Detailed Description
To make the objects, technical solutions and advantages of the present disclosure more apparent, embodiments of the present disclosure will be described in detail with reference to the accompanying drawings.
An air conditioning indoor unit is an important component of an air conditioning system, and is generally placed in an indoor use.
In the related art, an air conditioner indoor unit mainly includes a casing, an evaporator, and a fan, both of which are located in the casing. When the indoor unit of the air conditioner works, the fan operates to suck return air in the room, and the return air is blown out again after heat exchange of the evaporator, so that the indoor temperature is adjusted. Currently, there is an air conditioning system in which a fresh air blower and a fresh air duct are separately provided in an indoor unit of an air conditioner, thereby achieving a fresh air function.
However, the air conditioning indoor unit is additionally provided with the fresh air fan and the fresh air duct, so that the size of the air conditioning indoor unit is increased, and the structure is complex.
In order to solve the above technical problem, an embodiment of the present disclosure provides an air conditioning indoor unit, where fig. 1 is a schematic structural diagram of the air conditioning indoor unit, and fig. 1 shows a partial structure of the air conditioning indoor unit by using a dotted line. Referring to fig. 1, in the present embodiment, the air conditioning indoor unit includes a casing 1, a blower 2, a first valve assembly 3a, and a second valve assembly 3 b.
The casing 1 has an air duct inside, and the surface thereof is provided with an air outlet 11, a fresh air inlet 121 and a circulating air inlet 122 which are respectively communicated with the air duct. The fan 2 is positioned in the air duct and used for driving air flow of the air duct. The first valve component 3a is positioned at the fresh air inlet 121 and used for opening or closing the fresh air inlet 121, and the second valve component 3b is positioned at the circulating air inlet 122 and used for opening or closing the circulating air inlet 122.
The fresh air inlet 121 is used for inputting outdoor air into the air duct inside the housing 1, and the circulating air inlet 122 is used for inputting indoor air into the air duct inside the housing 1. The opening or closing of the fresh air inlet 121 and the circulating air inlet 122 is controlled by the first valve component 3a and the second valve component 3b respectively, so as to realize the switching of the working modes of the indoor unit of the air conditioner.
When the indoor unit of the air conditioner is in an indoor circulation mode, the first valve component 3a controls the fresh air inlet 121 to be closed, the second valve component 3b controls the circulating air inlet 122 to be opened, indoor air enters the air channel in the shell 1 through the circulating air inlet 122 under the action of the fan and is output through the air outlet 11, and indoor circulation is completed. When the indoor unit of the air conditioner is in a fresh air circulation mode, the first valve component 3a controls the fresh air inlet 121 to be opened, the second valve component 3b controls the circulating air inlet 122 to be closed, and outdoor air enters the air channel in the shell 1 through the fresh air inlet 121 and is output through the air outlet 11 under the action of the fan, so that fresh air circulation is completed. When the indoor unit of the air conditioner is in a mixed circulation mode, the first valve component 3a controls the fresh air inlet 121 to be opened, the second valve component 3b controls the circulating air inlet 122 to be opened, and under the action of the fan, both outdoor air and indoor air enter the air channel in the shell 1 and are output from the air outlet 11, so that mixed circulation is completed.
That is to say, the three working modes all share the same fan and share the air duct in the casing 1, so that the size and the structure of the indoor unit of the air conditioner are effectively controlled.
In addition, when the indoor unit of the air conditioner stops working, the first valve component 3a controls the fresh air inlet 121 to be closed, and the second valve component 3b controls the circulating air inlet 122 to be closed, so as to prevent impurities from entering the air duct in the casing 1.
From the foregoing, the air conditioning indoor unit can switch between the multiple operation modes, because the opening or closing of the fresh air inlet 121 and the circulating air inlet 122 is controlled by the first valve component 3a and the second valve component 3b respectively. The first valve component 3a and the second valve component 3b will be described below.
Fig. 2 is a schematic structural view of the first valve component 3a and the second valve component 3b, and in order to show the assembling relationship between the first valve component 3a and the second valve component 3b and the housing 1, a part of the housing 1 is shown in fig. 2.
Referring to fig. 2, in the present embodiment, the first valve component 3a and/or the second valve component 3b includes: a transmission mechanism 31, a driving mechanism 32 and a door 33.
The driving mechanism 32 is used for providing power and has a rotating shaft 321, and the rotating shaft 321 is used for outputting power. The door 33 is movably disposed at the fresh air inlet 121 and/or the circulating air inlet 122, and the shape and size of the door 33 are matched with those of the fresh air inlet 121 and/or the circulating air inlet 122. The transmission mechanism 31 includes an input end and an output end, the input end of the transmission mechanism 31 is connected with the rotating shaft 321, the output end of the transmission mechanism 31 is connected with the door body 33, and the transmission mechanism 31 is used for transmitting the power output by the driving mechanism 32 to the door body 33, so that the door body 33 can reciprocate.
In the above implementation manner, the driving mechanism 32 is used for providing power, the transmission mechanism 31 is used for transmitting power, and the door 33 is attached to the inner wall of the casing 1 and is used for moving relative to the casing 1 under the driving of the transmission mechanism 31, so as to open or close the fresh air inlet 121 and/or the circulating air inlet 122. For example, when the orthographic projection of the fresh air inlet 121 and/or the circulating air inlet 122 on the plane where the door body 33 is located in the door body 33, the fresh air inlet 121 and/or the circulating air inlet 122 is closed by the door body 33, and at this time, the fresh air inlet 121 and/or the circulating air inlet 122 is closed. When the orthographic projection of the fresh air inlet 121 and/or the circulating air inlet 122 on the plane where the door body 33 is located is at least partially positioned outside the door body 33, the fresh air inlet 121 and/or the circulating air inlet 122 are opened. It is easily understood that, as the door 33 moves, the opening degree of the fresh air inlet 121 and/or the circulating air inlet 122 changes.
Optionally, the transmission 31 comprises a first crank 311 and a second crank 312. The first end of the first crank 311 is pivotally connected to the first end of the second crank 312, the second end of the first crank 311 is connected to the rotating shaft 321 of the driving mechanism 32, and the second end of the second crank 312 is pivotally connected to the door 33. The pivot axis between the first crank 311 and the second crank 312, the rotation axis between the first crank 311 and the rotating shaft 321 of the driving mechanism 32, and the pivot axis between the second crank 312 and the door 33 are all perpendicular to the moving direction of the door 33.
The first crank 311, the second crank 312, and the door body 33 together constitute a crank slider mechanism. During operation, the rotating shaft 321 of the driving mechanism 32 rotates to sequentially drive the first crank 311 and the second crank 312 to rotate, and since the door 33 is movably connected with the inner wall of the casing 1 and the moving track is a straight line, the rotation of the first crank 311 and the second crank 312 is converted into the reciprocating linear movement of the door 33 relative to the casing 1.
Illustratively, the reciprocating linear movement of the door 33 can be realized in two ways, one way is realized by the forward rotation and the reverse rotation of the rotating shaft 321 of the driving mechanism 32, in which case the rotating shaft 321 of the driving mechanism 32 rotates at most half a turn. The other is that the rotating shaft 321 of the driving mechanism 32 rotates a whole circle, which is realized by using the characteristic of a crank-slider mechanism. The first mode is suitable for the case of compact space, and the second mode is suitable for the case of abundant space, and two implementation modes can be selected according to actual needs, and the disclosure does not limit this.
In other embodiments, the transmission mechanism 31 may also be a rack-and-pinion mechanism, for example, the transmission mechanism 31 includes a gear and a rack, the gear is engaged with the rack, the gear is coaxially connected with the rotating shaft 321 of the driving mechanism 32, the rack is connected with the door 33, the rack is movably connected with the inner wall of the housing 1, and the moving direction of the rack is the same as the moving direction of the door 33.
In the above implementation manner, during operation, the rotating shaft 321 of the driving mechanism 32 rotates to drive the gear to rotate, so that the driving rack drives the door 33 to move together. The reciprocating linear movement of the door 33 is realized by controlling the rotation shaft 321 of the drive mechanism 32 to rotate forward and backward.
Illustratively, the driving mechanism 32 is a stepping motor, so that the stepping motor is utilized to realize accurate control of the moving distance of the door 33, and further realize accurate control of the opening degrees of the fresh air inlet 121 and the circulating air inlet 122.
With continued reference to fig. 2, in the present embodiment, the inner wall of the housing 1 has a support frame 13 and a limit frame 14. The supporting frame 13 is located at the bottom edge of the fresh air inlet 121 and/or the circulating air inlet 122, the limiting frame 14 is located at the top edge of the fresh air inlet 121 and/or the circulating air inlet 122 and is opposite to the supporting frame 13, the door body 33 is located between the supporting frame 13 and the limiting frame 14, and the door body 33 is respectively connected with the supporting frame 13 and the limiting frame 14 in a sliding mode.
The support frame 13 supports the door body 33, so that an installation space is provided for the door body 33, the limiting frame 14 limits the door body 33, and the door body 33 is prevented from falling. Under the action of the supporting frame 13 and the limiting frame 14, the door 33 can stably move between the supporting frame 13 and the limiting frame 14, and the stability of the first valve component 3a and the second valve component 3b is ensured.
Optionally, since the support frame 13 is located at the bottom edge of the fresh air inlet 121 and/or the circulating air inlet 122, in order to avoid the support frame 13 blocking the air flow in the fresh air inlet 121 and/or the circulating air inlet 122, an orthographic projection of the support frame 13 on the plane where the fresh air inlet 121 and/or the circulating air inlet 122 is located does not coincide with the fresh air inlet 121 and/or the circulating air inlet 122. Further, in order to ensure the support of the door 33, the length of the support bracket 13 in the moving direction of the door 33 is greater than the maximum moving distance of the door 33. The limiting frame 14 is similar to the supporting frame 13, and will not be described herein.
Fig. 3 is a partial schematic view of a portion a of fig. 2, and with reference to fig. 3, in this embodiment, the supporting frame 13 has a first sliding chute 131, the first sliding chute 131 extends along a moving direction of the door body 33, a notch of the first sliding chute 131 faces the limiting frame 14, and at least a portion of the door body 33 is movably located in the first sliding chute 131.
In the above implementation manner, the bottom of the door 33 is inserted into the first chute 131, and through the first chute 131, not only is the guidance of the door 33 realized, but also the door 33 is prevented from coming off from the support frame 13.
Fig. 4 is a partial schematic view of a portion B in fig. 2, and with reference to fig. 4, in the present embodiment, the limiting frame 14 has a second sliding groove 141, the second sliding groove 141 extends along the moving direction of the door body 33, a notch of the second sliding groove 141 faces the supporting frame 13, and at least a portion of the door body 33 is movably located in the second sliding groove 141.
In the above implementation manner, the top of the door 33 is inserted into the second sliding groove 141, and through the second sliding groove 141, not only is the guidance of the door 33 achieved, but also the door 33 is prevented from coming off from the support frame 13. That is, the door 33 is sandwiched between the support frame 13 and the limiting frame 14, and the bottom and the top of the door 33 are limited and guided by the first sliding chute 131 and the second sliding chute 141, respectively, so that the door 33 slides stably.
It is easily understood that since the first and second sliding chutes 131 and 141 each extend in the moving direction of the door body 33, the first and second sliding chutes 131 and 141 are parallel to each other.
Optionally, the outer edge of the door body 33 has a sealing strip 331, and the sealing strip 331 is sandwiched between the door body 33 and the inner wall of the casing 1. By the design, the sealing performance of the door body 33 on the fresh air inlet 121 and/or the circulating air inlet 122 can be ensured, so that the problem of air leakage after the fresh air inlet 121 and/or the circulating air inlet 122 are closed is avoided.
The valve assembly 3 has been described above and the housing 1 and fan 2 are described below.
Referring to fig. 1 again, in the present embodiment, the circulating air inlet 122 is located at the top of the casing 1, the air outlet 11 is located at the bottom of the casing 1, and the fresh air inlet 121 is located at the side of the casing 1.
That is to say, the circulating air inlet 122, the fresh air inlet 121 and the air outlet 11 are respectively located on the wall of the casing 1, so that the circulating air inlet 122, the fresh air inlet 121 and the air outlet 11 are ensured not to be affected with each other, especially, the opening and closing of the circulating air inlet 122 and the fresh air inlet 121 are realized by the first valve component 3a and the second valve component 3b corresponding to each other, and the controllability of the indoor unit of the air conditioner is improved.
Illustratively, the housing 1 is a rectangular parallelepiped structural member including six housing walls, respectively a top wall, a bottom wall, a front wall, a rear wall, a left wall, and a right wall. During the assembly, the back wall is installed on the wall, and the roof is towards the roof, and the diapire is towards ground, and circulated air inlet 122 is located the roof, and new trend inlet 121 is located left wall or right wall, and air outlet 11 is located the diapire. It is easy to understand that the fresh air inlet 121 is communicated with the outside through a pipeline, so that fresh air outside can enter the air channel in the casing 1 through the fresh air inlet 121.
With continued reference to fig. 1, optionally, the air inlet port of the blower 2 is close to the top of the housing 1, and the air outlet port of the blower 2 is close to the bottom of the housing 1.
In the above implementation manner, the fan 2 is located in the middle of the housing 1, the air inlet port of the fan 2 is close to the top of the housing 1 so as to communicate with the circulating air inlet 122 and the fresh air inlet 121, and the air outlet port of the fan 2 is close to the bottom of the housing 1 so as to communicate with the air outlet 11.
Illustratively, the fan 2 is a crossflow fan.
Fig. 5 is a schematic configuration diagram of an air conditioning system according to an embodiment of the present disclosure, and with reference to fig. 5, the air conditioning system includes an indoor air conditioning unit 100, a throttling device 200, a condenser 300, and a compressor 400, where the indoor air conditioning unit 100 is the indoor air conditioning unit 100 shown in fig. 1 to 4, and the indoor air conditioning unit 100, the throttling device 200, the condenser 300, and the compressor 400 are sequentially connected.
In the above implementation manner, the heat exchange medium of the air conditioning system is freon, and enters the evaporator of the indoor unit 100 of the air conditioner after passing through the throttling device 200, so that the evaporator of the indoor unit 100 of the air conditioner can absorb heat, thereby reducing the air temperature of the air duct in the casing 1, and under the action of the fan 2, the air in the air duct in the casing 1 and the air in the external space of the casing 1 perform convection, thereby adjusting the ambient temperature of the indoor unit 100 of the air conditioner.
Since the air conditioning system includes the indoor air conditioning unit 100 shown in fig. 1 to 4, the air conditioning system has all the advantages of the indoor air conditioning unit 100, and will not be described herein again.
The above description is intended to be exemplary only and not to limit the present disclosure, and any modification, equivalent replacement, or improvement made without departing from the spirit and scope of the present disclosure is to be considered as the same as the present disclosure.
