As shown in fig. 1 and 2, a wall-mounted air conditioning indoor unit according to an embodiment of the present invention may generally include a case 10, an evaporator 20, at least one fan, an upper baffle 50, and a lower baffle 60. The wall-mounted air conditioner indoor unit is matched with an air conditioner outdoor unit for use, and a vapor compression refrigeration cycle system is adopted to realize refrigeration/heating of indoor environment.
The casing 10 defines an accommodation space to accommodate various components of the wall-mounted air conditioning indoor unit. The housing 10 has an air inlet 101 at a rear side thereof and an upper air outlet 102 and a lower air outlet 103 arranged up and down at a front side thereof. The evaporator 20, which may be a finned evaporator, is disposed within the housing 10. The fan is disposed in the casing 10, and is configured to cause indoor air to enter the casing 10 from the air inlet 101, to exchange heat with the evaporator 20 to form heat-exchange air, and to cause the heat-exchange seal to be blown out from the upper air outlet 102 and/or the lower air outlet 103. The evaporator 20 may be disposed between the blower and the air inlet 101 so that the air of the blower is more smoothly blown toward the air outlet. Of course, it is also possible to arrange the fan between the evaporator 20 and the intake opening 101. The upper shutter 50 is configured to controllably open/close the upper air outlet 102, and the lower shutter 60 is configured to controllably open/close the lower air outlet 103.
The wall-mounted air conditioner indoor unit with the existing structure is only provided with a forward air outlet at the bottom of the shell 10, is not beneficial to air supply upwards, and cannot realize upward vertical air supply. In the embodiment of the invention, the upper air outlet 102 is used for blowing air upwards, and the lower air outlet 103 is used for blowing air downwards, so that the angles of the upper air blowing and the lower air blowing are increased, and the problem that the air directly blows a human body is avoided. Preferably, the upper air outlet 102 is opened towards the front lower part, and the lower air outlet 103 is opened towards the front lower part, so that vertical upward and vertical downward air blowing is more conveniently realized.
In addition, in the embodiment of the present invention, both the upper air outlet 102 and the lower air outlet 103 can be controlled to be opened and closed, and a user can open only the upper air outlet 102, only the lower air outlet 103, or open both the upper air outlet 102 and the lower air outlet 103 as needed, so that the air supply modes are greatly enriched. For example, as shown in fig. 4, when the air conditioner is refrigerating, only the upper air outlet 102 is opened, and the lower air outlet 103 is closed, so that the cool air can be blown upwards, and then flows downwards to balance the temperature of the whole indoor space. For example, as shown in fig. 3, when the air conditioner heats, only the lower air outlet 103 may be opened, and the upper air outlet 102 may be closed, so as to facilitate the downward blowing of hot air, and make the hot air flow upward to make the temperature of the whole indoor space more balanced. Or, no matter during refrigeration or heating, the two air outlets can be opened simultaneously, and the air outlet angle of the indoor unit is increased, so that the indoor rapid refrigeration or heating can be realized.
In some embodiments, the housing between the upper outlet 102 and the lower outlet 103 is the front panel 13. The upper baffle 50 can be controlled to slide between a position completely hidden behind the front panel 13 and a position completely closing the upper air outlet 102, so as to adjust the air outlet area of the upper air outlet 102. For example, the upper baffle 50 may be made to completely open the upper air outlet 102, completely close the upper air outlet 102, or open the upper air outlet 102 to a certain degree, such as 30%, 50%, etc. Likewise, the lower baffle 60 can be controlled to slide between a position completely hidden behind the front panel 13 and a position completely closing the lower outlet 103, so as to adjust the outlet area of the lower outlet 103.
Specifically, in an embodiment not illustrated in the drawings, two sets of electric rack and pinion mechanisms may be employed to drive the movement of the upper and lower baffles 50, 60. A first rack is arranged on the upper baffle 50, a first stepping motor is arranged on the front panel 13, a first gear is arranged on the first stepping motor, and the first gear is meshed with the first rack. The first stepping motor rotates to drive the first gear to rotate, and the first gear rotates to drive the first rack to translate so as to drive the upper baffle 50 to slide. Similarly, a second rack is arranged on the lower baffle 60, a second stepping motor is arranged on the front panel 13, and a second gear is arranged on the second stepping motor and meshed with the second rack so as to drive the lower baffle 60 to slide.
In some embodiments, the upper baffle 50, the lower baffle 60 and the front panel 13 are all arc structures with convex front middle portions, so as to facilitate the extension and retraction of the upper baffle 50 and the lower baffle 60, and at the same time, facilitate the arrangement of the upper air outlet 102 towards the front upper side, and the arrangement of the lower air outlet 103 towards the front lower side, which is also more beautiful in appearance of the wall-mounted air conditioner indoor unit.
In some embodiments, as shown in fig. 5, the front panel 13 may be a louver structure, which is composed of a plurality of grills 131 arranged in parallel with each other, and a ventilation gap is formed between adjacent grills 131 to allow the heat exchange wind to blow forward through the front panel 13 to the indoor when opened.
The grille strips can not rotate and are always kept in a ventilation state, so that air can be supplied forwards through the front panel 13 when the wall-mounted air conditioner indoor unit is started.
It is also possible to have a plurality of grill bars that can be rotated synchronously to change the wind direction. As shown in fig. 5, each of the plurality of grill bars 131 extends in the horizontal direction, and when they rotate in synchronization, the wind direction can be adjusted in the vertical direction. When the plurality of grid bars 131 rotate up and down in a reciprocating manner, the wind can be swung up and down. Of course, a plurality of grills can also extend along the vertical direction so as to realize the adjustment of the left and right wind direction and the left and right wind swinging.
This embodiment can blow forward through making front panel 13, makes it and last air outlet 102, lower air outlet 103 together, has realized the comprehensive air-out of three direction about in, has increased the air supply angle, has promoted refrigeration/heating speed. And further enriches the air supply modes. For example, at least the following air supply modes are included: only the air is blown forward as shown in fig. 5, and the air outlet and the lower air outlet 103 are closed; the forward air supply is combined with the downward air supply as shown in fig. 6; the forward blowing is combined with the upward blowing as shown in fig. 7.
In some embodiments, as shown in fig. 1, the number of the fans is two, and the two fans are preferably an upper crossflow fan 41 and a lower crossflow fan 42, respectively, which have axes extending in the left-right direction and are arranged in the up-down direction. Moreover, a partition member 30 is provided on the front sides of the two fans. The upper surface 31 of the partition member 30 and the upper inner wall 11 of the casing 10 constitute an upper duct 91 to guide the wind of the upper cross flow fan 41 toward the upper wind outlet 102. And the lower surface 32 of the partition member 30 and the lower inner wall 12 of the casing 10 constitute a lower duct 92 to guide the wind of the lower cross flow fan 42 to the lower wind outlet 103.
Preferably, the front side surface 33 of the partition member 30 and the front side inner wall (i.e., the front panel 13) of the casing 10 may constitute an intermediate air duct 93 connecting the upper air duct 91 and the lower air duct 92. Thus, when only the lower outlet 103 is opened, as shown in fig. 3, the air of the upper cross flow fan 41 can be collected into the lower duct 92 through the middle duct 93. When only the upper outlet 102 is opened, as shown in fig. 4, the air of the lower cross-flow fan 42 can be collected into the lower air duct 92 through the middle air duct 93.
Of course, in some alternative structures, the partition member 30 may completely separate the upper duct 91 from the lower duct 92, so that the wind at the upper wind outlet 102 completely originates from the upper cross flow fan 41, and the wind at the lower wind outlet 103 completely originates from the lower cross flow fan 42.
For the indoor unit of the air conditioner with the same specification, two cross-flow fans with smaller power may be provided as described in this embodiment, or only one cross-flow fan with larger power may be provided (the power is approximately equal to the sum of the two smaller cross-flow fans). However, in some cases, such as when the cooling/heating requirement is low, the air volume requirement is low, the rotating speed of the high-power cross-flow fan is small by starting the high-power cross-flow fan, and the operating efficiency of the fan at the low rotating speed is low. Therefore, in the embodiment, two cross-flow fans with smaller power are adopted to replace one larger cross-flow fan, and only one cross-flow fan is started when the air volume requirement is low, so that the rotating speed is higher, and the operating efficiency is higher. In addition, the two cross-flow fans are respectively matched with the upper air outlet 102 and the lower air outlet 103, and the partition part 30 is arranged to form the upper air duct 91, the lower air duct 92 and the middle air duct 93, so that the distance between the fans and the air outlets is shorter, and the air supply efficiency is higher.
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.
