the second outer ends 21 of the air deflectors 20, but not connected to the second outer ends 21 of the air deflectors 20, and when the counterweight connecting rod 40 is connected to the second inner ends 22 of the air deflectors 20, the counterweight connecting rod 40 more easily offsets most of the weight of the air deflectors 20, and wind more easily blows the air deflectors 20 to rotate in a direction of opening the air outlet 11.
Referring to fig. 11 to 13, the counterweight connecting rod 40 has a counterweight function and a linkage function for the air deflectors 20, the second inner end 22 is convexly provided with a fixing column 23, the counterweight connecting rod 40 is provided with a through hole 41, and the counterweight connecting rod 40 is sleeved on the fixing column 23 through the through hole 41, so that the air deflectors are connected together to realize synchronous linkage.
The counterweight connecting rod 40 connects the air deflectors 20 together, so that the air deflectors 20 can rotate synchronously, that is, only one bimetallic strip 33 can be provided, when the bimetallic strip 33 pushes one air deflector 20 to rotate in the direction of closing the air outlet 11, the counterweight connecting rod 40 drives the air deflectors 20 to rotate synchronously, the number of the bimetallic strips 33 is not limited here, the number of the bimetallic strips 33 can be only 1 or 2, and the number of the bimetallic strips 33 can also be more than 2.
Because the space in the casing 10 is limited, the counterweight connecting rod 40 is installed outside the casing 10, the casing 10 is provided with the abdicating hole 12, the fixing column 23 passes through the abdicating hole 12 to be connected with the counterweight connecting rod, the abdicating hole 12 is arranged in an arc shape, when the air deflector 20 rotates, the fixing column 23 can move in the abdicating hole 12, the abdicating hole 12 can also be circular or square, the shape of the abdicating hole 12 is not particularly limited, as long as the abdicating hole 12 can satisfy the normal moving distance of the fixing column 23 in the abdicating hole 12, and the extending length of the abdicating hole 12 just satisfies the requirement of the rotation angle of the air deflector 20.
