Detailed Description
An air conditioning indoor unit 10 according to an embodiment of the present invention is described below with reference to fig. 1 to 9. Where the terms "front", "back", "upper", "lower", "inner", "outer", "lateral", etc., indicate orientations or positional relationships that are based on the orientation or positional relationships shown in the drawings, this is for convenience in describing the invention and to simplify the description, and does not indicate or imply that the referenced device or element must have a particular orientation, be constructed and operated in a particular orientation, and thus should not be construed as limiting the invention.
Fig. 1 is a schematic view of an external configuration of an air conditioning indoor unit 10 according to an embodiment of the present invention, fig. 2 is a schematic view of an internal configuration of the air conditioning indoor unit 10 according to an embodiment of the present invention, in which a front panel 12 is hidden to show an internal configuration of the indoor unit 10, and fig. 3 is a schematic structural view of a drain pan 16 of the air conditioning indoor unit 10 according to an embodiment of the present invention.
The indoor air conditioner 10 of this embodiment is a wall-mounted indoor air conditioner, and includes a casing having an air intake area formed on both lateral sides thereof, two heat exchangers 13 and two air supply fans disposed inside the corresponding air intake area 11a in the accommodating space inside the casing. The housing is further formed with two outlets, one outlet being formed at the upper portion of the front side of the housing and denoted as an upper outlet 12a, and the other outlet being formed at the lower portion of the front side of the housing and denoted as a lower outlet 12 b. Wherein the front-back direction is the direction as shown in fig. 1.
The heat exchanger 13 exchanges heat with air flow entering the shell through the air inlet area 11a to form heat exchange air flow, the temperature difference between the temperature of the air flow entering the shell and the surface temperature of the heat exchanger 13 is large, condensate water is easy to form on the surface of the heat exchanger 13, and the condensate water formed by the heat exchanger 13 can be received through a water receiving disc 16 arranged at the bottom of the heat exchanger 13, so that the condensate water is prevented from being leaked.
For this reason, the air conditioning indoor unit 10 of this embodiment further includes two water-receiving trays 16, where the two water-receiving trays 16 correspond to the two heat exchangers 13 one by one, and are located at the bottom of the corresponding heat exchanger 13 in the accommodating space inside the casing, and are used for receiving the condensed water formed by the corresponding heat exchanger 13. A drain opening 16a is formed in the bottom of each drip pan 16, and the drain opening is connected to a drain pipe through which the condensed water received in the drip pan 16 is drained.
As shown in fig. 3, the water pan 16 is shaped like a long boat extending forward and backward, and can receive more condensed water to prevent the condensed water from overflowing, and when the indoor unit 10 is not suspended properly, the condensed water is prevented from overflowing due to being discharged from the water discharge port 16 a.
The projection of the shell on the vertical plane bearing the air-conditioning indoor unit 10 is circular, and the projections of the upper air outlet 12a and the lower air outlet 12b on the vertical plane are both circular, so that the whole air-conditioning indoor unit 10 is unique and attractive in appearance, is completely different from the existing long-strip-shaped wall-mounted air-conditioning indoor unit 10, and meets the individual aesthetic requirements of users.
The lateral direction (which may also be referred to as a left-right direction) is the direction indicated in fig. 2. In some embodiments, the two air inlet regions 11a are symmetrically distributed with respect to the longitudinal center line of the casing, so as to further enhance the aesthetic appearance of the indoor unit 10.
As shown in fig. 2, the projection of each heat exchanger 13 on the vertical plane carrying the indoor unit 10 of the air conditioner is arc-shaped and is consistent with the bending direction of the corresponding air inlet area 11a, so as to increase the air inlet area, reduce the air inlet resistance and improve the heat exchange efficiency of the heat exchanger 13. The circle centers of the arc-shaped heat exchangers 13 can coincide with the circle center of the shell, and the two heat exchangers 13 are symmetrically distributed relative to the vertical center line of the shell, so that the size of the heat exchangers 13 is ensured, and sufficient residual space can be provided for the arrangement of an air supply fan and other components in the shell.
In some embodiments, the maximum value of the transverse distance dimension between the heat exchanger 13 and the corresponding air inlet area 11a is in a range of 30 to 40 mm, and the size of the heat exchanger 13 is enough to cover the position opposite to the air inlet area 11a, so as to ensure the heat exchange efficiency of the heat exchanger 13.
One of the two blower fans is configured to cause a part of the air flow to flow from the air intake area 11a toward the upper portion of the accommodating space so that the part of the air flow is blown out from the upper air outlet 12a, and the other blower fan is configured to cause a part of the air flow to flow from the air intake area 11a toward the lower portion of the accommodating space so that the part of the air flow is blown out from the lower air outlet 12 b.
The air-conditioning indoor unit 10 with the similar appearance in the existing scheme is provided with the air outlet and the air supply fan, so that the air supply requirement of the air-conditioning indoor unit 10 is met, the power of the air supply fan is large, the size of the air-conditioning indoor unit 10 is large, the whole thickness (the size of the air-conditioning indoor unit 10 in the front-back direction) of the air-conditioning indoor unit 10 is large, the air outlet is formed in the flat surface of the front side of the indoor unit 10, and the whole attractiveness of the indoor unit 10. In the embodiment, the air-conditioning indoor unit 10 with a circular appearance is completely improved, air supply of the air-conditioning indoor unit 10 is realized by adopting two air supply fans, the two air supply fans are relatively small in size, the accommodating space in the shell can be more reasonably distributed, and the overall volume and thickness of the air-conditioning indoor unit 10 can be greatly reduced; in addition, the upper air outlet 12a is formed at the upper part of the front side of the shell, the lower air outlet 12b is formed at the lower part of the front side of the shell, and the upper air outlet 12a and the lower air outlet 12b are mutually set off, so that the appearance of one air outlet is prevented from being abrupt visually, the overall appearance of the indoor unit 10 is more harmonious and beautiful, and the higher aesthetic requirements of users are met.
In addition, because the indoor unit 10 has two independent air supply fans and two independent air outlets, the states of the two air supply fans can be controlled according to the operation mode of the indoor unit 10 to control the air outlet position, thereby achieving better heating/cooling effect and improving air supply comfort. For example, in the cooling mode, the blowing fan that causes part of the airflow to flow to the upper portion of the accommodating space in the casing may be controlled to be turned on, and under the action of the blowing fan, the cool air flows to the upper portion and is blown out forward through the upper outlet 12a, while the other blowing fan (the blowing fan that causes part of the airflow to flow to the lower portion of the accommodating space in the casing) remains turned off, and the cool air is blown out forward only from the upper outlet 12a, thereby raising the cool air outlet position and avoiding discomfort of the user caused by the cool air blowing downward and directly to the user. Because cold wind has the trend of sinking, make cold wind upwards blow as far as possible, promote refrigeration effect, and avoid cold wind directly to blow the human body and influence user's refrigeration and experience.
During the mode of heating, steerable messenger's part air current is opened to the air supply fan that accommodation space lower part flows in the casing, and another air supply fan (messenger's part air current is closed to the air supply fan that accommodation space upper portion flows in the casing), and hot-blast air only blows out forward from lower air outlet 12b, has reduced hot-blast air-out position, avoids hot-blast rising and leads to indoor lower part space temperature in time to rise, influences user's heating experience. Because hot air has an ascending trend, the hot air is blown downwards as much as possible, so that the temperature of the upper space and the temperature of the lower space in the room are uniform, and the heating effect and the heating experience of a user are improved.
In some embodiments, the housing includes a rear case 11 with an open front side and a front panel 12 located at the front side of the rear case 11 and forming a receiving space with the rear case 11, and accordingly, the rear case 11 and the front panel 12 are both circular in projection on a vertical plane carrying the indoor unit 10. The rear case 11 is formed with the above-mentioned air intake area 11a, the above-mentioned upper outlet 12a is formed on the upper portion of the front panel 12, and the above-mentioned lower outlet 12b is formed on the lower portion of the front panel 12.
In some embodiments, the diameter of the upper outlet 12a is equal to the diameter of the lower outlet 12b, and the ratio of the diameter of the upper outlet 12a to the diameter of the housing ranges from 0.2: 1 to 0.3: 1, for example, the ratio of the diameter size of the upper air outlet 12a to the diameter size of the housing is 0.26. In some embodiments, the upper outlet 12a and the lower outlet 12b are symmetrically distributed with respect to the transverse center line of the casing, and the upper outlet 12a and the lower outlet 12b are designed to be circular and symmetrically distributed, so as to meet the aesthetic standards of the public and further increase the aesthetic appearance and harmony of the indoor unit 10.
In some embodiments, the range of the ratio of the distance between the central point of the upper outlet 12a and the central point of the lower outlet 12b to the diameter of the housing is 0.6: 1 to 0.75: for example, the ratio of the distance between the center point of the upper outlet 12a and the center point of the lower outlet 12b to the diameter of the housing is 0.66. The positions and the sizes of the upper outlet 12a and the lower outlet 12b are designed in such a way that the sizes and the positions of the upper outlet 12a and the lower outlet 12b can be more harmoniously matched with the overall size of the front panel 12, thereby further increasing the aesthetic appearance and the harmony of the indoor unit 10.

Each air outlet pipe 18 comprises an outer pipe 181 extending front and back and a first inner pipe 182 connected to the inner peripheral wall of the outer pipe 181 and extending to the front side of the outer pipe 181 in a gradually expanding manner from back to front, the air inlet end of the first inner pipe 182 is located at a position close to the front end of the outer pipe 181 in the outer pipe 181, the air outlet end of the first inner pipe 182 protrudes from the front side of the corresponding air outlet, and a first spacing space 103 is formed between the inner peripheral wall of the outer pipe 181 and the inner peripheral wall of the first inner pipe 182, that is, the first inner pipe 182 is in a horn-shaped structure from back to front, the outer pipe 181 and the first inner pipe 182 form a returning pipe, part of heat exchange air flow can flow forward through the inner space of the first inner pipe 182, and part of heat exchange air flow can flow forward. Therefore, the air outlet range is enlarged, and a better air supply effect is realized.
In some embodiments, each of the outlet pipes 18 further includes a second inner pipe 183, the second inner pipe 183 is extended from the rear to the front in the corresponding first inner pipe 182, and a second spacing space 104 is formed between the outer peripheral wall of the second inner pipe 183 and the inner peripheral wall of the corresponding first inner pipe 182. The heat exchange air flowing to the upper part of the housing accommodating space enters the outer pipe 181 and is divided into three parts, part of the heat exchange air flows through the space in the second inner pipe 183 and is blown out forwards, part of the heat exchange air flows through the first partition space 103 and is blown out forwards, and part of the heat exchange air flows through the second partition space 104 and is blown out forwards; the heat exchange wind flowing toward the lower portion of the housing accommodating space is also divided into three portions into the outer pipe 181 and blown out toward the front side. Therefore, the air flow is blown forward more dispersedly, and the air supply uniformity and comfort are further improved.
In this embodiment, each air outlet pipe 18 is designed into the above-mentioned square-wave structure, so that the air outlet range can be increased, and a wide-area air supply effect can be realized; and the heat exchange airflow is diffused to the front side of the air outlet corresponding to the indoor unit 10, and the sucked ambient air flows forwards, so that the air supply uniformity is further improved, the air is softer and more natural, and the user feels cool but not cold when blowing the air onto the body, and the comfort of the user is improved.
The first inner tube 182 is connected to the inner peripheral wall of the outer tube 181 by a bracket (not shown in fig. 9), and the second inner tube 183 is connected to the inner peripheral wall of the first inner tube 182 by another bracket (not shown in fig. 9), which plays a role of fixing the first inner tube 182 and the second inner tube 183, and has a small size, thereby preventing the air flow from being blocked. For example, a plurality of first connecting rods (not shown) are spaced apart from the outer circumferential wall of the first inner tube 182 in the circumferential direction, and constitute the bracket, and the first inner tube 182 is fixed to the outer tube by the plurality of first connecting rods spaced apart from each other. Correspondingly, a plurality of second connecting rods (not shown) are distributed on the peripheral wall of the second inner tube 183, and the plurality of second connecting rods form the other bracket, and the second inner tube 183 is fixed on the first inner tube 182 through the plurality of second connecting rods distributed at intervals.
In the embodiment where the air supply fan is a single-suction centrifugal fan, the air inlet ends of the two air outlet pipes 18 (i.e., the air inlet ends of the outer pipes 181) pass through the corresponding air guide outlets 15b of the air guide sleeve 15 and are located in the corresponding air guide channels, so that the heat exchange air flow enters the corresponding air outlet pipes 18 through the air inlet ends of the outer pipes 181 via the air guide channels.
In the embodiment where the blower fan is an axial flow fan, it is understood that the axial flow fan (not shown) generally includes a fan housing and a wind wheel disposed in an accommodating space in the fan housing. The air inlet ends of the two air outlet pipes 18 (namely the air inlet ends of the outer pipes 181) can be sleeved on the outer peripheral wall of the fan shell of the corresponding axial flow fan.
In some embodiments, as shown in fig. 9, the inner peripheral wall of the outer tube 181 of each outlet duct 18 includes a rear wall section 181a and a front wall section 181b which are sequentially connected in the direction from the air inlet end to the air outlet end of the outer tube 181, the rear wall section 181a is a hollow truncated cone shape which is gradually expanded from the air inlet end of the outer tube 181 to the front, the front wall section 181b is a hollow truncated cone shape which is gradually expanded from the position connected to the rear wall section 181a to the air outlet end of the outer tube 181, and the taper angle 2e of the rear wall section 181a is greater than the taper angle 2c of the front wall section. It is also understood that the inner peripheral wall of the outer tube 181 is divided into two sections from the rear end to the front end of the outer tube 181, namely, a rear wall section 181a and a front wall section 181b, the rear wall section 181a is flared from the rear to the front, the front wall section 181b is flared from the rear to the front, and the rear wall section 181a is more flared than the front wall section 181 b. As shown in fig. 9, the angle e is the angle between the wall surface of the rear wall section 181a and the horizontal line extending forward and backward, and the cone angle of the rear wall section 181a is 2 e; the angle c is an included angle between the wall surface of the front wall section 181b and a horizontal line extending forward and backward, and the taper angle of the front wall section 181b is 2 c.
The air inlet end of the first inner tube 182 is positioned in the space formed by the front wall section 181b to form a first spacing space 103 between the front wall section 181b and the outer peripheral wall of the first inner tube 182, so that the air flow is ensured to enter the outer tube 181, mixed and combed in the rear wall section 181a of the outer tube 181, and then flows forwards to blow out along different flow paths, thereby reducing the eddy loss. The distances from the air inlet end of the first inner tube 182 (i.e., the rear end of the first inner tube 182) to the rear end of the front wall section 181b of the outer tube 181 are substantially the same as the distances from the front end of the front wall section 181b (i.e., the air outlet end of the outer tube 181).
In some embodiments, as shown in fig. 9, the first inner tube 182 has a hollow truncated cone shape with a uniform wall thickness gradually expanding from the air inlet end to the air outlet end, and the taper angle 2b of the first inner tube 182 is greater than the taper angle 2c of the front wall section 181b of the outer tube 181, it can also be understood that the first inner tube 182 has a flaring shape from the rear end to the front end.
In some embodiments, as shown in fig. 9, the second inner tube 183 of the outlet duct 18 extends in a diverging manner from the rear to the front inside the corresponding first inner tube 182, and it is understood that the second inner tube 183 is integrally located in the first inner tube 182, and has a trumpet shape diverging from the rear to the front, and the outer peripheral wall of the second inner tube 183 has a truncated cone shape diverging from the rear to the front. The inner peripheral wall of the second inner tube 183 is a truncated cone shape gradually expanding from the air inlet end to the air outlet end of the second inner tube 183, that is, the inner peripheral wall of the second inner tube 183 is a truncated cone shape gradually expanding from back to front. The taper angle 2d of the inner peripheral wall of the second inner tube 183 is larger than the taper angle 2a of the outer peripheral wall of the second inner tube 183, and the taper angle 2a of the outer peripheral wall of the second inner tube is equal to the taper angle 2c of the front wall section 181b of the outer tube 181.
By defining the inner peripheral wall of the outer pipe 181 as the above structure and defining the shapes of the first inner pipe 182 and the second inner pipe 183 as the above structure, the first space 103 (the space between the outer pipe 181 and the first inner pipe 182), the second space 104 (the space between the first inner pipe 182 and the second inner pipe 183) and the space in the second inner pipe 183 defined thereby split the air flow, thereby expanding the air outlet range, further reducing the eddy current loss and improving the air supply efficiency; and the air outlet is softer and more uniform.
In some embodiments, the taper angle 2c of the front wall section 181b satisfies: 0 ° <2a ≦ 2c ≦ 40 °, and the cone angle 2e of the rear wall section 181a satisfies: 0 <2e < 50, for example, the cone angle 2c of the front wall section 181b is 7.8 and the cone angle 2e of the rear wall section 181a is 46.2. In some embodiments, the taper angle 2b of the first inner tube 182 may satisfy: 20 degrees <2b is less than or equal to 80 degrees, and the taper angle 2d of the inner peripheral wall of the second inner pipe 183 can satisfy: 30 <2d < 60 °, for example, the taper angle 2b of the first inner tube 182 is 60 °, and the taper angle 2d of the inner peripheral wall of the second inner tube 183 is 45 °. The air outlet pipe 18 formed by the method can further reduce the eddy loss and improve the air supply efficiency.
In some embodiments, the outlet duct 18 can be configured to be controllably movable in the front-rear direction between a position protruding out of the front side of the outlet of the corresponding indoor unit 10 and a position retracted into the outlet of the corresponding indoor unit 10, that is, the outlet duct 18 located above is configured to be controllably movable in the front-rear direction between a position protruding out of the front side of the upper outlet 12a and a position retracted into the upper outlet 12a, and the outlet duct 18 located below is configured to be controllably movable in the front-rear direction between a position protruding out of the front side of the lower outlet 12b and a position retracted into the lower outlet 12 b.
Specifically, when the air outlet pipe 18 is controlled to retract back to the corresponding air outlet, the outer peripheral wall of the air outlet end of the first inner pipe 182 abuts against the inner peripheral wall of the corresponding air outlet to close the first partition space 103, so that the heat exchange air flow is blown out from the second inner pipe 183 to the front side, and part of the heat exchange air flow is blown out from the second partition space 104 to the front side. That is, when the air outlet pipe 18 located above is controlled to retract to the position in the upper air outlet 12a, the outer peripheral wall of the air outlet end of the first inner pipe 182 of the air outlet pipe 18 abuts against the inner peripheral wall of the upper air outlet 12a, part of the heat exchange air flow flowing to the upper portion of the housing space is blown out forward from the second inner pipe 183 of the air outlet pipe 18 located above, and part of the heat exchange air flow is blown out forward from the second partition space 104. When the lower outlet pipe 18 is controlled to retract to the position of the lower outlet 12b, the outer peripheral wall of the outlet end of the first inner pipe 182 of the outlet pipe 18 abuts against the inner peripheral wall of the lower outlet 12b, and the airflow flowing to the lower portion of the accommodating space in the housing is blown out forward from the second inner pipe 183 of the lower outlet pipe 18.
When the air outlet pipe 18 is controlled to move forward to a position protruding out of the front side of the corresponding air outlet, the air outlet end of the first inner pipe 182 protrudes out of the front side of the corresponding air outlet, because the first inner pipe 182 is gradually enlarged from back to front, it can be understood that the outer diameter of the front section of the first inner pipe 182 is larger than that of the rear section, when the air outlet pipe 18 moves forward, the air outlet end of the first inner pipe 182 is separated from the inner peripheral wall of the corresponding air outlet, and the air outlet end of the first inner pipe 182 protrudes out of the front side of the corresponding air outlet, so that the space (the first spacing space 103) between the outer wall of the first inner pipe 182 and the inner wall of the outer pipe 181 is exposed, and therefore heat exchange air flows are blown out forward in the first spacing space 103, the second spacing space.
The movement of the two outlet ducts 18 and the states of the two blower fans can be controlled according to the operation mode of the indoor unit 10. For example, in the cooling mode, the air outlet duct 18 corresponding to the upper air outlet 12a can be controlled to move to a position protruding from the front side of the upper air outlet 12a, and the blower fan for driving part of the air flow to the upper part of the accommodating space in the housing can be controlled to be turned on; the air outlet pipe 18 corresponding to the lower air outlet 12b can be kept in the lower air outlet 12b and does not move forward, accordingly, the corresponding air supply fan (namely the air supply fan which causes part of air to flow to the lower part of the accommodating space in the shell) keeps a closed state, cold air is blown forward only through the air outlet pipe 18 positioned at the upper part, the air outlet position of the cold air is raised, and discomfort of a user caused by the fact that the cold air is blown downward and directly to the user is avoided. Because cold wind has the trend of sinking, make cold wind upwards blow as far as possible, promote refrigeration effect, and avoid cold wind directly to blow the human body and influence user's refrigeration experience. In addition, because the air outlet pipe 18 positioned on the upper part moves forwards to protrude out of the front side of the upper air outlet 12a, the air supply range is expanded, the air supply uniformity is improved, and the refrigeration comfort experience of a user is further enhanced.
In the heating mode, the air outlet pipe 18 corresponding to the lower air outlet 12b can be controlled to move to a position protruding out of the front side of the lower air outlet 12b, and the air supply fan corresponding to the air outlet is controlled to be opened (i.e. the air supply fan which causes part of the air flow to the lower part of the accommodating space in the shell), while the air outlet pipe 18 corresponding to the upper air outlet 12a can be kept in the upper air outlet 12a and does not move forward, correspondingly, the air supply fan corresponding to the air outlet (i.e. the air supply fan which causes part of the air flow to the upper part of the accommodating space in the shell) keeps a closed state, hot air is blown out forward only through the air outlet pipe 18 positioned at the lower part, the hot air outlet position is lowered, and the situation that the temperature of the lower indoor. Because hot air has an ascending trend, the hot air is blown downwards as much as possible, so that the indoor upper space temperature and the indoor lower space temperature are uniform, and the heating effect and the user heating experience are improved. In addition, because the air outlet pipe 18 at the lower part moves forwards to protrude out of the front side of the lower air outlet 12b, the air supply range is expanded, the air supply uniformity is improved, and the heating comfort experience of a user is further enhanced.

The length dimension of the tooth section of the rack 102 engaged with the gear can be equal to or greater than the distance dimension between the air outlet end of the corresponding outer pipe 181 and the air outlet end of the first inner pipe 182, so as to ensure that the air outlet pipe 18 moves forward to a position where the part of the first inner pipe 182 located at the front side of the outer pipe 181 completely extends out of the air outlet corresponding to the indoor unit 10, so as to further increase the air outlet range and the air supply distance, and improve the air supply efficiency and the air outlet uniformity.
In the scheme that the two air supply fans are single-suction centrifugal fans 14, the air inlet end of the air outlet pipe 18 is in sliding contact with the inner wall of the corresponding diversion air duct, and in the process that the air outlet pipe 18 moves back and forth, the rear section of the air outlet pipe 18 is always positioned in the diversion air duct of the corresponding diversion cover 15. It can be understood that the size of the air outlet pipe 18, the size of the air guiding duct, and the size of the opening formed by the arc-shaped partition wall 154 and communicating the air collecting cavity and the air guiding duct are required to ensure that the heat exchange air can enter the air guiding duct through the air collecting cavity when the air outlet pipe 18 moves forwards or backwards.

In the scheme that the two air supply fans are axial flow fans, the air inlet ends of the two air outlet pipes 18 (namely the air inlet ends of the outer pipes 181) are in close sliding contact with the fan shell of the axial flow fan. In the forward and backward movement process of the air outlet duct 18, the rear section of the air outlet duct 18 is always sleeved on the outer peripheral wall of the fan housing of the corresponding axial flow fan, for example, in the forward or backward movement process of the air outlet duct 18, the rear sections 181a and 181b of the air outlet duct 18 are always in contact with the outer peripheral wall of the fan housing of the corresponding axial flow fan, so as to ensure the stability of the air outlet duct 18.
