The embodiments described below with reference to the accompanying drawings are illustrative only for the purpose of explaining the present invention, and are not to be construed as limiting the present invention.
In the description of the present invention, it is to be understood that the terms "upper", "lower", "top", "inner", "outer", and the like, indicate orientations or positional relationships based on those shown in the drawings, are merely for convenience in describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a particular orientation, be constructed in a particular orientation, and be operated, and thus, should not be construed as limiting the present invention.
The structure of a humidifier 100 according to an embodiment of the present invention is described below with reference to fig. 1.
According to a humidifier 100 of an embodiment of the present invention, as shown in fig. 1, the humidifier 100 includes: a casing (only a bottom cover 3 of the casing is shown in figure 1) and a plurality of humidifying units 1 and water storage tanks 2 arranged in the casing. In the description of the present invention, "a plurality" means two or more unless otherwise specified.
In some embodiments, the humidifier 100 is adapted to be installed in a kitchen or toilet to facilitate water replenishment and drainage. Humidifier 100 hoists on the roof of kitchen or bathroom, and casing internals all connects on the lateral wall of casing or roof, and the inside heavier part of this kind of humidifier 100 all is located casing mounting point lower department, and the moment of torsion that produces when receiving external impact is little, and humidifier 100 is difficult to rock. Optionally, storage water tank 2 and humidification unit 1 all connect on the roof of casing, in case in this way after the hoist and mount of casing top are accomplished, whole structure smoothness, security are all higher. The shell is provided with a bottom cover 3, and the bottom cover 3 is a detachable cover body, so that the cover is conveniently detached from the lower part for maintenance.
Specifically, the water storage tank 2 has a water inlet 21 for connecting with an external water source inside the housing, and the external water source performs automatic water replenishment from the water inlet 21 when the water level inside the water storage tank 2 is low, or a user manually adds water to the water inlet 21, so as to ensure that the water storage tank 2 can provide sufficient humidification water for each humidification unit 1.
As shown in fig. 1, each humidification cell 1 includes water boiling containers each having an air outlet 11. The air outlet 11 is used for outputting steam to the space to be humidified. Each water boiling vessel has a water replenishment port 12 for connection to the water storage tank 2. The water stored in the water storage tank 2 can be guided into each water boiling container through the water replenishing port 12, and each humidifying unit 1 does work on the water to vaporize and output the water.
The humidifier 100 of the present invention may be a steam type humidifier, a wet film humidifier or an ultrasonic humidifier, which is not limited herein. The operation principle of the humidification unit 1 will be described below by taking the humidifier 100 for steam humidification as an example.
In some examples of the present invention, a PTC heating element is disposed in the water boiling container of the humidification unit 1 to heat the water inside the container, so that the water is rapidly evaporated and boiled, and the generated steam is output from the air outlet 11. The heating power of the PTC heating element does not change greatly along with the change of the input voltage. When the PTC heaters are used for heating, each heating member may be provided to include a plurality of PTC heaters, and the heating power of the heating member is changed by changing the number of the PTC heaters that are turned on at a time.
As can be seen from the above structure, in the humidifier 100 according to the embodiment of the present invention, the steam output from the air outlet 11 of each humidification unit 1 may respectively correspond to different humidification spaces or different positions of the same humidification space, so as to meet various humidity requirements.
For example, the number of rooms to be serviced by the humidifier 100 is four, and the humidifier 100 has four humidification units 1, and the operation parameters of the four humidification units 1 can be adjusted according to the humidity requirements of different rooms.
For another example, the humidifier 100 may serve a laboratory that requires different air flows and humidity at different locations, and the plurality of humidification units 1 may adjust the operation parameters according to the humidity requirements at different locations in the same laboratory.
Also for example, where multiple humidification cells 1 of humidifier 100 each release vapor at the same location, humidifier 100 may select one or more of humidification cells 1 to operate simultaneously in producing gas during use.
The PTC heating elements in the plurality of humidifying units 1 can be controlled to humidify, and the humidifying conditions can be changed by adjusting the number of the PTC heating elements in each humidifying unit 1, so that the humidifying conditions can be quickly formed into the required humidifying conditions, and the space to be humidified can quickly reach the preset humidity value.
In some embodiments, a water level sensor is provided in the humidification unit 1 to detect the water level, and when the water level in the humidification unit 1 is lower than a set value, the water in the water storage tank 2 is replenished to the humidification unit 1.
In some embodiments, a temperature sensor is disposed in the humidifying unit 1, and the temperature sensor can detect the temperature of the water inside in real time to indirectly determine whether the heating power setting of the heating element is appropriate or not and whether the adjustment is needed or not.
Advantageously, the air outlet 11 is located at the upper part or top of the humidifying unit 1 to avoid water in the container from being discharged along the air outlet 11, and to facilitate the outward conduction of the generated steam by utilizing the upward rising characteristic of the steam.
Advantageously, the water replenishment port 12 is located in the lower part of the humidification unit 1. This is because if the position of the water replenishing port 12 is higher than the liquid level in the water storage tank 2, it is not favorable for the humidifying unit 1 to replenish water by using the liquid level difference between the water replenishing port 12 and the water storage tank 2, and the excessively high water replenishing port 12 needs to be supplemented by a pump, which is high in cost. Therefore, in the embodiment of the present invention, the water replenishing port 12 is disposed at the lower portion of the humidification unit 1, and a pump may not be provided, thereby reducing the water replenishing cost.
A detailed description will be given of a specific control method of the humidifier 100 according to the embodiment of the present invention.
According to the control method of the humidifier 100 of the embodiment of the invention, as shown in fig. 2, the humidifier 100 includes a plurality of PTC heating elements, and the humidifier 100 adjusts the operating position by adjusting the number of the PTC heating elements that are turned on.
When the humidifier 100 has been operated for at least one cycle, the operation level of the humidifier 100 in the present cycle is adjusted according to the operation time of the humidifier 100 in the previous cycle and the operation time of the humidifier 100 in the present cycle.
It should be noted that "one cycle" refers to a period of time from the start of the production of the steam to the stop of the production of the steam by the humidifier 100.
It will be appreciated that the humidifier 100, when initially operated, produces a vapor at a rate that substantially corresponds to the humidification rate described in the product specification. However, after the humidifier 100 is used, various components, especially functional components (such as a heating element, an ultrasonic generator, etc.) generating steam are more or less affected, for example, heat transfer efficiency is reduced due to scaling on the surface of the functional components, and heat generation amount per unit time is increased due to changes in the electrical conductivity of the material. However, the influence of the functional components on the steam generation speed is unpredictable as the use condition changes, so that during each cycle of operation, the number of the PTC heaters of the humidifier 100 in the cycle is adjusted according to the number of the PTC heaters of the humidifier 100 in the previous cycle, the operation time of the humidifier 100 in the previous cycle, and the operation time of the humidifier 100 in the present cycle, so that the operation power obtained in the present cycle is more suitable for the operation of the humidifier 100. This method of adjusting the humidification operation power is a self-adjustment of the humidifier 100 by the influence of the humidifier itself as the number of times of use increases.
Therefore, the adjustment of the humidifying operation power of the humidifier 100 can be more accurate and faster, and the adjustment can be more adaptive to the change rule of the humidifier. Moreover, each humidifier 100 is subjected to different environmental influences after being used for multiple times due to different use environments, and the work-doing capability of each humidifier 100 after being operated for multiple times is changed, so that the parameters adjusted by the method are more adaptive to the conditions, and the adaptability of the power adjustment of the humidifier 100 is realized.
According to the control method of the humidifier 100 provided by the embodiment of the invention, when the humidifier 100 is started again after at least one operation period in the operation process, the power of the humidifier 100 in the operation process in the period can be rapidly adjusted according to the humidification condition of the previous period, particularly the operation duration, and the self-adaptive adjustment of the change of the power of the humidifier 100 on the self-acting capacity can be realized.
In the embodiment of the invention, the humidifier 100 adjusts the operation condition of the previous period in the humidification process, so that the adjustment is quick, and the adjustment time required by the operation power in the current humidification period is greatly shortened. The humidification power is suitable, the current operation power of the humidifier 100 is not too large or too small (the number of the PTC heating elements is not too large or too small), the humidifier 100 does not need to frequently operate to adjust humidification conditions, the user experience is good, and the humidification is closer to the ideal humidification conditions after a plurality of humidification operations.
In some embodiments, if the humidifier 100 is turned on for the first time, when the humidifier 100 operates in the first period, all the PTC heaters in the humidifier 100 are turned on until the indoor humidity reaches the target humidity, the operation duration of the humidifier 100 and the number of turned-on PTC heaters (operating positions) in the first period are recorded, and then the operation duration of the humidifier 100 in the first period is used as a consideration parameter for adjusting the operating positions of the humidifier 100 in subsequent periods. When the humidifier 100 is operated for the second period, operation at full power or reduced power continues.
In some embodiments of the present invention, as shown in fig. 2, when the operating position of the humidifier 100 is adjusted in the present cycle, the number of the PTC heaters turned on in the previous cycle is taken as a basic number: and determining the running power of the period by judging the relation between the running time required by the previous period and the preset time range. The specific control method comprises the following steps:
when the operation time of the humidifier 100 in the previous cycle is within the preset time range, the humidifier 100 in the previous cycle is operated at the working gear of the humidifier 100, and the number of the PTC heaters to be turned on in the previous cycle is equal to the number of the bases. That is, during the humidification process, the operation position and the operation time of the humidifier 100 in the previous cycle are appropriate, and the humidification condition does not need to be adjusted in the present cycle, but the humidification is continued on the basis of the previous cycle.
When the operation time of the humidifier 100 in the previous period is longer than the preset time range, the number of the PTC heaters to be turned on is increased on the basis of the number in the current period, and the working gear of the humidifier 100 is adjusted upwards. That is, the working position of the humidifier 100 in the previous period is too small, so that the operation time of the previous period is too long, and the humidification condition needs to be adjusted in this period, and the working position is adjusted up and humidified in this period.
When the operation time of the humidifier 100 in the previous period is shorter than the preset time range, the number of the PTC heaters to be turned on is reduced on the basis of the number in the current period, and the working gear of the humidifier 100 is adjusted below. That is, the previous cycle has a relatively large operating range of the humidifier 100, so that the previous cycle has a relatively short operating time, and if the humidifier continues to be humidified at a relatively large operating power, the service life of the humidifier 100 is easily damaged, and therefore, the operating range of the humidifier 100 is adjusted downward in the current cycle, so that the operating time of the current cycle is closer to the preset time.
Namely, the method for adjusting the specific operating conditions of the current cycle can ensure that the working gear of the current cycle is not too large or too small, thereby ensuring enough operating power and enough safe operating power during operation and ensuring that the operating time is within a reasonable range.
In addition, the preset time range can be set reasonably according to the volume of the humidification space, the indoor and outdoor humidity difference of the humidification space, the safe humidification voltage of the humidification unit, and other conditions.
In some embodiments of the present invention, when the working position of the humidifier 100 in the present period is adjusted, the adjustment is performed according to the operation duration of the humidifier 100 in the previous period on the basis of the working position of the humidifier 100 in the previous period; then, on the basis of the adjusted gear, the operating time of the humidifier 100 in the present period is adjusted until the indoor detected humidity reaches the set target humidity.
That is, when the operating power of the present cycle is adjusted, the operating conditions of the previous cycle and the operating conditions of the present cycle are considered. The humidifier can be adjusted once according to the previous working gear to obtain a proper working gear for humidification so as to achieve the indoor target humidity, and in the preset operation time, the humidifier 100 only needs to enable the indoor humidity to achieve the target humidity through the same working gear and working time for multiple times, and the humidifier 100 does not need to be repeatedly turned on and off during the period.
It is also possible that the operation position and the operation time of the cycle are gradually adjusted in a plurality of cycles and the operation position and the operation time of the cycle are not adjusted in place at a time, until the indoor humidification reaches the target humidity, during which the humidifier 100 does not need to be repeatedly turned on and off.
In some embodiments, a humidity detector is disposed in the room or the target space to be humidified, and the humidity detector measures the humidity, and combines and compares the indoor real-time humidity value with the operating gear adjustment of the humidifier 100, that is, during the operation of the humidifier 100, the end point of the operation of the humidifier 100 is determined as the indoor humidity value reaching the preset humidity value.
In some embodiments of the present invention, the operation of the humidifier 100 during the present cycle includes the steps of:
the method comprises the following steps: the humidifier 100 is operated in the first gear until the first condition is satisfied.
Step two: on the basis of the number of the PTC heating elements which are started in the previous period, the number of the PTC heating elements which are started is adjusted according to the operation time of the humidifier 100 in the previous period and the working time of the humidifier 100 in the previous period until the indoor detection humidity reaches the set target humidity. That is, the humidifier 100 is turned on again after being stopped, the first gear is operated in the first step to stabilize the amount of steam generated in the humidifier 100 per unit time and to output the steam stably for a short time, and the second step is adjusted based on the number of PCT heaters that were previously humidified during the second step.
Optionally, all PTC heaters in the humidifier 100 are turned on at the first gear. When all the PTC heaters are turned on, the humidifier 100 is operated at the maximum power, so that the water in the water boiling container is rapidly boiled.
When the humidifier 100 includes a plurality of humidification cells 1, the humidification power of the corresponding humidifier 100 is the maximum power when all the humidification cells 1 are turned on.
In some examples, the first condition is that water to be heated by the PTC heater starts boiling. That is, after the water starts to boil, the amount of steam can be stably generated, the time required for humidification is saved, the waiting time before the steam is generated is reduced, and then the step two is performed to adjust the number of the PTC heaters in each humidifier 100.
In some embodiments of the present invention, as shown in fig. 3, in step two (the conditioning phase), the operation of the humidifier 100 includes the following steps:
s1: the humidifier 100 begins operating in the second gear. Here, the second gear is adjusted based on the operating gear of the humidifier 100 in the previous cycle, and the specific adjustment method is as follows:
the starting number of the PTC heaters in the previous period is used as a basic number, and when the operation time of the humidifier 100 in the previous period is within a preset time range, the starting number of the PTC heaters in the second gear is equal to the basic number;
when the operation time of the humidifier 100 in the previous period is longer than the preset time range, the number of the PTC heaters which are turned on at the second gear is larger than the basic number.
When the operation time of the humidifier 100 in the previous period is shorter than the preset time range, the number of the PTC heaters which are turned on at the second gear is smaller than the basic number.
S2: setting time length every interval, comparing the indoor detection humidity with the target humidity: when the indoor detected humidity is equal to or greater than the target humidity, the humidifier 100 stops the humidification operation.
When the indoor detected humidity is lower than the target humidity, the number of the PTC heating elements is increased, and the humidifying operation is continued after the working gear of the humidifier 100 is adjusted upwards.
Optionally, when the operation duration of the humidifier 100 in the previous period is longer than the preset time range, the second gear is adjusted up to a certain number Δ N of PTC heaters based on the basic number to continue the humidification operation, and Δ N of PTC heaters are adjusted up at the same time interval until the indoor detected humidity reaches the target humidity.
Optionally, when the operation duration of the humidifier 100 in the previous period is longer than the preset time range, the number of the PTC heaters of the second gear is increased by the number of the PTC heaters of different number based on the previous period to continue the humidification operation, when the difference between the indoor humidity value and the target humidity value is larger and the difference between the indoor humidity value and the previous period operation time is larger than the preset time range, then when the power is adjusted in the present period, the number of the PTC heaters which are initially increased is larger, and then the number of the PTC heaters which are increased every certain time is gradually decreased until the target humidity value is reached.
Similarly, when the operation time of the humidifier 100 in the previous period is shorter than the preset time range, the second gear is adjusted down by a certain number Δ N of PTC heaters based on the basic number to continue the humidification operation, and Δ N of PTC heaters are adjusted down at the same time interval until the indoor detected humidity reaches the target humidity.
Optionally, when the operation duration of the humidifier 100 in the current period is less than the preset time range, the number of the PTC heaters of different numbers is decreased by the second gear from the base number of the previous period to continue the humidification operation, when the difference between the indoor humidity value and the target humidity value is large and the difference between the indoor humidity value and the previous period operation time and the preset time range is large, then when the power is adjusted in the current period, the number of the PTC heaters which are initially decreased is large, and then the number of the PTC heaters which are decreased at certain intervals is gradually decreased until the target humidity value is reached.
