[0026] The optional embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0027] Example 1

[0028] This embodiment provides a method for handling abnormal air vent communication, which is applied to an air conditioning device having at least two air vents, including an air outlet and an air return vent. Depending on the installation position of the air vent, air can be discharged upward or downward or left and right.

[0029] The following describes a dual-inlet control air conditioner with up-and-down airflow as an example. The up-inlet can be located in the upper room or on the side of the ducted unit, while the down-inlet can be located in the lower room or on the bottom of the ducted unit. Together, the up-inlet and down-inlet form the indoor air circuit.

[0030] Figure 1 FIG. 1 is a flow chart of a method for handling abnormal vent communication according to an embodiment of the present invention. Figure 1 As shown, the method includes the following steps:

[0031] Step S101, detecting whether the communication between the air outlet and the return air outlet and the host is abnormal;

[0032] Step S102: When an abnormality is detected, the working state of the air outlet and the return air outlet is adjusted or maintained to ensure that the air conditioning equipment sweeps air normally.

[0033] In this embodiment, when a communication abnormality occurs at the air vent, the air vent will not be directly closed. Instead, the air vent will be adjusted or maintained in its working state to ensure that the air conditioning equipment can discharge air normally and the air circulation of the air circuit is ensured.

[0034] Specifically,

[0035] 1) When abnormal communication between the air outlet and the host is detected, the air outlet is switched to the return air working state, and the air guide panel in the air outlet is controlled to open to the maximum angle to achieve maximum efficiency of return air; then, the return air outlet is switched to the outlet working state, and the air sweeping action of the air guide panel in the return air outlet is controlled according to the air sweeping instruction issued by the host to the air outlet.

[0036] For air-conditioning equipment with upper and lower double air outlets, if the air outlet communication is abnormal, it will automatically switch to the return air outlet, and the return air outlet will switch to the air outlet, thereby ensuring the normal air sweeping.

[0037] 2) When abnormal communication between the return air vent and the host is detected, the current working status of the return air vent and the air outlet is maintained.

[0038] 3) When it is detected that both the air outlet and the return air outlet are communicating abnormally with the host, both the air outlet and the return air outlet are switched to the return air working state.

[0039] The air vents function differently (outlet or return air) in different operating modes. In cooling mode, the upper vents act as outlets, while the lower vents act as return air, creating a waterfall-like cooling effect. In heating mode, the upper vents act as return air, while the lower vents act as outlets, creating a blanket-like heating effect with hot air flowing from bottom to top, more suitable for both cooling and heating needs.

[0040] The upwind and downwind vents of the air-conditioning equipment are each equipped with a microprocessor and a sweeping motor. The air guide panel is controlled according to the different air outlet and return air roles of the air vent. When used as an air outlet, the air guide panel needs to be controlled to achieve directional air supply or sweeping. When used as a return air outlet, the air guide panel needs to be controlled to open to the maximum angle to achieve the most efficient return air.

[0041] Figure 2 This is a structural diagram of the air outlet and the host according to an embodiment of the present invention. Figure 2 The following describes an air conditioner with one air outlet and one return air outlet as an example, but the number of air outlets and return air outlets is not limited to this. Figure 2 As shown, the multi-air outlet air conditioning device of the present invention is composed of the following parts:

[0042] Host: Responsible for judging the current user's control instructions, such as running cooling mode or heating mode, and air sweep control instructions, and sending instructions to the upper and lower air vents to control the air guide panels;

[0043] Upstream vent: Receives control commands from the host computer and drives the motor to control the opening angle of the air guide panel, thereby completing the air sweeping action. Generally, it serves as the air outlet in cooling mode and the return air outlet in heating mode.

[0044] Downstream vent: Receives control commands from the host computer and is responsible for driving the motor to control the opening angle of the air guide panel, thereby completing the air sweeping action. Generally, it serves as the air outlet in heating mode and the return air vent in cooling mode.

[0045] The main unit is composed of a microprocessor and a communication circuit. The upper and lower air vents are composed of a microprocessor, a communication circuit, a sweeping motor, a drive circuit, and an air guide panel.

[0046] The following describes the solutions for handling abnormal air outlet communication under different operating modes (cooling mode or heating mode).

[0047] 1) If the host determines that the current operating mode is cooling, it designates the upper air outlet as the outlet and the lower air outlet as the return air outlet. Upon receiving a command from the host, the upper air outlet switches to outlet control, performing sweeping or directional air supply according to the host's command. The lower air outlet opens to its maximum angle to achieve maximum return air efficiency.

[0048] When the upper air outlet detects a communication interruption with the host, it automatically switches to a return air outlet, opening the air guide panel to its maximum angle to achieve maximum air return efficiency. When the lower air outlet detects a communication failure with the host, it automatically switches to an outlet and sweeps the air through the air guide panel according to the sweep command sent by the host to the upper air outlet. This ensures normal air sweeping without affecting the user experience.

[0049] When the lower air outlet detects that the communication with the host is interrupted, the return air outlet control remains unchanged and does not close. At this time, the upper air outlet also maintains the air outlet control.

[0050] When the communication between the upper and lower air outlets fails at the same time, both will switch to return air outlets. At this time, air circulation can be formed normally, but air sweeping cannot be achieved. However, the impact on users can be reduced.

[0051] 2) If the host determines the current operating mode is heating, it designates the upper vent as the return air vent and the lower vent as the outlet. Upon receiving a command from the host, the lower vent switches to outlet control, performing sweeping or directional air supply as directed by the host. The upper vent opens to its maximum angle for maximum return air efficiency.

[0052] When the downflow outlet detects a communication interruption with the host, it automatically switches to a return air outlet, opening the air guide panel to its maximum angle to achieve maximum return air efficiency. When the upflow outlet detects a communication failure with the host, it automatically switches to an outlet and sweeps the air through the air guide panel according to the sweep command sent by the host to the downflow outlet. This ensures normal air sweeping without affecting the user experience.

[0053] When the upper air outlet detects that the communication with the host is interrupted, the return air outlet control remains unchanged and does not close. At this time, the lower air outlet also maintains the air outlet control.

[0054] When the communication between the upper and lower air outlets fails at the same time, both will switch to return air outlets. At this time, air circulation can be formed normally, but air sweeping cannot be achieved. However, the impact on users can be reduced.

[0055] The above solution only points out the device form of upper and lower air outlets. In fact, it can also be a left and right air outlet, or a device form with more than two air outlets. This air outlet and return air function switching solution can be adopted to achieve flexible handling when the air outlet communication fails and the host does not know the role assigned to itself, ensuring normal air supply without affecting the user experience.

[0056] Example 2

[0057] Corresponding to Figure 1 The present embodiment provides a method for handling abnormal air outlet communication. Figure 3 The structural block diagram of the tuyere communication abnormality processing device shown in FIG. 1 includes:

[0058] The communication detection module 10 is used to detect whether the communication between the air outlet and the return air outlet and the host is abnormal;

[0059] The control module 20 is used to adjust or maintain the working status of the air outlet and the return air outlet when an abnormality is detected to ensure that the air conditioning equipment sweeps air normally.

[0060] In this embodiment, when a communication abnormality occurs at the air vent, the air vent will not be directly closed. Instead, the air vent will be adjusted or maintained in its working state to ensure that the air conditioning equipment can discharge air normally and the air circulation of the air circuit is ensured.

[0061] Specifically, the control module 20 includes:

[0062] The first processing unit is used to switch the air outlet to the return air working state and the return air outlet to the outlet working state when detecting abnormal communication between the air outlet and the host;

[0063] The first processing unit is also used to: after the air outlet is switched to the return air working state, control the air guide panel in the air outlet to open to the maximum angle to achieve maximum efficiency return air; and after the return air outlet is switched to the outlet working state, control the air sweeping action of the air guide panel in the return air outlet according to the air sweeping instruction issued by the host to the air outlet.

[0064] The second processing unit is used to maintain the current working state of the return air vent and the air outlet when it is detected that the communication between the return air vent and the host is abnormal.

[0065] The third processing unit is used to switch the air outlet and the return air outlet to the return air working state when it is detected that the air outlet and the return air outlet both communicate abnormally with the host.

[0066] This embodiment optimizes the handling of air outlet communication anomalies to prevent direct closure of the outlet when a fault occurs, impacting air circulation. This ensures continuous heating or cooling while also maintaining effective air sweeping, thereby ensuring user comfort.

[0067] This embodiment further provides an air conditioning device, which includes at least two air vents and a host, wherein the at least two air vents include an air outlet and a return air vent, and also includes the above-mentioned air vent communication abnormality processing device.

[0068] The air vents are equipped with a microprocessor, communication circuit, drive circuit and air guide panel, and the host is equipped with a microprocessor and communication circuit;

[0069] The microprocessor in the air vent is used to detect whether the communication circuit between the communication circuit and the host is abnormal. When an abnormality is detected, it adjusts or maintains its own working state to ensure the normal air sweeping of the air conditioning equipment;

[0070] When the microprocessor in the host detects a communication anomaly at one of the air outlets, it sends a communication anomaly message to the microprocessor of the other air outlet.

[0071] Based on the technical solution of this embodiment, if an air outlet anomaly occurs, if the problem is at the outlet, the outlet's microprocessor can determine that communication with the host has been lost and can switch to a return air outlet (without performing a purge). Upon detecting the communication failure between the host and the air outlet, the original return air outlet will switch to an outlet and execute the purge action issued by the host to the original air outlet. This completes the role change between the air outlet and the return air outlet, thereby ensuring normal air circulation in the circuit without affecting the user experience.
