An embodiment of the present invention provides an air conditioning indoor unit, fig. 1 is a schematic structural view of the air conditioning indoor unit according to an embodiment of the present invention, fig. 2 is a schematic structural exploded view of the air conditioning indoor unit according to an embodiment of the present invention, and fig. 3 is a schematic sectional view of the air conditioning indoor unit according to an embodiment of the present invention. The air conditioning indoor unit 1 of the present invention includes an annular casing 10, a heat exchanger 20, and an airflow driving device 30.
The axis of the annular casing 10 extends in the front-rear direction. Specifically, the annular casing 10 has an inner contour line and an outer contour line, each of which is a closed annular curve having a preset shape formed by one rotation in a vertical plane along respective predetermined paths about an axis in the front-rear direction. The outer and inner contours of the annular housing 10 may be annular, elliptical-like, heart-shaped, or other shaped, graceful, closed ring. The shape of the outer contour of the annular housing 10 may be the same as or different from the shape of the inner contour thereof. Also, the ring-shaped casing 10 has an air inlet grill 110 located at a rear side thereof and distributed along a circumferential direction thereof, and a ring-shaped air outlet 120 located at a front side thereof and distributed along a circumferential direction thereof. The indoor air flow can enter the annular casing 10 through the air inlet grille 110, and the air flow in the annular casing 10 can be sent to the indoor through the annular air outlet 120. The air inlet grille 110 is formed with a plurality of air inlets uniformly distributed along the circumferential direction of the annular casing 10. The air inlet grille 110 is preferably in the form of a closed ring, with the ring-shaped air inlet grille 110 being distributed over the entire circumferential casing wall of the annular casing 10. In some alternative embodiments, the air inlet grille 110 may also be semi-closed curved, such as a dome shape, distributed over a partial section of the circumferential casing wall of the annular casing 10.
The air conditioner indoor unit 1 is provided with the annular shell 10, so that the whole air conditioner indoor unit 1 is in a unique annular shape, the annular air conditioner indoor unit 1 is attractive and unique and is novel, and the air conditioner indoor unit can be used as an ornament especially for a desktop air conditioner indoor unit placed on a desktop. Meanwhile, the annular air outlet is formed in the front side of the indoor unit of the air conditioner, 360-degree wide-angle air supply is achieved, the air supply range is enlarged, local air flow impact is avoided, and comfort experience of a user is improved.
Fig. 4 is a schematic structural view of a heat exchanger according to an embodiment of the present invention assembled with a condensed water collecting device, and fig. 5 is a schematic structural view of a heat exchanger according to another embodiment of the present invention. The heat exchanger 20 is disposed inside the annular casing 10, and has a plurality of arc-shaped heat exchange sections 25 distributed at intervals along the circumferential direction of the annular casing 10, i.e., a gap is formed between two adjacent arc-shaped heat exchange sections 25. The heat exchanger 20 is configured to exchange heat with the air flowing through each of its arcuate heat exchange sections 25 so as to be changed into a heat exchanged air flow having a higher temperature (when the air conditioning indoor unit is heating) or a lower temperature (when the air conditioning indoor unit is cooling). The shape enclosed by the plurality of arc-shaped heat exchange sections 25 matches the shape of the annular housing 10. For example, when the annular casing 10 is in a circular shape, the shape surrounded by the plurality of arc-shaped heat exchange sections 25 may be a circular shape; when the annular casing 10 is elliptical, the shape surrounded by the plurality of arc-shaped heat exchange sections 25 may be elliptical.
The airflow driving device 30 is disposed inside the annular casing 10, and is configured to cause a portion of the airflow entering the annular casing 10 through the air inlet grille 110 to flow through the plurality of arc heat exchange sections 25 to flow to the annular air outlet 120 after heat exchange, and to cause another portion of the airflow entering the annular casing 10 through the air inlet grille 110 to flow to the annular air outlet 120 directly through a gap between two adjacent arc heat exchange sections 25. That is, only a part of the air flow entering the annular housing 10 through the air inlet grille 110 is subjected to heat exchange through each arc-shaped heat exchange section 25 of the heat exchanger 20 under the driving action of the air flow driving device 30, and the other part of the air flow directly flows through the gap between two adjacent arc-shaped heat exchange sections 25 without heat exchange. The heat-exchanged air flow and the natural air flow which is not heat-exchanged are both blown to the annular air outlet 120, and are mixed near the annular air outlet 120 to form mixed air flow. When the mixed air flows are blown to the human body, the effects of cooling, not cooling, heating and not heating can be achieved, and the softness and the comfort of air supply of the air conditioner indoor unit 1 are improved. In addition, the invention does not need to additionally design a mixed flow structure, and can realize good mixed flow effect only by the structural design of the heat exchanger 20, and has simple structure and lower cost.
In some embodiments of the present invention, the heat exchanger 20 includes a refrigerant tube 21 enclosing a closed loop or semi-closed arc along the circumference of the loop casing 10, and a plurality of heat exchange fin groups penetrating the refrigerant tube 21, and two adjacent heat exchange fin groups are spaced apart, each heat exchange fin group includes a plurality of heat exchange fins 22 closely arranged, so that each heat exchange fin group and the refrigerant tube section where it is located form an arc heat exchange section 25, thereby simplifying the structure of the heat exchanger 20.
In some alternative embodiments of the present invention, each arcuate heat exchange section of the heat exchanger 20 may also be a separate heat exchange unit, each having separate refrigerant tubes and heat exchange fins, and the two heat exchange units being connected in spaced relation.
The outline of the refrigerant tube is also illustrated in fig. 4 and 5. In some embodiments of the present invention, referring to fig. 4, the contour line of the refrigerant tube 21 forms a first arc-shaped curve N, and the refrigerant tube 21 extends from the refrigerant inlet end 211 to the refrigerant outlet end 212 along the circumferential direction of the first arc-shaped curve N. Each heat exchange fin 22 is a plate fin extending in the radial direction of the heat exchanger 20. The outline of the refrigerant tube 21 referred to in the present invention means a general shape of the refrigerant tube 21 as a whole. That is, the heat exchanger 20 employs a plurality of coils of refrigerant tubes, each coil extends along the first arc-shaped curve N, and each coil has a notch. Each circle of refrigerant pipes simultaneously penetrate through all the heat exchange fins 22, and each heat exchange fin 22 is penetrated by all circles of refrigerant pipes. At this time, the heat exchanger 20 is an arc-shaped heat exchanger, which is matched with the shape of the annular casing 10. For example, when the annular casing 10 is in the shape of a circular ring, the heat exchanger 20 may be a circular arc-shaped heat exchanger; when the annular housing 10 is elliptical, the heat exchanger 20 may be an elliptical arc heat exchanger. Since the axis of the annular casing 10 extends in the front-rear direction, the axis of the heat exchanger 20 also extends in the front-rear direction, and the heat exchanger 20 also has an inner contour and an outer contour, both of which are semi-closed arc-shaped curves in a vertical plane.
In other embodiments of the present invention, referring to fig. 5, the contour line of the refrigerant tube 21 is an annular curve M, and the refrigerant tube 21 extends from the refrigerant inlet end 211 to the refrigerant outlet end 212 along the annular curve M. Each heat exchange fin 22 is a plate fin extending in the radial direction of the heat exchanger 20. That is, the heat exchanger 20 employs a plurality of coils of refrigerant pipe, each coil extending substantially along the annular curve M. At this time, the heat exchanger 20 is an annular heat exchanger, which is an annular shape matching the shape of the annular casing 10. For example, when the annular casing 10 is in the shape of a circle, the heat exchanger 20 may be a circular heat exchanger; when the annular housing 10 is elliptical, the heat exchanger 20 may be an elliptical annular heat exchanger. Since the axis of the annular casing 10 extends in the front-rear direction, the axis of the heat exchanger 20 also extends in the front-rear direction, and the heat exchanger 20 also has an inner contour and an outer contour, both of which are closed annular curves in a vertical plane.
In still other embodiments of the present invention, the refrigerant tube 21 may also extend from the refrigerant inlet end 211 to the refrigerant outlet end 212 along the first arc-shaped curve or the annular curve in an S-shaped track. At this time, each heat exchange fin 22 is an arc fin concentric with the heat exchanger 20. That is, the projection of each heat exchange fin 22 in the basic plane perpendicular to the central axis of the first arc-shaped curve or the annular curve is an arc coaxial with the first arc-shaped curve or the annular curve, and the projections of the plurality of heat exchange fins 22 of the same arc-shaped heat exchange section 25 in the basic plane are sequentially arranged from inside to outside along the radial direction of the first arc-shaped curve or the annular curve. That is, the heat exchanger 20 employs a serpentine refrigerant tube.
Since the casing of the indoor unit 1 of the air conditioner of the present invention adopts an original ring shape, the present invention also adopts the heat exchangers 20 extending or distributed along the circumferential direction of the ring-shaped casing 10 in order to improve heat exchange efficiency and simplify the structure. However, in operation, condensed water is produced in each section of the heat exchanger 20 and drops downwardly under its own weight. Therefore, condensate collection is not negligible, and also is one of the design difficulties and emphasis for such shaped enclosures and arcuate heat exchangers.
To this end, in some embodiments of the present invention, the ring-shaped air conditioner indoor unit 1 further includes a condensed water collecting device 80 for collecting condensed water generated on each section of the heat exchanger 20, which is capable of collecting condensed water generated on each section of the heat exchanger 20 and discharging the condensed water to the outside of the ring-shaped casing 10, thereby avoiding potential safety hazards caused by the condensed water dropping onto a lower section or other components of the heat exchanger 20 or remaining at the bottom of the casing.
Fig. 6 is a schematic structural exploded view of a condensed water collecting device according to an embodiment of the present invention. Further, the condensed water collecting device 80 includes an upper water receiving tray 81, a lower water receiving tray 82, and a water guide pipe 83. The upper water receiving tray 81 is disposed inside the upper half of the heat exchanger 20 in the circumferential direction of the heat exchanger 20 for collecting condensed water generated from the upper half of the heat exchanger 20. The lower water receiving tray 82 is disposed at an outer side of the lower half of the heat exchanger 20 in a circumferential direction of the heat exchanger 20 to collect at least condensed water generated at the lower half of the heat exchanger 20. The water guide pipe 83 communicates the upper and lower water receiving trays for guiding the condensed water collected by the upper water receiving tray 81 to the lower water receiving tray 82 so as to be directly or indirectly discharged to the outside of the ring-shaped casing 10 through the lower water receiving tray 82.
The separation surface of the upper half and the lower half of the heat exchanger 20 is a plane passing through the geometric center of the annular casing 10 and extending in the horizontal direction. The inside of a certain component (e.g. heat exchanger 20) means its side close to the geometric center of the annular housing 10, and correspondingly the outside of a certain component (e.g. heat exchanger 20) means its side remote from the geometric center of the annular housing 10.
Specifically, in some embodiments, the heat exchanger 20 is an annular arcuate heat exchanger. Therefore, the contour line of the upper water pan 81 is substantially in the shape of an upwardly convex semicircle, and the contour line of the lower water pan 82 is substantially in the shape of a downwardly convex semicircle.
Therefore, the condensed water generated by the upper half part of the heat exchanger 20 drops onto the upper water receiving disc 81 positioned on the inner side of the heat exchanger 20 under the action of the gravity of the condensed water, the condensed water generated by the lower half part of the heat exchanger 20 drops onto the lower water receiving disc 82 positioned on the outer side of the heat exchanger 20 under the action of the gravity of the condensed water, and the condensed water collected on the upper water receiving disc 81 is guided to the lower water receiving disc 82 through the water guide pipe 83, so that the annular shell 10 is discharged, and potential safety hazards caused by the fact that the condensed water generated by the upper half part of the heat exchanger 20 drops onto the lower half part or other parts of the lower part or stays at the bottom of the annular shell 10 are avoided.
In some embodiments of the present invention, the condensed water collecting device 80 further includes a drain pipe 84 which communicates the lower drip tray 82 with the outer space of the annular casing 10 to drain the condensed water on the lower drip tray 82 to the outside of the annular casing 10.
Specifically, the bottom of the lower drip tray 82 has a drain hole 821 for draining condensed water therein, and a drain pipe 84 is connected to the drain hole 821 and extends to the outside of the annular casing 10 by being bent backward under the lower drip tray 82. Thus, the drain pipe 84 can be hidden at the rear side of the annular casing 10, so as to facilitate the appearance of the annular air conditioner indoor unit 1 to be attractive.
In some embodiments of the present invention, the end of the upper water receiving tray 81 has a water collecting groove 811 at the outside to allow condensed water received by the upper water receiving tray 81 to be collected in the water collecting groove 811 along the outer surface 81a thereof. A through hole 812 is formed in the bottom wall of the water collecting tank 811, and the upper end of the water guide pipe 83 communicates with the through hole 812 to allow condensed water in the water collecting tank 811 to flow into the water guide pipe 83 through the through hole 812, and thus to flow to the lower water receiving tray 82 through the water guide pipe 83.
Further, the water guide pipe 83 extends downward from the upper end to the rear side of the heat exchanger 20 in a backward bent manner, and extends downward to the inner surface 82a of the lower water pan 82 vertically or obliquely at the rear side of the heat exchanger 20 so as to be hidden at the rear side of the heat exchanger 20, so that the appearance of the indoor unit 1 of the air conditioner is improved.
Fig. 7 is a schematic cross-sectional view of the upper water pan taken along section line X-X in fig. 6. In some embodiments of the present invention, any of the sections of the upper drip tray 81 taken in the radial direction thereof has an arc-shaped curve S convexly curved toward the inside thereof. That is, the upper drip tray 81 extends in the front-rear direction along an arc-shaped curve S protruding toward the inside thereof. In other words, the outer surface of the upper drip tray 81 for receiving the condensed water is a curved surface recessed toward the geometric center of the upper drip tray 81, thereby facilitating collection of the condensed water without structural interference with the front inner case 142.
Further, the arc-shaped curve S may be a circular arc-shaped curve, and the diameter of the circle on which the circular arc-shaped curve is located may be any value ranging from 30 to 45mm, for example, 30mm, 33mm, 36mm, 39mm, 42mm or 45mm.
Fig. 8 is a schematic cross-sectional view of the lower drip tray and the drain tube taken along section line Y-Y in fig. 6. In some embodiments of the present invention, any cross section of the lower drip tray 82 taken in the radial direction thereof is a curve convexly curved toward the outside thereof, the curve including a middle circular arc section 822 and two inclined straight line sections 823 symmetrically connected to the front and rear sides of the middle circular arc section 822. The lower drip tray 82 having the inclined straight line section has a larger inclination angle and slope than the drip tray having a circular arc-shaped cross section, and the flow rate of condensed water thereon is faster, so that the condensed water can be collected and discharged more quickly. Since the lower drip tray 82 is outside the heat exchanger 20, it is not considered to interfere with the structure of the front inner case 142.
Further, the ratio between the length of each straight line section 823 and the diameter of the circle in which the middle circular arc section 822 is located is any ratio ranging from 1:1 to 1:2, for example, 1:1, 1:1.3, 1:1.5, 1:1.7, 1:1.9 or 1:2, so as to further facilitate the collection of condensed water.
Therefore, the invention can improve the collecting speed and the flowing speed of the condensed water on the upper water receiving disc 81 and the lower water receiving disc 82 as much as possible on the premise of avoiding the structural interference by specially designing the shapes of the upper water receiving disc 81 and the lower water receiving disc 82, thereby improving the collecting and discharging efficiency of the condensed water.
In some embodiments of the present invention, the number of the water guide pipes 83 may be two, and both ends of the upper water receiving tray 81 are respectively communicated with the lower water receiving tray 82 through the two water guide pipes 83. Each end of the upper drip tray 81 is provided with a water collecting trough 811.
In some embodiments of the present invention, the heat exchanger 20 further includes an inner tube plate (not shown) disposed inside the heat exchange fins 22 and an outer tube plate (not shown) disposed outside the heat exchange fins 22, between which the refrigerant tubes 21 are supported, the outer tube plate being connected to the annular housing 10. Specifically, the outer tube plate may be fastened to the rear housing 143 by screws or other suitable means. The upper water pan 81 is connected to the inner tube plate and the lower water pan 82 is connected to the outer tube plate. The upper water pan 81 and the inner tube plate, and the lower water pan 82 and the outer tube plate may be fastened by screws or other suitable means.
In some embodiments of the present invention, the annular casing 10 includes an annular front outer casing 141, an annular front inner casing 142, and an annular rear casing 143. It is understood that the axes of the rear case 143, the front inner case 142, and the front outer case 141 all extend in the front-rear direction. The front inner case 142 is disposed inside the front outer case 141 with a gap left between the front inner case 142 and the case wall of the front outer case 141. Fig. 9 is a schematic structural view of a rear case according to an embodiment of the present invention. The rear case 143 has an inner side edge portion 1432 and an outer side edge portion 1433 extending in the circumferential direction thereof. It is emphasized that "inner side" here means a side closer to the center thereof in the radial direction of the rear case 143, and correspondingly "outer side" here means a side farther from the center thereof in the radial direction of the rear case 143. The rear side of the front inner case 142 is connected to an inner side edge portion 1432 of the rear case 143, and the rear side of the front outer case 141 is connected to an outer side edge portion 1433 of the rear case 143, so that an accommodating space is defined between the rear case 143, the front inner case 142, and the front outer case 141, in which the heat exchanger 20 and the airflow driving device 30 are installed.
Specifically, the front inner case 142 and the rear case 143, and the front outer case 141 and the rear case 143 may be coupled by a snap fit, screw connection, or other suitable means. Further, airtight seals are formed between the mating interfaces of the front inner case 142 and the rear case 143, and between the mating interfaces of the front outer case 141 and the rear case 143, to prevent the air flow within the annular casing 10 from leaking to the indoor environment through other locations than the annular air outlet 120. For example, sealing rings may be provided between the mating interfaces of the front inner case 142 and the rear case 143, and between the mating interfaces of the front outer case 141 and the rear case 143.
Further, the front inner case 142 and the front outer case 141 each have front side edges extending in their respective circumferential directions, and the annular air outlet 120 is formed between the front side edges of the front inner case 142 and the front outer case 141. The air inlet grill 110 is formed on the rear housing 143.
Further, the case wall of the rear case 143 extends from the inner side edge thereof to the outer side edge thereof convexly rearward in the radial direction of the rear case 143. That is, the rear case 143 is generally annular tubular, and the front side of the annular tubular is provided with an annular opening extending in the circumferential direction thereof, the outer side edge of the annular opening forming the outer side edge of the rear case 143, and the inner side edge of the annular opening forming the inner side edge of the rear case 143. The air inlet grill 110 is opened in a region of the housing wall of the rear housing 143 that protrudes rearward most.
The present invention further defines the annular casing 10 to include three parts, namely, a front outer casing 141, a front inner casing 142 and a rear casing 143, which are all annular, and defines the annular air outlet 120 and an annular accommodating space for accommodating the heat exchanger 20 and the airflow driving device 30 through the positional layout and connection relationship between the front outer casing 141, the front inner casing 142 and the rear casing 143, which are very simple in structure and assembly, and simplifies the structural cost and labor cost.
Specifically, the front side edges of the front inner case 142 and the front outer case 141 may each have a circular shape, and the center of the circle in which the front side edge of the front inner case 142 is located may coincide with the center of the circle in which the front side edge of the front outer case 141 is located, so that the widths of the respective sections of the annular air outlet 120 in the radial direction thereof are the same. The radius of the circle in which the front side edge of the front inner case 142 is located is smaller than the radius of the circle in which the front side edge of the front outer case 141 is located.
In some embodiments of the present invention, the center of the annular casing 10 defines a center hole 130 that is opened front and back to form a negative pressure in the center hole 130 when the air flow driving device 30 drives the air supply, so that natural air in the room, which is not subjected to heat exchange, is jetted from the rear to the front through the center hole 130 and mixed with the air flow after heat exchange, which is sent out through the annular air outlet 120. That is, the center ring hole 130 in the middle of the annular casing 10 penetrates the annular casing 10 in the front-rear direction, and any part may not be placed in the center ring hole 130. The air flow after heat exchange is sent out from the annular air outlet 120 under the driving of the air flow driving device 30, at this time, negative pressure is formed in the outer periphery of the annular air outlet 120 and the central ring hole 130, and natural air behind the indoor unit 1 of the air conditioner is jetted out from the back to the front through the negative pressure area of the central ring hole 130 and is mixed with the air flow after heat exchange sent out from the annular air outlet 120. When the mixed air flows are blown to the human body, the effects of cooling, not cooling, heating and not heating can be achieved, and the softness and the comfort of air supply of the air conditioner indoor unit 1 are improved.
It can be seen that the opening at the rear side of the central ring hole 130 forms a non-heat exchange wind (i.e., natural wind) inlet, the opening at the front side of the central ring hole 130 forms a non-heat exchange wind outlet, and the annular air outlet 120 surrounds the non-heat exchange wind outlet, so that the air flow after heat exchange sent out by the annular air outlet 120 is uniformly mixed with the natural wind sent out by the non-heat exchange wind outlet, and the comfort experience of the user is further improved.
In some embodiments of the present invention, the front inner housing 142 extends from back to front along a first curve 150. Fig. 10 is a schematic structural view of a first curve according to one embodiment of the present invention. The first curve 150 includes a first section 151 and a second section 152 which are sequentially disposed from the rear to the front and smoothly connected, and the first section 151 and the second section 152 are separated along a dotted line in fig. 10. The first section 151 is a circular arc curve, and the center of the circle where the first section 151 is located outside the first section 151. That is, the first section 151 is a circular arc curve protruding toward the inside of the inner case 142, on one hand, the size of the accommodating space in the annular case 10 can be increased to facilitate the installation of the heat exchanger 20 and the air flow driving device 30, and on the other hand, the central annular hole 130 can be gradually widened from the rear to the front, i.e., the cross-sectional area of the central annular hole 130 cut out along a plane perpendicular to the front-rear direction is gradually increased from the rear to the front, so that the air flow is diffused after flowing through the central annular hole 130, thereby promoting the mixing between the non-heat exchange air flow sent out through the central annular hole 130 and the heat exchange air flow sent out through the annular air outlet 120, improving the mixing effect, and further expanding the air supply range.
Further, the second section 152 may be a straight line; the second section 152 may also be a circular arc curve, where the center of the circle where the second section 152 is located inside the second section 152, that is, the second section 152 is a circular arc curve protruding toward the outside of the inner housing 142. Further, the second section 152 extends a much smaller length than the first section 151.
In some embodiments of the present invention, the front outer case 141 extends from rear to front along the second curve 160. Fig. 11 is a schematic structural view of a second curve according to an embodiment of the present invention. The second curve 160 includes a third section 161 and a fourth section 162 which are sequentially disposed from the rear to the front and smoothly connected, and the third section 161 and the fourth section 162 are separated along a dotted line in fig. 11. The third section 161 is a circular arc curve, and the center of the circle where the third section 161 is located inside the third section 161. That is, the third section 161 is a circular arc curve protruding toward the outside of the front outer case 141, thereby being matched with the first section 151 of the front inner case 142, further increasing the size of the receiving space of the annular case 10, and also improving the external aesthetic effect of the annular case 10.
Further, the fourth section 162 may be a straight line; the fourth section 162 may also be a circular arc curve, and the center of the circle where the fourth section 162 is located outside the fourth section 162, that is, the fourth section 162 is a circular arc curve protruding toward the inside of the outer housing 142. Further, the fourth section 162 extends a length substantially less than the length of the third section 161. Thus, the fourth section 162 may form a constriction portion with a rapidly reduced cross-sectional area on the inner side of the annular air outlet 120 in cooperation with the second section 152 of the front inner housing 142, so as to increase the air outlet speed of the annular air outlet 120.
In some embodiments of the present invention, the airflow driving device 30 is a closed annular ion wind generating device extending along the circumferential direction of the annular casing 10. The annular ion wind generating device is used for promoting indoor air to enter the annular casing 10 through the annular air inlet grille 110 and flow towards the annular air outlet 120 after heat exchange through the heat exchanger 20. Specifically, the annular ion wind generating apparatus ionizes air in the annular housing 10 under high pressure to generate a large number of charged particles, which are directionally moved by the electric field force to form ion wind. Since the working principle of the ion wind generating device itself is easily available to those skilled in the art, the description thereof will not be repeated here.
The invention utilizes the annular ion wind generating device to generate a large amount of charged particles under high pressure, and the charged particles move under the action of electric field force to generate kinetic energy, thereby forming ion wind, having natural wind sense, realizing mute air supply and reducing the noise when the air conditioner indoor unit 1 operates.
In alternative embodiments of the present invention, the airflow driving device 30 may also include a plurality of small axial flow fans or other types of fans distributed along the circumference of the annular casing 10.
In some embodiments of the present invention, the indoor unit 1 further includes an annular purifying module 40, and the annular purifying module 40 is disposed in the airflow direction in the annular casing 10, for performing purifying operations such as dust removal and sterilization on the airflow flowing to the annular air outlet 120.
Further, the heat exchanger 20, the airflow driving device 30, and the annular purifying module 40 are disposed in the annular casing 10 in this order from the back to the front. Thereby, the ring-shaped ion wind generating device generates ion wind under high pressure while possibly additionally generating harmful gas such as ozone, which can be absorbed or adsorbed by the ring-shaped purification module 40 before being fed into the room, thereby enhancing the purification effect.
In alternative embodiments, the heat exchanger 20, the airflow driving device 30, and the annular purifying module 40 may be arranged in other orders within the annular housing 10. For example, the heat exchanger 20 may be disposed between the airflow driving device 30 and the annular purge module 40.
In some embodiments of the present invention, the air conditioning indoor unit 1 is a desk top air conditioning indoor unit. The bottom of the ring-shaped casing 10 has a flat surface so as to be placed directly on the table top. In some embodiments, the indoor unit 1 may also include a base 70 disposed below the annular casing 10 for supporting the annular casing 10.
When the indoor unit 1 of the air conditioner is a desktop indoor unit of the air conditioner, the heights of the annular air outlet 120 and the central ring hole 130 are just in the middle of the height of a human body, so that the defects of long heating and refrigerating time caused by rising hot air flow and sinking cold air flow in refrigeration in the traditional air conditioner heating process are overcome.
It should be understood by those skilled in the art that, unless specifically stated otherwise, terms such as "inner", "outer", "transverse", "front", "rear", etc. used in the embodiments of the present invention are used to indicate directions or positional relationships with reference to the actual use state of the indoor unit 1, and these terms are merely for convenience of description and understanding of the technical solution of the present invention, and do not indicate or imply that the device or component to be referred to must have a specific direction, and therefore should not be construed as limiting the present invention.
By now it should be appreciated by those skilled in the art that while a number of exemplary embodiments of the invention have been shown and described herein in detail, many other variations or modifications of the invention consistent with the principles of the invention may be directly ascertained or inferred from the present disclosure without departing from the spirit and scope of the invention.
