The humidifier also comprises a second temperature sensor used for detecting the real-time temperature of the surface of the radiator, the second temperature sensor is connected with the controller, and the controller is arranged on one side of the radiator below the water tank. Optionally, the second temperature sensor is an NTC resistor, and the NTC resistor may be attached to the controller in a direction close to the heat sink.
S30, acquiring a first temperature protection threshold value of the radiator matched with the ambient temperature value of the environment where the humidifier is located;
under different environmental temperatures, the initial temperature of the radiator is different, the water in the water tank is consumed from a high water level state to a low water level state, the temperature value of the surface of the radiator is different under different environmental temperatures when the temperature value is in the low water level state, and generally, the higher the environmental temperature is, the higher the temperature value of the surface of the radiator is when the water in the water tank reaches the low water level state; the lower the ambient temperature is, the lower the temperature of the surface of the radiator is when the water in the water tank reaches a low water level state, that is, when the water in the water tank reaches the low water level state, the temperature value of the surface of the radiator is in a proportional relation with the ambient temperature, so that the first temperature protection threshold of the surface temperature of the radiator can be determined according to the ambient temperature value of the environment where the humidifier is located, and the water shortage protection is further performed on the humidifier.
And S40, when the first temperature value on the surface of the radiator is greater than or equal to the first temperature protection threshold value, controlling the humidifier to perform water shortage protection.
Specifically, when the first temperature value on the surface of the radiator is greater than or equal to the first temperature protection threshold, it indicates that the water in the water tank cannot cool the radiator, the water in the water tank reaches a low water level state, and if the humidifier is continuously used, a potential safety hazard is caused, so that the humidifier is controlled to perform water shortage protection.
The humidifier has multiple modes of water shortage protection, the controller controls the atomizing part of the humidifier to stop working, controls the humidifier to be powered off, controls the humidifier to perform water shortage reminding and the like, and the method is not specifically limited in the application.
According to the humidifier water shortage protection method provided by the embodiment of the invention, the radiator is embedded into the bottom surface of the water tank and is in contact with water in the water tank, through water cooling, when the water tank is gradually consumed to a low water level from a full water state, the temperature of the radiator can be gradually increased, the water level change in the water tank can be judged through the temperature change of the radiator, and the corresponding target temperature protection threshold value is matched according to the environment temperature of the humidifier, so that the humidifier water shortage is effectively prevented, and the water shortage protection mechanism is simpler and more convenient and has better stability.
In this embodiment, the obtaining a first temperature protection threshold of the heat sink matched with an ambient temperature value of an environment where the humidifier is located includes:
and searching a first temperature protection threshold value of the radiator matched with the ambient temperature value of the environment where the humidifier is located according to a preset first corresponding relation table, wherein the first corresponding relation table comprises the corresponding relation between the ambient temperature value of the environment where the humidifier is located and the first temperature protection threshold value of the radiator.
The first correspondence table in this embodiment is prepared and configured in the controller at the time of factory shipment of the controller. The first corresponding relation table is used for recording the corresponding relation between the ambient temperature value of the environment where the humidifier is located and the first temperature protection threshold value of the radiator.
The controller may be configured to call the first correspondence table according to an environmental temperature value of an environment where the humidifier is located, and obtain a first temperature protection threshold of the radiator corresponding to the environmental temperature value of the environment where the humidifier is located.
Generally, the first temperature protection threshold gradually increases as the value of the ambient temperature increases. Optionally, when the ambient temperature value of the environment where the humidifier is located is 25 ℃, the first temperature protection threshold of the corresponding radiator may be set to 65 ℃, so that the water in the corresponding water tank is in a low water level state; when the ambient temperature value of the environment where the humidifier is located is 40 ℃, the first temperature protection threshold of the corresponding heat sink may be set to 80 ℃.
According to the humidifier water shortage protection method provided by the embodiment, the first temperature protection threshold value of the radiator corresponding to the environmental temperature value of the environment where the humidifier is located is obtained by searching the first corresponding relation table, the problem that the humidifier is subjected to water shortage protection in a high-temperature environment and the humidifier is not protected when the humidifier is at a low temperature due to the fact that the same temperature protection threshold value is set at different environmental temperatures is effectively solved, and the method is simple, convenient and reliable and can be used for protecting the humidifier from water shortage in time.
In this embodiment, before the obtaining the first temperature protection threshold of the heat sink that matches the ambient temperature value of the environment where the humidifier is located, the method further includes:
s20, judging whether the temperature transformation quantity between the environment temperature value acquired at the current sampling moment and the environment temperature value acquired at the previous sampling moment is smaller than a preset temperature difference threshold value or not;
and S40, when the temperature transformation amount is larger than or equal to a preset temperature difference threshold value, executing the operation of acquiring a first temperature protection threshold value of the radiator matched with the ambient temperature value of the environment where the humidifier is located.
Specifically, in the process of working the water level of the humidifier from a high water level state to a low water level state, if the ambient temperature value changes from high temperature to low temperature suddenly, if the air conditioner is turned on in hot summer to cool the ambient temperature from high temperature to low temperature, the first temperature protection threshold value will change suddenly along with the reduction of the ambient temperature value, because the radiator is used for cooling the controller and the atomizing element, the first temperature value on the surface of the radiator is derived from the fact that the controller works and the atomizing element works to cause the temperature of the radiator to rise, the sensitivity of the first temperature value affected by the ambient temperature is low, namely, the change rate of the first temperature value is far smaller than the temperature change rate of the ambient temperature value. At this time, the refreshed first temperature protection threshold may be smaller than the first temperature value at this time, so that the water level of the humidifier is suddenly protected if the water level of the humidifier has not reached the low water level.
On the other hand, in the process that the water level of the humidifier works from a high water level state to a low water level state, if the ambient temperature value suddenly changes from low temperature to high temperature, for example, when other warm air devices such as an air conditioner and the like are turned on in cold winter, the first temperature protection threshold value suddenly increases along with the sudden increase of the ambient temperature value, at this moment, a second temperature protection threshold value with high temperature refreshed again may be far higher than the first temperature value of the radiator at this moment, and even if the water level at this moment is close to the low water level state, the humidifier cannot be protected from water shortage, and the humidifier is burnt dry.
Detecting the variation of the environmental temperature value, judging that the environmental temperature value does not have mutation when the variation does not exceed a preset temperature difference threshold, and determining a first temperature protection threshold according to the environmental temperature value; when the variation exceeds the preset temperature threshold, the environment temperature value is judged to be suddenly changed, and the humidifier cannot be protected from water shortage through the first temperature protection threshold determined by the environment temperature value.
Generally, the preset temperature threshold may be 1 ℃ to 5 ℃, the preset temperature threshold is set and configured in the controller before the humidifier leaves a factory, a value range of the temperature threshold may also be determined by experiments, and the present application is not particularly limited.
According to the humidifier water shortage protection method provided by the embodiment of the invention, when the environment temperature value does not suddenly change, the first temperature protection threshold value is determined according to the environment temperature value, so that the reliability of water shortage protection is improved, and the technical problem that the humidifier cannot carry out water shortage protection due to the fact that the same temperature protection threshold values are set at different environment temperatures is effectively solved.
In this embodiment, the method further includes:
s50, when the temperature transformation amount is larger than or equal to a preset temperature difference threshold value, judging whether a first temperature value of the radiator is larger than or equal to a preset second temperature protection threshold value or not, wherein the second temperature protection threshold value is smaller than the first temperature protection threshold value;
s60, if the first temperature value is larger than or equal to a preset second temperature protection threshold value, matching the remaining service time of the water in the water tank according to the temperature difference between the first temperature value and the second temperature protection threshold value;
and S70, performing water shortage protection according to the remaining service life. And when the running time of the humidifier is longer than or equal to the residual using time of the water in the water tank, controlling the humidifier to perform water shortage protection.
In the operation process of the humidifier, the ambient temperature value of the environment where the humidifier is located is 35 ℃, the humidifier is operated from a high water level state to a low water level state, the corresponding first temperature protection threshold value is 75 ℃ at the ambient temperature, and the corresponding second temperature protection threshold value of the low water level state is 70 ℃. When the environmental temperature value is changed from 35 ℃ to 20 ℃, for example, when an air conditioner is started, at this time, the first temperature protection threshold corresponding to the environmental temperature value of 20 ℃ is suddenly changed to 60 ℃, if the second temperature protection threshold is not set, the first temperature value of 70 ℃ corresponding to the humidifier in the next low water level state is already greater than the first temperature protection threshold at this time, the humidifier immediately starts protection, and actually, the water in the water tank does not reach the low water level state, so that the false protection is caused.
In this embodiment, the preset second temperature protection threshold is smaller than the first temperature protection threshold, and the water level in the water tank corresponding to the second temperature protection threshold is in the high water level state and the low water level state, that is, the water level in the water tank corresponding to the second temperature protection threshold is determined as the second low water level state. When the sudden change of the environmental temperature is detected, if the first temperature value of the radiator is larger than or equal to the preset second temperature protection threshold value, the water level in the water tank is in a low water level state or below the low water level state, and the humidifier cannot be effectively subjected to water shortage protection through the first temperature protection threshold value, so that the humidifier is subjected to water shortage protection by directly adopting the residual service time of water in the water tank.
Optionally, the second temperature protection threshold is 5 ℃ to 10 ℃ lower than the first temperature protection threshold. When the temperature difference value between the first temperature value and the second temperature protection threshold value is 0 ℃, the water level in the water tank is indicated to be in a low water level state, and the residual service time is the time for the low water level state to be consumed; the larger the temperature difference between the first temperature value and the second temperature protection threshold value is, the closer the water level in the water tank is to the low water level state is indicated, and correspondingly, the smaller the residual service life is, namely, the temperature value is in an inversely proportional relation with the residual service life of the water in the water tank.
Specifically, the matching of the remaining service time of the water in the water tank according to the temperature difference value specifically includes:
calculating a temperature difference value between the first temperature value and a second temperature protection threshold value;
and searching the residual service time of the water in the water tank matched with the temperature difference according to a preset second corresponding relation table, wherein the second corresponding relation table comprises the corresponding relation between the temperature difference and the residual service time of the water in the water tank.
Further, the method further comprises:
and if the first temperature value is smaller than a preset second temperature protection threshold value, controlling the humidifier to execute the operation of acquiring the first temperature protection threshold value of the radiator matched with the environment temperature value of the environment where the humidifier is located.
According to the water shortage protection method for the humidifier, when sudden change of the environment temperature is detected, whether the water level in the water tank is between the low water level state and the low water level state is determined by comparing the magnitude relation between the first temperature value and the preset second temperature protection threshold value, and if the water level is between the low water level state and the low water level state, water shortage protection is carried out on the humidifier according to the remaining service time; if the water level is between the low water level state and the high water level state, the water in the water tank has enough time to adapt to the change of the environmental temperature, so that the water shortage protection can be carried out on the humidifier according to the first temperature protection threshold value, and the method can effectively protect the humidifier.
