Description

Technical Field

[0001] The present invention relates to the technical field of air conditioning, and in particular to an indoor unit of an air conditioner. Background Art

[0002] The appearance of existing cabinet air conditioners is not significantly different, and the experience is not good based on the existing air supply method, resulting in many complaints from users. When using air conditioning for cooling, users often encounter a set of contradictory problems: low air outlet temperature and high wind speed, which makes people feel uncomfortable, that is, people often say that the wind is too "hard" and not soft enough. Combining user pain points and industry development trends, a soft wind experience feature is proposed. Research has found that if a portion of indoor air can be mixed into the cold air of the air conditioner, the temperature of the air flow will rise by 1°-3° after mixing, and the feeling of blowing on people will also be softer and more comfortable.

[0003] Although some existing air conditioners also achieve soft wind effect through diversion, the air supply direction of the soft wind is relatively fixed. The soft wind supply mode cannot meet the shortcomings of users with different air supply needs living in the same room, the wide-angle air supply angle is small, and the partitioned soft wind delivery cannot be achieved.

[0019] Optionally, the air induction space only includes an air inlet section and an air outlet section connected to each other;

[0020] The width of the air outlet section gradually increases along the flow direction of the airflow; the width of the air inlet section gradually decreases along the flow direction of the airflow;

[0021] The second edge is the front end of the air outlet section.

[0022] Optionally, the air outlet portion is a vertically arranged air outlet column, and the cross-sectional areas of the two air outlet columns are equal or unequal;

[0023] The air outlet is provided on the front side of each of the air outlet columns;

[0044] The present invention provides an indoor unit of an air conditioner. The indoor unit of the air conditioner is the indoor part of a split air conditioner and is used to adjust the indoor air, such as cooling / heating, dehumidifying, introducing fresh air, etc. The indoor unit of the air conditioner can be a conventional floor-standing cabinet unit or a wall-mounted unit.

[0045] Figure 1 is a schematic front view of an air conditioner indoor unit according to an embodiment of the present invention, with reference to Figures 2 to 6 The indoor unit of the air conditioner according to the embodiment of the present invention comprises an air outlet, an air guide device 20 and an air guide body 30. The front side of the air outlet has an air outlet 15 extending in the length direction of the air outlet. The two edges of the air outlet 15 extending in the length direction are respectively a first edge and a second edge. The surface of the air outlet comprises an air guide area connected to the first edge. The edge of the air guide area arranged opposite to the first edge is a third edge. The air guide device 20 has an air outlet state of guiding the air outlet 15 to discharge air toward the front side of the air outlet 15, and an air guide state of forming a first air guide surface connected to the second edge and defining a connecting gap with the first edge. The edge of the first air guide surface away from the second edge is a fourth edge. The gap between the third edge and the fourth edge is an air outlet gap. The air guide body 30 is movably arranged at the front side of the air guide area, and the air guide body 30 has a closed state of closing the air outlet gap, and an open state of opening part or all of the air outlet gap.

[0046] When the wind guide device 20 is in the wind outlet state, the wind from the wind outlet 15 can be guided to blow toward the front side of the wind outlet 15. When the wind guide device 20 is in the wind outlet state, a connecting gap is formed in front of the wind outlet 15, and the wind from the wind outlet 15 passes through the connecting gap, enters the channel formed by the wind guide area and the first wind guide surface, and blows out from the wind outlet gap. The wind guide body 30 is movable, and can close the wind outlet gap, close the wind from the wind outlet 15, and can also open part or all of the wind outlet gap. In particular, when the wind guide body 30 partially opens the wind outlet gap, the wind guide body 30 also plays a role in adjusting the direction of the wind passing through the wind outlet gap, so that the wind outlet angle of the wind outlet portion can be increased.

[0047] In some embodiments of the present invention, there are two air outlet portions, two air guide devices 20 and two air guide bodies 30, one air outlet portion is located on a lateral side of the other air outlet portion, and the air outlet 15 corresponding to one air outlet portion is located on a lateral side of the air outlet 15 corresponding to the other air outlet portion.

[0048] Furthermore, in some embodiments of the present invention, the two air outlets are spaced apart to form an air induction gap 16 between the two air outlets. When the two air outlets 15 discharge air forward, the air in the air induction gap 16 is driven forward by negative pressure, so that the air is mixed with the air blown out from the two air outlets 15, thereby increasing the air output.

[0049] In some embodiments of the present invention, each air outlet 15 faces forward of each other. Each air outlet interval faces forward.

[0050] In some embodiments of the present invention, each air guide 30 can be moved to multiple positions. For example, part or all of each air guide 30 can be moved to a position in front of the corresponding first air guide surface; and / or part of each air guide 30 can be moved to a position in front of the air guide gap 16; and / or two air guides 30 can be moved to a position in front of the air guide gap 16 in contact with each other to close the air guide gap 16.

[0051] In some embodiments of the present invention, when part or all of each air guide body 30 can be moved to the position in front of the corresponding first air guide surface, the air guide body 30 is spaced apart from the corresponding fourth edge. The air guide body 30 is spaced apart from the corresponding fourth edge, and when the corresponding air outlet 15 discharges air, the air in the air induction interval 16 can be driven to flow through the interval and mixed with the air discharged from the air outlet 15 to increase the air volume.

[0052] Furthermore, in some embodiments of the present invention, each air guide body 30 slides laterally. The surface of the air guide body 30 facing the air guide area is a second air guide surface, and two lateral edges of the second air guide surface are a fifth edge and a sixth edge, respectively, and the fifth edge is located in front of the sixth edge and close to the third edge.

[0053] The air guide body 30 slides horizontally and cooperates with the air guide device 20 at different positions to have different air supply modes. Figure 2 As shown, the air guide body 30 closes the air outlet gap, the air guide body 30 contacts the third edge, and the second air guide surface contacts the fourth edge. In this position, the two air outlets do not discharge air through the air outlet gap. Figure 3 As shown, when the air guide body 30 closes the air outlet interval, the air guide device 20 can guide each air outlet 15 to discharge air in front of each other, and under the action of negative pressure, guide the air in the air induction interval 16 to mix, thereby increasing the air output and making the wind feel soft and comfortable. Figure 4 As shown, during the lateral sliding of the air guide 30, a gap appears between the air guide 30 and the fourth edge, especially when the two air guides 30 move to a position where they contact each other to close the front side of the air guide gap 16, when each air guide device 20 guides the air from the corresponding air outlet 15 in a direction away from the other air outlet, under the action of negative pressure, the air in the air guide gap 16 passes through the gap between each air guide 30 and the corresponding fourth edge and merges into the air blown out from the corresponding air outlet 15, thereby increasing the air volume. In other words, Figure 4 The arrangement shown enables the air outlet to increase the air outlet volume while significantly increasing the air outlet angle.

[0054] When the two air guide bodies 30 move respectively, Figure 5 As shown, both air outlets 15 blow air to the left, wherein the air guide body 30 on the left side is in a position that moves to the front side of the air induction interval 16, and the air guide body 30 on the right side closes the corresponding air outlet interval. When the air is discharged, the air from the air outlet 15 on the left side drives the air in the air induction interval 16 to pass through the interval between the air guide body 30 and the corresponding fourth edge, and mixes with the air from the air outlet 15 on the left side, and finally mixes with the air from the air outlet 15 on the right side. Figure 6 As shown, both air outlets 15 blow air to the right, wherein the air guide body 30 on the right side is in a position moved to the front side of the air induction interval 16, and the air guide body 30 on the left side closes the corresponding air outlet interval. When the air is discharged, the air discharged from the right air outlet 15 drives the air in the air induction interval 16 to pass through the interval between the air guide body 30 and the corresponding fourth edge, and mixes with the air discharged from the right air outlet 15, and finally mixes with the air discharged from the right air outlet 15. The above arrangement enables the air outlet to introduce the air in the air induction interval 16 even if the air outlet guides the air to one side, thereby increasing the air output. Figure 5 and Figure 6 The mode shown may be referred to as a one-sided soft wind mode. Figure 3 The mode shown can be called the aggregated soft wind mode, Figure 4 The mode shown can be called wide-angle soft wind mode. Matching intelligent control logic can be used to intelligently identify and customize wind sensations, that is, the air supply mode can be automatically set according to user needs.

[0055] In some embodiments of the present invention, the air inlet interval 16 only includes an air inlet section and an air outlet section connected to each other. The width of the air outlet section gradually increases along the flow direction of the air flow. The width of the air inlet section gradually decreases along the flow direction of the air flow. The above-mentioned arrangement of the air inlet interval 16 is conducive to the air entering the rear side of the air inlet interval 16 and is also conducive to the air in the air inlet interval 16 flowing forward.

[0056] In some embodiments of the present invention, the second edge is a front end of the air outlet section.

[0057] In some embodiments of the present invention, the air outlet is a vertically arranged air outlet column 10, and the cross-sectional areas of the two air outlet columns 10 are equal or unequal. An air outlet 15 is provided on the front side of each air outlet column 10. In particular, when the cross-sectional areas are unequal, the two air outlet columns 10 present a large and a small air outlet column 10, which has a unique appearance.

[0058] In some embodiments of the present invention, the two air outlets are symmetrically arranged with respect to a reference plane, the two air guide devices 20 are symmetrically arranged with respect to a reference plane, and the two air guide bodies 30 are symmetrically arranged with respect to a reference plane.

[0059] In some embodiments of the present invention, the third edge is located obliquely in front of the first edge and away from the other third edge. This arrangement is conducive to the air outlet interval to discharge air forward.

[0060] In some embodiments of the present invention, the wind guide device 20 includes at least one wind guide plate, and preferably, the wind guide device 20 includes two wind guide plates. The two wind guide plates extend along the extension direction of the air outlet 15, and the two wind guide plates are rotatable.

[0061] In some embodiments of the present invention, an air inlet 13 connected to an air outlet 15 is provided on the side wall of each air outlet column 10. A fan is provided in each air outlet column 10, and the fan guides air into the air outlet column 10 and blows it out from the air outlet 15. The fan is a cross-flow fan 14. A heat exchanger 12 is provided in at least one air outlet column 10. When one of the two air outlet columns 10 blows a heat exchange airflow, the heat exchange airflow, the non-heat exchange airflow and the air in the induced draft interval 16 are mixed in front of the air conditioner indoor unit, so that the temperature of the mixed airflow is closer to the room temperature, thereby making the air outlet soft. When both air outlet columns 10 blow a heat exchange airflow, the heat exchange airflow and the air in the induced draft interval 16 are mixed in front of the air conditioner indoor unit, which also makes the air outlet soft.

[0062] In some embodiments of the present invention, an electric heater 11 is provided in each air outlet column 10 for heating the air entering the air outlet column 10 in a controlled manner.

[0063] At this point, those skilled in the art should recognize that, although multiple exemplary embodiments of the present invention have been shown and described in detail herein, many other variations or modifications that conform to the principles of the present invention can still be directly determined or derived based on the content disclosed in the present invention without departing from the spirit and scope of the present invention. Therefore, the scope of the present invention should be understood and recognized as covering all these other variations or modifications.
