And each first air outlet is provided with an air guide device for adjusting an included angle between the heat exchange air flow and the flowing direction of the non-heat exchange air flow.

Optionally, the air guide devices are air guide cylinders, each air guide cylinder is rotatably arranged at one first air outlet, the peripheral wall of each air guide cylinder comprises at least two ventilation sections and one wind shielding section which are arranged along the peripheral direction of the air guide cylinder, and

Each air duct is configured to be rotatable to a position in which any one of the ventilation sections is opposed to the first air outlet to allow the air-out air to flow through the ventilation section into the air duct and then blow out through the other ventilation sections and to allow the orientation of the ventilation section for air-out to be rotationally adjusted, or to a position in which the wind-shielding section is opposed to the first air outlet to shield the first air outlet.

Optionally, each first air outlet is inclined towards the direction transversely away from the first column casing so as to open towards the inclined front, and

A movable first air deflector is arranged at each first air outlet for opening or shielding the transverse air outlet path of the first air outlet, and

The vertical air conditioner indoor unit utilizes the first column shell to blow out heat exchange air flow, utilizes the second column shell to blow out non-heat exchange air flow, and forms an induced air interval between the first column shell and the second column shell. Therefore, when the first column casing and/or the second column casing are/is air-out, a negative pressure environment is formed at the air inducing interval, so that indoor air behind the indoor unit of the vertical air conditioner is caused to flow forwards through the air inducing interval to be mixed into air-out air flow of the first column casing or the second column casing, and a drainage air mixing effect is formed.

Therefore, different ventilation sections are switched to be opposite to the first air outlet through the rotary air duct, different ventilation sections are utilized for supplying air indoors, and finally the purpose of changing the air supply effect is achieved. For example, the direction, the air outlet area and other parameters of different ventilation sections at the air supply position can be different, so that the wind direction and the air quantity are different when the ventilation sections supply air, and the structure is quite novel and ingenious.

Those of ordinary skill in the art will understand the specific meaning of the terms described above in the present invention as the case may be.

The invention provides a vertical air conditioner indoor unit. The indoor unit of the vertical air conditioner is an indoor portion of an air conditioner for conditioning indoor air, such as cooling/heating, dehumidifying, introducing fresh air, and the like. 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 an embodiment of the present invention, fig. 2 is an enlarged view of an N-N section of fig. 1, fig. 3 is a schematic view when the floor air conditioner indoor unit shown in fig. 2 is switched to an aggregate air supply mode, and fig. 4 is a schematic view when the floor air conditioner indoor unit shown in fig. 2 is switched to a surrounding air supply mode. Fig. 3 shows the flow direction of the heat exchange air flow by solid arrows, and the flow direction of the indoor air by open arrows.

As shown in fig. 1 to 4, an indoor unit of a floor air conditioner embodying the present invention may generally include a first column casing 10 and a second column casing 70.

The first column casing 10 is vertically columnar, and is provided with two first air outlets 11, 12 arranged side by side in the transverse direction at the front side thereof for blowing out heat exchange air flow. 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 is in a refrigerating mode, the heat exchange airflow is cold air. When the vertical air conditioner indoor unit is in a heating mode, the heat exchange airflow is hot air. The heat exchange air flows through the first air outlets 11 and 12 and is blown to the indoor environment, so that the indoor environment is refrigerated and heated.

The second column casing 70 is vertically cylindrical and is disposed side by side with the first column casing 10 in the lateral direction, that is, the second column casing 70 is disposed at the left side or the right side of the first column casing 10. An air outlet space 13 is formed between the first cylindrical shell 10 and the second cylindrical shell 70, and a second air outlet 82 is provided at the front side of the second cylindrical shell 70 for blowing out the non-heat exchange 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.

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 alternatively or simultaneously start air supply. When the at least one first air outlet 12 and/or the second air outlet 22 is/are air-out, the indoor air in the air inducing interval 13 is driven to flow forwards by virtue of the negative pressure.

The first air outlet 12 and the second air outlet 22 may be integrally formed in a vertical bar shape extending from top to bottom, or may be formed in an intermittent vertical bar shape consisting of a plurality of sub air outlets vertically arranged, so as to fully utilize the height space of the first column casing 10 and the second column casing 20.

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 present invention, when the first casing 10 and/or the second casing 20 is/are air-out, a negative pressure environment is formed at the air-inducing interval 13, so that indoor air behind the indoor unit of the vertical air conditioner is caused to flow forward through the air-inducing interval 13 to mix with the air-out air flow of the first casing 10 or the second 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.

In some embodiments of the present invention, the air conditioner indoor unit is further configured to have an operation mode in which the heat exchange air flow blown out from the first air outlet 12 and the non-heat exchange air flow blown out from the second air outlet 22 are mixed in front of the air conditioner indoor unit. Specifically, the normal directions of the first air outlets 11, 12 and the second air outlet 22 may be made to sandwich an angle greater than 0 so that the multiple air-out flows can be mixed. Of course, the wind guide structure is also used for guiding wind, so that a plurality of air outlet air flows can be mixed. In this way, when the second casing 20 also blows out the indoor air, the mixing amount and mixing speed of the indoor air are increased, a stronger air mixing effect can be achieved, and the airflow is brought closer to room temperature. 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.

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 products. For example, the ratio of the width of the second column casing 20 in the lateral direction to the width of the first column casing 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.

In some embodiments, an air guiding device is disposed at each first air outlet 11, 12 to change the included angle between the flow direction of the heat exchange air flow and the flow direction of the non-heat exchange air flow. As shown in fig. 2 and 3, the air guiding device is an air guiding duct 50. Each air duct 50 is rotatably provided at the first air outlet 11 or the first air outlet 12, and the peripheral wall of each air duct 50 includes at least two ventilation sections 52, 53 and one wind shielding section 51 arranged along the circumferential direction thereof. The air duct 50 has a hollow structure and a cavity inside. For example, as shown in fig. 2, the air duct 50 may be provided with only two ventilation sections 52, 53. Of course, more ventilation sections may be provided. The ventilation sections 52, 53 refer to sections through which air flows into and out of the duct 50, and the wind shielding section 51 refers to solid sections through which air flows cannot pass.

Each air duct 50 is configured to be rotatable to a position in which either ventilation section 52, 53 is opposed to the first air outlet 11, 12 to allow the air-out air to flow through that ventilation section 52, 53 into the air duct 50, then blow out through the other ventilation section and then blow out to the indoor environment, and to allow the air duct 50 to rotationally adjust the orientation of the ventilation section 52, 53 for the air-out to change the direction of the air-out. It should be noted that "any ventilation section" is not a specific one, and all or at least part (at least two) of the ventilation sections 52, 53 in this embodiment can be used opposite the first air outlets 11, 12, and that it is optional to specifically activate which ventilation section 52, 53 is opposite the first air outlet 11, 12. Alternatively, the air duct 50 may also be rotated to a position where the wind shielding section 51 is opposite to the first air outlets 11, 12, so as to shield the first air outlets 11, 12, as shown in fig. 2.

In this way, the air-out flows of the first air outlets 11, 12 are not directly blown to the indoor environment, but enter the air duct 50 through a certain ventilation section 52, 53, and are blown out through the other ventilation section 52, 53 of the air duct 50 after being gathered in the inner cavity of the air duct 50 for a short time. In this way, the ventilation sections 52 and 53 can be switched to be opposite to the first air outlets 11 and 12 by rotating the air duct 50, and the different ventilation sections 52 and 53 are used for supplying air indoors, so as to finally achieve the purpose of changing the air supply effect. For example, the direction and the air volume of the air supply can be made different by making the direction and the air outlet area of the different ventilation sections 52 and 53 at the air supply position different, and the structure is very novel and ingenious.

In some embodiments, as shown in fig. 2 and 3, each ventilation section 52, 53 is plate-shaped provided with a plurality of ventilation holes 502. Referring to fig. 3, when the indoor unit of the vertical air conditioner is operated, the heat exchange air flow enters the air duct 50 through one ventilation section 52 and is blown out through the other ventilation section 53. In this process, the air-out air flow passes through the ventilation section twice, is scattered twice, and turns around in the air duct 50, so that the softness is further enhanced, the air flow noise is lower, and the wind sense is softer. The indoor unit of the vertical air conditioner creates a silent and comfortable air supply environment, and the human body feels more comfortable.

Specifically, each air vent 502 may be a long hole with a length direction parallel to the length direction of the air duct 50, and the air vents 502 are sequentially arranged at intervals along the circumferential direction of the air duct 50. Compared with round holes or square holes which are arranged in a matrix, the strip holes have larger ventilation area so as to avoid unsmooth air outlet caused by too small ventilation area, thereby affecting the refrigerating/heating efficiency of the vertical air conditioner indoor unit. The two ends of each air-dispersing hole 502 in the length direction can be extended to the positions adjacent to the two ends of the air duct 50 in the length direction, so that the length of the air-dispersing hole can cover the whole length direction of the air outlet.

In some embodiments, the width of any one of the air-diffusing holes 502 may be made to be m, and the width of the solid portion spaced between the air-diffusing hole 502 and any adjacent air-diffusing hole 502 is made to be n, so that 2≤m/n≤4 is satisfied. Preferably, 2.5≤m/n≤3.5, e.g. m/n=3. Thus, the balance of the smoothness and the softness of the air outlet can be realized. The width m of each of the ventilation holes 502 may be the same or different. The widths n of the respective physical portions may be the same or different. Preferably, the width m of each of the ventilation holes 502 is the same, and the width n of each of the solid portions is the same.

In some embodiments, as shown in fig. 2, each first air outlet 11, 12 may be biased to open obliquely forward in a direction laterally away from the first column casing 10. That is, the left first air outlet 11 is opened to the left front, and the right first air outlet 12 is opened to the right front. Further, a movable first air deflector 60 is provided at each first air outlet 11, 12 for opening or shielding the lateral air outlet path of the first air outlet 11, 12. For example, for the first air outlet 11 on the left side, shielding the first air deflector 60 from the air outlet path of the first air outlet 11 means that the first air deflector 60 is blocked on the left side of the first air outlet 11 so that air cannot be discharged to the left side. The lateral air outlet path of the open air outlet 11 means that the first air deflector 60 is opened to the left side of the first air outlet 11 so that it can normally air-out to the left. Accordingly, the air conditioner can control whether the first air outlets 11, 12 transversely discharge air or not by controlling the first air deflector 60. The first air deflection 60 may be driven to translate back and forth using a motor and rack and pinion arrangement.

When the first air deflector 60 shields the lateral air outlet path of the first air outlets 11, 12, the air duct 50 may be rotated to a position where the air shielding section 51 shields other portions of the first air outlets 11, 12, so that the first air outlets 11, 12 are closed, as shown in fig. 2. That is, the embodiment of the present invention can jointly close the first air outlets 11, 12 by using the first air guiding plate 60 and the air guiding duct 50.

As shown in fig. 2 and 4, each first air deflector 60 may be mounted to the first column casing 10 in a front-to-rear translation manner so as to be retracted back into the interior of the first column casing 10 to open the lateral air outlet path of the first air outlets 11, 12, as shown in fig. 4, or extended forward out of the first column casing 10 to block the lateral air outlet path of the first air outlets 11, 12, as shown in fig. 2.

In some embodiments, each barrel 50 may be generally prismatic in shape with at least some of its sidewalls constituting ventilation sections 52, 53 and wind shielding section 51. The prism has a plurality of side walls and two end walls in the axial direction. For example, a triangular prism has three side walls and a triangular prism has four side walls. At least some of the plurality of side walls constitute ventilation sections 52, 53. As shown in fig. 1 to 4, the air duct 50 may be formed in a triangular prism shape as a whole, and two of three side walls thereof (i.e., three side surfaces of the triangular prism) constitute two ventilation sections 52, 53, and the other constitutes a wind shielding section 51. In some alternative embodiments, the air duct 50 may be a quadrangular prism, a pentagonal prism, or the like, so as to design more ventilation sections. Alternatively, the air duct 50 may have a cylindrical shape, an elliptic cylindrical shape, or the like, and of course, the air duct 50 may have other irregular shapes.

In some embodiments, the air duct 50 is formed as a regular triangular prism shape as a whole, that is, the included angle between any two adjacent side walls is 60 °, and the rotation axes x1 and x2 of the air duct 50 are parallel to the central axis of the triangular prism, so that when the air duct 50 rotates around its axis, each side wall can rotate to a position for closing the first air outlet 11 and 12.

It is to be understood that embodiments of the present invention do not require that barrel 50 be a right geometry triangular prism. In the actual design and manufacturing process, the edges of the steel plates can be provided with fillets, and the side surfaces of the steel plates can be designed to be non-planar, such as cambered surfaces and the like. Of course, the air duct 50 may have a quadrangular prism shape or a penta prism shape. The air duct 50 may be cylindrical or elliptical. Such modifications are readily apparent to those skilled in the art and are not described in great detail herein.

Fig. 5 is a schematic view of the indoor unit of the vertical air conditioner shown in fig. 2 when the indoor unit of the vertical air conditioner is switched to the surrounding breeze mode, fig. 6 is a schematic view of the indoor unit of the vertical air conditioner shown in fig. 2 when the indoor unit of the vertical air conditioner is switched to the front air supply mode, fig. 7 is a schematic view of the indoor unit of the vertical air conditioner shown in fig. 2 when the indoor unit of the vertical air conditioner is switched to the left air supply mode, and fig. 8 is a schematic view of the indoor unit of the vertical air conditioner shown in fig. 2 when the indoor unit of the vertical air conditioner is switched to the right air supply mode.

In the embodiment of the invention, by arranging the two first air outlets 11 and 12 and the two air guide cylinders 50, multiple air supply modes are obtained.

When the indoor unit of the vertical air conditioner is in the off state, as shown in fig. 2, the two first air deflectors 60 and the second air deflectors 90 are both in the off state, and the wind shielding sections 51 of the two air ducts 50 respectively shield the front parts of the first air outlets 11 and 12, so that the first air outlets 11 and 12 and the second air outlet 82 are both closed.

As shown in fig. 3, the vertical air conditioner indoor unit is configured to allow the air outlet direction of the ventilation section 53 for air outlet of the two air ducts 50 to sandwich an acute angle so as to aggregate the two heat exchange airflows blown out from the two first air outlets 11, 12 in front of the first column casing 10, as shown in fig. 3. That is, the air outlet directions of the two first air outlets 11 and 12 are gradually approaching each other in the forward flowing process, so that two air flows are converged into one air flow, the wind power is very strong, the air supply distance is longer, and the requirements of the air conditioner indoor unit on long-distance air supply and strong air supply are met. The indoor unit of the floor air conditioner may be provided with a human body sensor, and when the human body sensor detects that a person is far from the indoor unit of the floor air conditioner, the two air ducts 50 may be rotated to operate the aggregate air supply mode. At this time, the second air deflector 90 may be configured to guide the air-out flow of the second air outlet 82 in a direction approaching the first column casing 10 so as to be converged into the heat exchange air flow.

As shown in fig. 4, the two first air deflectors 60 may be opened, and the two air ducts 50 may be rotated to make the ventilation section 52 for air outlet face the lateral direction, so that the first air outlet 11 on the left side faces the left air outlet, and the first air outlet 12 on the right side faces the right air outlet, so as to form an encircling air supply mode. At this time, the second air deflector 90 may be configured to guide the air-out flow of the second air outlet 82 in a direction away from the first column casing 10 so as to be converged into the heat exchange air flow.

As shown in fig. 5, compared with fig. 4, the two wind shielding sections 51 are directed forward so that the ventilation section 52 for air outlet is directed obliquely rearward, and after the heat exchange air flow is blown out, the human body feel weaker, and a gentle surrounding wind mode is formed.

As shown in fig. 6, the two ventilation sections 53 for air-out are directed forward so as to air-out toward the front, forming a front air-blowing mode. As shown in fig. 7, two ventilation sections 53 for air-out are directed to the left front so as to air-out to the left front, forming a left air-blowing mode. As shown in fig. 8, two ventilation sections 53 for air-out are directed to the right front so as to air-out to the right front, forming a right air-blowing mode.

It should be noted that the foregoing merely illustrates some of the alternative modes of air delivery of the present invention, and that some modes of air delivery are not explicitly listed.

In some embodiments, the body position and body condition may be detected using sensors, and the controller adjusts the air delivery mode accordingly.

For example, when it is detected that a human body is approaching the floor air conditioner indoor unit from far to near, the front air supply mode may be operated. When the human body is detected to be positioned right in front of the indoor unit of the vertical air conditioner, the surrounding type air supply mode can be operated. The air flow surrounds the air outlet from two sides, at the moment, the left side only has the hot air exchange, and the right side is the mixed air of the hot air exchange and the indoor drainage air, so that the air flow efficiency of the space is improved, and the comfort of personnel is improved.

When the human body is detected to be positioned at the left/right front of the indoor unit of the vertical air conditioner, the air conditioner enters a left air supply mode/a right air supply mode, and air flow is supplied to the left/right front. When the human body is detected to be in a sleeping or quiet state, the device enters a surrounding breeze mode, at the moment, the wind speed is low, the noise is low, the wind sense is soft, the air flow is slowly sent out from two sides, and a quiet and comfortable environment is created for a user.

In some embodiments, as shown in fig. 1 and 2, the floor air conditioner indoor unit further includes a lower column casing 100. The lower column casing 100 constitutes a lower structure of the indoor unit of the floor air conditioner, in which some other components of the air conditioner, such as a purifying component, etc., may be disposed. When the floor type indoor unit of the floor type air conditioner is used, the bottom of the lower column casing 100 is placed on the ground. The bottoms of the first and second column casings 10 and 70 are connected to the top of the lower column casing 100. The first column housing 10 and/or the second column housing 70 may be formed as an integral structure with the lower column housing 100. In some embodiments.

In some embodiments, as shown in fig. 2 and 3, the peripheral wall of the second casing 70 may be provided with a second air inlet 81 opened toward the indoor environment for introducing indoor air. The floor air conditioner indoor unit further includes a second fan 42 disposed within the second casing 70 for blowing the non-heat exchanging air flow out through the second air outlet 22. The second fan 42 may be a through-flow fan, so that a second air duct 80 is formed in the second casing 70, the second air duct 80 is a through-flow air duct, and an inlet and an outlet of the second air duct 80 are respectively connected with the second air inlet 81 and the second air outlet 82. By arranging the special through-flow air duct, the air flow resistance can be smaller.

In addition, as shown in fig. 2 and 3, a second air deflector 90 may be disposed at the second air outlet 82, and the second air deflector 90 may be rotatably mounted on the second casing 70 about a vertical axis, so as to be used for opening and closing the second air outlet 82 and guiding the air outlet direction of the second air outlet 82.

In some alternative embodiments, the air inlet of the second column housing 70 may also be in communication with the lower column housing 100 to introduce one or more of various conditioned air streams, such as indoor air, purified air streams, humidified air streams, fresh air streams, and the like, from the lower column housing 100. Alternatively, the second housing 70 may itself be provided with a fresh air module, a purifying module, or a humidifying module, so as to produce a purified air flow, a humidified air flow, a fresh air flow, or the like.

In some embodiments, as shown in fig. 2 and 3, the indoor unit of the vertical air conditioner further includes at least one first fan 41, and the number of the first fans 41 may be one or more. As shown in fig. 2, the number of first fans 41 may be made one. A first fan 41 is provided within the first cylindrical shell 10 for delivering a flow of heat exchanged air to the first air outlets 11, 12. Further, the ratio of the rated air volume of the second fan 42 to the rated air volume of the first fan 41 may be made to be between 0.35 and 0.45, inclusive, preferably between 0.39 and 0.41, for example 0.4. The second fan 42 is designed to be smaller in this embodiment so as to have smaller power, and also to avoid discomfort caused by too severe indoor air flow due to too large wind power.

In some embodiments, as shown in fig. 4, the ratio of the width B2 of the second column casing 70 in the transverse direction to the width B1 of the first column casing 10 in the transverse direction is between 0.2 and 0.25, inclusive, preferably between 0.22 and 0.24. The asymmetric design meets the air mixing requirement on one hand, and enables the appearance of the indoor unit of the vertical air conditioner to be novel and unique on the other hand, and the competitiveness of products is improved.

In some embodiments, as shown in fig. 4, the two lateral sides 18 of the first column casing 10 may be vertical surfaces extending front and back, the back 19 is a convex curved surface, and two sides are tangent to the two lateral sides 18. Similarly, the two lateral sides 78 of the second casing 70 are vertical surfaces extending forward and backward, and the back 79 is a convex curved surface and two sides are tangent to the two lateral sides 78. The round shape can enable indoor air to enter the air outlet space 13 more smoothly, and the air mixing effect is enhanced.

As shown in fig. 2, a first air duct 20 may be further disposed in the first column casing 10, and an open front side of the first air duct 20 is opened to communicate with the two first air outlets 11, 12. The number of first fans 41 is also one, which is provided at the inlet of the first air duct 20. The first fan 41 may be a cross-flow fan, and the first air duct 20 is a cross-flow air duct accordingly. The first column casing 10 includes a partition 15 between the first air outlet 11 and the first air outlet 12 to guide the air-out flow of the first air duct 20 to the two first air outlets 11, 12. The partition 15 may have a columnar structure with a rear surface having a rear convexly curved surface and a front surface having a flat surface.

A heat exchanger 30 may be disposed within the first column housing 10. The first column casing 10 may be provided with an air inlet, and the heat exchanger 30 and the throttling device are connected with a compressor, a condenser and other refrigerating elements arranged in the outdoor unit of the air conditioner through pipelines to form a vapor compression refrigeration cycle system. Under the action of the first fan, indoor air enters the first column casing 10 through the air inlet, forms heat exchange airflow after forced convection heat exchange with the heat exchanger 30, enters the first air duct 20, and is blown into a room through the first air outlets 11 and 12 of the first column casing 10.
