The invention provides a vertical air conditioner indoor unit.

The vertical air conditioner indoor machine can be a conventional floor type cabinet machine or a vertical wall-mounted machine.

Fig. 3 shows the flow direction of the heat exchange air flow by solid arrows, and the flow direction of the indoor air by hollow arrows.
As shown in fig. 1 to 4, a vertical air conditioning indoor unit embodying the present invention may generally include a first cylindrical casing 10 and a second cylindrical casing 70.
The first column shell 10 is in a vertical column shape, and two first air outlets 11 and 12 which are arranged side by side in the transverse direction are arranged on the front side of the first column shell and used for blowing out heat exchange air flow. The "lateral direction" is indicated in the drawing, 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 vertical air conditioner indoor unit is in a refrigeration mode, the heat exchange air flow is cold air. When the vertical air conditioner indoor unit is in a heating mode, the heat exchange air flow is hot air. The heat transfer gas flows through the first air outlets 11 and 12 and is blown to the indoor environment, so that the indoor environment is cooled and heated.
The second cylindrical shell 70 is in a vertical column shape, and is disposed side by side with the first cylindrical shell 10 in a transverse direction, that is, the second cylindrical shell 70 is disposed on the left side or the right side of the first cylindrical shell 10. An air outlet interval 13 is formed between the first cylindrical shell 10 and the second cylindrical shell 70, and a second air outlet 82 is arranged at the front side of the second cylindrical shell 70 and used for blowing out non-heat-exchange air flow. Specifically, the non-heat exchange air flow may be one or more of indoor air, fresh air flow, purified air flow, humidified air flow or water washing air flow, and is used for auxiliary regulation of indoor environment.
When the vertical air conditioner indoor unit of the embodiment of the invention operates, the first cylindrical shell 10 and the second cylindrical shell 20 are alternatively or simultaneously started to supply air. When the air is discharged from at least one first air outlet 12 and/or second air outlet 22, the indoor air in the air inducing interval 13 is driven to flow forwards under the action of negative pressure.
The first outlet 12 and the second outlet 22 may be a vertical bar extending from top to bottom, or may be an intermittent vertical bar formed by a plurality of vertically arranged sub-outlets, so as to fully utilize the height space of the first cylindrical shell 10 and the second cylindrical shell 20.
The existing vertical air conditioner indoor unit has the defects of unobvious appearance difference and poor air supply experience, so that a user has many complaints. Particularly, when an air conditioner is used for refrigeration, the air outlet temperature is often low, the air speed is high, and cold air directly blows to a human body to cause discomfort, that is, the wind is hard and not soft enough.
In the embodiment of the invention, when the first cylindrical shell 10 and/or the second cylindrical shell 20 is/are exhausted, a negative pressure environment is formed at the induced air interval 13, so that indoor air at the rear of the vertical air conditioner indoor unit is promoted to flow forwards through the induced air interval 13 to be mixed with the exhausted air flow of the first cylindrical shell 10 or the second cylindrical shell 20, and a flow-guiding and air-mixing effect is formed. Compared with heat exchange airflow, the temperature of the mixed air flow is closer to 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 invention, the indoor unit of a floor air conditioner is further configured to: the operation mode is that 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 indoor unit of the vertical air conditioner. Specifically, the normal directions of the first outlet 11, 12 and the second outlet 22 may be held at an angle greater than 0, so that the multiple outlet flows can be mixed. Of course, also carry out the wind-guiding through wind-guiding structure, make stranded air-out air current can mix. Thus, when the indoor air is blown out from the second cylindrical shell 20, the mixing amount of the indoor air is larger, the mixing speed is higher, a stronger air mixing effect can be realized, and the airflow is closer to the room temperature. When the second cylindrical shell 20 blows out conditioning air flows such as fresh air flow, purified air flow, humidifying air flow or washing air flow, the conditioning air flows can be mixed with the heat exchange air flow more early and more, the mixing rate is enhanced, and the conditioning air flows can be better diffused to all places indoors.
In addition, because need not to set up the heat exchanger in the second shell 20, can be thinner with the design of second shell 20 ground, make it obviously be thinner than first shell 10, this kind of asymmetric design both had satisfied the needs of mixing the wind just, made the outward appearance of vertical air conditioning indoor set novel more unique again, had promoted the competitiveness of product. 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 a distance between two points at which the outer walls of the second cylindrical shell 20 or the first cylindrical shell 10 are farthest in the lateral direction. The ratio of the depth of the second column shell 20 in the front-rear direction to the depth of the first column shell 10 in the front-rear direction is less than 1/2, which means the distance between two points where the front and rear outer walls of the second column shell 20 or the first column shell 10 are most distant in the front-rear direction. Thus, the size difference between the two is large enough, and the appearance of double-column differentiation is formed. The second outlet 22 can be flush or substantially flush with the front and back of the first outlet 12, for example, the distance between the front and back is not more than 5cm, so that the non-heat exchange air flow and the heat exchange air flow are mixed better.
In some embodiments, an air guiding device is disposed at each of the first air outlets 11 and 12 to change an included angle between the flow directions of the heat exchange air flow and the non-heat exchange air flow. As shown in fig. 2 and 3, the air guide device is an air guide duct 50. Each air duct 50 is rotatably disposed at the first outlet 11 or the first outlet 12, and a peripheral wall of each air duct 50 includes at least two ventilation sections 52, 53 arranged along a circumferential direction thereof and one wind shielding section 51. The air duct 50 has a hollow structure and has a hollow cavity therein. For example, as shown in fig. 2, it is possible to provide the air guide duct 50 with only two ventilation sections 52, 53. Of course, more ventilation sections may be provided. The ventilation sections 52 and 53 refer to sections through which air can enter and exit the air guide duct 50, and the wind shielding section 51 refers to a solid section through which air cannot pass.
Each air guide duct 50 is configured to: the air duct can be rotated to a position where any one of the ventilation sections 52, 53 is opposite to the first air outlets 11, 12, so as to allow the air to flow through the ventilation sections 52, 53 and enter the air duct 50, then blow out through the other ventilation sections, and blow towards the indoor environment, and further, the air duct 50 is allowed to rotatably adjust the orientation of the ventilation sections 52, 53 for air outlet, so as to change the air outlet direction. 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 can be used opposite to the first air outlets 11, 12 in this embodiment, and it is optional to specifically activate which ventilation section 52, 53 is opposite to the first air outlet 11, 12. Alternatively, the air duct 50 can also rotate to a position where the wind shielding section 51 is opposite to the first outlets 11 and 12, so as to shield the first outlets 11 and 12, as shown in fig. 2.
Thus, the air flow from the first outlet 11, 12 does not directly blow to the indoor environment, but enters the air duct 50 through a certain ventilation section 52, 53, is temporarily collected in the inner cavity of the air duct 50, and then blows out through the other ventilation section 52, 53 of the air duct 50. Thus, different ventilation sections 52, 53 can be switched to be opposite to the first air outlets 11, 12 by rotating the air duct 50, and the different ventilation sections 52, 53 are used for supplying air to the indoor space, thereby finally achieving the purpose of changing the air supply effect. For example, the parameters such as the direction and the air outlet area of the different ventilation sections 52 and 53 at the air supply position can be different, so that the wind direction and the air volume are different when the air is supplied, 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 air dispersion holes 502. Referring to fig. 3, when the indoor unit of the air conditioner is operated, the heat exchange air flow enters the inside of the air guide duct 50 through one ventilation section 52 and is then blown out through the other ventilation section 53. In the process, the air outlet flow passes through the ventilation section twice and is broken up twice, and the air duct 50 is circularly arranged inside, so that the softness of the air duct is further enhanced, the noise of the air flow is lower, and the wind sensation is softer. The vertical air conditioner indoor unit creates a quiet and comfortable air supply environment, so that a human body feels more comfortable.
Specifically, each of the air diffusing holes 502 may be a long hole having a length direction parallel to the length direction of the air guiding duct 50, and the air diffusing holes 502 may be sequentially arranged at intervals in the circumferential direction of the air guiding duct 50. Compared with round holes or square holes arranged in a matrix manner, the ventilation area of the strip holes is larger, so that unsmooth air outlet caused by too small ventilation area is avoided, and the refrigerating/heating efficiency of the vertical air conditioner indoor unit is influenced. 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 air dispersing hole 502 can be m, and the width of the solid part spaced between the air dispersing hole 502 and any adjacent air dispersing hole 502 can be n; satisfies the following conditions: m/n is more than or equal to 2 and less than or equal to 4. Preferably, 2.5. Ltoreq. M/n.ltoreq.3.5, for example m/n =3. Therefore, the balance between smoothness and softness of air outlet can be realized. The width m of each air dispersing hole 502 may be the same or different. The width n of each solid portion may be the same or different. Preferably, the width m of each air dispersing hole 502 is the same, and the width n of each solid portion is the same.
In some embodiments, as shown in fig. 2, each of the first air outlets 11, 12 may be inclined in a direction laterally away from the first cylindrical shell 10 to open obliquely forward. That is, the left first outlet 11 is opened to the front left, and the right first outlet 12 is opened to the front right. In addition, a movable first air deflector 60 is disposed at each of the first outlets 11 and 12, so as to open or block the transverse air outlet path of the first outlets 11 and 12. For example, for the left first outlet 11, blocking the air outlet path of the first outlet 11 by the first air deflector 60 means blocking the left side of the first outlet 11 by the first air deflector 60, so that air cannot be discharged to the left side. The opening of the transverse air outlet path of the air outlet 11 means that the first air deflector 60 opens the left side of the first air outlet 11, so that air can be normally discharged to the left. Accordingly, the air conditioner can control whether the first outlets 11 and 12 are transversely discharged air by controlling the first air deflector 60. The first air guiding plate 60 can be driven to move back and forth by a motor and a gear rack structure.
When the first air guiding plate 60 blocks the transverse air outlet paths of the first outlets 11 and 12, the air duct 50 may rotate to a position where the wind shielding section 51 blocks other portions of the first outlets 11 and 12, so that the first outlets 11 and 12 are closed, as shown in fig. 2. That is, the first air guiding plate 60 and the air duct 50 can be used to close the first air outlets 11 and 12.
As shown in fig. 2 and 4, each first air deflector 60 may be mounted to the first cylindrical shell 10 in a front-back translational manner so as to be retracted into the first cylindrical shell 10 to open the transverse air outlet path of the first air outlet 11, 12, as shown in fig. 4; or extend the first cylindrical shell 10 forward to block the transverse air outlet path of the first air outlet 11, 12, as shown in fig. 2.
In some embodiments, each air duct 50 may be formed in a prism shape as a whole, and at least some of the plurality of side walls thereof constitute the ventilation sections 52, 53 and the wind shielding section 51. The prism has a plurality of side walls and two axial end walls. For example, a triangular prism has three sidewalls and a quadrangular prism has four sidewalls. At least some of the plurality of side walls constitute the ventilation sections 52, 53. As shown in fig. 1 to 4, the air guide duct 50 may be formed in a triangular prism shape as a whole, two of three side walls (i.e., three side surfaces of the triangular prism) of which constitute two ventilation sections 52 and 53, and the other of which constitutes a wind shielding section 51. In some alternative embodiments, the wind guiding barrel 50 may also be a polygonal prism such as a quadrangular prism, a pentagonal prism, etc. in order to design more ventilation sections. Alternatively, the air guide duct 50 may have a cylindrical shape, an elliptic cylindrical shape, or the like, but the air guide duct 50 may have another irregular shape.
In some embodiments, the air duct 50 is shaped like a regular triangle prism as a whole, that is, the included angle between any two adjacent side walls is 60 °, and the rotation axes x1 and x2 thereof are parallel to the central axis of the triangle prism, so that when the air duct 50 rotates around the axis, each side wall thereof can rotate to the position of closing the first air outlet 11 and 12.
It will be appreciated that embodiments of the invention do not require the wind scoops 50 to be strictly geometrically triangular prisms. In the actual design and manufacturing process, the edges can also be provided with round corners, and the side surfaces can also be designed to be non-planar surfaces, such as cambered surfaces and the like. Of course, the air duct 50 may have a quadrangular prism shape or a pentagonal prism shape. The air duct 50 may have a cylindrical shape or an elliptic cylindrical shape. Such modifications are readily understood and made by those skilled in the art, and are not described herein in any greater extent.

In the embodiment of the present invention, by providing the two first air outlets 11 and 12 and the two air ducts 50, a plurality of air supply modes are obtained.
When the indoor unit of the floor air conditioner is in a shutdown state, as shown in fig. 2, the two first air deflectors 60 and the second air deflector 90 are both in a closed state, and the wind shielding sections 51 of the two air ducts 50 shield the front portions of the first wind outlets 11 and 12, respectively, so that the first wind outlets 11 and 12 and the second wind outlet 82 are both closed.
As shown in fig. 3, the indoor unit of a floor standing air conditioner is configured to allow the air outlet directions of the ventilating sections 53 for air outlet of the two air ducts 50 to have an acute angle therebetween, so that the two heat exchange air flows blown out from the two first air outlets 11 and 12 converge in front of the first cylindrical casing 10, as shown in fig. 3. That is to say, the air outlet directions of the two first air outlets 11 and 12 are gradually close to 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 farther, and the requirements of the indoor unit of the air conditioner on long-distance air supply and strong air supply are met. The indoor unit of the vertical air conditioner can be provided with a human body sensor, and when the human body sensor detects that a person is far away from the indoor unit of the vertical air conditioner, the two air ducts 50 can be rotated to operate a polymerization air supply mode. At this time, the second air guiding plate 90 can guide the outlet airflow of the second air outlet 82 toward the direction close to the first cylindrical shell 10, so as to converge the heat exchange airflow.
As shown in fig. 4, the two first air guiding plates 60 can be in an open state, and the two air guiding cylinders 50 are rotated to make the ventilating section 52 for air outlet face the transverse 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 guiding plate 90 can guide the outlet airflow of the second air outlet 82 to a direction away from the first cylindrical shell 10, so as to converge the heat exchange airflow.
As shown in fig. 5, compared with fig. 4, the two wind shielding sections 51 are directed forward, and the ventilation section 52 for blowing the wind is directed obliquely rearward, so that after the heat exchange airflow is blown out, the wind sensation of the human body is weaker, and the surrounding breeze mode is formed.
As shown in fig. 6, the two ventilation sections 53 for air outlet are directed forward to discharge air forward, so as to form a forward blowing mode. As shown in fig. 7, two ventilation sections 53 for blowing air are directed to the front left to blow air to the front left, thereby forming a left air blowing mode. As shown in fig. 8, two ventilation sections 53 for blowing air are directed to the front right to blow air to the front right, thereby forming a right blowing mode.
It should be noted that the above only illustrates some of the alternative blowing modes of the present invention, and some blowing modes are not explicitly listed.
In some embodiments, sensors may be used to detect body position and body condition, and the controller adjusts the air supply pattern accordingly.
For example, when a human body is detected to approach the indoor unit of the vertical air conditioner from far to near, the front air supply mode can be operated. When detecting that the human body is positioned right ahead of the indoor unit of the vertical air conditioner, the surrounding type air supply mode can be operated. The air current encircles the air-out from both sides, and the left side only has the mixed wind of trading hot-blast and indoor drainage wind for trading hot-blast this moment, and the right side is favorable to strengthening space air flow efficiency, promotes personnel's travelling comfort.
When the human body is detected to be positioned at the left/right front of the indoor unit of the vertical air conditioner, the left air supply mode/the right air supply mode is entered, and at the moment, the air flow supplies air to the left/right front. When the human body is detected to be in a sleeping or quiet state, the surrounding breeze mode is entered, at the moment, the wind speed is low, the noise is low, the wind sense is soft, the airflow is slowly sent out from two sides, and a quiet and comfortable environment is created for users.
