Description

Technical Field

[0001] The present invention relates to the technical field of air conditioning, and in particular to a wall-mounted air conditioning indoor unit. Background Art

[0002] A cross-flow fan is installed in the indoor unit of a wall-mounted air conditioner. When the air conditioner has been running for a long time, a lot of dust will accumulate on the blades of the cross-flow fan, which will increase the wind resistance, reduce the wind force, and easily breed bacteria, producing mold and odor. Some dust on the surface of the blades will also be blown into the room, affecting the indoor air quality.

[0003] However, in the prior art, when a user wants to clean the fan, he needs to disassemble the wall-mounted air conditioner indoor unit as a whole and take out the cross-flow fan. This process is cumbersome and time-consuming and generally requires the operation of professionals. Summary of the invention

[0004] An object of the present invention is to provide a wall-mounted air conditioner indoor unit capable of cleaning a cross-flow fan.

[0005] Another object of the present invention is to reduce the interference of the cleaning device with the air supply air flow.

[0006] In particular, the present invention provides a wall-mounted air conditioner indoor unit, comprising:

[0007] A housing, which defines a cross-flow air duct, wherein an air duct wall of the cross-flow air duct has an opening;

[0008] a crossflow fan, disposed in the crossflow air duct; and

[0009] A cleaning device, comprising a windshield and a cleaning unit, wherein the windshield is used to open and close the opening, and the cleaning unit is mounted on the windshield;

[0010] When the wind shield is in a closed state, the cleaning part is away from the cross flow blower; when the wind shield moves to an open state, the cleaning part moves with the wind shield to a position close to the cross flow blower so as to clean the cross flow blower.

[0011] Optionally, the air duct walls defining the cross-flow air duct include a front air duct wall, a rear air duct wall and two transverse end walls which are spaced apart from each other in the front and rear directions, and the opening is formed in the rear air duct wall.

[0012] Optionally, the cleaning unit is used to clean, spray air and / or water the cross-flow blower.

[0013] Optionally, the cleaning unit is movably mounted on the wind shield plate to clean the crossflow fan; and

[0014] The cleaning device also includes a driving mechanism configured to: during the process of driving the windshield from the closed state to the open state, simultaneously drive the cleaning part from a folded state stored in the windshield to an unfolded state in contact with the cross-flow blower, so as to clean the cross-flow blower.

[0015] Optionally, when the cleaning portion is in the folded state, it abuts against a surface of the wind shield plate that faces the inside of the cross-flow air duct when the wind shield plate is in the closed state.

[0016] Optionally, the driving mechanism is further configured to: during the process of driving the windshield from the open state to the closed state, simultaneously drive the cleaning portion from the unfolded state to the folded state.

[0017] Optionally, the driving mechanism comprises a gear mechanism, and a first gear of the gear mechanism is fixed to the windshield;

[0018] The cleaning part is provided with an intermittent motion gear;

[0019] In the later stage of the process in which the gear mechanism drives the windshield plate to rotate from the closed state to the open state, the intermittent motion gear begins to mesh with the second gear of the gear mechanism and is driven to rotate thereby, so as to drive the cleaning part to rotate to the unfolded state;

[0020] In the early stage of the process in which the gear mechanism drives the windshield to rotate from the open state to the closed state, the intermittent motion gear is driven by the second gear to rotate so that the cleaning part rotates to the folded state, and then the intermittent motion gear disengages from the second gear so that the cleaning part remains in the folded state and continues to rotate with the windshield.

[0021] Optionally, the air duct walls defining the crossflow air duct include a front air duct wall, a rear air duct wall and two transverse end walls arranged in a front-to-rear interval;

[0022] The driving mechanism is arranged on the outer side of one of the transverse end walls, and the transverse end wall is provided with an arc-shaped hole to allow the rotating shaft of the cleaning part to extend out from the cross-flow air duct;

[0023] The gear mechanism further comprises:

[0024] a third gear rotatably mounted on the transverse end wall and meshing with the first gear;

[0025] a fourth gear, rotatably mounted on the transverse end wall and meshing with the third gear;

[0026] The second gear and the fourth gear are fixed to the same shaft and are closer to the transverse end wall.

[0027] Optionally, the cleaning portion is in the shape of a long strip extending along the axial direction of the cross-flow fan, so that when the cleaning portion is in the expanded state and the cross-flow fan rotates, the cleaning portion and the surface of the cross-flow fan rub against each other to achieve a cleaning function.

[0028] Optionally, the cleaning part includes a plate body connected to the wind shield and bristles installed on one side edge of the plate body.

[0029] The wall-mounted air conditioner indoor unit of the present invention has a cleaning device, which includes a windshield and a cleaning part. When the wall-mounted air conditioner indoor unit is in normal operation, the windshield closes the opening of the air duct wall, which is equivalent to a component of the air duct wall, does not interfere with the normal flow of the airflow, and is also convenient for the operator to disassemble and clean the cleaning part from the rear side of the wall-mounted air conditioner indoor unit. Moreover, the cleaning part is also far away from the cross-flow fan at this time, and has little or no interference with the airflow in the cross-flow air duct. When the cross-flow fan needs to be cleaned, the windshield is moved to an open state to prompt the cleaning part to approach the cross-flow fan for cleaning.

[0030] Furthermore, the wall-mounted air conditioner indoor unit of the present invention has a driving mechanism that can drive the windshield plate and the cleaning unit to move at the same time. When the crossflow fan needs to be cleaned, the driving mechanism is controlled to move so that the windshield plate is driven to turn to the open state and the windshield plate is driven to rotate to the unfolded state so that the surface of the crossflow fan can be cleaned. The driving mechanism can drive the windshield plate and the cleaning unit to move at the same time, and there is no need to design an additional driving structure for the cleaning unit, which makes the structure of the wall-mounted air conditioner indoor unit simpler.

[0031] Furthermore, in the wall-mounted air conditioner indoor unit of the present invention, the driving mechanism includes a gear mechanism, and an intermittent motion gear is provided on the cleaning part. In the early stage when the gear mechanism drives the windshield to rotate to the open state, the intermittent motion gear is free from the gear mechanism. When the windshield rotates to the later stage of the open state, the intermittent motion gear is meshed with the second gear of the gear mechanism, so that the intermittent motion gear rotates at a small angle, so as to just rotate from the folded state to the unfolded state. This design is very clever.

[0046] Figure 1 is a schematic structural diagram of a wall-mounted air conditioner indoor unit according to an embodiment of the present invention; Figure 2 yes Figure 1 A schematic diagram of a rear side view of a wall-mounted air conditioner indoor unit is shown; Figure 3 yes Figure 1 A schematic structural diagram of the skeleton of the indoor unit of the wall-mounted air conditioner shown; Figure 4 It is cut along a vertical plane extending forward and backward Figure 1 A cross-sectional enlarged view of a wall-mounted air conditioner indoor unit; Figure 5 yes Figure 4 The schematic diagram of the indoor unit of the wall-mounted air conditioner shown is when being cleaned by a cleaning device.

[0047] The embodiment of the present invention provides a wall-mounted air conditioner indoor unit. The wall-mounted air conditioner indoor unit is the indoor part of a split wall-mounted room air conditioner, and is used to regulate indoor air, such as cooling / heating, dehumidifying, humidifying, purifying, introducing fresh air, etc.

[0048] like Figures 1 to 5 As shown, the wall-mounted air conditioner indoor unit according to the embodiment of the present invention may generally include a casing 10 , a cross-flow fan 40 and a cleaning device 20 .

[0049] The housing 10 defines a cross-flow duct 150. The cross-flow fan 40 is disposed in the cross-flow duct 150. The cross-flow duct 150 has an air outlet 12. The cross-flow fan 40 is used to force the conditioned airflow in the cross-flow duct 150 to blow to the outside of the housing 10 through the air outlet 12.

[0050] For example Figure 1 and Figure 3 As shown, the housing 10 may include a frame 15 for defining a cross-flow air duct 150 and a panel 16 wrapped around the outside of the frame 15 for sealing and decoration.

[0051] Specifically, the housing 10 defines a storage space for accommodating the main components of the indoor unit of the wall-mounted air conditioner, in which an indoor heat exchanger 30 is arranged. The indoor heat exchanger 30 is connected to the throttling device, the compressor arranged in the outdoor unit, the outdoor heat exchanger and other refrigeration elements through pipelines to form a vapor compression refrigeration cycle system. Under the action of the cross-flow fan 40, the indoor air enters the housing 10 through the air inlet 11 of the housing 10, and forms a heat exchange airflow after completing the heat exchange with the indoor heat exchanger 30. The heat exchange airflow enters the cross-flow air duct 150, is guided by the cross-flow air duct 150, and finally reaches the air outlet 12 to blow toward the indoor environment to complete the adjustment of the indoor environment. The air outlet 12 can be provided with air guide components such as an air guide plate 50 and a swing blade to adjust the air outlet direction of the air outlet 12.

[0052] The cross-flow air duct 150 is defined by a plurality of air duct walls (solid plate-shaped walls), and at least one air duct wall (such as the rear air duct wall 151) of the cross-flow air duct 150 has an opening 1513. Figure 5 The opening 1513 allows the inner and outer spaces of the cross-flow air duct 150 to communicate with each other.

[0053] The cleaning device 20 includes a windshield 100 and a cleaning unit 200. The windshield 100 is used to open and close the opening 1513. The number of windshields 100 can be one or multiple windshields 100 arranged side by side. For example, the windshield 100 can be rotatably mounted on the wall of the air duct. The cleaning unit 200 is mounted on the windshield 100. When the windshield 100 is in a closed state (i.e., the opening 1513 is closed), the cleaning unit 200 is away from the crossflow blower 40, such as Figure 4 When the windshield 100 moves to the open state (ie, the state of opening 1513), the cleaning unit 200 moves with the windshield 100 to a position close to the crossflow fan 40 so as to clean the crossflow fan 40, such as Figure 5 .

[0054] The cleaning part 200 is used to clean, spray air and / or water the crossflow fan 40. In the following specific embodiments, the cleaning part 200 with a cleaning function will be described as an example. Specifically, the cleaning part 200 can be a long strip extending along the axial direction (X direction) of the crossflow fan 40, such as Figure 3, so that when the cross flow fan 40 is in the unfolded state and rotates, the cleaning part 200 and the surface of the cross flow fan 40 rub against each other to achieve the cleaning function. The dust dropped by cleaning can flow along the inner wall of the cross flow duct 150 to the air outlet 12, and the user can then clean it.

[0055] In some embodiments, Figure 3 and Figure 4 As shown, the duct wall defining the cross-flow duct 150 includes a front duct wall 152, a rear duct wall 151, and two transverse end walls 153 and 154 that are spaced apart from each other. In the figure, X represents the transverse direction, which is the length direction of the wall-mounted air conditioner indoor unit, the cross-flow fan 40, and the cross-flow duct 150, and is also the direction of the rotation axis of the wind shield 100 and the cleaning unit 200. Since the space near the rear duct wall 151 is relatively open, the opening 1513 can be opened in the rear duct wall 151. Furthermore, the cleaning unit 200, when in the folded state, is abutted against the surface of the wind shield 100 that faces the inside of the cross-flow duct 150 when it is in the closed state.

[0056] When the wall-mounted air conditioner indoor unit is in normal operation, the wind shield 100 closes the opening 1513 of the air duct wall, which is equivalent to a component of the air duct wall, does not interfere with the normal flow of the airflow, and is also convenient for the operator to disassemble and clean the cleaning part from the rear side of the wall-mounted air conditioner indoor unit. Moreover, at this time, the cleaning part 200 is also far away from the cross-flow fan 40, and has little or no interference with the airflow in the cross-flow air duct 150. When the cross-flow fan 40 needs to be cleaned, the wind shield 100 is moved to the open state to facilitate the cleaning part 200 to approach the cross-flow fan 40 for cleaning.

[0057] In some embodiments, Figure 4 and Figure 5 As shown, the cleaning unit 200 can be movably mounted on the wind shield 100 for cleaning the cross flow fan 40. For example, the cleaning unit 200 can be rotatably mounted on the wind shield 100. The driving mechanism 300 is configured to: when the wind shield 100 is moved from a closed state away from the cross flow fan 40 (such as Figure 4 ) is driven to make the cleaning section 200 close to the open state of the cross flow fan 40 (such as Figure 5 ), the cleaning unit 200 is simultaneously driven from the folded state stored in the windshield 100 to the unfolded state contacting the crossflow fan 40, so as to clean the crossflow fan 40. Further, the driving mechanism 300 can also be configured to: when the windshield 100 is moved from the open state (such as Figure 5 ) is driven to the closed state (such as Figure 4 ), the cleaning unit 200 is simultaneously driven from the unfolded state to the folded state.

[0058] When the crossflow fan 40 needs to be cleaned, the driving mechanism 300 is controlled to operate, so that the wind shield 100 is driven to turn to the open state and the wind shield 100 is driven to rotate to the unfolded state, so that the surface of the crossflow fan 40 can be cleaned. The driving mechanism 300 can drive the wind shield 100 and the cleaning unit 200 to operate at the same time, and there is no need to design an additional driving structure for the cleaning unit 200, so that the structure of the wall-mounted air conditioner indoor unit is simpler.

[0059] Figure 6 yes Figure 3 Enlarged view of point A.

[0060] In some embodiments, please refer to Figure 6 , the cleaning part 200 may include a plate body 201 connected to the windshield 100 and bristles 205 installed on one side edge of the plate body 201. In the unfolded state, although the cleaning part 200 does not move, the cross flow fan 40 rotates, so that the two rotate relative to each other, so that the bristles 205 can still sweep the dust on the surface of the cross flow fan 40.

[0061] Figure 7 yes Figure 3 Another perspective schematic diagram of the skeleton 15 is shown; Figure 8 yes Figure 7 A magnified view of point B;

[0062] Fig. 9 yes Figure 8 The structure shown is a schematic diagram of the state after the intermittent motion gear 350 is meshed with the second gear 320.

[0063] In some embodiments, please refer to Figure 8 and Fig. 9 The driving mechanism 300 includes a gear mechanism, and the first gear 310 of the gear mechanism is fixed to the windshield 100. Specifically, the first gear 310 is fixed to the rotating shaft 110 of the windshield 100. The cleaning unit 200 is provided with an intermittent gear 350. In the early stage of the gear mechanism driving the windshield 100 to rotate from the closed state to the open state, the intermittent gear 350 is not meshed with the gears of the gear mechanism. Figure 8 In the later stage of the gear mechanism driving the windshield plate 100 to rotate from the closed state to the open state, the intermittent motion gear 350 begins to mesh with the second gear 320 of the gear mechanism and is driven to rotate thereby driving the cleaning part 200 to rotate to the unfolded state. Fig. 9 It can be seen that the movement of the intermittent motion gear 350 is intermittent. Of course, this requires that the central axis of the intermittent motion gear 350 is colinear with the rotating shaft 351 of the cleaning unit 200 and the intermittent motion gear 350 is fixed to the cleaning unit 200.

[0064] Similarly, in the early stage of the process in which the gear mechanism drives the windshield 100 to rotate from the open state to the closed state, the intermittent motion gear 350 is driven by the second gear 320 to rotate so that the cleaning part 200 is rotated to the folded state, and then the intermittent motion gear 350 is disengaged from the second gear 320, so that the cleaning part 200 remains in the folded state and continues to rotate with the windshield 100 until the windshield 100 is rotated to the closed state.

[0065] In the above embodiment of the present invention, in the early stage when the gear mechanism drives the windshield 100 to rotate toward the open state, the intermittent motion gear 350 is free from the gear mechanism. When the windshield 100 rotates to the late stage of the open state, the intermittent motion gear 350 is meshed with the second gear 320 of the gear mechanism, so that the intermittent motion gear 350 rotates at a small angle, so as to just rotate from the folded state to the unfolded state. This design is very clever.

[0066] In some embodiments, Figure 6 and Figure 8 As shown, the driving mechanism 300 can be disposed outside a transverse end wall 153, and the transverse end wall 153 is provided with an arc-shaped hole 1533 to allow the rotating shaft 351 of the cleaning portion 200 to extend from the cross-flow air duct 150. In this way, the driving mechanism 300 is located outside the cross-flow air duct 150 and will not interfere with the normal flow of the airflow in the cross-flow air duct 150.

[0067] Furthermore, if Figure 8 As shown, the gear mechanism may further include a third gear 330 and a fourth gear 340. The third gear 330 is rotatably mounted on the transverse end wall 153 and meshed with the first gear 310. Specifically, the third gear 330 may be rotatably disposed on a rotating shaft 331, and the rotating shaft 331 is fixed to the transverse end wall 153. The fourth gear 340 is rotatably mounted on the transverse end wall 153 and meshed with the third gear 330. The second gear 320 and the fourth gear 340 are fixed to the same shaft 341. The shaft 341 is rotatably mounted on the transverse end wall 153. The second gear 320 is closer to the transverse end wall 153 than the fourth gear 340, so as to be fixedly connected to the rotating shaft 351 of the cleaning portion 200.

[0068] Thus, the rotation direction of the intermittent gear 350 is opposite to that of the first gear 310 , so that the cleaning unit 200 and the windshield 100 rotate in opposite directions, so that when the windshield 100 rotates toward the open state, the cleaning unit 200 rotates toward the unfolded state.

[0069] Furthermore, if Figure 8As shown, since the torque required for the windshield 100 to rotate is larger and the torque required for the cleaning unit 200 is smaller, the motor 360 of the driving mechanism 300 can directly drive the windshield 100 to better drive the windshield 100 to rotate and avoid being stuck. The motor 360 drives the first gear 310 to rotate, the first gear 310 drives the third gear 330 to rotate, the third gear 330 drives the fourth gear 340 to rotate, the fourth gear 340 drives the shaft 341 to rotate, and the shaft 341 drives the second gear 320 to rotate.

[0070] In some embodiments, the windshield 100 can be rotatably mounted on the rear air duct wall 151, and the cleaning unit 200 is connected to the lower end of the windshield 100 (the direction is based on the closed state). For the crossflow blower 40, the size of its rear air duct wall 151 is larger, and there is enough space to place the windshield 100, so it is installed on the rear air duct wall 151. Of course, in some alternative embodiments, the windshield 100 can also be installed on the front air duct wall 152.

[0071] At this point, those skilled in the art should recognize that, although multiple exemplary embodiments of the present invention have been shown and described in detail herein, many other variations or modifications that conform to the principles of the present invention can still be directly determined or derived based on the content disclosed in 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 these other variations or modifications.
