the flow guide piece is of a hollow structure, one side of the flow guide piece facing the first air supply outlet is provided with a spray hole, and the flow guide piece is configured to prepare water mist; and is
In the flowing process of the air supply flow, a negative pressure environment is formed at the spray hole to promote the water mist to be mixed into the air supply flow and to be blown out of the first air supply opening together.
Optionally, an ultrasonic oscillation component is arranged in the flow guide piece, so as to atomize the liquid water inside the flow guide piece.
Optionally, the flow guide member is connected with a water injection pipe extending to the outside of the casing so as to inject liquid water into the flow guide member through the water injection pipe.
Optionally, the first air supply outlet is opened at the front part of the casing.
Optionally, the casing is configured to make the rising angle of the airflow at the bottom section of the air outlet gap greater than the declining angle of the airflow at the top section of the air outlet gap, so that the airflow at the bottom section of the air outlet gap drives the airflows at the rest sections to flow upward together.
Optionally, the outlet of the air duct adjacent to the first air supply opening is in a strip shape, and the length direction of the outlet is parallel to the transverse direction of the machine shell; and the water conservancy diversion spare is for the shaft-like that extends along the transverse direction of casing to all injecing the air-out clearance with the upside in wind channel and the inner wall of downside.

In the wall-mounted air conditioner indoor unit, the inner wall of the air duct close to the first air supply opening is gradually reduced, so that the flow cross section of the air duct is gradually reduced along the airflow direction. An air outlet gap is defined between the flow guide piece inside the air duct and the inner wall of the air duct. When the air supply airflow blows to the first air supply outlet, the air supply airflow is guided by the flow guide piece to flow to the inner wall of the air duct and enter the air outlet gap. Because the overflowing cross section of the air outlet gap is smaller, the air outlet speed is higher. The high-speed air supply airflow is gradually converged towards the center direction of the airflow in the outward flowing process under the guidance of the gradually-reduced inner wall of the air duct to form a convergence effect, so that the wind power is stronger, the air supply distance is longer, and the requirements of the wall-mounted air conditioner indoor unit on long-distance air supply and strong air supply are met.
And the flow guide piece is of a hollow structure and is provided with a spraying hole, and the flow guide piece can be used for preparing water mist. When the high-speed flowing air supply flow flows to the first air supply outlet, a negative pressure area is generated around the spray hole, the water mist is sucked into the air supply flow, and then the air supply flow is wrapped with the water mist and blown to the indoor. Therefore, the mixing degree of the water mist and the air supply flow is very high, the water mist and the air supply flow can be conveyed to all places in a room along with the air supply flow, and the diffusion range is wider. And need not to establish special fan or other supply-air outlets in addition, the structure is very simple ingenious.
Furthermore, the wall-mounted air conditioner indoor unit provided by the invention designs the shape of the air duct, so that the rising angle of the airflow at the bottom section of the air outlet gap is larger than the declining angle of the airflow at the top section, the rising angle of the rising part of the airflow is larger than the declining angle of the sinking part, and the airflow mixed by a plurality of airflows is integrally raised and flows. In the refrigeration mode, the rising and flowing cold air can fully avoid the human body and scatter downwards after reaching the highest point, so that the shower type refrigeration experience is realized. Moreover, the air flow is blown upwards to be beneficial to improving the air supply distance.
Furthermore, the wall-mounted air conditioner indoor unit of the invention is provided with a second air supply outlet facing downwards at the bottom of the casing, so as to supply air to the lower part of the wall-mounted air conditioner indoor unit. The downward air supply in the heating mode is more favorable for accelerating the temperature rising speed of the lower-layer space of the house, so that the human body can feel the heating effect more quickly.
Furthermore, the wall-mounted air conditioner indoor unit of the invention enables the top of the shell to be provided with the first air inlet and the front part to be provided with the second air inlet, so that the air inlet volume is increased, the heat exchange efficiency of the front section of the heat exchanger is improved, and the overall energy efficiency of the air conditioner is improved.

The embodiment of the invention provides a wall-mounted air conditioner indoor unit, which is an indoor part of a split wall-mounted air conditioner and is used for adjusting indoor air, such as refrigeration/heating, dehumidification, fresh air introduction and the like.
Fig. 1 is a schematic structural view of a wall-mounted type air conditioning indoor unit according to an embodiment of the present invention; fig. 2 is a schematic side view of the wall-mounted air conditioning indoor unit shown in fig. 1; fig. 3 is a schematic view of the wall-mounted air conditioning indoor unit of fig. 1 with the movable panel 20 in a closed position; FIG. 4 is a schematic view of the construction of the baffle 30; fig. 5 is an enlarged sectional view of a wall-mounted air conditioning indoor unit according to an embodiment of the present invention in a polymeric blowing mode. Fig. 5 illustrates only the air blowing principle of the wall-mounted air conditioning indoor unit, and the partial structure is not completely consistent with fig. 1 to 4.
As shown in fig. 1 to 5, a wall-mounted type air conditioning indoor unit according to an embodiment of the present invention may generally include a cabinet 10 and a guide 30.
The casing 10 defines a first blowing port 11 and a duct 15 connected to the first blowing port 11. The casing 10 of the present embodiment 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 an air outlet channel. The first air blowing port 11 is used for blowing an air flow in the casing 10 into a room to condition indoor air. The air supply flow can be cold air produced by the wall-mounted air conditioner indoor unit in a refrigeration mode, hot air produced by the wall-mounted air conditioner indoor unit in a heating mode or other air flows. The number of the first blowing ports 11 may be one or more. The inner wall of the air duct 15 adjacent to the first air supply outlet 11 is tapered, and the flow cross section of the inner wall is gradually reduced along the airflow direction, as shown in fig. 5. In other words, the flow cross section of the duct 15 becomes gradually smaller in the direction of the air flow in the vicinity of the first blowing port 11.
The diversion member 30 is disposed in the air duct 15, and defines an air outlet gap 155 with an inner wall of the air duct 15. For example, as shown in fig. 5, the air guiding element 30 is spaced from both the upper wall 151 and the lower wall 152 of the air duct 15 adjacent to the first air supply outlet 11, so as to form an air outlet gap 155 with the upper wall 151 and the lower wall 152. The guide member 30 guides the supply air flow blown toward the first supply port 11 to the inner wall of the duct 15, so that the supply air flow gradually converges toward the center of the air flow and flows out of the first supply port 11 under the guidance of the tapered portions (i.e., the upper wall 151 and the lower wall 152) of the inner wall of the duct 15.
Due to the addition of the flow guide member 30, the flow cross section of the air outlet gap 155 is inevitably smaller than that of the original air duct 15, which makes the flow velocity of the supplied air faster. The high-speed air supply 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 15 to form a convergence effect, so that the wind power is very strong, the air supply distance is farther, the requirements of the wall-mounted air conditioner indoor unit on remote 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 diversion member 30 not only defines an air outlet gap 155 with the inner wall of the air duct 15 to play a role of increasing the wind speed, but also just guides the air supply flow to the air outlet gap 155, or forces the air supply flow to flow toward the air outlet gap 155, so as to force the air supply flow to be subjected to polymerization guidance of the tapered inner wall of the air duct 15, thereby forming the final polymerization air supply effect. The embodiment of the invention realizes a very good polymerization air supply effect only by improving the air duct 15 and additionally arranging the flow guide member 30, has very simple structure and lower cost, is easy to realize mass production and popularization, and has very ingenious conception.
As shown in fig. 4 and 5, the air guide member 30 has a hollow structure, and a spray hole 312 is formed at a side thereof facing the first air supply opening 11. The flow guide 30 is configured to produce water mist. During the flowing process of the air supply flow, a negative pressure environment is formed at the spray holes 312, so that water mist is mixed into the air supply flow and is blown out of the first air supply opening 11 together. That is, the high-speed air flow creates a negative pressure region around the spray holes 312, and the mist is "sucked" into the air flow and then "entrained" and blown out together
The wall-mounted air conditioner often causes indoor dryness in the operation process, and causes air conditioning diseases such as skin tightness, dry mouth and tongue, cold, cough and the like. The wall-mounted air conditioner indoor unit provided by the embodiment of the invention can humidify the indoor environment and adjust the indoor humidity in the process of refrigerating/heating. And the water mist converges into high-speed air supply airflow at the first air supply port, the mixing degree of the water mist and the air supply airflow is very high, the water mist can be conveyed to all places indoors along with the air supply airflow, and the diffusion range is wider. And need not to establish special fan or other supply-air outlets in addition, the structure is very simple ingenious.
Fig. 6 is an enlarged view of a guide in the wall-mounted air conditioning indoor unit of fig. 5.
In some embodiments, as shown in fig. 6, an ultrasonic oscillation component 35 is disposed in the flow guide 30 for atomizing the liquid water inside the flow guide 30. The ultrasonic oscillating unit 35 may be configured to atomize water into ultrafine particles of 1 to 5 micrometers and negative oxygen ions by ultrasonic high-frequency oscillation at 200 ten thousand times per second, and blow the ultrafine particles and the negative oxygen ions out through the atomizing holes 312 under the aforementioned negative pressure.
The guide member 30 may be further connected with a water injection pipe 33, and the water injection pipe 33 extends to the outside of the cabinet 10 so as to inject liquid water into the guide member 30 through the water injection pipe 33.
It can be understood that even if the wall-mounted air conditioner indoor unit does not perform a cooling/heating mode and has no high-speed outflow of the supply air, the water mist in the guide member 30 can still naturally diffuse out, thereby realizing a humidification process. Therefore, the wall-mounted air conditioner indoor unit can independently operate the humidification mode.
As shown in fig. 5, the wall-mounted air conditioner indoor unit may be an indoor unit of an air conditioner that performs cooling/heating through a vapor compression refrigeration cycle, and further includes a heat exchanger 40 and a blower 50. The heat exchanger 40 is disposed in the casing 10, and is configured to exchange heat with the air flow flowing through the casing to form a heat exchange air flow, i.e., a cold air or hot air, which may be a three-stage fin heat exchanger. The fan 50 is disposed in the casing 10, and is configured to promote indoor air to enter the casing 10, so that the indoor air exchanges heat with the heat exchanger 40 to become heat exchange air supply flow, and then promote the heat exchange air supply flow to each air supply outlet through the air duct 15.
The inventor considers that the wall-mounted air conditioner indoor unit is installed back-to-wall, and needs stronger forward air supply capacity. Therefore, in some embodiments, it is preferable that the first air blowing opening 11 is opened at the front of the casing 10, so that the air flow converges at the first air blowing opening 11 and then flows forward at a high speed, and the air blowing distance is further increased and the air blowing range is wider, as shown in fig. 1.
In some embodiments, as shown in fig. 5, the casing 10 is configured to make the rising angle of the airflow at the bottom section of the air outlet gap 155 greater than the declining angle of the airflow at the top section thereof, that is, make the rising angle of the lower wall 152 of the air duct greater than the declining angle of the upper wall 151, so that the airflow at the bottom section of the air outlet gap 155 drives the airflow at the remaining sections to flow upward and forward together, and fig. 5 illustrates the airflow direction with arrows, please refer to.
The upward-blowing angle refers to an included angle between the airflow direction at the bottom section of the air-out gap 155 and the horizontal plane, and the downward-tilting angle refers to an included angle between the airflow direction at the top section of the air-out gap 155 and the horizontal plane (if the airflow is blown out horizontally, the downward-tilting angle is 0 °). Because the rising angle of the air flow rising part is larger than the declining angle of the sinking part, the air flow mixed by a plurality of air flows integrally rises and flows. In the refrigeration mode, the rising and flowing cold air can fully avoid the human body and scatter downwards after reaching the highest point, so that the shower type refrigeration experience is realized. Moreover, the air flow is blown upwards to be beneficial to improving the air supply distance.
In some embodiments, as shown in fig. 4 and 5, the outlet of the duct 15 adjacent to the first supply opening 11 may be formed in a long strip shape with the length direction parallel to the transverse direction of the casing 10. Correspondingly, the flow guide member 30 is made in a rod shape extending in the lateral direction of the casing 10. Furthermore, the air guide 30 and the inner walls (the upper wall 151 and the lower wall 152, respectively) of the upper side and the lower side of the air duct 15 both define an air outlet gap 155, so that the air flow is divided into an upper air flow and a lower air flow by the air guide 30, and the two air flows respectively flow forward under the guidance of the upper wall 151 and the lower wall 152 of the air duct 15 and gradually approach and converge to form a converged air flow.
In some embodiments, as shown in fig. 1 and 4, the number of the first air blowing openings 11 may be multiple, and the multiple first air blowing openings 11 are arranged along the transverse direction of the casing 10, and different positions of the rod-shaped air guiding member 30 in the length direction respectively correspond to each of the first air blowing openings 11. The number of the spray holes 312 is plural, and one or more spray holes 312 are provided for each first supply outlet 11. For example, as shown in fig. 1 and 4, 4 spray holes 312 are provided for each first supply port 11. Compare in the scheme that only sets up a rectangular form supply-air outlet, this embodiment sets up a plurality of first supply-air outlet 11 side by side for every first supply-air outlet 11's air-out area is littleer relatively, does benefit to more and improves wind speed and wind pressure, thereby does benefit to and promotes polymerization air supply effect, makes the air current polymerization degree higher, and the air supply distance is farther.
Of course, in some alternative embodiments, the number of the first air supply outlet may also be one, and the first air supply outlet is an elongated strip (not shown) whose length direction is parallel to the transverse direction of the casing 10, so that the rod-shaped flow guiding element 30 corresponds to the elongated first air supply outlet, and the detailed structure is not described again.
Fig. 7 is a schematic view of the wall-mounted air conditioning indoor unit of fig. 5 in a down-blowing mode; fig. 8 is a schematic view of the wall-mounted air conditioning indoor unit of fig. 5 in a maximum blowing mode.
In some embodiments, the wall-mounted air conditioning indoor unit may further include a movable panel 20. The movable panel 20 is movably installed at the front side of the casing 10 to open or close the first blowing port 11. In this way, when the wall-mounted air conditioning indoor unit is in the off state, the movable panel 20 can close the first air supply outlet 11, so as to prevent the first air supply outlet 11 from being exposed to the outside and affecting the front appearance of the wall-mounted air conditioning indoor unit. This embodiment does not limit the movement of the movable panel 20 to open and close the first blowing port 11. The movable panel may be opened and closed by rotation, may be opened and closed by translation, or may be opened and closed by a combination of rotation and translation.
Further, as shown in fig. 5 to 8, a first air inlet 13 may be formed at the top of the casing 10, a second air inlet 14 may be formed at the front of the casing, and the second air inlet 14 is located above the first air outlet 11. The movable panel 20 has a closed position closing the second air intake vent 14 and the first air blowing port 11, as shown in fig. 3 and 7. The movable panel 20 also has an open position moved upward from the closed position and inclined forward at the upper end to open the first air blowing opening 11 and the second air intake opening 14, as shown in fig. 1, 2 and 5.
The inventor finds that the distance between the front section of the heat exchanger 40 of the wall-mounted air conditioner indoor unit and the front panel is too close, the gap is narrow, and the front section of the heat exchanger 40 does not normally face the air inlet at the top of the casing 10, so that the heat exchange of the front section of the heat exchanger 40 is adverse, and the improvement of the overall heat exchange efficiency of the heat exchanger 40 is affected. According to the invention, the second air inlet 14 is formed in the front part of the shell 10, so that the air inlet volume is increased, the heat exchange efficiency of the front section of the heat exchanger 40 is improved, and the overall energy efficiency of the air conditioner is improved. In addition, the present invention utilizes the movable panel 20 to open or close the second air inlet 14 and the first air outlet 11 at the same time, and the concept is very ingenious. The selection of the specific mechanism for driving the movable panel 20 to achieve the above-mentioned movement is various, and for example, the driving mechanism may include an up-down translation driving mechanism and a forward-backward push-pull driving mechanism. Or may include a translation mechanism and a rotation mechanism. These driving mechanisms are all common mechanisms in the air conditioning field, and are not described in detail herein.
In some embodiments, as shown in fig. 5 to 8, the bottom of the casing 10 may be provided with a second air outlet 12 which is open downwards and connected to the air duct 15. The air can be supplied to the lower part of the wall-mounted air conditioner indoor unit through the second air supply outlet 12. The downward air supply in the heating mode is more favorable for accelerating the temperature rising speed of the lower-layer space of the house, so that the human body can feel the heating effect more quickly.
The wall-mounted air conditioning indoor unit further includes a wind deflector 60, and the wind deflector 60 is rotatably installed at the cabinet 10 to open or close the second blowing port 12 and guide the blowing direction of the second blowing port 12. Further, an air guide mechanism such as a flap assembly may be attached to the second air supply port 12.
Therefore, the wall-mounted air conditioner indoor unit provided by the embodiment of the invention can run in the following modes.
Polymerization air supply mode: as shown in fig. 5, the air deflector 60 closes the second air supply outlet 12, the movable panel 20 opens the second air inlet 14 and the first air supply outlet 11, and the air is gathered and blown up by the first air supply outlet 11, so that the air flow avoids the human body, and then is scattered downwards after reaching the highest point, thereby realizing a "shower type" refrigeration experience. When the air conditioner operates in a refrigeration mode, air can be supplied according to a polymerization air supply mode.
A lower air supply mode: as shown in fig. 7, the air guide plate 60 opens the second air blowing port 12, closes the movable panel 20, and blows air downward through the second air blowing port 12. When the air conditioner operates in a heating mode, air can be supplied according to a lower air supply mode, so that the heating speed is accelerated.
