FIG. 1 discloses a perspective view of a fan coil 100 according to one embodiment of the present application; FIG. 2 discloses a perspective view of the fan coil 100 of FIG. 1 with the air outlet panel 2 removed; fig. 3 discloses a partially exploded view of a fan coil 100 in accordance with one embodiment of the present application. As shown in fig. 1 to 3, a fan coil 100 according to an embodiment of the present application includes a main body 1 and an air outlet panel 2 installed at an air outlet of the main body 1. A fan (not shown) and a heat exchanger 12 (shown in fig. 7 and 8) are included in the main body 1.

The application also provides a cleaning device 3 for a fan coil 100. The cleaning device 3 is located between the main body 1 and the air outlet panel 2.

As shown in fig. 2 and 3, in one embodiment, the cleaning device 3 of the present application may be mounted on the housing of the main body 1. In another embodiment, as shown in fig. 4, the cleaning device 3 of the present application may also be mounted on the air outlet panel 2.

Referring to fig. 3, the cleaning apparatus 3 according to an embodiment of the present application may include a shower assembly 31, a transmission 32 (shown in fig. 4), and a driving device 33. The spray assembly 31 may be used to spray liquid onto the heat exchanger 12 of the fan coil 100 to clean the heat exchanger 12.

As shown in fig. 2 and 3, in the embodiment in which the cleaning apparatus 3 of the present application is mounted on the housing of the main body 1, the shower assemblies 31 may be rotatably mounted on the respective both sidewalls of the housing of the main body 1 by two bearings 35, respectively. In the embodiment of the cleaning device 3 according to the present application mounted on the air outlet panel 2, as shown in fig. 4, the shower assemblies 31 may be rotatably mounted on the corresponding two sidewalls of the air outlet panel 2 through two bearings 35, respectively.

The spray assembly 31 is connected to a drive 33 by a transmission 32. Wherein the driving device 33 can drive and control the spray assembly 31 to rotate within a preset angle range through the transmission device 32, so that the spraying direction of the spray assembly 31 can be changed.

The cleaning device 3 can realize automatic cleaning of the heat exchanger 12 in the fan coil 100, and when the heat exchanger 12 is cleaned, the air outlet panel 2 of the fan coil 100 does not need to be disassembled, and the whole cleaning process is simple and convenient.

Fig. 5 discloses a partial side view of a spray assembly 31 in accordance with one embodiment of the present application. As shown in fig. 3 and 5, in some embodiments, the spray assembly 31 of the present application includes a spray tube 311. A plurality of spray holes 312 for spraying out liquid are formed in the pipe wall of the spray pipe 311.

The driving device 33 may drive the shower pipe 311 to rotate. In the rotating process of the spray pipe 311, the spray pipe 311 drives the spray holes 312 on the pipe wall to rotate together, so that the direction of liquid sprayed from the spray holes 312 can be changed, and further, different parts of the heat exchanger 12 can be cleaned. By changing the rotation angle range of the shower pipe 311, it is possible to ensure cleaning of the entire heat exchanger 12.

Fig. 6 discloses a cross-sectional view of the spray assembly 31 shown in fig. 5. As shown in fig. 5 and 6, alternatively, the plurality of spray holes 312 are arranged in two rows and staggered on the wall of the spray pipe 311. Therefore, the liquid can be sprayed out from the spray pipe 311 in a range of a certain angle θ when the liquid is sprayed each time, the spraying range of the spray pipe 311 when the liquid is sprayed each time can be enlarged, and further, the larger area of the heat exchanger 12 can be cleaned at one time.

In other embodiments, the spray assembly 31 of the present application may include a spray pipe 311 and a plurality of spray heads (not shown) disposed on the spray pipe 311 for spraying out the liquid.

The spray head may be fixed to the shower pipe 311. The driving device 33 can drive the spray pipe 311 to rotate, and the rotation of the spray pipe 311 can drive the spray heads to rotate together. Thus, the direction of the liquid sprayed from the plurality of spray heads can be changed, and further, different portions of the heat exchanger 12 can be cleaned.

Of course, the spray assembly 31 of the present application is not limited to the above two configurations. Other configurations of the spray assembly 31 of the present application are also contemplated. For example, in other embodiments, the spray assembly 31 of the present application may be implemented using a spray tube 311 with a plurality of spray heads rotatably mounted to the spray tube 311. The shower pipe 311 itself may not rotate. Thus, in use, the shower pipe 311 remains stationary and the plurality of spray heads on the shower pipe 311 are controlled to rotate. Further, the spray angles of the plurality of spray heads may be controlled to rotate in the same direction or in different directions. The above-described structural forms of the spray assembly 31 are listed only as some examples of the present application and are not intended to be limiting of the spray assembly 31 of the present application. It is contemplated that any structural design that enables the spray assembly 31 to rotate within a predetermined angular range to change the direction of the spray assembly 31 will be within the scope of the present application.

The spray pipe 311 is disposed along a first direction of the surface of the heat exchanger 12, and the driving device 33 is used to drive the spray pipe 311 to rotate around the first direction, so that the spray direction of the spray pipe 311 moves in a second direction of the surface of the heat exchanger 12, wherein the first direction is perpendicular to the second direction. The first direction may be transverse or vertical to the surface of the heat exchanger 12 and the second direction may be vertical or transverse to the surface of the heat exchanger 12.

As shown in fig. 1 to 4, for example, in the illustrated embodiment of the present application, the shower pipe 311 may be disposed along a lateral direction (left-right direction) of the surface of the heat exchanger 12, and the driving device 33 may drive the shower pipe 311 to rotate around the lateral direction (left-right direction) so that the shower direction of the shower pipe 311 may be moved in a vertical direction (up-down direction) of the surface of the heat exchanger 12, i.e., the surface of the heat exchanger 12 may be shower-cleaned in the up-down direction.

Of course, the manner of disposing the shower pipe 311 of the present application is not limited to the lateral direction along the surface of the heat exchanger 12. In other embodiments, the spray pipe 311 of the present application may be disposed along a vertical direction (up-down direction) of the surface of the heat exchanger 12, and the driving device 33 may drive the spray pipe 311 to rotate around the vertical direction (up-down direction), so that the spray direction of the spray pipe 311 may move in a lateral direction (left-right direction) of the surface of the heat exchanger 12, that is, the surface of the heat exchanger 12 may be spray cleaned in the left-right direction.

However, the arrangement of the shower pipes 311 of the present application is not limited to the above, and in other embodiments of the present application, the shower pipes 311 may be arranged in the lateral and vertical directions of the surface of the heat exchanger 12, so that the surface of the heat exchanger 12 may be sprayed and cleaned from the up-down, left-right directions, respectively. For example, the cleaning device 3 of the present application may include four shower pipes 311, wherein two shower pipes 311 are arranged in the left-right direction of the surface of the heat exchanger 12 and are located at the top and bottom of the surface of the heat exchanger 12, respectively; the other two shower pipes 311 are arranged along the up-down direction of the surface of the heat exchanger 12 and are located at the left and right sides of the surface of the heat exchanger 12, respectively. Of course, a shower pipe 311 extending in the up-down direction may be disposed at the left side, the right side, or a position between the left and right sides of the surface of the heat exchanger 12, and a shower pipe 311 extending in the left-right direction may be disposed at the top, the bottom, or a position between the top and the bottom of the surface of the heat exchanger 12. Variations of these arrangements of the shower pipes 311 will fall within the scope of the cleaning device 3 of the present application.

As shown in fig. 3, in some embodiments, the cleaning device 3 of the present application may further include a control module 34. At least one end of the shower pipe 311 is connected to the control module 34. The control module 34 may include a solenoid valve (not shown), wherein whether or not the liquid is supplied to the shower pipe 311 by an external liquid supply system may be controlled by opening and closing the solenoid valve.

In the illustrated embodiment of the application, one end of the shower pipe 311 is connected to the control module 34. Accordingly, the control module 34 may control an external liquid supply system to supply liquid from one end of the shower pipe 311.

Of course, in other embodiments of the present application, the shower pipe 311 may be connected to the control module 34 at both ends. Thus, the control module 34 can control an external liquid supply system to supply liquid from both ends of the shower pipe 311.

In some alternative embodiments, the control module 34 of the present application may also include an oscillator (not shown) that may be used to atomize an externally supplied liquid.

The cleaning device 3 of the present application may have a cleaning mode and a humidifying mode. Fig. 7 discloses a schematic cross-sectional view of a cleaning device 3 according to an embodiment of the application in a cleaning mode. As shown in fig. 7, when the cleaning apparatus 3 of the present application is operated in the cleaning mode, the solenoid valve can be controlled to be opened and the oscillator to be closed, and at this time, the shower pipe 311 can spray the liquid like water. Meanwhile, the driving device 33 may control the rotation angle of the spray pipe 311 so that the liquid sprayed from the spray pipe 311 may be sprayed to the surface of the heat exchanger 12.

Fig. 8 discloses a schematic cross-sectional view of the cleaning device 3 in a humidifying mode according to an embodiment of the present application. As shown in fig. 8, when the cleaning apparatus 3 of the present application is operated in the humidification mode, both the solenoid valve and the oscillator are controlled to be opened, and at this time, after the externally supplied liquid is atomized by the oscillator, the shower pipe 311 can spray the atomized-like liquid.

In addition, when the cleaning apparatus 3 of the present application is operated in the humidification mode, the driving apparatus 33 may control and adjust the rotation angle of the spray pipe 311 such that the spray direction of the spray pipe 311 is away from the surface of the heat exchanger 12, and thus, the atomized liquid sprayed from the spray pipe 311 is not sprayed to the surface of the heat exchanger 12.

The cleaning device 3 of the present application can be flexibly switched between the cleaning mode and the humidification mode as needed.

As shown in fig. 2-4, in some embodiments, the top end of the control module 34 may be connected to a shower pipe 311 by a hose 37, and the bottom of the control module 34 is provided with a drain pipe 38 that may be used to connect to a liquid supply system. Therefore, when in use, the device only needs to be connected to an external liquid supply system, such as a water source, and the operation is very simple and convenient.

In some embodiments, the driving device 33 of the present application may include a stepping motor, so that the rotation angle of the shower pipe 311 may be more precisely controlled. The stepping motor may be fixed to a side wall of the housing of the main body 1 or a side wall of the air outlet panel 2 by a motor bracket 36.

Fig. 9 discloses a schematic view of a transmission 32 according to an embodiment of the application. As shown in fig. 9, in some embodiments, the transmission 32 of the present application may include a driving wheel 321 and a driven wheel 322 engaged with the driving wheel 321. The driving wheel 321 may be mounted on an output shaft of a driving device 33, such as a stepping motor, and the driven wheel 322 may be mounted on one end of the shower pipe 311. For example, in the illustrated embodiment of the application, the control module 34 is mounted to one end of the shower pipe 311 (i.e., the end to which the liquid is supplied), and the driven wheel 322 is mounted to the other end of the shower pipe 311 (i.e., the end to which the liquid is not supplied). Of course, the structure, the transmission method, the installation method, and the like of the transmission device 32 of the present application are not limited thereto, and in other embodiments of the present application, the transmission device 32 may be a worm gear, a chain, a belt, or the like. Variations of these configurations are intended to be within the scope of the transmission 32 of the present application.
