Description

Technical Field

[0001] The present disclosure relates to the technical field of electrical equipment, and particularly to an air supply device and a control method based on the air supply device. Background Art

[0002] Air supply devices are applied to various usage scenarios where air circulation is required. In some usage scenarios, it is often necessary for the air supply device to obtain air parameters in the space, such as temperature, humidity, particulate matter concentration, and other parameters, so as to switch to a suitable operating mode according to these air parameters to make the user more comfortable.

[0003] For example, the air supply device can be configured with a humidity detection device. In some usage scenarios where it is necessary to obtain the humidity in the space, the current humidity value can be obtained in real time at the current moment. If the current humidity value exceeds a certain preset humidity value, the air supply device will switch to another operating mode to meet the user's requirements.

[0004] However, in actual usage scenarios, due to the influence of many factors such as the installation environment of the air supply device, the external environment, and weather conditions, the obtained current humidity value is easily affected, resulting in the operating mode switched by the air supply device not being the ideal mode required by the customer, and further leading to an uncomfortable experience for the user.

Compared with the current method of only comparing the current humidity value with the preset humidity value, the trend and amplitude of the humidity change in the space can be judged through the historical humidity values within the preset duration, rather than just an instantaneous reading. By comparing the difference between the current humidity value and the minimum historical humidity value with the difference of the first preset humidity value, it can effectively prevent the occurrence of mis-triggering situations caused by misjudgment of the air supply device due to short-term fluctuations in the humidity in the space caused by certain factors.

[0055] To make the purpose, technical solutions and advantages of the embodiments of the present disclosure clearer, the technical solutions in the embodiments of the present disclosure will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present disclosure. Obviously, the described embodiments are part of the embodiments of the present disclosure, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present disclosure without creative efforts belong to the scope of protection of the present disclosure.

[0056] In the description of the present disclosure, it should be noted that the terms "vertical", "horizontal", "left", "right", "upper", "lower", "front", "rear" and similar expressions are for illustrative purposes only and do not represent the only implementation.

[0057] Furthermore, the ordinal numbers used in the description and claims, such as "first", "second", etc., are used to modify the corresponding elements. They do not imply or represent any ordinal number of the element itself, nor do they represent the order of one element and another element or the order in the manufacturing method. The use of these ordinal numbers is only to clearly distinguish an element with a certain name from another element with the same name.

[0058] In addition, unless otherwise clearly specified and defined, the terms "connected" and "coupled" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium. For those of ordinary skill in the art, the specific meanings of the above terms in the present disclosure can be understood in specific situations.

[0059] Based on different usage scenarios, different air supply devices will be correspondingly configured. An air supply device with a heating function, such as a bathroom heater, is widely used in indoor spaces such as bathrooms and toilets to meet the requirements of users for air supply, ventilation, and heating.

[0060] To illustrate the present disclosure, some usage scenarios are now combined to explain the embodiments of the present disclosure. It should be noted that these usage scenarios, embodiments, and implementation manners are only illustrative.

[0061] For example, when a user takes a bath (such as bathing and showering), the air supply device is often operated in the heating mode to make the indoor space relatively warm. As the bathing process progresses, while the temperature of the indoor space rises, its humidity will also increase accordingly. At this time, the air parameter conditions of high temperature and high humidity may make the user feel stuffy or other discomfort. For this reason, the prior art will configure a corresponding humidity detection device in the air supply device. The humidity detection device can obtain the current humidity value in real time at the current moment. If the current humidity value exceeds a certain preset humidity value, the air supply device will be switched to the air supply mode, ventilation mode, or other modes to reduce the temperature and / or humidity of the indoor space, so that the user has a better experience.

[0062] However, in actual usage scenarios, the humidity of the indoor space is affected by many factors such as the installation environment, external environment, and weather conditions.

[0063] For example, when the outdoor space has a relatively high humidity and there is air exchange between the indoor space and the outdoor space (such as when opening doors and windows), it will also cause the current humidity value detected by the humidity detection device to increase instantaneously. If the air supply device is switched to the ventilation mode at this time, it will cause the temperature of the indoor space to drop rapidly, which not only reduces the air heating efficiency of the indoor space but also gives the user a poor user experience.

[0064] Therefore, how to provide an air supply device and a control method to more accurately judge the user's bathing state and timely switch to a suitable operation mode has become a technical problem to be solved urgently.

[0065] Figure 1 It is a schematic diagram of the modules of the air supply device according to an embodiment of the present disclosure.

[0066] The present disclosure provides an air supply device 100, as Figure 1 shown, which includes a humidity detection device 101 and a control device 104. The humidity detection device 101 is configured to obtain the humidity value of the space where the air supply device 100 is located in a time-sequential manner. The control device 104 is communicatively connected to the humidity detection device 101 and is configured to make the air supply device 100 operate in an initial mode and, when the air parameters of the space reach the first air parameter condition, make the air supply device 100 operate in a first mode. Among them, the first air parameter condition includes obtaining the historical humidity values collected within a first preset duration with the current moment as the reference, and the humidity difference between the current humidity value and the minimum historical humidity value among the historical humidity values is greater than or equal to a first preset humidity difference; the current humidity value is collected at the current moment. Among them, the historical humidity value, the current humidity value, and other humidity values described below can all be understood as the values of relative humidity.

[0067] First Embodiment

[0068] In some exemplary embodiments, the air supply device 100 includes a main body for the installation base of other devices, such as a housing, etc. Among them, the housing includes but is not limited to being configured as a cubic structure, and it has other devices inside, such as at least a part of the humidity detection device 101, the heating device 102, the temperature detection device 103, the control device 104, the timing device 105, the air guiding device 106, the positioning device 107, and the air power device. Further, openings need to be provided at corresponding positions of the housing. If necessary, the air supply device 100 also needs to be configured with a mask having an opening so that the airflow generated by the air power device (such as an axial flow fan) can be blown out from the air outlet formed by the mask, and the air in the space where the air supply device 100 is located (such as the indoor space) can return to the air return opening formed by the mask. Furthermore, the heating device 102 includes but is not limited to using heating wires, heating blocks, and devices suitable for heating air, and it is arranged on the upstream side of the air outlet (i.e., the part where the airflow passes first).

[0069] In some exemplary embodiments, the temperature detection device 103 includes, but is not limited to, a temperature sensor, or a temperature and humidity sensor with a humidity acquisition function. Among them, the temperature detection device 103 can be configured to be integrally provided with the control device 104 (i.e., integrated into the control device 104), or can also be communicatively connected to the control device 104 in a wired or wireless manner.

[0070] Furthermore, the control device 104 includes, but is not limited to, a microcontroller (i.e., Microcontroller, abbreviated as MCU), a PLC (i.e., programmable logic controller), and other control devices 104 suitable for collecting signals and outputting control signals to other devices of the air supply device 100 based on the collected signals. Specifically, at least a part of the above devices can be controlled by the control device 104. Among them, the humidity detection device 101 is communicatively connected to the control device 104 to achieve signal and / or data transmission. Among them, the control device 104 can be integrated with a storage unit (such as flash memory, random access memory, read-only memory, electrically erasable programmable read-only memory, registers, and caches, etc.) to store the current humidity value obtained by the humidity detection device 101 as a historical humidity value. Of course, the storage unit can also be independent of the control device 104, but is communicatively connected to the control device 104.

[0071] It should be noted here that the humidity detection device 101 and the control device 104 are not the key points of protection of the present disclosure. Any detection device and control device 104 in the art that can be used for the air supply device 100 can be selected and applied, and will not be specifically elaborated.

[0072] In some exemplary embodiments, the humidity detection device 101 is configured to sequentially obtain the humidity value of the space where the air supply device 100 is located (such as the installation space, such as the above-mentioned bathroom and bathroom, etc.). Specifically, the humidity detection device 101 sequentially obtains the humidity value. Furthermore, the control device 104 uses the humidity values sequentially collected by the humidity detection device 101 at different times as historical humidity values, and calls the corresponding historical humidity values at a first preset duration.

[0073] For example, the humidity detection device 101 includes, but is not limited to, collecting the current humidity value at a cycle of 1 minute in sequence (such as RHn, where n is the collection time before the current moment. The current humidity value can be regarded as RH0, the previous 1 minute of the current moment can be regarded as RH1, and the previous 10 minutes of the current moment can be regarded as RH10). Among them, the first preset duration (i.e., ta1) includes, but is not limited to, being configured as 15 minutes, that is, ta1 = 15 minutes. Based on the first preset duration of 15 minutes, the control device 104, with the current moment as the reference, calls 15 historical humidity values within the previous 14 minutes including the current moment (i.e., RH0, RH1, RH2, RH3, RH4, RH5, RH6, RH7, RH8, RH9, RH10, RH11, RH12, RH13, RH14).

[0074] On this basis, the control device 104 further obtains the minimum historical humidity value among the above-mentioned multiple historical humidity values, that is, RHmin; and subtracts the minimum historical humidity value from the current humidity value, that is, RH0 - RHmin = △RH0; and when the humidity difference is greater than or equal to the first preset humidity difference (i.e., △RH1, including but not limited to 5%), that is, △RH0 ≥ △RH1, the air supply device 100 is switched from the initial mode to the first mode for operation. It should be understood that the minimum historical humidity value can be less than the current humidity value. The embodiments of the present disclosure are not limited thereto.

[0075] For example, the cycle for the humidity detection device 101 to detect the current humidity value can be 0.5 minute, 1 minute, 1.5 minutes, 2 minutes, 2.5 minutes, 3 minutes, and any other cycle;

[0076] Again, for example, the first preset duration can be 3 minutes, 4 minutes, 5 minutes, 6 minutes, 7 minutes, 8 minutes, 9 minutes, 10 minutes, 11 minutes, 12 minutes, 13 minutes, 14 minutes, 15 minutes, 16 minutes, 17 minutes, 18 minutes, 19 minutes, 20 minutes, and any other duration. Of course, the first preset duration needs to be greater than the cycle for the humidity detection device 101 to detect the current humidity value;

[0077] Also, for example, the first preset humidity difference can be 1%, 2%, 3%, 4%, 5%, 6%, 7%, 8%, 9%, 10%, and any other humidity difference.

[0078] In some illustrative embodiments, the initial mode can be understood as a preset mode (such as operating the air supply device 100 with parameters such as a preset air supply power, heating power, air guiding direction, etc.). In this embodiment, the initial mode is to operate at a memory temperature or an initial set temperature. Further, the first mode is other preset modes different from the above initial mode (such as at least one of the parameters such as air supply power, heating power, air guiding direction, etc. being different from the initial mode). In other embodiments, the first mode can also be an operating mode that allows users to select parameter adjustments and editing.

[0079] In such an implementation, the humidity detection device 101 of the air supply device 100 sequentially obtains the current humidity value. The control device 104 uses the current humidity values collected at each moment within a preset duration obtained by the humidity detection device 101 as historical humidity values, and compares the difference between the current humidity value and the minimum historical humidity value with the difference of the first preset humidity value to serve as the first air parameter condition. When the first air parameter condition is reached, the control device 104 causes the air supply device 100 to switch from the initial mode to the first mode.

[0080] Compared with the current method of only comparing the current humidity value with a preset humidity value, the above control device can judge the trend and amplitude of humidity change in the space through the historical humidity values within a preset duration, rather than just an instantaneous reading. By comparing the difference between the current humidity value and the minimum historical humidity value with the difference of the first preset humidity value, it can effectively prevent the influence of short-term fluctuations in the humidity in the space caused by certain factors on the operating mode of the air supply device 100.

[0081] Specifically, in the usage scenario where the humidity in the outdoor space is relatively high and the user opens the window during bathing to form air exchange between the indoor space and the outdoor space. Although when the window is opened, the high-humidity air in the outdoor space will cause the current humidity value detected by the humidity detection device 101 to suddenly increase, through the corresponding design of the above first embodiment, the air supply device will not switch from the initial mode to the first mode immediately at the moment when the humidity value suddenly increases. Instead, it will further obtain the historical humidity values within the first preset duration according to the above method, and subtract the minimum historical humidity value from the current humidity value, thereby avoiding the occurrence of mis-triggering situations caused by misjudgment of the air supply device 100.

[0082] According to the embodiments of the present disclosure, such as Figure 1As shown, the air supply device 100 further includes a timing device 105. The timing device 105 is communicatively connected to the control device 104 and is configured to obtain the first operating duration of the air supply device 100. In a state where the first operating duration is less than the first preset duration, the minimum historical humidity value is the minimum value among at least two historical humidity values within the first operating duration. In a state where the first operating duration is greater than or equal to the first preset duration, the minimum historical humidity value is the minimum value among multiple historical humidity values within the first preset duration. Wherein, the first operating duration is the duration for which the air supply device 100 operates in the initial mode.

[0083] In some exemplary embodiments, the timing device 105 includes, but is not limited to, a timer. Specifically, for example, a software timer can be used, and this software timer can be integrated into the control device 104 and implemented through programming to achieve the timing function. Of course, the timing device 105 can also use a physical timer (such as an electronic timer, etc.) to obtain the first operating duration.

[0084] When the air supply device 100 operates in the initial mode, it is possible that the first operating duration (t1) of the air supply device 100 reaches or exceeds the first preset duration (i.e., t1 ≥ ta1) before the situation of RH0 - RHmin = ΔRH0 ≥ ΔRH1 occurs; of course, it is also possible that the first operating duration (t1) of the air supply device 100 does not reach the first preset duration (i.e., t1 < ta1) and the situation of RH0 - RHmin = ΔRH0 ≥ ΔRH1 has already occurred. Therefore, for these two situations, different methods are needed to assign a value to RHmin (i.e., the minimum historical humidity value).

[0085] Therefore, in the first embodiment, still taking the first preset duration (i.e., ta1) as an example, which includes but is not limited to being configured as 15 minutes for illustration.

[0086] Assume that the first operating duration is 10 minutes, i.e., t1 = 10 minutes < ta1, then the control device 104 only obtains the minimum humidity value among all historical humidity values (i.e., RH0, RH1, RH2, RH3, RH4, RH5, RH6, RH7, RH8, RH9) within the first operating duration and assigns it as the minimum historical humidity value RHmin.

[0087] Assume that the first running duration is 18 minutes, i.e., t1 = 18 minutes > ta1. Then, the control device 104 obtains the minimum humidity value among all the historical humidity values (RH0, RH1, RH2, RH3, RH4, RH5, RH6, RH7, RH8, RH9, RH10, RH11, RH12, RH13, RH14) within the first preset duration based on the current moment, and assigns it as the minimum historical humidity value RHmin. Among them, RH0 is the historical humidity value at the current moment, RH1 is the historical humidity value 1 minute before the current moment, that is, the historical humidity value when the air supply device 100 operates in the initial mode until the 17th minute; RH14 is the historical humidity value 14 minutes before the current moment, that is, the historical humidity value when the air supply device 100 operates in the initial mode until the 4th minute; other historical humidity values are similar to RH1 and RH14, so they will not be elaborated here.

[0088] That is to say, the historical humidity value at the moment when the air supply device enters the initial mode, and the historical humidity values when it enters the initial mode and operates for the 1st minute, the 2nd minute, and the 3rd minute have been covered in a rolling manner.

[0089] Furthermore, the specific assignment method of the minimum historical humidity value can be that when the storage unit stores at least two historical humidity values, copy the minimum value among them to the minimum historical humidity value. That is, when RH1 is less than RH2, RHmin = RH1. When the storage unit stores RH3, compare RH3 with RHmin, and assign the smaller value to RHmin. That is, when RH3 is less than RHmin, RHmin = RH3. Otherwise, RHmin still maintains the current value. Until the relationship between the current humidity value and the minimum historical humidity value reaches the above condition of RH0 - RHmin = △RH0 ≥ △RH1, the air supply device 100 is switched from the initial mode to the first mode.

[0090] According to an embodiment of the present disclosure, as Figure 1 shown, the timing device 105 of the air supply device 100 is further configured to obtain the second running duration of the air supply device, and the second running duration is the running duration when the air supply device is in the first mode. The control device 104 is further configured to make the air supply device 100 exit the first mode when the air parameters in the space reach the second air parameter condition. Among them, the second air parameter condition includes that, based on the current moment, obtain the historical humidity values collected within the second preset duration, and when the humidity difference between the maximum historical humidity value and the current humidity value among the historical humidity values is greater than or equal to the second preset humidity difference, make the air supply device 100 exit the first mode.

[0091] In some exemplary embodiments, the humidity detection device 101 is still configured to sequentially obtain the humidity value of the space where the air supply device 100 is located (such as the installation space, such as the above-mentioned bathroom and bathroom, etc.). Specifically, it is similar to the above-described implementation manner, and thus will not be elaborated herein.

[0092] In some exemplary embodiments, the second preset duration (i.e., ta2) includes but is not limited to being configured as 20 minutes, that is, ta2 = 20 minutes. That is, based on the current moment, the control device 104 calls 20 historical humidity values (i.e., RH0, RH1, RH2, RH3, RH4, RH5, RH6, RH7, RH8, RH9, RH10, RH11, RH12, RH13, RH14, RH15, RH16, RH17, RH18, RH19) within the current moment and the previous 19 minutes. Among them, the obtaining method of this part of the historical humidity values is similar to that of the above embodiments, and thus will not be elaborated herein.

[0093] On this basis, the control device 104 further obtains the maximum historical humidity value among the above-mentioned multiple historical humidity values, that is, RHmax; and subtracts the current humidity value from the maximum historical humidity value, that is, RHmax - RH0 = ΔRH0; and when the difference is greater than or equal to the second preset humidity difference (i.e., ΔRH2, including but not limited to 10%), that is, ΔRH0 ≥ ΔRH2, the air supply device 100 exits from the first mode. Specifically, it can exit to the initial mode; or, it can also exit the first mode and enter the second mode (which will be described in the following embodiments).

[0094] In such an implementation manner, when the air supply device 100 operates in the first mode for a period of time, the humidity value in the space where the air supply device 100 is located significantly decreases. Therefore, in the above usage scenario, the customer's stuffy feeling may have been relieved. If the first mode is continuously maintained, it may be that the humidity in the space is too low, which may cause other discomforts such as dryness and / or coldness to the user. Therefore, through the above method, the air supply device 100 can be made to exit the first mode and enter other modes accordingly. For example, it can continue to operate in the heating mode (i.e., the initial mode) to further improve the user experience; or, for example, the air supply device can be switched to the second mode (which will be described in the following embodiments).

[0095] According to the embodiments of the present disclosure, the control device 104 is further configured that when the second operation duration is less than the second preset duration, the maximum historical humidity value is the maximum value among at least two historical humidity values within the second operation duration. When the second operation duration is greater than or equal to the second preset duration, the maximum historical humidity value is the maximum value among the multiple historical humidity values within the second preset duration. Wherein, the second operation duration is the operation duration of the air supply device 100 in the first mode.

[0096] When the air supply device 100 operates in the first mode, it is possible that the second operation duration (t2) of the air supply device 100 reaches or exceeds the second preset duration (i.e., t2≥ta2) before the situation of RHmax - RH0 = △RH0≥△RH2 occurs; of course, it is also possible that the second operation duration (t2) of the air supply device 100 does not reach the second preset duration (i.e., t2<ta2) but the situation of RHmax - RH0 = △RH0≥△RH2 has already occurred. Therefore, for these two situations, different methods are needed to assign a value to RHmax (i.e., the minimum historical humidity value).

[0097] Therefore, in the first embodiment, the second preset duration (i.e., ta2) is still described by taking it as including but not limited to being configured as 20 minutes for illustration purposes.

[0098] Suppose the second operation duration is 10 minutes, i.e., t2 = 10 minutes<ta2. Then the control device 104 only obtains the maximum humidity value among all the historical humidity values (i.e., RH0, RH1, RH2, RH3, RH4, RH5, RH6, RH7, RH8, RH9) within the second operation duration and assigns it as the maximum historical humidity value RHmax.

[0099] Suppose the second operation duration is 22 minutes, i.e., t2 = 22 minutes>ta2. Then the control device 104 obtains the maximum humidity value among all the historical humidity values (RH0, RH1, RH2, RH3, RH4, RH5, RH6, RH7, RH8, RH9, RH10, RH11, RH12, RH13, RH14, RH15, RH16, RH17, RH18, RH19) within the second preset duration based on the current moment and assigns it as the maximum historical humidity value RHmax. Among them, RH0 is the historical humidity value at the current moment, RH1 is the historical humidity value 1 minute before the current moment, that is, the historical humidity value when the air supply device 100 operates in the first mode for 21 minutes; RH19 is the historical humidity value 19 minutes before the current moment, that is, the historical humidity value when the air supply device 100 operates in the first mode for 3 minutes. Other historical humidity values are similar to RH1 and RH19, so they will not be elaborated here.

[0100] That is to say, the historical humidity values at the moment when the air supply device enters the first mode, as well as the historical humidity values at the 1st minute and the 2nd minute of operation in the first mode have been covered by rolling. Further, the specific assignment method of the maximum historical humidity value can be that when the storage unit stores at least two historical humidity values, the maximum value among them is copied to the maximum historical humidity value. That is, when RH1 is less than RH2, RHmax = RH1. When the storage unit stores RH3, compare RH3 with RHmax, and assign the smaller value to RHmax. That is, when RH3 is less than RHmax, RHmax = RH3. Otherwise, RHmax still maintains the current value. Until the maximum historical humidity value reaches the condition of RHmax - RH0 = ΔRH0 ≥ ΔRH2, the air supply device 100 exits the first mode.

[0101] For the above first embodiment, as the current humidity value is obtained sequentially, the minimum historical humidity value and the maximum historical humidity value are continuously updated by means of rolling iteration, that is, every time a current humidity value is obtained, the minimum historical humidity value and the maximum historical humidity value are assigned once. It should be understood that the embodiments of the present disclosure are not limited to this.

[0102] For example, the minimum historical humidity value and / or the maximum historical humidity value can also be assigned at intervals within a certain preset time.

[0103] Second Embodiment

[0104] According to an embodiment of the present disclosure, as Figure 1 shown, the air supply device 100 further includes a temperature detection device 103. The temperature detection device 103 is communicatively connected to the control device 104 and is configured to sequentially obtain the temperature value of the space where the air supply device 100 is located. The first air parameter condition further includes obtaining the historical temperature values collected within a first preset duration based on the current moment, and the temperature difference between the maximum historical temperature value and the current temperature value in the historical temperature values is less than or equal to a first preset temperature difference. Wherein, the current temperature value is collected at the current moment, and the maximum historical temperature value is greater than the current temperature value.

[0105] In some exemplary embodiments, the temperature detection device 103 includes, but is not limited to, a temperature sensor, a temperature and humidity sensor, and other devices suitable for measuring the temperature of the space where the air supply device 100 is located. Among them, the temperature detection device 103 can be configured to be integrally provided with the control device 104 (i.e., integrated in the control device 104), or can also be communicatively connected to the control device 104 in a wired or wireless manner.

[0106] In some illustrative embodiments, the temperature detection device 103 is configured to sequentially obtain the temperature value of the space where the air supply device 100 is located (such as the installation space, such as the above-mentioned bathroom and bathroom, etc.). Specifically, the temperature detection device 103 sequentially obtains the temperature value. Further, the control device 104 uses the temperature values sequentially collected by the temperature detection device 103 at different times as historical temperature values, and calls the corresponding historical temperature values at a first preset duration.

[0107] For example, the temperature detection device 103 includes, but is not limited to, collecting the current temperature value (such as Tn, where n is the collection time before the current moment, and the current temperature value can be regarded as T0) sequentially at a cycle of 1 minute. Among them, the first preset duration (i.e., ta1) includes, but is not limited to, being configured as 15 minutes, that is, ta1 = 15 minutes. That is, based on the current moment, the control device 104 calls 15 historical temperature values (i.e., T0, T1, T2, T3, T4, T5, T6, T7, T8, T9, T10, T11, T12, T13, T14) within the current moment and the previous 14 minutes.

[0108] On this basis, the control device 104 further obtains the maximum historical temperature value among the above-mentioned multiple historical temperature values, that is, Tmax; and subtracts the current temperature value from the maximum historical temperature value, that is, Tmax - T0 = ΔT0; and when the difference is greater than or equal to the first preset temperature difference (i.e., ΔT1, including but not limited to 5°C), that is, ΔT1 ≥ Tmax - T0 = ΔT0, the air supply device 100 is switched from the initial mode to the first mode for operation. It should be understood that the embodiments of the present disclosure are not limited to this.

[0109] For example, the cycle for the above temperature detection device 103 to detect the current temperature value can be 0.5 minutes, 1 minute, 1.5 minutes, 2 minutes, 2.5 minutes, 3 minutes, and any other cycle;

[0110] Again, the above first preset duration can be 3 minutes, 4 minutes, 5 minutes, 6 minutes, 7 minutes, 8 minutes, 9 minutes, 10 minutes, 11 minutes, 12 minutes, 13 minutes, 14 minutes, 15 minutes, 16 minutes, 17 minutes, 18 minutes, 19 minutes, 20 minutes, and any other duration. Of course, the first preset duration needs to be greater than the cycle for the temperature detection device 103 to detect the current temperature value;

[0111] Also, the first preset temperature difference can be 1°C, 2°C, 3°C, 4°C, 5°C, 6°C, 7°C, 8°C, 9°C, 10°C, and any other temperature difference.

[0112] That is to say, in the second embodiment, the first air parameter includes both the historical humidity values collected within the first preset duration with the current moment as the reference, and the comparison between the difference between the current humidity value and the minimum historical humidity value and the first preset humidity difference (similar to the first embodiment, so it will not be elaborated here); it also includes the historical temperature values collected within the first preset duration with the current moment as the reference, and the temperature difference between the maximum historical temperature value and the current temperature value in the historical temperature values is less than or equal to the first preset temperature difference. Only after the first air parameter condition simultaneously meets the above requirements for humidity and temperature, the air supply device 100 enters the first mode.

[0113] In such an implementation manner, the comparison between the difference between the current humidity value and the minimum historical humidity value and the first preset humidity difference has a similar effect to the above-mentioned first embodiment, and can effectively prevent the short-term fluctuation of the humidity in the space caused by certain factors, resulting in the mis-triggering situation caused by the misjudgment of the air supply device 100. On this basis, this implementation manner further introduces the comparison that the temperature difference between the maximum historical temperature value and the current temperature value in the historical temperature values is less than or equal to the first preset temperature difference, which can further prevent the misjudgment and mis-triggering of the air supply device 100 caused by the short-term fluctuation caused by the sudden change of temperature. And, since the air supply device 100 needs to simultaneously meet the above requirements for humidity and temperature, therefore, the air supply device 100 is also enriched with detection means, and can more accurately judge the user's bathing state and adjust the appropriate operation mode accordingly.

[0114] According to an embodiment of the present disclosure, as Figure 1 shown, the air supply device 100 further includes a timing device 105. The timing device 105 is communicatively connected to the control device 104 and is configured to obtain the first operation duration of the air supply device 100. In a state where the first operation duration is less than the first preset duration, the maximum historical temperature value is the maximum value among at least two of the historical temperature values within the first operation duration. In a state where the first operation duration is greater than or equal to the first preset duration, the maximum historical temperature value is the maximum value among the multiple historical temperature values within the first preset duration.

[0115] When the air supply device 100 operates in the initial mode, it is possible that the first operation duration (t1) of the air supply device 100 reaches or exceeds the first preset duration (i.e., t1≥ta1) before the situation of △T1≥Tmax - T0 = △T0 occurs; of course, it is also possible that the first operation duration (t1) of the air supply device 100 does not reach the first preset duration (i.e., t1<ta1) and the situation of △T1≥Tmax - T0 = △T0 has occurred. Therefore, for these two situations, different methods are needed to assign a value to Tmax (i.e., the maximum historical temperature value).

[0116] For this reason, in the first embodiment, the first preset duration (i.e., ta1), which includes but is not limited to being configured as 15 minutes, will be used for illustration.

[0117] Assume that the first operation duration is 10 minutes, i.e., t1 = 10 minutes < ta1. Then, the control device 104 only obtains the maximum temperature value among all the historical temperature values (i.e., T1, T2, T3, T4, T5, T6, T7, T8, T9, T10) within the first operation duration, and assigns it as the maximum historical temperature value Tmax.

[0118] Assume that the first operation duration is 18 minutes, i.e., t1 = 18 minutes > ta1. Then, the control device 104 obtains the maximum temperature value among all the historical temperature values (T0, T1, T2, T3, T4, T5, T6, T7, T8, T9, T10, T11, T12, T13, T14) within the first preset duration with the current moment as the reference, and assigns it as the maximum historical temperature value Tmax. Among them, T1 is the historical humidity value 1 minute before the current moment, that is, the historical humidity value when the air supply device 100 operates in the first mode until the 17th minute; T14 is the historical humidity value 14 minutes before the current moment, that is, the historical humidity value when the air supply device 100 operates in the first mode until the 4th minute; other historical humidity values are similar to T1 and T14, so they will not be elaborated here.

[0119] That is to say, the historical humidity values at the moment when the air supply device enters the first mode, as well as the historical humidity values when it enters the first mode and operates for the 1st minute, the 2nd minute, and the 3rd minute, have been covered in a rolling manner.

[0120] Furthermore, the specific assignment method of the maximum historical temperature value can be that when there are at least two historical temperature values stored in the storage unit, the maximum value among them is copied to the maximum historical temperature value. That is, when T1 is less than T2, Tmax = T1. When the storage unit stores T3, compare T3 with Tmax and assign the smaller value to Tmax, that is, when T3 is less than Tmax, Tmax = T3. Otherwise, Tmax remains the current value. Until the maximum historical temperature value reaches the above condition of △T1 ≥ Tmax - T0 = △T0, and the minimum historical humidity value reaches the above condition of RH0 - RHmin = △RH0 ≥ △RH1, the air supply device 100 is switched from the initial mode to the first mode.

[0121] Third Embodiment

[0122] According to the embodiment of the present disclosure, as Figure 1 shown, the control device 104 is further configured to cause the air supply device 100 to exit the first mode and operate in the second mode when the air parameters in the space reach the second air parameter condition.

[0123] In some illustrative embodiments, similar to the first embodiment above, the second air parameter condition includes that, when the humidity difference between the maximum historical humidity value in the historical humidity values and the current humidity value is greater than or equal to a second preset humidity difference, and the maximum historical humidity value is greater than the current humidity value, the air supply device 100 exits the first mode. That is to say, when the air supply device 100 is in the first mode and the air parameters of the further acquired space do not meet the second air parameter condition (the specific process can refer to the first embodiment above), the air supply device 100 exits the first mode and further enters the second mode.

[0124] According to an embodiment of the present disclosure, as Figure 1 shown, the control device 104 is further configured to, when the air parameters of the space reach the third air parameter condition, make the air supply device 100 exit the second mode and operate in the first mode or the initial mode. Among them, the third air parameter includes obtaining the historical humidity values collected within a third preset duration based on the current moment, and the humidity difference between the current humidity value and the minimum historical humidity value in the historical humidity values is greater than or equal to a third preset humidity difference. The current humidity value is collected at the current moment, and the minimum historical humidity value is less than the current humidity value.

[0125] According to an embodiment of the present disclosure, as Figure 1 shown, the air supply device 100 further includes a temperature detection device 103. The temperature detection device 103 is communicatively connected to the control device 104 and is configured to sequentially obtain the temperature value of the space where the air supply device 100 is located. Among them, the third air parameter condition further includes obtaining the historical temperature values collected within a third preset duration based on the current moment, and the temperature difference between the maximum historical temperature value in the historical temperature values and the current temperature value is less than or equal to a second preset temperature difference. The current temperature value is collected at the current moment, and the maximum historical temperature value is greater than the current temperature value.

[0126] In some illustrative embodiments, when the air supply device 100 operates in the second mode, the control device 104 further obtains the maximum historical temperature value, that is, Tmax, among the above-mentioned multiple historical temperature values; and subtracts the current temperature value from the maximum historical temperature value, that is, Tmax - T0 = △T0; and when the difference is less than or equal to the second preset temperature difference (that is, △T2, including but not limited to 5°C), that is, △T2 ≥ △T0 = Tmax - T0, the air supply device 100 exits the second mode of operation from the initial mode.

[0127] According to an embodiment of the present disclosure, as Figure 1As shown, the air supply device 100 further includes a timing device 105, which is communicatively connected to the control device 104 and is configured to obtain the third operation duration of the air supply device 100. In a state where the third operation duration is less than the third preset duration, the minimum historical humidity value is the minimum value among at least one historical humidity value within the third operation duration, and the maximum historical temperature value is the maximum value among at least one historical humidity value within the third operation duration. In a state where the third operation duration is greater than or equal to the third preset duration, the minimum historical humidity value is the minimum value among multiple historical humidity values within the third preset duration, and the maximum historical temperature value is the maximum value among multiple historical humidity values within the third operation duration. Wherein, the third operation duration is the operation duration of the air supply device 100 in the second mode.

[0128] In some illustrative embodiments, when the air supply device 100 operates in the second mode, the control device 104 further obtains the minimum historical humidity value, i.e., RHmin, among multiple historical humidity values within the above-mentioned third preset duration; and calculates the difference between the current humidity value and the minimum historical humidity value, i.e., RH0 - RHmin = ΔRH0; and when the difference is greater than or equal to the third preset humidity difference (i.e., ΔRH3, including but not limited to 5%), i.e., RH0 - RHmin = ΔRH0 ≥ ΔRH3, the air supply device 100 is made to exit the second mode of operation. It should be understood that the embodiments of the present disclosure are not limited thereto.

[0129] The third preset humidity difference includes but is not limited to 3%, 4%, 5%, 6%, 7%, 8%, 9%, 10% and any other humidity differences.

[0130] In some illustrative embodiments, when the air supply device 100 operates in the second mode, it is possible that the third operation duration (t3) of the air supply device 100 reaches or exceeds the third preset duration (i.e., t3 ≥ ta3) before the situation of RH0 - RHmin = ΔRH0 ≥ ΔRH3 occurs; of course, it is also possible that the third operation duration (t3) of the air supply device 100 does not reach the third preset duration (i.e., t3 < ta3) and the situation of RH0 - RHmin = ΔRH0 ≥ ΔRH3 has already occurred. Therefore, for these two situations, different methods are needed to assign a value to RHmin (i.e., the minimum historical humidity value).

[0131] In the above embodiments, the process of assigning values to the minimum historical humidity value and / or the maximum historical temperature value is similar to that in the first embodiment and the second embodiment, and therefore will not be elaborated here.

[0132] According to the embodiments of the present disclosure, as Figure 1 shown, the control device 104 is further configured to, when the air parameters in the space do not meet the third air parameter conditions, cause the air supply device 100 to exit the second mode and operate in the third mode.

[0133] In some illustrative embodiments, continuing to compare the air parameters of the space with the third air parameter condition as described above, if the air parameters at the current moment do not meet the third air parameter condition, the air supply device 100 will exit the second mode and enter the third mode, where the third mode is other operating modes other than the initial mode and the first mode described above.

[0134] In other illustrative embodiments, in addition to comparing the air parameters of the space with the third air parameter condition as described above to exit the second mode. The air supply device 100 can also be configured to exit the second mode of the air supply device 100 by other means and adjust to operate in the third mode.

[0135] In such an embodiment, during the operation of the air supply device 100, the air parameters of the space are judged based on the second air parameter condition and the third air parameter condition multiple times, so as to timely switch the operating mode of the air supply device 100. Among them, the judgment of the second space parameter can be understood as the change of the humidity value in the space further caused by the user's operation. Specifically, for example, a user closes the shower head after taking a bath, which causes the humidity value in the space to decrease, and then causes the user's perceived temperature to decrease. Therefore, the air parameters of the space can be judged again through the second air condition parameter to exit the first mode (such as the ventilation mode of exchanging indoor air with outdoor air).

[0136] However, in this state, if the user does not further adjust the operating mode of the air supply device 100 (that is, it still remains in the first mode), and when other users continue to take a bath (such as when the shower head is turned on again), the control device 104 will not be able to judge based on the first air parameter condition, and then the operating state of the air supply device 100 cannot be adjusted to the initial mode (that is, the heating mode described above), resulting in the user feeling cold. Therefore, judging the air parameters of the space based on the third air parameter condition as described above can make the air supply device 100 return to a suitable operating state. It should be understood that the embodiments of the present disclosure are not limited to this.

[0137] In other illustrative embodiments, the control device 104 is further configured to compare the third operating duration (t3) with the fourth preset duration (ta4), and in a state where the third operating duration reaches or exceeds the fourth preset duration (i.e., t3≥ta4), the air supply device 100 is made to exit the second mode.

[0138] In such an embodiment, the adjustment mode of the air supply device 100 is expanded, which can be applied to some usage scenarios where the influence of humidity on the user's perceived temperature is not significant. Specifically, it can be understood that when taking a bath in a high-temperature environment (such as in summer), due to the high environmental temperature, even if another user turns on the shower again, the temperature will not rise significantly. Therefore, it is not necessary to determine the air parameters of the space based on the third air parameter condition.

[0139] Fourth Embodiment

[0140] According to an embodiment of the present disclosure, as Figure 1 shown, the control device 104 is further configured to cause the air supply device 100 to exit the initial mode and operate in a protection mode when the air parameters of the space do not reach the first air parameter condition and the first operation duration is greater than or equal to the first protection duration. Among them, the power consumption of the air supply device 100 in the protection mode is lower than that of the air supply device 100 in the initial mode.

[0141] According to an embodiment of the present disclosure, as Figure 1 shown, the control device 104 is further configured to cause the air supply device 100 to exit the first mode and operate in a protection mode when the air parameters of the space do not reach the second air parameter condition and the second operation duration is greater than or equal to the second protection duration. Among them, the power consumption of the air supply device 100 in the protection mode is lower than that of the air supply device 100 in the first mode.

[0142] According to an embodiment of the present disclosure, as Figure 1 shown, the control device 104 is further configured to cause the air supply device 100 to exit the second mode and operate in a protection mode when the air parameters of the space do not reach the third air parameter condition and the third operation duration is greater than or equal to the third protection duration. Among them, the power consumption of the air supply device 100 in the protection mode is lower than that of the air supply device 100 in the second mode.

[0143] In some exemplary embodiments, the control device 104 is further configured to further compare whether the operation duration of the current operation mode of the air supply device 100 reaches the protection duration according to different operation modes of the air supply device 100. Specifically, if the first operation duration (t1) of the air supply device 100 in the initial mode reaches the first protection duration (tb1), that is, t1≥tb1, the air supply device 100 is switched from the initial mode to the protection mode.

[0144] And / or, if the second operation duration (t2) of the air supply device 100 in the first mode reaches the second protection duration (tb2), that is, t2≥tb2, the air supply device 100 is switched from the first mode to the protection mode.

[0145] And / or, if the third operation duration (t3) of the air supply device 100 in the second mode reaches the third protection duration (tb3), that is, t2≥tb3, the air supply device 100 is switched from the third mode to the protection mode. Among them, the first protection duration, the second protection duration, and the third protection duration can be empirical values, calculated values, or calculated values further obtained based on empirical values; the protection mode includes, but is not limited to, a shutdown mode in which all devices of the air supply device 100 stop operating, or a standby mode in which at least some devices of the air supply device 100 stop operating.

[0146] It should be noted that the air supply device 100 is adjusted from the initial mode to the first mode when it reaches the first air parameter condition; the air supply device 100 exits the first mode when it reaches the second air parameter condition; and the operation of the air supply device 100 exiting the second mode when it reaches the third air parameter condition is similar to that of the first embodiment, the second embodiment, and the third embodiment above, and therefore will not be elaborated here.

[0147] In such an embodiment, when the air supply device 100 operates in the above initial mode, first mode, and second mode, the user may leave the space due to reasons such as giving up bathing, but due to forgetting to operate the air supply device 100, it will cause the air supply device 100 to continue operating in the current mode, which will lead to unnecessary energy consumption. Therefore, the above configuration of the control device 104 can be used to make the air supply device 100 standby or shut down, thereby saving energy and effectively avoiding damage caused by the long-term operation of the devices configured in the air supply device 100.

[0148] In some exemplary embodiments, the first protection duration (i.e., tb1) includes, but is not limited to, 15 minutes, 16 minutes, 17 minutes, 18 minutes, 19 minutes, 20 minutes, 21 minutes, 22 minutes, 23 minutes, 24 minutes, 25 minutes, and any other duration. Further, the second protection duration (i.e., tb2) includes, but is not limited to, 45 minutes, 46 minutes, 47 minutes, 48 minutes, 49 minutes, 50 minutes, 51 minutes, 52 minutes, 53 minutes, 54 minutes, 55 minutes, and any other duration. Still further, the third protection duration (i.e., tb2) includes, but is not limited to, 25 minutes, 26 minutes, 27 minutes, 28 minutes, 29 minutes, 30 minutes, 31 minutes, 32 minutes, 33 minutes, 34 minutes, 25 minutes, and any other duration.

[0149] Fifth Embodiment

[0150] According to an embodiment of the present disclosure, if Figure 1As shown, the air supply device 100 further includes a heating device 102, a positioning device 107, and a wind guiding device 106. The heating device 102 is communicatively connected to the control device 104 and is configured to heat the air passing through the air supply device 100. The wind guiding device 106 is communicatively connected to the control device 104 and is configured to adjust the air supply direction of the air supply device 100. The positioning device 107 is communicatively connected to the control device 104 and is configured to locate the position of the target. Among them, the wind guiding device 106 is configured to adjust the air supply direction to be close to the target according to the target determined by the positioning device 107, or the wind guiding device 106 is configured to adjust the air supply direction to be away from the target according to the target determined by the positioning device 107.

[0151] In some exemplary embodiments, the positioning device 107 includes, but is not limited to, a radar device. Specifically, the positioning device 107 includes, but is not limited to, a millimeter-wave radar, which is disposed on the above-mentioned housing and faces the position of the target (such as a user) in space. Further, the wind guiding device 106 includes, but is not limited to, a wind guiding plate, which is rotatably disposed on the above-mentioned housing. Among them, based on the positioning of the target by the positioning device 107, the wind guiding device 106 can make the air supply direction of the air supply device 100 close to the target (i.e., the user), so that the air supply device 100 has a chasing wind mode; or, the wind guiding device 106 can also make the air supply direction of the air supply device 100 away from the target (i.e., the user), so that the air supply device 100 has a wind avoiding mode.

[0152] In such an embodiment, based on the above-mentioned heating device 102, the air supply device 100 can have a heating mode in which the air is heated by the heating device 102. Based on the above-mentioned positioning device 107 and the wind guiding device 106, the air supply device 100 can have a chasing wind mode and a wind avoiding mode. And, the wind guiding device 106 can also have a swinging air supply mode in which it swings reciprocally within a certain range. Among them, the heating mode, the chasing wind mode, the wind avoiding mode, and the swinging air supply mode can all be used as the initial mode of the air supply device 100.

[0153] To illustrate the present disclosure, the embodiments of the present disclosure will continue to be explained in combination with the usage scenario of a user taking a bath (such as bathing and showering).

[0154] In some usage scenarios, such as when the temperature in the space is relatively low (such as in winter) for the user, the air supply device 100 operates in the chasing wind mode as the initial mode, and the control device 104 controls the wind guiding device 106 to make the air supply direction of the air supply device 100 close to or face the user according to the position of the target (such as the user) in the space obtained by the positioning device 107. Among them, the initial mode is the chasing wind mode (at this time, the warm air is sent out by the air supply device 100), the first mode is the wind avoiding mode, the second mode is the chasing wind mode, and the third mode is the exhaust mode.

[0155] In such an implementation, the air supply device 100 operates in the initial mode. As the temperature and humidity in the space increase, it may make the user feel stuffy or other discomfort. For this reason, when the air parameters in the space reach the state of the first air parameter adjustment, the air supply device 100 is adjusted to the first mode, so that the air supply direction of the air supply device 100 deviates from the target, thereby reducing the user's perceived temperature. After the user finishes taking a bath, since the user turns off the shower head, the humidity value in the space can be significantly reduced. Then, when the air parameters in the space reach the second air parameters, the air supply device 100 operates in the second mode. For example, when the user is in the state of dressing after turning off the shower head, the warm air faces the user to keep the user warm during dressing. When the humidity in the space rises again, it can be understood that other users take a bath in the space again. For this reason, the air supply device 100 returns to the initial mode or the first mode to perform a similar cycle as described above. If the humidity does not continue to rise and the positioning device 107 does not obtain the target position either, the air supply device 100 can be made to stop operating after running for the third protection time.

[0156] It should be noted that the above embodiments are for the use scenarios where the user needs to increase the perceived temperature, such as when taking a bath in a use scenario with a relatively low environmental temperature in winter. If the user is in a use scenario where the perceived temperature needs to be reduced, such as when taking a bath in a use scenario with a relatively high environmental temperature in summer, the wind-avoiding mode can be used as the initial mode, the wind-avoiding mode can be used as the first mode, and the wind-chasing mode can be used as the second mode. The specific process is similar to the above, so it will not be repeated here.

[0157] Similar to the above third embodiment. In the fifth embodiment, for some use scenarios where the humidity does not have a close impact on the user's perceived temperature. Specifically, it can be understood as when taking a bath in some high-temperature environments (such as in summer). Since the environmental temperature is relatively high, even if other users turn on the shower head again, the temperature will not rise significantly. Therefore, it is not necessary to determine the air parameters in the space through the third air parameter condition. Furthermore, in this use scenario, the control device 104 is further configured to compare the third operation duration (t3) with the fourth preset duration (ta4), and in the state where the third operation duration reaches or exceeds the fourth preset duration (i.e., t3≥ta4), the air supply device 100 is made to exit the second mode.

[0158] Figure 2 It is a flowchart of the control method of the air supply device according to an embodiment of the present disclosure.

[0159] Based on the same inventive concept, the present disclosure also provides a control method based on an air supply device, including: Step S210: Make the air supply device operate in the initial mode;

[0160] Step S220: Obtain the air parameters of the space where the air supply device is located;

[0161] Step S230: When the first air parameter condition is reached, operate the air supply device in the first mode for the second operation duration;

[0162] Among them, Step S220: Obtain the air parameters of the space where the air supply device is located, including:

[0163] Sequentially obtain the humidity value of the space where the air supply device is located, and generate a historical humidity value according to the collection time;

[0164] Based on the current moment, obtain the historical humidity values collected within the first preset duration, and obtain the minimum historical humidity value among the historical humidity values;

[0165] Collect the current humidity value at the current moment, and subtract the minimum historical humidity value from the current humidity value;

[0166] Step S230: When the first air parameter condition is reached, operate the air supply device in the first mode, including:

[0167] When the humidity difference between the current humidity value and the minimum historical humidity value among the historical humidity values is greater than or equal to the first preset humidity difference, the first air parameter condition is reached.

[0168] In some exemplary embodiments, the control method further includes:

[0169] Step S240: The air supply device operates in the first mode and continues to obtain the air parameters of the space where the air supply device is located;

[0170] Step S250: Determine whether the air parameters of the space reach the second air parameter condition;

[0171] Step S260: When the air parameters of the space reach the second air parameter condition, make the air supply device exit the first mode.

[0172] In such an implementation manner, the air supply device implements obtaining the air parameters of the space where the air supply device is located, and when the air parameters of the space reach the first air parameter condition, the air supply device is switched from the initial mode to the first mode. Compared with the current method of only comparing the current humidity value with the preset humidity value, the trend and amplitude of the humidity change in the space can be judged through the historical humidity values within the preset duration, rather than just an instantaneous reading. By comparing the difference between the current humidity value and the minimum historical humidity value with the first preset humidity value difference, the occurrence of mis-triggering caused by the short-term fluctuation of the humidity in the space due to certain factors can be effectively prevented.

[0173] Figure 3It is a flowchart of a control method for a air supply device according to a first embodiment of the present disclosure.

[0174] According to an embodiment of the present disclosure, as Figure 3 shown, the control method further includes:

[0175] Step S310: Run the air supply device in an initial mode;

[0176] Step S320: Sequentially obtain the humidity value of the space where the air supply device is located, and generate a historical humidity value (i.e., RHn) based on the collection time;

[0177] Step S330: Obtain the historical humidity values collected within a first preset duration based on the current moment, and obtain the minimum historical humidity value (i.e., RHmin) among the historical humidity values;

[0178] Step S340: Collect the current humidity value at the current moment, and when the humidity difference between the current humidity value and the minimum historical humidity value among the historical humidity values is greater than or equal to a first preset humidity difference, the first air parameter condition is reached (i.e., RH0 - RHmin = ΔRH0 ≥ ΔRH1);

[0179] In this step, if the humidity difference of the current humidity value is greater than or equal to the first preset humidity difference (e.g., ΔRH1 = 5%, and RH0 - RHmin ≥ 5%), then go to step S350, otherwise go to step S310 to make the air supply device continue to run in the initial mode until the first air parameter condition is reached;

[0180] Step S350: Run the air supply device in a first mode;

[0181] Step S360: Obtain the historical humidity values collected within a second preset duration based on the current moment, and obtain the maximum historical humidity value (i.e., RHmax) among the historical humidities;

[0182] Step S370: When the humidity difference between the maximum historical humidity value and the current humidity value is greater than or equal to a second preset humidity difference, the second air parameter condition is reached (i.e., RHmax - RH0 = ΔRH0, ΔRH0 ≥ ΔRH2);

[0183] In this step, if the humidity difference of the current humidity value is greater than or equal to the second preset humidity difference (e.g., ΔRH2 = 10%, and RHmax - RH0 ≥ 10%), then go to step S380, otherwise return to step S350 to make the air supply device continue to run in the first mode until the second air parameter condition is reached;

[0184] Step S380: Make the air supply device exit the first mode.

[0185] In such an implementation manner, the initial mode is the heating mode and the first mode is the exhaust mode, which are used as the usage scenarios for illustration.

[0186] When the user takes a bath, the air supply device operates in the heating mode (i.e., the initial mode). When the user does not turn on the shower head (such as during the undressing stage), the user may feel cold. Therefore, it is necessary to quickly raise the temperature of the air in the space to make the user feel warm.

[0187] After the user turns on the shower head and starts taking a bath, both the humidity and temperature of the air in the space increase significantly. After reaching the first air parameter condition, the air supply device switches to the first mode (i.e., the exhaust mode) to operate, so that a part of the high-temperature and high-humidity air is discharged, thereby alleviating the stuffy feeling.

[0188] In the prior art, only by setting a certain preset humidity value (i.e., the humidity threshold) to judge the humidity value of the space, the air supply device may not accurately judge the humidity in the space, or may cause false triggering. For example, when the original humidity in the space is low, even if the humidity rises, it may not reach the preset humidity value; again, when the water temperature and water output of the user's shower head are different, it may also cause the preset humidity value not to be reached. Therefore, the high-temperature and high-humidity air may not be effectively discharged, thereby making the user have a bad experience.

[0189] In the embodiments of the present disclosure, the obtained minimum historical humidity value (i.e., RHmin) will reflect the relatively stable minimum humidity value in the air humidity during a certain period of time when the air supply device operates in the initial mode. Assigning the minimum value among the detected humidity values during this period to RHmin and comparing it with the current humidity value can suppress false judgments caused by reasons such as the originally relatively low relative humidity in the space or different shower temperatures and water volumes.

[0190] On this basis, the obtained maximum historical humidity value (i.e., RHmax) can be used to judge that the user has performed certain operations (such as turning off the shower head) resulting in a decrease in the humidity value in the space. At this time, the user may have finished taking a bath (such as wiping or dressing), and then control the air supply device to further adjust the operation mode to prevent the user from feeling cold when wiping. Moreover, the assignment method of rolling up the minimum historical humidity value and the maximum historical humidity value adopted in this embodiment can timely judge the user's bathing state, so as to give a faster feedback on the user's bathing state to improve the user experience.

[0191] Figure 4 Yes Figure 3 It is the flowchart of step S330.

[0192] In the embodiments of the present disclosure, such as Figure 4As shown, step S330: Obtain the historical humidity values collected within the first preset duration based on the current moment, and obtain the minimum historical humidity value among the historical humidity values, including:

[0193] Step S331: Obtain the first operation duration (i.e., t1) of the air supply device;

[0194] Step S332: Determine whether the first operation duration (i.e., t1) reaches the first preset duration (i.e., ta1);

[0195] Step S333: In the state where the first operation duration is greater than or equal to the first preset duration (i.e., t1 ≥ ta1), the minimum historical humidity value is the minimum value among the multiple historical humidity values within the first preset duration (i.e., obtain RHmin in ta1);

[0196] In this step, if the first operation duration reaches the first preset duration (e.g., ta1 = 15 minutes, t1 ≥ ta1), then obtain multiple historical humidity values within the most recent ta1 based on the current moment (i.e., 15 historical humidity values within the most recent 15 minutes), and obtain the minimum historical humidity value among them and assign it as the minimum historical humidity value;

[0197] Step S334: In the state where the first operation duration is less than the first preset duration (i.e., t1 < ta1), the minimum historical humidity value is the minimum value among at least one historical humidity value within the first operation duration (i.e., obtain RHmin in t1).

[0198] In this step, if the first operation duration does not reach the first preset duration (e.g., ta1 = 15 minutes, t1 < ta1), then obtain multiple historical humidity values within the most recent t1 based on the current moment (e.g., if t1 = 10 minutes, then obtain 10 historical humidity values), and obtain the minimum historical humidity value among them and assign it as the minimum historical humidity value;

[0199] Figure 5 Yes Figure 3 It is the flowchart of step S360.

[0200] According to an embodiment of the present disclosure, as Figure 5 shown, step S360: Obtain the historical humidity values collected within the second preset duration based on the current moment, and obtain the maximum historical humidity value among the historical humidity, including:

[0201] Step S361: Obtain the second operation duration (i.e., t2) of the air supply device, and the second operation duration is the operation duration when the air supply device is in the first mode;

[0202] Step S362: Determine whether the second operation duration reaches the second preset duration (i.e., ta2);

[0203] Step S363: In a state where the second running duration is greater than or equal to the second preset duration (i.e., t2 ≥ ta2), the maximum historical humidity value is the maximum value among multiple historical humidity values within the second preset duration (i.e., obtain Tmax in ta2);

[0204] In this step, if the second running duration reaches the second preset duration (e.g., ta2 = 20 minutes, t2 ≥ ta2), then obtain multiple historical humidity values within the most recent ta2 with the current moment as the reference (i.e., 20 historical humidity values within the most recent 20 minutes), and obtain the maximum historical humidity value among them and assign it as the maximum historical humidity value;

[0205] Step S364: In a state where the second running duration is less than the second preset duration (i.e., t2 < ta2), the maximum historical humidity value is the maximum value among at least one historical humidity value within the second running duration (i.e., obtain Tmax in t2).

[0206] In this step, if the second running duration does not reach the second preset duration (e.g., ta2 = 20 minutes, t2 < ta2), then obtain multiple historical humidity values within the most recent t2 with the current moment as the reference (e.g., if t2 = 10 minutes, then obtain 10 historical humidity values), and obtain the maximum historical humidity value among them and assign it as the maximum historical humidity value.

[0207] Figure 6 It is a flowchart of a control method for a air supply device according to a second embodiment of the present disclosure.

[0208] According to an embodiment of the present disclosure, as Figure 4 shown, it includes:

[0209] Step S410: Sequentially obtain the humidity value of the space where the air supply device is located, and generate a historical humidity value (i.e., RHn) according to the collection time;

[0210] Step S420: And sequentially obtain the temperature value of the space where the air supply device is located, and generate a historical temperature value (i.e., Tn) according to the collection time;

[0211] Step S430: Obtain the historical humidity values collected within the first preset duration (i.e., ta1) with the current moment as the reference, and obtain the minimum vertical humidity value among the historical humidity values (i.e., RHmin);

[0212] Step S440: Obtain the historical temperature values collected within the first preset duration (i.e., ta1) with the current moment as the reference, and obtain the maximum historical temperature value among the historical temperature values (i.e., Tmax);

[0213] Step S450: Collect the current humidity value at the current moment. When the humidity difference between the current humidity value and the minimum historical humidity value among the historical humidity values is greater than or equal to the first preset humidity difference (i.e., RH0 - RHmin = ΔRH0, ΔRH0 ≥ ΔRH1), at the same time, collect the current temperature value at the current moment. When the temperature difference between the maximum historical temperature value and the current temperature value is less than or equal to the first preset temperature difference (i.e., Tmax - T0 = ΔT0, ΔT1 ≥ ΔT0), the first air parameter condition is met;

[0214] In this embodiment, the air supply device not only obtains the historical humidity value (similar to the above embodiment, so it will not be elaborated here), but also further obtains the historical temperature value (i.e., Tn), and obtains the maximum historical temperature value among them and assigns it to the maximum historical temperature value (i.e., Tmax);

[0215] In this step, if both the current humidity value and the current temperature value meet the first air parameter requirements, then proceed to step S460. If any one of the current humidity value and the current temperature value does not meet the first air parameter requirements, then return to step S410 (in this step, the air supply device still operates in the initial mode);

[0216] Step S460: Make the air supply device operate in the first mode.

[0217] In such an implementation manner, the initial mode can be the heating mode, and the first mode can be the exhaust mode for illustration as the usage scenario.

[0218] When the user takes a bath, the air supply device operates in the heating mode (i.e., the initial mode). When the user does not turn on the shower head (such as during the undressing stage), the user may feel cold. Therefore, it is necessary to quickly raise the temperature of the air in the space to make the user feel warm.

[0219] After the user turns on the shower head and starts taking a bath, both the humidity and temperature of the air in the space increase significantly. After reaching the first air parameter condition, the air supply device switches to the first mode (i.e., the exhaust mode) to operate, so that a part of the high-temperature and high-humidity air is discharged, thereby alleviating the stuffy feeling.

[0220] In the prior art, the method of only judging the spatial humidity value by setting a certain preset humidity value (i.e., humidity threshold) may make the humidity judgment of the air supply device in the space inaccurate, or may cause false triggering. For example, when the humidity of the external space is high (such as in summer or the rainy season), when the user opens the doors and windows, the high-humidity air enters the space, which may cause the relative humidity of the air in the space to rise, and then exceed the preset humidity value (i.e., humidity threshold), thus causing the air supply device to make a wrong judgment. Then the air supply device operates in the first mode (i.e., the exhaust mode), discharging the warm air in the space before the user takes a bath, which makes the user feel cold and reduces the user experience.

[0221] In the embodiments of the present disclosure, on the basis of obtaining the humidity difference between the minimum historical humidity value (i.e., RHmin) and the current humidity value as described in the above embodiments, the maximum historical temperature value (i.e., Tmax) is further obtained, and the comparison between the temperature difference of the current temperature value and the first preset temperature difference is used as an auxiliary for judgment. That is, if only the high-humidity air in the external space is introduced into the space, it will not cause a significant increase in the temperature in the space. When the air temperature in the space rises, it can be considered that the user has turned on the shower head within a certain period of time, which can effectively avoid false triggering caused by simple humidity mutation, thus bringing a better experience to the user.

[0222] Figure 7 Yes Figure 6 It is the flowchart of step S450.

[0223] According to the embodiments of the present disclosure, as Figure 7 shown, step S450: Collect the current humidity value at the current moment, and when the humidity difference between the current humidity value and the minimum historical humidity value in the historical humidity values is greater than or equal to the first preset humidity difference, at the same time, collect the current temperature value at the current moment, and when the temperature difference between the maximum historical temperature value and the current temperature value is less than or equal to the first preset temperature difference, the first air parameter condition is reached, including:

[0224] Step S451: Obtain the first operation duration (i.e., t1) of the air supply device;

[0225] Step S452: Judge whether the first operation duration reaches the first preset duration (i.e., ta1);

[0226] Step S453: When the first operation duration is greater than or equal to the first preset duration (i.e., t1≥ta1), the maximum historical temperature value is the maximum value among the multiple historical temperature values within the first preset duration, and the minimum historical humidity value is the minimum value among the multiple historical humidity values within the first preset duration;

[0227] Step S454: In a state where the first operation duration is less than the first preset duration (i.e., t1 < ta1), the maximum historical temperature value is the maximum value among at least one historical temperature value within the first operation duration, and the minimum historical humidity value is the minimum value among multiple historical humidity values within the first operation duration.

[0233] Step S540: In a state where the air parameters of the space reach the second air parameter condition, the air supply device exits the first mode;

[0234] Step S550: The air supply device further operates in a second mode.

[0235] Wherein, the first mode includes a ventilation mode in which the air supply device ventilates the first space and the second space, and the second mode includes a chasing wind mode in which the air supply device approaches the target and / or a wind sheltering mode in which the air supply device moves away from the target.

[0259] Figure 12 Yes Figure 9 The flowchart of another implementation manner of step S561 of the control method shown

[0260] According to an embodiment of the present disclosure, referring to Figure 12 shown, step S561: When the air parameters in the space meet the third air parameter condition, the air supply device exits the second mode and operates in the first mode, including:

[0261] Step S5614: Obtain the humidity value of the space where the air supply device is located in a time-sequential manner, and generate a historical humidity value (i.e., RHn) based on the collection time;

[0262] Step S5615: Obtain the temperature value of the space where the air supply device is located in a time-sequential manner, and generate a historical temperature value (i.e., Tn) based on the collection time;

[0263] Step S5616: Obtain the historical humidity values collected within a third preset duration with the current moment as the reference, and obtain the minimum historical humidity value (i.e., RHmin) among the historical humidity values, and obtain the maximum historical temperature value (i.e., Tmax) collected within a third preset duration with the current moment as the reference;

[0264] Step S5617: Collect the current humidity value at the current moment, and when the humidity difference between the current humidity value and the minimum historical humidity value is greater than or equal to a third preset humidity difference, and when the temperature difference between the current temperature value and the maximum historical temperature value is greater than or equal to a third preset temperature difference, the third air parameter condition is met (i.e., RH0 - RHmin = ΔRH0, ΔRH0 ≥ ΔRH3, and Tmax - T0 = ΔT0, ΔT3 ≥ ΔT0).

[0265] According to an embodiment of the present disclosure, obtaining the maximum historical temperature value collected within a third preset duration based on the current moment in step S5616 includes:

[0266] Step S56161: Obtain the third operation duration of the air supply device;

[0267] Step S56162: In a state where the third operation duration is greater than or equal to the third preset duration, the minimum historical humidity value is the minimum value among multiple historical humidity values within the third preset duration, and the maximum historical temperature value is the maximum value among multiple historical humidity values within the third operation duration;

[0268] Step S56163: In a state where the third operation duration is less than the third preset duration, the minimum historical humidity value is the minimum value among at least one of the historical humidity values within the third operation duration, and the maximum historical temperature value is the maximum value among at least one of the historical humidity values within the third operation duration.

[0269] Steps S56161 to S56163 are similar to the method of obtaining the maximum historical temperature value by judging the first operation duration and the first preset duration in steps S451 to 454. Therefore, they will not be elaborated here.

[0270] In such an embodiment, the initial mode can be the heating mode, the first mode can be the exhaust mode, and the second mode can be a mode of closing the exhaust (such as the internal circulation mode, etc.), which is described as a usage scenario.

[0271] Refer to Figures 9 to 12 The shown embodiment can be applied to the winter operation mode, that is, the usage scenario where the user takes a bath in winter with a relatively low temperature. When the user finishes taking a bath and closes the shower head, since no more hot water is provided to the space, the relative humidity and temperature in the space will both decrease. At this time, if the next user enters the space, since the air supply device is still operating in the exhaust mode (i.e., the first mode), it may cause the user to feel cold and also prevent the air supply device from actively returning to the initial mode (i.e., the heating mode) for operation. Therefore, the air supply device is further configured with a third air parameter condition, that is, in a state where the air parameters in the space reach the third air parameter condition, the air supply device can return to the initial mode or the first mode for operation, thereby cyclically judging the first air parameter condition, the second air parameter condition, and the third air parameter condition to provide a better experience for the user.

[0272] Figure 13 is Figure 8 A flowchart of another control method for the air supply device according to the third embodiment shown.

[0273] Step S510: Operate the air supply device in the initial mode;

[0274] Step S520: Operate the air supply device in the first mode;

[0275] Step S530: Determine whether the air parameters in the space reach the second air parameter condition;

[0276] Step S540: In the state where the air parameters in the space reach the second air parameter condition, the air supply device exits the first mode;

[0277] Step S550: The air supply device further operates in the second mode;

[0278] Step S580: Determine whether the third operation duration (i.e., t3) reaches the fourth preset duration (i.e., ta4);

[0279] Step S590: In the state where the third operation duration (i.e., t3) reaches the fourth preset duration (i.e., ta4), the air supply device exits the second mode and operates in an operation mode other than the initial mode and the first mode.

[0280] Refer to Figure 13 The shown embodiment can be applied to the summer operation mode, that is, the usage scenario where the user takes a bath in the relatively cool summer. When the user finishes taking a bath and closes the shower head, since no more hot water is supplied to the space, the temperature in the space will drop. However, due to the relatively high ambient temperature, even if the user turns on the shower head again, the temperature in the space will not rise significantly in a short time. Therefore, without judging the third air parameter condition, the air supply device can exit the second mode, such as entering the standby mode, etc.

[0281] Figure 14 It is a flowchart of the control method of the air supply device according to the fourth embodiment of the present disclosure.

[0282] According to the embodiment of the present disclosure, as Figure 14 shown, the control method further includes:

[0283] Step S610: The air supply device operates in the initial mode;

[0284] Step S620: Determine whether the air parameters in the space reach the first air parameter condition;

[0285] Step S621: In the state where the air parameters in the space where it is located do not reach the first air parameter condition, further determine whether the first operation duration (i.e., t1) reaches the first protection duration (i.e., tb1);

[0286] Step S630: In the state where the air parameters in the space where it is located reach the first air parameter condition, the air supply device operates in the first mode;

[0287] Step S640: Determine whether the air parameters in the space reach the second air parameter condition;

[0288] Step S641: When the air parameters in the space do not reach the second air parameter condition, further determine whether the second operation duration (i.e., t2) reaches the first protection duration (i.e., tb2);

[0289] Step S650: When the air parameters in the space reach the second air parameter condition, the air supply device exits the first mode;

[0290] Step S660: And the air supply device operates in the second mode;

[0291] Step S670: Determine whether the air parameters in the space reach the third air parameter condition;

[0292] Step S671: When the air parameters in the space do not reach the third air parameter condition, further determine whether the third operation duration (i.e., t3) reaches the third protection duration (i.e., tb3);

[0293] Step S680: When the air parameters in the space reach the third air parameter condition, the air supply device exits the second mode;

[0294] Moreover, in steps S621, S641, and S671, if the first operation duration of the air supply device reaches the first protection duration (i.e., t1≥tb1), or if the second operation duration of the air supply device reaches the second protection duration (i.e., t2≥tb2), or if the third operation duration of the air supply device reaches the third protection duration (i.e., t3≥tb3), then perform step S690: The air supply device enters the protection mode.

[0295] In this step, the first protection duration (i.e., tb1) includes but is not limited to being configured as 20 minutes (i.e., tb1 = 20 minutes), the second protection duration (i.e., tb2) includes but is not limited to being configured as 50 minutes (i.e., tb2 = 50 minutes), and the third protection duration (i.e., tb3) includes but is not limited to being configured as 30 minutes (i.e., tb3 = 30 minutes).

[0296] In such an embodiment, as Figure 14 shown, the corresponding usage scenario can be understood as follows: If the air parameters in the space still do not reach the first air parameter condition after reaching the first protection duration, that is, the air supply device keeps operating in the initial mode. This may be caused by reasons such as the user giving up taking a bath and forgetting to turn off the air supply device, which will lead to energy waste. Therefore, in this embodiment, by judging the first operation duration, the air supply device can be controlled to enter the protection mode to stop the operation of the air supply device.

[0297] If the air parameters in the space still do not reach the second air parameter condition (or the third air parameter condition) after reaching the second protection duration (or the third protection duration), it may be caused by a failure of the temperature detection device and / or the humidity detection device. Therefore, by judging the second protection duration (or the third protection duration), the air supply device is forced to enter the protection mode to stop the operation of the air supply device. In this way, not only can energy be saved, but also the possibility of damage to other components caused by the long-term operation of the air supply device can be suppressed.

[0298] Figure 15 It is a flowchart of another control method for an air supply device according to the fourth embodiment of the present disclosure.

[0299] In some exemplary embodiments, as Figure 15 shown, the control method further includes:

[0300] Step S610: The air supply device operates in the initial mode;

[0301] Step S620: Determine whether the air parameters in the space reach the first air parameter condition;

[0302] Step S621: In a state where the air parameters in the space do not reach the first air parameter condition, further determine whether the first operation duration (i.e., t1) reaches the first protection duration (i.e., tb1);

[0303] Step S630: In a state where the air parameters in the space reach the first air parameter condition, the air supply device operates in the first mode;

[0304] Step S640: Determine whether the air parameters in the space reach the second air parameter condition;

[0305] Step S641: In a state where the air parameters in the space do not reach the second air parameter condition, further determine whether the second operation duration (i.e., t2) reaches the first protection duration (i.e., tb2);

[0306] Step S650: In a state where the air parameters in the space reach the second air parameter condition, the air supply device exits the first mode;

[0307] Step S660: And the air supply device operates in the second mode;

[0308] Step S672: Determine whether the third operation duration (i.e., t3) of the air supply device reaches the fourth preset duration (ta4);

[0309] Step S673: In a state where the third operation duration (i.e., t3) does not reach the fourth preset duration (ta4), further determine whether the third operation duration (i.e., t3) reaches the third protection duration (i.e., tb3);

[0310] Step S680: When the third operation duration (i.e., t3) reaches the fourth preset duration (ta4), the air supply device exits the second mode;

[0311] Moreover, in steps S621, S641, and S673, if the first operation duration of the air supply device reaches the first protection duration (i.e., t1≥tb1), or if the second operation duration of the air supply device reaches the second protection duration (i.e., t2≥tb2), or if the third operation duration of the air supply device reaches the third protection duration (i.e., t3≥tb3), then step S690 is performed: the air supply device enters the protection mode.

[0312] In such an embodiment, as Figure 15 shown, the judgment and mode switching for the first protection duration and the second protection duration are similar to those in the above embodiments. For the judgment of the third operation duration and the fourth preset duration, reference can be made to the summer operation mode of the embodiment shown above Figure 13 i.e., since the environmental temperature is relatively high, even if the user turns on the shower again, the temperature in the space will not rise significantly in a short time. Therefore, without the need to judge the third air parameter condition, the air supply device can enter the protection mode.

[0313] Figure 16 is a flowchart of another control method for the air supply device according to the fourth embodiment of the present disclosure.

[0314] In some exemplary embodiments, as Figure 16 shown, the control method further includes:

[0315] Step S710: The air supply device operates in the initial mode;

[0316] Step S720: Determine whether the air parameters in the space reach the first air parameter condition;

[0317] Step S721: In a state where the air parameters in the space do not reach the first air parameter condition, further determine whether the first operation duration (i.e., t1) reaches the first protection duration (i.e., tb1);

[0318] Step S730: In a state where the air parameters in the space reach the first air parameter condition, the air supply device operates in the first mode;

[0319] Step S740: Determine whether the air parameters in the space reach the second air parameter condition;

[0320] Step S741: In a state where the air parameters in the space do not reach the second air parameter condition, further determine whether the second operation duration (i.e., t2) reaches the first protection duration (i.e., tb2);

[0321] Step S750: When the air parameters in the space reach the second air parameter condition, the air supply device exits the first mode;

[0322] Step S760: And the air supply device operates in the second mode;

[0323] Step S770: Determine whether the air parameters in the space reach the third air parameter condition;

[0324] Step S771: When the air parameters in the space do not reach the third air parameter condition, further determine whether there is a target in the space;

[0325] Step S772: When the air parameters in the space reach the third air parameter condition, the air supply device exits the second mode;

[0326] Step S773: When there is a target in the space, further determine whether the third operation duration (i.e., t3) reaches the third protection duration (i.e., tb3);

[0327] Step S780: When there is no target in the space, make the air supply device operate in the third mode, and finally proceed to Step S790;

[0328] Moreover, in Steps S721, S741, and S773, if the first operation duration of the air supply device reaches the first protection duration (i.e., t1≥tb1), or if the second operation duration of the air supply device reaches the second protection duration (i.e., t2≥tb2), or if the third operation duration of the air supply device reaches the third protection duration (i.e., t3≥tb3), then proceed to Step S790: The air supply device enters the protection mode.

[0329] In such an implementation manner, as Figure 16 shown, the corresponding usage scenario can be understood as follows: If the air parameters in the space still do not reach the first air parameter condition after reaching the first protection duration, that is, the air supply device keeps operating in the initial mode. This may be caused by the user giving up taking a bath and forgetting to turn off the air supply device, etc., which will lead to energy waste. Therefore, in this embodiment, by judging the first operation duration, the air supply device can be controlled to enter the protection mode to stop the operation of the air supply device.

[0330] In such an implementation manner, the initial mode can be the wind-chasing mode, the first mode can be the wind-avoiding mode, the second mode can be the wind-chasing mode, and the third mode can be the swing mode (i.e., the air guiding device swings within a certain range to heat a part of the space in the space) as the usage scenario for description. Among them, the wind-chasing mode outputs warm air.

[0331] Taking the example of a user taking a bath in winter, the air supply device operates in the chasing wind mode as the initial mode, and controls the air guiding device to track the real-time position of the target (i.e., the user) in the space for air supply. Thus, when the user is about to take a bath and reduces clothing, the air supply device can blow warm air towards the position where the user is located, and adjust the air supply direction in real time according to the user's position.

[0332] When the user turns on the shower head to take a bath, the temperature and relative humidity in the space increase, thus reaching the first air parameter condition. For this reason, the air supply device operates in the first mode (i.e., the windward avoidance mode). At this time, since there are water droplets on the user's body surface, it can inhibit the rapid evaporation of the moisture on the user's body surface due to the wind blowing towards the user, making the user feel cold.

[0333] When the user turns off the shower head, it can be understood that the user is wiping and / or dressing. The temperature and relative humidity in the space decrease, thus reaching the second air parameter condition. For this reason, the air supply device operates in the second mode (i.e., the chasing wind mode), so that the position where the user is located is blown by warm air, thereby improving the user experience. When the air supply device does not detect a target in the space, it increases the air supply area through the swinging air mode to overall increase the temperature in the space.

[0334] If a target is detected, it will continue to return to the second mode to continuously blow air at the user. In addition, when no target is detected in the space, the above third mode can also be changed to the exhaust mode to discharge the moisture in the space, thereby preventing problems such as mildew caused by the space being in a high temperature and high humidity state for a long time.

[0335] If the user takes a bath in summer, the initial mode can be configured as the windward avoidance mode, the first mode can be configured as the windward avoidance mode, and the second mode can be configured as the chasing wind mode.

[0336] Taking the example of a user taking a bath in summer, the air supply device operates in the windward avoidance mode (i.e., the initial mode) as the initial mode, controls the air guiding device to be away from the target (i.e., the user), so that the warm air will not blow towards the customer, thereby avoiding the user feeling stuffy, and can also increase the temperature in the space, and further prevent the user (such as when the user is about to take a bath and reduces clothing) from feeling cold.

[0337] When the user turns on the shower head to take a bath, the air supply device operates in the windward avoidance mode (i.e., the first mode), thereby avoiding the cold caused by the rapid evaporation of the water droplets on the user's body surface.

[0338] When the user turns off the shower head, it can be understood that the user is wiping and / or dressing. The temperature and relative humidity in the space decrease, thus reaching the second air parameter condition. For this reason, the air supply device operates in the chasing wind mode (i.e., the second mode), so that the position where the user is located is blown by warm air, thereby improving the user experience. When the air supply device does not detect a target in the space, it increases the air supply area through the swinging air mode to overall increase the temperature in the space.

[0339] If a target is detected, continue to return to the second mode to continuously blow air at the user. In addition, when no target is detected in the space, the above-mentioned third mode can also be changed to an exhaust mode to discharge the moisture in the space, thereby preventing problems such as mildew caused by the space being in a high-temperature and high-humidity state for a long time.

[0340] In addition, the manner in which the air supply device enters the protection mode from the initial mode, the first mode, and the second mode is similar to that in the above-mentioned embodiment. Moreover, during summer bathing, when the air supply device in the second mode reaches the fourth preset duration (ta4) at the third operating duration (i.e., t3), it can also exit the second mode. The specific reasons and effects are similar to those in the above-mentioned embodiment, so they will not be elaborated here.
