Detailed Description
The present invention first provides a control method of an air treatment device for an air conditioner, fig. 1 is a schematic configuration view of an air treatment device according to one embodiment of the present invention, and fig. 2 is a schematic sectional view of an air treatment device according to one embodiment of the present invention.
Referring to fig. 1 and 2, the air treatment device 1 of the present invention includes a housing 10. The housing 10 is provided with an air inlet and an air outlet 13. The air outlet 13 is used for communicating with the indoor. In a specific embodiment, the number of the air inlets can be one, and the air inlets can be communicated with the indoor space or the outdoor space. In another specific embodiment, the number of the air intakes may also be two or more, for example, in the embodiment shown in fig. 1, the number of the air intakes is two, and it includes an indoor air intake 11 for communicating with the indoor space and an outdoor air intake 12 for communicating with the outdoor space to introduce fresh air. The indoor air inlet 11 and/or the outdoor air inlet 12 can be selectively opened or closed by a damper, so as to selectively allow indoor return air and/or outdoor fresh air to enter the air processing device 1, and the air is processed by the air processing device 1 and then sent out.
It should be noted that the indoor space in the embodiment of the present invention means an indoor environment space where the air processing device 1 is located, and the outdoor space in the embodiment of the present invention means an outdoor environment space.
An air duct communicating the air inlet and the air outlet 13 is formed in the housing 10, and a fan 21 for driving air flow to flow from the air inlet to the air outlet 13, a water storage tank 31 for containing water, a water tank heating device 33 arranged in the water storage tank 31, and a washing device 40 for washing, purifying and humidifying the air flow in the air duct by using the water in the water storage tank 31 are arranged in the air duct. In particular, the water wash apparatus 40 may be used to urge water in the water storage tank 31 into contact with the airflow. When the airflow contacts with water, pollutants such as impurities, floccules, water-soluble harmful gases and the like in the airflow are dissolved in the water, so that the water washing and purification of the airflow are realized. Meanwhile, the air flow can also carry away part of water vapor, thereby realizing the humidification of the air flow.
Fig. 3 is a schematic flowchart of a control method of an air treatment device according to a first embodiment of the present invention. The control method of the present invention may include:
step S40, when the air processing apparatus 1 is in the water washing mode, determining whether a preset heating start condition is satisfied; if the heating starting condition is met, turning to step S40; wherein, in the water washing mode, the water washing device 40 is in an operating state; if the heating starting condition is not met, the heating starting condition is kept unchanged.
Step S50, the water tank heating device 33 is activated to heat the water in the water storage tank 31 to raise the temperature of the water, so that at least a portion of the heat is transferred from the water to the air stream when the water contacts the air stream, thereby raising the temperature of the air stream.
That is to say, this application develops the heating of air current into the heating of water in a new way for purification, humidification, the intensification of air current all go on simultaneously when air current and water contact, and the realization of three kinds of functions does not influence each other, can not only carry out humidification and washing purification to the air effectively, can compensate air temperature again, supplementary air conditioner heating.
In some embodiments, the heating start condition may include the air conditioner being in a heating mode and/or the temperature of the air stream in the duct upstream of the water wash device 40 being lower than the room temperature at which the air conditioner is located. Specifically, the temperature of the air flow in the air duct upstream of the water washing device 40 may be, for example, the temperature of the air flow at the air inlet.
Fig. 4 is a schematic flowchart of a control method of an air treatment device according to a second embodiment of the present invention. In some embodiments, before determining whether the preset heating start condition is satisfied, the control method of the present invention further includes:
step S31, acquiring the height of water in the water storage tank 31 after the air treatment device 1 is turned on; and
in step S32, the water washing device 40 is activated when the height of the water in the water storage tank 31 reaches a preset height, so that the air treatment device 1 enters a water washing mode.
That is, the water washing device 40 is activated only when the water amount in the water storage tank 31 is sufficient, so as to cause the air treatment device 1 to enter the water washing mode, thereby ensuring good purification effect and humidification effect in the water washing mode. This is because if there is too little water in the storage tank 31, it is not ensured that the water wash apparatus 40 will be able to bring sufficient water into contact with the air stream, thus severely affecting the air stream purification and humidification.
Further, when the height of the water in the water storage tank 31 is lower than the preset height, a prompt signal for prompting to add water into the water storage tank 31 can be sent.
Fig. 5 is a schematic flowchart of a control method of an air treatment device according to a third embodiment of the present invention. In some embodiments, the intake vent may include an outdoor intake vent 12 for communicating with the outdoor. In these embodiments, referring to fig. 4, before obtaining the water level in the water storage tank 31, the control method of the present invention further includes:
step S21, judging whether the preset fresh air starting condition is met; if yes, go to step S22; if not, the data is kept unchanged.
Step S22 is to start the air treatment device 1 to open the air inlet and the air outlet, so that the blower 21 is started to operate.
That is to say, when outdoor fresh air is introduced into the room through the outdoor air inlet 12, the impurities and harmful gases in the outdoor fresh air are more in types and amounts, so that the quality of the indoor air can be effectively improved by using the air processing device 1 of the present application to wash, purify and humidify the outdoor fresh air and then inputting the outdoor fresh air into the room.
Further, the fresh air starting condition may include receiving an indication signal for indicating introduction of fresh air into the room and/or detecting that the indoor air quality index exceeds a preset index. That is, the air treatment device 1 may be started when a fresh air introduction instruction signal sent by a user is received, or the air treatment device 1 may be automatically started when an indoor air quality index exceeds a standard and outdoor fresh air needs to be introduced.
Specifically, the indoor air quality index may include the concentration or content of various gases, such as carbon dioxide, formaldehyde, benzene, and the like.
Fig. 6 is a schematic flowchart of a control method of an air treatment device according to a fourth embodiment of the present invention. In some embodiments, after activating the tank heating device 33, the control method of the present application further includes:
step S60, acquiring the temperature of the water in the water storage tank 31 in real time or periodically;
step S70, the power of the tank heating means 33 is adjusted according to the temperature of the water in the storage tank 31 so that the water in the storage tank 31 is kept at a constant temperature.
Therefore, the temperature of the air flow sent to the room through the air treatment device 1 can be kept constant approximately, and the phenomenon that the air conditioner adjusts the operation parameters due to the change of the temperature of the air flow sent by the air treatment device 1 is reduced.
In some embodiments, the water washing device 40 includes a drum rotatably disposed in the water storage tank 31 to take out water in the water storage tank 31 by rotation of the drum and to wash, purify and humidify the air flow by the taken-out water as the air flow passes through the drum. Specifically, when the roller rotates, the water in the water storage tank 31 can be taken out, and when the air flow passes through the roller, the air flow can be contacted with the water taken out from the roller, so that the purposes of water washing, purification and humidification of the air flow are achieved. This application utilizes water and the air current contact that carries on the cylinder to the cylinder is pivoted, compares the water curtain that forms among the prior art, and the mode of the water and the air current contact of this application can not produce great resistance to the air current, has reduced the influence to the air current velocity of flow.
In these embodiments, the applicants have recognised that the gas stream is also humidified whilst being purified by the water wash, the degree to which the gas stream is humidified being closely related to the amount of water in contact with the gas stream, the time of contact of the gas stream with the water, etc. The amount of water in contact with the air flow depends on the speed of rotation of the drum, and the length of time for which the air flow is in contact with the water depends on the speed of rotation of the fan 21.
To this end, in some embodiments, referring to fig. 7, fig. 7 is a schematic flow chart of a control method of an air treatment device according to a fifth embodiment of the present invention, the control method of the present application further including:
step S80, when the air processing apparatus 1 is in the water washing mode, acquiring the indoor humidity of the indoor environment in which the air processing apparatus 1 is located; and
and step S90, adjusting the rotating speed of the roller and/or the rotating speed of the fan 21 according to the indoor humidity, wherein the rotating speed of the roller and the indoor humidity are in inverse correlation, and the rotating speed of the fan 21 and the indoor humidity are in positive correlation.
That is, the lower the indoor humidity, the higher the speed of rotation of the drum, the more water it brings out per unit time for contact with the airflow, and the higher the degree to which the airflow is humidified. The rotation speed of the drum can be suitably reduced when the indoor humidity is high, and the slower the drum rotates, the less water it brings out per unit time for contacting the air flow, and the lower the degree to which the air flow is humidified. Therefore, the control method not only can clean and purify the air flow, but also can effectively control the humidity of the air flow. Similarly, when the indoor humidity is low, the rotation speed of the fan 21 may be appropriately reduced, and the smaller the rotation speed of the fan, the higher the degree of humidification of the air flow. When the indoor humidity is higher, the rotating speed of the fan 21 can be properly increased, the larger the rotating speed of the fan is, the shorter the contact time of the air flow and the water on the roller is, and the lower the humidifying degree of the air flow is.
Therefore, the control method can not only clean and heat the air flow, but also effectively control the humidity of the air flow.
It is understood that steps S80 and S90 may be executed before step S40, after step S50, or between any other steps, that is, there is no sequential restriction between the cleaning of the drum and the heating of the water in the water storage tank 31.
In some embodiments, the water washing device 40 includes a drum rotatably disposed in the water storage tank 31 to take out water in the water storage tank 31 by rotation of the drum and to wash, purify and humidify the air flow by the taken-out water as the air flow passes through the drum.
In these embodiments, referring to fig. 8, fig. 8 is a schematic flow chart of a control method of an air treatment device according to a sixth embodiment of the present invention, the control method of the present application further including:
step S11, acquiring the cleanliness of the roller; and
and step S12, entering a drum cleaning mode for cleaning the drum when the cleanliness of the drum is less than a preset minimum cleanliness.
Therefore, the self-cleaning of the roller is realized, the service life of the roller is prolonged, and the roller is ensured to have good water washing and purifying capacity for a long time.
It is understood that the above steps S11 and S12 may be performed before step S21, after the air treatment device 1 enters the water washing mode, or may be performed cyclically according to a preset time period. That is, there is no restriction on the order between the above steps S11 and S12 and other steps.
Further, in the drum washing mode, the drum is in a rotating state and the blower 21 is in a stopped state. That is, when the drum is cleaned, the drum is continuously rotated, and the uniformity and the thoroughness of cleaning the drum can be improved. When the drum is cleaned, the fan 21 is stopped, that is, the air treatment device 1 does not introduce the air flow and does not send out the air flow, so that the dirt cleaned on the drum can be prevented from entering the room along with the air flow to cause secondary pollution.
The invention also provides an air treatment device 1, the air treatment device 1 of the invention comprising a housing 10. The housing 10 is provided with an air inlet and an air outlet 13.
