A wall-mounted air conditioning indoor unit according to an embodiment of the present invention will be described with reference to fig. 1 to 3. Where the orientations or positional relationships indicated by the terms "front", "back", "upper", "lower", "top", "bottom", "inner", "outer", "lateral", etc., are based on the orientations or positional relationships shown in the drawings, they are merely for convenience of description and to simplify the description, and do 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 therefore should not be construed as limiting the invention.
As shown in fig. 1 to 3, a wall-mounted air conditioner indoor unit according to an embodiment of the present invention may generally include a casing 10, first and second heat exchangers 21 and 22, an air duct member 40, first and second crossflow blowers 31 and 32, and first and second baffles 51 and 52.
The housing 10 is provided with an air inlet 13 and two air outlets, which are a first air outlet 11 facing forward and a second air outlet 12 facing downward. The air inlet 13 may be provided with a grille. The first outlet 11 may be disposed at the bottom of the front surface of the casing 10, and the second outlet 12 may be disposed at the front of the bottom surface of the casing 10. The air duct member 40 is disposed in the casing 10, and defines two air ducts, namely a first air duct 41 and a second air duct 42, which are respectively communicated with the first air outlet 11 and the second air outlet 12. Two heat exchangers, a first heat exchanger 21 and a second heat exchanger 22, are disposed in the housing 10, and are respectively opposite to the first air duct 41 and the second air duct 42. The wall-mounted air conditioning indoor unit may be an indoor unit of an air conditioning system that performs cooling/heating by a vapor compression refrigeration cycle system. The first heat exchanger 21 and the second heat exchanger 22 are used for exchanging heat with air entering the housing 10 from the air inlet 13 to form heat exchange air. Specifically, when the air conditioner is in a refrigeration mode, the heat exchange air is cold air; when the air conditioner is in a heating mode, the heat exchange air is hot air. The first cross flow fan 31 and the second cross flow fan 32 are disposed in the first air duct 41 and the second air duct 42, respectively. Specifically, the crossflow blower is disposed at an inlet of the air duct. A first shutter 51 and a second shutter 52 are mounted to the casing 10 for opening or closing the first outlet port 11 and the second outlet port 12, respectively. The first cross flow fan 31 and the second cross flow fan 32 are configured to be turned on alternatively or simultaneously, so that the wall-mounted air conditioner indoor unit has multiple air supply modes.
The embodiment of the utility model provides an in, wall-hanging air conditioning indoor set has set up forward first air outlet 11 and downward second air outlet 12, enlarges the air supply angle scope of wall-hanging air conditioning indoor set. And because each air outlet is matched with the baffle, the air supply direction can be selected according to different modes of refrigeration and heating, and comfortable air supply is realized. Specifically, in the cooling mode, the second air outlet 12 can be closed by the second baffle 52, the first air outlet 11 can be opened by the first baffle 51, forward air supply or forward and upward air supply is realized, cold air avoids a human body, the cold air reaches the highest point and then falls down, and a 'shower type' cooling experience is realized, as shown in fig. 3. In the heating mode, the first air outlet 11 can be closed by the first baffle 51, the second air outlet 12 can be opened by the second baffle 52, and the hot wind can blow directly to the bottom surface vertically and downwards to achieve foot warming experience, as shown in fig. 2.
In addition, the first air outlet 11 and the second air outlet 12 can be opened, and the first cross flow fan 31 and the second cross flow fan 32 are simultaneously started, so that air supply with large air volume is realized. When the first crossflow blower 31 and the second crossflow blower 32 are simultaneously turned on, the sides thereof facing the first heat exchanger 21 and the second heat exchanger 22 are turned in the opposite directions. That is, as shown in fig. 1, the first through-flow fan 31 is rotated clockwise, and the second fan is rotated counterclockwise. The inventor conducts theoretical analysis, and therefore the suction efficiency of the two cross-flow fans can be effectively improved.
The embodiment of the utility model provides a not simply set up two air outlets, but all set up an wind channel, a heat exchanger and a cross-flow fan for every air outlet to form two sets of independent air supply systems. The shape of each air channel, the position and the specification of the cross-flow fan are designed independently and in a matched mode according to the air outlet of each air channel, so that the air supply resistance of the air supply system is smaller, and the energy efficiency of the cross-flow fan is higher.
In some embodiments, the first heat exchanger 21 and the second heat exchanger 22 are arranged in parallel in the refrigeration system. Namely, each heat exchanger, the compressor, the condenser and the throttling device form a circulation loop to form two refrigeration circulation subsystems, and the two subsystems share the compressor, the condenser and the throttling device. In this way, the two heat exchangers can be controlled independently, and activation or deactivation of one heat exchanger does not affect the other heat exchanger. When only one air outlet is opened, only the matched heat exchanger is started, and the other heat exchanger is stopped. Therefore, the meaningless energy loss caused by the fact that another heat exchanger runs but does not have a fan to carry out forced convection heat exchange can be avoided, and the frosting risk of the heat exchanger in the refrigeration mode can be reduced. If two heat exchangers set up for establishing ties, the fan that certain heat exchanger corresponds is closed, then near this heat exchanger does not force the convection current heat transfer, makes its heat transfer unfavorable, and cold volume can't in time distribute away, will lead to frosting. Frosting also has a serious adverse effect on the heat exchange performance of the heat exchanger.
In some embodiments, as shown in fig. 1, the first heat exchanger 21 and the second heat exchanger 22 may be two-stage, and they are structurally connected to each other to form a three-stage structure. Therefore, the two heat exchangers are basically consistent with the existing commonly-used three-section heat exchanger in the shape structure, so that the existing tooling can be used in the production and assembly processes, and the cost is reduced; on the other hand, the housing can be prevented from being improved too much.
In some embodiments, as shown in fig. 1, the upper end of the first baffle 51 may be rotatably mounted at the upper edge (point a) of the first outlet 11, and the front end of the second baffle 52 may be rotatably mounted at the front edge (point B) of the second outlet 12. During the heating mode, rotate second baffle 52 to vertical extension or the position that is close vertical extension, do benefit to and lead hot-blast downwardly, promote warm foot experience, as fig. 2. Of course, in the cooling mode, the second baffle 52 may be optionally rotated upward to make the front end higher than the rear end, so that the second baffle 52 raises and guides the cool air coming out from the first air outlet 11.
Due to the guiding function of the second baffle 52, the front edge (point B) of the second air outlet 12 can be higher than the rear edge (point C) thereof, so that the air outlet direction of the second air outlet 12 is also inclined forward at a certain angle, and the phenomenon that the air supply range is too small and the heating speed is affected due to the fact that the air outlet direction is completely vertical and downward is avoided.
In some embodiments, as shown in FIGS. 1-3, the axes of the second crossflow blower 32 and the first crossflow blower 31 may be parallel to each other, with the second crossflow blower 32 being located above and behind the first crossflow blower 31. The size of the two cross-flow fans in the front-back direction is smaller, and the phenomenon that the wall-mounted indoor unit is too thick due to the arrangement of the two cross-flow fans is avoided. Further, the common plane (two axes are parallel and certainly in one plane) of the axes of the first crossflow blower 31 and the second crossflow blower 32 can be formed at an angle of between 30 ° and 40 ° with respect to the horizontal plane, as shown in fig. 2. Therefore, the problem that the arrangement direction of the two cross-flow fans is too close to the vertical direction (the extreme position is that the second cross-flow fan 32 is arranged right above the first cross-flow fan 31) to cause that the first cross-flow fan 31 is too far away from the air inlet 13 and the airflow in the second air duct 42 is too tortuous to bring adverse effects to the air supply efficiency can be avoided.
In some embodiments, referring to fig. 2, the first outlet 11 can be designed to be smaller, and the second outlet 12 can be designed to be larger, so that the first outlet 11 is more suitable for cooling high-speed air supply, and the second outlet 12 is suitable for heating low-speed air supply. The second air outlet 12 has a lower air speed, so the design is larger to meet the air quantity requirement. Further, the ratio of the distance between the upper and lower edges of the first outlet 11 (i.e., the distance between points AB) to the distance between the front and rear edges of the second outlet 12 (i.e., the distance between points BC) can be set to 0.4 to 0.6, so as to optimally satisfy the requirements of air volume and air speed.
In some embodiments, the first crossflow blower 31 can be rated for a larger volume than the second crossflow blower 32. The inventor has recognized that since the first air outlet 11 is mainly used to blow air forward or even blow air upward, the blowing resistance is greater. The second air outlet 12 is mainly used for downward air supply, and air supply resistance is smaller, so that the rated air volume of the first cross flow fan 31 is especially larger than that of the second cross flow fan 32, and cost waste and electric quantity waste caused by the arrangement of two identical high-power fans are avoided.
In some embodiments, as shown in FIG. 3, the air duct component 40 includes a first volute 401, an intermediate volute 403, and a second volute 402 arranged front-to-back. Between the first volute 401 and the middle volute 403 is a first air duct 41, and between the middle volute 403 and the second volute 402 is a second air duct 42. The two air ducts share the middle volute 403, and the middle volute 403 is in a thin plate shape, so that the distance between the two air ducts is shorter, and the wall-mounted air conditioner indoor unit is lighter and thinner.
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.
