detailed description

The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, but not to limit the present invention. In addition, it should be noted that, for the convenience of description, only some structures related to the present invention are shown in the drawings but not all structures.

Embodiment one

Fig. 1 is a schematic flow chart of an air conditioner control method provided by Embodiment 1 of the present invention. This embodiment is applicable to situations such as intelligent control of the air conditioner when the user leaves the room. The method can be executed by the air conditioner control device, specifically including Follow the steps below:

Step 110, when the preset opening condition of the going-out energy-saving mode is met, start the going-out energy-saving mode corresponding to the preset opening condition.

Wherein, the going-out energy-saving mode is an energy-saving mode for enabling the air conditioner to operate with low energy consumption when the user goes out for a short time or a long time. Preferably, different energy-saving modes for going out can be set according to the length of time the user goes out.

The preset enabling condition of the going-out energy-saving mode may be: detection of a manual activation signal corresponding to the activation of the going-out energy-saving mode, and/or detection of the user leaving the room for longer than a set timeout period. Exemplarily, if the remote control of the air conditioner is provided with the "going out" function, the going out energy-saving mode can be activated by the user clicking the "going out" button of the remote control. If the "go out" function is set on the remote control of the air conditioner, and the indoor unit of the air conditioner is equipped with a human body detection device, the user can click the "go out" button on the remote control for the energy-saving mode of going out, and the human body detection device detects that the user leaves the room consecutively. The mode is enabled when the time exceeds the set departure time.

If there is no such function on the remote control of the air conditioner, the preset enabling condition of the going out energy-saving mode may also be: it is detected that the user leaves the room for longer than the set leaving time. Exemplarily, if it is detected by the human body detection device that the continuous time of the user leaving the room exceeds the set time of leaving, the going-out energy-saving mode is activated. If the time the user leaves is too short (for example, less than 5 minutes), it is not necessary to enable the energy-saving mode for going out.

Preferably, the human body detection device can be an infrared sensor (also known as an infrared sensor. Specifically, the infrared sensor can be a pyroelectric infrared sensor. Whether there are people in the room can be detected by the pyroelectric infrared sensor, that is, the pyroelectric infrared sensor Under the irradiation of infrared rays from the human body, the output signal will change, so that the main board of the air conditioner indoor unit determines whether there is a person in the room according to the output signal.

Exemplarily, whether there is human body infrared radiation in the room is detected by the pyroelectric infrared sensor on the air conditioner indoor unit, and an output signal corresponding to the detection result is obtained. The main board of the air-conditioning indoor unit acquires the output signal of the pyroelectric infrared sensor according to the set period, and can determine whether the user is in the room according to the output signal, and determine whether the user is currently stationary or walking. In order to increase the detection distance, a spherical Fresnel lens is usually added to the surface of the pyroelectric infrared sensor. In addition, the sensor used to detect whether a user has left the room can also be a Doppler effect sensor. Its detection method is similar to the infrared sensor, and can refer to the specific detection method of the infrared sensor.

When it is determined that the user leaves the room, the timer in the air conditioner can be triggered to count the length of time the user has left the room. If the calculated time for the user to leave the room exceeds the set time for leaving, the energy-saving mode for going out is enabled and the timer is reset. When the pyroelectric infrared sensor detects that the user returns to the room, start the timer and start counting again. If it is detected that the user stays in the room for a continuous time length exceeding the set time, then exit (turn off) the energy-saving mode for going out, and the timer When the timer expires, reset the timer.

Exemplarily, the camera may also be used to detect whether the user is in the room. It is determined to enable or exit the energy-saving mode according to the detection result of the camera detection method. The processing process is similar to the above-mentioned processing process using the infrared sensor detection, and will not be repeated here.

Fig. 2 is a schematic flow chart of an air conditioner entering and going out mode according to Embodiment 1 of the present invention. As shown in Figure 2, when the user inputs the signal to enable the energy-saving mode when going out through the remote control, the main board of the air conditioner indoor unit obtains the detection result signal of the infrared sensor, processes the signals corresponding to the remote control and the infrared sensor, and then judges whether the above-mentioned signal meets the requirements. Preset activation conditions for going out energy-saving mode. If the preset opening condition is met, start the going out energy-saving mode corresponding to the preset opening condition, and the main board of the air conditioner indoor unit sends the start signal of the going out energy-saving mode to the main board of the air conditioner outdoor unit, so that the main board of the air conditioner outdoor unit calculates according to the going out energy-saving mode and the ambient temperature target frequency, and output the target frequency to the compressor for frequency regulation. If the preset opening condition of the going-out energy-saving mode is not satisfied, the main board of the air-conditioning indoor unit will continue to process signals corresponding to the remote controller or the infrared sensor.

It should be noted that if it is detected that the user returns to the room again (for example, after the user goes out and returns to the room, the infrared sensor continuously detects that there is someone in the room within 0.1 minutes; ” function), it will send out energy-saving mode exit signal to the main board of the outdoor unit of the air conditioner, so that the outdoor unit of the air conditioner can calculate the target frequency according to the temperature set by the user, and output the target frequency to the compressor for frequency adjustment. FIG. 3 is a schematic flow chart of an air conditioner exiting the going-out mode according to Embodiment 1 of the present invention. As shown in FIG. 3 , the main board of the air conditioner indoor unit acquires and processes the signals corresponding to the remote control unit and the infrared sensor, and judges whether the preset closing conditions of the going-out energy-saving mode are satisfied according to the above signals. For example, when an infrared sensor is installed on the indoor unit of the air conditioner, if it is detected that the user returns to the room, and the user is still in the room within 0.1 consecutive minutes, the short-time going out energy-saving mode is turned off.

Another way to realize the shutdown may be that when the indoor unit of the air conditioner is not equipped with an infrared sensor, if the off-going energy-saving mode shutdown command sent by the remote controller is detected, the energy-saving mode for going out is turned off.

Step 120 , adjust the running state of the air conditioner according to the going out energy-saving mode in combination with the ambient temperature or the running time of the going out energy-saving mode.

Exemplarily, if the user goes out for a short time, the energy-saving mode for going out for a short time may be activated. At this time, the operating state of the air conditioner can be adjusted according to the temperature inside and outside the room and the current operating frequency of the air conditioner. If the user goes out for a long time, the energy-saving mode for going out for a long time can be activated. At this time, the running state of the air conditioner can be adjusted according to the running time of the energy-saving mode when going out for a long time. When the going-out energy-saving mode is the short-time going-out energy-saving mode, the control strategy for the short-time going-out energy-saving mode is executed. For example, the main board of the outdoor unit of the air conditioner obtains the current outdoor temperature, the current indoor temperature and the current operating frequency. According to the deviation between the current outdoor temperature and the current indoor temperature, and the deviation between the set target temperature and the current indoor temperature, query the pre-stored temperature-frequency relationship table to obtain the deviation value between the target operating frequency and the current operating frequency. A target operating frequency is determined according to the deviation value and the current operating frequency, and the operating frequency of the air conditioner is adjusted according to a set cycle to achieve the target operating frequency.

When the energy-saving mode of going out is the energy-saving mode of being away for a long time, execute the control policy of the energy-saving mode of being out for a long time. For example, the running time and current running frequency of the energy-saving mode of going out for a long time are acquired. The pre-stored time and frequency deviation table is queried according to the running time to obtain the deviation value between the target running frequency and the current running frequency. A target operating frequency is determined according to the deviation value and the current operating frequency, and the operating frequency of the air conditioner is adjusted according to a set cycle to achieve the target operating frequency. When the running time of the energy-saving mode of going out for a long time reaches the preset closing time, the air conditioner is controlled to be turned off. Through the above adjustments, when the user returns to the room after going out, the indoor temperature will be relatively moderate. If the air conditioner is in the cooling mode, the indoor temperature will not be too low; if the air conditioner is in the heating mode, the indoor temperature will not be too high. Therefore, a comfortable experience can be brought to the user by adjusting the operating state of the air conditioner.

In this embodiment, when the preset opening condition of the going out energy saving mode is met, the going out energy saving mode corresponding to the preset opening condition is started; according to the going out energy saving mode, combined with the ambient temperature or the running time of the going out energy saving mode is adjusted The operating status of the air conditioner to reduce the energy consumption of the air conditioner. By adopting the above-mentioned technical solution, the problem that the current air conditioner does not have an energy-saving mode for going out or the energy-saving mode for going out is not smart enough can be solved, and the operating state of the air conditioner can be adjusted intelligently, achieving the goal of reducing energy consumption of the air conditioner and providing users with a comfortable indoor temperature. .

Embodiment two

Fig. 4 is a schematic flow chart of an air conditioner control method provided in Embodiment 2 of the present invention. In this embodiment, the step "when the preset enabling condition of the going out energy saving mode is met, start the going out energy saving mode corresponding to the preset turning on condition" in the first embodiment is optimized to "if the manual opening corresponding to the going out energy saving mode is detected signal, and the user leaves the room for longer than the set short-time leave time, start the short-time going out energy saving mode; if no manual start signal corresponding to the going out energy saving If the set duration of long-time absence is set, the energy-saving mode for long-time absence will be activated." Referring to Figure 4, the embodiment of the present invention specifically includes the following steps:

Step 210, acquire attribute information of the air conditioner remote controller.

Wherein, the attribute information includes an out-of-office function field. Exemplarily, if the going out function field is 1, it means that the air conditioner remote controller has the function of "going out". If the going out function field is 0, it means that the remote controller of the air conditioner does not have the "going out" function.

Step 220 , judging whether the remote control of the air conditioner has the "go out" function, if yes, execute step 230 ; otherwise, execute step 270 .

After acquiring the attribute information, the main board of the air conditioner indoor unit extracts the outgoing function field. If the going out energy-saving function field is 1, it means that the air conditioner remote control has the function of "going out", and step 230 is executed. If the going out energy-saving function field is 0, it means that the air conditioner remote control does not have the "going out" function, and step 270 is executed.

Step 230 , judging whether a manual activation signal corresponding to activation of the energy-saving mode for going out is detected, and if yes, execute step 240 ; otherwise, execute step 250 .

Exemplarily, when the user clicks the "go out" button on the air conditioner remote control, the air conditioner remote control generates a manual start signal and sends it to the air conditioner indoor unit.

Step 240 , judging whether the time for the user to leave the room exceeds the set time for leaving the room in a short time, if so, perform step 290 ; otherwise, perform step 260 .

Wherein, the preset duration for the user to leave for a short time may preferably be 5 minutes.

Step 250 , judging whether the duration of the user's leaving the room exceeds the set long-term leaving duration, if yes, execute step 280 ; otherwise, execute step 260 .

When the manual start signal corresponding to the start of the energy-saving mode for going out is detected, the detection result of the infrared sensor is acquired. When the detection result of the infrared sensor is that the user has left the room, a timer is started to record the length of time the user has left the room. The length of time that the user leaves the room is compared with the length of time that the user leaves the room for a long time, if it exceeds the length of time that is set for a long time, then execute step 280; if it does not exceed the length of time that you leave for a long time, execute step 260 .

Exemplarily, the preset time for the user to leave for a long time can be set according to the actual situation, preferably 30 minutes

Step 260, maintaining the original running state of the air conditioner.

Exemplarily, when the user is going out, if the "go out" function of the remote control of the air conditioner is pressed, and the time the user leaves the room exceeds the set time of leaving (the infrared sensor detects that there is no one in the room for five consecutive minutes), The energy-saving mode will be turned on when you go out for a short time. Exemplarily, if the user only presses the "go out" function of the remote control of the air conditioner, but the user leaves the room for less than the set time for leaving (the infrared sensor detects that the user leaves the room for less than 5 minutes), then If you go out for a short time, the energy-saving mode will be turned off, and the air conditioner will maintain the original operating state.

Step 270 , judging whether the user has left the room for longer than the preset time, if so, execute step 280 ; otherwise, execute step 260 .

Step 280, start the energy-saving mode of going out for a long time.

Exemplarily, if the remote control of the air conditioner has the "going out" function, but the user does not enable this function when leaving the room, if it is detected that the user has left the room for longer than the set long time When no one is detected in the room), the energy-saving mode will be turned on when going out for a long time.

Exemplarily, if the remote control of the air conditioner does not have the "going out" function, if the infrared sensor detects that there is no one in the room within 5 consecutive minutes, the long-term going-out energy-saving mode will also be turned on.

After the energy-saving mode of going out for a long time is started, the operating state of the air conditioner is adjusted according to the control strategy corresponding to the energy-saving mode of going out for a long time.

Step 290, start the energy-saving mode for going out for a short time.

After the energy-saving mode of going out for a short time is started, the operating state of the air conditioner is adjusted according to the control strategy corresponding to the energy-saving mode of going out for a short time.

The second embodiment, on the basis of the above-mentioned embodiments, refines the process of "activating the energy-saving mode for going out corresponding to the preset enabling condition when the preset enabling condition of the energy-saving mode for going out is met". By setting different conditions for turning on different energy-saving modes for going out, the energy-saving mode for going out can be turned on in a targeted manner, and then the operating state of the air conditioner can be intelligently adjusted to achieve the effect of reducing the energy consumption of the air conditioner.

Further, if the remote control of the air conditioner has the "go out" function, but the air conditioner is not equipped with detection devices such as infrared sensors, if the user triggers the "go out" function of the remote control, the short-term going out energy-saving mode will be activated. When you get to the room, you can turn off the "going out" function through the remote control to restore the original operating state of the air conditioner.

Embodiment three

Fig. 5 is a schematic flow chart of an air conditioner control method provided by Embodiment 3 of the present invention. This embodiment refines the process after the step "starting the energy-saving mode for going out for a short time" in the above-mentioned embodiment. Referring to Figure 5, the embodiment of the present invention specifically includes the following steps:

Step 310, start the energy-saving mode of going out for a short time.

Step 320, obtaining the current outdoor temperature, the current indoor temperature and the current operating frequency.

Exemplarily, since the air conditioner has two modes of cooling and heating, in different modes, the operating frequency of the air conditioner needs to be adjusted accordingly according to the current indoor and outdoor temperatures. The main board of the outdoor unit of the air conditioner obtains the outdoor temperature, the indoor temperature and the current operating frequency of the compressor.

Step 330: According to the deviation between the current outdoor temperature and the current indoor temperature, and the deviation between the set target temperature and the current indoor temperature, query the pre-stored temperature-frequency relationship table to obtain the deviation value between the target operating frequency and the current operating frequency.

Exemplarily, if ΔT1 represents the deviation between the current outdoor temperature and the current indoor temperature, ΔT2 represents the deviation between the set target temperature and the current indoor temperature, T _w represents the current outdoor temperature, and T _n represents the current indoor temperature. Then in cooling mode, ΔT1=T _w -T _n , ΔT2=28-T _n . Among them, 28 degrees Celsius represents the preset indoor standard temperature. At this temperature, the user feels the most comfortable and the air conditioner is the most energy-efficient.

Exemplarily, if the air conditioner is set to the heating mode, then ΔT1=T _n −T _w , ΔT2=T _n −18. Among them, 18 degrees Celsius also represents the preset indoor standard temperature, and at this temperature, the energy-saving effect of the air conditioner is the best.

Preferably, Table 1 represents a pre-stored statistical table of the relationship between temperature and frequency, which can be obtained through multiple experiments. As shown in Table 1, when adjusting the operating frequency of the air conditioner, the corresponding adjustment frequency can be found in the table for different indoor and outdoor temperature differences and different indoor target temperature differences.

Table 1 Prestored statistical table of temperature and frequency relationship

For example, if the indoor and outdoor temperature difference is greater than 5 degrees Celsius and less than or equal to 15 degrees Celsius, and the deviation between the target temperature and the current indoor temperature is greater than 0 degrees Celsius and less than or equal to 2 degrees Celsius, the deviation between the target operating frequency of the air conditioner and the current operating frequency is -6, and the current operating frequency The frequency is reduced by 6 Hz as the target frequency, and the target frequency is output to the compressor, so that the compressor updates the operating frequency according to the target frequency every set time. If the indoor and outdoor temperature difference is greater than 15 degrees Celsius and less than or equal to 25 degrees Celsius, and the deviation between the target temperature and the current indoor temperature is greater than 2 degrees Celsius and less than or equal to 6 degrees Celsius, the current operating frequency is reduced by 16 Hz as the target frequency, and the target frequency is output to the compressor , so that the compressor will update the running frequency according to the target frequency every set time.

Step 340: Determine the target operating frequency according to the deviation value and the current operating frequency, and adjust the operating frequency of the air conditioner according to the set period to achieve the target operating frequency.

Exemplarily, when adjusting the operating frequency of the air conditioner, the operating frequency may be updated every other setting period. Wherein, the set cycle can be any time within the time period of 5 minutes to 20 minutes, preferably 15 minutes. FIG. 6 is a flow chart of calculating the execution target frequency of the mainboard of an air conditioner outdoor unit according to Embodiment 3 of the present invention. As shown in FIG. 6 , F represents the target operating frequency of the air conditioner, and F _d represents the current operating frequency of the air conditioner. ΔF is the deviation between the target operating frequency and the current operating frequency, that is, the frequency that the air conditioner needs to adjust, where F=F _d +ΔF. It can be seen from Figure 6 that when going out energy-saving mode 1 (short-time going out energy-saving mode) is activated, the main board of the outdoor unit of the air conditioner first needs to calculate the deviation (ΔT1) between the current outdoor temperature and the current indoor temperature and the difference between the set target temperature and the current indoor temperature. The temperature deviation (ΔT2), and then the deviation value (ΔF) between the target operating frequency of the air conditioner and the current operating frequency can be obtained according to Table 1, and the main board of the outdoor unit of the air conditioner can then calculate the target frequency F and output the target frequency. Then the main board of the outdoor unit of the air conditioner judges whether the set time (for example, 15 minutes) for updating the operating frequency of the air conditioner has been reached. Realize adjusting the indoor temperature in a relatively comfortable temperature range for the user. If the time to update the current operating frequency is not reached, the air conditioner will continue to output the target operating frequency. It is worth noting that if the infrared sensor detects that there are people in the room within 0.1 minutes when the air conditioner is running at the target frequency, the short-time going out mode will be turned off, that is, the air conditioner will use the temperature set by the user before going out as the target temperature and adjust its operating frequency.

On the basis of the above-mentioned embodiments, the third embodiment refines the process after "activating the energy-saving mode for going out for a short time". By combining the characteristics of the energy-saving mode of going out for a short time, setting a corresponding control strategy to intelligently adjust the operating status of the air conditioner, thereby reducing the energy consumption of the air conditioner, achieving the effect of saving energy, and at the same time bringing a comfortable user experience.

Embodiment Four

FIG. 7 is a schematic flow chart of an air conditioner control method provided in Embodiment 4 of the present invention. This embodiment refines the process after the step "starting the energy-saving mode of going out for a long time" in the above-mentioned embodiment. Referring to Figure 7, the embodiment of the present invention specifically includes the following steps:

Step 410, start the energy-saving mode of going out for a long time.

Step 420, acquiring the running time and current running frequency of the energy-saving mode of going out for a long time.

Step 430: Query the pre-stored time and frequency deviation table according to the running time to obtain the deviation value between the target running frequency and the current running frequency.

Exemplarily, the deviation ΔF between the target operating frequency F of the air conditioner and the current operating frequency Fd can be obtained according to the prestored air conditioner operating time and air conditioner operating frequency deviation statistics table. Table 2 is a statistical table of deviations between the pre-stored running time of the air conditioner and the operating frequency of the air conditioner. As shown in Table 2, as time continues to increase, the frequency of air conditioner reduction will also increase. For example, 60 minutes after the energy-saving mode of going out for a long time is started, the operating frequency of the current air conditioner needs to be reduced by 15 Hz per second. 150 minutes after the energy-saving mode of going out for a long time is activated, the operating frequency of the current air conditioner needs to be reduced by 20 Hz per second.

Table 2 Statistical table of pre-stored air conditioner running time and air conditioner operating frequency deviation

time ΔF 0min -10 30min -10 60min -15 90min -15 120min -20 150min -20

Step 440: Determine the target operating frequency according to the deviation value and the current operating frequency, and adjust the operating frequency of the air conditioner according to the set period to achieve the target operating frequency.

Exemplarily, when adjusting the operating frequency of the air conditioner, similar to the adjustment method of the energy-saving mode of going out for a short time, the operating frequency may also be updated every other set period. Among them, the setting period is preferably 30 minutes. Fig. 8 is a flow chart of calculating the execution target frequency of the mainboard of an air conditioner outdoor unit according to Embodiment 4 of the present invention. As shown in FIG. 8 , after going out energy-saving mode 2 (long-term going out energy-saving mode), the main board of the outdoor unit of the air conditioner can determine the deviation value ΔF between the target operating frequency and the current operating frequency of the air conditioner according to Table 2. Then the target operating frequency F is calculated by combining the current operating frequency of the air conditioner, and the target frequency is output. Next, the main board of the outdoor unit of the air conditioner judges whether the set time for updating the operating frequency of the air conditioner (for example, 30 minutes) has been reached. Intelligently reduce the operating frequency of the air conditioner in the absence of people to achieve energy-saving effects. If it is judged that the time for updating the current operating frequency is not reached, the main board of the outdoor unit of the air conditioner will continue to output the target operating frequency.

The energy-saving mode of going away for a long time is the same as the energy-saving mode of being away for a short time. If the infrared sensor detects that there is someone in the room within 0.1 minutes during the operation of the air conditioner at the target frequency, the long-time away mode will be turned off, that is, the air conditioner The temperature set by the user before going out will be used as the target temperature and its operating frequency will be adjusted.

Step 450 , when the running time of the energy-saving mode of going out for a long time reaches the preset off time, control the air conditioner to be turned off.

Exemplarily, in order to prevent the air conditioner from running for a long time when there is no one in the room, the air conditioner may be controlled to automatically shut down when the air conditioner has been running for a preset time. Wherein, the preset closing time may preferably be 180 minutes. When the air conditioner is running for 180 minutes in the energy-saving mode of going out for a long time, if no user turns off the "going out" function through the remote control or the infrared sensor detects that no user enters the room, the air conditioner will stop running to reduce energy consumption .

On the basis of the above-mentioned embodiments, the fourth embodiment refines the process after "starting the energy-saving mode of going out for a long time". By combining the characteristics of the energy-saving mode of going out for a long time, setting the corresponding control strategy to intelligently adjust the operating status of the air conditioner, thereby reducing the energy consumption of the air conditioner, achieving the effect of saving energy, and at the same time bringing a comfortable user experience.

As shown in FIG. 9 , the device includes: a mode initiation module 510 and a state adjustment module 520 .

Wherein, the mode starting module 510 is configured to start the going out energy saving mode corresponding to the preset starting condition when the preset starting condition of the going out energy saving mode is satisfied. The state adjustment module 520 is configured to adjust the running state of the air conditioner according to the going out energy-saving mode in combination with the ambient temperature or the running time of the going out energy-saving mode.

In this embodiment, when the preset opening condition of the going out energy saving mode is met, the going out energy saving mode corresponding to the preset opening condition is started; according to the going out energy saving mode, combined with the ambient temperature or the running time of the going out energy saving mode is adjusted The operating status of the air conditioner to reduce the energy consumption of the air conditioner.
