As shown in fig. 1 to 4, an indoor unit of an air conditioner according to an embodiment of the present invention may generally include a casing 100, a heat exchanger 400, a fan 500, and a movable cover 200. The heat exchanger 400 of the indoor unit of the air conditioner, the compressor of the outdoor unit of the air conditioner, the condenser of the outdoor unit, the throttling device, the connecting pipeline and other accessories jointly form a vapor compression refrigeration cycle system, and refrigeration/heating of the air conditioner is achieved.
The air-conditioning indoor unit can be a wall-mounted air-conditioning indoor unit or a floor-type air-conditioning indoor unit in the traditional sense, and can also be a cylindrical air-conditioning indoor unit with the structure shown in figures 1 and 2. The casing 100 is provided with an air inlet 120 and an air outlet 110, and particularly, for the structure shown in fig. 1 and 2, the casing 100 is cylindrical, and two axial sides are open to form the air inlet and the air outlet. The heat exchanger 400 is disposed in the casing 100 and configured to exchange heat with air entering the casing 100 from the air inlet 120 to form heat-exchange air (when the indoor unit of the air conditioner is in the cooling mode, the heat exchanger 400 cools the air to form heat-exchange air with a lower temperature, and when the indoor unit of the air conditioner is in the heating mode, the heat exchanger 400 heats the air to form heat-exchange air with a higher temperature). The heat exchanger 400 may be a finned heat exchanger, or another type of heat exchanger. The fan 500 is disposed in the cabinet 100 and configured to induce heat-exchange air to be blown toward the indoor space through the outlet 110. That is, the air conditioning indoor unit uses the fan 500 to realize forced convection heat exchange between air and the heat exchanger 400, thereby improving heat exchange efficiency, and the fan 500 also serves to supply air to the indoor space. The movable cover 200 is movably disposed at the air outlet 110, and configured to be movable away from the air outlet 110 to form an annular blowing gap 230 between an edge of the air outlet 110 and the air outlet 110, or movable close to the air outlet 110 to close the air outlet 110.
In the embodiment of the present invention, when the indoor unit of the air conditioner is not opened, the movable cover 200 may close the air outlet 110, so as to prevent dust or other impurities from entering the casing 100 and accumulating on the surfaces of the heat exchanger 400 and the fan 500 to affect the operation performance of the air conditioner. When the air conditioning indoor unit is operated, the movable cover 200 is moved to form the annular blowing gap 230 to blow air to the outside. In addition, the present invention can blow air around the plane of the movable cover 200 (as shown by the arrows in fig. 1) by using the annular air blowing gap 230, so that the air blowing direction is greatly expanded, and the temperature of the room is uniformly reduced or increased.
Fig. 2 to 4 illustrate a preferred connection between the movable cover 200 and the casing 100. As shown in fig. 2 to 4, the movable cover 200 has a plurality of mounting shafts 240 parallel to each other, and the casing 100 is provided with a plurality of mounting holes 190 at an edge near the outlet 110, and each mounting shaft 240 is axially translatably inserted into a corresponding mounting hole 190. Specifically, the number of the mounting shafts 240 may be four, which extend perpendicular to the movable cover plate 200, and the mounting holes 190 are formed on protrusions of the inner wall of the casing 100. The movable cover 200 can move in a translational manner along the axial direction (front-back direction in the figure) of the mounting shaft 240 away from the air outlet 110 (forward), forming an annular air supply gap 230 (fig. 4) or close to the air outlet 110 (backward), so as to close the air outlet 110 (fig. 3). At this time, the previous annular blowing gap 230 disappears.
In the embodiment of the present invention, it is preferable to move the movable cover 200 in a manner manually operated by a user without designing a complicated driving mechanism and an electric control program. Moreover, the manual adjustment method enables the user to adjust the moving distance of the movable cover 200 more directly, and adjust the air outlet area of the annular air supply gap 230.
In addition, the mounting shaft 240 and the mounting hole 190 can be tightly fitted to each other, so that the relative position between the mounting shaft 240 and the mounting hole 190 can be kept, and the movable cover 200 can be kept in position.
In some embodiments, as shown in fig. 1 to 4, the movable cover plate 200 may further include a blowing port 210 for allowing the heat-exchanged air to be blown out from the casing 100. The user opens the annular air supply gap 230 and the air supply opening 210 alternatively or simultaneously, and controls the air supply direction of the air supply opening 210, so that various air supply modes are realized, and diversified air supply requirements of the user are met.
Preferably, a plurality of air-guiding grills 300 parallel to each other may be further provided at the air blowing port 210, and both ends of each air-guiding grille 300 in the length direction are hinged to the movable cover plate 200 to be pivotable about an axis parallel to the length direction thereof, so that the plurality of air-guiding grills 300 simultaneously pivotally change the air blowing direction of the air blowing port 210. In addition, it is also possible to allow the air guide grid plate 300 to be pivoted to an angle in synchronization, in which the plurality of air guide grid plates 300 close the air blowing ports (as shown in fig. 1 and 2). The air blowing opening 210 is preferably square in order to conveniently arrange the air guide grill 300.
Specifically, the air deflection grill panel 300 may be extended horizontally, vertically, or obliquely. When the air guide grid plate 300 extends horizontally, up-and-down air sweeping can be realized, and when the air guide grid plate 300 extends vertically, left-and-right air sweeping can be realized. In the embodiment of fig. 1 to 4, only the horizontally extending air guiding grid plate structure is illustrated, and fig. 3 and 4 illustrate a state in which the air guiding grid plate 300 guides air downward, and the direction of the air flow is indicated by an arrow.
When the air conditioner indoor unit operates, a user may manually rotate the angle of the air-guiding grill 300 to adjust the wind direction. Of course, an electric mode may also be adopted, so that the stepping motor drives the air guiding grid plate 300 to rotate, and the specific structural form is generally used in the prior art and is not described herein again. In addition, two groups of air guide grid plates can be arranged, one group of air guide grid plates extends vertically, the other group of air guide grid plates extends horizontally, the two groups of air guide grid plates are matched with each other to enlarge an air supply angle, the specific structure is common in the prior art, and detailed explanation is omitted.
In some embodiments, as shown in fig. 1 to 4, the air outlet 110 may be located at the front side of the casing 100, and the air inlet 120 may be located at the rear side of the casing 100. When air is supplied through the annular air supply gap 230, the air outlet of the annular air supply gap is blown out along a vertical surface approximately, and the annular air supply gap cannot blow to human bodies to cause discomfort. It is preferable that the air outlet 110 and the movable cover 200 are both circular to improve the appearance, and when the air outlet 110 is circular, the annular air supply gap 230 is circular to provide more uniform air supply. In addition, the intake vent 120 is preferably provided with an intake grill 130 for allowing air to pass therethrough.
The structure of the above-described embodiment of the present invention is preferably configured such that the axial flow fan is disposed with its rotation axis perpendicular to the movable cover 200. As shown in fig. 1 to 4, the casing 100 is a cylinder with a horizontal axis, the air inlet 120 and the air outlet 110 are located on a vertical plane, the movable cover 200 extends vertically, and the rotation axis of the axial flow fan 500 extends in a horizontal direction. Because axial fan's wind blows off along the axial, and center department wind pressure is less, and the edge wind pressure is great, through setting up annular air supply clearance 230, makes axial fan 500 high-pressure wind in edge disperse to blow off, makes its wind pressure suitably reduce to be closer with the wind pressure of center department, can make wind more even on the whole.
In some embodiments, as shown in fig. 1 to 4, the heat exchanger 400 may have a flat plate structure, and the heat exchanger of the flat plate structure is matched with the axial flow fan to improve heat exchange efficiency and is disposed behind the fan 500. In some alternative embodiments, the heat exchanger 400 may also be disposed in front of the fan 500.
In the above embodiments of the present invention, the casing is cylindrical, so that the indoor unit of the air conditioner has only one set of air outlet structures, and each air outlet structure includes one of the air inlet 120, the air outlet 110, the fan 500, and the movable cover 200.
In some other embodiments not illustrated in the drawings, one or more groups of air outlet structures may be provided as appropriate according to the difference of the overall shape of the air conditioning indoor unit. For example, in the case of a horizontally extending elongated wall-mounted air conditioning indoor unit, two or three air outlet structures may be provided in a lateral arrangement. For the vertical strip-shaped floor type air conditioner indoor unit, two or three air outlet structures which are longitudinally arranged can be arranged. The detailed structure of the above embodiments is not described herein.
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.
