Optionally, the flow guide is an integral piece with the housing.
The wall-mounted air conditioner indoor unit is provided with an air outlet, and the bottom wall of the shell is provided with at least one strip-shaped breeze hole. When the air outlet is in an open state, the main body part of the air supply airflow (the air supply airflow is usually heat exchange air which exchanges heat with the heat exchanger) inside the shell is blown to the indoor from the air outlet, and the other part of the air supply airflow outside the main body part is blown out through the strip-shaped micro air holes, so that a micro air hole air supply effect is realized, the airflow is softer and has no wind sensation, and the comfortable air supply of the air conditioner is realized. When the air outlet is closed (for example, closed by an external air deflector), all the air supply airflow is forced to flow to the strip-shaped breeze holes, so that the strip-shaped breeze holes supply air with large air volume, and the effect of completely supplying air without wind sense is realized.
In addition, the wall-mounted air conditioner indoor unit can realize micropore air supply, and also can adjust the air outlet direction of the strip-shaped breeze hole by utilizing the plurality of guide blades, for example, the air outlet direction of the strip-shaped breeze hole can be kept away from a human body through the plurality of guide blades, so that cold air/hot air can be completely prevented from blowing people. In addition, the air outlet direction of the strip-shaped breeze holes can be adjusted by the air guide blades, and the air outlet quantity of the strip-shaped breeze holes can also be adjusted. In a word, the arrangement of the air guide blades enables air supply control to be further refined. Finally, the plurality of air guide blades also play a role in scattering the air flow supplied by the strip-shaped micro-air holes, so that the softness of the air flow is enhanced.
Furthermore, in the wall-mounted air conditioner indoor unit, the long-strip-shaped micro air holes are positioned on the bottom wall of the shell, so that air can be supplied vertically downwards, and the defect that the air is inconvenient to supply vertically downwards because the traditional wall-mounted air conditioner indoor unit only supplies air through the air outlet is overcome. Particularly, when the air conditioner is in a heating mode, the long-strip-shaped micro air holes are used for vertically and downwards supplying air, so that the temperature of the area right below the indoor unit of the wall-mounted air conditioner is increased more quickly.
Further, in the wall-mounted air conditioner indoor unit of the invention, the flow guide part is formed on the inner side of the bottom wall of the shell so as to define a flow passage communicated with the strip-shaped breeze hole with the bottom wall of the shell. The flow guide part comprises a channel baffle and a connecting plate. The channel baffle plate and the bottom wall of the shell jointly define a flow passage, and can guide air flow to the strip-shaped micro air holes. The connecting plate extends backward from the top end of the channel enclosure plate to be connected with the front end of the rear wall of the air channel, so that the connecting plate is equivalent to an extension section of the rear wall of the air channel, the connection transition of the rear wall of the air channel and the connecting plate is more natural and smooth, and extra on-way resistance cannot be brought to air flow. And the air supply flow passes through the air duct rear wall and the connecting plate and then is bent downwards to enter the air passage channel, so that the bottom wall of the shell, the rear wall of the channel baffle plate and the air duct rear wall form a step surface, and when the wall-mounted air conditioner indoor unit operates for refrigeration, the step surface structure can effectively prevent condensation at the position of the strip-shaped micro air duct.

Detailed Description
A wall-mounted type air conditioning indoor unit according to an embodiment of the present invention will be described with reference to fig. 1 to 6. Where the orientations or positional relationships indicated by the terms "front," "back," "upper," "lower," "top," "bottom," "inner," "outer," "lateral," and the like are based on the orientations or positional relationships shown in the drawings, the description is for convenience only and to simplify the description, and no indication or suggestion is made that the device or element so indicated must have a particular orientation, be constructed and operated in a particular orientation, and is therefore not to 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; fig. 2 is an enlarged view of fig. 1 at a.
As shown in fig. 1 and 2, the wall-mounted air conditioning indoor unit according to the embodiment of the present invention includes a casing 10, an air outlet 12 is formed at a bottom of a front side of the casing 10, and at least one elongated micro air vent 13 extending in a transverse direction (the transverse direction is already indicated in the relevant drawings) of the casing 10 is formed in a bottom wall 101 of the casing 10. The elongated breeze holes 13 are used to achieve the breeze effect and have a narrow width, for example, the width may be less than 30 mm. The air outlet 12 and the elongated micro-air holes 13 are used for discharging the supply air flow in the housing 10. The supply air flow is usually heat exchange air which exchanges heat with the heat exchanger, and of course, the supply air flow can also be fresh air flow. The elongated louvers 13 may be located in a front region of the bottom wall 101 of the housing so as to be adjacent to the air outlet 12.
Specifically, a plurality of air guide vanes 80 are disposed in each of the elongated micro air holes 13 at intervals along the length direction thereof. The plurality of air guide blades 80 are configured to adjust the air outlet direction of the elongated micro air holes 13 when driven to rotate synchronously.
In the wall-mounted air conditioner indoor unit provided by the embodiment of the invention, only the air outlet 12 is formed, and at least one strip-shaped breeze hole 13 is formed in the bottom wall 101 of the shell 10, so that a non-wind-sensing air supply mode is realized, and comfortable air supply is realized.
Specifically, when the wall-mounted air conditioning indoor unit is turned on and the air outlet 12 is opened, a main portion of the supply airflow inside the casing 10 is blown from the air outlet 12 to the indoor, thereby cooling/heating the indoor environment. And the other part of the main part of the blowing air flow is blown into the room through the strip-shaped micro air holes 13. Because the width of the strip-shaped micro air holes 13 is narrower, the air flow is softer and has no wind sense, discomfort caused by that cold air or hot air strongly blows the human body is avoided, and comfortable air supply of the air conditioner is realized. When the air outlet is closed (for example, closed by an external air deflector), all the air supply flow is forced to flow to the strip-shaped breeze holes 13, so that the strip-shaped breeze holes 13 supply air with large air volume, and the effect of completely supplying air without wind sense is realized.
In addition, in the embodiment of the present invention, the wall-mounted air conditioning indoor unit not only can realize micro-pore air supply, but also can adjust the air outlet direction of the strip-shaped micro-air holes 13 by using the plurality of air guide blades 80. For example, the air outlet direction of the strip-shaped micro air holes 13 can be kept away from the human body by controlling the air guide angle of the plurality of air guide blades, so that cold air/hot air can be completely prevented from blowing people. In addition, the plurality of air guide blades 80 can adjust the air outlet direction of the strip-shaped breeze holes 13 and also can adjust the air outlet quantity of the strip-shaped breeze holes 13. Finally, the plurality of air guide blades 80 also play a role in scattering air flow supplied by the strip-shaped micro air holes 13, so that the softness of the air flow is enhanced. In a word, the existing micropore air outlet scheme focuses more on the micropores, and the air supply angle, the air quantity and the softness of the micropores with the air guide blades of 80 degrees are arranged to control, so that the micropore air outlet control is further refined.
In the wall-mounted air conditioner indoor unit provided by the embodiment of the invention, the long-strip-shaped micro air holes 13 are positioned on the bottom wall 101 of the shell 10, so that air can be supplied vertically downwards, and the defect that a traditional air outlet is not beneficial to supplying air vertically downwards is overcome. In the heating mode, the air is vertically and downwards supplied by the strip-shaped micro air holes 13, so that the temperature of the area right below the indoor unit of the wall-mounted air conditioner is increased more quickly.
In some embodiments, as shown in fig. 1, the wall-mounted air conditioning indoor unit may further include an outer air guide plate 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 can be seen that the rotation axis of the outer wind guide plate 50 is parallel to the lateral direction of the case 10.
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 completely supplies air without wind sense through the strip-shaped micro air 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.
In some embodiments, as shown in fig. 2, each air guide blade 80 includes a pivot 82 and a plate 81. The pivot 82 extends in the width direction (y-axis direction) of the elongated louver 13, and is pivotably attached to both side walls in the width direction of the elongated louver 13. The plate 81 is connected to the pivot 82 to guide wind. The plate 81 and the pivot 82 are preferably integrally formed as a single piece. Two lateral walls in the width direction of the elongated louvers 13 are opened to mount the pivot 82.
The number of the elongated micro-wind holes 13 is plural, and the plural elongated micro-wind holes 13 are arranged at intervals along the width direction of the elongated micro-wind holes 13, for example, two elongated micro-wind holes 13 are provided as shown in fig. 2. Moreover, the air guide blades 80 of the strip-shaped micro-wind holes 13 are arranged in a matrix form, and the pivot shafts 82 of the air guide blades 80 at the same position in the length direction (x-axis direction) of the strip-shaped micro-wind holes 13 are fixedly connected. Alternatively, the guide blades 80 located at the same position in the longitudinal direction (x-axis direction) of the elongated louvers 13 share the same pivot axis. In this way, the air guide vanes 80 of all the elongated micro-air holes 13 can share one driving mechanism, and the structure is further simplified.
In the embodiment in which a plurality of elongated louvers 13 are provided, the width of each elongated louver 13 may be different so that more louver patterns can be obtained by controlling the opening and closing of each elongated louver 13. For example, for two elongated louvers 13, one wide and one narrow, the wider elongated louvers 13 may be closed by the air guiding blade 80, so that the narrower elongated louvers 13 can supply air independently. Or, the narrow strip-shaped breeze holes 13 are closed, so that the wide strip-shaped breeze holes 13 independently supply air. Or, the narrow and wide strip-shaped breeze holes 13 are opened to supply air at the same time.
In some embodiments, as shown in fig. 2, the plate 81 of the wind guiding blade 80 may include a main body 811. Main body 811 is located above pivot 82 (i.e., on the side closer to the inside of the housing) to constitute the main body of plate 81, and is mainly used for guiding air. The main body 811 extends into the casing 10 to adjust the flow direction of the supply air flow before it enters the elongated louvers 13, and to prevent the supply air flow from being outside the casing and affecting the appearance of the casing.
As shown in fig. 2, the wall-mounted type air conditioning indoor unit further includes a link 90 and a motor 60. The link 90 extends along the length direction of the elongated louvers 13 and is connected to a tail portion 812 of each plate 81 located below the pivot 82, and the link 90 has a rack 91 formed thereon. The motor 60 is mounted on the bottom wall 101 of the housing, and the gear 61 engaged with the rack 91 is mounted on the motor 60. When the motor 60 rotates forward or backward, the gear 61 drives the connecting rod 90 (toward the x axis positive direction or negative direction) to translate through the rack 91, and the connecting rod 90 drives the guide vanes 80 to rotate synchronously. The connecting portion of the tail portion 812 of the plate 81 and the connecting rod 90 has a thinner thickness or a lower hardness than the remaining portion of the tail portion 812, so that the plate 81 rotates integrally about the pivot 82 when the connecting rod 90 translates.
Fig. 3 is a schematic structural view of the wall-mounted air conditioning indoor unit of fig. 1 with an external air deflector hidden; fig. 4 is an enlarged cross-sectional view of the wall-mounted air conditioning indoor unit shown in fig. 1; fig. 5 is a schematic view showing a structure of a casing in the wall-mounted type air conditioning indoor unit of fig. 1; fig. 6 is an enlarged view of fig. 5 at B.
As shown in fig. 3 to 6, the wall-mounted air conditioning indoor unit further includes a guide portion 70 and an air duct 20. The flow guide part 70 is located on the inner side of the bottom wall 101 of the housing 10 and defines a flow passage 701 communicating with the elongated micro-wind hole 13 together with the bottom wall 101 of the housing 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 elongated micro-air 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 with the bottom wall 101 the aforementioned overflow channels 701. The passage enclosure 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 connected to the bottom wall 101 of the housing. 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 channel baffle 71 not only defines the flow channel 701 together with the bottom wall 101 of the housing 10, but also guides the flow of the supply air to the elongated micro-air 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, the step surface structure can effectively prevent condensation from occurring at the long-strip-shaped breeze hole 13, and condensation water is prevented from dripping out through the long-strip-shaped breeze hole 13.
In some embodiments, as shown in fig. 5-6, 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.
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.
