[0042] In the related art, the bathroom cabinet hand dryer currently on the market uses the existing hair dryer as a hand dryer. When used as a hair dryer, it can be used for blowing hair. When it is idle, it can be used as a hand dryer with the help of the hand dryer base and infrared tube sensing. Figure 1 As shown, the hair dryer 11 is placed on the hand dryer base 12 and used as a hand dryer. When used as a hand dryer, the decorative cover 13 on the hand dryer base is removed, so that the wind of the hair dryer is blown out from the air cylinder in the hand dryer base, and the hand dryer performs the hand drying function.

[0043] The hair dryer that can be used with the hand dryer base can be of different types. Different types of hair dryers have different blowing principles, and the wind speed and blowing temperature are also different. Therefore, the temperature is also different when used as a hand dryer.

[0044] However, in the related art, the infrared sensing distance is fixed. Therefore, when the temperature of the hair dryer itself is high, the temperature felt by the user at the fixed sensing distance is also correspondingly high, and the user feels poorly.

[0045] To this end, an embodiment of the present application provides a method for obtaining a hand drying sensing distance, which is applied to a hand drying base, wherein the hand drying base comprises: a wind tube having an air outlet, and a temperature sensor disposed on the wind tube, such as Figure 2 As shown, the method includes:

[0046] Step 201: in response to an air outlet of the hair dryer being placed in the air cylinder and the hair dryer being in working state, obtaining a temperature sensed by the temperature sensor when the air blown by the hair dryer passes through the air cylinder from the air outlet;

[0047] Step 202, determining a target sensing distance for starting the hair dryer for use as a hand dryer 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 hair dryer.

[0049] The hand dryer base in the hand dryer sensing distance acquisition method provided in the embodiment of the present application can be as follows Figure 3 As shown, it includes the following structures: a main body 301 , a wind tube 302 with an air outlet arranged on the main body 301 , a temperature sensor 303 arranged on the wind tube 302 , and a control device 304 arranged on the main body 301 .

[0050] A temperature sensor 303, configured to sense the temperature when the wind blown by the hair dryer passes through the wind tube 302 from the wind 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 for use as a hand dryer according to the temperature sensed by the temperature sensor 303 .

[0052] The temperature sensor can be arranged under the blowing path of the wind blown by the hair dryer passing through the wind tube from the wind outlet. When the hair dryer blows, the wind blown by the hair dryer passes through the temperature sensor in the process of passing through the wind tube from the wind outlet, and the temperature sensor performs temperature sensing. In order to better sense the temperature of the wind, the temperature sensor can be arranged on the inner wall of the wind tube, and the specific position can be arranged at a position close to the side of the wind outlet facing the wind outlet and far from the wind outlet, or it can be arranged at a position far from the side of the wind outlet facing the wind outlet and close to the wind outlet. When the specific position of the temperature sensor is close to the side of the wind outlet facing the wind outlet and far from the wind outlet, the wind blown by the hair dryer can reach the temperature sensor after a short distance, so the temperature loss is small, and the temperature sensed by the temperature sensor is high. When the specific position is far from the side of the wind outlet facing the wind outlet and close to the wind outlet, the wind blown by the hair dryer needs to travel 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 to be used as a dryer using the target sensing distance. When the hair dryer is used as a hand dryer, the hair dryer gear must be in a normally open state, and the hair dryer socket is plugged into a two-hole socket. The control device controls the operation of the hair dryer by controlling the on and off of the power supply of the socket, or the control device controls the main control board in the hand dryer base to control the on and off of the power supply of the socket to control the operation of the hair dryer.

[0054] In an exemplary embodiment, determining a target sensing distance for starting the hair dryer to be used as a hand dryer according to the temperature sensed by the temperature sensor includes:

[0055] Calculating the hand drying temperature at a preset initial sensing distance according to the temperature sensed by the temperature sensor, and adjusting the initial sensing distance to obtain the target sensing distance by comparing with the target hand drying temperature; wherein the initial sensing distance is a sensing distance preset for initially starting the hair dryer as a hand dryer;

[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 a pre-obtained correspondence 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 dryer, it can be achieved in the following ways:

[0059] First, an initial sensing distance for initially starting the hair dryer as a hand dryer is set, and then the hand dryer is triggered to start according to the initial sensing distance, and the temperature sensor senses the temperature, 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] This can also be achieved by:

[0061] The hand dryer is not triggered to start by setting an initial sensing distance, but is directly triggered to start initially by other means. However, the target sensing distance is determined according to the temperature sensed by the temperature sensor and the target hand drying temperature.

[0062] This can also be achieved by:

[0063] The corresponding relationship between the sensing temperature and the sensing distance is obtained in advance through a large number of experiments, wherein the sensing temperature in the corresponding relationship refers to the temperature sensed by the temperature sensor when a hair dryer with different blowing temperatures is mounted on the hand dryer base and the air outlet is placed in the air dryer for blowing, and the sensing distance in the corresponding relationship refers to the sensing distance required to reach a preset target hand drying temperature under the conditions of different temperatures sensed by the sensor, and the sensing distance corresponding to each temperature sensed by the sensor can be obtained in the following manner: by moving from the air outlet of the air dryer in a direction away from the air dryer and measuring the temperature, and when the measured temperature reaches the target hand drying temperature, the distance moved is used as the sensing distance corresponding to the temperature sensed by the sensor.

[0064] The correspondence between the sensing temperature and the sensing distance obtained in advance can be stored as a table, so that after obtaining the temperature sensed by the temperature sensor, the corresponding target sensing distance can be directly obtained by table query, that is, the temperature when the wind blown by the hair dryer reaches the obtained target sensing distance is the target hand drying temperature.

[0065] In an exemplary embodiment, when the target sensing distance is obtained by calculating the hand drying temperature at the preset initial sensing distance according to the temperature sensed by the temperature sensor, and adjusting the initial sensing distance by comparing with the target hand drying temperature, the hand drying base further includes: a distance detection module, and the working state of the hair dryer is responded to in the following manner:

[0066] Acquire the sensing distance detected by the distance detection module;

[0067] The detected sensing distance is compared with the initial sensing distance, and in response to a comparison result that the detected sensing distance is less than or equal to the initial sensing distance, the hair dryer is started.

[0068] The hand dryer base in the hand dryer sensing distance acquisition method provided in the embodiment of the present application can be as follows Figure 4 As shown, the dryer comprises the following structures: a body 301, an air cylinder 302 with an air outlet arranged on the body 301, a temperature sensor 303 arranged on the air cylinder 302, a control device 304 arranged on the body 301 and a distance detection module 305 arranged on the base of the dryer.

[0069] A temperature sensor 303, configured to sense the temperature of the air blown by the hair dryer when the air passes through the air cylinder from the air outlet;

[0070] A distance detection module 305 is configured to detect a sensing 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 sensing distance detected by the distance detection module 305; compare the detected sensing distance with the initial sensing distance, and start the hair dryer in response to the comparison result that the detected sensing distance is less than or equal to the initial sensing distance; obtain the temperature sensed by the temperature sensor 303, and adjust the initial sensing distance to obtain the target sensing distance according to the comparison between the temperature sensed by the temperature sensor 303 and a preset target hand drying temperature.

[0072] The distance detection module can be set at the air outlet of the hair dryer, so that the distance detected by the distance detection module is the distance between the user's hand and the air outlet of the hair dryer; it can also be set at a position other than the air outlet of the hair dryer, so that the distance detected by the distance detection module needs to be subtracted from the distance between the distance detection module and the air outlet of the hair dryer, which is the distance between the user's hand and the air outlet of the hair dryer.

[0073] In practical applications, the distance detection module may be an infrared distance measuring module, and the distance measuring principle of the infrared distance measuring module is the reflection energy principle, that is, by emitting a beam of infrared light to illuminate the surface of the measured object, and receiving the reflected light energy of the measured object to determine the distance. Therefore, when measuring the distance with the help of the infrared distance measuring module, the infrared distance measuring module emits a beam of infrared light to illuminate 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 hair dryer.

[0074] In an exemplary embodiment, when the target sensing distance is obtained in a manner determined according to the temperature sensed by the temperature sensor and the target hand drying temperature, the hand drying base further includes: an instruction receiving module, and the working state of the hair dryer is responded to by:

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

[0076] The hair dryer is started according to the obtained hair dryer working instruction.

[0077] The hand dryer base in the hand dryer sensing distance acquisition method provided in the embodiment of the present application can be as follows Figure 5 As shown, it includes the following structures: a main body 301, a wind tube 302 with an air outlet arranged on the main body 301, a temperature sensor 303 arranged on the wind tube 302, a control device 304 arranged on the main body 301 and an instruction receiving module 306 arranged on the main body 301.

[0078] A temperature sensor 303, configured to sense the temperature of the air blown by the hair dryer when the air passes through the air cylinder from the air outlet;

[0079] The instruction receiving module 306 is configured to receive the blower operation instruction;

[0080] The control device 304 is electrically connected to 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, and 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 a preset target hand drying temperature.

[0081] The instruction receiving module can be a signal receiver. When the instruction receiving module is a signal receiver, the signal receiver receives the control signal sent by the user through the signal transmitter, and determines whether the instruction corresponding to the control signal is a hair dryer working instruction. When it is determined to be a 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, calculating the hand drying temperature at a preset initial sensing distance according to the temperature sensed by the temperature sensor, and adjusting the initial sensing distance to obtain the target sensing distance by comparing with the target hand drying temperature, comprises:

[0083] calculating the hand drying temperature at the initial sensing distance according to the temperature sensed by the temperature sensor and the setting position information of the temperature sensor; or calculating the hand drying temperature at the initial sensing distance according to the temperature sensed by the temperature sensor and a preset first temperature difference; or calculating the hand drying temperature at the initial sensing distance according to the temperature sensed by the temperature sensor and a preset first temperature difference coefficient;

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

[0085] The hand drying temperature at the initial sensing distance can be calculated based on the temperature sensed by the temperature sensor and the preset first temperature difference value by the following method: a large number of experiments are performed to obtain the 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 from the air outlet and the hand drying temperature at the initial distance, and then the first temperature difference is obtained by mathematical processing, such as taking the average value. In this way, when the temperature sensed by the temperature sensor is deducted from the first temperature difference, the hand drying temperature at the initial sensing distance is calculated.

[0086] The calculation of the hand drying temperature at the initial sensing distance according to the temperature sensed by the temperature sensor and the preset first temperature difference can be achieved in the following manner: a large number of experiments are performed to obtain the temperature sensed by the temperature sensor when the air blown by the hair dryer at different temperatures passes through the air duct from the air outlet and the hand drying temperature at the initial distance, and then mathematically processed, for example, the ratio of the hand drying temperature at the initial distance to the temperature sensed by the temperature sensor is calculated, and then the first temperature difference coefficient is obtained by averaging multiple ratio calculation results. In this way, when the temperature sensor senses the temperature, the hand drying temperature at the initial sensing distance is calculated by multiplying the sensed temperature by the first temperature difference coefficient.

[0087] In an exemplary embodiment, the setting position information of the temperature sensor includes: the distance between the temperature sensor and the air outlet of the air duct, and the calculating the hand drying temperature at the initial sensing distance according to the temperature sensed by the temperature sensor and the setting position information of the temperature sensor includes:

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

[0089]

[0090] Among them, X1 is the initial sensing distance, X2 is the distance between the temperature sensor and the air outlet of the wind tube, S2 is the temperature sensed by the temperature sensor, and P and Q are the preset first temperature compensation coefficient and first temperature compensation value respectively.

[0091] The method for obtaining the hand drying sensing distance provided in the embodiment of the present application takes into account the influence of different setting 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. At the same time, the temperature supplement coefficient is used as the multiplication coefficient, and the temperature compensation value is used as the 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 exemplary embodiment, adjusting the initial sensing distance according to the comparison result to obtain the target sensing distance includes:

[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] Among them, K and B are the preset second temperature compensation coefficient and second temperature compensation value.

[0096] In an exemplary embodiment, determining the target sensing distance according to the temperature sensed by the temperature sensor and the target hand drying temperature includes:

[0097] 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.

[0098] The method for obtaining the hand drying sensing distance provided in the embodiment of the present application takes into account 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 drying start is not triggered by setting the initial sensing distance but directly triggered by other methods. Therefore, the estimated hand drying temperature at the initial sensing distance is more reasonable.

[0099] In an exemplary embodiment, the setting position information of the temperature sensor includes: the distance between the temperature sensor and the air outlet of the air duct, and determining the target sensing distance according to the temperature sensed by the temperature sensor, the target hand drying temperature and the setting position information of the temperature sensor includes:

[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 preset third temperature supplement coefficient and a third temperature compensation value, 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 in the embodiment of the present application takes into account 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. At the same time, the temperature supplement coefficient is used as the multiplication coefficient, and the temperature compensation value is used as the addition coefficient to jointly correct the target sensing distance, so that the determined target sensing distance is more reasonable.

[0104] In an exemplary embodiment, the hand dryer base further comprises: a signal transmitter and a signal receiver disposed on the air cylinder, wherein the signal transmitter and the signal receiver are centrally symmetrically disposed relative to the central axis of the air cylinder; the air outlet of the hair dryer is disposed in the air cylinder to achieve response in the following manner:

[0105] Sending a signal transmission instruction to the signal transmitter and obtaining a signal reception result of the signal receiver;

[0106] It is determined whether the signal receiving result is empty, and in response to the determination result that the signal receiving result is empty, it is determined that the air outlet of the hair dryer is placed in the air cylinder.

[0107] The signal transmitter and the signal receiver are centrally symmetrically arranged relative to the central axis of the hair dryer, which means a signal transmitter and a signal receiver that realize the following functions: the signal emitted by the signal transmitter can be received by the signal receiver in the absence of obstruction. The lengths of the air outlets of different types of hair dryers are different. Therefore, in order to achieve the response of the air outlets of all types of hair dryers being placed in the hair dryer, the signal transmitter and the signal receiver can be arranged close to the air inlet of the hair dryer. When the air outlet of any type of hair dryer is placed in the hair dryer, the signal emitted by the signal transmitter can be blocked by the air outlet so as not to be received by the signal receiver, thereby achieving the response of the air outlet of the hair dryer being placed in the hair dryer.

[0108] In practical applications, the signal transmitter may be an infrared signal transmitter, and the signal receiver may specifically be an infrared signal receiver.

[0109] exist Figure 3 On the basis of the corresponding hand dryer, the embodiment of the present application also provides a hand dryer base, such as Figure 6 As shown, the hand dryer base further includes: a signal transmitter 306 and a signal receiver 307 arranged on the air cylinder, the signal transmitter 306 and the signal receiver 307 are centrally symmetrically arranged relative to the central axis of the air cylinder, and the control device 304 is electrically connected to the signal transmitter 306 and the signal receiver 307 respectively.

[0110] The control device 304 is also configured to send a signal transmission instruction to the signal 306 and obtain the signal reception result of the signal receiver 307; determine whether the signal reception result is empty, and in response to the judgment result that the signal reception result is empty, determine that the air outlet of the hair dryer is placed in the air cylinder.

[0111] When the hand dryer in the hand dryer sensing distance acquisition method provided in the embodiment of the present application is in use, long press for 1S to turn on the hand dryer, the double lights flash 3 times, and the hair dryer infrared pair tube senses whether the hair dryer is put in. If the hair dryer is put in, the hand dryer light is always bright white, and the hand is placed on the infrared sensing at the bottom S1 of the hand dryer. At this time, the hair dryer is working and blowing, and the hand dryer light is breathing and flashing. It stops when the hand is removed. If there is always an obstruction, it will continue to work. If it exceeds three minutes, it will stop working. It can continue to work after the hand is removed and the infrared sensing is triggered again. If the hair dryer is not put in, the hair dryer light is always bright white, short press the button, the hair dryer starts, and the blowing indicator light is breathing and flashing. The hair dryer gear must be in the normally open state, and the hair dryer socket is plugged into a two-hole socket. The main control board controls the operation of the hair dryer by controlling the on and off of the socket power supply. The hand dryer is installed on the bottom plate of the bathroom cabinet, and the bottom plate is grooved to expose the sensing module.
