Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the technical solutions of the present invention will be clearly and completely described below with reference to the specific embodiments of the present invention and the accompanying drawings. It is to be understood that the described embodiments are merely exemplary of the invention, and not restrictive of the full scope of the invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

According to an embodiment of the present invention, a hand-pinching prevention control device is provided, as shown in fig. 1, which is a schematic structural diagram of an embodiment of the hand-pinching prevention control device of the present invention. This prevent tong controlling means can include: a microwave sensor 3, a photoelectric switch 4 and a controller 5.

In an optional example, the microwave sensor 3 may be configured to acquire, within a detection range of the microwave sensor, a first detection signal indicating whether a human body is close to the air outlet panel 2 of the air conditioner 1 to be controlled.

For example: a microwave sensor is adopted, and Doppler effect is applied to detect whether a human body approaches.

Optionally, the microwave sensor 3 is located below the air outlet panel 2 of the air conditioner 1 and is installed inside or outside the complete machine panel of the air conditioner 1.

For example: the microwave sensor is installed below the air outlet panel and can be placed inside or on the surface of the air conditioner panel, as shown in fig. 2.

From this, through setting up the microwave sensor in the below of the air-out panel of air conditioner and installing in the inside or the outside of the complete machine panel of air conditioner, be favorable to promoting and detect accurate nature, and then promote the security of preventing pressing from both sides the reliability of hand control and user's use.

Optionally, the microwave sensor 3 is connected to the controller 5.

For example: the microwave sensor is connected with the air conditioner controller through a lead to transmit signals.

Therefore, the microwave sensor is connected with the controller of the air conditioner for signal transmission, and the reliability and safety of signal transmission are guaranteed.

Optionally, the detection range of the microwave sensor 3 may include: and detecting at least one of an angle and a distance.

The detection range of the microwave sensor 3 may be configured to adjust at least one of the detection angle and/or the detection distance by adjusting at least one of the number of the microwave sensors 3, the power of any one of the one or more microwave sensors 3, and the installation position of any one of the one or more microwave sensors 3 according to an actual detection requirement.

For example: fig. 3 is a schematic diagram of the detection area of the sensor, and the specific detection range (e.g., angle, distance, etc.) can be adjusted according to actual needs. For example: the specific angle range can be 0-360 degrees, the emission angle of the microwave sensor can be changed by adjusting the angle of the structure, and a plurality of sensors are required to be installed around the air conditioner if the effect of 360 degrees is achieved. According to the actual needs, objects in certain ranges need to be detected for adjustment according to the development requirements of products, for example, 0-135 degrees shown in fig. 3, or objects within 0-180 degrees need to be detected by other products, the angle and distance can be changed by adjusting the power of the sensor and adjusting the structure for mounting the sensor.

Therefore, the detection area of the microwave sensor is flexibly adjusted according to the detection requirement, the accuracy and the reliability of anti-pinch control by utilizing the microwave sensor can be improved, the application range is wide, and the adjustment flexibility is good.

Optionally, the microwave sensor 33 may include: the microwave transmitting tube and the microwave receiving tube.

The microwave transmitting tube can be used for transmitting microwave signals with set waveforms. The microwave receiving tube can be used for receiving a reflection signal of the microwave signal from a human body in the detection range, and the reflection signal has the same waveform with the microwave signal.

For example: the microwave sensor can adopt a combined mode of an infrared transmitting tube and an infrared receiving tube. The infrared transmitting tube transmits infrared light, if someone is in front of the sensor, the infrared light is subjected to diffuse reflection, and the receiving tube receives infrared signals.

From this, whether detect the air-out panel that the human body is close to the air conditioner through microwave transmitting tube and microwave receiving tube complex mode, the accurate nature that detects is good, is favorable to promoting the reliability and the security of preventing pressing from both sides hand control.

In an optional example, the photoelectric switch 4 may be configured to obtain a second detection signal indicating whether a pinching phenomenon occurs at the air outlet panel 2 of the air conditioner.

Optionally, the photoelectric switch 4 is disposed above or below the air outlet panel 2 of the air conditioner 1.

From this, through setting up photoelectric switch in the air-out panel department of air conditioner, be favorable to guaranteeing accurate nature and the promptness that the tong detected.

In an optional example, the controller 5 may be configured to control the operation of the air conditioner 1 according to the first detection signal and the second detection signal, so as to implement the hand pinching prevention control. For example: the controller 5 may be a controller of the air conditioner itself.

For example: whether a human body approaches the equipment is detected by using a Doppler microwave sensor, and the specific operation mode of the moving part and the control method of the controller are judged according to whether a person approaches the equipment.

For example: the problem that the air outlet grille clamping hand of the cabinet air conditioner is painful is solved by jointly judging through the combination of the photoelectric switch and the microwave sensor, and the aim of normally protecting the machine from being stopped can be fulfilled when the real structural member of the air conditioner is clamped to cause the motor to be locked.

From this, prevent pressing from both sides the hand control through combining photoelectric switch and microwave sensor, can alleviate the painful sense of pressing from both sides the hand, and can guarantee that the air conditioner just normally protects when appearing real structure and block and lead to the motor stall to shut down, reduce shutdown frequency, promote user experience.

In an optional example, the acquiring, by the microwave sensor 3, a first detection signal of whether a human body approaches the air outlet panel 2 of the air conditioner 1 to be controlled may include: if the microwave receiving tube receives the reflected signal, the first detection signal indicates that the human body is close to the air outlet panel 2; if the microwave receiving tube does not receive the reflected signal, the first detection signal indicates that no one is close to the air outlet panel 2.

For example: when the microwave sensor can adopt a combined mode of an infrared transmitting tube and an infrared receiving tube, if the receiving tube receives a signal, the front of the microwave sensor is judged to be occupied, and if the receiving tube does not receive the signal, the front of the air conditioner is judged to be unoccupied.

For example: the infrared transmitting tube transmits infrared light with specific waveform, error correction measures are added in the program to process the signal, the receiving tube receives the same waveform, the signal is judged to be correct, otherwise, the signal is judged to be interference signal, and no processing is carried out. For example: according to the characteristics of the transmission and the reception of the sensor, the successful reception is considered after receiving the continuous low level within a certain time limit, and the error correction measures are to correct the error on the received low level, the time is continuous, and the continuous low level time is in a required range. Wherein, in order to prevent the false action, only after detecting the above-mentioned signal for N times continuously, regard as really valid, otherwise judge as the invalid signal; if an unsatisfactory signal occurs within N times, the clear 0 starts counting N times again.

Therefore, whether a human body is close to the air outlet panel of the air conditioner or not is determined by whether the reflected signal is received or not, the detection mode is simple and convenient, and the detection accuracy is good.

Further, the controller 5 controls the operation of the air conditioner 1, and may include: if the first detection signal indicates that no person approaches the air outlet panel 2, setting the hand clamping time at the air outlet panel 2 as a first hand clamping time, and enabling the air sweeping mechanism of the air conditioner 1 to normally operate; if the first detection signal indicates that the human body is close to the air outlet panel 2, the hand clamping time at the air outlet panel 2 is set as a second hand clamping time. The second clamping time is less than the first clamping time and is greater than the detection time of the photoelectric switch 4 for detecting the set level.

For example: when the microwave sensor detects that no person approaches, the time of clamping the hands is k seconds; when detecting that the human body is close to the air conditioner, reduce tong time (k second-x second) to alleviate the painful sense that the tong caused, improve the security performance of air conditioner, can promote to prevent tong function and experience, alleviate tong painful sense.

For example: when a lower sensor (e.g., a microwave sensor) detects that no one is approaching, the wind sweeping is performed according to normal functional logic.

From this, reduce tong time when detecting the air-out panel that the human body is close to the air conditioner at microwave sensor to can alleviate tong pain and feel when the tong is experienced, improve tong and experience.

In an optional example, the acquiring, by the photoelectric switch 4, the second detection signal of whether the pinching phenomenon occurs at the air outlet panel 2 of the air conditioner 1 may include: under the condition that the first detection signal is unmanned and close to the air outlet panel 2, if the photoelectric switch 4 continuously detects the set level within a first set time and/or the number of times that the photoelectric switch 4 detects the set level is a first set number of times, and the duration of the set level is a first hand clamping time, the second detection signal indicates that the structural member is clamped at the air outlet panel 2.

Or, the photoelectric switch 4 obtains a second detection signal whether the air outlet panel 2 of the air conditioner 1 has a hand clamping phenomenon, and may further include: under the condition that the first detection signal is that the human body approaches the air outlet panel 2 and the detection function of the microwave sensor 3 is not shielded, if the number of times that the photoelectric switch 4 continuously detects the set level within the second set time is the second set number of times, the second detection signal is that the second set number of times occurs at the air outlet panel 2 and the second hand-clamping time lasts each time.

From this, detect the time and the number of times of tong through photoelectric switch, confirm that air conditioner air-out panel department whether the structure blocks or the tong phenomenon appears, detect that the precision is good, the reliability is high.

Further, the method can also comprise the following steps: an alarm. The controller 5 controls the operation of the air conditioner 1, and may further include: if the second detection signal indicates that the structural part is clamped at the air outlet panel 2, starting the alarm to initiate fault reminding, and stopping the whole air conditioner 1; if the second detection signal indicates that the air outlet panel 2 has a second set number of times and a second hand clamping phenomenon lasts for a second hand clamping time each time, the air sweeping mechanism of the air conditioner 1 is made to reversely rotate for a set angle and then continues to sweep air.

For example: when a lower sensor (such as a microwave sensor) detects that no one approaches, wind sweeping is executed according to normal function logic, after hands are clamped for m times and k seconds each time, an FC fault needs to be reported to stop the whole machine from running, so that when a real structural part is clamped, the whole machine is started to run again when wind sweeping cannot be started, and potential safety hazards are caused.

Therefore, the safety of the air conditioner can be ensured by alarming and stopping the air conditioner when the structural member is clamped at the air outlet panel of the air conditioner; when the hand clamping is determined to occur, the air sweeping mechanism is enabled to rotate reversely without stopping, on one hand, the hand clamping phenomenon can be treated, on the other hand, the normal operation of the air conditioner is not influenced, and the user experience is good.

In an optional example, the acquiring, by the photoelectric switch 4, a second detection signal of whether a pinching phenomenon occurs at the air outlet panel 2 of the air conditioner 1 may further include: under the condition that the air sweeping mechanism of the air conditioner 1 continues to sweep air after reversing the set angle, if the number of times that the photoelectric switch 4 continuously detects the set level is a third set number of times, the second detection signal is a hand clamping phenomenon that the third set number of times appears at the air outlet panel 2 and the second hand clamping time lasts each time.

Therefore, the air conditioner continues to detect after the air sweeping mechanism of the air conditioner reverses, whether the hand clamping phenomenon can be processed or not is determined, and the accuracy of hand clamping detection and the safety of use of a user can be improved.

Further, the controller 5 controls the operation of the air conditioner 1, and may further include: and if the second detection signal is the phenomenon that the third set number of times appears at the air outlet panel 2 and the second hand clamping time lasts every time, enabling the wind sweeping blade of the wind sweeping mechanism to stay at the current position.

Therefore, when the hand clamping phenomenon is detected again after the air sweeping mechanism of the air conditioner is reversed, the air sweeping blade of the air sweeping mechanism stops at the current position, the hand clamping phenomenon can be further processed, and the use safety of a user is improved.

In an optional example, the acquiring, by the microwave sensor 3, a first detection signal of whether a human body approaches the air outlet panel 2 of the air conditioner 1 to be controlled may further include: under the condition that the wind sweeping blade of the wind sweeping mechanism stays at the current position, if the microwave receiving tube does not continuously receive the reflected signal, the first detection signal indicates that no one is close to the air outlet panel 2.

From this, whether unmanned air outlet panel that is close to the air conditioner through continuing to detect under the condition that makes the blade of sweeping the wind stop at the current position, and then can confirm whether can take place the tong phenomenon, can promote the security that the air conditioner used and the accurate nature that the tong detected.

Further, the controller 5 controls the operation of the air conditioner 1, and may further include: and if the first detection signal indicates that no person is close to the air outlet panel 2, the air sweeping blade resumes the air sweeping operation.

For example: when the lower sensor detects that a person approaches and the sensor detection function is not shielded, if the photoelectric switch continuously detects n seconds of high level or n seconds of low level for m times, the hand clamping is considered to occur (n is k-x, the value of time x can be adjusted in combination with the actual movement structure), and then if no person is detected again, the sweeping is continued. In the case of the hand clamping, the air sweeping mechanism continues to sweep air after reversing the angle b, and when the hand clamping continuously occurs for c times, the air sweeping blade stops at the current position (the current position ensures that the air outlet has a certain angle instead of any angle).

From this, through if detect that nobody is close to the air-out panel of air conditioner again and make the blade of sweeping the wind resume the operation after making the blade of sweeping the wind stop at current position, promoted the security and the reliability of air conditioner operation, also promoted the convenience that the user used.

In an optional example, the acquiring, by the microwave sensor 3, a first detection signal of whether a human body approaches the air outlet panel 2 of the air conditioner 1 to be controlled may further include: if the microwave receiving tube receives the reflected signal all the time within a set time period, the first detection signal is that the air outlet panel 2 is blocked by a fixed object or the microwave sensor 3 fails.

Therefore, whether the reflected signal is received all the time or not is determined, if the reflected signal is received continuously, the fact that the air outlet panel of the air conditioner is shielded by a fixed object or the microwave sensor fails is determined, and the detection reliability is high.

Further, the controller 5 controls the operation of the air conditioner 1, and may further include: and if the first detection signal indicates that the air outlet panel 2 is shielded by a fixed object or the microwave sensor 3 fails, shielding the detection function of the microwave sensor 3 until the air conditioner 1 is powered off and powered on again and then starting the detection function of the microwave sensor 3.

For example: when a person is detected within a certain period of time (for example, the person is detected within 10 min), the sensor is considered to be shielded by the fixed object, or the sensor per se is failed, the function is shielded, the device can be re-detected after power failure and power on, and the hand clamping function is re-started.

Therefore, the detection function of the microwave sensor is shielded when the air outlet panel of the air conditioner is detected to be shielded by a fixed object or the microwave sensor fails, energy consumption required by detection is saved, and the air conditioner is good in humanization.

Through a large amount of experimental verifications, adopt the technical scheme of this embodiment, combine microwave sensor to come common judgement through photoelectric switch, solve cabinet air-conditioner air-out grid tong and have the problem of painful sense, promote to prevent that tong function experiences, alleviate tong painful sense.

According to the embodiment of the invention, the air conditioner corresponding to the hand-clamping prevention control device is also provided. The air conditioner may include: the anti-pinch control device is characterized in that the anti-pinch control device comprises a control device body.

In an optional implementation mode, the scheme of the invention combines a photoelectric switch with a microwave sensor for joint judgment, solves the problem that the air outlet grille of the cabinet air conditioner is painful to clamp hands, and simultaneously ensures that the air conditioner can achieve the aim of normally protecting and stopping when the motor is locked due to the fact that a real structural part of the air conditioner is clamped; thereby promote and prevent tong function experience, alleviate tong pain and feel. For example: experience hands-on means that a specialized person experiences this function before product development is completed and the market is released.

In an optional example, a doppler microwave sensor is used for detecting whether a human body approaches the equipment, and the specific operation mode of the moving part and the control method of the controller are judged according to whether the human body approaches the equipment.

Among them, the microwave sensor is also called microwave radar, which is an instrument manufactured by using the doppler principle of electromagnetic waves.

Optionally, a microwave sensor is used to detect whether a human body is approaching by applying doppler effect. When no person is detected to approach, the hand clamping time is k seconds; when the human body is detected to be close to the air conditioner, the hand clamping time (k seconds-x seconds) is reduced, so that the pain caused by the hand clamping is relieved, and the safety performance of the air conditioner is improved.

For example: when nobody is close to, the tong time is K seconds in order to detect that the structure has been used for a long time or can have the card pause under the good condition of not installing, and time K seconds here is longer time, and here is still done the detection in order to prevent that the structure can report the trouble and not leave the complete machine if the air supply mechanism can't open of blocking completely.

In an alternative example, the microwave sensor is installed below the air outlet panel, and can be placed inside or on the surface of the air conditioner panel, as shown in fig. 2. Fig. 3 is a schematic diagram of a detection area of a sensor, a specific detection range (for example, an angle, a distance, etc.) can be adjusted according to actual needs, and the microwave sensor is connected with an air conditioner controller through a wire to perform signal transmission.

For example: the specific angle range can be 0-360 degrees, the emission angle of the microwave sensor can be changed by adjusting the angle of the structure, and a plurality of sensors are required to be installed around the air conditioner if the effect of 360 degrees is achieved. According to the actual needs, objects in certain ranges need to be detected for adjustment according to the development requirements of products, for example, 0-135 degrees shown in fig. 3, or objects within 0-180 degrees need to be detected by other products, the angle and distance can be changed by adjusting the power of the sensor and adjusting the structure for mounting the sensor.

For example: when the angle range is adjusted, referring to the angle in fig. 3, the sensor can be installed at any angle on 135 degrees, the structure is a plastic part structure, and the structural part can be made into any radian, that is, the installation position of the sensor can be adjusted by adjusting the radian of the structural part.

Optionally, in the scheme of the present invention, the detection mode is as follows:

1. the microwave sensor can adopt a combined mode of an infrared transmitting tube and an infrared receiving tube. The infrared transmitting tube transmits infrared light, if someone is in front of the sensor, the infrared light is subjected to diffuse reflection, and the receiving tube receives infrared signals. If the receiving tube receives the signal, the front of the air conditioner is judged to be occupied, and if the receiving tube does not receive the signal, the front of the air conditioner is judged to be unoccupied.

2. The infrared transmitting tube transmits infrared light with specific waveform, error correction measures are added in the program to process the signal, the receiving tube receives the same waveform, the signal is judged to be correct, otherwise, the signal is judged to be interference signal, and no processing is carried out. For example: according to the characteristics of the transmission and the reception of the sensor, the successful reception is considered after receiving the continuous low level within a certain time limit, and the error correction measures are to correct the error on the received low level, the time is continuous, and the continuous low level time is in a required range.

Wherein, in order to prevent the false action, only after detecting the above-mentioned signal for N times continuously, regard as really valid, otherwise judge as the invalid signal; if an unsatisfactory signal occurs within N times, the clear 0 starts counting N times again.

Optionally, in the scheme of the present invention, the detection steps are as follows:

step 1, when a lower sensor (such as a microwave sensor) detects that no person approaches, wind sweeping is executed according to normal function logic, after hands are clamped for m times and k seconds each time, an FC fault needs to be reported to stop the whole machine from running, so that when a real structural part is clamped, the wind sweeping cannot be opened, the whole machine is started to run again, and potential safety hazards are caused.

For example: mode 1 in fig. 4 may refer to the aforementioned absence of human access, and the wind sweeping mechanism still detects according to normal logic, such as the photoelectric switch detects high level or low level for 3 seconds.

For example: mode 2 in fig. 4 can mean that preventing that the structure from really blocking, means that the structure blocks the phenomenon, and the structure blocks and divides into multiple reason, because the structure itself moves unsmoothly or structure fracture, warp etc. reason and leads to, if the structure blocks that the sweep wind structure of air conditioner then can't normally open, the operation of starting up again leads to the air conditioner unable normal utilization evaporimeter to trade cold and heat, the potential safety hazard appears this moment. The detection mode can not really prevent the structural part from being blocked, but can prevent the potential safety hazard caused by the fact that the air supply mechanism cannot be normally opened when the structural part is blocked.

For example: the situation of the wind sweeping stop and the normal operation of the whole machine in fig. 4 may be as follows: the normal sweeping mechanism has the clamping hand under the condition that a person is detected in the sweeping process, and after the sweeping mechanism is continuously swept for m times, the sweeping mechanism does not rotate any more but stops at the current position, because the clamping hand only occurs under the sweeping condition of the sweeping mechanism.

And 2, when the lower sensor detects that a person approaches and the sensor detection function is not shielded, if the photoelectric switch continuously detects n seconds of high level or n seconds of low level for m times, the hand clamping is considered to occur (n is k-x, the value of time x can be adjusted by combining with the actual motion structure), and then if no person is detected, the sweeping is continued.

In the case of the hand clamping, the air sweeping mechanism continues to sweep air after reversing the angle b, and when the hand clamping continuously occurs for c times, the air sweeping blade stops at the current position (the current position ensures that the air outlet has a certain angle instead of any angle).

For example: the value of x needs to be judged according to the structure, for example, in combination with the structural design of the air conditioner, the time for detecting the high level (or the low level) by the photoelectric switch is 600ms, and in the absence of the detection of the sensor, the program is designed to detect the high level or the low level lasting for 3s to ensure the reliability, but the pain feeling is obvious after the hand clamping time is long. When a person is detected to approach after the sensor (e.g., microwave sensor) is added, the time for gripping the hands can be appropriately adjusted to shorten, for example, when the time for gripping the hands is adjusted to 1s, then x is 3 seconds-1 second is 2 seconds, that is, when a person is detected to approach, the time for gripping the hands is changed from the original 3 seconds to 1 second, which prevents the person from having a noticeable pain feeling when the person grips the hands before the air conditioner, but the 1 second is more than the above-mentioned 600ms, which is necessary to ensure that the photoelectric switch does not falsely detect and ensure the reliability. The specific time is determined according to the high and low level time detected by the photoelectric switch, for example: if the high level or low level time detected by the photoelectric switch is 600ms, n is a time which is larger than 600ms and smaller than k seconds, so that the hand clamping is not painful, and the real hand clamping is ensured when the hand clamping occurs, but the misjudgment caused by the influence of other external factors is avoided.

And 3, when a person is detected within a certain period of time (for example, the person is detected within 10 min), the sensor is considered to be shielded by a fixed object, or the sensor per se is failed, the function is shielded, the device can be detected again after power failure and power up, and the hand clamping function is executed according to the step 1.
