The invention provides a wall-mounted indoor unit and an air conditioner comprising the same, wherein the wall-mounted indoor unit can realize multi-surface windless air outlet so as to improve the comfort level of a user using the wall-mounted indoor unit.

Referring to fig. 1 and 2, in a first embodiment of the wall-mounted indoor unit of the present invention, the wall-mounted indoor unit includes a housing and a wind deflector 300. The shell comprises a shell body 100 and a bottom shell 200 detachably arranged at the lower end of the shell body 100, an air outlet channel 610 is formed in the shell body 100, a cavity communicated with the air outlet channel 610 is formed in the inner side of the bottom shell 200, the bottom shell 200 comprises a front air dispersing plate 210 and side air dispersing plates 220 arranged on two sides of the front air dispersing plate 210, the front air dispersing plate 210 is provided with an air outlet communicated with the air outlet channel 610, and a plurality of first air dispersing holes communicated with the cavity are formed in the side air dispersing plates 220; the wind deflector 300 is rotatably installed at the air outlet for opening or closing the air outlet.

Specifically, the casing body 100 includes a top frame 120 mounted on the top end of the top frame 110, an air inlet 121 is formed in the top frame 120, a volute 600 for forming an air outlet channel 610 is formed at the bottom of the top frame 110, the wind wheel 500 of the wall-mounted indoor unit is disposed at the inlet end of the air outlet channel 610, and the heat exchanger 400 of the wall-mounted indoor unit is disposed above the wind wheel 500 in a semi-surrounding manner.

The inner side of the bottom case 200 is formed with a cavity communicating with the air outlet channel 610, the front air dispersing plate 210 of the bottom case 200 is a panel facing the user in the working state of the wall-mounted indoor unit, and the air dispersing plates 220 on two sides of the bottom case 200 are respectively positioned on the left side and the right side of the front air dispersing plate. The plurality of first air-diffusing holes on the side air-diffusing plates 220 are all communicated with the cavity, so that part of the air flow blown out through the air-out channel 610 can flow into the cavity and be blown out through the first air-diffusing holes on the side air-diffusing plates 220. Obviously, in order to make the air outlets on two sides of the bottom case 200 more uniform, the first air-diffusing holes should be more uniformly distributed on the side air-diffusing plate 220. The forming manner of the cavity is not particularly limited, and for example, the cavity may be formed by enclosing the bottom plate of the face frame 110 with the bottom case 200, or the coaming structure 240 (see fig. 6) may be disposed on the inner side of the bottom case 200, so that the cavity is formed by enclosing the coaming structure 240 with the bottom case 200, which will be described in detail later.

When the wall-mounted indoor unit works, the wind wheel 500 drives the air inlet flow to enter the shell body 100 from the air inlet 121, after the air inlet flow exchanges heat through the heat exchanger 400, the wind wheel 500 drives the air inlet flow after the heat exchange to blow to the air outlet channel 610 to form air outlet flow, and the air outlet flow forms a plurality of small airflows at the tail end of the air outlet channel 610, wherein a first airflow (shown as I in the figure) blows out forwards through the air outlet, a second airflow (shown as II in the figure) blows out laterally through a first air dispersing hole on one side air dispersing plate 220, and a third airflow (shown as III in the figure) blows out laterally through a first air dispersing hole on the other side air dispersing plate 220, and obviously, the second airflow and the second airflow are scattered by the first air dispersing hole to become softer, and the wind speed is reduced, so that no wind sensation is achieved.

Consider in order to be convenient for clean drain pan 200, with drain pan 200 demountable installation in the lower extreme of shell body 100 to the user washs with drain pan 200 whole dismantlement, avoids first louvre laying dust on the drain pan to influence air-out volume or air-out quality, convenient and fast. As for the detachable mounting manner of the bottom case 200, for example, the bottom case 200 and the case body 100 may be connected by any one or more combination of a snap structure, a screw structure, or a latch structure.

According to the wall-mounted indoor unit, the bottom shell 200 is detachably arranged at the lower end of the shell body 100, the cavity communicated with the air outlet channel 610 in the shell body 100 is formed at the inner side of the bottom shell 200, the air outlet communicated with the air outlet channel 610 is formed in the front air dispersing plate 210, the plurality of first air dispersing holes communicated with the cavity are formed in the side air dispersing plate 220 in a penetrating mode, so that when the wall-mounted indoor unit works, a plurality of small air flows are formed at the tail end of the air outlet channel 610 by the air outlet, wherein the first air flows through the air outlet, the second air flows through the first air dispersing holes in the air dispersing plate 220 on one side, and the third air flows through the first air dispersing holes in the air dispersing plate 220 on the other side, and therefore multi-surface air outlet of the wall-mounted indoor unit is achieved, the air speed of the air outlet is reduced, the air outlet is soft, and the air outlet is prevented from being intensively blown to users. Furthermore, the bottom shell 200 is detachably mounted at the lower end of the shell body 100, so that a user can detach the whole bottom shell 200 for cleaning, and the cleaning is convenient and quick.

Referring to fig. 3 and fig. 4, in order to increase the non-wind-sensing air-out effect of the wall-mounted indoor unit, in the second embodiment of the present invention, on the basis of the first embodiment, the front air-diffusing plate 210 is perforated with a plurality of second air-diffusing holes communicated with the cavity, so that the wall-mounted indoor unit can also realize the non-wind-sensing air-out through the front air-diffusing plate 210.

Specifically, the air outlet is disposed at the lower side of the front air diffuser 210, a part of the second air diffusing holes are disposed at the upper side of the front air diffuser 210, and another part of the second air diffusing holes are disposed at the periphery of the air outlet, so that the front side of the bottom shell 200 has no wind sensing and is uniform. By disassembling the bottom shell 200, the first air dispersing holes and the second air dispersing holes on the bottom shell 200 can be cleaned, so that the influence of dust accumulation on the refrigerating/heating effect is avoided. When the wall-mounted indoor unit works, by opening or closing the wind screen 300, the following two air-out modes can be realized:

In this mode, as shown in fig. 3, the wind deflector 300 opens the air outlet, and the air outlet flows through the end of the air outlet channel 610 into the cavity, and the air outlet is divided into a plurality of small air flows in the cavity, wherein the first air flow is blown out through the air outlet; the second air flow is blown out laterally through the first air dispersing holes on the air dispersing plate 220 on one side; the third air is blown out laterally through the first air-diffusing holes on the air-diffusing plate 220 on the other side; the fourth stream is blown forward through the second air bleed holes in the front air bleed plate 210. That is, the air-out airflow is divided into a plurality of airflows at the end of the air-out channel 610, and the airflows are diffused and blown out from the lower end of the shell, so that the wall-mounted indoor unit has a larger air-out range without wind sense. The air flow of the first air flow is obviously larger than that of other air flows, the air speed is high, and the air outlet mode is suitable for the initial stage of refrigeration/heating and can rapidly disperse air indoors.

Further, since the wall-mounted indoor unit distributes the air through the front air diffuser 210 and the side air diffuser 220, the air flow of the first air flow is smaller than that of the conventional concentrated air flow, so that the first air flow is still blown forward directly and is not concentrated to the user.

Referring to fig. 4, in this mode, the wind deflector 300 closes the air outlet, the air outlet flows through the end of the air outlet channel 610 into the cavity, and multiple small airflows are separated in the cavity, wherein the first airflow is blown out through the first air outlet hole on one side of the air deflector 220, the second airflow is blown out through the first air outlet hole on the other side of the air deflector 220, and the third airflow is blown out forwards through the second air outlet hole on the air deflector, so as to realize that the wall-mounted indoor unit has no air outlet completely. The mode is suitable for uniformly and softly dispersing air indoors after the wall-mounted indoor machine works for a period of time.

In the third embodiment of the present invention, the difference from the second embodiment is that the wind guard 300 is provided with the fourth air-diffusing hole, so that the air outlet can be enabled to emit air without sense of wind. When the wall-mounted indoor unit works, the wind shield 300 is opened, and the air outlet flows through the tail end of the air outlet channel 610 and enters the cavity, and a plurality of small air flows are separated in the cavity, wherein the first air flow flows through the front wind dispersing plate 210 and the wind shield 300 to be blown out forwards; the second air flow is blown out laterally through the first air dispersing holes on the air dispersing plate 220 on one side; the third air flows through the first air-dispersing holes on the air-dispersing plate 220 at the other side to blow out laterally, so that three-face air-out of the wall-mounted indoor unit is realized, at this time, the air-out face of the bottom shell 200 is maximum, and the air-out quantity and the air-out range are both maximum. When the wind shield 300 is closed, the air outlet is exposed, and the wall-mounted indoor unit can realize the three-side air outlet effect, and can also discharge part of air outlet air flow from the air outlet to the indoor so as to realize rapid air supply.

It should be noted that the shapes of the first air vent, the second air vent, the third air vent, and the fourth air vent are not limited, and each air vent may be a circular hole, a square hole, a polygonal hole, or a special-shaped hole. Taking the first air vent as an example, the first air vent is provided as a round hole, and the structure is simple and is easy to manufacture and form; or the first air dispersing holes are petal-shaped holes, so that the effect of decorating the appearance of the shell can be achieved besides the effect of air outlet without wind sense.

Referring to fig. 5 and 6, according to any of the above embodiments, the cavity includes a first sub-cavity 1a communicating with the first air vent, and a second sub-cavity 2a communicating with the second air vent; the first sub-cavity 1a and the second sub-cavity 2a are respectively communicated with the air outlet channel 610, or the first sub-cavity 1a and the second sub-cavity 2a are mutually communicated, and one of the first sub-cavity 1a and the second sub-cavity 2a is communicated with the air outlet channel 610.

Specifically, each side air diffuser 220 is correspondingly provided with a first sub-cavity 1a, and the first sub-cavity may cover the whole inner side surface of the side air diffuser, or the first sub-cavity may cover only part of the inner side surface of the side air diffuser.

Referring to fig. 6, in this embodiment, in order to prevent the air flow from the side air diffuser 220 from blowing toward the wall, the first air diffuser holes are disposed at the front end of the side air diffuser 220, and a plurality of blind holes are disposed at the rear end of the side air diffuser 220. Specifically, the first sub-cavity 1a only extends to the front end of the side air diffuser 220, and the aperture size of the blind hole is equal to that of the first air diffuser, so that the side air diffuser 220 has a better overall appearance effect, and the surface of the side air diffuser 220 has a certain roughness, so that slipping can be avoided when a user carries the wall-mounted indoor unit or disassembles the bottom shell.

Referring to fig. 6 again, in this embodiment, in order to form a relatively complete cavity on the inner side of the bottom case 200, a coaming structure 240 is disposed on the inner side of the bottom case 200, and the coaming structure 240 includes a front coaming opposite to the front air diffuser 210 and a side coaming opposite to the side air diffuser 220, where the side coaming and the side air diffuser 220 enclose a first sub-cavity 1a, and the front coaming encloses a second sub-cavity 2a with the upper side of the front air diffuser 210.

Specifically, the coaming structure 240 and the bottom case 200 may be connected by bonding, screwing, or fastening, or the coaming structure 240 and the bottom case 200 may be integrally formed, which is not particularly limited herein. To facilitate cleaning of the bottom chassis 200, the coaming structure 240 is preferably connected to the bottom chassis 200 by a snap-fit connection, so that the coaming structure 240 is detached from the bottom chassis 200 after the bottom chassis 200 is detached as a whole, so as to avoid interference of the coaming structure 240 with cleaning of the bottom chassis 200.

With continued reference to fig. 6, further, the front air diffuser 210 is formed separately or integrally with the two side air diffusers 220. If the front air diffuser 210 and the two side air diffusers 220 are separately arranged, the front air diffuser 210 and the two side air diffusers 220 are separately detached after the bottom shell 200 is integrally detached, so that the front air diffuser 210 and the two side air diffusers 220 are separately cleaned. If the front air diffuser 210 and the air diffuser 220 are integrally formed, the bottom case 200 is ensured to be compact, so that the bottom case 200 has a better overall effect.

There are various ways in which the first sub-cavity 1a and the second sub-cavity 2a communicate with the air outlet channel 610, and the following three communication ways are exemplified here:

communication mode one: the two first sub-cavities 1a and the second sub-cavities 2a are respectively communicated with the air outlet channel 610, so that the air outlet air flow can be directly split into the first sub-cavities 1a and the second sub-cavities 2a at the tail end of the air outlet channel 610 and correspondingly blown into a room from the first air dispersing holes and the second air dispersing holes, the split and blown-out path of the air outlet air flow is shorter, and therefore, the rapid cooling/heating can be realized on the basis of realizing the air outlet without wind sensation.

And a second communication mode: the two first sub-cavities 1a are all communicated with the second sub-cavity 2a, and the two first sub-cavities 1a are communicated with the air outlet channel 610, so that the air outlet air flow is split into the two first sub-cavities 1a, part of the air flow in the two first sub-cavities 1a flows through the first air dispersing holes and is blown out, and the other part of the air flow in the two first sub-cavities 1a flows into the second sub-cavity 2a from the two ends of the second sub-cavity 2a respectively and is blown out through the second air dispersing holes. In this arrangement, no air gap is formed between the second sub-cavity 2a and the air outlet channel 610, so as to prevent external dust from falling into the air outlet channel 610 from the air gap.

And a communication mode III: the two first sub-cavities 1a are all communicated with the second sub-cavity 2a, and the second sub-cavity 2a is communicated with the air outlet channel 610, so that the air outlet air flow is split into the second sub-cavity 2a, part of the air flow in the second sub-cavity 2a is blown out through the second air dispersing holes, and the other part of the air flow in the second sub-cavity 2a flows into the two first sub-cavities 1a from the two ends of the second sub-cavity 2a respectively and is blown out through the first air dispersing holes. Because the volume of the second sub-cavity 2a is larger than that of the first sub-cavity 1a, more air-out air flows are collected through the second sub-cavity 2a, so that the air-out air flows spread to the first sub-cavities 1a at two sides of the second sub-cavity, and the air-out air quantity without wind sensation is increased.

The above three communication modes can realize the diversion effect on the air outlet air flow, and the corresponding adjustment is specifically performed according to the actual air outlet requirement and the cavity molding difficulty, without limitation.

Referring to fig. 7 and 8, in this embodiment, in order to selectively control the air outlet of any one side or multiple sides of the wall-mounted indoor unit, the casing is provided with an air outlet which is communicated with the first sub-cavity 1a and the air outlet channel 610, or is communicated with the second sub-cavity 2a and the air outlet channel 610, or is communicated with the first sub-cavity 1a and the second sub-cavity 2a, and an air door is movably installed at the air outlet and is used for opening or closing the air outlet, so that the on-off state of the cavity can be controlled by controlling the on-off state of the air door, and then the air outlet of any one side or multiple sides of the wall-mounted indoor unit can be selectively controlled. For example, when all the air doors are closed, the air outlet air flow is blown into the room only from the air outlet, so that a conventional air outlet mode is realized; when all the air doors are opened, the air outlet air flow is split at the tail end of the air outlet channel 610 and is blown out from the first air outlet hole and the second air outlet hole, so that a three-face (front side and left and right sides) air outlet mode without wind sense is realized.

Referring to fig. 9 and 10, for convenience of explanation, an air port for communicating the first sub-cavity 1a with the air outlet channel 610 is defined as a first air port 1b (refer to fig. 8), and an air door corresponding to the first air port 1b is defined as a first air door; the air-passing opening for communicating the second sub-cavity 2a with the air-out passage 610 is defined as a second air-passing opening, and the air door corresponding to the second air-passing opening is defined as a second air door 2b.

If the first sub-cavity 1a, the second sub-cavity 2a and the air outlet channel 610 adopt the first communication mode, a first air passing opening 1b needs to be arranged between the communication of each first sub-cavity 1a and the air outlet channel 610, a first air door is movably installed at the first air passing opening 1b, a second air passing opening is arranged between the second sub-cavity 2a and the air outlet channel 610, and a second air door 2b is movably installed at the second air passing opening. When only the first air door is opened, the wall-mounted indoor unit realizes three-side air outlet through the wind guard 300 and the air dispersing plates 220 on two sides; when only the second damper 2b is opened, the wall-mounted indoor unit only achieves front air outlet through the wind deflector 300 and the front air diffuser 210, and both sides of the wall-mounted indoor unit do not air outlet.

If the first sub-cavity 1a, the second sub-cavity 2a and the air outlet channel 610 adopt the second communication method, only the first air gap 1b is required to be arranged between each first sub-cavity 1a and the air outlet channel 610, and the first air door is movably installed at the first air gap 1 b. When the first air door is closed, the wall-mounted indoor unit simply diffuses air forwards through the wind shield 300; when the first air door is opened, the wall-mounted indoor unit realizes three-side air outlet through the wind guard 300, the front air dispersing plate 210 and the air dispersing plates 220 at two sides, and the air outlet range is large.

If the first sub-cavity 1a, the second sub-cavity 2a and the air outlet channel 610 adopt the third communication mode, only a second air port needs to be arranged between the second sub-cavity 2a and the air outlet channel 610, and a second air door 2b is movably installed at the second air port. When the second damper 2b is closed, the wall-mounted indoor unit diffuses the wind forward only through the wind deflector 300; when the second damper 2b is opened, the wall-mounted indoor unit can realize three-side air dispersion through the wind guard 300, the front air dispersion plate 210 and the two side air dispersion plates 220.

With continued reference to fig. 9 and 10, in this embodiment, the damper is slidably connected to the bottom case 200, so that the damper can slidingly open or close the air gap; or the damper is pivoted to the bottom case 200 so that the damper rotates to open or close the air outlet.

The first damper and the second damper 2 may be both mounted in a sliding connection or in a pivoted connection, and the second damper 2b is described in detail herein as an example, and other dampers may be provided with reference to the embodiment of the second damper 2 b. If the second air door 2b is slidably connected to the bottom case 200, a slider (not shown) may be disposed at two ends of the second air door 2b, a chute (not shown) corresponding to the slider may be disposed on the face frame 110, and the second air door 2b may be driven to slide in the chute by a driving device (not shown) to open or close the second air outlet. In this movable mounting manner, when the bottom case 200 needs to be disassembled and washed, the second air door 2b can be accommodated on the face frame 110, and the bottom case 200 can be disassembled, so that damage to the second air door 2b in the process of cleaning the bottom case 200 is avoided. Of course, the sliding groove can also be arranged on the bottom shell 200 or the coaming structure 240 thereof

In addition, if the second damper 2b is pivoted to the bottom case 200, pivot shafts (not shown) may be disposed at two ends of the second damper 2b, and a shaft hole (not shown) corresponding to the pivot shafts is disposed on the bottom case 200, and the damper is driven to rotate by a driving device to open or close the air passing opening. The movable mounting mode has a simple structure and is easy to manufacture.

In other embodiments, to enhance the effect of the wall-mounted indoor unit without wind, the casing is provided with an air port that communicates with the first sub-cavity 1a and the air outlet channel 610, or communicates with the second sub-cavity 2a and the air outlet channel 610, or communicates with the first sub-cavity 1a and the second sub-cavity 2a, and the air port is provided with an air passing grid (not shown). Through setting up the air-out air current wind speed that crosses the air grid can be made to pass through the air-out air current wind speed that crosses the air grid reduces, and when the air current after this reduces wind speed passed through first louvre or second louvre, air-out air current wind speed further reduces, and its no wind sense effect is better.

Referring to fig. 11, in this embodiment, in order to increase the air outlet surface of the bottom case 200, the front air-diffusing plate 210 and the side air-diffusing plate 220 are connected by adopting an arc-shaped air-diffusing portion 230 in a smooth transition manner, and the arc-shaped air-diffusing portion 230 is provided with a third air-diffusing hole. The arc-shaped air dispersing part 230 may be a part of the front air dispersing plate 210, or a part of the side air dispersing plate 220, or the arc-shaped air dispersing part 230 may be a single structure independent from the front air dispersing plate 210 and the side air dispersing plate 220. The arc-shaped air dispersing part 230 is integrally formed with the front air dispersing plate 210 and the side air dispersing plate 220.

Because the arc-shaped air dispersing part 230 is arranged in an outwards convex arc shape, the third air dispersing holes in the arc-shaped air dispersing part 230 are arranged in a divergent shape on the arc-shaped air dispersing part 230, and therefore the air outlet surface of the bottom shell 200 is effectively enlarged by the arc-shaped air dispersing part 230.

Obviously, since the two side air dispersing plates 220 and the two arc-shaped air dispersing parts 230 are equally arranged at two sides of the bottom shell 200, the air outlet range or the air outlet direction of the wall-mounted indoor unit can be correspondingly adjusted by reasonably setting the through direction of the first air dispersing holes and the third air dispersing holes.

With continued reference to fig. 11, one of the penetrating manners of the first air vent and the third air vent is as follows: the penetrating direction of the first air vent is perpendicular to the plate surface of the side air vent 220, and the penetrating direction of the third air vent is inclined downward, so as to enlarge the range of the wall-mounted indoor unit without wind.

Specifically, the first air vent is perpendicular to the plate surface of the side air vent 220 and penetrates the side air vent 220, the third air vent penetrates the air outlet surface of the arc-shaped air vent 230 from the windward side of the arc-shaped air vent, and the penetrating direction of the third air vent is inclined downward. With this arrangement, the wall-mounted indoor unit has a wider range of air-out without wind sense.

Referring to fig. 12, the second through manner of the first air vent and the third air vent is: the through direction of the first air dispersing holes and the through direction of the third air dispersing holes are inclined forwards, so that the wall-mounted indoor unit is integrally and forwards supplied with air, and air-out airflow is prevented from blowing to a wall body.

Specifically, the first air vent penetrates from the windward side of the side air vent 220 to the air outlet side thereof, and the penetrating direction of the first air vent is inclined forward, and the penetrating direction of the third air vent is parallel to the penetrating direction of the first air vent, so that the air outlet flow of the wall-mounted indoor unit is blown forward as a whole, and the air outlet flow is prevented from blowing to the wall. The air outlet flow passing through the first air dispersing holes and the third air dispersing holes is softer and has smaller speed, so that a user can not feel the wind speed, and discomfort of the user can be avoided.

Referring to fig. 12, a third through manner of the first air vent and the third air vent is as follows: the through direction of the first air dispersing hole and the through direction of the third air dispersing hole are arranged at an acute angle, so that the air outlet flow of the wall-mounted indoor unit is dispersed to the indoor in a divergent mode.

Specifically, the first air vent is formed from the windward side of the side air vent 220 to the air outlet side thereof, and the through direction of the first air vent is inclined forward, the windward side of the third air vent from the arc-shaped air vent 230 is formed from the air outlet side thereof, and the through direction of the third air vent is also inclined forward, and an acute angle is formed between the through direction of the first air vent and the through direction of the third air vent, so that the air flow is diffused indoors in a divergent manner after being blown out from the first air vent and the third air vent respectively.

As for the through direction of the second air vent, for example, the second air vent may be formed through from the windward side of the front air plate 210 to the air outlet side thereof, and the through direction of the second air vent may be inclined upward, so as to expand the range of the wall-mounted indoor unit without wind. However, in order to avoid the upward backflow of the air-out flow, it is preferable that the penetrating direction of the second air-diffusing hole be inclined downward.

In this embodiment, in order to facilitate guiding a part of the air-out airflow into the cavity and guiding the air-out airflow into the first air-dispersing hole, the second air-dispersing hole and the third air-dispersing hole, the inner ends of the first air-dispersing hole, the second air-dispersing hole and the third air-dispersing hole are all in an arc-shaped tapered shape from inside to outside, so that the air-out airflow is guided into the first air-dispersing hole, the second air-dispersing hole and the third air-dispersing hole correspondingly.

Further, in order to be convenient for follow the air-out air current first louvre, second louvre, the outside derivation of third louvre, the outer end of first louvre, second louvre, third louvre all is the setting of arc flaring form from inside to outside. The effect of the arc flaring is specifically described by taking a first air vent as an example: the outer end of the first air dispersing hole is provided with an arc-shaped flaring which reduces the resistance of airflow flow on one hand and is beneficial to rapidly dispersing the airflow passing through the first air dispersing hole; on the other hand, part of the airflow diffuses to the air outlet surface of the side air dispersing plate 220 along the arc-shaped flaring so as to balance the temperature difference between the windward surface and the air outlet surface of the side air dispersing plate 220 and avoid the generation of condensed water on the air outlet surface of the side air dispersing plate 220.

The foregoing description is only of the preferred embodiments of the present invention and is not intended to limit the scope of the invention, and all equivalent structural changes made by the description of the present invention and the accompanying drawings or direct/indirect application in other related technical fields are included in the scope of the invention.
