Description

Technical Field

[0001] This utility model relates to the field of air conditioning technology, and in particular to an indoor unit of an air conditioner. Background Technology

[0002] Some cabinet-type air conditioner indoor units include a first transmission box, a first drive motor located on the upper side of the first transmission box, a second transmission box, a second drive motor located on the lower side of the second transmission box, and a first and a second sliding plate located at two horizontal air outlets. The first transmission box is connected to the upper part of the first sliding plate, and the second transmission box is connected to the lower part of the second sliding plate. Each transmission box includes sheet metal extending out and connecting to the sliding plate. The sheet metal includes an upward-facing flange. The inner sidewalls of the first and second sliding plates are respectively provided with downward-facing mounting holes. The flange is inserted into the mounting holes to connect the first transmission box to the first sliding plate and the second transmission box to the second sliding plate. The sheet metal on both the first and second transmission boxes can be slidably mounted to drive the corresponding sliding plate to slide at the corresponding air outlet to open and close the air outlet. When the first transmission box is moved to the mounting position of the second transmission box, in order to ensure that the drive motor is located on the lower side of the transmission box, the first transmission box can only be reversed, and the flange of the sheet metal is facing downwards, making it impossible to install at the mounting position of the second transmission box, thus making the first and second transmission boxes non-interchangeable. This situation increases the variety of parts in the air conditioner indoor unit and increases production costs. Utility Model Content

[0042] Figure 2 This is a schematic structural diagram illustrating the installation of a drive device according to an embodiment of the present invention, as shown below. Figure 2 As shown, and refer to Figures 2 to 6 This utility model provides an indoor unit for an air conditioner, including a housing 100, a first sliding plate 200, a second sliding plate 800, and two first driving devices 400. The housing 100 has a first air outlet and a second air outlet. The first sliding plate 200 is slidably disposed at the first air outlet and configured to open or close the first air outlet. A first insert 300 for downward insertion is provided on the first sliding plate 200. The second sliding plate is slidably disposed at the second air outlet and configured to open or close the second air outlet. A second insert for downward insertion is provided on the second sliding plate. The output portion of each first driving device 400 has a first through hole 410, which has a first side and a second side disposed opposite to each other. The first side of the first through hole 410 of one first driving device 400 faces upward, and the second side of the first through hole 410 of the other first driving device 400 faces upward. The first insert 300 is inserted into the first through hole 410 of one first driving device 400 from the upper side of the first through hole 410. The second insert is inserted into the first perforation 410 from the upper side of the first drive device 400.

[0043] The first insert 300 on the first slide plate 200 is inserted into the first through hole 410 of the first drive device 400 from the upper side, thus enabling the installation of the first slide plate 200 with one first drive device 400. Another first drive device 400 is mounted on the second slide plate in reverse order. The second insert on the second slide plate is inserted into the first through hole 410 of the other first drive device 400 from the upper side, thus enabling the second slide plate to be mounted in reverse order with the other first drive device 400. The first drive device 400 can be mounted both with the first slide plate 200 and vice versa, solving the problem of... Figure 1 In the prior art shown, the presence of the upward-curved edge 430 of the sheet metal causes a problem of incompatibility between the first drive device and the first and second slide plates. The above-described design optimizes the connection structure between the first drive device and the first and second slide plates, greatly improving the versatility of the first drive device and the convenience of slide plate installation.

[0044] In some embodiments of this utility model, such as Figure 5 As shown, the indoor unit of the air conditioner also includes two second drive units 500. The output portion of each second drive unit 500 has a second through hole 510, which has a third side and a fourth side disposed opposite to each other. The third side of the second through hole 510 of one second drive unit 500 faces upwards, and the fourth side of the second through hole 510 of the other second drive unit 500 faces upwards. A third insert 600 for downward insertion is also provided on the first slide plate 200. A fourth insert for downward insertion is also provided on the second slide plate. The third insert 600 is inserted into the second through hole 510 of one second drive unit 500 from the upper side. The fourth insert is inserted into the second through hole 510 of the other second drive unit 500 from the upper side.

[0045] A third insert 600 is inserted into the second through hole 510 of a second drive device 500 from the upper side, thereby enabling the installation of the first slide plate 200 with one second drive device 500. The other second drive device 500 is installed in reverse order, and a fourth insert is inserted into the second through hole 510 of the other second drive device 500 from the upper side, enabling the second slide plate to be installed in reverse order with the other second drive device 500. The second drive device 500 can be installed with both the first slide plate 200 and, conversely, with the second slide plate, thus solving the problem in the prior art where the presence of the upward-curved edge 430 of the sheet metal prevents the second drive device from being universally compatible.

[0046] In some embodiments of this utility model, such as Figure 2 As shown, the first drive device 400 and the second drive device 500 are symmetrical in structure.

[0047] In some embodiments of this utility model, such as Figure 6 As shown, the first slide plate 200 and the second slide plate 800 are symmetrically arranged. The first insert 300 and the fourth insert are symmetrically arranged. The third insert 600 and the second insert are symmetrically arranged. The symmetrically arranged first slide plate 200 and second slide plate are used to open and close corresponding air outlets. The first insert 300 is inserted into the first through hole 410 to mount the first drive device 400 on the first slide plate 200, and the third insert is inserted into the second through hole to mount the second drive device 500 on the first slide plate. The second insert is inserted into the first through hole to mount the first drive device on the second slide plate, and the fourth insert is inserted into the second through hole 510 to mount the second drive device 500 on the second slide plate. For example, two first drive devices 400 can be mounted on the upper part of the first slide plate 200 and the lower part of the second slide plate, and two second drive devices 500 can be mounted on the upper part of the second slide plate and the lower part of the first slide plate 200.

[0048] In some embodiments of this invention, both the first drive device 400 and the second drive device 500 are provided with installation position markings. These markings help prevent mistaken identification and also allow operators to more intuitively locate the installation position.

[0049] In some embodiments of this utility model, such as Figure 4 As shown, at least two first inserts 300 and at least two second inserts are provided, with at least two first inserts 300 at the same height and at least two second inserts at the same height. At least two first through holes 410 are provided in the first driving device 400, and these at least two first through holes 410 are spaced apart.

[0050] The first insert 300 and the second insert are both configured as at least two, which prevents relative rotation between the first drive device 400 and the first slide plate 200, and between the first drive device 400 and the second slide plate. This helps to improve installation accuracy and thus ensures the movement accuracy of the first slide plate 200 and the second slide plate.

[0051] In some embodiments of this utility model, such as Figure 4 As shown, the output section of the first drive device 400 includes a mounting plate 700, and a first through hole 410 is provided on the mounting plate 700.

[0052] The mounting plate 700 has no directional restrictions, which can avoid the problem that the two first drive devices 400 cannot be used interchangeably due to the upward-facing flange 430 in the prior art.

[0053] In some embodiments of this utility model, such as Figure 5 As shown, the output section of the second drive device 500 includes a mounting plate, and a second through hole 510 is provided on the mounting plate.

[0054] The mounting plate has no directional restrictions, which avoids the problem of the two second drive devices being incompatible due to the upward-facing flange 430 in the prior art.

[0055] In some embodiments of this utility model, such as Figure 4 As shown, both the first insert 300 and the second insert include an insert plate and ribs on both sides of the insert plate. The lower ends of both the first insert 300 and the second insert are smaller than their respective upper ends.

[0056] The ribs enhance the strength of the insert plate, and the fact that the lower ends are smaller than their respective upper ends facilitates the insertion of the first insert 300 and the second insert into the corresponding first through hole 410.

[0057] In some embodiments of this utility model, such as Figure 4 and Figure 5 As shown, the third insert 600 is disposed below the first insert 300. The length of the third insert 600 is greater than the length of the first insert 300.

[0058] Taking the installation of the first slide plate 200 as an example, after the first drive device 400 and the second drive device 500 corresponding to the first slide plate 200 are installed, the first slide plate 200 is picked up at an angle. The third insert is first inserted into the second through hole 510, and then the first slide plate 200 is gradually straightened. The first slide plate is lifted upwards, and the first insert 300 is inserted into the first through hole 410, thus realizing the installation of the first slide plate 200 with the corresponding first drive device 400 and second drive device 500. The length of the third insert 600 is greater than the length of the first insert 300 to prevent the third insert from coming out of the second through hole when the first slide plate is lifted upwards.

[0059] In some embodiments of this utility model, the first slide plate 200 is fixedly connected to the output portion of the corresponding first driving device 400 or the output portion of the corresponding second driving device. The second slide plate is fixedly connected to the output portion of the corresponding first driving device 400 or the output portion of the corresponding second driving device.

[0060] After the third insert is inserted into the second through hole 510 and the first insert 300 is inserted into the first through hole 410, thus completing the installation of the first slide plate 200 with the corresponding first drive device 400 and second drive device 500, the first slide plate 200 is fixedly connected to the output part of the corresponding first drive device 400. At this time, the third insert can move within the second through hole 510. In this way, if the first slide plate and the housing 100 deform inconsistently in the length direction due to thermal expansion and contraction, this inconsistency can be compensated by the movement of the third insert within the second through hole 510. The installation process of the second slide plate is the same as that of the first slide plate 200.

[0061] In some embodiments of this utility model, such as Figure 4 and Figure 5 As shown, the first drive device 400 includes a first drive motor 420. The second drive device 500 includes a second drive motor 520.

[0062] In some embodiments of this utility model, such as Figure 6 As shown, a first air outlet 101 is disposed on one side wall of the housing 100, and a second air outlet 102 is disposed on the other side wall of the housing 100. Both the first air outlet 101 and the second air outlet 102 extend vertically. An air duct is disposed inside the housing 100, the air duct having a main air duct section 130, and a first air duct section 110 and a second air duct section 120 connected to the front end of the main air duct section 130. The first air duct section 110 is connected to the first air outlet 101, and the second air duct section 120 is connected to the second air outlet 102. The main air duct section 130 includes a first air duct wall 131 and a second air duct wall 132 disposed opposite to each other. A cross-flow impeller 140 is disposed inside the housing 100. The first air duct wall 131 is a volute tongue surface, and the second air duct wall 132 is a volute shell surface. The volute tongue surface has a volute tongue portion that cooperates with the cross-flow impeller 140, and the volute tongue portion, the volute shell surface, and the cross-flow impeller 140 cooperate to work together. The diversion device is located at the front end of the main air duct section 130. The diversion device is configured to guide and divert the airflow from the main air duct section 130 so that part of the airflow flows to the first air duct section 110 and the rest flows to the second air duct section 120. The diversion device includes a first diversion plate 910, a second diversion plate 920 and a third diversion plate 930 arranged at intervals.

[0063] The cross-flow fan 140 rotates, creating airflow between the volute tongue and the volute surface. This airflow passes through the first air duct section 110 and the second air duct section 120, and exits from the first air outlet 101 corresponding to the first air outlet 110 and the second air outlet 102 corresponding to the second air outlet 120. The first air outlet 101 and the second air outlet 102 are respectively located on two opposite side walls of the housing 100, increasing the air delivery range and enabling ultra-wide-angle whole-house air delivery. When the airflow generated by the cross-flow fan 140 flows between the volute tongue and the volute surface, it is mainly concentrated on one side of the volute surface. By adjusting the airflow direction through the diversion device at the front end of the main air duct section 130, the flow rate of the air entering the first air duct section 110 and the second air duct section 120 can be adjusted, and the resistance of the airflow entering the first air duct section 110 and the second air duct section 120 can be reduced. Finally, the amount of airflow flowing out of the first air outlet 101 and the second air outlet 102 is adjusted accordingly, so that the total amount of airflow flowing out of the first air outlet 101 and the second air outlet 102 is equal or not much different, so that the air outlet of the indoor unit of the air conditioner is balanced from left to right, ensuring the horizontal air supply effect, and also ensuring the uniform temperature of the indoor space.

[0064] In some embodiments of this utility model, such as Figure 6 As shown, the first air duct section 110 is connected to the first air duct wall 131, and the second air duct section 120 is connected to the second air duct wall 132. The second air duct wall 132 is configured such that the airflow direction within the main air duct section 130 is towards the side of the housing 100 with the first air outlet 101. The angle of change of the airflow direction from the main air duct section 130 under the action of the second air duct section 120 is greater than the angle of change under the action of the first air duct section 110.

[0065] The tangent at the front end of the volute surface of the second air duct wall 132 faces the first air duct section 110, causing the airflow on one side of the volute surface to flow towards the inlet of the first air duct under the guidance of the volute surface. Therefore, the second air duct wall 132 is configured such that the flow direction of the airflow in the main air duct section 130 faces the side of the housing 100 with the first air outlet 101. Here, the angle at which the flow direction of the airflow in the main air duct section 130 changes under the action of the second air duct section 120 is greater than the angle at which it changes under the action of the first air duct section 110. This means that the forward angle between the flow direction of the airflow in the main air duct section 130 and the flow direction of the airflow in the second air duct section 120 is greater than the forward angle between the flow direction of the airflow in the main air duct section 130 and the flow direction of the airflow in the first air duct section 110. This arrangement increases the resistance of the airflow entering the second air duct section 120. Therefore, without the guidance of the diversion device, the amount of airflow passing through the first air duct will be much greater than the amount of airflow passing through the second air duct.

[0066] Therefore, those skilled in the art should recognize that although many exemplary embodiments of the present invention have been shown and described in detail herein, many other variations or modifications conforming to the principles of the present invention can be directly determined or derived from the disclosure of the present invention without departing from the spirit and scope of the present invention. Therefore, the scope of the present invention should be understood and recognized as covering all such other variations or modifications.
