[0036] See also Figure 1 , Figure 1 The figure shows the overall structure of a fresh air device 100 according to one embodiment of the present invention. The figure shows a fresh air device 100 according to one embodiment of the present invention, comprising a fresh air duct 110 and a cleaning unit 120. A fresh air passage 111 is defined within the fresh air duct 110. The cleaning unit 120 has a first passage 121 connected to the fresh air duct 110. One end of the first passage 121 communicates with the fresh air passage 111, and the other end of the first passage 121 is connected to a cleaning module to allow a cleaning medium to flow into the first passage 121.

[0037] For the above-mentioned fresh air device 100, when the fresh air duct 110 needs to be cleaned after long-term use, the cleaning module introduces a cleaning medium into the first channel 121, and the cleaning medium flows into the fresh air channel 111, which can clean the fresh air duct 110, and the sewage is discharged from the fresh air duct 110. This cleaning method does not require disassembly of the fresh air duct 110, is convenient to operate, and is conducive to improving the cleaning efficiency of the fresh air duct 110, thereby ensuring the use quality of the fresh air device 100.

[0038] Optionally, the structure of the cleaning member 120 can be a tank, a tube, a trough or other structural forms. Specifically in this embodiment, the cleaning member 120 is a cleaning pipe with a tubular structure. In this way, the structure is simple and the reliability of use is strong.

[0039] Optionally, the cleaning module can be a high-pressure air pump, a water tank, tap water, a rainwater collection device, an air conditioning condenser or other cleaning structure, and the cleaning medium can be a solid, liquid or gaseous medium, such as cleaning fluid, condensed water, rainwater, compressed gas and other media.

[0040] Specifically, see Figure 1 The cleaning module is a condenser tube, and the cleaning medium is condensed water. This effectively utilizes the condensed water generated by the air conditioner to clean the fresh air duct 111. The structure is simple, no external cleaning water is required, installation is convenient, and water conservation is beneficial. This embodiment provides only one specific implementation of a cleaning module and cleaning medium, but is not intended to be limiting.

[0041] In one embodiment, see Figure 1 , the fresh air device 100 also includes a first switch component 130. The first switch component 130 is arranged in the first channel 121. When the first switch component 130 is opened, the first channel 121 is connected to the fresh air channel 111. When the first switch component 130 is closed, the first channel 121 is isolated from the fresh air channel 111. In this way, the connection and isolation between the first channel 121 and the fresh air channel 111 can be controlled by the first switch component 130. On the one hand, the cleaning medium can be temporarily stored in the first channel 121, thereby ensuring the cleaning effect during cleaning. On the other hand, the normal operation of the fresh air device 100 can be ensured. Specifically, the first switch component 130 is driven by a motor. In this way, the operation is simple and easy to use.

[0042] See also Figure 3 , Figure 3 for Figure 1Schematic diagram of the operating state of the fresh air device 100 during drainage, wherein the circle represents the cleaning medium. In one embodiment, the fresh air device 100 further includes a drain member 140. The drain member 140 is disposed on the cleaning member 120 and has a second channel 141. The second channel 141 is connected to the first channel 121, and the drain channel and the fresh air channel 111 are located on opposite sides of the first switch member 130. Thus, when the fresh air duct 110 is operating, the first switch member 130 is closed, and the cleaning medium in the first channel 121 can be drained through the drain member 140. If the cleaning medium is condensed water, the condensed water can be drained away in a timely manner.

[0043] Optionally, the structure of the drainage member 140 can be a tank, a tube, a trough or other structural forms. Specifically in this embodiment, the drainage member 140 is a drain pipe with a tubular structure. In this way, the structure is simple and the reliability is strong.

[0044] See also Figure 1 In one embodiment, the fresh air device 100 further includes a second switch 150. The second switch 150 is arranged in the second channel 141. When the second switch 150 is opened, the second channel 141 is connected to the first channel 121. When the second switch 150 is closed, the second channel 141 is blocked from the first channel 121. In this way, by controlling the opening and closing of the first switch 130 and the second switch 150, the two working modes of cleaning the fresh air duct 110 and draining condensed water can be switched, with a simple structure and high reliability. Specifically, the second switch 150 is driven by a motor. In this way, the operation is simple and easy to use.

[0045] See also Figure 1 and Figure 2 , Figure 2 Shown Figure 1 Detailed structural diagram of the tee joint 160 described in the figure, in one embodiment, the fresh air device 100 includes a tee joint 160. The tee joint 160 is provided with a transfer chamber 164, a first opening 161, a second opening 162, and a third opening 163. The first opening 161, the second opening 162, and the third opening 163 are all in communication with the transfer chamber 164. The cleaning component 120 is connected to the first opening 161 so that the first channel 121 is in communication with the transfer chamber 164 through the first opening 161. The drainage component 140 is connected to the second opening 162 so that the second channel 141 is in communication with the transfer chamber 164 through the second opening 162. The fresh air duct 110 is connected to the third opening 163 so that the fresh air channel 111 is in communication with the transfer chamber 164 through the third opening 163. In this way, the condensate pipe, drain pipe and fresh air pipe 110 are connected through the three-way joint 160. Standard parts are easy to purchase and convenient to improve the original structure, which is conducive to reducing the modification or production cost and facilitating daily maintenance.

[0046] Further, see Figure 2 The first switch 130 is disposed on the inner wall of the transfer channel, near the third opening 163, and the second switch 150 is disposed on the inner wall of the transfer channel, near the second opening 162. Integrating the first and second switch 130, 150 on the tee connector 160 facilitates installation and replacement, and helps improve the reliability of the cleaning unit 120 and the drain unit 140.

[0047] In one embodiment, the fresh air device 100 further includes a control component (not shown in the figure), which is electrically connected to the first switch component 130 and the second switch component 150, and is used to control the opening and closing of the first switch component 130 and the second switch component 150.

[0048] Optionally, the control component may be a single chip microcomputer, a PCB circuit board, a flexible circuit board, an FPGA, a relay or other devices.

[0049] Specifically, the control element is a PCB (not shown), and the motor of the first switch element 130 and the motor of the second switch element 150 are electrically connected to the PCB. This allows for integration within the air conditioner, resulting in ease of use, low cost, high reliability, and easy replacement and maintenance. This embodiment provides only one specific implementation of the control element, but is not intended to be limiting.

[0050] See also Figure 1 、 Figure 3 and Figure 4 , Figure 4 for Figure 1 Schematic diagram of the working state of the fresh air device 100 during cleaning, wherein the arrows represent the gas flow direction and the circles represent the cleaning medium. In one embodiment, the fresh air device 100 further includes a fresh air component 170. The fresh air component 170 includes a shell 171 and a fan 172. The shell 171 is provided with a fresh air cavity 173, an air inlet 174 and an air outlet 175. The air inlet 174 and the air outlet 175 are both connected to the fresh air cavity 173, and the fresh air channel 111 is connected to the air inlet 174. In this way, when the fresh air device 100 is operating normally, the fan 172 rotates forward, and the outside air passes through the fresh air channel 111, enters the fresh air cavity 173 from the air inlet 174, and is discharged from the air outlet 175, thereby discharging the outside air into the room. When the fresh air component 170 needs to be cleaned, the fan 172 reverses, and the indoor gas enters the fresh air chamber 173 from the air outlet 175 and is discharged into the fresh air channel 111 through the air inlet 174, providing a certain power for cleaning the fresh air pipe 110, and promoting the condensed water, which is beneficial to improving the cleaning and dust removal effect of the condensed water on the inside of the fresh air pipe 110.

[0051] In one embodiment, the present invention further provides a method for cleaning a fresh air device 100, which is used to control the fresh air device 100. The method for cleaning the fresh air device 100 includes:

[0052] The control unit determines whether the running time of the fan 172 exceeds a preset time; for example, the preset time is 30 hours;

[0053] If the running time of the fan 172 exceeds the preset time, the first switch 130 is controlled to be turned on, the second switch 150 is controlled to be turned off, and the fan 172 is controlled to be reversed; wherein, when the fan 172 is reversed, air is blown from the air inlet 174 to the fresh air channel 111;

[0054] If the running time of the fan 172 does not exceed the preset time, the second switch element 150 is controlled to be turned on and the first switch element 130 is controlled to be turned off.

[0055] In the above-described cleaning method for the fresh air device 100, when the fresh air duct 110 needs to be cleaned after long-term use, the control unit can automatically control the opening and closing of the first switch unit 130 and the second switch unit 150 based on the comparison of the operating time of the fan 172 with the preset time. If the operating time exceeds the preset time, the control unit opens the first switch unit 130, closes the second switch unit 150, and reverses the rotation of the fan 172, allowing condensed water to flow into the fresh air duct 111. The fan 172 provides power for the condensed water, thereby improving the cleaning effect. If the operating time does not exceed the preset time, the second switch 150 remains open, the first switch 130 is closed, and the fan 170 rotates forward or stops, thereby ensuring the normal operation of the fresh air device 100 and the normal discharge of condensed water, thereby automatically cleaning the fresh air duct 110 and draining the sewage from the fresh air duct 110. This cleaning method does not require disassembly of the fresh air duct 110, is convenient to operate, and is conducive to improving the cleaning efficiency of the fresh air duct 110 and ensuring the quality of the fresh air device 100.

[0056] In one embodiment, see Figure 1 , an air conditioner, the air conditioner includes a cleaning module and any one of the above-mentioned fresh air devices 100, the cleaning module is used to pass a cleaning medium into the first channel 121.

[0057] For the above-mentioned air conditioner, when the fresh air duct 110 needs to be cleaned after long-term use, the cleaning module introduces a cleaning medium into the first channel 121, and the cleaning medium flows into the fresh air channel 111, which can clean the fresh air duct 110, and the sewage is discharged from the fresh air duct 110. This cleaning method does not require disassembly of the fresh air duct 110, is convenient to operate, and is beneficial to improving the cleaning efficiency of the fresh air duct 110, ensuring the use quality of the fresh air device 100.

[0058] In one embodiment, see Figure 1The air conditioner also includes an indoor unit, which includes a heat exchanger. The cleaning module is a condenser tube, and the cleaning medium is condensed water. One end of the condenser tube is connected to the heat exchanger, and the other end of the condenser tube is connected to the end of the first channel 121 away from the fresh air duct 110. In this way, the condensed water from the air conditioner can be used to clean the inner wall of the fresh air duct 110, thereby improving the utilization rate of the condensed water and saving water resources.

[0059] The technical features of the above embodiments can be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0060] The above embodiments merely illustrate several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent. It should be noted that a person skilled in the art would be able to make various modifications and improvements without departing from the spirit of the present invention, all of which fall within the scope of protection of the present invention. Therefore, the scope of protection of the patent for this invention shall be determined by the appended claims.
