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 7. Where the terms "front", "back", "upper", "lower", "top", "bottom", "inner", "outer", "lateral", etc. indicate orientations or positional relationships based on those shown in the drawings, this is for convenience in describing the invention and to simplify the description, and does 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 thus, should not be taken to be limiting of the invention. The direction of the airflow is indicated by arrows.
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 of 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 bottom of the casing 10 is opened with a downward open lower air supply outlet 12, and an air duct 15 communicating with the lower air supply outlet 12 is defined inside. 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 lower air outlet 12 is used to blow the air flow in the casing 10 into the room to condition the indoor air. The air flow can be cold air produced by the wall-mounted air conditioner indoor unit in a refrigeration mode, hot air produced in a heating mode, or fresh air introduced in a fresh air mode, and the like. The number of the lower blowing openings 12 may be one or a plurality of lower blowing openings arranged side by side. The wall-mounted air conditioner indoor unit can supply air to the right lower part of the wall-mounted air conditioner through the lower air supply outlet 12, and the downward air supply of the air conditioner is more favorable for accelerating the temperature rising speed of the lower-layer space of a house during heating, so that a human body can feel the heating effect more quickly.
The inner wall of the duct 15 adjacent to the lower supply outlet 12 is tapered such that the flow cross section of the duct 15 becomes gradually smaller in the airflow direction (see the rear wall 152 and the third wall 153 in fig. 6). In other words, the flow cross section of the duct 15 becomes gradually smaller in the direction of airflow near the lower supply outlet 12.
The guiding member 30 is disposed in the air duct 15 and adjacent to the lower air supply opening 12, and is used for guiding the air flow blowing to the lower air supply opening 12 to the inner wall of the air duct 15, so that the air flow gradually converges towards the center of the air flow and flows out of the lower air supply opening 12 under the guidance of the tapered part of the inner wall of the air duct 15.
Specifically, the flow guide member 30 is additionally provided, so that the flow cross section of the air duct 15 is reduced, and the air outlet speed is increased. The high-speed airflow is gradually converged towards the center of the airflow in the downward 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 stronger, the air supply distance is longer, the high-speed airflow can reach the ground more powerfully, and the heating effect is improved. In the embodiment of the invention, the flow guide piece 30 not only reduces the flow cross section of the air duct 15 and improves the air speed, but also can guide the air flow to the inner wall of the air duct 15 exactly, or extrude the air flow to the inner wall of the air duct 15 so as to force the air flow to be subjected to polymerization and guide of the tapered inner wall of the air duct 15, thereby forming the final polymerization air supply effect, and the invention has very simple structure and ingenious concept; and the cost is lower, easily realize the volume production and promote.
As shown in fig. 4, the guide member 30 may be formed in a bar shape extending in a lateral direction of the casing 10. The number of the lower air supply outlet 12 may be one, and the lower air supply outlet is a long bar shape extending along the transverse direction of the casing 10, so that the bar-shaped flow guide member 30 corresponds to the long bar-shaped lower air supply outlet 12; alternatively, the lower supply port 12 may be plural in number and arranged in the lateral direction of the casing 10. As shown in fig. 5, the guide member 30 may have a curved surface 31 protruding outward of the lower outlet 12 and a V-shaped surface 32 protruding inward of the lower outlet 12. The V-shaped surface 32 of the flow guide member 30 faces the inner side of the lower supply port 12, which is very advantageous for splitting the air flow into two parts and guiding the two parts to two sides, so that the guiding is smoother and the air flow resistance is smaller. The curved front surface 31 of the flow guiding member 30 protruding towards the outside of the lower air supply outlet 12 can guide the airflow nearby to flow close to the surface so as to gradually converge towards the center direction of the surface, so as to exert a converging effect on the airflow together with the tapered inner wall of the air duct 15, thereby improving the airflow converging effect.
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 an air flow flowing through the casing to form a heat exchange air flow, i.e., a cold air or a hot air, which may be a three-stage fin heat exchanger. The fan 50 is disposed in the casing 10, and is configured to force indoor air to enter the casing 10, so that the indoor air and the heat exchanger 40 complete heat exchange to form heat exchange air flow, and then force the heat exchange air flow to each air supply opening through the air duct 15.
Fig. 6 is a schematic view of the wall-mounted air conditioning indoor unit of fig. 5 in a front blowing mode.
As shown in fig. 5 and 6, in some embodiments, 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 and arranged at the lower outlet 12 side by side with the guide member 30 in the front-rear direction, that is, the guide member 30 is positioned behind the wind deflector 60, as shown in fig. 5. Alternatively, the deflector 30 is positioned in front of the air deflector 60 (not shown). The air guide plate 60 is used to open and close the space between the air guide member 30 and the inner wall of the air duct 15 and guide the airflow direction thereof. As shown in fig. 5 and 6, for example, the rear end of the baffle 30 is spaced a relatively small distance from the inner wall (rear wall 152) of the air chute 15. The front end of the air guide 30 and the inner wall (third wall 153) of the air duct 15 form a large space, and the air guide plate 60 is disposed in the large space. The arrangement makes the air output of the lower air supply outlet 12 larger. A gap may be further formed between the air guide plate 60 and the air guide 30 to allow the air flow to flow out. In this way, even when the air deflector 60 is in the closed state (as shown in fig. 6), the front and rear sides of the air guide member 30 can still perform the air gathering and blowing.
The air deflector 60 can be configured such that its pivot 61 is located right above it (see fig. 6) when it is in the closed state, so as to be rotatable to the inside of the air duct 15 (see fig. 5), and the air deflector 60 guides the air flow to the inner wall (third wall 153) of the air duct 15 inside the air duct 15, thereby increasing the collective air supply effect.
In some embodiments, as shown in fig. 1, 5 and 6, the front portion of the casing 10 is further opened with a front air supply outlet 11, which is communicated with an air duct 15 for supplying air forwards. The arrangement of the front air supply outlet 11 and the lower air supply outlet 12 enables the air supply angle range of the wall-mounted air conditioner indoor unit to be larger. The front air supply outlet 11 and the lower air supply outlet 12 can be opened alternatively or simultaneously, so that the wall-mounted air conditioner indoor unit has more air supply modes to meet different air supply requirements of refrigeration and heating. For example, the front blowing port 11 may be opened to blow air forward during cooling; the lower air supply outlet 12 can be opened during heating so as to supply air downwards to facilitate quick heating. Or, the front air supply outlet 11 and the lower air supply outlet 12 can be opened simultaneously for cooling and heating so as to supply air with large air volume and accelerate the cooling/heating speed.
As shown in fig. 6, the air duct 15 may be defined by a front wall 151, a rear wall 152 located behind and below the front wall 151, and a third wall 153 located directly below the front wall 151. The front wall 151 and the third wall 153 form a front air outlet 11 with a gap therebetween, and the rear wall 152 and the third wall 153 form a lower air outlet 12 with a gap therebetween.
The third wall 153 may be formed to extend obliquely upward from rear to front so that the flow cross-section of the duct 15 adjacent to the front blowing port 11 and the lower blowing port 12 becomes gradually smaller in the air flow direction. In other words, by arranging the third wall 153 in the inclined shape, the third wall 153 and the front wall 151 form a tapered shape near the front blowing opening 11, so that the outlet airflow at the front blowing opening 11 also has a certain convergent blowing effect, so that the wind force is stronger, and the forward blowing distance is longer. Meanwhile, the third wall 153 and the rear wall 152 are also tapered at portions adjacent to the lower blowing port 12, and also form a collective blowing effect.
In some embodiments, as shown in fig. 1-6, the wall-mounted air conditioning indoor unit may further include a movable panel 20. A movable panel 20 is movably installed at a front side of the casing 10 to open or close the front 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 front air outlet 11, so as to prevent the front air 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 front air blowing port 11. The movable panel 20 may be opened and closed by rotation, may be opened and closed by translation, or may be opened and closed by combination of rotation and translation.
Further, as shown in fig. 1 to 6, the top of the casing 10 may be provided with an upper air inlet 13, the front thereof may be provided with a front air inlet 14, and the front air inlet 14 may be located above the front air inlet 11. The movable panel 20 has a closed position closing the upper intake opening 13 and the front blow opening 11, as shown in fig. 3 and 5. 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 front supply air outlet 11 and the front supply air outlet 14, as shown in fig. 1, 2 and 6.
The inventor finds that the front section of the heat exchanger 40 of the wall-mounted air conditioner indoor unit is too close to the front panel, the gap is narrow, and the front section of the heat exchanger 40 is not aligned with the air inlet at the top of the machine shell, 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 front air inlet 14 is arranged at the front part of the shell 10, so that the air inlet amount 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 opens or closes the front air inlet 14 and the front air outlet 11 simultaneously by using the movable panel 20, and the conception 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.
Fig. 7 is a schematic view of the wall-mounted air conditioning indoor unit of fig. 5 in a maximum blowing mode.
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 guide plate 60 opens the lower air outlet 12, and the movable panel 20 closes the front air inlet 14 and the front air outlet 11, so that air is blown through the lower air outlet 12. Meanwhile, the lower air supply outlet 12 also has a convergent air supply effect, so that air flow can reach the ground more strongly. When the air conditioner runs in a heating mode, air can be supplied according to a polymerization air supply mode, so that the heating speed can be increased.
A front air supply mode: as shown in fig. 6, the air deflector 60 is in a closed state, and the movable panel 20 opens the front air inlet 14 and the front air supply outlet 11 to supply air through the front air supply outlet 11, and the main part of the airflow is blown out forward away from the human body, and then is scattered downward after reaching the highest point, so that a "shower type" refrigeration experience is realized. When the air conditioner runs in a refrigeration mode, air can be supplied according to a front air supply mode. A small part of the air flow is blown downwards from the lower air supply opening 12 through the gap beside the flow guide member 30.
The maximum air supply mode is as follows: as shown in fig. 7, the air deflector 60 is opened, and the movable panel 20 opens the front air inlet 14 and the front air outlet 11, and blows air forward from the front air outlet 11 and downward from the lower air outlet 12, including downward convergent air blowing. When the air conditioner operates in a cooling or heating mode, the maximum air supply mode can be selected.
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.
