[0020] In order to make the purpose, technical scheme and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0021] Embodiment 1

[0022] The present embodiment provides a wind direction control method, which combines air outlet control with dust removal control for equipment with at least two air outlets that can switch between air outlet and air inlet, such as air supply equipment such as air conditioners, fresh air blowers, and air purifiers, to prevent dust from blowing out of the air outlet and affecting the indoor air quality. The equipment involved in the present embodiment includes at least two air outlets, each of which can independently switch between air outlet and air inlet, and a filter is provided at each air outlet. Specifically, the switching of air outlet and air inlet of each air outlet can be achieved by turning a fan or setting two fans to be responsible for the air inlet and air outlet of the air outlet respectively. Each air outlet is connected to the indoor heat exchanger through a corresponding air duct, and the circulation of air inlet and outlet is achieved through different air outlet combinations, thereby realizing air supply in multiple air ducts and multiple wind directions. The "multiple" in the embodiment of the present invention is generally at least two.

[0023] Figure 1 is a flow chart of the wind direction control method provided in the first embodiment of the present invention. Figure 1 As shown, the method comprises the following steps:

[0024] S101, obtaining a blockage value of a filter of a target air outlet, wherein the target air outlet is an air outlet of a target wind direction.

[0025] S102: If the blockage value is less than a first preset threshold, the corresponding air outlet is controlled to operate in a target wind direction.

[0026] S103: If the blocking value is greater than or equal to the first preset threshold, operation according to the target wind direction is not allowed.

[0027] The first preset threshold value can be preset according to actual conditions. If the blockage value is less than the first preset threshold value, it means that the dust accumulation on the filter is not high, and the corresponding air outlet can continue to discharge air without affecting the air quality. If the blockage value is greater than or equal to the first preset threshold value, it means that the dust accumulation on the filter reaches a certain level, and the corresponding air outlet continues to discharge air, which will cause dust to be blown out, affecting the air quality and user comfort, so the device is not allowed to operate according to the target wind direction.

[0028] The wind direction control method of this embodiment, for a device with at least two switchable air outlets and air inlets, obtains the blockage value of the filter of the air outlet of the target wind direction. If the blockage value is less than a first preset threshold value, the corresponding air outlet is controlled to operate in the target wind direction. Otherwise, it is not allowed to operate in the target wind direction. In this way, the air outlet control is combined with the dust removal control to avoid the air outlet blowing out dust and affecting the indoor air quality, thereby ensuring user comfort and improving user experience of the product.

[0029] Take the duct air conditioner as an example. During the operation of the duct air conditioner, the air inside the duct air conditioner flows from the air inlet to the air outlet, and the dust will be intercepted and accumulated on the filter at the air inlet. Figure 2A , A is the air inlet, B is the air outlet. When air flows from the air inlet A to the air outlet B, dust is intercepted by the filter of the air inlet A, and the filter of the air inlet A will accumulate dust. If the air inlet and outlet directions are reversed, such as Figure 2B As shown, the air flows from B to A, the dust is intercepted at the filter of B, and the filter of B will accumulate dust.

[0030] For an indoor unit with multiple air outlets and multiple air ducts (i.e., the indoor unit has at least two air outlets that can be switched to supply and receive air and air ducts that correspond to the air outlets one by one), dust is intercepted at different air outlets according to the channels through which the air actually flows. Figure 3 The multi-air outlet and multi-duct indoor unit shown in the figure is taken as an example to explain Figure 3 In the indoor unit, there are four air outlets, and the four air outlets can be changed into 12 different wind ducts. Figure 3Four of them are shown, namely wind direction one (1 in, 2 out), wind direction two (3 in, 2 out), wind direction three (2 in, 1 out) and wind direction four (2 in, 3 out), and the rest can be obtained by analogy. Wind direction one intercepts dust at air outlet 1, wind direction two intercepts dust at air outlet 3, wind direction three intercepts dust at air outlet 2, and wind direction four intercepts dust at air outlet 2. Therefore, when the air outlet is used as an air inlet, the filter of the air outlet will accumulate dust. When the air outlet is used as an air outlet, if it is not controlled, dust will be blown out, affecting the user's comfort. Each time the wind direction is set in this embodiment, it is necessary to judge the filter blockage of the air outlet under the target wind direction, and perform corresponding operations according to the filter blockage. For example, if the filter pollution is particularly serious, it is necessary to perform the filter cleaning operation first, otherwise the air outlet corresponding to the filter is not allowed to be used as an air outlet to avoid blowing out dusty air and causing user discomfort.

[0031] Furthermore, obtaining the blockage value of the filter of the target air outlet includes: receiving a wind direction setting instruction; determining the target air outlet according to the wind direction setting instruction; and reading the blockage value of the filter of the target air outlet from the stored filter information.

[0032] The wind direction setting instruction may be a startup instruction that defaults to the wind direction when the machine was shut down during the last operation, or may be a wind direction switching instruction during operation. According to the wind direction setting instruction, the target wind direction and the corresponding air outlets involved in the target wind direction may be known.

[0033] The blockage value of the air outlet filter can be calculated once when the calculation timing is met according to the filter blockage value calculation rules, so as to realize the full monitoring of the dust accumulation degree of the filter. Specifically, the calculation timing of each air outlet filter can be the same or different. The filter information can include the blockage value calculated for each air outlet filter each time. Accordingly, when reading the blockage value of the filter of the target air outlet, the most recent blockage value of the filter is read; or, the filter information can only include the most recent calculated blockage value of each air outlet filter. This embodiment uses the stored filter information to simply and quickly obtain the filter blockage value to assist in air outlet control.

[0034] In one embodiment, before obtaining the blockage value of the filter of the target air outlet, it also includes: for the filter of each air outlet, obtaining the current blockage parameter of the filter according to the filter blockage value calculation rule; determining the current blockage value of the filter according to the current blockage parameter; storing the current blockage value of the filter in the filter information.

[0035] Among them, the calculation rules of the filter blockage value include: the blockage parameters used, the specific algorithm and the calculation time. The blocking parameter is one of the following: the air volume output when the air outlet corresponding to the filter is used as the air outlet, the wind pressure output when the air outlet corresponding to the filter is used as the air outlet, or the cumulative running time when the air outlet corresponding to the filter is used as the air inlet. The blocking parameters and specific algorithms used by each air outlet filter may be the same or different. The blocking value is stored in the filter information, and the result of each calculation may be stored, or it may be stored in a way that covers the previous calculation value of the same filter. This embodiment distinguishes the wind direction, and relies on the blocking parameter to realize the accurate calculation and update of the filter blockage value, thereby ensuring the accuracy of the combined control of the air outlet and dust removal.

[0036] It should be noted that the embodiment of the present invention focuses on the combined control of air outlets and dust removal. In addition to the above-mentioned blockage parameters, the specific calculation of the filter blockage value can also be calculated using other existing methods, which is not described in detail in the embodiment of the present invention.

[0037] The following is an example of the determination of the filter blockage value, taking the cumulative running time when the air outlet corresponding to the filter is used as the air inlet as an example. For each wind direction, the cumulative running time of the wind direction is counted, and the blockage value of the filter at the air inlet in the wind direction is determined based on the correspondence between the preset time and the blockage value. In other words, after each operation in a certain wind direction, the blockage value corresponding to the current running time is added to the previously accumulated calculated blockage value of the filter at the air inlet in the wind direction.

[0038] In one embodiment, after obtaining the blockage value of the filter of the target air outlet, the method further includes: if the blockage value is greater than or equal to the first preset threshold, outputting filter cleaning prompt information; before obtaining the information that the filter of the target air outlet has been cleaned, if any instruction to use the target air outlet as an air outlet is received, it is rejected. If the blockage value is greater than or equal to the second preset threshold, outputting filter replacement prompt information, wherein the first preset threshold is less than the second preset threshold; before obtaining the information that the filter of the target air outlet has been replaced, if any instruction to use the target air outlet as an air outlet is received, it is rejected.

[0039] When the dust accumulation on the filter reaches a certain level, in addition to refusing to execute the current wind direction setting command, relevant prompt information can also be output to remind the user to clean or replace the filter in time, so that after cleaning or replacing the filter, the air outlet corresponding to the filter can be used normally as the air outlet. And before the filter of the target air outlet has been cleaned or replaced, any command to use the target air outlet as the air outlet is rejected, thereby avoiding the situation where the air outlet corresponding to the filter with a certain degree of dust accumulation is used as the air outlet and dust is blown out. At this time, other qualified air outlets can be used as air outlets to achieve air circulation and ensure user comfort.
