Hereinafter, embodiments according to the present utility model will be described in detail with reference to the accompanying drawings.

The air conditioner of the present utility model performs a refrigerating cycle of the air conditioner by using a compressor, a condenser, an expansion valve, and an evaporator. The refrigeration cycle includes a series of processes involving compression, condensation, expansion, and evaporation, and supplies a refrigerant to the air that has been conditioned and heat exchanged.

The compressor compresses refrigerant gas in a low-temperature and low-pressure state and discharges the compressed refrigerant gas. The discharged refrigerant gas flows into the condenser. The condenser condenses the compressed refrigerant into a liquid phase, and heat is released to the surrounding environment through the condensation process.

The expansion valve expands the liquid-phase refrigerant in a high-temperature and high-pressure state condensed in the condenser into a low-pressure liquid-phase refrigerant. The evaporator evaporates the refrigerant expanded in the expansion valve and returns the refrigerant gas in a low-temperature and low-pressure state to the compressor. The evaporator may achieve a cooling effect by exchanging heat with a material to be cooled using latent heat of evaporation of a refrigerant. The air conditioner may adjust the temperature of the indoor space throughout the cycle.

An outdoor unit of an air conditioner refers to a portion of a refrigeration cycle including a compressor and an outdoor heat exchanger, an indoor unit of the air conditioner includes an indoor heat exchanger, and an expansion valve may be provided in the indoor unit or the outdoor unit.

The indoor heat exchanger and the outdoor heat exchanger function as a condenser or an evaporator. When the indoor heat exchanger is used as a condenser, the air conditioner is used as a heater of a heating mode, and when the indoor heat exchanger is used as an evaporator, the air conditioner is used as a cooler of a cooling mode.

The indoor unit of the present utility model may be a wall-mounted indoor unit installed on a wall of an indoor space. However, in other embodiments, the present utility model is also applicable to other forms of indoor units.

Hereinafter, for convenience of description, the indoor unit is referred to as an air conditioner, the indoor heat exchanger is referred to as a heat exchanger, and the indoor fan is referred to as a fan.

Referring to fig. 1 and 2, the air conditioner includes a housing 1, and a plurality of components constituting a refrigeration cycle are installed in the housing 1. The housing 1 includes a cover 11 and a base 12. The rear side of the housing 11 is opened, and the base 12 is attached to the opened portion of the housing 11 to constitute the rear surface of the casing 1.

The housing 11 includes a front panel 111, upper and lower panels 112 and 113 connected to upper and lower ends of the front panel 111, and two side panels 114 connected to left and right sides of the front panel 111.

The upper panel 112 is formed with an air inlet 115. An air inlet grill that guides air to the air inlet 115 may be provided on the upper panel 112.

The lower end of the front panel 111 forms an opening-shaped air outlet 116. The air conditioner may include an air deflector 2 that opens/closes the air outlet 116. The air deflector 2 is rotatably provided in the housing 1. Specifically, the air deflector 2 is rotatable about an axis relative to the air outlet 116.

In the present example, the front panel 111 is a curved plate that protrudes forward. In other examples, the front panel 111 may also be a flat plate or other shape.

The heat exchanger may be disposed inside the case 1, and may be disposed on an air moving path from the air inlet 115 to the air outlet 116. The heat exchanger is used to absorb heat from or transfer heat to the air introduced into the air intake 115.

The fan is disposed inside the housing 1. The fan is used to blow air so that air may flow from the air inlet 115 to the air outlet 116. The fan may be a cross flow fan having the same longitudinal direction as the housing 1.

According to an embodiment of the present utility model, referring to fig. 3 to 5, an air duct from an air inlet 115 to an air outlet 116 is formed on the base 12, wherein a tail section of the air duct is called an air outlet cavity 120, and the air outlet cavity 120 is disposed corresponding to the air outlet 116; it can also be said that the air outlet 116 is located on the extension of the air outlet chamber 120.

One end of the air deflector 2 is connected with a motor 3, and the motor 3 provides rotary driving force for the air deflector 2. The other end of the air deflector 2 is provided with a first rotating shaft 21, and the first rotating shaft 21 is inserted into the side wall of the air outlet cavity 120. The air deflector 2 rotates at the air outlet cavity 120 under the drive of the motor 2, and when the air deflector 2 is correspondingly positioned at the air outlet 116, the air outlet 116 is closed; when the air deflection 2 rotates outwards, the air outlet 116 is opened.

Referring to fig. 5, 6, 7 and 9, the air conditioner further includes a first shaft housing 4, and the first shaft housing 4 is mounted on a sidewall of the air outlet chamber 120. Specifically, a first accommodating portion 121 is provided on a side wall of the air outlet cavity 120, and the first shaft sleeve 4 is connected in the first accommodating portion 121. The first shaft 21 is then inserted into the first sleeve 4, i.e. the first sleeve 4 is located between the first shaft 21 and the first receptacle 121.

According to an embodiment of the present utility model, referring specifically to fig. 9, a plurality of outwardly protruding bosses 22 are provided at intervals on the peripheral portion of the first shaft 21, and the outer peripheral surface of the boss 22 is circular and concentric with the first shaft 21, so that when the wind deflector 2 rotates, the first shaft 21 rotates in the first shaft sleeve 4, and the boss 22 contacts with the inner wall of the first shaft sleeve 4.

Since the area of the boss 22 is relatively small with respect to the entire circumferential surface of the first rotary shaft 21, the boss 22 is in contact with the first shaft sleeve 4, so that the operation process is smooth due to the contact of the small area on the one hand, and noise and vibration generated during the contact of the large area are reduced on the other hand.

The bosses 22 are uniformly distributed on the first rotating shaft 21, so that circumferential stress balance between the first rotating shaft 21 and the first shaft sleeve 4 can be ensured, and the running stability of the air deflector 2 can be ensured.

According to an embodiment of the present utility model, in a radial cross section, the sum L of the outer circumferential lengths of the bosses 22 ₁ With the circumference L of the first rotation shaft 21 ₂ The relation of (2) is as follows: l (L) ₁ ≤1/2L ₂ The number of the bosses 22 is not less than 3, so that the bosses 22 can be ensured to have smaller area and smooth matching with the first shaft sleeve 4.

L is the same as ₂ The boss 22 is removed, and the circumference of the first rotation shaft 21 is removed.

In the present example, the number of bosses 22 is 4,L ₁ ＝1/2L ₂ 。

according to an embodiment of the present utility model, the first sleeve 4 is clamped in the first accommodating part 121.

Specifically, the first sleeve 4 includes a penetrating portion 44 and a stopping portion 45, wherein the stopping portion 45 is located at one end of the penetrating portion 44, and an outer diameter of the stopping portion 45 is larger than that of the penetrating portion 44.

The end of the penetrating part 44 far away from the stopping part 45 is provided with a convex clamping block 41, the first shaft sleeve 4 is penetrated in the first accommodating part 121, and the first accommodating part 121 is clamped between the clamping block 41 and the stopping part 45, so that the first shaft sleeve 4 is connected at the first accommodating part 121.

The clamping blocks 41 are small bulges arranged on the periphery of the first shaft sleeve 4, and a plurality of clamping blocks 41 are arranged at intervals along the circumferential direction so as to ensure the blocking effect.

The first sleeve 4 is provided with a notch 43 at one end (free end) remote from the air deflector 2, the notch 43 penetrating the side wall of the first sleeve 4 in the radial direction, so that the first sleeve 4 can deform when being stressed.

Specifically, the notch 43 extends from the free end of the penetrating portion 44 toward the stopper portion 45 in the axial direction, extends to the stopper portion 45 or is adjacent to the stopper portion 45, and in the radial direction, the notch 43 penetrates the side wall of the penetrating portion 44 to divide the penetrating portion 44 into a plurality of segments.

In the process of penetrating the first accommodating portion 121, when the fixture block 41 of the first shaft sleeve 4 penetrates the first accommodating portion 121, the penetrating portion 44 is subjected to inward pressing force to be folded and deformed, and after the fixture block 41 penetrates the first accommodating portion 121, the shape of the penetrating portion 44 is restored. When the end surface of the first accommodating portion 121 abuts against the latch 41, the continued movement of the first sleeve 4 is restricted.

The latch 41 is provided with a chamfer so that the latch 41 can serve as a guide when penetrating the first receiving portion 121.

The two notches 43 allow the first sleeve 41 to be easily deformed when being stressed, and ensure the structural strength of the first sleeve 41.

The width of the boss 22 is not smaller than the width of the notch 43, so that the boss 22 can be prevented from entering the notch 43, and the effective rotation of the first rotating shaft 21 in the first shaft sleeve 4 is ensured.

According to an embodiment of the present utility model, referring to fig. 3 and 5, a through hole 122 is further provided on a sidewall of the air outlet cavity 120, and the through hole 122 and the first accommodating portion 121 are located at opposite ends of the air outlet cavity 120.

In the current example, the first receiving part 121 is located at the left end and the through-hole 122 is located at the right end.

The motor 3 is arranged on the outer right side wall of the air outlet cavity 120, and a motor shaft of the motor 3 penetrates through the through hole 122 to be connected with the right end of the air deflector 2.

In some embodiments, referring to fig. 5, 6, 8 and 10, a support portion 123 is provided at a middle portion of the air outlet chamber 120, and a second receiving portion 124 is provided on the support portion 123.

The middle part of the air deflector 2 is provided with a second rotating shaft 24, the second rotating shaft 24 is coaxial with the first rotating shaft 21, and the second rotating shaft 24 is inserted into the second accommodating part 124. The supporting part 124 can support the middle part of the air deflector 2, so that the problem that the middle part of the air deflector 2 is easy to deform under the action of gravity when being used as an elongated member is avoided.

Likewise, a second bushing 5 is provided between the second rotating shaft 24 and the second receiving portion 124. The second sleeve 5 has the same structure as the first sleeve 4, and will not be described herein.

According to the embodiment of the utility model, the air deflector 2 is provided with an extension part 23, and the second rotating shaft 24 is formed by extending transversely from the extension part 23. The end of the second rotating shaft 24 connected with the extension portion 23 is a connecting end, the other end opposite to the connecting end is a free end, and the free end of the second rotating shaft 24 is provided with a blocking portion 25 protruding outwards.

The blocking part 25 penetrates through the second shaft sleeve 5, and when the blocking part 25 abuts against the end face of the second shaft sleeve 5, the second rotating shaft 24 can be limited to move relative to the second shaft sleeve 5. Therefore, due to the position limiting effect of the baffle part 25, the left and right movement of the air deflector 2 in the running process can be avoided, the left and right clearance between the air deflector 2 and the outer cover 11 is ensured to be consistent, and the attractiveness of the air conditioner is improved.

The blocking parts 25 are arranged at intervals on the circumference of the second rotating shaft 24, so that the balance and reliability of the blocking effect can be ensured.

In some embodiments, the second shaft 24 also has a boss 22 thereon, and the structure and function of the boss 22 are the same as those of the first shaft 21, which will not be described herein.

The stop 25 is provided on the boss 22, i.e. the boss 22 has an outwardly protruding portion which forms the stop 25.

The blocking parts 25 are in one-to-one correspondence with the bosses 22, and each boss 22 corresponds to one blocking part 25.

In the present example, the second rotating shaft 24 is formed by extending the extending portion 23 to the left, the left end of the second rotating shaft 24 is a free end thereof, the right end is a connecting end thereof, and the blocking portion 25 is disposed at the free end of the second rotating shaft 24.

In the assembled state, when the left end face of the second sleeve 5 abuts against the blocking part 25, the second rotating shaft 25 can be prevented from continuously moving rightwards; meanwhile, the right end of the second shaft sleeve 5 limits the left movement of the second rotating shaft 25, so that the left and right movement of the second rotating shaft 5 is limited, and the second rotating shaft 5 is connected to the air deflector 2, namely, the left and right movement of the air deflector 2 is limited, and the left and right movement of the air deflector 2 in the running process of the air conditioner is avoided.

In some embodiments, the connecting end of the second shaft 24 has an outer protruding portion 26, and the outer diameter of the outer protruding portion 26 is larger than the inner diameter of the second sleeve 5, so that the outer protruding portion 26 may form a limit for the second sleeve 5.

That is, the second sleeve 5 is caught between the stopper 25 and the outer flange 26.

In some embodiments, the width of the stop 25 is greater than the width of the notch 43 on the second hub 5, such that entry of the stop 25 into the notch 43 is avoided.

According to the first conception of the utility model, the boss 22 is arranged on the rotating shaft of the air deflector 2, and the boss 22 is contacted with the shaft sleeve because the area of the boss 22 is relatively smaller than the whole circumferential surface of the rotating shaft, so that the operation process is stable due to the contact of the boss 22 with the shaft sleeve in a small area, and noise and vibration generated during the contact in a large area are reduced.

In the second concept of the present utility model, the protruding blocking portion 25 is disposed at the free end of the second rotating shaft 24, so that the blocking portion 25 can limit the movement of the second rotating shaft 24 relative to the second sleeve 5. Therefore, due to the position limiting effect of the baffle part 25, the left and right movement of the air deflector 2 in the running process can be avoided, the left and right clearance between the air deflector 2 and the outer cover 11 is ensured to be consistent, and the attractiveness of the air conditioner is improved.
