As shown in fig. 1 to 5, the indoor unit of a floor air conditioner according to an embodiment of the present invention may generally include a cabinet 10 and at least one guide 50.

The casing 10 extends in a vertical column shape, that is, the casing 10 is a long strip extending in the up-down direction. At least one air duct 20 is defined in the casing 10, and the casing 10 is provided with at least one vertical bar-shaped first air supply outlet 11 and at least one extended air supply part 141 (refer to the part marked by an ellipse in fig. 3). The casing 10 of the present embodiment includes a framework for forming a basic frame of the indoor unit, and body components such as a volute and a volute tongue for defining the air duct 20. The first air blowing port 11 is used for blowing an air flow in the casing 10 into the room to condition the indoor air. The air flow can be cold air produced by the indoor unit of the vertical air conditioner in a refrigeration mode, hot air produced in a heating mode, or fresh air introduced in a fresh air mode, and the like. The number of the air ducts 20 may be one or more.

The casing 10 is provided with an air inlet 13, and the air inlet 13 may be disposed on a rear surface of the casing 10 for introducing indoor air flow. In some embodiments, the indoor unit of the stand type air conditioner may be an indoor unit of an air conditioner that performs cooling/heating using a vapor compression refrigeration cycle system, in which the heat exchanger 40 is disposed. Indoor air enters the casing 10 through the air inlet 13, after heat exchange with the heat exchanger 40 is completed, enters the air duct 20 under the action of the fan, and is blown to the indoor environment through the first air supply outlet 11 to adjust the indoor environment air.

Each flow guiding member 50 is a column extending vertically, and each flow guiding member 50 is disposed at one first air supply opening 11, so as to define an air outlet gap 201 with an inner wall of the air duct 20 near the first air supply opening 11, so that the air flow at the first air supply opening 11 is blown to the indoor environment through the air outlet gap 201. Specifically, both sides of each air deflector 50 and both side inner walls of the air duct 20 may define an air outlet gap 201, as shown in fig. 3. Alternatively, only one side of each flow guide 50 and one side of the inner wall of the air duct 20 may define an air outlet gap 201, and the other side of each flow guide is tightly attached to the inner wall of the air duct 20, so that no air outlet gap is formed and air cannot be exhausted. The air current blows out through the air-out clearance 201 between the inner wall of wind channel 20 and water conservancy diversion spare 50, makes the air current directly blow the human body at big amount of wind, makes human feel more comfortable. The smaller the outlet air gap 201 is designed, the finer the outlet air flow is, and the smaller the wind sensation is.

Further, each of the air deflectors 50 can be made to change position (including translation, rotation or compound movement) to adjust the size of the air outlet gap 201 to change the flow area (including adjusting the flow area to 0, as shown in fig. 4, so that the air deflectors 50 close the first air supply opening 11) to adjust the wind power of the first air supply opening 11. Specifically, the wind power can be increased by enlarging the wind outlet gap 201 to more rapidly cool/heat; wind power is reduced by reducing the air outlet gap 201, natural wind is simulated, and the air flow comfort degree is higher.

The vertical air conditioner indoor unit is configured as follows: the air duct 20 is communicated with the first air supply outlet 11, as shown in fig. 3; or the first blowing port 11 and the extended blowing part 141 are communicated with each other, as shown in fig. 4. That is, the outlet direction of the air duct 20 is optional, and the air conditioner can selectively activate or deactivate the extended air supply part 141, so as to change the outlet effect and make the air supply adjusting mode of the indoor unit of the floor air conditioner more diversified. As shown in fig. 3, the air duct 20 is communicated with the first air supply outlet 11, and air is discharged from the first air supply outlet 11; as shown in fig. 4, the first air blowing port 11 and the extended air blowing unit 141 are communicated with each other through the air duct 20, and the first air blowing port 11 is closed by the baffle 50 and air is blown by the extended air blowing unit 141; alternatively, as shown in fig. 5, the air duct 20 communicates the first air blowing port 11 and the extended air blowing unit 141, and the first air blowing port 11 is opened to blow air simultaneously from the first air blowing port 11 and the extended air blowing unit 141.

The extended blowing part 141 may be composed of a plurality of air dispersing minute holes 141 a. The air outlet quantity of the air dispersing micropores 141a is very small, so that the air outlet flow is very fine, and the human body feels very comfortable. For example, as shown in fig. 1, each of the air dispersing micro holes 141a is a vertical bar hole, and the air dispersing micro holes 141a are arranged in the transverse direction. Of course, each air dispersing micropore can also be a round hole, a square hole, an elliptical hole or a hole with other shapes. The extended blowing part 141 may have a structure such as an outlet grill or a blowing hole.

In some embodiments, the enclosure 10 includes a first air duct wall and a second air duct wall that define the air duct 20. The outlet end of the first air duct wall constitutes one end of the first air blowing port 11 remote from the extended air blowing part 141. The second air duct wall comprises a second body section 22 and an adjustment section 25 (the axis of rotation being the x-axis) rotatably mounted to the second body section 22. In this way, the outlet direction of the air duct 20 can be changed by rotating the adjusting section 25. Specifically, when the adjusting section 25 is rotated to have its end between the first blowing port 11 and the extended blowing portion 141, the duct 20 is made to communicate with the first blowing port 11, as shown in fig. 3. When the adjusting section 25 is rotated to have its end adjacent to the end of the extended blowing part 141 remote from the first blowing port 11, the duct 20 is made to communicate the first blowing port 11 and the extended blowing part 141, as shown in fig. 4 and 5. Of course, a motor may be provided to drive the adjustment segment 25 to rotate. The motor is controlled by a main control panel of the vertical air conditioner indoor unit. In some embodiments, as shown in fig. 3 to 5, the first air duct wall comprises a first main section 21 and an end section 23 arranged at a distance from each other, the distance between the first main section 21 and the end section 23 constituting the second supply opening 12. The second supply port 12 functions as the first supply port 11, and is used to discharge airflow (heat exchange airflow, fresh air airflow, or the like) in the air duct 20 into the room. At least one air deflector 60 is disposed at the second air supply outlet 12 for opening and closing the second air supply outlet 12 and/or guiding the air outlet direction thereof. For example, as shown in fig. 1 to 4, a wind deflector 60 may be provided at each second air blowing opening 12, and a rear edge of the wind deflector 60 may be pivotally mounted to a rear edge of the second air blowing opening 12. In this way, it is convenient to guide the blowing air flow toward the front left or right, as shown in fig. 4. Of course, a plurality of air deflectors 60 may be provided in parallel for each second blowing port 12 to guide the wind direction by interlocking rotation. In addition, an air outlet structure such as an air outlet grille and a microporous plate can be arranged at the second air outlet 12. In some embodiments, as shown in fig. 1 to 5, the number of the air ducts 20 may be two, and the two air ducts 20 are arranged side by side along the transverse direction (i.e., the left-right direction) of the cabinet 10. The first blowing port 11 and the extended blowing part 141 of each duct 20 are opened forward and arranged side by side in the lateral direction of the cabinet 10, and the extended blowing part 141 is closer to the lateral center of the cabinet 10 than the first blowing port 11. Specifically, as for the left air duct 20, the extended air supply part 141 thereof is located on the right side of the first air supply outlet 11; the extended blowing portion 141 of the right air duct 20 is located on the left side of the first blowing port 11.

The first blowing ports 11 and the extended blowing portions 141 of the two air ducts 20 are opened forward, and the second blowing ports 12 of the two air ducts 20 are opened toward both lateral sides, respectively. In other words, the second supply port 12 of the air duct 20 on the left side is opened to the left, and the second supply port 12 of the air duct 20 on the right side is opened to the right. The number of the second air supply outlet 12 can be one or more, and the second air supply outlet 12 can also be vertical bar-shaped. The second air supply outlet 12 is not provided with the flow guide member 50, so that air can be smoothly discharged.

In this way, the indoor unit of the vertical air conditioner can perform small air volume air supply through the first air supply opening 11 and the plurality of air dispersion micropores 141a, and perform large air volume air supply through the second air supply opening 12, and various air supply modes can be obtained by matching the three. In the embodiment shown in fig. 1 to 3, each air duct 20 is provided with only one first air supply outlet 11 and one second air supply outlet 12, and each of the first air supply outlet 11 and the second air supply outlet 12 is in the shape of a vertical bar. Of course, it is also possible to provide a plurality of first air blowing ports 11 or a plurality of second air blowing ports 12 for each air duct 20, and arrange the plurality of first air blowing ports 11 or the plurality of second air blowing ports 12 in the vertical direction.

Thus, the two second air supply outlets 12 supply air to the left and right sides of the casing 10 with large air volume, so that the cooling/heating speed is faster and the human body is not directly blown. The air is blown forward by the two first blowing ports 11 and the plurality of air dispersing minute holes 141 a. In a word, the two air supply openings are matched, so that the air supply angle is larger.

In some embodiments, referring to fig. 3 and 4, the cabinet 10 includes a front center panel 14 constituting a front appearance thereof. The two transverse end sections of the front central panel 14 are respectively shielded at the outlets of the two air ducts 20, and are provided with a plurality of air-dispersing micro holes 141a to form two extended air-supplying portions 141. Two air outlet gaps 201 are formed between two lateral ends of the front central panel 14 and the two air deflectors 50. Specifically, the lateral ends of the front center panel 14 may have a rearward cuff 142 so that the air exit gap 201 acts a longer distance on the air flow. In other words, the duct 20 has a forward opening, and the portion shielded by the front center panel 14 constitutes the extension blowing part 141, and the portion not shielded by the front center panel 14 constitutes the first blowing port 11. Of course, both lateral ends of the front center panel 14 also belong to the housing portions defining the air chute 20.

In this embodiment, the front central panel is used to form the air-dispersing micropores 141a, so that the casing structure of the indoor unit of the vertical air conditioner is simpler, and the appearance is more complete and beautiful.

Fig. 6 is a schematic view of the floor type air conditioning indoor unit shown in fig. 3 in a state where both the first air outlet 11 and the second air outlet 12 are closed.

The vertical air conditioner indoor unit of the embodiment selects different air supply modes according to different working conditions. For example, in the cooling mode of the indoor unit of the vertical air conditioner, the air can be discharged from the first air outlet 11, and the air is not supplied from the second air outlet 12 and the air diffusion micropores 141a, so that cool and cold-free air supply experience is realized, and discomfort of a human body due to large amount of cold air flowing out is avoided, as shown in fig. 3; alternatively, the first air blowing port 11 and the plurality of air diffusing minute holes 141a are used to blow air, and the second air blowing port 12 is closed, thereby achieving a breeze effect with a larger air volume, as shown in fig. 5. In the heating mode, the first air supply outlet 11 can not supply air or supply a small amount of air, the air is discharged from the air dispersing micropores 141a (but the air volume is smaller), the air is mainly supplied by the second air supply outlets 12 on two sides, the air flows on two sides are respectively blown to the left side and the right side of the vertical air conditioner indoor unit, and the air flows are turned forwards after meeting a wall body, so that an air supply effect of surrounding by 180 degrees is formed, and a user feels stronger heating, and is more comfortable, as shown in fig. 4. When the indoor unit of the floor air conditioner is in the shutdown state, the first air supply outlet 11 and the second air supply outlet 12 are both in the closed state, and the adjusting section 25 is rotated to the state of not communicating with the air dispersing micropores 141a, so that various air supply channels of the casing 10 are all closed, as shown in fig. 6. Of course, it should be understood that the above air supply modes selected for the two working conditions are only some preferred solutions, the second air supply outlet 12 may be selected for supplying air during cooling of the air conditioner, and the first air supply outlet 11 may be selected for supplying air during heating of the air conditioner, and the present invention does not limit any combination manner of the air conditioner working conditions and the air supply modes. In the embodiment of fig. 3 to 5, the air blowing modes of the left and right air ducts are the same, but the present invention is not limited to this, and the air blowing modes of the left and right air ducts may be set to be different.

As shown in FIG. 3, for the embodiment with two air ducts 20, a vertical cross-flow fan 80 may be provided at the inlet of each air duct 20, and a heat exchanger 40 may be provided behind the two air ducts 20. Specifically, the heat exchanger 40 may be in a U shape with a forward opening, so as to enclose and block the two cross-flow fans 80 at the rear side and the lateral sides, so as to fully utilize the air volume of the two cross-flow fans 80, and to improve the heat exchange efficiency of the heat exchanger 40. Of course, the heat exchanger 40 may be formed in a flat plate shape or other shapes.

In alternative embodiments, the indoor unit of the air conditioner may include only one cross-flow fan 80 or other type of fan, and the fan supplies air to the two air ducts 20.

In alternative embodiments, it is also possible to provide the air conditioning indoor unit with two heat exchangers, each of which is disposed in one of the ducts 20.

In some embodiments, as shown in fig. 3, both sides of each air guiding element 50 and both inner walls of the air duct 20 may define an air outlet gap 201. The inner wall of the air duct 20 adjacent to the first air blowing opening 11 is tapered such that the flow cross section of the air duct 20 becomes gradually smaller in the airflow direction, in other words, the flow cross section of the air duct 20 becomes gradually smaller in the airflow direction adjacent to the first air blowing opening 11. In this way, the airflows flowing out of the two air outlet gaps 201 are converged into one flow outside the first air supply outlet 11 under the guidance of the tapered portion of the inner wall of the air duct 20, thereby achieving the effect of convergent air supply.

The end section 23 of the first duct wall and the turned-up edge 142 at the end of the front central panel 14 form the aforementioned tapered section of the duct 20. Specifically, the flange 142 is extended straight from the rear to the front, and the end section 23 is extended obliquely from the rear to the front in a direction approaching the flange 142 so as to be closer to each other, thereby forming a tapered section. When the adjusting section 25 of the second air duct wall rotates to a position between the first air supply outlet 11 and the extended air supply part 141, the end of the adjusting section 25 abuts against the flange 142. It is also possible to have the conditioning segment 25 progressively farther from the transverse center of the casing 10 from the rear to the front, so that the duct section defined by the conditioning segment 25 and the end segment 23 of the first duct wall is also a tapered section.

Due to the addition of the air guide 50, the flow cross section of the air outlet gap 201 is necessarily smaller than the original flow cross section of the air duct 20, which makes the air flow velocity faster. The high-speed air flow is gradually converged towards the center direction of the air flow in the outward flowing process under the guide of the gradually-reduced inner wall of the air duct 20 and is converged into one air flow, so that the wind power is very strong, the air supply distance is longer, the requirements of the indoor unit of the vertical air conditioner on long-distance air supply and strong air supply are met, the air supply range is larger, the refrigerating/heating speed of each part of the indoor space is more uniform, and the human body feels more comfortable.

In the embodiment of the present invention, the flow guiding element 50 not only defines the air outlet gap 201 with the inner wall of the air duct 20 to play a role of increasing the wind speed, but also can force the airflow to flow toward the air outlet gap 201, so as to force the airflow to be converged and guided by the tapered inner wall of the air duct 20, thereby forming a final converged air supply effect.

In some embodiments, as shown in fig. 3, the cross-sectional outer contour of each flow guide 50 may be an olive shape or an oval shape, and the two tips thereof face the inner walls of the air duct 20. The olive-shaped and the oval-shaped whole bodies are both formed by two convex curved surfaces, and the joint between the two large curved surfaces forms two tips. The convex curved surface faces the inside of the air duct 20, and the convex curved surface is used to smoothly disperse the airflow to two lateral tips of the air guiding element 50, that is, two air outlet gaps 201. The other convex curved surface faces the first air supply outlet 11, and the air flow can guide the air flow at the two air outlet gaps 201 to flow along the surface of the convex curved surface towards the center direction of the convex curved surface under the action of the coanda effect, and the convergence of the two air flows is facilitated.

In some embodiments, each deflector 50 is translatably mounted to the casing 10 to be translatably close to or far from the first air blowing opening 11, thereby adjusting the air output of the air outlet gap 201. Adjusting the air output of the air outlet gap 201 includes adjusting the air outlet gap 201 to 0. Specifically, the flow guiding element 50 is located behind the first air blowing opening 11, and since the flow cross section of the air duct 20 at the first air blowing opening 11 is gradually reduced, when the flow guiding element 50 is moved backwards, the distance between the flow guiding element 50 and the inner wall of the air duct 20 is increased, so that the air outlet gap 201 is increased. When the flow guide member 50 is moved forward, the distance between the flow guide member 50 and the inner wall of the air duct 20 is reduced, so that the air outlet gap 201 is reduced. When the diversion element 50 moves forward to make its two transverse ends abut against the inner wall of the air duct 20, the air outlet gap 201 disappears, and the first air outlet 11 is closed. The wind power can be improved by enlarging the wind outlet gap 201, and quick refrigeration/heating is realized; wind power is reduced by adjusting the small air outlet gap 201, natural wind is simulated, and the air flow comfort degree is higher. The air conditioner operates in a refrigeration mode, and when the old, children, pregnant women and other people who cannot bear strong refrigeration exist indoors, the air conditioner can selectively reduce wind power to operate.

As shown in fig. 7, the guide 50 is mounted to the cabinet 10 by a rack and pinion mechanism. Specifically, the rack and pinion structure includes a motor 71, a pinion 72, and a rack 73. The motor 71 drives the gear 72 to rotate. The gear 72 is engaged with a rack 73, and the rack 73 is fixed to the bottom of the deflector 50. In some embodiments, each baffle 50 may be a hollow structure. In this manner, the baffle 50 is made lighter in weight, facilitating its translation.
