Description

Technical Field

[0001] The present invention relates to the technical field of dehumidification equipment, and specifically, to a method for controlling a germicidal lamp in a dehumidification equipment, a dehumidification equipment applying the method for controlling a germicidal lamp in a dehumidification equipment, and a computer-readable storage medium applying the method for controlling a germicidal lamp in a dehumidification equipment. Background Art

[0002] At present, in order to increase functional applications, dehumidification devices such as dehumidifiers and air conditioners usually integrate dehumidification modules and sterilization lamp modules in the dehumidification devices, so that the dehumidification devices can not only dehumidify but also sterilize the air, thereby improving the user experience.

[0003] However, the germicidal lamp is generally turned on and off manually by the user. Since the sterilization effect cannot be perceived by the user, there may be problems such as the sterilization time is too short and the sterilization effect is insufficient, or the sterilization time is too long and the life of the germicidal lamp module is wasted.

[0004] In order to overcome the above problems, in an existing air conditioner, after the user turns on the sterilization function of the air conditioner, the room area is obtained through a distance sensor, and the turning-on time of the sterilization lamp is determined according to the indoor space volume and the current wind speed value. The sterilization lamp is turned on and the duration of the continuous turning-on time is controlled, and then the sterilization lamp is automatically turned off. This can prevent the sterilization lamp from being turned on for too short a time and failing to achieve the sterilization effect, and can also prevent the sterilization lamp from being turned on for too long and reducing its service life.

[0005] However, installing distance sensors on air conditioners or dehumidifiers is costly and difficult to implement.

[0006] Therefore, it is necessary to consider a more optimized control method of germicidal lamps. Summary of the invention

[0007] The first object of the present invention is to provide a method for controlling a germicidal lamp in a dehumidification device that can automatically control the on-time of a germicidal lamp to avoid the germicidal lamp being on for insufficient or excessive time, thereby achieving the purpose of effective sterilization, while also being able to save energy and extend the life of the ultraviolet germicidal lamp.

[0008] The second object of the present invention is to provide a dehumidification device that can automatically control the on-time of the germicidal lamp to avoid the germicidal lamp being on for insufficient or excessive time, thereby achieving the purpose of effective sterilization, while being able to save energy and extend the life of the ultraviolet germicidal lamp.

[0009] The third object of the present invention is to provide a computer-readable storage medium that can automatically control the on-time of a germicidal lamp to avoid the germicidal lamp being on for insufficient or excessive time, thereby achieving effective sterilization purposes, while being able to save energy and extend the life of an ultraviolet germicidal lamp.

[0010] In order to achieve the above-mentioned first purpose, the sterilization lamp control method in the dehumidification equipment provided by the present invention includes: when the dehumidification module is turned on for dehumidification, a dehumidification operation is performed on the closed physical space where the dehumidification equipment is located, and the dehumidification time required to dehumidify the closed physical space to a first preset humidity under the current dehumidification mode is obtained; according to the dehumidification time, the sterilization time required for the sterilization lamp to complete complete sterilization in the closed physical space is determined; when the sterilization lamp is turned on for sterilization, the sterilization lamp is controlled to work for the sterilization time and then turned off.

[0011] It can be seen from the above scheme that the control method of the germicidal lamp in the dehumidification equipment of the present invention obtains the dehumidification time required for dehumidification of the closed physical space during dehumidification, and determines the sterilization time required for the germicidal lamp to complete complete sterilization in the closed physical space according to the dehumidification time. Since the dehumidification efficiency of the dehumidifier is relatively stable under the premise that the volume of the room is fixed, and the time required for complete sterilization of the dehumidifier in rooms of the same volume is also fixed, the dehumidification time required for dehumidification of the closed physical space can be converted into the sterilization time required to complete complete sterilization, and then the single working time of the germicidal lamp can be reasonably controlled to avoid the germicidal lamp being turned on for insufficient or too long, so as to achieve the purpose of effective sterilization, and at the same time save energy and extend the life of the ultraviolet germicidal lamp. At the same time, there is no need to set up an additional physical space size detection device, which reduces costs.

[0012] In a further scheme, the sterilization time T is obtained by the following formula: T=k*k1*t / ΔT, where k is the dehumidification and sterilization effect coefficient, k=N / H, H is the dehumidification amount of the dehumidification module per unit volume, and N is the complete sterilization efficiency of the sterilization lamp per unit volume; k1 is the coefficient of the current dehumidification mode; ΔT is the first humidity difference between the ambient humidity T1 before dehumidification and the first preset humidity T2, and t is the dehumidification time.

[0013] It can be seen that by setting a reasonable conversion formula between dehumidification time and sterilization time, the accuracy of the sterilization time of the germicidal lamp can be improved.

[0014] In a further solution, the coefficient of the current dehumidification mode is set according to the current ambient temperature and the windshield during dehumidification.

[0015] It can be seen that the coefficient of the current dehumidification mode is set according to the current ambient temperature and the windshield during dehumidification. The coefficient of the current dehumidification mode can be adjusted according to the ambient temperature and the windshield to improve the accuracy of the sterilization time.

[0016] In a further scheme, after the step of controlling the germicidal lamp to turn off after working for a sterilization period, it also includes: turning on the dehumidification module to dehumidify, obtaining a second humidity difference between the current humidity after the dehumidification module has worked for a first preset period of time and the initial humidity of the closed physical space when the dehumidification module is turned on, and controlling the working state of the germicidal lamp according to the second humidity difference.

[0017] It can be seen that since the user opens the window or the room door for a long time, or the room is not well sealed, possible bacteria or viruses from the outdoors may invade the room. Therefore, the second humidity difference between the current humidity after the dehumidification module has been working for the first preset time and the initial humidity of the closed physical space when the dehumidification module is turned on is obtained, and the working state of the sterilization lamp is controlled according to the second humidity difference, thereby improving the sterilization effect.

[0018] In a further scheme, the step of controlling the working state of the germicidal lamp according to the second humidity difference includes: when the second humidity difference is greater than the upper limit of the preset difference range, starting the germicidal lamp to perform sterilization work; when the second humidity difference is within the preset difference range and the current humidity is greater than the second preset humidity, starting the germicidal lamp to perform sterilization work; when the second humidity difference is within the preset difference range and the current humidity is less than or equal to the second preset humidity, keeping the germicidal lamp in an off state; when the second humidity difference is less than the lower limit of the preset difference range, keeping the germicidal lamp in an off state.

[0019] It can be seen that the airtightness of the room can be determined by the second humidity difference, and the working state of the germicidal lamp can be controlled according to the airtightness, thereby improving the sterilization effect and saving energy consumption.

[0020] In a further solution, when the second humidity difference is greater than the upper limit of the preset difference range, or when the second humidity difference is within the preset difference range and the current humidity is greater than the second preset humidity, a reminder message to close the physical space is issued.

[0021] It can be seen that when the second humidity difference is greater than the upper limit of the preset difference range, or when the second humidity difference is within the preset difference range and the current humidity is less than or equal to the second preset humidity, it means that the sealing of the room is poor, and the user needs to be reminded to perform the sealing operation of the physical space so that the user can be informed and perform corresponding operations.

[0022] In a further solution, the step of starting the germicidal lamp to perform the sterilization work includes: after the germicidal lamp works for a second preset time, entering the next second humidity difference acquisition.

[0023] It can be seen that after the germicidal lamp is started to perform the sterilization work for the second preset time, the next second humidity difference is obtained to make the next room sealing degree judgment.

[0024] In a further solution, after the step of determining the sterilization time required for the germicidal lamp to complete complete sterilization in the closed physical space according to the dehumidification time, the step further includes: storing the sterilization time.

[0025] It can be seen that after obtaining the sterilization time required for the germicidal lamp to complete complete sterilization in the closed physical space, in order to facilitate the control of the germicidal lamp next time, the sterilization time can be stored so that it can be called when the germicidal lamp is working, avoiding repeated dehumidification to obtain the sterilization time.

[0026] In order to achieve the second purpose of the present invention, the present invention provides a dehumidification device including a processor and a memory, the memory stores a computer program, and when the computer program is executed by the processor, the steps of the sterilization lamp control method in the dehumidification device are implemented.

[0027] In order to achieve the third purpose of the present invention, the present invention provides a computer-readable storage medium on which a computer program is stored. When the computer program is executed by a controller, the steps of the above-mentioned method for controlling a germicidal lamp in a dehumidification device are implemented.

[0031] The present invention is further described below in conjunction with the accompanying drawings and embodiments. DETAILED DESCRIPTION

[0032] The method for controlling a germicidal lamp in a dehumidification device of the present invention is a computer program applied to the dehumidification device, and is used to control the germicidal lamp in the dehumidification device.

[0033] In this embodiment, see Figure 1 The dehumidification device is provided with a main control module 1, a dehumidification module 2 and a germicidal lamp 3, and the dehumidification module 2 and the germicidal lamp 3 are electrically connected to the main control module 1. The dehumidification module 2 is used to dehumidify the indoor air, and the germicidal lamp 3 is used to sterilize the indoor air. The dehumidification module 2 and the germicidal lamp 3 adopt devices well known to those skilled in the art, which will not be described in detail here. The dehumidification device includes an air conditioner or a dehumidifier. The dehumidification module 2 adopts a dehumidification module of a condensation dehumidification method, and the condensation dehumidification method is a technology well known to those skilled in the art, which will not be described in detail here. The germicidal lamp 3 is an ultraviolet germicidal lamp.

[0034] Embodiment of the control method of the germicidal lamp in the dehumidification equipment:

[0035] like Figure 2As shown, in this embodiment, the control method of the germicidal lamp in the dehumidification device is first executed in step S1 when the dehumidification module is turned on for dehumidification, and the closed physical space where the dehumidification device is located is dehumidified to obtain the dehumidification time required to dehumidify the closed physical space to the first preset humidity in the current dehumidification mode. The first preset humidity is pre-set according to experimental data.

[0036] In general, since the area of ​​the room used by the user is fixed, under the same mode and the same ambient temperature, the dehumidification capacity of the dehumidifier is relatively fixed, the rate at which the humidity in the room decreases is relatively fixed, and the time required for complete sterilization by the germicidal lamp in a room of the same area is also fixed. Therefore, based on this principle, the dehumidification time required for dehumidification of a closed physical space can be converted into the sterilization time required to complete complete sterilization.

[0037] After the dehumidification time is obtained, step S2 is performed to determine the sterilization time required for the germicidal lamp to complete complete sterilization in the closed physical space according to the dehumidification time. After the dehumidification time is obtained, the size of the closed physical space can be estimated, and then the sterilization time required to complete complete sterilization can be estimated according to the size of the physical space.

[0038] In this embodiment, the sterilization time T is obtained by the following formula: T = k*k1*t / ΔT, where k is the dehumidification and sterilization effect coefficient, k = N / H, H is the dehumidification amount of the dehumidification module in a unit volume, and N is the complete sterilization efficiency of the germicidal lamp in a unit volume; k1 is the coefficient of the current dehumidification mode; ΔT is the first humidity difference between the ambient humidity T1 before dehumidification and the first preset humidity T2, and t is the dehumidification time. By setting a reasonable conversion formula for the dehumidification time and the sterilization time, the accuracy of the sterilization time of the germicidal lamp can be improved.

[0039] In this embodiment, the coefficient of the current dehumidification mode is set according to the current ambient temperature and the windshield during dehumidification. After the user turns on the dehumidification module, the ambient temperature of the room is detected, and the coefficient of the corresponding dehumidification mode is selected according to the windshield selected by the user, such as a high windshield, a medium windshield, a low windshield or a silent windshield, according to the current ambient temperature and the windshield during dehumidification. The coefficient of the dehumidification mode can be pre-set according to experimental data. By selecting the coefficient of the current dehumidification mode according to the ambient temperature and the windshield, the accuracy of the sterilization time can be improved.

[0040] In this embodiment, after the step of determining the sterilization time required for the germicidal lamp to complete complete sterilization in the closed physical space according to the dehumidification time, the method further includes: storing the sterilization time. After obtaining the sterilization time required for the germicidal lamp to complete complete sterilization in the closed physical space, the sterilization time can be stored to facilitate the control of the germicidal lamp next time so that it can be called when the germicidal lamp is working, thereby avoiding repeated dehumidification to obtain the sterilization time.

[0041] After obtaining the sterilization time, step S3 is executed to determine whether to turn on the germicidal lamp for sterilization. When sterilization is required, the control module of the dehumidifier can be used for control, for example, the control panel or remote control of the dehumidifier can be used to control the germicidal lamp to be turned on for sterilization.

[0042] If the germicidal lamp is not turned on for sterilization, continue to execute step S3 for continuous detection. When the germicidal lamp is turned on for sterilization, execute step S4 to control the working sterilization time of the germicidal lamp and then turn it off. When the instruction to turn on the germicidal lamp for sterilization is obtained, by reading the sterilization time stored in the storage device, the working time of the germicidal lamp can be controlled by the sterilization time when the germicidal lamp is controlled, so as to reasonably control the single working time of the germicidal lamp, avoid the germicidal lamp being turned on for insufficient or too long, achieve the purpose of effective sterilization, and save energy and extend the life of the germicidal lamp.

[0043] After turning off the germicidal lamp, execute step S5, turn on the dehumidification module for dehumidification, obtain the second humidity difference between the current humidity after the dehumidification module has been working for the first preset time and the initial humidity of the closed physical space when the dehumidification module is turned on, and control the working state of the germicidal lamp according to the second humidity difference. Among them, the preset time can be pre-set according to experimental data. Since the user opens the window or the room door for a long time, or the room is not well sealed, possible bacteria or viruses outside may invade the room. Therefore, the second humidity difference between the current humidity after the dehumidification module has been working for the first preset time and the initial humidity of the closed physical space when the dehumidification module is turned on is obtained, and the working state of the germicidal lamp is controlled according to the second humidity difference, thereby improving the sterilization effect.

[0044] In this embodiment, when the working state of the germicidal lamp is controlled according to the second humidity difference, step S51 is first performed to determine whether the second humidity difference is greater than the upper limit of the preset difference range. The preset difference range can be preset according to experimental data.

[0045] When the second humidity difference is greater than the upper limit of the preset difference range, step S52 is executed to start the germicidal lamp for sterilization. If the second humidity difference is greater than the upper limit of the preset difference range, it means that the sealing of the closed physical space is poor. In order to better sterilize the closed physical space, it is necessary to start the germicidal lamp for sterilization, thereby reducing bacteria in the external air.

[0046] When the second humidity difference does not satisfy the upper limit of the preset difference range, step S53 is executed to determine whether the second humidity difference is within the preset difference range. The preset difference range can be preset according to experimental data.

[0047] When the second humidity difference is within the preset difference range, step S54 is executed to determine whether the current humidity is less than or equal to the second preset humidity. If the second humidity difference is within the preset difference range, it means that the humidity has not changed. In order to further confirm whether the humidity has not changed due to the long-term convection state between the closed physical space and the outdoor environment, or due to the closed physical space being in a dry state, it is necessary to confirm whether the second humidity difference is within the preset difference range.

[0048] If the current humidity is greater than the second preset humidity, step S52 is executed to start the germicidal lamp for sterilization. If the current humidity is greater than the second preset humidity, it means that the reason why the humidity has not changed is that the closed physical space and the outdoor environment are in a long-term convection state. Therefore, the germicidal lamp needs to be started for sterilization.

[0049] If the current humidity is less than or equal to the second preset humidity, step S55 is executed to keep the germicidal lamp in the off state. If the current humidity is less than or equal to the second preset humidity, it means that the reason why the humidity has not changed is that the closed physical space is already in a dry state and has good sealing. Therefore, sterilization is not required and the germicidal lamp remains in the off state.

[0050] When the second humidity difference is less than the lower limit of the preset difference range during step S53, step S55 is executed to keep the germicidal lamp in the off state. If the second humidity difference is less than the lower limit of the preset difference range, it means that the airtightness of the enclosed physical space is good and sterilization is not required. Therefore, the germicidal lamp can be kept in the off state to reduce energy consumption.

[0051] In addition, in this embodiment, when the second humidity difference is greater than the upper limit of the preset difference range, or when the second humidity difference is within the preset difference range and the current humidity is greater than the second preset humidity, a reminder message to seal the physical space is issued. If the sealing of the room is poor, it is necessary to remind the user to perform the sealing operation of the physical space so that the user can be informed and perform corresponding operations.

[0052] In this embodiment, after the step of starting the germicidal lamp to perform the sterilization work, the method further includes: after the germicidal lamp has been working for a second preset time, the second humidity difference value is obtained for the next time. After the germicidal lamp has been started for a second preset time, the second humidity difference value is obtained for the next time, so as to make the next room sealing degree judgment.

[0053] From the above, it can be known that the control method of the germicidal lamp in the dehumidification equipment of the present invention obtains the dehumidification time required for dehumidification of the closed physical space during dehumidification, and determines the sterilization time required for the germicidal lamp to complete complete sterilization in the closed physical space according to the dehumidification time. The dehumidification time required for dehumidification of the closed physical space can be converted into the sterilization time required to complete complete sterilization, and then the single working time of the germicidal lamp can be reasonably controlled to avoid the germicidal lamp being turned on for insufficient or too long, so as to achieve the purpose of effective sterilization, and at the same time save energy and extend the life of the ultraviolet germicidal lamp. At the same time, there is no need to set up an additional physical space size detection device, which reduces costs.
