The invention does not limit the style of the indoor unit of the air conditioner, and can be a wall-mounted type, a vertical type, a ceiling type and the like, and fig. 1 to 18 show the embodiment of the indoor unit of the vertical type air conditioner.
Fig. 1 to 5 illustrate some blowing modes of an air conditioning indoor unit according to a first embodiment of the present invention, fig. 6 to 11 illustrate some blowing modes of an air conditioning indoor unit according to a second embodiment of the present invention, and fig. 12 to 18 illustrate some blowing modes of an air conditioning indoor unit according to a third embodiment of the present invention. It should be noted that the above three embodiments are only some preferred embodiments of the present invention, and only some air supply modes of the embodiments are illustrated in the drawings, and some embodiments and some air supply modes are not explicitly listed.
The air conditioner indoor unit according to the embodiment of the present invention includes a cabinet 10, and the cabinet 10 defines at least one duct 20. The casing 10 according to the embodiment of the present invention 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. A plurality of air blowing ports are formed side by side at an outlet of each air duct 20 for blowing the conditioned air flow inside the cabinet 10 toward the indoor environment. In the first embodiment, the plural air blowing ports refer to the first air blowing port 11 and the second air blowing port 12, and in the second and third embodiments, the plural air blowing ports refer to the first air blowing port 11, the second air blowing port 12, and the third air blowing port 13. The adjusting air flow can be cold air produced by the indoor unit of the 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 housing 10 may be formed with an air inlet for introducing indoor air flow. In some embodiments, the indoor unit of the 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, after heat exchange with the heat exchanger 40 is completed, the indoor air enters the air duct 20 under the action of the fan, and then is blown to the indoor environment through the air supply outlet, so that the indoor environment air is regulated.
Each duct 20 is defined by first and second duct walls 21, 22 spaced apart. That is, the space between the two duct walls constitutes one duct 20. The outlet end position of the first duct wall 21 and/or the second duct wall 22 is adjustable so that the duct 20 is selectively in communication with one or more of the plurality of supply air ports. That is, only the outlet end position of the first duct wall 21 may be adjustable, only the outlet end position of the second duct wall 22 may be adjustable, or both the outlet end positions of the duct walls may be adjustable. The outlet end of the air duct wall is not fixed and is adjustable, the direction of the outlet of the air duct 20 can be changed to lead the outlet to face different air supply outlets, and the size of the outlet of the air duct 20 can also be changed to change the number of the air supply outlets facing the outlet.
The air supply adjusting modes of the air conditioner indoor unit are rich, the air conditioner indoor unit can adjust different air supply modes according to different operation conditions and different user requirements, corresponding air supply outlets are started, other air supply outlets are stopped, the overall wind direction, the air volume and the like of the air conditioner indoor unit are changed, and a user can obtain better air supply experience. For example, the activated air supply outlet is increased or decreased according to the air volume requirement, the specific air supply outlet is activated according to the requirement of a user, and the specific air supply outlet can be an air supply outlet capable of blowing air in a micropore mode, a convergent air supply outlet with a longer air supply distance, an air supply outlet with a special orientation and the like.
In some embodiments, the first duct wall 21 may be made to include, in the direction of airflow, a first main body segment 211 and a first adjustment segment 212 that are rotationally connected (axis of rotation x 1); and/or the second duct wall 22 comprises, in the direction of the gas flow, a second main segment 223 and a second regulation segment 224 which are rotationally connected (axis of rotation x 2). The first main body section 211 and the first regulation section 212 are joined to form the complete first air duct wall 21, and the first main body section 211 is located on the upstream side of the air flow compared to the first regulation section 212. The second main body segment 223 and the second regulation segment 224 are joined to form the complete second air duct wall 22, and the second main body segment 223 is located on the upstream side of the air flow compared to the second regulation segment 224. "and/or" means: it is sufficient that one of the two conditions is satisfied (refer to the first embodiment), or both of the two conditions are satisfied (refer to the second and third embodiments). In this way, the air conditioning indoor unit can adjust the outlet end position of the first air duct wall 21 and/or the second air duct wall 22 by rotating the first adjusting section 212 and/or the second adjusting section 224, so that the air duct 20 is selectively communicated with one or more of the plurality of air blowing openings. Such a first duct wall 21/second duct wall 22 can be regarded as a flexible structure, which is very clever and very convenient to adjust. Of course, the rotation of the first and second adjustment segments 212, 224 may be driven by respective motors.
Some alternative blowing modes of the air conditioning indoor unit according to the first embodiment of the present invention will be described with reference to fig. 1 to 5.
Fig. 1 is a schematic view of an air conditioning indoor unit according to a first embodiment of the present invention when both supply ports are closed;
fig. 2 is a schematic view of the air conditioning indoor unit shown in fig. 1 when the duct 20 communicates only with the first supply port 11; fig. 3 is a schematic view of the air conditioning indoor unit shown in fig. 2 after the air guide element 50 moves backward to enlarge the air outlet gap 201; fig. 4 is a schematic view of the indoor unit of the air conditioner shown in fig. 1 when the duct 20 communicates with two air supply ports; fig. 5 is a schematic view of the air conditioning indoor unit shown in fig. 4 when the guide 50 opens the first blowing port 11.
As shown in fig. 1 to 5, two air blowing ports, namely, a first air blowing port 11 and a second air blowing port 12, are formed at the outlet of each air duct 20, and a third air duct wall 23 is used as a boundary between the two air blowing ports. The first air duct wall 21 includes a first main body section 211 and a first regulation section 212 rotatably connected in the air flow direction. The outlet end of the second air duct wall 22 is not adjustable, and the outlet end is connected to the end (shown as the left end of the first air supply outlet 11) of the first air supply outlet 11 far from the second air supply outlet 12, so that when the end (forming the outlet end of the first air duct wall 21) of the first adjusting section 212 is connected to the end of the second air supply outlet 12 far from the first air supply outlet 11, the air duct 20 communicates the first air supply outlet 11 and the second air supply outlet 12, as shown in fig. 1, 4 and 5; when the third air duct wall 23 is connected to the end of the first adjusting section 212, the air duct 20 is communicated only with the first supply port 11, as shown in fig. 2 and 3.
In some alternative structures, as shown in fig. 1 to 5, a diversion member 50 is disposed at the first air blowing opening 11, and an air outlet gap 201 is defined between the diversion member 50 and an inner wall of the air duct 20 adjacent to the first air blowing opening 11, so that the airflow at the first air blowing opening 11 is blown to the indoor environment through the air outlet gap 201. It should be noted that the third air duct wall 23 is used only for separating the two supply ports, and may be significantly smaller than the first air duct wall 21 and the second air duct wall 22, but still defined as "air duct walls", and when the end of the first adjustment section 212 is connected to the third air duct wall 23, the third air duct wall 23 also has the function of defining the air duct 20, but only a short section of the air duct 20 adjacent to the first supply port 11. The wall surface of the third air duct wall 23 facing the air guiding element 50 also belongs to the aforementioned "inner wall of the air duct 20" and is also used for defining the aforementioned "air outlet gap 201". As do the subsequent fourth 24 and fifth 25 duct walls. The air flow is blown out through the air outlet gap 201, so that the air flow can not blow the human body directly with large air quantity, and 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.
Specifically, as shown in fig. 1 to 5, the casing 10 is made to extend in a vertical column shape, that is, the indoor air conditioner is a vertical indoor air conditioner, the first air supply outlet 11 is made in a vertical bar shape, and the air guide member 50 is made in a column shape extending vertically. Both sides of the air guiding element 50 and both side inner walls of the air duct 20 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 the 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 the air outlet gap 201 is not formed, and air cannot be exhausted. Of course, the second supply port 12 is also preferably vertical bar-shaped.
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 define an air outlet gap 201, and 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 gradually decreases in the air flow direction. In other words, the flow cross section of the air duct 20 becomes gradually smaller in the air flow direction adjacent to the first supply outlet 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 part of the inner wall of the air duct 20, so as to form a converged air supply effect.
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 airflow is gradually converged towards the center direction of the airflow in the outward flowing process under the guidance of the tapered inner wall of the air duct 20 to form one airflow, so that the wind power is very strong, the air supply distance is farther, the requirements of an indoor unit of an 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 air guiding element 50 not only defines an air outlet gap 201 with the inner wall of the air duct 20 to play a role of increasing the wind speed, but also just forces the airflow to flow towards the air outlet gap 201 so as to force the airflow to be subjected to the polymerization and guidance of the tapered inner wall of the air duct 20, thereby forming the 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.
Further, each of the air deflectors 50 may be changed in 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 deflector 50 closes the first air blowing opening 11), 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 wind outlet gap 201 to be small (adjusted from the state of fig. 2 to the state of fig. 3), natural wind is simulated, and the air flow comfort is higher.
Specifically, for example, as shown in fig. 1 to 5, each of the air deflectors 50 is translatably mounted to the casing 10 to translationally approach to or depart from the first air outlet 11, so as to adjust the air output of the air outlet gap 201. Specifically, the baffle 50 may be mounted to the housing 10 by a motor + rack and pinion mechanism for driving translation thereof. 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 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.
The second air supply outlet 12 may be provided with an air guide flap 60 for opening and closing the second air supply outlet 12 and/or guiding the air outlet direction thereof. The first air blowing opening 11 and the second air blowing opening 12 may be opened forward so that the air guide flap 60 guides the air to blow forward, leftward or rightward. Of course, the first air supply outlet 11 and the second air supply outlet 12 can be oriented differently, for example, one facing forward and the other facing left (or right), and detailed description thereof is omitted. In addition, instead of the air guide flap 60, an air outlet structure such as an air outlet grille or a micro-perforated plate may be provided at the second air outlet 12.
In summary, the air conditioning indoor unit according to the first embodiment of the present invention has the first air outlet 11 as the collective air outlet and the second air outlet 12 as the regular air outlet. The indoor unit of the air conditioner can select different air supply modes according to different working conditions. For example, the air can be selectively discharged from the first air outlet 11, and the air is not discharged from the second air outlet 12, as shown in fig. 2; or further translating the diversion element 50 to reduce the air outlet gap 201 to reduce the air volume, as shown in fig. 3; or the air duct 20 is communicated with the two air supply outlets, but the first air supply outlet 11 is closed by the diversion piece 50, so that only the second air supply outlet 12 is used for supplying air, as shown in fig. 4; alternatively, the duct 20 may communicate with the two air supply ports, but the first air supply port 11 may be closed by the air guide 50 so that both the first air supply port 11 and the second air supply port 12 are used for supplying air. When the air conditioning indoor unit is in a stop state or a standby state, as shown in fig. 1, the air guide flap 60 closes the second air supply outlet 12, and the air guide member 50 closes the first air supply outlet 11, so that the casing 10 is closed. At this time, the position of the first adjustment segment 212 is not important.
Some alternative blowing modes of the air conditioning indoor unit according to the second embodiment of the present invention will be described with reference to fig. 6 to 11.
As shown in fig. 6 to 11, the difference from the first embodiment is that in the second embodiment, three air blowing ports are formed at the outlet of each air duct 20, namely, a first air blowing port 11, and a second air blowing port 12 and a third air blowing port 13 which are respectively located on both sides thereof, the first air blowing port 11 and the second air blowing port 12 are demarcated by a third air duct wall 23, and the third air blowing port 13 and the first air blowing port 11 are demarcated by a fourth air duct wall 24. The first air duct wall 21 includes a first main body segment 211 and a first regulation segment 212 (rotation axis x1) which are rotatably connected in the air flow direction, and the second air duct wall 22 includes a second main body segment 223 and a second regulation segment 224 (rotation axis x2) which are rotatably connected in the air flow direction.
When the third air duct wall 23 and the fourth air duct wall 24 are connected to the end of the first adjusting section 212 (the outlet end constituting the first air duct wall 21) and the end of the second adjusting section 224 (the outlet end constituting the second air duct wall 22), respectively, the air duct 20 is communicated only with the first air blowing port 11, as shown in fig. 7. When the end of the first adjusting section 212 is connected to the end (left end in the figure) of the second air blowing port 12 far from the first air blowing port 11 and the second adjusting section 224 is connected to the fourth air duct wall 24, the air duct 20 communicates the first air blowing port 11 and the second air blowing port 12, as shown in fig. 8. When the end of the first adjusting section 212 is connected to the third air duct wall 23 and the end of the second adjusting section 224 is connected to the end (right end in the figure) of the third air blowing port 13 away from the first air blowing port 11, the air duct 20 communicates the first air blowing port 11 and the third air blowing port 13, as shown in fig. 9. When the end of the first adjusting section 212 is connected to the end (left end in the figure) of the second air blowing port 12 away from the first air blowing port 11, and the end (right end in the figure) of the second adjusting section 224 is connected to the end (right end in the figure) of the third air blowing port 13 away from the first air blowing port 11, the air duct 20 is made to communicate with the first air blowing port 11, the second air blowing port 12, and the third air blowing port 13, as shown in fig. 6, 10, and 11.
Of course, as shown in fig. 6 to 11, in the second embodiment of the present invention, the flow guiding member 50 may be disposed at the first air blowing opening 11. The third air blowing port 13 may be provided with an air guide flap 60 for opening and closing the third air blowing port and/or guiding the wind direction. The above definitions of the air guiding element 50 and the air guiding swing blade 60 in the first embodiment are also applicable to the second embodiment, and therefore, the detailed description thereof is omitted.
In some embodiments, 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 casing 10. Each air duct 20 and each air supply outlet corresponding thereto may be regarded as one air supply group, and the two air supply groups may be symmetrically disposed in the lateral direction of the casing 10, or may be asymmetrically disposed.
For example, as shown in fig. 12 to 18, the third embodiment of the present invention illustrates an alternative structure of two air ducts 20 disposed in the casing 10. The third embodiment of the present invention is different from the second embodiment in that one air duct 20 and its respective air blowing ports of the second embodiment are mirror-copied to constitute a structure of two air ducts 20+ six air blowing ports on the left and right. The two third blowing ports 13 are demarcated by a fifth duct wall 25. When the second conditioning segment 224 of the second duct wall 22 of each duct 20 abuts the fifth duct wall 25, the corresponding third supply air outlet 13 is activated.
The air supply mode of the third embodiment is more diversified due to the provision of the two air ducts 20 and the six air supply ports, including but not limited to the following modes. As shown in fig. 12, each of the air blowing ports may be closed. As shown in fig. 13, both the air ducts 20 are communicated with the first air blowing port 11, and the air is supplied from the first air blowing port 11 in a converging manner. As shown in fig. 14, both the air ducts 20 are made to communicate with the first supply port 11 and the third supply port 13. As shown in fig. 15, one air duct 20 is communicated with only the first air supply port 11, and the other air duct 20 is communicated with the first air supply port 11 and the third air supply port 13. As shown in fig. 16, one air duct 20 communicates with only the first air blowing port 11, and the other air duct 20 communicates with the first air blowing port 11, the second air blowing port 12, and the third air blowing port 13. As shown in fig. 17, one air duct 20 communicates only with the first air outlet 11 and the third air outlet 13, and the other air duct 20 communicates with the first air outlet 11, the second air outlet 12, and the third air outlet 13. As shown in fig. 18, each duct 20 is communicated with respective three air supply ports. But the two first blowing ports 11 are closed by the guide member 50.
It can be understood that the structure of the single air duct and the double air supply openings of the first embodiment can also be mirror-copied to form a structure of the double air duct and the four air supply openings.
As shown in fig. 1 to 18, a cross-flow fan 80 may be provided at the inlet of each air duct 20 in a vertical arrangement, and a heat exchanger 40 may be provided behind the air duct 20. Specifically, the heat exchanger 40 may be in a U shape with an opening facing forward, so as to enclose and block the 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.
Thus, it should be appreciated by those skilled in the art that while a number of exemplary embodiments of the invention have been illustrated and described in detail herein, many other variations or modifications consistent with the principles of the invention may be directly determined or derived from the disclosure of the present invention without departing from the spirit and scope of the invention. Accordingly, the scope of the invention should be understood and interpreted to cover all such other variations or modifications.
