In the description of the present invention, the meaning of a plurality of means is one or more, the meaning of a plurality of means is two or more, and larger, smaller, larger, etc. are understood as excluding the number, and larger, smaller, inner, etc. are understood as including the number. If the first and second are described for the purpose of distinguishing technical features, they are not to be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated or implicitly indicating the precedence of the technical features indicated.

In the description of the present invention, unless otherwise explicitly limited, terms such as arrangement, installation, connection and the like should be understood in a broad sense, and those skilled in the art can reasonably determine the specific meanings of the above terms in the present invention in combination with the specific contents of the technical solutions.

In dry weather, if the air conditioner humidifies, external equipment is generally needed, the external equipment generates steam, the steam is sent to the air outlet of the volute, the cost of the scheme is high, the equipment for generating the steam needs to be newly added, and the requirements of a plurality of use occasions cannot be met. For example, if the scheme is applied to an embedded duct machine, because the embedded duct machine is installed in a ceiling, the space requirement is relatively strict, and the increase of external equipment can cause the increase of the overall size of the unit, and if the external equipment is installed independently, the beauty of home decoration is affected.

In addition, in order to achieve the heating effect of the indoor unit, the indoor unit is generally provided with an electric auxiliary heating device, high temperature is generated by the electric auxiliary heating device, and the air generated by the centrifugal wind wheel is preheated.

The air conditioner provided by the embodiment of the invention utilizes the original electric auxiliary heating device, and then the water box component is added, so that the water vapor of the water box component is atomized through the high temperature generated by the electric auxiliary heating device and then enters the indoor environment along with the airflow, and the humidifying function is realized. Of course, some air conditioners without an electric auxiliary heating device may also be provided with another electric auxiliary heating device, and the installation is not limited herein.

In addition, the air conditioner provided by the embodiment of the invention also considers that the electric auxiliary heating device is arranged in the air duct, and the heat loss possibly caused by the influence of air flow is possible, so that the working efficiency is reduced. Therefore, the air conditioner provided by the embodiment of the invention is provided with the baffle, and the baffle shields the air flow for the electric auxiliary heating device, so that the influence of the air flow on the working efficiency of the electric auxiliary heating device is reduced.

The air conditioner provided by the embodiment of the invention also considers that in other working modes without humidification, the flow of airflow can be blocked by the baffle, and the air volume is influenced to a certain extent. Therefore, the air conditioner of the embodiment of the invention sets the baffle to be adjustable, namely under the working condition that humidification is needed, the baffle can be adjusted to be in the first state, and on the projection plane perpendicular to the air outlet direction, the baffle can at least cover part of the electric auxiliary heating device, so that the baffle can shield part of air flow for the electric auxiliary heating device, and the heat taken away is reduced; under the operating mode that does not need the humidification, the baffle can be adjusted to the second state, and baffle under the second state is compared in baffle under the first state, and is littleer to the area that blocks of air current to reduce the loss of amount of wind.

It should be noted that the baffle is used for shielding the air flow for the electric auxiliary heating device, and the baffle is set to be adjustable, that is, the area for shielding the air flow is adjustable. Including but not limited to the following examples:

one is that the baffle is arranged to be a rotatable structure, the baffle can rotate around a rotating shaft, and when the baffle is in a first state, namely when the baffle rotates to a first position, the baffle can shield at least part of airflow for the electric auxiliary heating device; when the baffle is in the second state, that is to say when the baffle rotates to the second position, the windward area of baffle is less than the windward area of baffle when being in the first state, can understand that the area of baffle projection to the projection plane perpendicular to air-out direction diminishes, and the ability of keeping out the wind of baffle weakens promptly.

One is that the baffle is arranged into a movable structure, the baffle can move along a certain track, and when the baffle is in a first state, namely when the baffle moves to a first position, the baffle can shield at least part of airflow for the electric auxiliary heating device; when the baffle is in the second state, that is, when the baffle moves to the second position, the area of the baffle for the electric auxiliary heating device to shield the air flow is smaller than the area of the baffle for the electric auxiliary heating device to shield the air flow when the baffle is in the first state.

The other is to arrange the baffle into a structure capable of being folded or rolled, namely the baffle can increase or reduce the frontal area of the baffle. When the baffle is in a first state, namely when the baffle is opened for a certain area, the baffle can shield at least part of airflow for the electric auxiliary heat device; when the baffle is in the second state, namely when the baffle reduces certain area, the baffle reduces for the area that the electric auxiliary heating device sheltered from the air current to reduce the loss of amount of wind.

It should be noted that the air conditioners mentioned above include various types such as a ducted air conditioner, a ceiling air conditioner, a mobile air conditioner, a window air conditioner, and the like, and are not particularly limited.

Referring to fig. 1 to 9, an example of how to solve the above technical problem by using a rotatable baffle 204 applied to an embedded duct air conditioner indoor unit will be described in detail.

Referring to fig. 1, it can be understood that the air conditioner of the embodiment of the present invention includes a housing 101, a fan assembly 102, an indoor heat exchanger 103, and a humidifying device 104.

It can be understood that the housing 101 is provided with the air inlet 105 and the air outlet 106, the fan assembly 102 is disposed in the housing 101, the humidifying device 104 is disposed in the housing 101, and the indoor heat exchanger 103 is disposed in the housing 101, that is, the fan assembly 102, the humidifying device 104, and the indoor heat exchanger 103 are disposed in the air duct of the housing 101. Therefore, when the air conditioning indoor unit operates, the fan assembly 102 may operate to enable the air pressure at the air inlet 105 of the casing 101 to be lower than that of indoor air, the indoor air may enter the casing 101 from the air inlet 105 under the action of pressure difference, then the air exchanges heat with the indoor heat exchanger 103, and the air after heat exchange is discharged out of the casing 101 through the air outlet 106 to flow into an indoor space, so that a normal heat exchange function of the air conditioning indoor unit may be achieved.

In the embedded air duct indoor unit of the air conditioner shown in fig. 1, the air inlet 105 is disposed at the lower portion of the casing 101, the air outlet 106 is disposed at the front portion of the casing 101, and the humidifying device 104 is disposed between the fan assembly 102 and the indoor heat exchanger 103. Indoor air enters the air duct from the air inlet 105 and is blown to the indoor heat exchanger 103 under the action of the fan assembly 102, the air passes through the humidifying device 104 in the process, steam generated by the humidifying device 104 is sent to the indoor heat exchanger 103 together, heat exchange is carried out through the indoor heat exchanger 103 to form heat exchange air, and the heat exchange air is blown out to the indoor from the air outlet 106.

As shown in fig. 2, it can be understood that the humidifying device 104 includes a heating element 201 and a water box assembly 202, the heating element 201 heats the liquid in the water box assembly 202 to form steam, the water box assembly 202 is provided with an air outlet 203, and the air outlet 203 is used for discharging the steam.

Referring to fig. 2, it can be understood that, in order to better improve the heating efficiency and the air outlet efficiency, the water box assembly 202 is configured to have a notch, that is, the air outlet 203, so that the air outlet area of the steam is larger, and at the same time, it is convenient for the heating element 201 to partially extend into the water box assembly 202, to be closer to the liquid, and thus, the heating efficiency can be improved.

It should be noted that the heating element 201 may also be disposed at other positions of the water box assembly 202, such as the side or bottom of the water box assembly 202, as long as the heat generated by the heating element 201 can be transferred to the liquid in the water box assembly 202 to form steam.

When the humidifying device 104 works, the heating element 201 can heat water in the water box assembly 202, so that water vapor is generated, the water vapor can be discharged out of the water box assembly 202 through the air outlet 203, and then is discharged to an indoor space through the air outlet 106, so that the indoor air can be humidified, the humidity of the indoor air is improved, and the comfort level of a user is improved. Therefore, the function of humidifying air of the air conditioner indoor unit can be realized. Meanwhile, the humidifying device 104 is arranged in the shell 101, so that the occupied space of the indoor unit of the air conditioner is reduced, the appearance attractiveness of the indoor unit of the air conditioner is improved, and the indoor unit of the air conditioner is convenient to mount and dismount.

It can be understood that the water vapor discharged from the air outlet 203 can flow toward the air outlet 106 under the action of the blower assembly 102, and on the other hand, the water in the water box assembly 202 continuously forms the water vapor under the heating action of the heating element 201, so as to increase the pressure in the water box assembly 202, and therefore the water vapor at the air outlet 203 can also flow toward the air outlet 106 under the action of the pressure difference.

In the related art, when an ultrasonic humidifier is used for humidification, the main working principle is to use the high-frequency vibration of the atomizing plate to shatter water into fine water particles (white fog) close to 5-8 microns (PM5-PM 8). The fine mist is relatively light in weight and floats in the air. Because the contact surface area of the fine water mist particles and the air is greatly larger than that of water in a common state, the water mist can be quickly evaporated in the air, and the evaporated water mist is changed into water vapor, so that the moisture content in the air is increased, and the dry air is humidified. When a wet film humidifier is used for humidifying, the main working principle is as follows: the water in the water tank is conveyed to the water drenching device at the top of the humidifier, the water is evenly drenched to the top of the wet film, the water drenching device ensures that the water is evenly distributed on the wet film material, the water downwards permeates along the wet film material, all layers inside the wet film are drenched, and meanwhile, the water is absorbed by the wet film material to form an even water film. When the dry air passes through the wet film material, the dry air is in contact with the wet film surface in a larger area, so that a larger moisture evaporation capacity is achieved. A large amount of water molecules are sent into a space to be humidified along with wind, so that the humidity of air is increased, and the aim of humidification is fulfilled.

However, when the ultrasonic humidifier and the wet film humidifier are used, fungi such as mold are easily generated inside the ultrasonic humidifier and the wet film humidifier, so that the quality of the air after humidification is poor, and the air is not good for the body of a user. However, in the air conditioner according to the embodiment of the present invention, the humidifying device 104 heats water by using the heating element 201 to form water vapor, thereby humidifying air. It can be understood that, when the heating element 201 heats water, the heating element 201 and the water have higher temperature, so that the heating element can perform a sterilization function to a certain extent, and further improve the quality of the humidified air, which is beneficial to the health of a user. In addition, the air conditioner of the embodiment of the invention can utilize the original heating element 201, so that the original heating element 201 is not only used in a heating state, and the utilization rate of the heating element 201 is improved.

Referring to fig. 2 and 3, it can be understood that the humidifying device 104 further includes a baffle 204, the baffle 204 is disposed at one side of the heating element 201, and the baffle 204 is located in front of the heating element 201 in the air outlet direction, and the baffle 204 is driven to rotate by a power, which is described here by taking an example that the stepping motor 301 drives the baffle 204 to rotate.

When the air conditioner humidifies, in order to keep the temperature of the heating element 201 in the steam water box and prevent the wind field from taking away the heat of the water box assembly 202, the baffle 204 covers the heating element 201 through the projection of the rotary baffle 204 in the wind outlet direction of the wind field, namely the baffle 204 is adjusted to be in the first state, the amount of wind which can directly blow to the surface of the heating element 201 is reduced, and further the heat loss is reduced.

When the air conditioner is in a non-humidifying state, the projection of the rotary baffle 204 in the air outlet direction of the wind field reduces the area of the baffle 204 covering the heating element 201, even completely does not shield the heating element 201, reduces the windward area of the baffle 204, and reduces the influence of the baffle 204 on the wind field. It can also be understood that the baffle 204 is adjusted to the first state in order to shield the heating element 201 from more air flow, and the baffle 204 is adjusted to the second state in order to reduce the influence on the air flow of the whole wind field and to make the air conditioner effectively use the heat generated by the heating element 201 in the heating state.

It is understood that the baffle 204 may be a sheet metal part or a plastic part.

It can be understood that, when sheltering from heating element 201 for baffle 204, also can lead to its inside wind field, can set up wind-guiding portion (not shown in the figure) on baffle 204, wind-guiding portion can be the interior concave surface or the protruding cambered surface of setting on baffle 204, the camber of interior concave surface or protruding cambered surface is K, K satisfies 0 < K < 0.1, satisfy 0 < K < 0.1 through design K for interior concave surface or protruding cambered surface form the coanda effect, reduce the loss of the amount of wind.

The Coanda Effect (Coanda Effect) is also known as the Coanda Effect or Coanda Effect. The fluid (water or air) tends to deviate from the original flow direction and instead follow the surface of the protruding object. When there is surface friction (also called fluid viscosity) between the fluid and the surface of the object over which it flows, the fluid will follow the surface of the object as long as the curvature is not large. According to Newton's third law, a body exerts a force on a fluid that deflects, and the fluid must also exert a force on the body that deflects in the opposite direction.

Of course, the baffle 204 may also be a plane, that is, the air guiding portion is a straight plate, and the air flow is guided by rotating the baffle 204 to a certain angle.

Referring to fig. 3, it can be understood that the water box assembly 202 is provided with the water inlet 302, and the water inlet 302 is suitable for being connected with a water source, so that it can be known that the water box assembly 202 can be directly provided by an external water source, and water enters the humidifying device 104 through the water inlet 302, so that a user does not need to add water into the water box assembly 202, and the use experience of the user is improved. Of course, water can be added into the water box assembly 202 through the notch shown in fig. 2, and the water box assembly 202 can also be provided with a structure which can be taken out separately for cleaning or adding water.

Meanwhile, it can be understood that, when the humidifying device 104 works, water in the water box assembly 202 is continuously heated by the heating element 201 to form water vapor, so that the water in the water box assembly 202 is continuously reduced, and water can be directly supplied through a water source, thereby being beneficial to keeping the freshness of the water in the humidifying device 104, further being capable of improving the freshness of the water vapor generated by the humidifying device 104, and being beneficial to the health of a user. Of course, a purification device for purifying water may also be disposed between the water inlet 302 and the water supply source, for example, a filter is disposed at the water inlet 302, so as to further improve the freshness and cleanliness of the water in the humidification device 104, and further improve the freshness of the humidified air, which is beneficial to the health of the user.

In order to realize program control more accurately and control the on-off of the water flow at the water inlet 302, an electromagnetic valve (not shown in the figure) may be disposed at the water inlet 302. Also, water box assembly 202 may further include a water pump by which water is delivered to water inlet 302. Referring to FIG. 3, it will be appreciated that the water box assembly 202 further includes a level switch 304 that opens a solenoid valve at the water inlet 302 when water is to be added, passes through a filter at the water inlet 302 and the solenoid valve into the water box assembly 202, and that when a predetermined water level is reached, the level switch 304 is actuated to close the solenoid valve at the water inlet 302.

Referring to fig. 1, it can be understood that the air conditioner according to the embodiment of the present invention further includes a water pan 107, and the water pan 107 is disposed in the casing 101 and below the indoor heat exchanger 103. Referring to fig. 3, it will be appreciated that the water bucket assembly 202 is provided with a drain opening 303, and that liquid in the water bucket assembly 202 can drain through the drain opening 303, with the drained liquid flowing to the drip tray 107. In order to realize program control and control the on/off of water flow at the water outlet 303 more precisely, an electromagnetic valve (not shown in the figure) may be disposed at the water outlet 303.

The water outlet 303 is used for discharging water in the water box assembly 202 to prevent bacteria breeding caused by long-time water storage, and when the water box assembly is turned off, the electromagnetic valve is opened to discharge the water in the water box assembly 202 to the water pan 107 and discharge the water from a water outlet of the whole machine. And, after the humidification mode is finished, the water in the water box assembly 202 is discharged, so that the generation of steam can be reduced when the heating mode of the air conditioner is started and humidification is not needed.

It can be understood that the box body of the water box assembly 202 can be made of metal parts such as stainless steel, a cavity for storing water is formed by welding or pressing, and meanwhile, parts such as the water pump and the stepping motor 301 can be fixed on the box body to become main parts of the water box assembly 202.

Referring to fig. 4 and 6, it can be understood that the air conditioner includes a sealing plate 401, the sealing plates 401 are disposed on both left and right sides of the indoor heat exchanger 103, and both ends of the humidifier 104 are mounted on both the left and right sealing plates 401, which is beneficial to improving the overall sealing performance and reducing the air loss. Of course, both ends of the humidifying device 104 may be mounted on the housing 101.

Referring to fig. 5, it can be understood that the sealing plate 401 is provided with a support protrusion 501, and the support protrusion 501 is used to support the water box assembly 202. For example, the support protrusion 501 may be provided as a folded edge on the sealing plate 401, through which the water box assembly 202 is supported.

Referring to fig. 7, it will be appreciated that the flap 204 is rotated to a first position, in which the flap 204 is in a first state, the flap 204 completely blocking the flow of air to the heating element 201. It should be noted that, here, the heating element 201 partially protrudes from the box body of the water box assembly 202, and is partially located in the box body of the water box assembly 202, so the baffle 204 only needs to be able to shield the airflow for the portion of the heating element 201 protruding from the box body.

Referring to fig. 7, it can be understood that, on a projection plane perpendicular to the wind outlet direction, the baffle 204 covers the portion of the heating element 201 protruding from the water box assembly 202, and the maximum distance that the baffle 204 protrudes from the heating element 201 is L1, that is, the minimum distance from the heating element 201 to the wind field projection line is L1, and L1 is greater than or equal to 10 mm. When L1 is smaller than 10mm, the airflow is easy to accelerate the flow velocity near the heating element 201, and the heat dissipation is accelerated, and the air conditioner according to the embodiment of the present invention reasonably sets the relative position between the baffle 204 and the water box assembly 202, so that the baffle 204 shields the airflow for the water box assembly 202, and the heat dissipation is reduced.

Referring to fig. 7, it can be understood that an included angle α between the baffle 204 and the air outlet direction is less than 90 °, so that the wind force borne by the baffle 204 is reduced, and the baffle 204 can guide the air flow while shielding the air flow for the water box assembly 202, thereby reducing the air volume loss.

Referring to fig. 8, it will be appreciated that the flap 204 is rotated to a second position, in which the flap 204 is in a second state, the flap 204 does not block the flow of air directly towards the heating element 201. It should be noted that, here, the heating element 201 partially protrudes from the box body of the water box assembly 202, and is partially located in the box body of the water box assembly 202, so the baffle 204 only needs to be staggered with the portion of the heating element 201 protruding from the box body.

It can be understood that, when the baffle 204 is in the second state, the baffle 204 and the water box assembly 202 can be on a projection plane perpendicular to the air outlet direction, and the baffle 204 and the water box assembly 202 are at least partially overlapped, which is beneficial to reducing the wind receiving area of the humidifying device 104 and reducing the air loss as a whole.

Referring to fig. 8, it can be understood that the included angle β between the baffle 204 and the wind outlet direction satisfies: beta is more than or equal to 0 degree and less than or equal to 10 degrees. The closer β is to 0 °, the smaller the windward angle between the baffle 204 and the air outlet direction is, that is, the smaller the wind shielding effect of the baffle 204 is, and the air volume loss can be reduced.

Referring to fig. 8, it can be appreciated that the minimum spacing L2 between baffle 204 and water box assembly 202 is > 10 mm. Keeping the baffle 204 and the water box assembly 202 at a certain distance enables part of the airflow to flow out from between the baffle 204 and the water box assembly 202, and prevents excessive consumption of the air volume between the baffle 204 and the water box assembly 202. When the minimum distance L2 between the baffle 204 and the water box assembly 202 is less than or equal to 10mm, the airflow is not easy to flow out from between the baffle 204 and the water box assembly 202, and the speed of the airflow is fast when the airflow passes through, so that noise is easy to generate.

Referring to fig. 9, it will be appreciated that the flap 204 is pivoted to a position between the first and second positions, with the flap 204 in an intermediate position, the flap 204 being able to block a portion of the air flow directed towards the heating element 201. In the heating and humidifying mode, the baffle 204 rotates to a position between the first position and the second position, so that the heating element 201 can be partitioned, a part of the area is heated by air to meet the function of preheating the air, the temperature of the air reaches a preset requirement, and the other part of the area can be humidified to meet the requirement of humidity.

The embodiment of the invention provides a control method of an air conditioner, which is applied to the air conditioner in the embodiment. The structure or the components of the air conditioner have been described in detail in the above embodiments, and are not described herein again. Referring to fig. 10, the control method according to the embodiment of the present invention includes, but is not limited to, step S1010, step S1020, step S1030, and step S1040.

Step S1010, acquiring an indoor ambient humidity.

It can be understood that the indoor environment humidity can be detected by the humidity sensor, and the air conditioner acquires data of the humidity sensor, so as to acquire the indoor environment humidity. It should be noted that the indoor environment humidity can be detected by a humidity sensor arranged at the air inlet 105 of the indoor unit, and the detected value is obtained by conversion; the indoor environment humidity can also be detected through a humidity sensor arranged in the indoor environment, namely, the humidity sensor can be independently arranged from the air conditioner. The humidity sensor may be transmitted to the controller of the air conditioner by a wired transmission manner, or may be transmitted to the controller by an invalid transmission manner, such as WIFI or bluetooth, and the specific manner is not limited in this embodiment.

In step S1020, the set humidity of the air conditioner is acquired.

It can be understood that the set humidity of the air conditioner can be a humidity value set by a user through a remote controller or a mobile phone APP, and the set humidity of the air conditioner can also be a humidity value set by the controller intelligently according to the use habits of the user. For example, the controller of the air conditioner may set a humidity value at a certain time according to parameters such as outdoor environment humidity, indoor environment humidity, user habits, and the like, and the specific manner is not limited herein.

And step S1030, acquiring the working mode of the air conditioner.

It is understood that the operation mode of the air conditioner may be obtained by receiving a user instruction, or by other obtaining means. The user can send out the instruction through modes such as remote controller or cell-phone APP, makes the air conditioner acquire the mode. The operation mode of the air conditioner may include, but is not limited to, a heating mode, a heating and humidifying mode, a cooling and humidifying mode, and the like.

And step S1040, controlling the working state of the humidifying device according to the indoor environment humidity, the set humidity and the working mode.

It can be understood that, according to different operation modes of the air conditioner, the acquired indoor environment humidity and the set humidity can be determined, and the operation state of the humidifying device 104 can be controlled according to the determination condition, so as to reduce the heat loss of the heating element 201, improve the heating or humidifying efficiency, or reduce the air volume loss.

Specifically, when the air conditioner is in a heating mode, and the indoor environment humidity is greater than the set humidity, heating is required at this time, the humidifying device 104 needs the heating element 201 to work to provide heat for the air, and the baffle 204 is controlled to be adjusted to the second state, so that the baffle 204 is rotated to a position where the baffle 204 is shielded, more air flows pass through the heating element 201, and are heated by the heating element 201, and hot air is blown out from the air outlet 106.

When the air conditioner is in a refrigeration mode, the indoor environment humidity is less than the set humidity, humidification is needed at the moment, the humidification device 104 needs the heating element 201 to work to provide heat for the liquid of the water box assembly 202, the control baffle 204 is adjusted to the first state, the baffle 204 is rotated to the position where the airflow can be shielded by at least part of the heating element 201, the baffle 204 shields the airflow for the water box assembly 202, heat loss is reduced, and humidification efficiency is improved.

When the air conditioner is in a heating mode, the indoor environment humidity is less than the set humidity, heating and humidification are needed at the moment, the humidifying device 104 needs the heating element 201 to work to provide heat for the liquid of the water box assembly 202, meanwhile, the heating element 201 needs to work to provide heat for the air, the control baffle 204 is adjusted to be in an intermediate state, the baffle 204 is enabled to rotate to a position where part of the heating element 201 can shield the air flow, meanwhile, part of the heating element 201 can be in direct contact with the air flow to transfer heat, namely, part of the area of the heating element 201 is heated by the air, the effect of preheating the air is achieved, the temperature of the air reaches the preset requirement, the other part of the air can be humidified, and the requirement of the humidity is met.

Therefore, the control method of the air conditioner according to the embodiment of the present invention may determine the acquired indoor environment humidity and the set humidity according to different operation modes of the air conditioner, and control the operation state of the humidifying device 104 according to the determination condition so as to meet at least one of the humidifying requirement, the heating requirement, and the ventilation requirement.

Another embodiment of the present invention further provides a method for controlling an air conditioner, as shown in fig. 11, where fig. 11 is a schematic diagram of an embodiment of a flow step after step S1040 in fig. 10.

Step S1100, when the working mode is a refrigeration mode and the indoor environment humidity is less than the set humidity, the heating element is controlled to be opened, and the baffle is adjusted to be in the first state.

It will be appreciated that when the air conditioner enters the cooling mode, the sensed indoor ambient humidity is less than the set humidity indicating that humidification is required, i.e., the humidification device 104 requires the heating element 201 to operate to provide heat to the liquid in the water cartridge assembly 202. The control device controls the baffle 204 to be adjusted to the first state, so that the baffle 204 rotates to a position where at least part of the heating element 201 can shield the air flow, the baffle 204 shields the air flow for the water box assembly 202, heat loss is reduced, and humidification efficiency is improved.

For example, the damper 204 is adjusted to the position shown in fig. 7, i.e., the damper 204 is rotated to the first position, and at this time, the damper 204 is in the first position, and the damper 204 can completely block the airflow for the heating element 201. It should be noted that, here, the heating element 201 partially protrudes from the box body of the water box assembly 202, and is partially located in the box body of the water box assembly 202, so the baffle 204 only needs to be able to shield the airflow for the portion of the heating element 201 protruding from the box body.

It should be noted that, before controlling the humidifying device 104 to start, the liquid level in the water box assembly 202 may be detected, and if there is no liquid in the water box assembly 202 or the liquid level in the water box assembly 202 is low, the solenoid valve at the water inlet 302 may be controlled to open first, and when the water enters the water box assembly 202 through the filter of the water inlet 302 and the solenoid valve and reaches a predetermined water level, the liquid level switch 304 is activated to close the solenoid valve at the water inlet 302. The heating element 201 can be turned on simultaneously in the process of adding water to realize humidification, and the heating element 201 can be turned on again after the water is added to realize humidification.

Another embodiment of the present invention further provides a method for controlling an air conditioner, as shown in fig. 12, where fig. 12 is a schematic diagram of an embodiment of a flow step after step S1040 in fig. 10.

Step S1200, when the operation mode is the cooling mode and the indoor environment humidity is greater than or equal to the set humidity, controlling the heating element to be turned off, and adjusting the baffle to the second state.

It will be appreciated that when the air conditioner enters the cooling mode, the sensed indoor ambient humidity is greater than or equal to the set humidity, indicating that humidification is not required, i.e., the humidification device 104 does not require the heating element 201 to operate to provide heat to the liquid in the water box assembly 202. In this case, the main purpose of the air conditioner is to improve the cooling efficiency, so that the air volume loss can be reduced by adjusting the position of the baffle 204 to reduce the obstruction of the airflow by the baffle 204.

For example, the damper 204 is in the state shown in fig. 8, that is, the damper 204 is rotated to the second position, and at this time, the damper 204 is in the second state, and the damper 204 does not block the air flow directly blowing to the heating element 201. It should be noted that, here, the heating element 201 partially protrudes from the box body of the water box assembly 202, and is partially located in the box body of the water box assembly 202, so the baffle 204 only needs to be staggered with the portion of the heating element 201 protruding from the box body.

For another example, the damper 204 is adjusted to be in the state shown in fig. 9, that is, the damper 204 is rotated to a position between the first position and the second position, and at this time, the damper 204 is in the intermediate state, and the damper 204 can block part of the air flow directly blowing to the heating element 201. In the heating and humidifying mode, the baffle 204 rotates to a position between the first position and the second position, so that the heating element 201 can be partitioned, a part of the area is heated by air to meet the function of preheating the air, the temperature of the air reaches a preset requirement, and the other part of the area can be humidified to meet the requirement of humidity.

Another embodiment of the present invention further provides a method for controlling an air conditioner, as shown in fig. 13, where fig. 13 is a schematic diagram of an embodiment of a flow step after step S1040 in fig. 10.

Step 1300, when the working mode is the heating mode and the difference between the set humidity and the indoor environment humidity is greater than or equal to a first preset value, controlling the baffle to be adjusted to a first state.

It can be understood that the air conditioner absorbs and transfers the heat energy of the outdoor air to the indoor when heating, but the air conditioner has a poor heating effect if the outdoor air temperature is too low. The design of electric auxiliary heating is actually to improve the heating effect of the air conditioner in cold weather, the temperature of the air conditioner with electric auxiliary heating rises faster, and the temperature of the air conditioner without electric auxiliary heating rises slightly slower.

It should be noted that the operation mode of the air conditioner mentioned in this embodiment is a heating mode, and the default is that the refrigerant heat exchange and electric auxiliary heating functions are already turned on, that is, when the operation mode is the heating mode, the default is that the heating element 201 is already turned on to operate. Of course, for an air conditioner without separately providing the heating element 201 to achieve electric auxiliary heating, it is still necessary to control the heating element 201 in the humidifying device 104 to be turned on.

It can be understood that, when the air conditioner enters the heating mode, the heating element 201 can be controlled to work first, the adjusting baffle 204 is in the second state, so that the heating element 201 realizes the electric auxiliary heating function, when the indoor environment temperature reaches the set temperature, the indoor environment humidity is detected, when the difference obtained by subtracting the indoor environment humidity from the set humidity is greater than the first preset value, the adjusting baffle 204 is in the state shown in fig. 7, that is, the baffle 204 rotates to the first position, at this moment, the baffle 204 is in the first state, the baffle 204 can completely shield the air flow for the heating element 201, so that the heat of the heating element 201 is more effectively provided for the liquid of the water box assembly 202, and the humidifying efficiency is improved.

It should be noted that, when the air conditioner enters the heating mode, and when it is detected that the difference between the set humidity and the indoor ambient humidity is greater than the first preset value, the baffle 204 may also be controlled to be in the first state first, so as to improve the humidification efficiency, and meet the humidification requirement first, and then the baffle 204 is controlled to be in the second state, so that the heating element 201 realizes the electric auxiliary heating function, and meets the heating requirement.

It should be noted that when the air conditioner enters the heating mode, the heating element 201 performs the electric auxiliary heating function, but does not perform the humidifying function, the solenoid valve at the water outlet 303 is controlled to open, so as to discharge the liquid in the water box assembly 202 first, thereby avoiding the reduction of the air heating efficiency. Certainly, when the air conditioner is turned off every time, the electromagnetic valve at the water outlet 303 is controlled to be opened, liquid in the water box assembly 202 is discharged into the water pan 107 and then discharged through the water outlet of the whole air conditioner, and therefore bacterial breeding caused by long-time water storage is prevented.

It should be noted that, when the air conditioner enters the heating mode, the indoor ambient humidity is detected, and when a difference obtained by subtracting the indoor ambient humidity from the set humidity is greater than a first preset value, if there is no liquid in the water box assembly 202 or the liquid level of the liquid in the water box assembly 202 is low, the electromagnetic valve at the water inlet 302 may be first controlled to be opened, and when the water enters the water box assembly 202 through the filter of the water inlet 302 and the electromagnetic valve and reaches a predetermined water level, the liquid level switch 304 operates to close the electromagnetic valve at the water inlet 302. The heating element 201 can be turned on simultaneously in the process of adding water to realize humidification, and the heating element 201 can be turned on again after the water is added to realize humidification.

It should be noted that the first preset value may be set as needed, and the embodiment does not specifically limit the first preset value.

Another embodiment of the present invention further provides a control method of an air conditioner, as shown in fig. 14, fig. 14 is a schematic diagram of an embodiment of a flow step after step S1040 in fig. 10. The baffle 204 of the air conditioner can be adjusted to a third state, when the baffle 204 is in the third state, the baffle 204 can shield airflow for part of the heating element 201, and when the baffle 204 is in the third state along the air outlet direction of the air duct, the area of the heating element 201 shielded by the baffle 204 is smaller than the area of the heating element 201 shielded by the baffle 204 when the baffle 204 is in the first state. That is, when the baffle 204 is switched from the first state to the third state along the air outlet direction of the air duct, the area of the baffle 204 shielding the heating element 201 is reduced.

And step S1400, when the working mode is the heating mode and the difference between the set humidity and the indoor environment humidity is greater than zero and smaller than a first preset value, controlling the baffle to be adjusted to a third state.

It can be understood that when the air conditioner enters the heating mode, the difference obtained by subtracting the detected indoor environment humidity value from the set humidity value is greater than zero, and the difference is smaller than the first preset value, which indicates that humidification is required in the environment, but the humidification requirement is not particularly large, and then a part of the heating element 201 can be directly contacted with the air flow to take the heating effect into consideration. Therefore, the third state is an intermediate state between the first state and the second state, the baffle 204 is controlled to be adjusted to the third state along the air outlet direction of the air duct, the area of the baffle 204 shielding the heating element 201 is small, the heating element 201 is partitioned, so that air heating is performed in a part of the area of the heating element 201, the effect of preheating air is met, the temperature of the air reaches a preset requirement, and the other part of the air can be humidified, so that the requirement of humidity is met.

In combination with step S1300 and step S1400, it can also be understood that the first preset value is a critical value for determining a difference between the set humidity value and the indoor environment humidity value, and when the difference between the set humidity and the indoor environment humidity is greater than the first preset value, it indicates that the humidification requirement is large, and it is necessary for the heating element 201 to transfer the generated heat to the liquid in the water box assembly 202 as much as possible; when the difference between the set humidity and the indoor environment humidity is greater than zero and smaller than a first preset value, the humidification requirement is indicated, but the difference is not particularly large, a part of heat generated by the heating element 201 can be used for heating liquid in the water heating box assembly 202 to meet the humidification requirement, and a part of heat is used for heating air to improve the heating effect.

Another embodiment of the present invention further provides a method for controlling an air conditioner, as shown in fig. 15, where fig. 15 is a schematic diagram of an embodiment of a flow step after step S1040 in fig. 10. The baffle 204 of the air conditioner can be adjusted to a fourth state, when the baffle 204 is in the fourth state, the baffle 204 can shield the airflow for part of the heating element 201, and along the air outlet direction of the air duct, the area of the heating element 201 shielded by the baffle 204 in the fourth state is smaller than the area of the heating element 201 shielded by the baffle 204 in the third state. That is, when the baffle 204 is switched from the third state to the fourth state along the air outlet direction of the air duct, the area of the baffle 204 shielding the heating element 201 is reduced.

And S1500, when the working mode is a heating mode and the difference value between the indoor environment humidity and the set humidity is larger than zero and smaller than a second preset value, controlling the baffle to be adjusted to a fourth state.

It can be understood that, when the air conditioner enters the heating mode, the difference obtained by subtracting the set humidity value from the detected indoor environment humidity value is greater than zero, and the difference is smaller than the second preset value, which indicates that in the environment, the indoor environment humidity can reach the set humidity, but the difference between the detected indoor environment humidity and the set humidity is not great, and the humidifying device 104 needs to continue to operate to maintain the indoor environment humidity within the set range, at this time, a large area of the heating element 201 can be used for heating air, and a small area of the heating element 201 can be used for humidifying air.

Therefore, the baffle 204 is controlled to be adjusted to a fourth state, the fourth state is an intermediate state between the first state and the second state, along the air outlet direction of the air duct, the area of the heating element 201 shielded by the baffle 204 is small, the heating element 201 is partitioned, so that air heating is performed in a part of the area of the heating element 201, the effect of preheating air is met, the temperature of the air reaches a preset requirement, and the other part of the air can be humidified, so that the requirement of humidity is met. Moreover, when the baffle 204 is in the fourth state, the area of the heating element 201 shielded by the baffle 204 is smaller than that when the baffle 204 is in the third state, the area of the heating element 201 shielded by the baffle 204 is smaller than that when the baffle 204 is in the fourth state. For example, when the shutter 204 is in the third state, the shutter 204 blocks the area below 3/4 of the heating element 201, and when the shutter 204 is in the fourth state, the shutter 204 blocks the area below 1/2 of the heating element 201.

It should be noted that the second preset value can be set as needed, and the embodiment does not specifically limit the second preset value.

Another embodiment of the present invention further provides a method for controlling an air conditioner, as shown in fig. 16, where fig. 16 is a schematic diagram of an embodiment of a flow step after step S1040 in fig. 10.

Step S1600, when the working mode is the heating mode and the difference between the indoor ambient humidity and the set humidity is greater than the second preset value, controlling the baffle to adjust to the second state.

It can be understood that, when the air conditioner enters the heating mode, the difference obtained by subtracting the set humidity value from the detected indoor environment humidity value is greater than zero, and the second preset value of the difference indicates that in the environment, the indoor environment humidity can reach the set humidity, and the difference between the indoor environment humidity and the set humidity is large, so that the humidification can be suspended, and the indoor environment humidity can be maintained within the set range within a certain time. The baffle 204 is controlled to be adjusted to the second state, and the baffle 204 does not shield the airflow directly blowing to the heating element 201, so that the heating element 201 can completely heat the air, the effect of preheating the air is met, and the temperature of the air can reach the preset requirement. Of course, if the temperature has reached the predetermined requirement, the control damper 204 is adjusted to the second state, and the heating element 201 does not work, so that the wind resistance and the air loss can be reduced.

It should be noted that, the control damper 204 is adjusted to the second state, and humidification is not required, and the electromagnetic valve at the drain port 303 is controlled to open, so as to drain the liquid in the water box assembly 202 first, thereby avoiding reduction of the efficiency of heating the air.

It can be understood that when the air conditioner is turned off, the control baffle 204 is adjusted to the minimum windward angle, so that the air conditioner has a better air outlet effect when turned on next time. And the electromagnetic valve at the water outlet 303 is opened to drain the water box assembly 202, so that the bacteria caused by long-time water storage are prevented from breeding.
