Furthermore, in the indoor unit of the air conditioner, the fresh air fan comprises a water tank, a second motor and a water stirring wheel. When necessary, the theory of watering stirs the water in the water tank, carries out the humidification to the inspiratory air of new trend fan, avoids introducing outdoor dry new trend to lead to indoor humidity to reduce, and simple structure is ingenious, and is very practical.
Further, in the fresh air fan and the indoor unit of the air conditioner, the fresh air fan is provided with an air return opening, and can suck non-fresh air flow, such as indoor air or heat exchange air flow (cold air or hot air). Can make return air inlet and new trend import open simultaneously for blow off after new trend air current and heat transfer air current or the room air mixture, accomplish the hybrid process of new trend and other air currents in advance, accelerated the renewal speed of room air. And when the fresh air demand does not exist indoors, the fresh air fan bears the blowing work of the heat exchange air flow, and the indoor refrigerating/heating speed is accelerated. In a word, the function of new trend fan has greatly been richened to the setting of return air inlet, and the design is very ingenious.

Fig. 1 is a schematic structural view of an indoor unit of an air conditioner according to an embodiment of the present invention; fig. 2 is another angle view of the indoor unit of the air conditioner shown in fig. 1; FIG. 3 is a schematic structural diagram of a fresh air blower according to one embodiment of the present invention; FIG. 4 is a schematic view of the fresh air blower in a state where the fresh air inlet is closed and the first fresh air outlet is open; fig. 5 is a schematic view of the state of the fresh air fan when the first fresh air outlet is closed and the fresh air inner outlet is opened.
As shown in fig. 1 to 5, an indoor unit of an air conditioner according to an embodiment of the present invention may generally include a casing 10 and a fresh air blower 20.
The cabinet 10 defines a receiving space for receiving various parts of the indoor unit of the air conditioner, including an evaporator, a heat exchange fan, etc. The casing 10 is provided with a first fresh air outlet 14 for discharging fresh air flow.
The fresh air fan 20 is installed inside the casing 10 for promoting the flow of the fresh air flow. The fresh air blower 20 includes a housing 100. The casing 100 is provided with a fresh air inlet 110 for sucking fresh air flow, a first fresh air outlet 124 connected to the first fresh air outlet 14, and a fresh air inner outlet 126 facing the inside of the casing 10. The fresh air inlet 110 may be ducted to the outdoor environment to introduce fresh air flow.
The fresh air fan 20 is configured to: the first fresh air outlet 124 and the fresh air inlet 126 are opened simultaneously or alternatively, so that the fresh air flow flows to the indoor environment and the inside of the cabinet 10 simultaneously or to either one of them.
Specifically, for example, as shown in fig. 4, the first fresh air outlet 124 is opened, the fresh air inner outlet 126 is closed, and the fresh air flow flows out from the first fresh air outlet 124 and then flows directly to the indoor environment from the first fresh air outlet 14 of the casing 10. When the indoor user only has fresh air demand and does not have refrigeration and heating demands, the air can be selectively discharged from the first fresh air outlet 124, so that the heat exchange part (a heat exchanger, a heat exchange fan, a heat exchange air outlet and the like) of the air conditioner does not work.
Or, for example, as shown in fig. 5, the first fresh air outlet 124 is closed, the fresh air inner outlet 126 is opened, and the fresh air flow flows from the fresh air inner outlet 126 to the inside of the casing 10, mixes with the heat exchange air flow in the casing 10 or directly flows to the heat exchanger for heat exchange, and then is discharged to the indoor environment through the heat exchange air outlet 12 of the casing 10. When the air conditioner needs to exchange fresh air while refrigerating/heating, the air outlet 126 in the fresh air can be used for exhausting air, so that the fresh air flow finishes the refrigerating/heating process in the casing 10 in advance, the fresh air finally reaching the indoor is the fresh air flow with proper temperature, and the condition that the indoor environment comfort degree is influenced by directly blowing the fresh air flow when the temperature of the fresh air flow is too high or too low is avoided.
Alternatively, the first fresh air outlet 124 and the fresh air inner outlet 126 can be simultaneously used for air outlet, so that the fresh air volume is maximized.
Therefore, the air conditioner indoor unit provided by the embodiment of the invention has various fresh air supply modes, is very powerful in function and enables users to have more choices. The air conditioner can select the outflow path of fresh air according to the actual indoor air supply requirement so as to achieve the optimal fresh air effect.
As shown in fig. 1 and 2, the air conditioning indoor unit of the present invention may be a wall-mounted type, and the casing 10 thereof has a horizontally and laterally extending elongated shape. The fresh air blower 20 may be disposed at one side of the inside of the casing 10, for example, the fresh air blower 20 is disposed at the left end of the casing 10 in the scheme of the figure, so as to reduce the influence of the fresh air blower on the normal layout of the heat exchanging air inlet, the heat exchanging air outlet, the evaporator and the heat exchanging blower. In this embodiment, the air-conditioning indoor unit is described by taking a wall-mounted type as an example, and the structural form of the air-conditioning indoor unit is not limited, and the air-conditioning indoor unit may be a floor-type air-conditioning indoor unit, a ceiling-type air-conditioning indoor unit, or any other various types.
In some embodiments, as shown in fig. 4, the fresh air blower 20 further includes a damper 210 and a first motor 211. The damper 210 is pivotally mounted to the housing 100 at one end thereof with an axis of rotation between the first fresh air outlet 124 and the fresh air outlet 126 to rotate to a position closing the first fresh air outlet 124 and opening the fresh air outlet 126 (see fig. 5), or to a position closing the fresh air outlet 126 and opening the first fresh air outlet 124 (see fig. 4), or to a position opening both the first fresh air outlet 124 and the fresh air outlet 126 (not shown, at a position intermediate between fig. 4 and 5). The first motor 211 is configured to controllably drive the rotation of the damper 210.
Fig. 6 is a schematic view of the structure of the first motor cooperating with the damper.
Specifically, as shown in fig. 4 to 6, the first motor 211 may be mounted to the outside of the housing 100, and securely coupled to the housing 100 with the mounting ears 2113 thereof. The rotating shaft 2112 of the first motor 211 extends into the interior of the casing 100 through the opening of the casing 100 to be fixedly connected with the damper 210.
In some alternative embodiments, other structures may be provided to open and close the first fresh air outlet 124 and the fresh air inner outlet 126, for example, two air doors are respectively provided for the two outlets, and each air door is independently controlled to respectively control the opening and closing of the first fresh air outlet 124 and the fresh air inner outlet 126, which will not be described in detail herein.
In some embodiments, as shown in fig. 4 to 6, the housing 100 is formed with an air outlet cylinder 1011 connected to the inner space thereof, an outlet at an end of the air outlet cylinder 1011 forms a first fresh air outlet 124, and a wall of the air outlet cylinder 1011 near the end thereof forms a fresh air inner outlet 126. Thus, the first fresh air outlet 124 and the fresh air inner outlet 126 are adjacent to each other and the opening direction is vertical, and the first fresh air outlet 124 and the fresh air inner outlet 126 can be opened and closed by rotating the damper 210 within a range of approximately 90 degrees.
Further, for the wall-mounted air conditioner indoor unit, the fresh air blower 20 may be disposed adjacent to one lateral end surface (shown as the left side) of the casing 10, so that the first fresh air outlet 124 is open forward, and the first fresh air inner outlet 126 is open toward the other lateral end (right end) of the casing 100, so as to blow the fresh air flow toward the inside of the casing 10, and blow the fresh air flow toward the evaporator.
Correspondingly, the fresh air outlet 14 of the casing 10 is also opened forward, so that the fresh air outlet 14 is arranged at the upper corner of the transverse end face close to the casing 10, the height of the fresh air outlet is higher, and the air supply distance is farther after the fresh air flows out. The front fresh air outlet 14 may be formed by arranging and combining a plurality of holes, so that the casing 10 is more beautiful, and the appearance of the casing 10 is prevented from being affected by a large opening.
As shown in fig. 1 to 3, an upper fresh air outlet 13 may be formed on the top surface of the casing 10, and a lower fresh air outlet 15 may be formed on the bottom surface of the casing 10. Correspondingly, the fresh air fan 20 is provided with upward and downward fresh air outlets 123, 125 to be connected with the upper fresh air outlet 13 and the lower fresh air outlet 15, respectively. Set up the new trend air outlet through the different surfaces at casing 10 for the new trend air current blows off towards the different directions, updates the air current in different regions simultaneously, accelerates indoor air update rate, makes the user fully feel the existence of new trend. In addition, more fresh air outlets can be arranged on the casing 100.
Because a plurality of new trend exports the air-out simultaneously for new trend fan 20's air-out is more smooth and easy, and wind-force is stronger. Moreover, the quantity of the fresh air outlets is increased, and the air outlet resistance of each fresh air outlet is reduced. Under the same air quantity, the rotating speed of the fresh air fan 20 is reduced by increasing the fresh air outlet, so that the power consumption and the noise are lower.
Fig. 7 is an exploded schematic view of a fresh air blower.
In some embodiments, as shown in fig. 7, the fresh air blower 20 further includes a water tank 171 whose upper side is open, a second motor 172, and a water stirring wheel 173. The water tank 171 is installed inside the casing 100, and the water stirring wheel 173 is rotated by the second motor 172, so as to stir the water in the water tank 171, thereby promoting the water to be gasified, and thus humidifying the air flow in the fresh air blower 20. The water stirring wheel 173 may include a rotating shaft 1731 connected to the second motor 172 and a plurality of blades 1732 extending from different circumferential positions of the rotating shaft 1731, and when the rotating shaft 1731 rotates, each blade 1732 stirs the water in the water tank 171 to make the water turn, so as to evaporate the water. The water tank 171 is disposed in the upstream direction, i.e., the suction side, of the impeller of the fresh air fan 20.
In some embodiments, as shown in FIG. 7, the housing 100 includes a volute 101 and a purge shell 102, which are abutted and communicate with each other in the inner space. An impeller 300 of the fresh air fan 20 is arranged in the volute 101. The first fresh air outlet 124, the upper fresh air outlet 123 and the lower fresh air outlet 125 are opened on the scroll casing 101. The purifying shell 102 is provided with a fresh air inlet 110, and a purifying module 200 is arranged in the fresh air inlet 110, so that fresh air sucked from the fresh air inlet 110 can flow to the impeller 300 after passing through the purifying module 200 and being purified by the same. The purification module 200 may be a filtration module to filter out harmful impurities in the fresh air stream. The purification module 200 may also have other processing functions to further process the fresh air stream to make it more fresh and healthy.
As shown in fig. 1 to 7, the volute 101 and the purifying casing 102 can be flat and connected in parallel with each other in the thickness direction, and the two can be fastened by screws. The impeller 300 may be a centrifugal impeller, and one end of the thickness direction (x-axis direction) of the scroll casing 101 facing the purification casing 102 is provided with a suction port 1012. The side of the purification case 102 facing the scroll 101 is opened so as to cover the scroll 101, and the edges are sealed and connected, and the inner space is communicated. The decontamination module 200 is enclosed by the decontamination housing 102. Under the rotation of the impeller 300, the fresh air flow enters the cleaning housing 102 from the fresh air inlet 110 of the cleaning housing 102, flows through the cleaning module 200 to be cleaned, and then enters the volute 101 from the suction port 1012. Under the action of the impeller 300, the purified air flow is radially thrown out along the impeller 300, and then is discharged out of the volute 101 through the first fresh air outlet 124, the upper fresh air outlet 123 and the lower fresh air outlet 125. Of course, the impeller 300 may be an axial-flow impeller or other type of impeller, and detailed description thereof is omitted here.
In some embodiments, as shown in fig. 1-7, the peripheral surface of the purification shell 102 is provided with a socket 140 to allow the purification module 200 to be inserted into the purification shell 102 through the socket 140 to facilitate installation, cleaning and replacement of the purification module 200.
FIG. 8 is a schematic view of the purification case in a state where the fresh air inlet is opened by rotating the shutter; fig. 9 is a schematic view of the state of the purification case when the return air opening is opened by rotating the shutter.
In some embodiments, as shown in fig. 8 and 9, the casing 100 further defines a return air opening 150 facing the inside of the casing 10 for sucking in a non-fresh air flow, in particular so as to open onto the purification casing 102. In one aspect, the air return opening 150 is located at the bottom of the casing 100 and is open downward to draw the heat exchange air flow inside the cabinet 10. In another solution, not shown, the air return opening may be directed to the heat exchanging air inlet 11 of the casing 10 to suck the room air without heat exchange.
The fresh air blower 20 is configured to allow the fresh air inlet 110 and the return air inlet 150 to be opened simultaneously or alternatively. When the indoor unit of the air conditioner operates in the fresh air mode, the fresh air inlet 110 is opened, the return air inlet 150 is closed, and all the air entering the fresh air fan 20 is fresh air, as shown in fig. 8. When there is no fresh air demand indoors, the fresh air inlet 110 is closed, and the return air inlet 150 is opened, so that the fresh air blower 20 undertakes the blowing work of the heat exchange air flow to accelerate the indoor cooling/heating speed, as shown in fig. 9. Of course, the fresh air inlet 110 and the return air inlet 150 can also be opened simultaneously, so that the fresh air flow and the heat exchange air flow are mixed in the fresh air blower 20 and then blown out. The mixing process of the fresh air and other air flows is completed in advance, and the updating speed of the indoor air is accelerated.
In a word, the setting of return air inlet 150 has greatly enriched the function of new trend fan 20, and the design is very ingenious.
As shown in fig. 8 and 9, in some embodiments, the fresh air inlet 110 and the return air inlet 150 are adjacent. The fresh air blower 20 further includes a rotary damper 190 and a third motor 180. One end of the rotating baffle 190 can be pivotally installed between the fresh air inlet 110 and the air return opening 150 to rotate to the position of closing the fresh air inlet 110 and opening the air return opening 150, as shown in fig. 9; or rotated to a position closing the return air opening 150 and opening the fresh air inlet 110, as shown in fig. 8. The third motor 180 is configured to controllably drive the rotation of the rotary damper 190. It will be appreciated that when the rotary damper 190 is rotated to the intermediate state of fig. 8 and 9, both the fresh air inlet 110 and the return air inlet 150 are opened. This embodiment can control the fresh air inlet 110 and the return air inlet 150 only by providing a rotary damper 190 and a third motor 180, and the structure is very simple and practical.
In some alternative embodiments, the translational baffle may also be used to control the opening and closing of the fresh air inlet 110 and the air return opening 150, and two third motors and two baffles may also be provided to control the opening and closing of the fresh air inlet 110 and the air return opening 150, which is not described in detail again.
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.
