TECHNICAL FIELD
[0001] The present application relates to the technical field of household appliances, in particular to a control method and device of a humidifier and a computer readable storage medium. BACKGROUND
[0002] The water level detection accuracy of the existing humidifier is low, which causes the problem of residual water in the water tank of the humidifier to be unable to be effectively solved. The cost of the high-precision water level detection device is too high to be implemented in the humidifier product. Due to the defects of the water level detection, the residual water in the water tank causes the water tank to be mildewed and smelly, which is a common problem of the current humidifier and the biggest pain point for users.
[0003] The traditional humidifier generally uses a water level float sensor to detect the water level of the water tank, which has the following significant defects in actual use: 1) The water level float sensor has low accuracy, and the float is easily affected by impurities, bubbles and water level fluctuations in the water tank, which causes misjudgment of the water level detection. The misjudgment of the water level detection will cause the humidifier to dry out or fail to start; 2) The water level float sensor has high cost. The structure of the water level float sensor is complex, and requires relatively precise mechanical parts, which causes the manufacturing cost of the water level float sensor to be high; 3) The water level float sensor has poor reliability. The water level float sensor is prone to jamming, falling off or corrosion, which shortens the service life of the equipment and cannot solve the problem of bacterial growth caused by residual water in the water tank. SUMMARY
[0004] Therefore, the present application provides a control method of a humidifier to solve the technical problem that the drying program of the humidifier in the prior art cannot balance the detection cost and detection accuracy.
[0005] In a first aspect, the present application provides a control method of a humidifier, the humidifier being provided with a wet curtain, a water tank and a pressure tablet sensor arranged in the water tank. The control method of the humidifier comprises: obtaining an initial weight of the water tank before the humidifier works and a real-time weight of the water tank during the working process of the humidifier; controlling the humidifier to perform a humidifying operation according to the real-time weight being greater than a first preset threshold value of the initial weight; and controlling the humidifier to perform a drying operation on the water tank according to the real-time weight being less than a second preset threshold value of the initial weight, wherein the first preset threshold value is greater than the second preset threshold value.
[0006] Beneficial effects: The embodiment proposes to upgrade the detection logic of the water tank weight of the humidifier without increasing the hardware cost, and to detect the initial weight and the drying weight of the water tank of the humidifier by using the weight sensor detection, so that the weight detection of the humidifier can consider both the accuracy and the cost, thereby meeting the dual requirements of the user for the water level detection accuracy and the water level detection cost of the humidifier.
[0007] In an optional implementation, the control of the humidifier to perform the drying operation on the water tank further includes: determining that the humidifier completes the drying operation on the water tank according to that the real-time weight is less than the second preset threshold of the initial weight, and the real-time weight remains unchanged within a preset time.
[0008] Beneficial effects: When the real-time weight of the water tank remains unchanged within a preset time, it means that the accumulated water in the water tank is basically evaporated by heating, at which time the humidifier can be controlled to stop the drying operation on the water tank, thereby reducing the dry burning phenomenon of the humidifier during the drying operation on the water tank.
[0009] Further, through the double verification of that the real-time weight is less than the second preset threshold of the initial weight, and the real-time weight remains unchanged within a preset time, the misjudgment phenomenon of the humidifier to the drying condition of the accumulated water in the water tank can be reduced, and the accuracy of the drying operation of the humidifier on the water tank can be improved.
[0010] In an optional implementation, the control of the humidifier to perform the drying operation on the water tank further includes: controlling the humidifier to stop the drying operation on the water tank according to that the real-time weight is greater than the first preset threshold of the initial weight, and the humidifier returns to the humidification operation.
[0011] Beneficial effects: During the drying operation of the humidifier on the water tank, the humidifier will perform real-time weight detection on the water tank. If the user needs to use the humidifier for humidification operation again and adds water to the water tank, the weight of the water tank will increase to be greater than the first preset threshold of the initial weight. At this time, the humidifier needs to stop the drying operation and return to the humidification operation state, thereby improving the flexibility of the humidification to switch between the humidification operation and the drying operation, and improving the working intelligence of the humidifier.
[0012] Further, the first preset threshold is greater than the second preset threshold, which can reduce the misjudgment of the humidifier in the humidification operation and the drying operation, and prevent the humidifier from frequently switching between the drying operation and the humidification operation.
[0013] In an optional implementation, the humidifier is provided with an APP / knob, and the obtaining of the initial weight of the water tank before the humidifier works further includes: setting the first preset threshold through the APP / knob according to the area and / or volume of the water tank.
[0014] Beneficial effects: In order to enable different humidifiers to start the humidification operation at the same depth, the application proposes to adjust the first preset threshold of the water tank according to the area and / or volume of the water tank, so that the water tank of different areas and / or volumes can finally start the humidification operation at the same depth, that is, the humidification logic proposed in the application embodiment can achieve the effect of float detecting water level, thereby improving the accuracy of the humidifier in detecting the water level of the water tank.
[0015] In an optional embodiment, the humidifier is provided with an APP / knob, and the obtaining of the initial weight of the water tank before the humidifier works further includes: setting the second preset threshold through the APP / knob according to the area and / or volume of the water tank.
[0016] Beneficial effects: In order to enable the humidifier to dry the accumulated water in the water tank at the target depth, the application proposes to adjust the second preset threshold of the water tank according to the area and / or volume of the water tank, so that the water tank of different areas and / or volumes can finally be dried at the same target depth, that is, the drying logic proposed in the application embodiment can achieve the effect of float detecting water level, thereby improving the accuracy of the humidifier in detecting the water level of the water tank.
[0017] In an optional embodiment, the determining of the completion of the drying operation of the humidifier on the water tank further includes: obtaining a drying weight value of the water tank after drying, recording the drying weight value and the initial weight; accumulating a plurality of sets of drying weight values and initial weights after the humidifier completes a plurality of working cycles; and determining the scale condition of the water tank according to the plurality of sets of drying weight values and initial weights.
[0018] Beneficial effects: The control method of the humidifier proposed in the application embodiment not only can realize the timing control of the humidification operation and the timing control of the drying operation, but also can realize the judgment of the scale condition in the water tank, so that the user can timely remove the scale according to the scale condition in the water tank, thereby reducing the influence of the scale in the water tank on the humidification operation and the drying operation of the humidifier.
[0019] In an optional embodiment, the obtaining of the initial weight of the water tank before the humidifier works specifically includes: obtaining a drying weight value of the humidifier after completing the last drying operation, and setting the drying weight value as the initial weight.
[0020] Beneficial effects: Taking the drying weight value of this time as the initial weight of the next work of the water tank can reduce the influence of water adding and water draining on the real-time weight of the water tank in the next work of the water tank, thereby improving the accurate control of the humidifier on the real-time weight, the accumulated water amount, the humidification timing and the drying timing of the water tank.
[0021] In an alternative embodiment, the obtaining the initial weight of the water tank before the humidifier is in operation specifically comprises: obtaining a detected weight value of the water tank during a start-up process of the humidifier, and setting the detected weight value as the initial weight.
[0022] Beneficial effects: taking the detected weight value of the water tank during the start-up process as the initial weight of the water tank can reduce the influence of water adding and draining on the real-time weight of the water tank during the operation process, so as to improve the accurate control of the humidifier on the real-time weight, water accumulation amount, humidifying opportunity and drying opportunity of the water tank.
[0023] In a second aspect, the application provides a control device of a humidifier, which is used to implement the control method of the humidifier of the first aspect of the application. The control device of the humidifier comprises: an obtaining module, configured to obtain an initial weight of a water tank before the humidifier is in operation, and a real-time weight of the water tank during the operation process of the humidifier; and a control module, configured to control the humidifier to perform a humidifying operation according to that the real-time weight is greater than a first preset threshold value of the initial weight; and the control module is further configured to control the humidifier to perform a drying operation on the water tank according to that the real-time weight is less than a second preset threshold value of the initial weight, wherein the first preset threshold value is greater than the second preset threshold value.

[0030] In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are some but not all of the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the protection scope of the present application.

In addition, the terms "first", "second", "third" are only for the purpose of description, and cannot be understood as indicating or implying relative importance.
[0032] In the description of the present application, it should be noted that unless otherwise explicitly specified and limited, the terms "mounting", "connection", "communication" should be understood broadly, for example, it can be fixed communication, or detachable communication, or integral communication; it can be mechanical communication, or electrical communication; it can be direct connection, or indirect connection through an intermediate medium; it can be internal communication of two elements, or wireless communication, or wired communication. For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.
[0033] The water tank in the humidifier is detected by a water level float sensor or a weight sensor. The water level float sensor has the problems of high cost and easy mis-detection, and the weight sensor can reduce the cost, but also has the problem of easy mis-detection: the weight of the water tank changes during use, for example, the wear of the water tank causes the weight of the water tank to decrease, or the scale in the water tank causes the weight of the water tank to increase, at this time, the fixed initial value of the water tank will have mis-detection phenomenon.
[0034] In order to solve the technical problem that the water level detection technology of the humidifier in the related art cannot balance the precision and the cost, the application proposes, without increasing the hardware cost, upgrading the detection logic of the weight of the water tank of the humidifier, and dynamically detecting the initial weight and the drying weight of the water tank of the humidifier by using the weight sensor, so that the weight detection of the humidifier can balance the precision and the cost, thereby meeting the dual requirements of the user on the water level detection precision and the water level detection cost of the humidifier.
[0035] The embodiments of the application will be described below in conjunction with Figures 1 to 3 .
[0036] As shown in Figure 1 , according to the embodiments of the application, in one aspect, the application provides a control method of a humidifier, the humidifier is provided with a wet curtain, a water tank and a tablet sensor arranged on the water tank, the control method of the humidifier comprises: acquiring the initial weight of the water tank before the humidifier works and the real-time weight of the water tank during the working process of the humidifier; controlling the humidifier to perform a humidifying operation according to that the real-time weight is greater than a first preset threshold value of the initial weight; and controlling the humidifier to perform a drying operation on the water tank according to that the real-time weight is less than a second preset threshold value of the initial weight, wherein the first preset threshold value is greater than the second preset threshold value.
[0037] In the embodiments, the application proposes, without increasing the hardware cost, upgrading the detection logic of the weight of the water tank of the humidifier, and dynamically detecting the initial weight and the drying weight of the water tank of the humidifier by using the weight sensor, so that the weight detection of the humidifier can balance the precision and the cost, thereby meeting the dual requirements of the user on the water level detection precision and the water level detection cost of the humidifier.
[0038] The application aims to solve the industry and user pain points of the evaporative humidifier in the current industry, i.e. the water tank is prone to mildew and odor. In addition, it can also solve the problem of false detection caused by the fixed weight threshold set by the weight sensor, and solve the problem of poor user experience.
[0039] It should be noted that the specific values of the first preset threshold value and the second preset threshold value are not set in the embodiments, because the first preset threshold value and the second preset threshold value need to be flexibly set according to the area and the volume of the water tank, so that the water tanks with different areas and volumes can perform the humidifying operation and the drying operation at the same target depth.
[0040] As shown in Figure 1 and Figure 2 , in some embodiments, the control of the humidifier to perform the drying operation on the water tank further comprises: determining that the humidifier completes the drying operation on the water tank according to that the real-time weight is less than the second preset threshold value of the initial weight, and the real-time weight remains unchanged within a preset time. In the above embodiments, when the real-time weight of the water tank remains unchanged within the preset time, it indicates that the accumulated water in the water tank is basically evaporated by heating, at this time, the humidifier can be controlled to stop the drying operation on the water tank, so as to reduce the dry burning phenomenon of the humidifier during the drying operation on the water tank.
[0041] Further, through the double verification of the real-time weight being less than the second preset threshold of the initial weight and the real-time weight remaining unchanged within the preset time, the misjudgment phenomenon of the humidifier in the drying of the accumulated water in the water tank can be reduced, and the accuracy of the drying operation of the humidifier on the water tank is improved.
[0042] As shown in Figure 1 and Figure 2 In some embodiments, after the humidifier performs the drying operation on the water tank, the humidifier further controls the humidifier to stop the drying operation on the water tank according to the real-time weight being greater than the first preset threshold of the initial weight, and the humidifier returns to the humidifying operation.
[0043] In this embodiment, during the drying of the water tank by the humidifier, the humidifier performs real-time weight detection on the water tank. If the user needs to use the humidifier for humidifying operation again and performs water adding operation on the water tank, the weight of the water tank will increase to be greater than the first preset threshold of the initial weight. At this time, the humidifier needs to stop the drying operation and return to the humidifying operation state, so as to improve the flexibility of the humidifier in switching between the humidifying operation and the drying operation, and improve the intelligent work of the humidifier.
[0044] Further, the present application sets the first preset threshold to determine the humidifying operation and the second preset threshold to determine the drying operation, and the first preset threshold is greater than the second preset threshold, which can reduce the misjudgment of the humidifier in the humidifying operation and the drying operation, and prevent the humidifier from frequently switching between the drying operation and the humidifying operation.
[0045] Specifically, the tablet type sensor is used to detect the weight instead of the traditional water level float detection. When the weight gain of the water tank is less than the second preset threshold such as 0.25 kg, the humidifier enters the drying program of the water tank, and the real-time weight detection is set. When the weight gain of the water tank exceeds the first preset threshold such as 0.5 kg, the normal working state is restored. If the weight gain of the water tank is always below the second preset threshold such as 0.25 kg, the drying of the water tank is continued until the weight gain of the water tank is detected to be a fixed value and remains unchanged for 10 seconds. At this time, the humidifier can enter the shutdown state, so as to ensure that the water tank is completely dried and no water remains.
[0046] As shown in Figure 1 and Figure 2As shown, in some embodiments, the humidifier is equipped with an APP / knob, and before obtaining the initial weight of the water tank before the humidifier is put into operation, it further includes: setting a first preset threshold according to the area and / or volume of the water tank via the APP / knob.
[0047] In the above embodiments, in order to enable different humidifiers to start humidification at the same depth, this application proposes that the first preset threshold of the water tank needs to be adjusted according to the area and / or volume of the water tank, so as to ensure that water tanks with different areas and / or volumes can eventually start humidification at the same depth. In other words, the humidification logic proposed in this application can achieve the effect of float detection of water level, thereby improving the accuracy of the humidifier's detection of the water level in the water tank.
[0048] In some embodiments, the humidifier is equipped with an APP / knob, and before obtaining the initial weight of the water tank before the humidifier is put into operation, it further includes setting a second preset threshold according to the area and / or volume of the water tank via the APP / knob. In the above embodiment, in order for the humidifier to dry the water in the tank to the target depth, this application proposes that a second preset threshold of the water tank needs to be adjusted according to the area and / or volume of the water tank, so as to ensure that water tanks with different areas and / or volumes can be dried to the same target depth. In other words, the drying logic proposed in this application embodiment can achieve the effect of float detection of water level, thereby improving the accuracy of the humidifier's detection of water level in the tank.
[0049] like Figure 1 and Figure 2 As shown, in some embodiments, after determining that the humidifier has completed the drying operation on the water tank, the method further includes: obtaining the dried weight value of the water tank after drying, recording the dried weight value and the initial weight; accumulating multiple sets of dried weight values and the initial weight after the humidifier has completed multiple working cycles; and determining the scale condition of the water tank based on the multiple sets of dried weight values and the initial weight.
[0050] In this embodiment, the humidifier control method proposed in this application can not only control the timing of humidification and drying operations, but also determine the scale level in the water tank, so that users can remove scale in a timely manner according to the scale level in the water tank, thereby reducing the impact of scale in the water tank on the humidifier's humidification and drying operations.
[0051] Specifically, the weight of the water tank will change during use. For example, wear and tear on the water tank will reduce its weight, or scale buildup in the tank will increase its weight. In such cases, the fixed threshold may be misdetected. Therefore, before each start-up of the humidifier, the initial weight of the water tank should be detected first, and then the water in the tank should be evaluated according to the threshold.
[0052] like Figure 1 andFigure 2 In some embodiments, the obtaining of the initial weight of the water tank before the humidifier is in operation specifically includes: obtaining a drying weight value of the humidifier after a last drying operation is completed, and setting the drying weight value as the initial weight; or obtaining a detected weight value of the water tank during a start-up process of the humidifier, and setting the detected weight value as the initial weight.
[0053] In the present embodiment, the drying weight value of the present time is taken as the initial weight of the water tank for the next operation, which can reduce the influence of water adding and draining on the real-time weight of the water tank during the next operation, so as to improve the accurate control of the humidifier on the real-time weight, the accumulated water amount, the humidifying timing and the drying timing of the water tank.
[0054] In an alternative implementation, the obtaining of the initial weight of the water tank before the humidifier is in operation specifically includes: obtaining a detected weight value of the water tank during a start-up process of the humidifier, and setting the detected weight value as the initial weight.
[0055] In the present embodiment, the detected weight value of the water tank during the start-up process is taken as the initial weight of the water tank, which can reduce the influence of water adding and draining on the real-time weight of the water tank during the operation, so as to improve the accurate control of the humidifier on the real-time weight, the accumulated water amount, the humidifying timing and the drying timing of the water tank. Specific embodiments: The present application specifically relates to a water tank water level detection and working state control system of an evaporative humidifier, and in particular to an intelligent control scheme for realizing high-precision and low-cost water level monitoring through a tablet-type weight sensor and automatically switching drying / working / shut-down states.
[0057] The tablet-type weight sensor is arranged at the bottom of the water tank, and the cost is more than 30% lower than that of a traditional water level sensor. The weight sensor directly detects the weight increase of the water tank. The second preset threshold value is set to 0.25 kg (wherein 0.25 kg is an example value that can be adjusted), and is taken as a state switching reference. The second preset threshold value can be optimized, and the 0.25 kg threshold value is set based on the residual water amount of the water tank to ensure the balance between sensitivity and practicability. The user can adjust the threshold value (such as 0.2-0.3 kg) through an APP or a knob to adapt to different water tank capacities.
[0058] The working logic control is as follows: when the real-time weight of the water tank is lower than the initial weight of the water tank+0.25 kg, the humidifier enters a drying program of the water tank, and the real-time weight is detected. When the real-time weight of the water tank exceeds the initial weight of the water tank+0.5 kg again, the normal humidifying working state of the humidifier is restored. If the real-time weight of the water tank is lower than the initial weight of the water tank+0.25 kg and remains unchanged for 30 s, it is considered that the water tank has been completely dried, and the weight at this time is recorded as the initial weight value for the next time. The humidifier enters a shut-down state, so as to ensure that the water tank is completely dried and no water remains.
[0059] The specific control logic is described in Table 1 below. Table 1
[0060] The control method of the humidifier of the embodiment has the following advantages: Higher accuracy: weight detection is not affected by water quality and impurities, and the data is stable and reliable (error <±0.05 kg); Lower cost: The tablet type sensor is a planar structure, and does not require mechanical floating components, reducing manufacturing costs by 40%; Improved safety: completely solves the problem of residual water in the water tank, and eliminates the risk of bacterial growth and dry burning.
[0061] The present application replaces the traditional water level float with a tablet type weight sensor, with the core advantages of high precision, low cost and high reliability, solving the industry pain points of existing humidifier water level detection. The intelligent control logic (the real-time weight gain of the water tank is greater than 0.25 kg, at which time the humidifier performs humidification work; the real-time weight gain of the water tank is less than 0.25 kg, at which time the humidifier performs drying operation; the real-time weight gain of the water tank is equal to a certain value and does not change for 30s, at which time the humidifier is turned off) ensures that the water tank is completely dry, significantly improving product safety and user experience.
[0062] As Figure 1 Figure 2 Figure 3 shown, in a second aspect, the present application provides a humidifier control device 30 for implementing the control method of the humidifier of the first aspect of the present application. The humidifier control device 30 comprises: an acquisition module 301 for acquiring the initial weight of the water tank before the humidifier works, and the real-time weight of the water tank during the working process of the humidifier; a control module 302 for controlling the humidifier to perform humidification operation according to the real-time weight being greater than a first preset threshold value of the initial weight; the control module 302 is further used for: controlling the humidifier to perform drying operation on the water tank according to the real-time weight being less than a second preset threshold value of the initial weight, wherein the first preset threshold value is greater than the second preset threshold value.
[0063] In the present embodiment, the humidifier control device 30 provided by the present embodiment has all the technical effects of the above-mentioned control method of the humidifier by adopting the control method of the humidifier of the above-mentioned embodiment, and the specific technical effects of the humidifier control device 30 will not be described here.
