The utility model provides a vertical air-conditioning indoor unit. An indoor unit of an upright air conditioner is an indoor part of the air conditioner for conditioning indoor air, such as cooling/heating, dehumidifying, introducing fresh air, and the like.

Fig. 1 is a schematic structural view of a vertical air conditioner indoor unit according to an embodiment of the present invention; fig. 2 is a schematic front view of the indoor unit of the floor type air conditioner shown in fig. 1; fig. 3 is an enlarged sectional view taken along line a-a of the indoor unit of the stand type air conditioner shown in fig. 2.

As shown in fig. 1 to 3, a vertical air conditioner indoor unit according to an embodiment of the present invention may generally include a cabinet 10 and at least one air 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 each air duct 20 is provided with a vertical bar-shaped first air supply outlet 11. 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 cabinet 10 is formed with an air inlet 13, and the air inlet 13 may be disposed at a rear surface of the cabinet 10 for introducing indoor air flow. In some embodiments, the indoor unit of the vertical 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 of the guiding members 50 is a vertically extending column, and each of the guiding members 50 is disposed at one of the first air blowing openings 11 to define an air outlet gap 201 with an inner wall of the air duct 20 adjacent to the first air blowing opening 11, so that the air flow at the first air blowing 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. Or, only one side of each flow guide element 50 and the inner wall of one side of the air duct 20 may define an air outlet gap 201, and the other side 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 utility model discloses among the vertical air conditioner indoor set, because first supply-air outlet 11 department is provided with water conservancy diversion piece 50, the air-out clearance 201 between water conservancy diversion piece 50 and the 20 inner walls in wind channel of air current is blown off, makes the air current can not directly blow the human body with the big amount of wind for the human body feels 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 deflectors 50 may be made to change its position (including translation, rotation, or compound movement) to adjust the size of the air outlet gap 201 to change its flow area (including adjusting the flow area to 0), thereby adjusting the wind power of the first air blowing opening 11. Specifically, the wind power can be increased by enlarging the air outlet gap 201 to more rapidly cool/heat; wind power is reduced by adjusting the small air outlet gap 201, natural wind is simulated, and the air flow comfort degree is higher.

In some embodiments, as shown in fig. 1 to 3, each air duct 20 is further provided with a second air supply outlet 12, and the second air supply outlet 12 has the same function as the first air supply outlet 11 and is used for discharging airflow (heat exchange airflow or fresh air airflow, etc.) in the air duct 20 to the room. 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 vertical air conditioner indoor unit can supply air with small air volume through the first air supply outlet 11 and supply air with large air volume through the second air supply outlet 12, and multiple air supply modes can be obtained by matching the two air supply modes. For example, both of the supply ports may be opened simultaneously or only one of the supply ports may be opened.

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 to arrange the plurality of first air blowing ports 11 or the plurality of second air blowing ports 12 in the vertical direction.

Further, as shown in fig. 1 to 3, 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 lateral direction) of the cabinet 10. It is understood that each duct 20 has a first supply outlet 11 and a second supply outlet 12. The first air supply outlets 11 of the two air ducts 20 are open forward, and the second air supply outlets 12 of the two air ducts 20 are open toward the two lateral sides of the casing 10. 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.

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. In a word, the two air supply openings are matched, so that the air supply angle is larger.

Fig. 4 is a schematic view showing the stand type air conditioning indoor unit shown in fig. 3 in a state where the first air blowing port 11 is closed and the second air blowing port 12 is opened; fig. 5 is a schematic view of the stand type air conditioning indoor unit shown in fig. 3 in a state where both the first air blowing port 11 and the second air blowing port 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 selectively discharged from the first air outlet 11, so that cool air supply experience without cold air is realized, and discomfort of a human body caused by large air flow of cold air is avoided, as shown in fig. 3. In the heating mode, the first air supply outlet 11 does not supply air or a small amount of air, and the second air supply outlets 12 on two sides supply air, so that 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 turn forwards after meeting a wall body, thereby forming an air supply effect of surrounding by 180 degrees, and enabling a user to feel stronger heating, and be more comfortable, as shown in fig. 4. When the indoor unit of the floor air conditioner is in the off state, the first air supply outlet 11 and the second air supply outlet 12 are both in the off state, as shown in fig. 5. Of course, it should be understood that the above air supply modes selected for two working conditions are only some preferred solutions, the air conditioner can also select the second air supply outlet 12 to supply air during cooling, and can also select the first air supply outlet 11 to supply air during heating, the utility model discloses do not do any restriction to the combination mode of air conditioner operating mode and air supply mode. In the embodiment of fig. 3 to 4, 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.

In some embodiments, at least one air deflector 60 is disposed at each second air blowing opening 12 for opening and closing the second air blowing opening 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 air blowing port 12 to guide the direction of the wind 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.

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 deflector 50 and both side inner walls of the air duct 20 may define an air outlet gap 201. The inner wall of the air duct 20 near the first air blowing opening 11 is tapered so that the flow cross section of the air duct 20 becomes gradually smaller along the airflow direction, in other words, the flow cross section of the air duct 20 becomes gradually smaller along the airflow direction near 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. For example, in the embodiment shown in fig. 3 in which the first air blowing port 11 and the second air blowing port 12 are provided, the duct 20 is formed of the first duct wall and the second duct wall 22. The first air duct wall includes a rear section 21 and a front section 23, and a front end of the rear section 21 and a rear end of the front section 23 are spaced apart from each other to form the second blowing port 12. The front section 23 and the front end of the second air duct wall 22 form the aforementioned tapered section of the air duct.

Due to the addition of the flow 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 tapered inner wall of the air duct 20 to form one air flow, so that the wind power is very strong, the air supply distance is farther, 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.

The embodiment of the utility model provides an in, air-out clearance 201 has not only been injectd with the inner wall in wind channel 20 to water conservancy diversion spare 50, plays the effect that promotes the wind speed, also can force the air current to flow towards air-out clearance 201 just to force the air current to accept the polymerization guide of wind channel 20 convergent form inner wall, form final polymerization 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 diversion element 50 is moved forward, the distance between the diversion element 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 air 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.

Fig. 6 is an enlarged sectional view of C-C of the indoor unit of the stand type air conditioner shown in fig. 2.

As shown in fig. 6, the deflector 50 is mounted to the casing 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.

Thus, 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 in detail herein, many other variations and modifications can be made, consistent with the principles of the invention, which are directly determined or derived from the disclosure herein, without departing from the spirit and scope of the invention.
