As shown in fig. 1 to 7, a wall-mounted air conditioning indoor unit according to an embodiment of the present invention may generally include a casing 10 and an air duct 20.
An air outlet 12 is formed at the bottom of the front side of the casing 10, and a plurality of first air dispersing holes 13 are formed in a region of the bottom wall 101 of the casing 10 adjacent to the air outlet 12. The air outlet 12 is open forward and downward, a front edge of the bottom wall 101 of the housing 10 constitutes a lower edge (also a rear edge) of the air outlet 12, and the area where the first air dispersing holes 13 are located is adjacent to the front edge of the bottom wall 101.
The air duct 20 is formed in the housing 10 and is communicated with the air outlet 12 for guiding the air flow to the air outlet 12. The supply air flow is usually heat exchange air that exchanges heat with the heat exchanger 30, and may be fresh air flow. For example, a wall-mounted air conditioning indoor unit may be an indoor part of an air conditioner that performs cooling/heating using a vapor compression refrigeration cycle. 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.
As shown in fig. 3 and 7, the air chute 20 may be defined by a front wall 22 (i.e., volute tongue) and a rear wall 21. The rear wall 21 of the air duct 20 is provided with a plurality of second air dispersing holes 14, so as to allow part of the air to flow through the plurality of second air dispersing holes 14, enter the space between the rear wall 21 of the air duct 20 and the bottom wall 101 of the housing 10, and then blow into the room from the space through the plurality of first air dispersing holes 13. The opening area of the second air dispersing holes 14 is close to the air outlet 12, so that the second air dispersing holes are closer to the first air dispersing holes 13, and air supply airflow can enter the first air dispersing holes 13 quickly.
The utility model discloses among the wall-hanging air conditioning indoor set, a plurality of first scattered wind holes 13 have been seted up to diapire 101 of casing 10, have seted up a plurality of second scattered wind holes 14 at the back wall 21 in wind channel 20, can have the no wind sense air supply of degree of depth effect, realize comfortable air supply.
Specifically, when the wall-mounted air conditioner indoor unit is turned on and operated, and the air outlet 12 is opened, the air supply flow in the air duct 20 is blown to the air outlet 12, and a main body of the air supply flow is blown to the indoor through the air outlet 12, so that cooling/heating of the indoor environment is realized. The other part of the main part of the supplied air flow enters the space between the rear wall 21 of the air duct and the bottom wall 101 of the housing through the second air dispersing holes 14, and is blown into the room through the first air dispersing holes 13 from the space. In the process, the part of the air flow is scattered by the second air scattering holes 14 and the first air scattering holes 13 in sequence, so that the air flow becomes softer, a non-wind-feeling effect is achieved, discomfort caused by that cold air or hot air is blown to a human body intensively is avoided, and comfortable air supply of the air conditioner is realized. In addition, when the air flow passes through the second air dispersing holes 14 and the first air dispersing holes 13 in sequence, the air flow is dispersed twice and then blown into the room, the softness of the air flow is further enhanced, and the non-wind effect is stronger.
The utility model discloses among the wall-hanging air conditioner indoor set, because a plurality of first scattered wind hole 13 are located on the diapire 101 of casing 10, can vertical air supply downwards, also compensatied the defect that traditional air outlet is unfavorable for vertical air supply downwards. In the heating mode, air is vertically blown downwards through the first air dispersing holes 13, so that the temperature of the area right below the indoor unit of the wall-mounted air conditioner is increased more quickly.
When the outlet 12 is closed (for example, closed by the external air deflector), all of the blowing air is forced to flow into the plurality of second air-dispersing holes 14, so that the full-air-volume non-wind-sensation blowing effect is achieved.
In some embodiments, as shown in fig. 4 and 5, the rear wall 21 of the air chute 20 may be made to include an outlet section 201 and a main section 202. Wherein, the outlet section 201 is provided with the plurality of second air dispersing holes 14. Moreover, the outlet section 201 is connected to the air outlet 12 and is an integral piece with the bottom wall 101 of the housing 10, so as to simplify the manufacturing process thereof. For example, the outlet section 201 may be formed by bending the front end of the bottom wall 101 of the housing 10 upward and rearward. The main section 202 abuts against the outlet section 201. I.e. the lower end of the main body section 202 abuts the upper end of the outlet section 201. The main body section 202 is typically a volute.
Further, as shown in fig. 4 and 5, the front end of the main body section 202 may be bent downward to form a baffle 2021. The baffle 2021 extends at a lower end to the bottom wall 101 of the casing 10 to define, together with the outlet section 201 and the bottom wall 101 of the casing 10, a flow-passing chamber 15 communicating with the first plurality of air-dispersing holes 13 and the second plurality of air-dispersing holes 14. In this way, the air flow enters the flow passing cavity 15 at a low speed through the second air dispersing holes 14, stays and diffuses in the flow passing cavity 15, the air speed and the air pressure are further reduced, and then the air flow flows out through the first air dispersing holes 13, the air speed and the air pressure are reduced again, and the air flow is softer.
In some embodiments, the arrangement density and number of the plurality of first air dispersing holes 13 may be greater than those of the plurality of second air dispersing holes 14. The air flow is broken up by the second air-dispersing holes 14 and then flows to the first air-dispersing holes 13, and then is blown out through the first air-dispersing holes 13 relatively smoothly, so as to avoid the over-large wind resistance and the over-small wind quantity caused by two-time blocking.
The included angle between the air inlet direction of each second air dispersing hole 14 and the air outlet direction of the air duct 20 can be smaller than 60 degrees, and further the included angle can be smaller than 45 degrees, so that the air supply airflow can smoothly enter the second air dispersing holes 14.
As shown in fig. 2 and 4, the first air-dispersing holes 130 may be arranged in a matrix form. The second air-dispersing holes 14 form a plurality of air-dispersing areas arranged along the transverse direction of the casing 10, for example, two air-dispersing areas are provided, so that the area between the two air-dispersing areas can be used for installing the rotating shaft of the inner air deflector or the outer air deflector 50. The second air-dispersing holes 14 in each air-dispersing area are arranged in a matrix form. In addition, the first and second air dispersing holes 13 and 14 may be circular holes, kidney-shaped holes, square holes, elliptical holes, triangular holes, polygonal holes, or other openings of various shapes.
In some embodiments of the present invention, as shown in fig. 1 to 5, the wall-mounted air conditioner indoor unit further includes an inner air deflector 60 and an outer air deflector 50.
The outer air guide plate 50 is rotatably installed to the housing 10 for opening or closing the air outlet 12. Of course, the outer wind deflector 50 may also have a function of guiding the air blowing direction of the air outlet 12 up and down. It will be appreciated that the axis of rotation of the outer air deflectors 50 is parallel to the transverse direction of the casing 10, which transverse direction of the casing 10 has been indicated in the relevant figures.
The inner wind deflector 60 is rotatably installed inside the air outlet 12 for guiding the air outlet direction of the air outlet 12. The outer air guiding plate 50 is mainly used for opening and closing the air outlet 12, the inner air guiding plate 60 is located inside the outer air guiding plate 50, and when the outer air guiding plate 50 is in a state of closing the air outlet 12, the inner air guiding plate 60 is shielded inside the casing 10. When the outer air guiding plate 50 opens the air outlet 12, the inner air guiding plate 60 is used for guiding the air outlet direction of the air outlet 12, including swinging the air up and down.
In some embodiments, the inner air deflector 60 is configured to direct the supply airflow toward the second air discharge hole 14. As can be seen from the above, when the air outlet 12 is in the closed state, the air flow will flow to the second air dispersing holes 14. At this time, the inner air guiding plate 60 guides the blowing air flow toward the second air dispersing hole 14, so that the blowing air flow flows more smoothly toward the second air dispersing hole 14, and does not get into the second air dispersing hole 14 after rushing to the inner side of the outer air guiding plate 50 and cause a large pressure loss by being bent.
In some embodiments, as shown in fig. 3 and 4, both side surfaces of the inner air deflection plate 60 are formed with a plurality of spherical recesses 61. This makes inner air deflector 60 also carried out the vortex to the air supply air current when the wind-guiding, makes it more dispersed, has improved the comfort level of air supply air current. The inner air deflector 60 is matched with the first air dispersing hole 13 and the second air dispersing hole 14, and the air flow is comfortable and processed by utilizing different structures, so that the air flow is more comfortable, and the use experience of a user is improved.
In some embodiments, the wall-mounted air conditioning indoor unit may further include 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 plurality of second air dispersing holes 14 and the plurality of first 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.
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.
