The invention provides a vertical air conditioner indoor unit. The indoor unit of the vertical air conditioner is an indoor portion of a split type air conditioner for conditioning indoor air, such as cooling/heating, dehumidifying, introducing fresh air, etc. The indoor unit of the vertical air conditioner can be a conventional floor cabinet or a vertical wall-mounted unit.
Fig. 1 is a schematic front view of a floor air conditioner indoor unit according to a first embodiment of the present invention, and fig. 2 is an enlarged view of fig. 1 taken in N-N section.
As shown in fig. 1 and 2, a floor air conditioner indoor unit according to a first embodiment of the present invention may generally include a first column casing 10 and a second column casing 20.
The first column casing 10 has a vertical column shape, that is, a hollow column casing. The first column casing 10 is provided with a first air outlet 12 for blowing out the heat exchange air flow. The "heat exchange air flow" refers to an air flow which is used for adjusting the indoor temperature by completing heat exchange with the heat exchanger 17 of the air conditioner. The heat exchanger 17 is connected with a compressor, a heat exchanger of an outdoor unit, a throttling device and other refrigerating elements through pipelines to form a vapor compression refrigeration cycle system. When the indoor unit of the vertical air conditioner is in the refrigerating mode, the heat exchange airflow is cold air, and when the indoor unit of the vertical air conditioner is in the heating mode, the heat exchange airflow is hot air. The heat exchange air is blown to the indoor environment through the first air outlet 12, and refrigeration and heating of the indoor environment are completed.
The second cylindrical shell 20 is vertically cylindrical, i.e., hollow cylindrical shell. The second housing 20 is provided with a second air outlet 22 for blowing out non-heat exchanging air flow. Specifically, the non-heat exchange air flow can be one or more of indoor air, fresh air flow, purified air flow, humidifying air flow or water washing air flow, and the function of the non-heat exchange air flow is to assist in adjusting the indoor environment.
In the air conditioning field, there are some double-column vertical air conditioner indoor units, but two column shells are used for blowing out heat exchange air flow, and the form is very single. The vertical air conditioner indoor unit of the embodiment of the invention designs a second column casing 20 which is in parallel with the first column casing 10 and is specially used for blowing out non-heat exchange air flow, and the structure breaks through the convention, and is very novel and ingenious. In addition, as the heat exchanger is not required to be arranged in the second column casing 20, the second column casing 20 can be designed to be thinner, so that the second column casing 20 is obviously thinner than the first column casing 10, the asymmetric design not only just meets the air mixing requirement, but also enables the appearance of the vertical air conditioner indoor unit to be more novel and unique, and improves the competitiveness of the product in the aspect of appearance.
As shown in fig. 1 and 2, the first air outlet 12 is opened at the front side of the first column casing 10, and the second air outlet 22 is opened at the front side of the second column casing 20, so as to allow the non-heat exchange air flow to be mixed into the heat exchange air flow in front of the indoor unit of the vertical air conditioner.
The appearance difference of the existing vertical air conditioner indoor units is not obvious, and the air supply experience is poor, so that users complain. Particularly, when the air conditioner is used for refrigerating, people often feel that the air outlet temperature is low and the air speed is high, and the user is uncomfortable due to direct blowing of cold air into the human body, namely, people often say that the air is too hard and not soft enough.
In the embodiment of the invention, the indoor unit of the vertical air conditioner utilizes the first column shell 10 to blow out heat exchange air flow, and utilizes the second column shell 20 to blow out non-heat exchange air flow, wherein the non-heat exchange air flow is mixed with the heat exchange air flow in front of the indoor unit of the vertical air conditioner. When the non-heat exchange air flow is indoor air, the non-heat exchange air flow is mixed with the heat exchange air flow to form a mixed air flow, the temperature of the mixed air flow is closer to the room temperature than that of the heat exchange air flow, the comfort is higher, the wind sense is softer, the wind quantity and the wind speed are increased, and the air supply distance is longer. When the second casing 20 blows out the conditioning air flows such as fresh air flow, purified air flow, humidified air flow or water washing air flow, the conditioning air flows can be mixed with the heat exchange air flow earlier and more, the mixing rate is enhanced, and the conditioning air flows are better diffused to all parts of a room.
Further, as shown in fig. 2, the second column casing 20 and the first column casing 10 may be arranged in a lateral direction, and an induced air space 13 is formed therebetween. The front and rear of the induced air interval 13 are communicated with the indoor environment. The "lateral direction" is indicated in the figure, and the left-right direction perpendicular to the front-rear direction of the indoor unit of the floor air conditioner is the "lateral direction".
When the indoor unit of the vertical air conditioner of the embodiment of the invention operates, the first column casing 10 and the second column casing 20 can be selectively or simultaneously opened for air supply. When the first air outlet 12 and/or the second air outlet 22 are/is air-out, the indoor air in the induced air interval 13 is driven to flow forward by virtue of the negative pressure effect, so that the indoor air behind the indoor unit of the vertical air conditioner flows forward through the induced air interval 13 to be mixed into the air-out air flow of the first column casing 10 or the second column casing 20, and a drainage air-mixing effect is formed. Compared with the heat exchange air flow, the temperature of the air mixing air flow is closer to the room temperature, the comfort is higher, the wind sense is softer, the air quantity and the air speed are increased, and the air supply distance is longer. Particularly, when the second casing 20 also blows out the indoor air, the mixing amount of the indoor air is larger, the mixing speed is faster, a stronger air mixing effect can be achieved, and the airflow is closer to the room temperature.
As shown in fig. 2, the ratio of the width of the second column housing 20 in the lateral direction to the width of the first column housing 10 in the lateral direction may be made smaller than 1/2. The width refers to the distance between two points at which the outer walls of the second column casing 20 or the first column casing 10 are farthest in the lateral direction on both lateral side walls. The ratio of the depth dimension of the second column casing 20 in the front-rear direction to the depth dimension of the first column casing 10 in the front-rear direction, which is the distance between the two points at which the outer walls of the second column casing 20 or the first column casing 10 are farthest in the front-rear direction, is less than 1/2. So that the size difference between the two is large enough to form a double-column differentiated appearance. The second air outlet 22 may be flush or substantially flush with the front-to-back position of the first air outlet 12, such as not more than 5cm in front-to-back distance, for better mixing of the non-heat exchanging air stream with the heat exchanging air stream.
As shown in fig. 2, a second air duct 25 communicating with the second air outlet 22 is provided in the second casing 20 for more smoothly guiding the non-heat exchange air flow in the second casing 20 to the second air outlet 22. The distance between the two lateral side walls 251, 252 of the second air duct 25 gradually decreases from the rear to the front, and forms a tapered shape. The tapered air duct can accelerate the airflow, so that the non-heat exchange airflow can be blown out of the second air outlet 22 more quickly, and negative influence on the wind speed caused by no fan in the second casing 20 can be compensated to a certain extent.
As shown in fig. 2, the air-inducing interval 13 may be formed into a gradually-expanding shape with gradually-increasing transverse dimension from back to front, so that the air-out flows of the first air outlet 12 and the second air outlet 22 can better form negative pressure in the outlet area of the air-inducing interval 13, and the air flow of the air-inducing interval 13 is larger.
Fig. 3 is an enlarged view of fig. 2a, fig. 4 is a schematic view of the indoor unit of the air conditioner shown in fig. 2 when the indoor unit of the air conditioner is switched to the left air blowing mode, and fig. 5 is a schematic view of the indoor unit of the air conditioner shown in fig. 2 when the indoor unit of the air conditioner is switched to the right air blowing mode.
As shown in fig. 2 to 5, a second air guide member 26 for guiding the second air outlet 22 in the lateral air outlet direction is mounted on the second casing 20. By "directing the lateral air-out direction" is meant changing the angle of the air-out direction to the front-to-back direction, e.g., directing the air-out flow straight ahead, left-to-front, right-to-front, etc. In addition, a first air guide member 16 for guiding the first air outlet 12 in a lateral air outlet direction is mounted on the first column casing 10.
The vertical air conditioner indoor unit can change the included angle between the non-heat exchange air flow and the heat exchange air flow by adjusting the air outlet direction of the first air outlet 12 and/or the second air outlet 22, so as to change the intersection position of the non-heat exchange air flow and the heat exchange air flow. The vertical air conditioner indoor unit comprises a vertical air conditioner indoor unit, a heat exchange air flow and a heat exchange air flow, wherein the heat exchange air flow is arranged in the vertical air conditioner indoor unit, and the heat exchange air flow is arranged in the vertical air conditioner indoor unit. The indoor unit of the vertical air conditioner can adjust the intersection position according to the position of the human body so as to avoid the approach of the intersection position to the human body and cause discomfort to the human body.
In addition, the indoor unit of the vertical air conditioner can be further configured to adjust the lateral air outlet direction of the second air outlet 22 by using the second air guiding component 26, so that the non-heat exchange air flow can be converged into the heat exchange air flow of the first air outlet 12. That is, when the first air guiding member 16 changes the air outlet direction of the heat exchange air flow, the second air guiding member 26 is controlled to act, so as to ensure that the non-heat exchange air flow can always sink into the heat exchange air flow. For example, as shown in fig. 2, when the first wind guide member 16 swings forward, the second wind guide member 26 is caused to guide forward. As shown in fig. 4, when the first wind guide member 16 swings to the left, the second wind guide member 26 is caused to guide the left. As shown in fig. 5, when the first wind guide member 16 swings to the right, the second wind guide member 26 is caused to guide the wind to the right. The main control board of the air conditioner may be electrically connected to the motors of the second air guiding member 26 and the first air guiding member 16 at the same time, so as to control the cooperation of the two.
As shown in fig. 3, the second air guide member 26 may include a first plate 261 and a second plate 262 arranged at a lateral interval. Of course, the second plate 262 and the first plate 261 are connected by other structures, which are not illustrated in fig. 3. The end of the first plate 261, which is close to the second plate 262, has a bent portion 2611 bent backward, and an air guide channel 260, which tapers from the back to the front, is formed between the bent portion 2611 and the second plate 262. The second wind guide member 26 is rotatably mounted to the second casing 20 about the vertical axis x so as to change the lateral wind outlet direction of the second wind outlet 22 by adjusting the relative positions of the wind guide passage 260 and the second wind outlet 22.
For example, as shown in fig. 2 and 3, when the air guide passage 260 faces the second air outlet 22, the non-heat exchanging air flow is guided to blow out toward the front. As shown in fig. 4, the second air guide member 26 is rotated clockwise with respect to the state of fig. 2 such that the air guide passage 260 faces the left front so as to guide the non-heat exchange air flow to blow out toward the left front. As shown in fig. 5, the second air guide member 26 is rotated counterclockwise with respect to the state of fig. 2 so that the air guide passage 260 faces the right front so as to guide the non-heat exchange air flow to blow out toward the right front. The air guide member of this embodiment has a very simple structure and occupies a small space, and is particularly suitable for the air outlet of the second air outlet 22, which is of a narrow shape, and the design is very ingenious.
As shown in fig. 3, a second air duct 25 communicating with the second air outlet 22 may be provided in the second casing 20. One lateral side wall 251 of the second air duct 25 is provided with a receiving groove 2512, and the other lateral side wall 252 is provided with a recess 2523. When the second air guiding member 26 rotates to a lateral limit angle, the first plate 261 extends into the accommodating groove 2512, so that the air guiding surface of the bending portion 2611 is flush with the surface of the lateral sidewall 251 of the second air duct 25, as shown in fig. 4, and the air flow is more smoothly led into the air guiding channel 260 from the second air duct 25. Similarly, when the second air guiding member 26 rotates to another lateral limit angle, the second plate 262 is embedded in the recess 2523, so that the air guiding surface of the second plate 262 is flush with the surface of the lateral sidewall 252 of the second air duct 25, as shown in fig. 5.
Fig. 6 is a schematic view of the indoor unit of the stand air conditioner shown in fig. 2 when the second air outlet 22 is closed.
The second air outlet 22 may be closed by the second air guiding member 26. As shown in fig. 6, the second air guiding member 26 is rotated to a position where the first plate 261 closes the second air outlet 22, so as to close the second air outlet 22.
In some alternative embodiments, conventional rotary air deflectors may also be utilized to direct the direction of the air out of the second air outlet 22.
Fig. 7 is a partially cut-away schematic view of the vertical air conditioner indoor unit shown in fig. 1, with only the structure below the broken line being cut away in fig. 7.
As shown in fig. 7, the floor air conditioner indoor unit further includes a lower column casing 30. The lower column housing 30 is used to introduce or produce the aforementioned non-heat exchanging gas stream and then discharge the non-heat exchanging gas stream to the second column housing 20. The first column casing 10 and the second column casing 20 extend upward from the top end of the lower column casing 30. The first column casing 10 and the lower column casing 30 may be formed as an integral unit, or the second column casing 20 and the lower column casing 30 may be formed as an integral unit. The lower column casing 30 can be made to constitute the lower casing of the vertical air conditioner indoor unit, and when the vertical air conditioner indoor unit is a floor type, the bottom of the lower column casing 30 is placed on the ground. The embodiment of the invention uses the lower column casing 30 to support and fix the first column casing 10 and the second column casing 20, so that the whole structure of the vertical air conditioner indoor unit is more stable.
In addition, as shown in fig. 1, the indoor unit of the floor air conditioner may further include an upper connection case 40, and the upper connection case 40 is connected to the top ends of the first and second column cases 10 and 20. The first column casing 10 and the upper connection casing 40 may be formed as a single piece, or the second column casing 20 and the upper connection casing 40 may be formed as a single piece. By arranging the upper connecting shell 40, the structure of the indoor unit of the vertical air conditioner is firmer, and the appearance is more coordinated.
A heat exchanger 17 and a first fan 14 are provided in the first column casing 10 for producing a heat exchange air flow. More specifically, the rear side or the lateral sides of the first column casing 10 may be provided with an air inlet 11, a first air duct 15 is disposed in the first column casing 10, the first air duct 15 is communicated with the first air outlet 12, and the first fan 14 is a through-flow fan and is disposed at an inlet of the first air duct 15. Under the action of the first fan 14, indoor air flows into the first column casing 10 through the air inlet 11, exchanges heat with the heat exchanger 17 to form heat exchange air flow, then enters the first air duct 15, and is guided to the first air outlet 12 by the first air duct 15, as shown in fig. 2.
As shown in fig. 7, a lower blower 35 is provided in the lower column housing 30 for delivering the non-heat exchanging air flow to the second column housing 20. In this way, the blower can be avoided from being arranged in the second column casing 20, so that the second column casing 20 can be designed to be thinner, and the space of the lower column casing 30 can be more fully utilized.
Fig. 8 is a left side view of the indoor unit of the floor air conditioner shown in fig. 1, with parts of the lower column casing 30 and the second column casing 20 being cut away. In fig. 8, there are 3 curved broken lines, and the area between the upper and lower curved lines is a cut-away area, and the area below the broken line at the lowest position is a cut-away area.
As shown in fig. 7 and 8, the lower fan 35 may include a wind wheel 351 and a scroll casing 352, the wind wheel 351 being disposed within the scroll casing 352, the scroll casing 352 being for guiding a wind direction. The exhaust side of the scroll casing 352 communicates with the second housing 20 to exhaust the non-heat exchanging airflow toward the second housing 20. Also, the lower column casing 30 is provided with a fresh air inlet 32 and at least one indoor air inlet 31, both of which communicate with the suction side of the scroll 352. A fresh air duct 36 is connected to the fresh air inlet 32 for introducing fresh air from outside. The fresh air inlets 32 are positioned at the rear wall of the lower column casing 30, and the number of the indoor air inlets 31 is two, and the fresh air inlets are respectively positioned at the two lateral side walls of the lower column casing 30. The embodiment enables the lower fan 35 to suck fresh air flow and indoor air, thereby achieving the effect of achieving two purposes. In addition, a damper may be provided at the fresh air inlet 32 or the indoor air inlet 31 to control the opening and closing or opening thereof, thereby adjusting the intake ratio of the fresh air flow and the indoor air.
As shown in fig. 7 and 8, the downdraft fan 35 may further include a filter screen 353 disposed within the volute 352 for filtering the fresh air flow and the indoor air.
If the non-heat exchange air flow is a purified air flow, a humidified air flow or a water washing air flow, a purifying module, a humidifying module or a water washing module may be disposed in the lower column casing 30.
In some embodiments, as shown in fig. 8, the second air outlet 22 is in a vertical bar shape. A second air duct 25 in a vertical bar shape is arranged in the second casing 20 and is communicated with the second air outlet 22, a plurality of guide vanes 23 are arranged in the second air duct 25 in a vertical direction, each guide vane 23 extends from front to back, and the rear end is bent downwards to form a guide bending part 231. The non-heat exchange air flow flows from bottom to top, and after encountering each guide vane 23, is guided by the guide bent part 231 thereof, and gradually changes from upward flow to forward flow. Therefore, the diversion bending part 231 plays a role of changing the airflow direction, so that the airflow is more gently turned and the wind loss is smaller. The guide bending part 231 and the rest part of the guide vane 23 are in a rounded transition.
Further, considering that the non-heat exchange air flow enters the second casing 20 from the bottom of the second casing 20, the air outlet amount in the middle or upper portion of the second air outlet 22 may be smaller. Therefore, in the embodiment of the present invention, a plurality of vertically arranged air deflectors 23 are particularly disposed in the second casing 20, and the distance between the front end and the rear end of the air deflector 23 located higher is greater, so that the air outlet of the second air outlet 22 at each vertical position is more uniform.
Fig. 9 is a schematic front view of a floor air conditioner indoor unit according to a second embodiment of the present invention, fig. 10 is a schematic left side view of fig. 9, fig. 11 is an enlarged view of a cross section M-M of fig. 9, and fig. 12 is a schematic view of the floor air conditioner indoor unit shown in fig. 9 when both the first air guide member and the second air guide member guide air forward.
As shown in fig. 9 to 12, the second embodiment of the present invention is mainly different from the first embodiment in that the non-heat exchange air flow includes indoor air. The second air outlet 22 is provided on the front side of the peripheral wall of the second casing 20. The second air inlet 21 opened to the indoor environment is opened at other portions of the peripheral wall of the second casing 20 to introduce indoor air. A second fan 24 is disposed in the second casing 20, and the second fan 24 is configured to promote the indoor air in the second casing 20 to be blown out through the second air outlet 22, and then mixed into the heat exchange air flow blown out by the first air outlet 12, so as to form a mixing effect.
The second column casing 20 is arranged at a lateral interval from the first column casing 10 so that an induced air space 13 is formed therebetween. The front and rear of the induced air interval 13 are communicated with the indoor environment. So that when the first air outlet 12 and/or the second air outlet 22 are/is air-out, the indoor air in the air inducing space 13 is driven to flow forwards by the action of negative pressure.
When the indoor unit of the vertical air conditioner of the embodiment of the invention operates, the first column casing 10 and the second column casing 20 can be selectively or simultaneously opened for air supply. When the first air outlet 12 and/or the second air outlet 22 are/is air-out, the indoor air in the induced air interval 13 is driven to flow forward under the action of negative pressure, so that the induced air mixing effect is formed. Compared with the heat exchange air flow, the temperature of the air mixing air flow is closer to the room temperature, the comfort is higher, the wind sense is softer, the air quantity and the air speed are increased, and the air supply distance is longer. As shown in fig. 9 to 12, the second air intake 22 may be made to penetrate through the lateral side wall and the rear wall of the second casing 20 facing away from the first casing 10 so that the second air intake 21 is opened rearward and in a direction laterally away from the second casing 20 to increase the air intake range and increase the amount of intake air.
As shown in fig. 11 and 12, the second fan 24 may be a cross-flow fan whose axis is parallel to the length direction of the second casing 20. Such a vertically arranged cross-flow fan is suitable for the second air outlet 22 in the form of a vertical bar. For example, the second air outlet 22 may be an integral vertical strip extending from top to bottom, or may be an intermittent vertical strip formed by a plurality of vertically arranged sub-air outlets. In order to match with the cross-flow fan, the operation efficiency of the cross-flow fan is higher, the wind resistance is smaller, as shown in fig. 11, a second air duct 25 is formed in the second casing 20, the second air duct 25 is a cross-flow air duct, the outlet of the second air duct is communicated with the second air outlet 22, and the second fan 24 is arranged in the second air duct 25. Of course, the second fan may be an axial flow fan or a centrifugal fan, or be other types of fans, or be a cross flow fan with a horizontal axis, which are all widely used in the air conditioning field, and are not described herein.
As shown in fig. 11 to 12, the first column casing 10 is mounted with a first air guiding member 16 for guiding the first air outlet 12 in a transverse air outlet direction, and in particular, the first air guiding member 16 may each include an air guiding swing blade group having an axis extending vertically, and each swing blade is swung synchronously by a motor drive to change the wind direction. The second casing 20 is provided with an air guiding swing blade 27 for guiding the transverse air outlet direction of the second air outlet 22. In addition, the first air outlet 12 may be closed by the first air guiding component 16, and the second air outlet 22 may be closed by the air guiding swing blade 27, as shown in fig. 11.
Fig. 13 is a schematic front view of a floor air conditioner indoor unit according to a third embodiment of the present invention, fig. 14 is an enlarged view of a section C-C of fig. 13, fig. 15 is a schematic view of the floor air conditioner indoor unit shown in fig. 14 after a damper-closing induced air interval, and fig. 16 is a schematic view of the floor air conditioner indoor unit shown in fig. 15 after a second casing is rotated laterally outward.
As shown in fig. 13 to 16, the third embodiment of the present invention is mainly improved in that the indoor unit of the floor air conditioner further includes a damper 50, and the damper 50 is configured to controllably adjust the flow area of the induced air space 13 so that the flow area is increased or decreased, as compared with the first embodiment. Alternatively, the flow-through area can be set to zero, i.e. the air-inducing interval 13 is completely closed. Specifically, the damper 50 may be mounted on the lower column housing 30.
After the overflow area of the induced air interval 13 is increased, the mixing amount of indoor air is increased, the influence on the temperature of the hot air exchange flow is larger, and even if the temperature of the cold air flow is increased more, the temperature of the hot air flow is reduced more, so that the wind sense is more comfortable. This adjustment may be made when the user is particularly concerned with comfort. When the flow area of the induced air space 13 is reduced, the mixing amount of indoor air is reduced, and the influence on the temperature of the heat exchange air flow is reduced. The adjustment may be made when the user wants to be directly blown by cold/hot air to obtain a more intuitive, obvious cooling/heating sensation. Of course, the air inducing function can also be completely stopped by closing the air inducing interval 13. In short, the invention enables the indoor unit of the vertical air conditioner to have more adjusting modes by enabling the flow area of the induced air interval 13 to be adjustable.
The damper 50 may be configured to rotatably adjust the flow area of the induced gap 13 about the vertical axis x 1. The design of the rotating structure is simpler, and only the motor is required to directly drive the rotating structure. Specifically, the damper 50 may be provided at the inlet of the induced air space 13 and be in a vertically extending prismatic shape, the outer peripheral wall portion surface of which constitutes the wind shielding surface 51, and the rotation axis x1 of the damper 50 is located away from the wind shielding surface 51 and rearward of the second casing 20. The damper 50 is configured to be rotatable to a closed position such that the induced air space 13 is shielded by the wind shielding surface 51, as shown in fig. 15, or to a closed position located behind the second casing 20. In the open position, as shown in fig. 14, the damper 50 is positioned away from the air intake path of the induced draft interval 13, so that air intake is smoother. In the open position, the wind-blocking surface 51 may be directed away from the first column casing 10 (e.g., in fig. 14, the first column casing 10 is located to the right of the second column casing 20, and the wind-blocking surface 51 is directed to the right).
Further, as shown in fig. 15 and 16, the second casing 20 may be configured to be rotatably mounted to the lower casing 30 about a vertical axis to adjust the orientation of the second air outlet 12, thereby adjusting the air outlet direction of the second air outlet 12. The vertical air conditioner indoor unit can change the included angle between the non-heat exchange air flow and the heat exchange air flow by adjusting the air outlet direction of the second air outlet 12, so as to change the intersection position of the non-heat exchange air flow and the heat exchange air flow. The vertical air conditioner indoor unit comprises a vertical air conditioner indoor unit, a heat exchange air flow and a heat exchange air flow, wherein the heat exchange air flow is arranged in the vertical air conditioner indoor unit, and the heat exchange air flow is arranged in the vertical air conditioner indoor unit. The indoor unit of the vertical air conditioner can adjust the intersection position according to the position of the human body so as to avoid the approach of the intersection position to the human body and cause discomfort to the human body. In addition, when the outlet air flows of the two column casings need to be mixed with each other, the second column casing 20 may be configured to move along with the movement of the first air guiding member 16, so as to ensure that the indoor air can be mixed into the heat exchange air flow, and avoid that the two air flows flow away from each other.
In this embodiment, the second casing 20 is rotatable as a whole, and no additional air guiding structure is required to be designed at the second air outlet 22, so that the appearance of the second casing 20 is more concise.
