Description

TECHNICAL FIELD

[0001] The present application relates to the air conditioning technical field, and particularly relates to an air conditioner sterilization control method based on pulse sterilization and an air conditioner. BACKGROUND

[0002] With the development of the times, the air conditioner has become one of the essential household appliances in daily life. During use, bacteria carried by external air enter the air conditioner, and condensation is generated due to the cold and hot temperature difference inside the air conditioner, and part of the devices are sometimes in a humid environment, which is easy to breed bacteria, and the bacteria spread with the air conditioner blowing may affect human health; therefore, the air conditioner with sterilization function emerges as the times require.

[0003] The current mature sterilization technology used in air conditioners, such as UVC ultraviolet sterilization, requires a long time for sterilization, and plastic parts are easily aged when exposed to UVC ultraviolet light for a long time; UVC ultraviolet light leakage can easily cause harm to the human body, and may also produce ozone and other defects.

[0004] With the continuous development of sterilization technology, people have developed a new sterilization technology-pulse sterilization technology, which usually uses a xenon lamp tube to release energy in the form of full-spectrum white light through the self-ionization and avalanche discharge of inert gas in a very short time, and the instantaneous light power can reach 10 million times of ordinary sunlight power, which can instantly kill various microorganisms, and at the same time, it will not bring obvious temperature change to the sterilized object.

[0005] However, the existing pulse sterilization air conditioner often has a single sterilization logic, and it is difficult to obtain good sterilization effect in some operating states of the air conditioner. At the same time, the user cannot perceive the sterilization operation, resulting in poor user experience. SUMMARY

[0006] Therefore, the present application aims to provide an air conditioner sterilization control method based on pulse sterilization and an air conditioner to solve the problems of the prior art, such as the single sterilization logic of the pulse sterilization air conditioner and the user's inability to perceive the sterilization operation.

[0007] To achieve the above-mentioned purpose, the technical scheme of the present application is as follows:

[0008] The application discloses an air conditioner sterilization control method based on pulse sterilization, which comprises at least two pulse sterilization modes, and for any pulse sterilization mode, the air conditioner stops receiving a control signal, a power supply module of a pulse sterilization device is turned on, and a third preset time length is delayed, and after the pulse sterilization device completes charging, a pulse flash process is performed; the pulse flash time length is different for any two pulse sterilization modes; and the air conditioner plays sterilization music corresponding to the pulse sterilization mode while performing any pulse sterilization mode. Thus, the application can meet the sterilization requirements of different users and different air conditioner use conditions by setting at least two pulse sterilization modes with different sterilization time lengths; meanwhile, the air conditioner plays corresponding sterilization music while performing sterilization, so that the user can intuitively perceive the progress of the air conditioner sterilization process, and the air conditioner use experience of the user is improved. In addition, the air conditioner stops receiving the control signal while performing the pulse sterilization mode, and the pulse sterilization device is independently charged and discharged, so as to ensure the independent operation environment of the pulse sterilization device, guarantee that the sterilization process of the pulse sterilization device is not interrupted, and make the pulse sterilization device perform a normal, complete and uninterrupted sterilization process every time the pulse sterilization mode is performed, so as to guarantee the single sterilization effect and ensure the safe operation of the pulse sterilization device every time.

[0009] Further, the pulse sterilization mode comprises a fast sterilization mode and a slow sterilization mode, the pulse flash time length is 20s-40s in the process of performing the fast sterilization mode, and the air conditioner plays fast sterilization music; and the pulse flash time length is 100s-150s in the process of performing the slow sterilization mode, and the air conditioner plays slow sterilization music. Thus, the air conditioner has multiple pulse sterilization modes, can meet the sterilization requirements of different users and different air conditioner use conditions, and can also make the user intuitively perceive the progress of different pulse sterilization modes according to different music playing, so as to improve the air conditioner use experience of the user.

[0010] Further, for any pulse sterilization mode, the playing time length of the sterilization music = the third preset time length + the pulse flash time length, so that the sterilization music can accompany the entire sterilization mode execution process, the user can perceive the progress of the specific sterilization mode, and the air conditioner use experience of the user is improved.

[0011] Further, after the air conditioner executes the pulse sterilization mode, the air conditioner fragrance module is turned on, the indoor fan is started, the air guide door is opened, and after running for a fifth preset time length, the fragrance module is turned off, and after a sixth preset time length, the air conditioner returns to the state of the air conditioner before the pulse sterilization mode is executed. Preferably, while the fragrance module is turned on, the indoor fan runs at a low wind speed, and the air guide door is opened to a horizontal state. Thus, after sterilization, by turning on the fragrance module, the indoor fan, the air guide door and other components, the peculiar smell that may be generated after sterilization is inhibited, the comfort demand of the user for indoor air is ensured, and at the same time after sterilization, it is also helpful to restore the operation of the related components that have been turned off, and finally return to the state of the air conditioner before the pulse sterilization mode is executed, to ensure the normal use of the air conditioner by the user.

[0012] Further, for any one pulse sterilization mode, the air conditioner sterilization control method comprises: S1, confirming that the pulse sterilization mode is entered; S2, acquiring the current state of the air conditioner; S3, judging whether the air conditioner is in the shutdown state; if yes, directly executing the pulse sterilization mode; if no, proceeding to step S4; S4, judging whether the air conditioner is in the air supply mode; if yes, proceeding to step S6; if no, proceeding to step S5; S5, turning off the outdoor unit, and adjusting the current mode of the air conditioner to the air supply mode, and after running for a first preset time length, proceeding to step S6;

[0013] S6, adjusting the indoor unit to the lowest wind speed, closing the air guide door, and after running for a second preset time length, turning off all loads of the air conditioner, and executing the pulse sterilization mode. Thus, before the pulse sterilization is performed, first, the current state of the air conditioner is distinguished, a specific air conditioner control process is performed in a specific air conditioner state, and then the pulse sterilization mode is entered. On the one hand, before the pulse sterilization mode is executed, all loads of the air conditioner are turned off, so that the air conditioner components do not interfere with the start and operation of the pulse sterilization device. On the other hand, for other non-air supply modes, by adjusting to the air supply mode first, the condensate water in the indoor unit is discharged and evaporated as much as possible, the humidity in the indoor unit is reduced, the influence of the residual condensate water in the air conditioner on the sterilization effect is avoided, or the heat exchanger of the indoor unit is fully cooled, the internal temperature of the indoor unit is restored to room temperature as much as possible, and the damage of the pulse sterilization device due to the high temperature of the working environment is avoided. In addition, whether in the air supply mode alone or in the state of jumping to the air supply mode from other modes, the wind speed is reduced and the air guide door is closed, so that the airflow carrying bacteria enters (and stays) in the indoor unit as much as possible, and then all loads of the air conditioner are turned off to execute the pulse sterilization mode, so that the air conditioner can effectively improve the sterilization effect of a single sterilization regardless of the running mode.

[0014] Further, after the execution of any one of the pulse sterilization modes is completed, a sterilization closing mode is performed, the sterilization closing mode comprising: closing the enabling port of the pulse sterilization device, stopping the output of pulses, and then closing the power supply module of the pulse sterilization device. After the execution of the pulse sterilization mode is completed, the sterilization closing mode is performed according to a specific operation sequence, to ensure that the pulse sterilization device is normally and safely closed.

[0015] Further, after the execution of the sterilization closing mode is completed, the air conditioner shields any one of the pulse sterilization modes within a seventh preset time length. Thus, the pulse sterilization device can have a certain time length of heat dissipation and cooling time after the execution of one pulse sterilization mode, to avoid continuous multiple operations of the pulse sterilization device due to user mis-touch or other abnormal conditions, and to prevent hidden dangers caused by long-time heating of the pulse lamp.

[0016] Further, during the execution of any one of the pulse sterilization modes, the air conditioner displays a sterilization time, and the total time length of the sterilization time is a third preset time length + the time length of the pulse flash lamp. Thus, during the sterilization process, the air conditioner displays the sterilization time, so that the user can intuitively know the progress of the sterilization process of the air conditioner, and the use experience of the air conditioner of the user is improved.

[0017] An air conditioner adopts the air conditioner sterilization control method, the air conditioner comprises an outdoor unit and an indoor unit, the outdoor unit is connected with the indoor unit, the indoor unit is internally provided with a pulse sterilization device, and the pulse sterilization device can emit a pulse flash lamp and is used for pulse sterilization of the indoor unit.

[0018] Compared with the prior art, the air conditioner sterilization control method and the air conditioner based on pulse sterilization have the following advantages:

[0019] The air conditioner sterilization control method and the air conditioner based on pulse sterilization can meet the sterilization requirements of different users and different air conditioner use conditions by setting at least two pulse sterilization modes with different sterilization time lengths. Meanwhile, the air conditioner plays corresponding sterilization music during the execution of sterilization, so that the user can intuitively perceive the progress of the sterilization process of the air conditioner, and the use experience of the air conditioner of the user is improved. In addition, during the execution of the pulse sterilization mode, the air conditioner stops receiving a control signal, and the pulse sterilization device is independently charged and discharged, to ensure the independent operation environment of the pulse sterilization device, to protect the sterilization process of the pulse sterilization device from being interrupted, to ensure that the pulse sterilization device can execute a normal, complete and undisturbed sterilization process during each pulse sterilization mode, and to ensure the single sterilization effect and the safe operation of the pulse sterilization device.

[0020] Before the pulse sterilization is performed, the current state of the air conditioner is distinguished, specific air conditioner control processes are performed in specific air conditioner states, and then the pulse sterilization mode is entered. On the one hand, all loads of the air conditioner are turned off before the pulse sterilization mode is executed, so that the components of the air conditioner do not interfere with the start and operation of the pulse sterilization device. On the other hand, for other non-sending modes, the air conditioner is first adjusted to the sending mode, so that the condensate water in the indoor unit is discharged and evaporated as much as possible, the humidity in the indoor unit is reduced, the residual condensate water in the air conditioner is avoided to affect the sterilization effect, or the heat exchanger of the indoor unit is fully cooled, and the internal temperature of the indoor unit is restored to room temperature as much as possible, so as to avoid damage of the pulse sterilization device due to high working environment temperature.

[0021] In addition, whether in the single sending mode or in the state of jumping to the sending mode from other modes, the air flow carrying bacteria is made to enter (and stay) into the indoor unit as much as possible by reducing the air speed and closing the air guide door, and then all loads of the air conditioner are turned off to execute the pulse sterilization mode, so that the sterilization effect of a single sterilization can be effectively improved regardless of the current running mode of the air conditioner. BRIEF DESCRIPTION OF DRAWINGS

[0022] The accompanying drawings, which form a part of the present application, are intended to provide further understanding of the present application and are incorporated herein for a purpose of explanations. In the drawings:

[0023] Figure 1 A flowchart of a sterilization control method of an air conditioner based on pulse sterilization according to an embodiment of the present application. DETAILED DESCRIPTION

[0024] The inventive concepts of the present disclosure will be described using terminology commonly employed by those skilled in the art and having reference to the drawings. However, these inventive concepts can be embodied in many different forms and should not be construed as limited to the embodiments set forth herein.

[0025] It should be noted that the embodiments in the present application and the features in the embodiments can be combined with each other without conflict.

[0026] The present application will be described in detail below with reference to the accompanying drawings and in conjunction with the embodiments.

[0027] In order to solve the problems of single sterilization logic of pulse sterilization air conditioner and user's inability to perceive the sterilization operation in the prior art, the embodiment provides an air conditioner sterilization control method based on pulse sterilization, which includes at least two pulse sterilization modes. For any pulse sterilization mode, the method includes: the air conditioner stops receiving a control signal, a power supply module of a pulse sterilization device is turned on, and a third preset time length is delayed, and after the pulse sterilization device completes charging, a pulse flash process is performed. The pulse flash time lengths of any two pulse sterilization modes are different. While any pulse sterilization mode is performed, the air conditioner plays sterilization music corresponding to the pulse sterilization mode.

[0028] Thus, by setting at least two pulse sterilization modes with different sterilization time lengths, the sterilization requirements of different users and different air conditioner use conditions can be met. At the same time, the air conditioner plays corresponding sterilization music while performing sterilization, so that the user can intuitively perceive the progress of the air conditioner sterilization process, which is beneficial to improve the user's air conditioner use experience. In addition, when the pulse sterilization mode is performed, the air conditioner stops receiving the control signal, and the pulse sterilization device is independently charged and discharged, which ensures the independent operation environment of the pulse sterilization device and protects the sterilization process of the pulse sterilization device from being interrupted, so that the pulse sterilization device can perform a normal, complete and uninterrupted sterilization process every time the pulse sterilization mode is performed, which is beneficial to ensure the single sterilization effect and also ensures the safe operation of the pulse sterilization device every time.

[0029] Specifically, as shown in the accompanying drawings, Figure 1 For any pulse sterilization mode, the method includes:

[0030] S1, confirming entering the pulse sterilization mode;

[0031] The user can confirm entering the pulse sterilization mode through a remote controller, or the air conditioner can perform the pulse sterilization mode according to a preset schedule. It should be noted that step S1 is not entering and performing the pulse sterilization mode, but confirming the time when the pulse sterilization mode will be entered next.

[0032] S2, obtaining the current state of the air conditioner;

[0033] The current state of the air conditioner can be any conventional mode or conventional state of the air conditioner, such as the shutdown state (which can also be understood as the standby state of the air conditioner not running) of the air conditioner, the refrigeration mode, the heating mode, the air supply mode, the dehumidification mode, the defrosting mode and the like in the prior art.

[0034] S3, judging whether the air conditioner is in the shutdown state; if yes, directly performing the pulse sterilization mode; if no, performing step S4;

[0035] S4, judging whether the air conditioner is in the air supply mode; if yes, proceeding to step S6; if no, proceeding to step S5;

[0036] S5, closing the outdoor unit and adjusting the current mode to the air supply mode, and proceeding to step S6 after running for a first preset time length;

[0037] S6, adjusting the indoor unit to the lowest wind speed, closing the air guide door, and executing the pulse sterilization mode after running for a second preset time length.

[0038] The closing of the outdoor unit refers to the closing of the compressor, the outdoor fan and other components of the outdoor unit; the closing of all loads of the air conditioner refers to the closing of the indoor unit, the outdoor unit, and the closing of the electric heating, the air sweeping motor, the outdoor compressor, the outdoor fan, the indoor fan, the outdoor unit power supply, the indoor unit display panel power supply and other components of the air conditioner. The first preset time length and the second preset time length are preset values of the air conditioner, which can be preset by the air conditioner manufacturer before the air conditioner is shipped, for example, the first preset time length is 50-100s, and the second preset time length is 15-30s.

[0039] In steps S3-S6, if the air conditioner is in the shutdown state, all components are not running, and will not interfere with the start and operation of the pulse sterilization device, so the pulse sterilization mode can be entered immediately.

[0040] If the air conditioner is in the air supply mode, the air flow carrying bacteria can enter (and stay) into the indoor unit as much as possible by reducing the wind speed and closing the air guide door, and then all loads of the air conditioner are closed to execute the pulse sterilization mode, which is beneficial to improve the sterilization effect of a single sterilization.

[0041] If the air conditioner is in the cooling mode, the heating mode, the dehumidification mode, the defrosting mode and other conventional modes, the indoor unit may be in an environment with a large amount of condensate water (such as cooling) or a high temperature (such as heating). First, the current mode is adjusted to the air supply mode by closing the outdoor unit, and then the process of switching from the air supply mode to the pulse sterilization mode (i.e. step S6) is executed after running for a period of time. Thus, by adjusting to the air supply mode first, the condensate water in the indoor unit is discharged and evaporated as much as possible, the humidity in the indoor unit is reduced, the residual condensate water in the air conditioner is avoided to affect the sterilization effect, or the heat exchanger of the indoor unit is fully cooled, and the internal temperature of the indoor unit is recovered to room temperature as much as possible, so as to avoid damage of the pulse sterilization device due to the high temperature of the working environment.

[0042] Therefore, before the pulse sterilization is performed, the current state of the air conditioner is distinguished first, a specific air conditioner control process is performed in a specific air conditioner state, and then the pulse sterilization mode is entered. On the one hand, all loads of the air conditioner are turned off before the pulse sterilization mode is executed, so that the components of the air conditioner do not interfere with the start and operation of the pulse sterilization device. On the other hand, for other non-sending modes, the air conditioner is first adjusted to the sending mode, so that the condensate water in the indoor unit is discharged and evaporated as much as possible, the humidity in the indoor unit is reduced, the residual condensate water in the air conditioner is avoided to affect the sterilization effect, or the heat exchanger of the indoor unit is fully cooled, and the internal temperature of the indoor unit is restored to room temperature as much as possible, so as to avoid damage of the pulse sterilization device due to the high temperature of the working environment.

[0043] In addition, whether in the single sending mode or in the state of jumping to the sending mode from other modes, the air flow carrying bacteria is made to enter (and stay) into the indoor unit as much as possible by reducing the air speed and closing the air guide door, and then all loads of the air conditioner are turned off to execute the pulse sterilization mode, so that the sterilization effect of a single sterilization can be effectively improved regardless of the current running mode of the air conditioner.

[0044] The pulse flash lamp process is that the enable port of the pulse sterilization device is opened, a preset number of high-level pulses are output every interval through the control port, and then the enable port is closed. For example, the pulse sterilization device outputs 30 high-level pulses every 1s, and the excitation time of each high-level pulse is 5ms. The third preset time length is also an air conditioner preset parameter, for example, the third preset time length is 8s-15s.

[0045] The method performs the sterilization closing mode after any one of the pulse sterilization modes is executed. The sterilization closing mode includes that the enable port of the pulse sterilization device is closed, the pulse output is stopped, the power supply module of the pulse sterilization device is turned off, a delay of a fourth preset time length is performed, the air conditioner aroma module is turned on, the indoor fan is started, the air guide door is opened, the aroma module is turned off after running for a fifth preset time length, a delay of a sixth preset time length is performed, and the air conditioner returns to the air conditioner state obtained in step S2 and enters the sterilization cooling mode. The fourth preset time length, the fifth preset time length, and the sixth preset time length are all air conditioner preset parameters, for example, the fourth preset time length is 4s-6s, the fifth preset time length is 40s-80s, and the sixth preset time length is 4s-6s. After the aroma module is turned on, the indoor fan is preferably operated at a low air speed, and the air guide door is opened to be horizontal.

[0046] Therefore, after the pulse sterilization mode is executed, the sterilization closing mode is performed according to a specific operation sequence, on the one hand, to ensure that the pulse sterilization device is normally and safely closed, and on the other hand, to inhibit the odor that may be generated after sterilization by turning on the aroma module, indoor fan, air guide door and other components, to protect the user's comfort demand for indoor air, and at the same time, after sterilization, it is also helpful to restore the operation of the related components that have been closed, and finally to restore to the air conditioner state obtained in step S2, to protect the normal use of the air conditioner by the user.

[0047] The sterilization cooling mode is that the air conditioner shields any one pulse sterilization mode within a seventh preset time length, that is, the air conditioner does not receive an instruction to enter the pulse sterilization mode, nor does it perform the pulse sterilization mode. Therefore, after the pulse sterilization device is executed once, it can have a certain time length of cooling time, to avoid continuous multiple operations of the pulse sterilization device due to user misoperation or other abnormal conditions, and to prevent hidden dangers caused by long-time heating of the pulse lamp.

[0048] At the same time of executing step S5, the air conditioner displays a first sterilization countdown through the display module, and at the same time of executing step S6, the air conditioner displays a second sterilization countdown through the display module. The first sterilization countdown includes at least a first preset time length, which can be understood as a mode conversion time, so that the user can intuitively realize the process of switching the air conditioner from the current mode to the air supply mode. Of course, since step S5 is necessarily executed before step S6, the time length of the first sterilization countdown can also include the time length of the second sterilization countdown, so that when the first sterilization countdown is switched to step S6, the remaining time length of the first sterilization countdown is exactly equal to the time length of the second sterilization countdown, that is, the total time length of the first sterilization countdown can be the first preset time length + the total time length of the second sterilization countdown. The second sterilization countdown includes a second preset time length, and of course, considering that it also takes a certain time (such as 15s-30s) to close all loads of the air conditioner in step S6, the total time length of the second sterilization countdown is the second preset time length + the time length of closing all loads of the air conditioner. During the display of the sterilization countdown, the nixie tube of the air conditioner display module flashes and displays the countdown. Therefore, the air conditioner performs sterilization countdown before executing the pulse sterilization mode, and displays it through the air conditioner display module, so that the user can intuitively realize that the air conditioner is preparing to sterilize, which is helpful to improve the user's air conditioner use experience.

[0049] Similarly, when entering the pulse sterilization mode, the air conditioner displays a sterilization time through the display module, and the total time length of the sterilization time is a third preset time length + the time length of the pulse flash lamp. Therefore, during the sterilization process, the air conditioner displays the sterilization time, so that the user can intuitively realize the progress of the air conditioner sterilization process, which is helpful to improve the user's air conditioner use experience. At the same time, the music module of the air conditioner plays sterilization music synchronously when the pulse sterilization mode is executed.

[0050] In the present application, the pulse sterilization mode includes fast sterilization mode and slow sterilization mode, and the user can select the pulse sterilization mode through the remote controller or the air conditioner can execute a certain pulse sterilization mode according to the pre-design plan. Preferably, in the process of executing the fast sterilization mode, the length of the pulse flash is 20-40s, and the air conditioner synchronously plays fast sterilization music with a relatively cheerful rhythm; in the process of executing the slow sterilization mode, the length of the pulse flash is 100-150s, and the air conditioner synchronously plays slow sterilization music with a relatively gentle rhythm. For any pulse sterilization mode, the playing length of the sterilization music = the third preset length + the length of the pulse flash, so that the sterilization music can accompany the entire execution process of the sterilization mode, and the user can perceive the progress of the specific sterilization mode, which is beneficial to improve the air conditioner use experience of the user.

[0051] In the present application, for any air conditioner, the pulse sterilization based air conditioner sterilization control method in the present embodiment can be used. At the same time, the air conditioner includes an outdoor unit and an indoor unit, the outdoor unit is connected with the indoor unit, the indoor unit is internally provided with a pulse sterilization device, the pulse sterilization device can emit a pulse flash for pulse sterilization of the indoor unit. The pulse sterilization device includes a pulse light module and a pulse electric control module, the pulse electric control module is connected with the pulse light module, used for controlling the pulse light module to emit a pulse flash, and the pulse light module is a high-pressure xenon pulse lamp.

[0052] In addition, the air conditioner further includes a display module, a music module, an aromatherapy module, an indoor fan, a guide vane and other conventional components of the air conditioner indoor unit; similarly, the air conditioner further includes a compressor, an outdoor fan and other conventional components of the air conditioner outdoor unit; since these conventional components can be used in the prior art, they will not be described here.

[0053] The above only describes the preferred embodiments of the present application and should not be used to limit the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application should be included in the protection scope of the present application.
