Detailed Description

A wall-mounted air conditioning indoor unit according to an embodiment of the present invention will be described with reference to fig. 1 to 9. Where the orientations or positional relationships indicated by the terms "front", "back", "upper", "lower", "top", "bottom", "inner", "outer", "lateral", etc., are based on the orientations or positional relationships shown in the drawings, they are merely for convenience of description and to simplify the description, and do not indicate or imply that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore should not be construed as limiting the invention.

Fig. 1 is a schematic structural view of a wall-mounted air conditioner indoor unit according to an embodiment of the present invention when an air deflector body is in an extended state; fig. 2 is a schematic structural view of a wind deflector of the wall-mounted air conditioner indoor unit shown in fig. 1; fig. 3 is an enlarged view at M of fig. 2.

As shown in fig. 1 to 3, a wall-mounted air conditioning indoor unit according to an embodiment of the present invention may generally include a casing 10 and an outer air guide plate 50. The housing 10 is provided with an air outlet 12 for exhausting the air flow. The supply air flow is usually a heat exchange air flow which exchanges heat with the heat exchanger, and can also be a fresh air flow. The outer air deflection 50 includes a mounting arm 52 and an air deflection body 51. The mounting arm 52 is mounted to the housing 10. The air deflection body 51 is telescopically mounted to the mounting arm 52. The mounting arm 52 can rotate relative to the housing 10 to drive the air deflector body 51 to open and close the air outlet 12. Of course, a motor is mounted within the housing 10 for driving the rotation of the mounting arm 52.

The outer air deflection plate 50 is further configured to: when the mounting arm 52 is at the closing angle, the air deflector body 51 is in the retracted state for closing the air outlet 12; or in an extended state that extends outward of the outlet 12 to allow the blowing airflow to be blown out from between the edge of the air deflector body 51 and the edge of the outlet 12, as shown in fig. 1. When the wall-mounted air conditioning indoor unit is in a shutdown state, the air deflector body 51 is in a retracted state to close the air outlet 12. When the wall-mounted air conditioning indoor unit is in a power-on state, the air deflector body 51 may be in an extended state, or the mounting arm 52 may be rotated to an open angle, so that the air deflector body 51 opens the air outlet 12, and air is directly discharged from the air outlet 12.

The utility model discloses wall-hanging air conditioning indoor set has a no wind sense air supply mode, and under this mode, aviation baffle body 51 is in aforementioned state of stretching out, and the air supply air current outwards blows out through the interval between aviation baffle body 51 edge and the 12 edges of air outlet. Compared with the mode of directly discharging air from the air outlet 12, the air-discharging mode has the advantages that the airflow is more dispersed, the impact force is smaller, the human body cannot be directly blown, and the human body feels more comfortable.

In some embodiments, as shown in fig. 2 and 3, the end of the mounting arm 52 may be provided with a receptacle 522, and the wall of the receptacle 522 may be provided with a plurality of bayonets 523 arranged along the axial direction of the receptacle 522. An inserting rod 512 extends from the inner side of the air deflector body 51, and the inserting rod 512 has a retaining protrusion 513 protruding radially outward. The inserting rod 512 is inserted into the inserting hole 522 and the catching protrusion 513 is caught into one of the plurality of catching openings 523, so that the telescopic distance of the air deflection plate body 51 relative to the mounting arm 52 is adjusted by catching the catching protrusion 513 into a different catching opening 523. The structure of the outer air deflector 50 realizes manual adjustment of the telescopic distance of the air deflector body 51, does not need to arrange a complex driving mechanism, saves the cost, and avoids occupying a very narrow inner space of the shell 10. When the user needs to adjust the air deflector body 51 to the retracted state or the extended state, the outer air deflector body 51 is integrally rotated to the closed angle, and then the air deflector body 51 is manually pushed or pulled out. Of course, in some alternative embodiments, a linear motion mechanism may be designed to drive the telescopic motion of the air deflector body 51.

In some embodiments, as shown in fig. 1, at least one lateral side wall of the housing 10 may be provided with a plurality of first air dispersing holes 14 for discharging the air flow. It is preferable that both lateral side walls of the case 10 are provided with the first dissipation holes 14. Therefore, the air supply airflow can be blown forwards and can be blown to the left and right directions, so that the air outlet angle range is larger, the air supply airflow is more dispersed, the air supply airflow is more quickly and sufficiently fused with indoor air, the airflow is softer, and the requirement of a user on comfortable air supply of the air conditioner is met. The first plurality of air dispersing holes 14 may be elongated, as shown in fig. 1. In addition, the first air dispersing hole can also be a circular hole, an elliptical hole or other shapes.

Fig. 4 is a schematic bottom view of the wall-mounted air conditioning indoor unit shown in fig. 1; fig. 5 is an enlarged view of fig. 4 at a.

In some embodiments, the bottom wall 101 of the casing 10 may be provided with a plurality of second air dispersing holes 13 for discharging the air flow in the casing 10. Therefore, the air supply mode of the air conditioner is more diversified, the selection of a user is enriched, and the user experience is improved. For example, the air outlet 12 can be selectively opened, and the air is simultaneously discharged through the air outlet 12, the plurality of first air-dispersing holes 14 and the plurality of second air-dispersing holes 13, so that large-air-volume cooling/heating is realized. Alternatively, the air deflector body 51 may be adjusted to a retracted state to close the air outlet 12, and the plurality of first air-dispersing holes 14 and the plurality of second air-dispersing holes 13 may perform breeze air-out, thereby achieving a completely non-wind blowing effect. Or, when the air deflector body 51 is adjusted to the extended state, the plurality of first air-dispersing holes 14, the plurality of second air-dispersing holes 13 and the edge interval between the air deflector body 51 and the air outlet 12 perform breeze air-out together, so that not only the air supply comfort is ensured, but also the air volume is larger.

In addition, the wall-mounted air conditioner indoor unit can supply air downwards through the second air dispersing holes 13, and the defect that a traditional air outlet is not beneficial to supplying air downwards is overcome. In the heating mode of the wall-mounted air conditioner indoor unit, air is supplied downwards through the plurality of second air dispersing holes 13, so that the temperature of the area right below the wall-mounted air conditioner indoor unit is increased more quickly. As shown in fig. 5, the opening areas of the second air dispersing holes 13 may be adjacent to the edge of the air outlet 12.

The wall-mounted air conditioner indoor unit can further comprise a human detection sensor and a controller. The human body sensor is mounted on the casing 10 and used for detecting whether a human body enters the air outlet coverage range of the air outlet 12, and specifically, the human body sensor can be an infrared sensor. Based on this, an alternative non-wind-sensing control mode is as follows: when the human body sensor detects that the human body enters the air outlet coverage range, a human body sensing signal is formed, and the human body sensing signal is transmitted to the controller. The controller controls the outer air deflector 50 to close the air outlet 12, so that the air conditioner can completely supply air without wind sense through the first air dispersing holes 14 and the second air dispersing holes 13, and cold air or hot air is prevented from directly blowing to a human body. When the human body sensor detects that the human body leaves the air outlet coverage area, the controller controls the outer air deflector 50 to open the air outlet 12, and the air is normally supplied.

As shown in fig. 5, the second air dispersing holes 13 may be formed in a diamond shape as a whole. Compare in the circular micropore of conventional adoption, the embodiment of the utility model provides a rhombus hole edges and corners that adopts is more clear, and is stronger to the effect of breaing up of air current. Further, the plurality of second dissipating holes 13 may be arranged in a plurality of rows arranged in front and rear, and the second dissipating holes 13 in each row are arranged in the lateral direction of the casing 10 and communicate with each other. This structure increases the air volume of the second air dispersing holes 13 as a whole.

Fig. 6 is an enlarged cross-sectional view of the wall-mounted indoor unit of the air conditioner shown in fig. 1; FIG. 7 is an enlarged view at N of FIG. 6; fig. 8 is a schematic view showing a structure of a casing in the wall-mounted type air conditioning indoor unit of fig. 1; fig. 9 is an enlarged view of fig. 8 at B.

As shown in fig. 6 to 9, the wall-mounted air conditioning indoor unit further includes a guide portion 70 and an air duct 20. The flow guide portion 70 is located inside the bottom wall 101 of the casing 10, and defines a flow passage 701 communicating with the plurality of second air dispersing holes 13 together with the bottom wall 101 of the casing 10.

The air duct 20 is formed within the housing 10 and is defined by a rear wall 21 (or volute) and a front wall 22 (or tongue). The front end of the rear wall 21 is connected to the rear end of the flow guide portion 70 and is communicated with the flow passage 701, so as to guide the air flow to the air outlet 12 and the flow passage 701. The air flow entering the flow passage 701 is blown out through the plurality of second air dispersing holes 13.

The wall-mounted air conditioner indoor unit may be an indoor part of an air conditioner that performs cooling/heating using a vapor compression refrigeration cycle system. A heat exchanger 30 and a fan 40 are provided in the casing 10. The fan 40 may be a cross-flow fan, and under the action of the fan 40, the indoor air enters the casing 10 through the air inlet 11 at the top of the casing 10, completes forced convection heat exchange with the heat exchanger 30 to form heat exchange air, and then blows toward the air outlet 12 under the guidance of the air duct 20.

The flow guide 70 includes a passage fence 71 and a connection plate 72. Wherein the channel containment flaps 71 extend upwardly from the inside surface of the bottom wall 101 of the housing 10 for defining the aforementioned overflow channels 701 in cooperation with the bottom wall 101 of the housing 10. The passage fence 71 specifically includes a rear plate and left and right side plates extending forward from both lateral ends of the rear plate, and front ends of the two side plates are joined to the bottom wall 101 of the housing 10. The connecting plate 72 extends rearward from the top end of the passage fence 71 to meet the front end of the rear wall 21 of the air chute 20. In this embodiment, the passage enclosure 71 not only defines the flow passage 701 together with the bottom wall 101 of the casing 10, but also guides the flow of the supply air to the plurality of second air dispersing holes 13. The connecting plate 72 extends from the top end of the channel baffle 71 to connect with the front end of the rear wall 21 of the air duct 20, so that the connecting plate 72 is equivalent to an extension of the rear wall 21 of the air duct 20, which makes the connection transition between the rear wall 21 of the air duct 20 and the connecting plate 72 more natural and smooth without causing extra on-way resistance to the air flow.

In the above embodiment, the air flow is guided forward by the rear wall 21 of the air duct 20 and the connecting plate 72, and then bends downward to enter the flow passage 701, so that the bottom wall 101 of the housing 10, the rear wall of the passage baffle 71 and the rear wall 21 of the air duct 20 form a step surface. When the wall-mounted air conditioner indoor unit operates in a refrigeration mode, condensation at the positions of the second air dispersing holes 13 can be effectively prevented by the stepped surface structure, and condensed water is prevented from dripping out through the second air dispersing holes 13.

In some embodiments, as shown in fig. 8 to 9, the flow guides 70 are two in number and arranged in the lateral direction of the housing 10. The deflector 70 is an integral piece with the housing 10. The design makes the structure simpler on the one hand, has saved the assembly work in later stage, and on the other hand also makes the position of being connected of water conservancy diversion portion 70 and the diapire 101 of casing 10 not have any gap, can avoid the air supply air current to leak through the gap between the two and flow back to the inside of casing 10 (the inside in non-wind channel 20), causes cold volume/heat waste. Especially, when the outer air deflector 50 closes the air outlet 12, the air flow of the supply air is forced to flow to the flow passage 701 by the fan, the air pressure in the flow passage 701 is large, and if a gap exists between the air guide part 70 and the bottom wall 101 of the housing 10, a leakage problem is easily caused.

In some embodiments, as shown in fig. 3, the wall-mounted air conditioning indoor unit is further provided with an inner air deflector. The inner air guiding plate is located at the inner side of the outer air guiding plate, and when the outer air guiding plate 50 is in a state of closing the air outlet 12, the inner air guiding plate is shielded at the inner side of the casing 10. When the outer air guiding plate 50 opens the air outlet 12, the inner air guiding plate is used for guiding the air outlet direction of the air outlet 12, including swinging the air up and down.

The inner air deflector is configured to direct the supply air flow toward the flow passage 701. As can be seen from the above, when the air outlet 12 is in the closed state, the air flow will flow to the flow passage 701. At this time, the inner air deflector can guide the air flow toward the flow passage 701, so that the air flow can flow more smoothly toward the flow passage 701, and does not detour into the flow passage 701 after rushing to the inner side of the outer air deflector 50, thereby causing large pressure loss.

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. Accordingly, the scope of the present invention should be understood and interpreted to cover all such other variations or modifications.
