Detailed Description
The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
The air conditioner performs a refrigeration 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 refrigerant to the air that has been conditioned and heat-exchanged.
The compressor compresses a refrigerant gas in a high-temperature and high-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 can achieve a cooling effect by heat-exchanging with a material to be cooled using latent heat of evaporation of a refrigerant. The air conditioner can adjust the temperature of the indoor space throughout the cycle.
The outdoor unit of the air conditioner refers to a portion of a refrigeration cycle including a compressor and an outdoor heat exchanger, the 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 serve as a condenser or an evaporator. When the indoor heat exchanger is used as a condenser, the air conditioner is used as a heater in a heating mode, and when the indoor heat exchanger is used as an evaporator, the air conditioner is used as a cooler in a cooling mode.
An air conditioner indoor unit 100 according to an embodiment of the present invention will be described with reference to fig. 1 to 9.
As shown in fig. 1, an air conditioner according to some embodiments of the present application includes an air conditioner indoor unit 100 installed in an indoor space. The indoor unit 100, i.e., the indoor unit, is connected to an outdoor unit, i.e., the outdoor unit (not shown), installed in an outdoor space, through a pipe. The outdoor unit of the air conditioner may be provided with a compressor, an outdoor heat exchanger, an outdoor fan, an expander, and the like of a refrigeration cycle, and the indoor unit 100 may be provided with an indoor heat exchanger and an indoor fan.
The air conditioner indoor unit 100 may include a wall-mounted air conditioner indoor unit installed on the floor of an indoor space, among others.
As shown in fig. 1, 6 and 8, an air conditioner 100, such as a wall-mounted air conditioner, according to an embodiment of the present invention includes a body 1, a wind guide plate 2, at least one first driving assembly 3 and at least one second driving assembly 4.
An air outlet 11 is formed on the machine body 1. The air deflector 2 is disposed at the air outlet 11 to open and close the air outlet 11, and the air deflector 2 has a first end and a second end, the first end is an upper end when the air deflector 2 closes the air outlet 11, and the second end is a lower end when the air deflector 2 closes the air outlet 11.
For example, in conjunction with fig. 1, 6 and 8, the air deflection plate 2 extends in the left-right direction, and the air deflection plate 2 may be an arc-shaped plate. When the air conditioner is in a shutdown state or a standby state, the air deflector 2 closes the air outlet 11 to prevent external impurities such as dust or insects from entering the interior of the machine body 1; when the air conditioner is started, the air deflector 2 rotates relative to the machine body 1 under the drive of the first drive assembly 3 and the second drive assembly 4 to open the air outlet 11, so that the air outlet 11 can be exposed, and cold air or warm air can be blown into a room from the air outlet 11 to adjust the indoor temperature.
As shown in fig. 2 to 4, the first driving assembly 3 is disposed between the machine body 1 and the first end of the air guiding plate 2, and the first driving assembly 3 is detachably engaged with the first end of the air guiding plate 2. The second driving assembly 4 is arranged between the machine body 1 and the second end of the air deflector 2, and the second driving assembly 4 is detachably matched with the second end of the air deflector 2. That is, the first driving assembly 3 and the first end of the air guiding plate 2 can be matched with each other or separated from each other; the second driving assembly 4 and the second end of the air deflector 2 can be mutually matched or separated.
Specifically, referring to fig. 8 and 9, the first driving assembly 3 is engaged with the first end of the air guiding plate 2, when the first driving assembly 3 works, the first driving assembly 3 drives the air guiding plate 2 to rotate around the first end of the air guiding plate 2, and the second end of the air guiding plate 2 is suitable for being separated from the second driving assembly 4.
For example, when the air conditioner is in a shutdown state or a standby state, referring to fig. 3, the first driving assembly 3 is engaged with the first end of the air guiding plate 2, and the second driving assembly 4 is engaged with the second end of the air guiding plate 2, so that the rotation of the air guiding plate 2 can be limited, and the air guiding plate 2 can close the air outlet 11.
When the air conditioner operates in the heating mode, with reference to fig. 8 and 9, the first driving assembly 3 can be kept in cooperation with the first end of the air deflector 2, the second end of the air deflector 2 rotates clockwise relative to the machine body 1 to open the air outlet 11, at this time, the lower portion of the air deflector 2 is opened, air flow can be blown out obliquely and downwards under the air guiding effect of the air deflector 2, and due to the fact that the air flow temperature is high, light air flow can float upwards indoors, and 'carpet heating' is achieved, so that the heating effect of the air conditioner indoor unit 100 can be improved, and the use comfort of a user is improved.
Referring to fig. 6 and 7, the second driving assembly 4 is engaged with the second end of the air guiding plate 2, when the second driving assembly 4 works, the second driving assembly 4 drives the air guiding plate 2 to rotate around the second end of the air guiding plate 2, and the first end of the air guiding plate 2 is suitable for being separated from the first driving assembly 3.
For example, in the example of fig. 6 and 7, when the air conditioner operates in the cooling mode, the second driving assembly 4 may be kept in cooperation with the second end, the first end of the air deflector 2 rotates counterclockwise relative to the first driving assembly 3 to open the air outlet 11, at this time, the upper side of the air deflector 2 is opened, the air flow may be blown out horizontally forward or obliquely upward under the action of the air deflector 2, and due to the low air flow temperature, the heavier air flow may sink indoors, so as to achieve "shower cooling", thereby improving the cooling effect of the air conditioner indoor unit 100, and improving the comfort of the user.
Therefore, through the arrangement, the air deflector 2 can flexibly change the position of the rotating shaft according to the refrigeration mode or the heating mode of the air conditioner, so that air flow can be blown out forwards or upwards in an inclined mode in the refrigeration mode, and can be blown out downwards in the heating mode, the air conditioner can be ensured to have better refrigeration effect and heating effect, and the use comfort of a user is improved.
According to the air conditioner indoor unit 100, such as a wall-mounted air conditioner indoor unit, in the embodiment of the invention, at least one first driving assembly 3 is arranged between the machine body 1 and the first end of the air deflector 2, and at least one second driving assembly 4 is arranged between the machine body 1 and the second end of the air deflector 2, so that when the first driving assembly 3 works, the first driving assembly 3 drives the air deflector 2 to rotate around the first end of the air deflector 2, the second end of the air deflector 2 is suitable for being separated from the second driving assembly 4, and when the second driving assembly 4 works, the second driving assembly 4 drives the air deflector 2 to rotate around the second end of the air deflector 2, the first end of the air deflector 2 is suitable for being separated from the first driving assembly 3, and the rotating shaft of the air deflector 2 can be flexibly changed, so that the refrigeration effect and the heating effect of the air conditioner can be improved, and a user is ensured to have higher use.
In some embodiments of the present invention, as shown in fig. 2-4, 7 and 9, the first drive assembly 3 and the second drive assembly 4 each include a drive motor 31. The driving motor 31 is disposed on the machine body 1, the driving motor 31 has an output shaft 311, and the output shaft 311 is detachably engaged with the first end or the second end of the air guiding plate 2.
For convenience of description, the driving motor 31 of the first driving assembly 3 is referred to as a "first driving motor", and the driving motor 31 of the second driving assembly 4 is referred to as a "second driving motor". For example, in the examples of fig. 6 to 9, when the air conditioner is in the cooling mode, the output shaft 311 of the second driving motor is engaged with the second end, and when the second driving motor is operated, the output shaft 311 of the second driving motor drives the air deflector 2 to rotate around the second end of the air deflector 2, and the first end of the air deflector 2 is separated from the first driving motor, so that the air flow can be blown out horizontally forward or obliquely upward, thereby improving the cooling effect; when the air conditioner is in a heating mode, the output shaft 311 of the first driving motor is matched with the first end of the air guide plate 2, when the first driving motor works, the output shaft 311 of the first driving motor drives the air guide plate 2 to rotate around the first end of the air guide plate 2, and the second end of the air guide plate 2 is separated from the second driving motor, so that air flow can be blown out obliquely downwards, and the heating effect is improved. Therefore, by arranging the driving motor 31, the air deflector 2 can automatically change the rotating shaft according to the cooling mode or the heating mode, and the driving motor 31 of the first driving assembly 3 and the driving motor 31 of the second driving assembly 4 can work without working simultaneously while ensuring that the cooling effect and the heating effect of the air conditioner can be improved, thereby reducing the energy consumption and prolonging the service life of the driving motor 31.
In some embodiments of the present invention, referring to fig. 3 to 5 in combination with fig. 7 and 9, the first end of the air deflection plate 2 and the second end of the air deflection plate 2 are respectively provided with at least one fitting portion 21, and the fitting portion 21 is formed with a fitting groove 211. For example, in the example of fig. 3 to 5, the fitting groove 211 is substantially U-shaped, and left and right ends of the fitting groove 211 penetrate left and right end surfaces of the fitting portion 21, respectively.
The first drive assembly 3 and the second drive assembly 4 further comprise a transmission 5. The transmission member 5 includes a first transmission section 51 and a second transmission section 52 connected to each other in the axial direction of the output shaft 311, the first transmission section 51 is fixedly connected to the output shaft 311, and the second transmission section 52 is detachably engaged with the engagement groove 211.
For example, with reference to fig. 3-5, the first transmission section 51 may be generally cylindrical in configuration, and the second transmission section 52 is connected to an end of the first transmission section 51 remote from the corresponding drive motor 31. When the air conditioner runs in a heating mode, the second transmission section 52 connected with the first driving motor is matched with the matching groove 211 at the first end of the air deflector 2, when the first driving motor works, the output shaft 311 of the first driving motor rotates and drives the transmission part 5 to rotate, so that the air deflector 2 is driven to rotate around the first end of the air deflector 2, the second transmission section 52 connected with the second driving motor is separated from the matching groove 211 at the second end of the air deflector 2, and air flow can be obliquely blown downwards; when the air conditioner operates in a cooling mode, the second transmission section 52 connected with the second driving motor is matched with the matching groove 211 at the second end of the air deflector 2, when the second driving motor works, the output shaft 311 of the second driving motor rotates and drives the transmission part 5 to rotate, so that the air deflector 2 is driven to rotate around the second end of the air deflector 2, the second transmission section 52 connected with the first driving motor is separated from the matching groove 211 at the first end of the air deflector 2, and air flow can be blown out horizontally forwards or obliquely upwards. Therefore, the transmission piece 5 can well transmit the torque of the output shaft 311, so that the air deflector 2 can rotate around the first end of the air deflector 2 or the second end of the air deflector 2, and the structure is simple and the processing is convenient.
Further, as shown in fig. 3 to 5, 7 and 9, the fitting portion 21 is formed with an opening 212 communicating with the fitting groove 211, the second transmission section 52 is adapted to be fitted into the fitting groove 211 through the opening 212 or separated from the fitting groove 211 through the opening 212, and the width of the opening 212 is gradually reduced in a direction toward the center of the fitting groove 211. So set up, opening 212 can play fine guide effect to can reduce the cooperation required precision to cooperation groove 211 and second transmission section 52, make second transmission section 52 can cooperate or break away from the cooperation with cooperation groove 211 smoothly, avoid cooperation portion 21 and second transmission section 52 to produce the interference.
Alternatively, referring to fig. 3, the outer circumferential surface of the second transmission section 52 includes two planar portions 521 parallel to each other, one end of the two planar portions 521 adjacent to the fitting portion 21 is connected with a connecting portion 522, and the thickness of the connecting portion 522 is gradually reduced in a direction toward the fitting portion 21.
For example, in the example of fig. 3, the connection portion 522 may be formed in an arc-shaped structure. The inner wall of the mating groove 211 may include two mutually parallel planar wall sections and a curved wall section connected between one ends of the two planar wall sections adjacent to the mating portion 21. Wherein, two plane portions 521 of the second transmission section 52 are respectively matched with two plane wall portions, and the connecting portion 522 is matched with the arc wall portion. Therefore, by arranging the two plane parts 521, the second transmission section 52 can be prevented from rotating relatively when being matched with the matching groove 211, so that the rotation of the air deflector 2 is more reliable; by providing the connecting portion 522, the connecting portion 522 can provide a good guiding function, so that the second transmission section 52 can be smoothly engaged with or disengaged from the engaging groove 211.
In some alternative embodiments of the present invention, as shown in fig. 3, 4, 7 and 9, a plurality of limiting members 6 are disposed on the machine body 1, each limiting member 6 is disposed on a side of the second transmission segment 52 away from the engaging portion 21, and the limiting members 6 cover a portion of the engaging portion 21. In the description of the present invention, "a plurality" means two or more.
For example, in the example of fig. 3, 4, 7, and 9, the limiting member 6 is formed in a C-shaped structure in which the opening 212 faces the transmission member 5, and the limiting member 6 may be disposed coaxially with the transmission member 5 and the driving motor 31. When the second transmission section 52 is matched with the matching groove 211, the limiting piece 6 covers the second transmission section 52 and a part of the matching part 21, so that the swinging generated in the rotation process of the transmission piece 5 is avoided, and the rotation of the air deflector 2 is more stable; when the second transmission section 52 is separated from the matching groove 211, the matching portion 21 is disengaged from the limiting member 6, and the limiting member 6 only covers a portion of the second transmission section 52. From this, through setting up foretell a plurality of locating parts 6, locating part 6 can play fine support limiting displacement, makes the rotation of aviation baffle 2 more reliable and more stable, can promote the structural stability of whole air conditioner indoor unit 100, and simple structure, and easily processing is favorable to using widely.
