Technical Field

[0001] The invention belongs to the field of air conditioners, and specifically provides an air conditioner and a control method thereof. Background Art

[0002] During the bathing process, water vapor often forms in the bathroom, causing discomfort to the human body. For this reason, most bathrooms are equipped with exhaust fans to exhaust the water vapor in the bathroom. However, if the user turns on the exhaust fan during the bathing process, the airflow formed by the exhaust fan will lower the user's body temperature, making the user feel colder, which will lead to a poor bathing experience for the user. Summary of the invention

[0003] One purpose of the present invention is to prevent the bathroom from fogging while ensuring the user's comfort in bathing.

[0004] A further object of the present invention is to determine whether the user is taking a bath.

[0005] To achieve the above object, the present invention provides a control method for an air conditioner in a first aspect, comprising:

[0006] Get the current ambient temperature M1 of the bathroom;

[0007] In response to the shower in the bathroom being turned on, obtaining the current water temperature M2 of the bath water;

[0008] Compare the current water temperature M2 with the current ambient temperature M1;

[0009] If M1 is less than M2, the air conditioner is controlled to start a heating mode to heat the bathroom.

[0010] Optionally, before obtaining the current water temperature M2 of the bath water, the control method further includes:

[0011] Acquiring infrared data in real time through the infrared temperature sensor on the air conditioner;

[0012] When the infrared data changes and the change amount of the infrared data reaches a preset value, it is determined that the shower is turned on.

[0013] Optionally, before obtaining the current water temperature M2 of the bath water, the control method further includes:

[0014] Acquiring the sound in the bathroom in real time through the sound pickup on the air conditioner;

[0015] The acquired sound is recognized, so as to determine that the shower head is turned on when the recognized sound includes the sound of the shower head spraying water.

[0016] Optionally, if M1 is less than M2, the step of controlling the air conditioner to start a heating mode to heat the bathroom includes:

[0017] If M1 is less than M2, determine whether the duration of obtaining the current water temperature M2 reaches a preset duration;

[0018] If the preset time is reached, the air conditioner is controlled to start a heating mode to heat the bathroom.

[0019] Optionally, if M1 is less than M2, the step of controlling the air conditioner to start a heating mode to heat the bathroom further includes:

[0020] If the preset time period is not reached, the air conditioner is controlled to maintain the current mode.

[0021] Optionally, after the step of controlling the air conditioner to start a heating mode, the control method further includes:

[0022] Determine whether the current ambient temperature M1 rises to the comfortable temperature M0;

[0023] If M1 reaches M0, the air conditioner is controlled to exit the heating mode.

[0024] Optionally, before the step of determining whether the current ambient temperature M1 has risen to the comfortable temperature M0, the control method further includes:

[0025] Get the identity information of the current bather;

[0026] The comfortable temperature M0 corresponding to the current bathing person is determined according to the identity information and a pre-stored identity information-comfortable temperature mapping table.

[0027] Optionally, the step of obtaining the identity information of the current bather includes:

[0028] Acquire the sound in the bathroom;

[0029] Identifying voiceprint information representing the original sound and the echo corresponding to the human voice from the sound;

[0030] The identity information of the current bather is determined according to the voiceprint information and a pre-stored voiceprint-user identity information mapping table.

[0031] Optionally, after the step of controlling the air conditioner to start a heating mode, the control method further includes:

[0032] If the speed of the fan of the air conditioner at the same gear is reduced by a preset speed, the air conditioner is controlled to start the exhaust mode, or the air conditioner is controlled to issue a command to turn on the exhaust fan of the bathroom to exhaust the bathroom.

[0033] In a second aspect, the present invention further provides an air conditioner, comprising a processor and a memory, wherein a machine executable program is stored in the memory, and when the processor executes the machine executable program, the control method described in any one of the first aspects can be implemented.

[0034] Based on the foregoing description, those skilled in the art will understand that, in the aforementioned technical solution of the present invention, by obtaining the current ambient temperature M1 of the bathroom, and obtaining the current water temperature M2 of the bath water when the shower in the bathroom is turned on; then comparing the current water temperature M2 with the current ambient temperature M1; when M1 is less than M2, controlling the air conditioner to turn on the heating mode to heat the bathroom, so that the air in the bathroom can be quickly heated by the air conditioner, thereby increasing the ambient temperature of the bathroom and reducing or even eliminating the formation of water mist by the hot air (water vapor) generated by the bath water.

[0035] Those skilled in the art can understand that water vapor in the air will liquefy into small water droplets when cooled, and thus form water mist. The present invention heats the bathroom through the air conditioner, so that the temperature of the air in the bathroom (i.e., the current ambient temperature M1) can quickly reach the current water temperature M2 of the bath water, thereby preventing the water vapor generated by the bath water from forming water mist when cooled.

[0036] Furthermore, the infrared data of the bathroom is obtained in real time through the infrared temperature sensor on the air conditioner. When the infrared data changes and the change amount of the infrared data reaches a preset value, it means that the shower is turned on and hot water is flowing out. At this time, it can be determined that the user is taking a shower. Alternatively, the sound in the bathroom is obtained in real time through the sound pickup on the air conditioner; and the obtained sound is recognized, so that when the recognized sound includes the sound of water spraying from the shower, it is determined that the shower is turned on and the user is taking a shower.

[0037] Furthermore, when M1 is less than M2, by determining whether the duration of obtaining the current water temperature M2 has reached a preset time, and when the preset time has been reached, the air conditioner is controlled to turn on the heating mode, thereby avoiding the user temporarily turning on the shower (which will not generate water mist, or the water mist will not cause discomfort to the user) and causing the air conditioner to turn on.

[0038] Furthermore, by acquiring the sound in the bathroom and identifying the voiceprint information representing the human voice from the sound, the identity information of the current bathing person is determined based on the voiceprint information and the pre-stored voiceprint-user identity information mapping table, so that the air conditioner can determine the specific value of the comfort temperature M0 according to different identity information, so as to ensure that the user's bathing water temperature is comfortable and that no water mist is generated in the bathroom.

[0060] like Figure 1 As shown, in one scenario of the present invention, the bathroom 100 is equipped with an air conditioner 200 capable of heating the bathroom 100, and the bathroom 100 also has a shower head 300 for the user to take a shower. Furthermore, the bathroom 100 may also be equipped with an exhaust fan 400, so that the air in the bathroom 100 is exhausted to the outside through the exhaust fan 400, or the outside air is sucked into the bathroom 100.

[0061] like Figure 2 As shown, in the present invention, the air conditioner 200 includes at least one of an infrared temperature sensor 210 and a sound pickup 220 .

[0062] The infrared temperature sensor 210 is used to detect the temperature of the bathroom 100, and when the shower head 300 is turned on, it can detect the temperature of the bath water sprayed by the shower head 300. For this purpose, the infrared temperature sensor 210 can be an infrared imager, or any feasible sensor such as a thermopile sensor. The contents related to the infrared temperature sensor 210 will be described in detail later in conjunction with the control method of the air conditioner 200.

[0063] The sound pickup 220 is used to pick up the sound in the bathroom 100, so that the air conditioner 200 can determine whether the shower 300 is turned on through the sound picked up by it; the sound picked up by the sound pickup 220 can also be identified to determine the identity information of the user who is currently taking a shower. For this purpose, the sound pickup 220 can be any feasible device such as a microphone. The content related to the sound pickup 220 will be described in detail later in conjunction with the control method of the air conditioner 200.

[0064] like Figure 2 As shown, in the present invention, the air conditioner 200 also includes conventional components such as a housing, a fan 230, and a heat exchanger. In addition, the air conditioner 200 also includes a processor 240 and a memory 250, and the memory 250 stores a machine executable program 251. When the processor 240 executes the machine executable program 251, it can implement the control method described in any of the embodiments below.

[0065] The memory 250 may include a memory and a non-volatile memory, and provide execution instructions and data to the processor 240. For example, the memory may be a high-speed random access memory (RAM), and the non-volatile memory may be at least one disk storage.

[0066] In this embodiment, the processor 240 is an integrated circuit chip that has the ability to process signals. The processor 240 can be a general-purpose processor, such as a central processing unit (CPU), a network processor (NP), a digital signal processor (DSP), an application specific integrated circuit (ASIC), a field programmable gate array (FPGA) or other programmable logic devices, discrete gate or transistor logic devices, discrete hardware components, microprocessors, and any other conventional processors.

[0067] Refer to the following Figures 3 to 13 The control method of the air conditioner 200 in the present invention is illustrated by way of example.

[0068] like Figure 3 As shown, in the first embodiment of the present invention, the control method of the air conditioner 200 includes:

[0069] Step S110 , obtaining the current ambient temperature M1 of the bathroom 100 .

[0070] In this embodiment, the air conditioner 200 can obtain the current ambient temperature M1 of the bathroom 100 in real time through the temperature sensor thereon.

[0071] The temperature sensor may be any feasible sensor, such as a resistive temperature sensor, an infrared temperature sensor 210 (such as Figure 2 shown) etc.

[0072] Step S120 , in response to the shower head 300 in the bathroom 100 being turned on, obtaining the current water temperature M2 of the bath water.

[0073] In the embodiment, the air conditioner 200 can detect the current water temperature M2 of the bath water through the temperature sensor thereon, and can also obtain the current water temperature M2 of the bath water by communicating with the shower head 300 .

[0074] For example, the air conditioner 200 can be operated by the above-described Figure 2 The infrared temperature sensor 210 shown in the figure is used to detect the current water temperature M2 of the bath water.

[0075] For this point, we will refer to Figure 5 The corresponding description will be given in conjunction with the second embodiment.

[0076] Step S130, comparing the current water temperature M2 with the current ambient temperature M1, and when M1<M2, executing step S140; when M1≥M2, keeping the air conditioner 200 in the current state.

[0077] Step S140 , if M1 is less than M2 , control the air conditioner 200 to start the heating mode to heat the bathroom 100 .

[0078] like Figure 4 As shown, in this embodiment, step S140 may further include:

[0079] Step S141: if M1 is less than M2, determine whether the duration of obtaining the current water temperature M2 reaches a preset duration.

[0080] The preset duration may be any feasible duration, such as 10 seconds, 30 seconds, 60 seconds, 90 seconds, etc.

[0081] Furthermore, in this embodiment, when it is detected that the shower head 300 is turned on, the timing can be started.

[0082] Step S142 , if the preset time is reached, control the air conditioner 200 to start the heating mode to heat the bathroom 100 .

[0083] Those skilled in the art can understand that when the duration of the air conditioner 200 continuously obtaining the current water temperature M2 of the bath water reaches a preset time, it means that the shower head 300 has been turned on for the preset time, indicating that the user is taking a bath, not temporarily using the shower head 300. At this time, the air conditioner 200 is controlled to turn on the heating mode, which avoids the user temporarily turning on the shower head 300 (no water mist will be generated, or the water mist will not cause discomfort to the user), which causes the air conditioner 200 to turn on.

[0084] Accordingly, if the result of executing step S141 is that the preset time period has not been reached, the air conditioner 200 is controlled to maintain the current mode.

[0085] Based on the foregoing description, those skilled in the art will understand that since water vapor in the air liquefies into small water droplets when cooled, thereby forming water mist; therefore, the present invention heats the bathroom 100 through the air conditioner 200 so that the temperature of the air in the bathroom 100 (i.e., the current ambient temperature M1) can quickly reach the current water temperature M2 of the bath water, thereby preventing the water vapor generated by the bath water from forming water mist when cooled.

[0086] It should be noted that the above-mentioned embodiment of the present invention is only a basic embodiment of the present invention. In other embodiments of the present invention, those skilled in the art may also adjust, optimize and configure the schemes and steps in the above-mentioned embodiments as needed to achieve further technical effects. Other embodiments of the present invention different from the above-mentioned embodiments will be described in conjunction with the accompanying drawings hereinafter. Of course, those skilled in the art may also make appropriate modifications to the execution order, operating conditions and quantity of the steps in the embodiments to be described hereinafter according to actual needs. The modified embodiments do not deviate from the technical concept and / or technical principle of the present invention and should still fall within the scope of protection of the present invention.

[0087] like Figure 5 As shown, in the second embodiment of the present invention, compared with the first embodiment described above, the control method of the air conditioner 200 further includes step S210 and step S220 located before step S120.

[0088] Wherein, step S210 includes, through the infrared temperature sensor 210 (such as Figure 2 As shown) to acquire infrared data in real time.

[0089] In this embodiment, the area detected by the infrared temperature sensor 210 includes all areas where the shower head 300 can be moved when the user is taking a shower. Therefore, when the shower head 300 is turned on, the infrared temperature sensor 210 can detect the temperature of the hot water sprayed from the shower head 300. Since the temperature of the hot water sprayed from the shower head 300 is significantly higher than the current ambient temperature M1 of the bathroom 100, when the shower head 300 just sprays hot water, the infrared temperature sensor 210 detects that the infrared data will suddenly change. That is, when the shower head 300 just sprays hot water, the infrared temperature sensor 210 detects that the temperature of a certain area will suddenly rise.

[0090] Wherein, step S220 includes, when the infrared data changes and the change amount of the infrared data reaches a preset value, determining that the shower head 300 is turned on.

[0091] Among them, the preset value can be any feasible value, for example, it can be the value of the infrared data corresponding to 3°C, the value of the infrared data corresponding to 5°C, the value of the infrared data corresponding to 10°C, the value of the infrared data corresponding to 123°C, etc.

[0092] Specifically, when the infrared temperature sensor 210 detects a sudden change in the infrared data, the current infrared data is subtracted from the infrared data at the previous moment. When the difference reaches a preset value, it indicates that there is an obviously high temperature in the bathroom 100. The high temperature is likely to be the hot water sprayed by the shower head 300. At this time, it can be determined that the shower head 300 is turned on.

[0093] Based on the foregoing description, those skilled in the art will appreciate that, in this embodiment, the air conditioner 200 can actively detect that the user is taking a shower through the infrared temperature sensor 210, thereby making the air conditioner 200 more intelligent and improving the user's life experience.

[0094] like Figure 6 As shown, in the third embodiment of the present invention, compared with the first embodiment described above, the control method of the air conditioner 200 further includes step S310 and step S320 located before step S120.

[0095] Wherein, step S310 includes, through the sound pickup 220 (such as Figure 2 As shown) the sound inside the bathroom 100 is acquired in real time.

[0096] Wherein, step S320 includes recognizing the acquired sound, so as to determine that the shower head 300 is turned on when the recognized sound includes the sound of the shower head 300 spraying water.

[0097] Specifically, the sound collected by the sound pickup 220 is analyzed in real time to determine whether it contains the same or similar voiceprint information in the voiceprint library. If it does, it is determined that the shower head 300 is turned on.

[0098] Among them, the voiceprint library corresponds to the sound of shower water sprayed by various sprinklers 300 at various water pressures, various heights, and various modes, which are pre-stored on the air conditioner 200 or on a cloud server, background server, or other intelligent terminal device that is connected to the air conditioner 200 for communication.

[0099] This embodiment has the same technical effects as the second embodiment, and will not be described in detail here.

[0100] like Figure 7 As shown, in the fourth embodiment of the present invention, compared with any of the embodiments described above, the control method of the air conditioner 200 further includes step S410 and step S420 located after step S140.

[0101] Wherein, step S410 includes determining whether the current ambient temperature M1 rises to the comfortable temperature M0.

[0102] The comfortable temperature M0 is higher than the current body temperature of the person taking a bath, and can be any feasible value based on this, such as 37°C, 38°C, 40°C, 41°C, 43°C, 45°C, etc.

[0103] In an embodiment, the comfort temperature M0 may be pre-stored in the air conditioner 200, or may be set by the user through a terminal device such as a remote control or a mobile phone that can control the air conditioner 200, or may be a value set by the air conditioner 200 according to the current bathing temperature.

[0104] When the comfortable temperature M0 is a value set by the air conditioner 200 according to the current bathing temperature, M0=M2+d, where d is 1°C, 2°C, 3°C, 5°C, etc.

[0105] Wherein, step S420 includes, if M1 reaches M0, controlling the air conditioner 200 to exit the heating mode.

[0106] Correspondingly, if the result of executing step S420 is that M1 is less than M0, the air conditioner 200 is controlled to maintain the current mode and continue to heat the bathroom 100.

[0107] Based on the foregoing description, those skilled in the art will appreciate that this embodiment enables the air conditioner 200 to automatically stop heating after the bathroom 100 reaches a suitable temperature, which is more intelligent.

[0108] like Figure 8As shown, in the fifth embodiment of the present invention, compared with the fourth embodiment described above, the control method of the air conditioner 200 further includes step S510 and step S520 located before step S410.

[0109] Wherein, step S510 includes obtaining the identity information of the current bather.

[0110] Optionally, the air conditioner 200 is provided with a camera so that the air conditioner 200 can recognize the identity information of the person taking a bath in front by using the face recognition technology through the camera.

[0111] Alternatively, if Fig. 9 As shown, step S510 may also include:

[0112] Step S511 , obtaining the sound in the bathroom 100 .

[0113] Specifically, the sound pickup 220 (such as Figure 2 As shown) captures the sound inside the bathroom 100.

[0114] Step S512: identifying voiceprint information representing a human voice from the sound.

[0115] Step S513: according to the voiceprint information and the pre-stored voiceprint-user identity information mapping table (such as Fig.10 As shown), determine the identity information of the current bathing person.

[0116] For example, if the voiceprint information identified in step S512 is C (such as Fig.10 As shown), the identity information of the current bather determined in step S513 is 3 (as shown Fig.10 shown).

[0117] It should be noted that in the present invention Fig.10 and Fig.12 The mapping table shown is only for illustrating the mapping relationship between two corresponding objects, and the specific values ​​between the two corresponding objects can be obtained through multiple experiments.

[0118] like Fig.11 As shown, step S510 may further include the following steps between step S512 and step S513:

[0119] Step S514: if there are multiple voiceprint information representing human voice, all voiceprint information corresponding to the original sound and the echo are determined.

[0120] The original sound is the sound emitted by the user, and the echo is the sound of the user reflected by the wall.

[0121] Those skilled in the art should know that the echo formed by the wall reflecting the original sound does not change the voiceprint information.

[0122] Step S515: If the determined voiceprint information is one, the one voiceprint information is used as the final voiceprint information for execution in step S513.

[0123] Step S516: If the determined voiceprint information is at least two, determine the interval between the original sound and the echo corresponding to each voiceprint information.

[0124] Step S517, comparing the lengths of the intervals, and taking the voiceprint information corresponding to the smallest interval as the final voiceprint information for execution in step S513.

[0125] Those skilled in the art can understand that steps S514 to S517 can avoid interference of other sound sources on the execution result of the entire solution, thereby ensuring the reliability of the execution result of the solution.

[0126] Wherein, step S520 includes, according to the identity information and the pre-stored identity information-comfort temperature mapping table (such as Fig.12 As shown), determine the comfortable temperature M0 corresponding to the current bathing person.

[0127] For example, the identity information of the current bather determined in step S510 (specifically step S513) is 3 (such as Fig.12 As shown), the comfortable temperature M0 determined in step S520 is 39°C (as shown Fig.12 shown).

[0128] Based on the foregoing description, those skilled in the art will appreciate that this embodiment enables the air conditioner 200 to automatically identify the user's identity information and configure a corresponding comfort temperature M0 for the user, thereby preventing the current bather's perceived temperature from being too high or too low, thereby improving the comfort of the previous bather.

[0129] like Fig.13 As shown, in the sixth embodiment of the present invention, compared with any of the embodiments described above, the control method of the air conditioner 200 further includes step S610 or step S620 after step S140.

[0130] Wherein, step S610 includes, if the speed of the fan 230 of the air conditioner 200 at the same gear is reduced by a preset speed, controlling the air conditioner 200 to start the exhaust mode to exhaust the air in the bathroom 100.

[0131] The preset speed may be any feasible speed, such as 20 r / min, 50 r / min, 85 r / min, 100 r / min, etc.

[0132] Furthermore, the preset speeds corresponding to the fan 230 at different gears may be the same or different. For example, the speed corresponding to the fan 230 at the high wind gear is 100 r / min, the speed corresponding to the fan 230 at the medium wind gear is 70 r / min, and the speed corresponding to the fan 230 at the low wind gear is 30 r / min.

[0133] For example, if the normal rotation speed of the fan 230 in the middle stroke position is 3000 r / min, when the current rotation speed of the fan 230 becomes 2850 r / min, the air conditioner 200 is controlled to start the exhaust mode.

[0134] Wherein, step S620 includes, if the speed of the fan 230 of the air conditioner 200 at the same gear is reduced by a preset speed, controlling the air conditioner 200 to issue an instruction to turn on the exhaust fan 400 of the bathroom 100 to exhaust the bathroom 100.

[0135] In step S620 , the air conditioner 200 is communicatively connected with the exhaust fan 400 so that the air conditioner 200 can send a start instruction to the exhaust fan 400 .

[0136] For example, the air conditioner 200 is provided with a signal transmitter (such as an infrared signal transmitter), and the exhaust fan 400 is provided with a signal receiver (such as an infrared signal receiver). The air conditioner 200 can transmit an on or off instruction to the exhaust fan 400 through the signal transmitter thereon. When the exhaust fan 400 receives the on or off instruction sent by the air conditioner 200 through its signal receiver, it starts or ends operation.

[0137] It is understood by those skilled in the art that as the user's bathing time increases, the heat in the room increases, the air expands, and the air pressure increases. At the same time, the water vapor flowing out of the shower head 300 increases the specific gravity of the air, causing the load of the fan 230 to increase. Both of these situations will cause the speed of the fan 230 to decrease. At this time, exhausting the air in the bathroom 100 can restore the bathroom 100 to its original environment, ensuring the comfort of the current bather.
