Fig. 1-2 are schematic structural views of a humidifier shown according to an exemplary embodiment; 3-5 are flow diagrams illustrating a method of bubble detection of a humidifier according to an exemplary embodiment; fig. 6-7 are flow diagrams illustrating a method of foam removal for a humidifier according to an exemplary embodiment.
In some alternative embodiments, as shown in fig. 1, there is provided a humidifier comprising a cartridge 1, a water level sensor 2 disposed on the cartridge 1, and a controller, wherein:
the water level sensor 2 is used for detecting whether the water level in the barrel 1 rises to a preset height;
the controller is used for: when the water level sensor 2 detects that the water level in the barrel body 1 rises to a preset height, acquiring water inlet time from the beginning of water inlet of the barrel body 1 in an empty barrel state to the time when the water level in the barrel body 1 rises to the preset height; and judging whether foam exists in the cylinder body 1 according to the relation between the water inlet time and the preset water inlet time.
Alternatively, the preset height may be the height of the position at the highest water level inside the drum 1. The water level sensor 2 may be disposed at a highest water level position in the cylinder 1, and when the water level sensor 2 detects that the water level in the cylinder 1 rises to the highest water level position, the judgment result information that the water level in the cylinder 1 rises to a preset height is transmitted to the controller. The timer in the controller starts timing from the beginning of water filling to the barrel body 1 in an empty barrel state, the timer stops timing after the controller receives judgment result information sent by the water level sensor 2, and the timing time of the timer is water inlet time. Here, the preset water inlet time is pre-stored in the controller, and is the water inlet time from the beginning of water inlet from the empty barrel 1 to the rising of the water level in the barrel 1 to the preset height when no foam is present in the barrel 1.
When foam exists in the cylinder body 1, the foam is conductive and floats on the water surface, and the foam can trigger the water level sensor 2 before the water surface, so that the water inlet time is shortened relative to the water inlet time when no foam exists in the cylinder body 1. Therefore, whether foam exists in the cylinder 1 can be judged according to the relation between the water inlet time and the preset water inlet time.
When t1< t0, determining that foam exists in the cylinder 1; when t1 ≧ t0, it is determined that no foam is present in the cylinder 1.
Here, t1 is the water inlet time, and t0 is the preset water inlet time.
Thus, when the water level sensor 2 detects that the water level in the humidification cylinder 1 rises to the preset height, whether foam exists in the cylinder 1 is judged according to the relation between the water inlet time and the preset water inlet time, and the function of automatically detecting whether foam exists in the humidification cylinder 1 of the humidifier can be realized.
In some alternative embodiments, as shown in fig. 1, the humidifier further comprises a heating electrode 3 and a current transformer 4, wherein:
the heating electrode 3 is used for heating by taking water in the cylinder 1 as a conductive medium;
the current transformer 4 is used for detecting the current of the heating electrode 3;
the controller is further configured to: when the water inlet time is shorter than the preset water inlet time, the current of the heating electrode 3 detected by the current transformer 4 is obtained; and judging whether foam exists in the cylinder 1 according to the relation between the current and the preset current.
Here, the preset current is pre-stored in the controller, and is the current between the two heating electrodes 3 when there is no foam in the cylinder 1. The humidifier is an electrode type humidifier. Two heating electrodes 3 are provided in the cylindrical body 1, and after energization, heat is generated between the electrodes by using water in the cylindrical body 1 as a conductive medium, and the temperature is raised to a boiling state for humidification. When foam exists in the cylinder 1, gas exists in the foam, so that the effective contact area between water and electrodes is reduced, and the conductive current between the two heating electrodes 3 is reduced. Therefore, whether the foam exists in the cylinder 1 can be judged according to the relation between the current and the preset current.
When I1< I0, determining that foam exists in the cylinder 1; when I1 ≧ I0, it is determined that no foam is present in the cylinder 1.
Here, I1 is the current magnitude, and I0 is the preset current magnitude.
Therefore, on the basis of taking the water inlet time as a judgment condition for judging whether foam exists in the cylinder body 1, the current is further taken as a judgment condition for judging whether foam exists in the cylinder body 1, so that the foam in the cylinder body 1 can be accurately detected, and the accuracy of foam detection is improved.
In some alternative embodiments, as shown in fig. 2, the water level sensor 2 includes a first water level sensor 21 provided at a first height position of the drum 1 and a second water level sensor 22 provided at a second height position of the drum 1, wherein:
the first water level sensor 21 is used for detecting whether the water level in the cylinder 1 rises to a first height position;
the second water level sensor 22 is used for detecting whether the water level in the drum 1 rises to a second height position;
the height of the first height position is less than the height of the second height position;
the controller is further configured to: when the first water level sensor 21 detects that the water level in the barrel body 1 rises to the first height position, acquiring first water inlet time from the beginning of water inlet of the barrel body 1 in an empty barrel state to the time when the water level in the barrel body 1 rises to the first height position; when the second water level sensor 22 detects that the water level in the drum body 1 rises to the second height position, acquiring second water inlet time from the beginning of water inlet of the drum body 1 in an empty drum state to the time when the water level in the drum body 1 rises to the second height position; when the first water inlet time is shorter than the preset first water inlet time and the second water inlet time is shorter than the preset second water inlet time, acquiring a first water inlet time difference between the first water inlet time and the preset first water inlet time and a second water inlet time difference between the second water inlet time and the preset second water inlet time; and judging whether foam exists in the cylinder body 1 according to the relation between the first water inlet time difference and the second water inlet time difference.
Here, the preset first water inlet time is pre-stored in the controller and is the water inlet time from the beginning of water inlet of the barrel 1 in an empty barrel state to the rising of the water level in the barrel 1 to a first height position when no foam exists in the barrel 1; the preset second water inlet time is pre-stored in the controller and is the water inlet time from the beginning of water inlet of the barrel body 1 in an empty barrel state to the rising of the water level in the barrel body 1 to the second height position when no foam exists in the barrel body 1.
Generally, when foam exists in the cylinder 1, the foam gradually increases along with the increase of water inflow in the cylinder 1, so that the first water inflow time difference is smaller than the second water inflow time difference. Therefore, it is possible to determine whether or not foam is present in the cylinder 1 based on the relationship between the first water inflow time difference and the second water inflow time difference.
When Δ t1< Δ t2, it is determined that foam is present in the cylinder 1; when Δ t1 ≧ Δ t2, it is determined that no foam is present in the cylinder 1.
Here, Δ t1 is the first water intake time difference, and Δ t2 is the second water intake time difference.
Like this, on the basis of the judgement condition whether having the foam with the time of intaking as the judgement in judging barrel 1, according to the nature that the foam produced, with the time difference of intaking as the judgement condition whether having the foam in further judging barrel 1, can realize the accurate detection of foam in the barrel 1, improve the accuracy that the foam detected.
In some optional embodiments, the water inlet time, the current magnitude, and the water inlet time difference may be used as the determination conditions for determining whether the foam exists in the cylinder 1, so as to further improve the accuracy of the foam detection of the humidifier.
