[0039] The present application describes a plurality of embodiments, but the description is exemplary rather than limiting, and it will be apparent to those of ordinary skill in the art that many more embodiments and implementations can be within the scope of the embodiments described in the present application. Although many possible combinations of features are shown in the drawings and discussed in the specification, many other combinations of the disclosed features are possible. Unless specifically intended otherwise, any feature or element of any embodiment can be used with any other feature or element of any other embodiment, or in any other embodiment, or in a new embodiment.

Embodiments are, therefore, not to be limited by the other limitations that are presented in this summary alone or in any combination. Moreover, various modifications and changes can be made within the scope of the claims that follow.

[0041] Furthermore, in describing representative embodiments, the specification can have presented the method and / or process as a particular sequence of steps. However, to the extent that the method or process depends on the particular order of steps, the method or process should not be limited to the

[0042] In the related art, the hand dryer for bathroom cabinet on the market currently uses an existing hair dryer as a hand dryer. When used as a hair dryer, it can be used for blow-drying hair. When idle, it is used as a hand dryer by means of a hand dryer base and an infrared pair tube. As shown in Figure 1 The hair dryer 11 is placed on the hand dryer base 12 to be used as a hand dryer. When used as a hand dryer, the decorative cover 13 on the hand dryer base is removed, and the air from the hair dryer is blown out of the air duct in the hand dryer base to function as a hand dryer.

[0043] The hair dryer matched with the hand dryer base can be different types of hair dryers. Different types of hair dryers have different blowing principles, and accordingly, the air speed and blowing temperature are also different, so the temperature used as a hand dryer is also different.

[0044] However, in the related art, the infrared sensing distance is fixed, so when the matched hair dryer itself has a relatively high temperature, the user feels a relatively high temperature at the fixed sensing distance, and the user's body feeling is not good.

[0045] Therefore, an embodiment of the present application provides a hand drying sensing distance acquisition method applied to a hand dryer base. The hand dryer base includes an air duct with an air outlet and a temperature sensor arranged on the air duct. As shown in Figure 2 The method includes the following steps:

[0046] Step 201: In response to the air outlet part of the hair dryer being placed in the air duct and the hair dryer being in a working state, the temperature sensed by the temperature sensor when the air blown by the hair dryer passes through the air duct from the air outlet part is acquired.

[0047] Step 202: The target sensing distance for starting the hair dryer to be used as a hand dryer is determined according to the temperature sensed by the temperature sensor.

[0048] The sensing distance refers to the distance between the user's hand and the air outlet of the air duct.

[0049] The hand dryer base in the hand dryer sensing distance acquisition method provided by the embodiments of the present application can be as shown in the accompanying drawings Figure 3 The hand dryer base comprises a body 301, an air duct 302 provided on the body 301 and having an air outlet, a temperature sensor 303 provided on the air duct 302, and a control device 304 provided on the body 301.

[0050] The temperature sensor 303 is configured to sense the temperature when the air blown by the hair dryer passes through the air duct 302 from the air outlet.

[0051] The control device 304 is electrically connected to the hair dryer and the temperature sensor 303, and is configured to determine a target sensing distance for starting the hair dryer as a hand dryer according to the temperature sensed by the temperature sensor 303.

[0052] The temperature sensor can be arranged on the air blowing path of the air duct through which the air blown by the hair dryer passes from the air outlet. When the hair dryer blows air, the air blown by the hair dryer passes through the temperature sensor during the process of passing through the air duct from the air outlet, and the temperature sensor senses the temperature. In order to better sense the temperature of the air, the temperature sensor can be arranged on the inner wall of the air duct, and the specific position can be arranged at a position close to the side of the air outlet facing the air outlet or a position far from the air outlet. When the specific position of the temperature sensor is at a position close to the side of the air outlet facing the air outlet or a position far from the air outlet, the air blown by the hair dryer can reach the temperature sensor after passing through a short distance, so the temperature loss is small and the temperature sensed by the temperature sensor is high. When the specific position of the temperature sensor is at a position far from the side of the air outlet facing the air outlet or a position close to the air outlet, the air blown by the hair dryer needs to pass through a long distance to reach the temperature sensor, so the temperature loss is large and the temperature sensed by the temperature sensor is low.

[0053] When the target sensing distance is determined, the hair dryer can be started as a hand dryer by using the target sensing distance. When the hair dryer is used as a hand dryer, the hair dryer needs to be in a normal open state, and the hair dryer socket needs to be plugged into a two-hole socket. The control device controls the on-off of the socket power supply to control the operation of the hair dryer, or the control device controls the main control board in the hand dryer base to control the on-off of the socket power supply to control the operation of the hair dryer.

[0054] In an exemplary example, the target sensing distance for starting the hair dryer as a hand dryer according to the temperature sensed by the temperature sensor comprises:

[0055] The hand drying temperature at the preset initial sensing distance is calculated according to the temperature sensed by the temperature sensor, and the target sensing distance is obtained by adjusting the initial sensing distance through comparison with the target hand drying temperature; wherein the initial sensing distance is a preset sensing distance for initially starting the hair dryer to be used as a hand drying device;

[0056] Alternatively, the target sensing distance is determined according to the temperature sensed by the temperature sensor and the target hand drying temperature.

[0057] Alternatively, the target sensing distance is determined according to the temperature sensed by the temperature sensor and the preset corresponding relationship between the sensed temperature and the sensing distance.

[0058] In order to obtain the target sensing distance of the hair dryer used as a hand drying device, the following methods can be used:

[0059] First, an initial sensing distance for initially starting the hair dryer to be used as a hand drying device is set, then the hand drying device is started according to the initial sensing distance, and the temperature is sensed by the temperature sensor, and the hand drying temperature at the initial sensing distance is calculated according to the sensed temperature, and then the calculated hand drying temperature is compared with the target hand drying temperature to adjust the initial sensing distance to obtain the target sensing distance.

[0060] The following methods can also be used:

[0061] The hand drying device is not started by setting an initial sensing distance, but is directly started by other methods, and the target sensing distance is determined according to the temperature sensed by the temperature sensor and the target hand drying temperature.

[0062] The following methods can also be used:

[0063] The corresponding relationship between the sensed temperature and the sensing distance is obtained by a large number of experiments, wherein the sensed temperature in the corresponding relationship refers to the temperature sensed by the temperature sensor when the hair dryer at different blowing temperatures is erected on the hand drying device base and the air outlet is placed in the air duct for blowing, the sensing distance in the corresponding relationship refers to the sensing distance required to reach the preset target hand drying temperature under the condition of different temperatures sensed by the sensor, and the sensing distance corresponding to each temperature sensed by the sensor can be obtained by moving away from the air duct from the air outlet of the air duct and measuring the temperature, and the distance moved to when the measured temperature reaches the target hand drying temperature is taken as the sensing distance corresponding to the temperature sensed by the sensor.

[0064] The correspondence between the sensed temperature and the sensed distance can be stored as a table, so that after obtaining the temperature sensed by the temperature sensor, the corresponding target sensed distance can be directly obtained by table lookup, i.e., the temperature of the air blown by the hair dryer when reaching the obtained target sensed distance is the target hand drying temperature.

[0065] In an exemplary example, when the target sensed distance is obtained in a manner that the hand drying temperature at the initially set sensed distance is calculated according to the temperature sensed by the temperature sensor, and the initially set sensed distance is adjusted by comparison with the target hand drying temperature, the hand dryer base further comprises a distance detection module, and the working state of the hair dryer is realized in response to the following manner:

[0066] obtaining the sensed distance detected by the distance detection module;

[0067] comparing the detected sensed distance with the initially set sensed distance, and starting the hair dryer in response to the comparison result that the detected sensed distance is less than or equal to the initially set sensed distance.

[0068] The hand dryer base in the hand drying sensed distance obtaining method provided by the embodiments of the present application can be as shown in Figure 4 The hand dryer base comprises a body 301, a wind tube 302 provided on the body 301 and having an air outlet, a temperature sensor 303 provided on the wind tube 302, a control device 304 provided on the body 301, and a distance detection module 305 provided on the hand dryer base.

[0069] The temperature sensor 303 is configured to sense the temperature when the air blown by the hair dryer passes through the wind tube from the air outlet;

[0070] The distance detection module 305 is configured to detect the sensed distance;

[0071] The control device 304 is electrically connected to the temperature sensor 303 and the distance detection module 305, and is configured to obtain the sensed distance detected by the distance detection module 305, compare the detected sensed distance with the initially set sensed distance, and start the hair dryer in response to the comparison result that the detected sensed distance is less than or equal to the initially set sensed distance; obtain the temperature sensed by the temperature sensor 303, and obtain the target sensed distance by adjusting the initially set sensed distance according to the comparison between the temperature sensed by the temperature sensor 303 and the target hand drying temperature.

[0072] The distance detection module can be arranged at the air outlet of the air cylinder, so that the distance detected by the distance detection module is the distance between the user's hand and the air outlet of the air cylinder; it can also be arranged at a position other than the air outlet of the air cylinder, so that the distance detected by the distance detection module needs to be reduced by the distance between the distance detection module and the air outlet of the air cylinder, and the distance between the user's hand and the air outlet of the air cylinder is obtained.

[0073] In actual application, the distance detection module can be an infrared distance measuring module, and the distance measuring principle of the infrared distance measuring module is the reflection energy principle, that is, a beam of infrared light is irradiated to the surface of the measured object, and the reflected light energy of the measured object is received to determine the distance. Therefore, when the infrared distance measuring module is used for distance measurement, the infrared distance measuring module emits a beam of infrared light to the user's hand, and receives the reflected light energy of the user's hand to determine the distance between the user's hand and the air outlet of the air cylinder.

[0074] In an exemplary example, when the target sensing distance is determined according to the temperature sensed by the temperature sensor and the target hand drying temperature, the hand drying seat further comprises an instruction receiving module, and the working state of the hair dryer is realized by the following response:

[0075] Obtaining the hair dryer working instruction received by the instruction receiving module;

[0076] Starting the hair dryer according to the obtained hair dryer working instruction.

[0077] The hand drying seat in the hand drying sensing distance acquisition method provided by the embodiment of the present application can be as shown in the figure Figure 5 The hand drying seat in the hand drying sensing distance acquisition method provided by the embodiment of the present application can be as shown in the figure

[0078] The temperature sensor 303 is configured to sense the temperature when the air blown by the hair dryer passes through the air cylinder through the air outlet;

[0079] The instruction receiving module 306 is configured to receive the hair dryer working instruction;

[0080] The control device 304 is electrically connected with the temperature sensor 303 and the instruction receiving module 306, and is configured to obtain the hair dryer working instruction received by the instruction receiving module 306, start the hair dryer according to the obtained hair dryer working instruction, obtain the temperature sensed by the temperature sensor 303, and determine the target sensing distance according to the temperature sensed by the temperature sensor 303 and the target hand drying temperature set in advance.

[0081] The instruction receiving module can be a signal receiver. When the instruction receiving module is a signal receiver, the signal receiver receives a control signal sent by a user through a signal transmitter, and determines whether the instruction corresponding to the control signal is a hair dryer working instruction. When it is determined that the hair dryer working instruction is the hair dryer working instruction, the signal receiver sends the hair dryer working instruction to the control device, and the control device starts the hair dryer.

[0082] In an exemplary embodiment, the target sensing distance is obtained by adjusting the initial sensing distance according to a comparison between the hand drying temperature at the initial sensing distance calculated according to the temperature sensed by the temperature sensor and a target hand drying temperature, including:

[0083] The hand drying temperature at the initial sensing distance is calculated according to the temperature sensed by the temperature sensor and the position information of the temperature sensor, or according to the temperature sensed by the temperature sensor and a first temperature difference value, or according to the temperature sensed by the temperature sensor and a first temperature difference value coefficient.

[0084] The calculated hand drying temperature is compared with the target hand drying temperature, and the initial sensing distance is adjusted to obtain the target sensing distance according to the comparison result.

[0085] The hand drying temperature at the initial sensing distance calculated according to the temperature sensed by the temperature sensor and the first temperature difference value can be obtained by the following method: a temperature difference between the temperature sensed by the temperature sensor when the air blown by the hair dryer at different temperatures passes through the air duct of the air outlet part and the hand drying temperature at the initial distance is obtained through a large number of experiments, and then the first temperature difference is obtained through mathematical processing, such as mean value processing. In this way, when the temperature sensed by the temperature sensor is sensed, the hand drying temperature at the initial sensing distance is calculated by subtracting the first temperature difference from the sensed temperature.

[0086] The hand drying temperature at the initial sensing distance calculated according to the temperature sensed by the temperature sensor and the first temperature difference value can be obtained by the following method: a temperature difference between the temperature sensed by the temperature sensor when the air blown by the hair dryer at different temperatures passes through the air duct of the air outlet part and the hand drying temperature at the initial distance is obtained through a large number of experiments, and then the first temperature difference is obtained through mathematical processing, such as mean value processing. In this way, when the temperature sensed by the temperature sensor is sensed, the hand drying temperature at the initial sensing distance is calculated by subtracting the first temperature difference from the sensed temperature.

[0087] In an example, the position information of the temperature sensor includes a distance between the temperature sensor and an outlet of the air duct, and the hand drying temperature at the initial sensing distance is calculated according to the temperature sensed by the temperature sensor and the position information of the temperature sensor, including:

[0088] The hand drying temperature at the initial sensing distance S1 is calculated by the following formula:

[0089]

[0090] wherein X1 is the initial sensing distance, X2 is the distance between the temperature sensor and the outlet of the air duct, S2 is the temperature sensed by the temperature sensor, and P and Q are respectively a first temperature compensation coefficient and a first temperature compensation value set in advance.

[0091] The method for obtaining the hand drying sensing distance provided by the embodiments considers the influence of different position information of the temperature sensor on the estimation of the hand drying temperature at the initial sensing distance, so that the estimated hand drying temperature at the initial sensing distance is more reasonable. Meanwhile, the temperature compensation coefficient is used as a multiplication coefficient, and the temperature compensation value is used as an addition coefficient to jointly correct the hand drying temperature at the initial sensing distance, so that the estimated hand drying temperature at the initial sensing distance is more reasonable.

[0092] In an example, the target sensing distance is obtained according to the comparison result, including:

[0093] In response to the hand drying temperature S1 at the initial sensing distance being greater than the target hand drying temperature S3, the initial sensing distance is adjusted to the target sensing distance X3 by the following formula:

[0094] X3=K*S1+B;

[0095] wherein K and B are respectively a second temperature compensation coefficient and a second temperature compensation value set in advance.

[0096] In an example, the target sensing distance is determined according to the temperature sensed by the temperature sensor and the target hand drying temperature, including:

[0097] The target sensing distance is determined according to the temperature sensed by the temperature sensor, the target hand drying temperature and the position information of the temperature sensor.

[0098] The hand drying sensing distance acquisition method provided by the embodiments of the present application considers the influence of different setting position information of the temperature sensor on the estimation of the hand drying temperature at the initial sensing distance when the hand dryer is directly triggered to start by some other way instead of the initial sensing distance, so that the estimated hand drying temperature at the initial sensing distance is more reasonable.

[0099] In an example, the setting position information of the temperature sensor includes a distance between the temperature sensor and the air outlet of the air duct, and the target sensing distance is determined according to the temperature sensed by the temperature sensor, the target hand drying temperature and the setting position information of the temperature sensor, including:

[0100] The target sensing distance X3 is determined by the following formula:

[0101]

[0102] wherein S3 is the target hand drying temperature, S2 is the temperature sensed by the temperature sensor, W and V are respectively a third temperature supplement coefficient and a third temperature compensation value set in advance, and X2 is the distance between the temperature sensor and the air outlet of the air duct.

[0103] The hand drying sensing distance acquisition method provided by the embodiments of the present application considers the influence of different setting position information of the temperature sensor on the determination of the target sensing distance, so that the determined target sensing distance is more reasonable. Meanwhile, the temperature supplement coefficient is used as a multiplication coefficient, and the temperature compensation value is used as an addition coefficient to jointly correct the target sensing distance, so that the determined target sensing distance is more reasonable.

[0104] In an example, the hand dryer base further includes a signal transmitter and a signal receiver arranged on the air duct, and the signal transmitter and the signal receiver are arranged in a central symmetry with respect to the central axis of the air duct; the air outlet of the hair dryer is arranged in the air duct to respond in the following manner:

[0105] A signal transmission instruction is sent to the signal transmitter, and a signal receiving result of the signal receiver is acquired.

[0106] It is judged whether the signal receiving result is empty, and in response to the judgment result that the signal receiving result is empty, it is determined that the air outlet of the hair dryer is arranged in the air duct.

[0107] The signal transmitter and the signal receiver are centrally symmetrically arranged relative to the central axis of the air duct, and the signal transmitter and the signal receiver are signal transmitters and signal receivers that realize the following function: the signal emitted by the signal transmitter can be received by the signal receiver without obstruction. The lengths of the air outlets of different types of hair dryers are different, and therefore, in order to realize the response of the air outlet of all types of hair dryers to the air duct, the signal transmitter and the signal receiver can be arranged close to the air inlet of the air duct, and when the air outlet of any type of hair dryer is arranged in the air duct, the signal emitted by the signal transmitter is blocked by the air outlet and cannot be received by the signal receiver, thereby realizing the response of the air outlet of the hair dryer to the air duct.

[0108] In actual application, the signal transmitter can be an infrared signal transmitter, and the signal receiver can be an infrared signal receiver.

[0109] In Figure 3 Based on the corresponding hair dryer, the application also provides a hair dryer base, as shown in Figure 6 The hair dryer base further comprises a signal transmitter 306 and a signal receiver 307 arranged on the air duct, the signal transmitter 306 and the signal receiver 307 are centrally symmetrically arranged relative to the central axis of the air duct, and the control device 304 is electrically connected to the signal transmitter 306 and the signal receiver 307.

[0110] The control device 304 is further configured to send a signal emission instruction to the signal transmitter 306, acquire a signal receiving result of the signal receiver 307, judge whether the signal receiving result is empty, and determine that the air outlet of the hair dryer is arranged in the air duct in response to a judgment result that the signal receiving result is empty.

[0111] In the hair dryer, the hair dryer is turned on by long pressing for 1 second, the double-lamp flashes three times, and the infrared pair tube of the air duct senses whether the hair dryer is placed. When the hair dryer is placed, the hair dryer light is always white, the hand is placed at the infrared sensing position S1 of the bottom of the hair dryer, the hair dryer works to blow air, the hair dryer light breathes and flashes, the hand is removed to stop, if there is always an obstruction, the hair dryer continues to work, and if more than three minutes, the hair dryer stops working, and the hair dryer can continue to work after the infrared sensing is triggered again. When the hair dryer is not placed, the hair dryer light is always white, the button is short pressed, the hair dryer is started, and the hair dryer light breathes and flashes. The hair dryer needs to be in a normal open state, and the hair dryer socket is plugged into a two-hole socket. The main control board controls the work of the hair dryer by controlling the on-off of the socket power supply. The hair dryer is installed on the bottom plate of the bathroom cabinet, the bottom plate is grooved, and the sensing module is exposed. The decorative cover is connected to the hair dryer through buckling, and the groove is hidden in the unsealed wood structure.

The hand sensing distance acquisition program can be divided into a plurality of devices, modules or units, and the plurality of devices, modules or units can be executed by the processor to realize the steps of the hand sensing distance acquisition method.

[0118] For example, the hand sensing distance acquisition program can be divided into an acquisition unit and a control unit, as shown in Figure 9 The acquisition unit 41 acquires the temperature sensed by the temperature sensor when the air blown by the hand dryer passes through the air duct, in response to the air outlet of the hand dryer being placed in the air duct and the hand dryer being in a working state.

[0119] The control unit 42 determines a target sensing distance for starting the hair dryer as a hand dryer according to the temperature sensed by the temperature sensor.
