Optionally, the adjusting assembly 30 is configured to adjust an air outlet state of at least one of the humidification regions. Specifically, the adjusting assembly 30 includes a driving member 32 and a switching baffle 31, the driving member 32 is connected to the switching baffle 31, and the driving member 32 is configured to drive the switching baffle 31 to move between a first position and a second position. When the switching baffle 31 is at the first position, the humidifying port 23 on the humidifying area can be opened, and when the switching baffle 31 is at the second position, the humidifying port 23 on the humidifying area can be directly blocked or the communication between the humidifying port 23 and the humidifier 21 can be blocked; in some embodiments, one switching baffle 31 is disposed on each humidifying opening 23, the switching baffle 31 is movably disposed on the humidifying pipeline 22, and when moving to a position corresponding to the humidifying opening 23, the switching baffle 31 blocks the humidifying opening 23, and when moving to a position away from the humidifying opening 23, the switching baffle opens the humidifying opening 23, so as to adjust the air outlet state of the humidifying area; in other embodiments, the switching damper 31 can be movably disposed between two adjacent humidification regions in the humidification duct 22, for example, the switching damper 31 can be rotatably disposed between two adjacent humidification regions, wherein the humidification port 23 is communicated with the heat exchange air duct 15, when the switching damper 31 is rotated to one position, the switching damper 31 blocks the two adjacent humidification regions from communicating, and when the switching damper 31 is rotated to another position, the two adjacent switching dampers 31 communicate. The switching damper 31 may be located in the humidification duct 22 or between the humidification duct 22 and the scroll casing 13.

Optionally, the driving member 32 is a motor, and the motor is connected with the controller.

Or, the humidification duct 22 is disposed between the volute casing 13 and the housing 10, a connection air duct is formed between the through hole on the volute casing 13 and the humidification port on the humidification duct 22, the connection air duct communicates the humidification duct 22 with the heat exchange air duct 15, optionally, the switching baffle 31 is movably disposed in the connection air duct, and the air outlet state of the humidification port 23 is changed by opening or closing the connection air duct.

Alternatively, referring to fig. 5 and 6, the switching damper 31 may also adjust the air outlet state of the humidification region by plugging or conducting the humidification duct 22.

In some embodiments, the adjustment assembly 30 includes a switching damper 31, and the switching damper 31 is movably disposed between two adjacent humidification regions in the humidification duct 22 to adjust the air flow through the humidification regions in the humidification duct 22. The humidified air enters the humidification duct 22 from the air inlet end of the humidification duct 22, at least one humidification region is arranged between the switching flap 31 and the air inlet end, and at least one humidification region is also arranged on the side of the switching flap 31 far away from the air inlet end, so that the air outlet state of the humidification region on the side of the switching flap 31 far away from the air inlet end is switched between the first state and the second state based on the adjustment of the switching flap 31.

Specifically, the switching damper 31 has a first position and a second position, and the air volume of the humidification duct 22 when the switching damper 31 moves to the first position is larger than the air volume of the humidification duct 22 when the switching damper 31 moves to the second position. That is, when the switching flap 31 moves to the first position, the air outlet state of the humidification region is switched to the first state, and when the switching flap 31 moves to the second position, the air outlet state of the humidification region is switched to the second state. The connection manner of the switching baffle 31 and the humidification duct 22 includes one of movement and rotation, for example, one end of the switching baffle 31 is rotatably connected with the inner wall of the humidification duct 22, and the other end of the switching baffle 31 rotates around the inner wall of the humidification duct 22; and the movement is a radial movement of the switching damper 31 along the humidification duct 22.

In some embodiments, the first position is a position where the switching damper 31 is parallel to the air flow direction in the humidification duct 22; the second position is a position where the switching damper 31 is perpendicular to the air flow direction in the humidification duct 22. When the switching baffle 31 rotates to the first position, the switching baffle 31 makes the humidification duct 22 be conducted, and at this time, the humidification regions (humidification ports 23) can be normally discharged, that is, the humidification regions are in the first state, and if the humidification ports 23 normally discharge air, the humidification duct 22 outputs humidified air to each humidification region, and then the humidified air is conveyed into the heat exchange air duct 15 by each humidification region.

When the switching damper 31 is rotated to the second position, the switching damper 31 blocks a part of the flow section of the humidification duct 22, so that the humidification duct 22 can only output humidified air to a part of the humidification region, and a part of the humidification region on the blocked flow section has no humidified air or only a small amount of humidified air, so that a part of the humidification region (the humidification port 23) cannot be normally exhausted, and at this time, the part of the humidification region is in the second state.

In the embodiment that the switching flap 31 closes or opens the humidification duct 22 to adjust the air outlet state of the humidification region, since the humidification duct 22 is directly closed, air cannot be delivered to other humidification regions far from the air inlet end of the humidification duct 22 relative to the switching flap 31, and therefore in this embodiment, when the switching flap 31 rotates to the second position, the humidification region far from the air inlet end on the humidification duct 22 is first adjusted to the second state. Based on the fact that the humidified air easily sinks, even if uniform humidification is achieved by distributing the humidification area along the length direction of the air outlet 12, when humidification time reaches a certain time, the humidity at the bottom of the room is higher than that at the top, so that in order to further improve the humidification effect of the cabinet air conditioner, the embodiment of the invention provides a further optimized embodiment based on the embodiment:

for example, when the indoor unit 100 is a cabinet, the air outlet is located between the top and the bottom of the cabinet 10. The lower part of the cabinet is more efficient in humidifying and has higher humidity due to the sinking of air, so that the lower part of the indoor unit 100 can be reduced in humidifying amount by turning off the lower humidifying region or reducing the air flow rate based on the humidity change during the humidifying process. Therefore, the humidification device 20 of the embodiment is reasonably arranged to adjust the humidity more uniformly, so that the humidification effect is better.

Specifically, the humidifying pipe 22 extends from the top of the housing 10 to the bottom of the housing 10, and one end of the humidifying pipe 22 close to the top is the air inlet end, so that, in the humidifying process, the humidifying area located at the lower part of the housing 10 first by the adjusting component 30 is in the second state, for example, the humidifying port 23 corresponding to the humidifying area is adjusted to be closed or the air flow is reduced, so as to avoid the humidity of the lower part from increasing continuously, while the humidifying area close to the air inlet end is kept in the first state, for example, the humidifying port 23 close to the air inlet end is opened, so as to humidify the air humidity of the upper part of the housing 10 continuously, so that the upper part and the lower part are kept balanced, and further, the humidity of the upper layer and the lower layer in the room is kept balanced, and the humidity difference is reduced.

The humidifier 21 may be disposed at the top of the housing 10, and the humidifying conduit 22 extends from the humidifier 21 in a direction away from the humidifier 21, so that the humidifying conduit 22 extends from the top to the bottom of the housing 10. The air humidified by the humidifier 21 is discharged from the top to the bottom of the housing 10 to the heat exchange air duct 15, so that when the adjustment assembly 30 adjusts the humidification port 23 to the second state, the adjustment is started from the bottom of the housing 10, the humidity of the bottom is controlled first, and the humidity of the top sinks to the bottom along with time, so that the situation that the humidity of the bottom is low due to the fact that the humidification is stopped does not occur, and relatively speaking, the humidity difference between the top and the bottom is reduced.

Or, in an alternative embodiment, the humidifier 21 is disposed at the bottom of the casing 10, a gas transmission pipe 24 is disposed on the humidifier 21, one end of the gas transmission pipe 24 away from the humidifier 21 is communicated with one end of the humidification pipe 22 close to the top of the casing 10, and the air humidified by the humidifier 21 is transmitted to the top of the casing 10 through the gas transmission pipe 24, and then transmitted into the humidification pipe 22 from the top of the casing 10, and is discharged to the heat exchange air duct 15 through the humidification pipe 22. In this way, the air humidified by the humidifier 21 is discharged from the top of the casing 10 to the bottom of the casing 10 toward the heat exchange air duct 15.

In this embodiment, the humidifier 21 is disposed at the bottom of the casing 10, so that the top of the indoor unit 100 is prevented from being too heavy, and the humidifier 21 is disposed at the bottom, so that it is convenient to replace and maintain, and is convenient to connect with the water tank 40.

This embodiment is through setting up adjustment subassembly 30 adjusts each the state in humidification region, when local humidity is higher, switch the second state (if close) with the air-out state in the humidification region that the higher position of humidity corresponds, and keep the air-out state in the humidification region that the lower position of humidity corresponds to be the first state (if open, normal air-out), can further adjust indoor humidification balance, reach more humidification effect.

In an optional embodiment, when the indoor unit 100 is a cabinet, and the air outlet 12 is located at the position where the indoor unit 100 is a cabinet, the air outlet 12 is located between the top and the bottom of the indoor unit 100 along the humidifying area, the humidifying area is distributed along the top of the indoor unit 100 toward the bottom of the indoor unit 100, and each humidifying area can be communicated with the air outlet 12.

Specifically, the hardware environment frame related to the control method of the indoor unit may include a control terminal, for example, the control terminal is a mobile terminal, an air conditioner, or an indoor unit with an independent processor, and the control terminal is configured to control the indoor unit to implement the control method in each of the following embodiments.

As one implementation manner, the control terminal includes: a processor 101, e.g. a CPU, a memory 102, a communication bus 103. Wherein a communication bus 103 is used for enabling the connection communication between these components. The processor 102 is used to invoke an application program to perform a control function.

and controlling the adjusting assembly to adjust the air outlet state of the humidifying area of the indoor unit so as to enable the air outlet state of at least one humidifying area to be a first state, wherein the air outlet state comprises a first state and a second state, and the air outlet amount of the humidifying area in the first state is larger than that in the second state.

Although the air conditioner based on the example has the heat exchange function and the humidification function, in the conventional design, the humidification air outlet and the heat exchange air outlet are independently and separately designed, and the humidification air outlet is generally arranged below the heat exchange air outlet, and the humidification air easily sinks, so that the humidification is not uniform, the local humidity is high, and the humidification effect is poor. The invention provides various embodiments of the control method of the indoor unit, so that when the indoor unit starts humidifying, the air outlet state of each humidifying port of the humidifying device is reasonably adjusted by controlling the adjusting component, the aim of uniformly humidifying the indoor is achieved, and the condition of overhigh target local humidity occurs.

The first embodiment:

step S10, controlling the starting of the humidifying device of the indoor unit;

step S20, controlling the adjusting assembly to adjust the air outlet state of the humidification region of the indoor unit, so that the air outlet state of at least one humidification region is in a first state.

The execution terminal of this embodiment is a control terminal, and the control terminal may be a mobile terminal, an air conditioner, or an indoor unit with an independent processor, and the like. The control terminal is connected with the humidifying device and the adjusting component of the indoor unit, and in the operation process, the humidifying device is controlled to be started based on a humidifying instruction, and the adjusting component is controlled to adjust the air outlet state of each humidifying area.

Referring to fig. 1, 2 and 5 in combination, the indoor unit 100 includes:

It can be understood that, when the humidifying area is in the first state, the humidifying area is opened, and air can be normally discharged. When the humidification region is in the second state, the humidification region correspondence can be closed, if the air cannot be exhausted, or the humidification region correspondence can also be partially closed, if the air output is less than the air output when the normal air is exhausted.

In this embodiment, when receiving a humidification instruction, the control terminal controls the humidification device 20 of the indoor unit 100 to start, and when the humidification device 20 starts, the control terminal starts to humidify air, and conveys the humidified air to the heat exchange air duct 15 of the indoor unit 100 through the humidification region, mixes the humidified air with the heat-exchanged air in the heat exchange air duct 15, and then discharges the air from the air outlet 12 to the room. Based on the humidification region is direct will pass through the air transport of humidification to the heat transfer wind channel for the air after the heat transfer is in with the air after the humidification the heat transfer wind channel 15 internal mixing back row to indoor again, and is a plurality of the humidification region can be with the air after the humidification carry through different positions in the heat transfer wind channel 15, the air after the evenly distributed humidification. The humidification instruction may be triggered manually by a user or automatically by the indoor unit 100, and if the indoor humidity is less than the first preset threshold, the control terminal receives the humidification instruction and controls the humidification device 20 of the indoor unit 100 to start humidification.

In this embodiment, the adjustment component 30 adjusts the air outlet state of the humidification region, so as to further improve the uniformity of the distribution of the humidified air. Specifically, when the humidifying area is in the first state, the humidifying area is communicated with the heat exchange air duct, that is, the humidifying area can exhaust air; when the humidifying area is in the second state, the humidifying area can be not communicated or partially communicated with the heat exchange air duct, namely the humidifying area does not output air or the air output is small. In this way, the adjustment component 30 adjusts the state of the humidification region, so as to adjust the humidification of each position, and further achieve uniform humidification.

In this embodiment, the indoor unit 100 performs humidification based on the humidification device 20, and the humidification device 20 is provided with at least two humidification areas that can be communicated with the heat exchange air duct, and the humidification areas are separately arranged based on the humidification areas, so that the humidified air can be prevented from being discharged from one position; and adjust through setting up adjustment assembly 20 the air-out state in humidification region, so, can adjust the humidification volume of each position through the air-out state in the humidification region of adjustment difference for each position humidification is balanced, so, can avoid local humidity too high, improves the humidification effect.

Optionally, in this embodiment, after the humidification device 20 is started, the manner in which the control terminal controls the adjustment assembly 30 to adjust the air outlet state of the humidification region of the indoor unit 100 includes, but is not limited to, the following two embodiments:

in some embodiments, referring to fig. 10, the step of controlling the adjusting assembly to adjust the air outlet state of the humidification regions of the indoor unit so that the air outlet state of at least one humidification region is the first state includes:

step S21, acquiring the indoor humidity value of the indoor unit;

step S22, adjusting the air outlet state of the humidification regions according to the humidity value, so that at least one humidification region is in a first state.

In this embodiment, a humidity sensor is disposed at the air return opening of the indoor unit or in the environment where the indoor unit is located, and is configured to detect an indoor humidity value, and further adjust the air outlet state of each of the humidification openings according to the humidity value.

In some embodiments, please refer to fig. 5 in combination, the adjusting assembly 30 includes a switching baffle 31, and each of the humidification regions is provided with one switching baffle 31 to adjust the air outlet state of the humidification region. When the indoor humidity value is detected to be high, the second state of switching the humidification regions is controlled, so that the air output of part of the humidification regions is reduced, and the humidity of the regions corresponding to the humidification regions is further reduced.

In some embodiments, a plurality of humidity sensors are arranged in the chamber, the plurality of humidity sensors are distributed at different positions in the chamber, a target humidification area is determined by acquiring the humidity sensor with a lower humidity value, the target humidification area is controlled to be switched to the first state, and other humidification areas are kept in the second state, so that the humidity of the position with higher humidity can be reduced, and the position with lower humidity is continuously humidified, so that the humidity of each position in the chamber is kept uniform. The target humidification region is adjusted to be opened, so that air in the target humidification region is normally exhausted, the position corresponding to the target humidification region can be normally humidified, and other humidification regions except the target humidification region are closed or the air outlet amount is small, so that the humidification amount in the positions corresponding to the other humidification regions is reduced, the humidity difference between the position corresponding to the target humidification region and the positions corresponding to the other humidification regions is reduced, and the humidification at each position is balanced.

Or, in some embodiments, based on the principle that the humidified air sinks, a humidity sensor is arranged at an air inlet of the indoor unit, and when a large humidity value is detected, the humidification area close to the air inlet is adjusted to be kept in the second state, and other humidification areas are adjusted to be in the first state, so that the indoor humidity is kept uniform.

This embodiment adjusts according to the humidity value that real-time or regularly detected the air-out state in humidification region can be when making the humidity of environment in place reach the humidity demand, keep humidity balance, improve the humidification degree of consistency.

In other embodiments, referring to fig. 11, the humidifying pipeline of the humidifying device is provided with at least two humidifying regions along an extending direction thereof, and the step of controlling the adjusting assembly to adjust the air outlet state of the humidifying region of the indoor unit so that the air outlet state of at least one of the humidifying regions is in the first state includes:

step S23, sequentially adjusting the humidification regions to the first state along the extending direction of the humidification duct;

in step S24, after a second preset time interval, each humidification area is adjusted to the second state in a direction opposite to the extending direction.

It is understood that the steps S23, S24 described above are repeatedly performed every preset time period.

In some embodiments, referring to fig. 5 and fig. 6 in combination, the adjusting group 30 is disposed in the humidifying pipe 22, and specifically adjusts the air outlet state of the humidifying area by adjusting the air flow rate of the humidifying pipe 22. The humidifying area between the adjusting assembly 30 and the air inlet end of the humidifying pipeline 22 is not provided with the adjusting assembly 30, so that the humidifying area is always in the first state, such as the humidifying area is always opened. Thus, after the humidifying device 20 is started, at least one of the humidifying areas is always kept in the first state, if at least one of the humidifying areas is always kept open, the adjustment of each pair of humidifying areas to the second state means that the humidifying area correspondingly adjusted by each adjusting component is adjusted to the second state, if the humidifying opening 23 on the corresponding humidifying area is closed.

In this embodiment, based on the humidification device 20 is provided with a plurality of humidification regions, and the air-out state of the humidification regions is adjusted by the adjustment component 30, in this way, after the humidification device 20 is started, the humidification regions are sequentially controlled to be adjusted to the first state, and then the humidification regions are controlled to be adjusted to the second state, so as to achieve the purpose of air sweeping and humidification, and achieve uniform humidification of the indoor space.

It can be understood that at least one humidification port is disposed on the humidification region, and the humidification region realizes air outlet through the humidification 23, for example, the humidification port 23 is communicated with the heat exchange air duct 15, or the humidification port 23 is communicated with the through hole 16 on the scroll 13.

In an optional embodiment, in order to reduce the setting of the adjustment assembly 30, in this embodiment, at least one humidification port is correspondingly arranged in each humidification region, and in the humidification process, the air outlet states of the plurality of humidification ports are correspondingly controlled by controlling the first state of each humidification region, so that the setting of the adjustment assembly is reduced.

In the following embodiments, specific implementation manners of the adjusting assembly 30 adjusting the air outlet state of the humidification region of the indoor unit 100 when the humidification duct 22 of the humidification device 20 is provided with two humidification regions along the extending direction thereof are described: if the first humidification region and the second humidification region are sequentially arranged along the air flowing direction of the humidification duct 22, after the humidification device 20 is started, the first humidification region is controlled to be adjusted to the first state, for example, a humidification port corresponding to the first humidification region is opened, so that the first humidification region is humidified first; and then controlling the second humidifying area to be adjusted to the first state, and if a humidifying port corresponding to the second humidifying area is opened, humidifying the first humidifying area and the second humidifying area simultaneously. After a second preset time interval, the second humidification area is controlled to be adjusted to the second state, if the humidification port corresponding to the second humidification area is closed, the humidification port corresponding to the second humidification area stops humidifying, and then the first humidification area is controlled to be adjusted to the second state, if the humidification port 23 corresponding to the first humidification area is closed, the humidification port corresponding to the second humidification area stops humidifying. The air outlet states of all the humidification areas are circularly controlled in sequence, so that the indoor humidity is uniform.

Alternatively, in an on-hook embodiment, the air flow direction of the humidification duct 22 may be horizontal from left to right, or horizontal from right to left. In the cabinet embodiment, the air flow direction of the humidifying conduit 22 is a vertical direction from top to bottom.

When the indoor unit is a cabinet type indoor unit, the humidification duct 22 extends along the axial direction of the scroll casing 13, so that the humidification areas on the humidification duct 22 are distributed along the up-down direction of the indoor unit 100. This embodiment is followed humidification pipeline 22's extending direction is in proper order with each the humidification region adjusts to first state, sweeps wind humidification from top to bottom, so, can be so that the even humidification of the air of indoor upper and middle and lower floor, improve indoor whole comfort level.

In some embodiments, after the air outlet state of each humidification region is adjusted, the air outlet state of the next humidification region is adjusted after the preset duration, so that the adjustment assembly 30 for adjusting the air outlet state of the humidification region is prevented from being switched too frequently, and the adjustment assembly 30 is prevented from being damaged.

Optionally, after each humidification area is adjusted to the second state, and after a third preset time interval, the step of sequentially adjusting each humidification area to the first state along the extending direction of the humidification duct 22 is returned to be executed. The second preset time interval is smaller than the third preset time interval so as to convey more humidified air to the upper part of the room, and when the humidified air is prevented from sinking, the humidity of the air at the upper part of the room is lower.

Second embodiment

Based on the first embodiment, the present embodiment is specifically applied to a cabinet air conditioner, the humidification duct 22 of the humidification apparatus 20 extends along the length direction of the air outlet 12, so that the humidification areas on the humidification duct 22 are uniformly distributed at the corresponding positions of the air outlet 12, specifically, the air flowing direction of the humidification duct 22 goes from the top of the indoor unit 100 to the bottom of the indoor unit, the adjustment assembly 30 includes a switching baffle 31, and the switching baffle 31 is movably disposed between two adjacent humidification areas in the humidification duct. Referring to fig. 12, the step of adjusting the air outlet state of the humidification regions according to the humidity value to make at least one humidification region in the first state includes:

step S221, when the humidity value is smaller than a first preset threshold, adjusting all the humidification regions to the first state.

In step S222, after a first preset time interval, if the humidity value is greater than or equal to the first preset threshold, a part of the humidification region is adjusted to the second state.

In this embodiment, the air flowing direction of the humidification duct 22 is from the top of the indoor unit 100 to the bottom of the indoor unit 100, and the extension direction of the humidification duct 22 is the same as the air flowing direction, so that the humidification regions are spaced from the top to the bottom of the indoor unit 100.

The problem that the humidity of the lower layer in the room is high and the humidity of the middle layer or the upper layer in the room is low is easily caused by the air after humidification sinking. The embodiment combines the structural arrangement of the humidifying pipeline 22, controls the humidifying amount of different positions by reasonably selecting the humidifying or all humidifying modes, and enables the positions to be uniformly humidified.

Specifically, a critical value is preset, for example, a first preset threshold value, when the indoor humidity value is lower than the first preset threshold value, it is determined that the indoor overall humidity is low, and at this time, the humidification regions need to be fully exhausted, that is, all the humidification regions are in the first state, so as to uniformly and rapidly humidify the indoor space. When the indoor humidity value is higher than the first preset threshold value, the humidity of the lower layer (lower than 1 m) is relatively high compared with that of the middle layer and that of the upper layer due to air sinking, and the indoor humidity of the lower layer is judged to be high, while the humidity of the middle layer or the upper layer still does not meet the requirement of the target set humidity. If all the humidification regions are fully exhausted, the humidity of the lower layer in the room is easy to be higher and higher, and the uncomfortable condition of high local temperature is easy to occur, therefore, at this time, part of the humidification regions are selected to exhaust air, especially the humidification regions in the middle and upper parts of the indoor unit, and the humidification regions in the lower part of the indoor unit 100 do not exhaust air, if the humidification regions are in the second state, the humidification air exhausted to the lower part in the room is reduced, and the discharge of the humidification air in the upper part in the room is kept, so that the humidity difference of each position in the room is reduced, and the purpose of uniform humidification is achieved.

Optionally, after the humidifying device 20 is turned on, if it is detected that the humidity value is greater than or equal to the first preset threshold, a part of the humidifying area is adjusted to the first state, and the humidifying area is a humidifying area far away from the bottom of the indoor unit 100. If all the humidification areas are adjusted to the first state, all the humidification areas convey humidified air to the heat exchange air duct 15 of the indoor unit 100, after a first preset time interval, the indoor humidity value is detected again, and if the humidity value is greater than or equal to the first preset threshold value, part of the humidification areas are adjusted to the second state to reduce the humidification amount. The partial humidification area in the second state is a humidification area relatively located at the bottom of the indoor unit 100, and the other humidification areas are kept in the first state for continuous humidification.

This implementation makes the humidification effect of indoor set is better.

The third embodiment:

the present embodiment is specifically applied to a cabinet air conditioner, and a further refined humidification scheme is provided based on the second embodiment, so that the indoor humidification is more uniform, and the humidification effect of the indoor unit 100 is better. Specifically, in this embodiment, the step of providing at least two humidification regions in the humidification duct 22 of the humidification device 20, where the humidification regions are distributed from the top of the indoor unit 100 to the bottom of the indoor unit 100, referring to fig. 13, the step of adjusting the air-out state of the humidification regions according to the humidity value to make at least one humidification region in the first state includes:

Step S223 is to adjust at least one humidification region near the top of the indoor unit to the first state when the humidity value is greater than or equal to the first preset threshold and smaller than a second preset threshold, where the first preset threshold is smaller than the second preset threshold.

That is, in this embodiment, at least two critical values are preset, such as a first preset threshold and a second preset threshold, where the first preset threshold is smaller than the second threshold. That is, when the indoor humidity value is lower than the first preset threshold, it is determined that the indoor overall humidity is low, and at this time, the humidification regions are required to be fully exhausted, and if all the humidification regions are in the first state, the indoor humidification is performed uniformly and rapidly. When the indoor humidity value is higher than the first preset threshold value and lower than the second preset threshold value, the humidity of the lower layer is relatively higher than that of the middle layer and that of the upper layer due to air sinking, and the indoor humidity of the lower layer is judged to be high, while the humidity of the middle layer or the upper layer still does not meet the requirement of the target set humidity. If it is whole at this moment the regional full air-out of humidification leads to indoor lower floor humidity more and more high easily, appears the higher uncomfortable condition of local temperature easily, and if close humidification device this moment, then probably appear upper portion air drier, user's face wait position uncomfortable to influence user experience. Therefore, at this time, part of the humidified area is selected to output air, especially the humidified openings in the middle and upper parts of the indoor unit, and the humidified area in the lower part of the indoor unit does not output air, so that if the humidified area is in the second state, the humidified air discharged to the lower part of the indoor unit is reduced, and the discharge of the humidified air in the upper part of the indoor unit is maintained, so that the humidity difference of each position in the indoor unit is reduced, and the aim of uniformly humidifying is fulfilled. When the indoor humidity value is higher than the second preset threshold value, the humidity of the indoor lower layer is judged to be high, the humidity of the indoor middle layer is judged to be high, the humidity of the indoor upper layer still does not meet the requirement of the target set humidity, at the moment, only the humidifying area on the upper portion of the indoor unit is enabled to exhaust air, and the humidifying areas on the lower portion and the middle portion of the indoor unit do not exhaust air, so that the humidity difference value between the positions is reduced.

Based on this, at least two humidification areas are arranged in the humidification pipeline of the humidification device of this embodiment, when the humidity value is greater than or equal to the first preset threshold and smaller than the second preset threshold, at least one humidification area near the top of the indoor unit 100 is adjusted to the first state, and the other humidification areas are kept in the second state, that is, the humidification area near the top of the indoor unit 100 is blown out, and the other humidification areas are not blown out or are blown out with a small amount, so that the bottom humidity is prevented from being too high. In this manner, the humidity difference between the respective positions can be reduced.

It is understood that the number of humidification regions near the top of the indoor unit 100 is determined based on the number of humidification region divisions, and the more the humidification regions are divided, the higher the accuracy of humidification control.

In this embodiment, some embodiments are described, for example, three humidification regions are disposed in the humidification duct, and the three humidification regions are respectively a first humidification region, a second humidification region and a third humidification region which are sequentially disposed from the top of the indoor unit to the bottom of the indoor unit at intervals, where the first humidification region corresponds to humidifying air at the upper portion of the indoor unit, the second humidification region corresponds to humidifying air at the middle portion of the indoor unit, and the third humidification region corresponds to humidifying air at the lower portion of the indoor unit. The upper part, the middle part and the lower part of the indoor unit are relative, and in some embodiments, the upper part, the middle part and the lower part may be divided on the basis of the length of the outlet air area of the indoor unit, or the lengths of the upper part, the middle part and the lower part are increased in sequence.

It can be understood that, after the humidifying device is turned on, if it is detected that the humidity value is smaller than a first preset threshold value, all the humidifying areas are adjusted to the first state. And when the humidity value is detected to be greater than or equal to the first preset threshold value and smaller than the second preset threshold value, the first humidification region and the second humidification region are adjusted to the first state, if the humidification ports corresponding to the first humidification region and the second humidification region output air, the humidification ports corresponding to the third humidification region are kept in the second state, so that the third humidification region cannot output air normally, at the moment, the middle part and the upper part corresponding to the air outlet of the indoor unit are humidified, the lower part corresponding to the air outlet of the indoor unit is not humidified, the indoor lower layer corresponding to the lower part of the air outlet is prevented from having high humidity, the indoor upper layer and the indoor lower layer corresponding to the upper part and the middle part of the air outlet are prevented from being humidified continuously, and the humidity difference value of each indoor position is reduced.

And if the humidity value is detected to be larger than the second preset threshold value, controlling the first humidifying area to be kept in the first state.

Optionally, when the humidity value is greater than or equal to the first preset threshold and smaller than the second preset threshold, the first humidification region and the second humidification region are adjusted to the first state for a third preset time interval, and if the humidity value is greater than or equal to the second preset threshold, the second humidification region is adjusted to the second state.

That is, in the above-mentioned humidification process, detect the indoor humidity value in place in real time or regularly, if after the humidification, the humidity value is greater than or equal to the second is predetermine the threshold value (and be less than the third and predetermine the threshold value, the third is predetermine the threshold value and is greater than the second is predetermine the threshold value), then control adjustment the regional adjustment subassembly that corresponds of second humidification will the regional adjustment of second humidification is to the second state, only keeps the regional air-out of first humidification, or keeps the regional air output of first humidification is the biggest, so, through discharging more air through the humidification to indoor upper strata area, even the air after the humidification sinks, also can make the humidity balance of indoor each position, improves the comfort level of indoor environment, improves the effect of humidity control.

Further, a third preset threshold is preset in this embodiment, and when the humidity value is greater than or equal to the third preset threshold, the humidifying device is controlled to stop humidifying. Wherein the third preset threshold is greater than the second preset threshold. That is, in this embodiment, when indoor humidity value is greater than or equal to the third preset threshold, judge that the humidity of each indoor position all reaches preset target humidity, indoor meeting humidity requirement this moment controls humidification device stops the humidification, avoids humidity too high, influences the comfort level.

In addition, referring to fig. 1 to 7, the air outlet states of the humidification regions of the indoor unit operated by the control methods of the indoor unit in the above embodiments are adjusted by the adjusting unit 30. In some embodiments, the adjustment assembly 30 includes a switching damper 31, and the switching damper 31 is movably disposed between two adjacent humidification regions in the humidification duct 22 to adjust the air flow rate in the humidification duct 22 passing through the switching damper 31.

The humidifying areas are arranged on both sides of the switching baffle 31, the switching baffle 31 adjusts the air flow rate of the humidifying area flowing through the switching baffle 31, each switching baffle 31 actually adjusts the humidifying area along the air flowing direction of the humidifying pipeline 22, and the switching baffle 31 is far away from the humidifying area on the side of the air inlet end of the humidifying pipeline 22, so that the air outlet state of the humidifying area on the side of the air inlet end of the humidifying pipeline 22 or the first humidifying area does not need to be adjusted by the switching baffle.

For example, the humidifying conduit 22 sequentially conveys air from the air inlet end to the side away from the air inlet end, so that the air flow direction is from the air inlet end to the side away from the air inlet end, and in the embodiment where the first humidifying area, the second humidifying area and the third humidifying area are sequentially arranged along the air flow direction, the humidified air passes through the first humidifying area after the humidifying device 20 is started, and then sequentially passes through the second humidifying area and the third humidifying area. If the humidity value in the room after the humidification device 20 is started is greater than or equal to the second preset threshold value, the control terminal does not control any adjusting assembly 30, and each adjusting assembly 30 is kept at the second position, so that the air in the humidification duct 22 can only flow to the first humidification region and is discharged from the first humidification region to the heat exchange air duct. Therefore, only the humidification port corresponding to the first humidification region is kept open, and the humidification ports corresponding to other humidification regions are closed or small-flow air outlet is kept. Before the humidifying device 20 is started, the switching baffle 31 is located at the second position, the humidifying area is adjusted to be in the second state, and when the switching baffle 31 is switched to the first position, the humidifying area is adjusted to be in the first state. And if the second humidification area needs to be adjusted to the first state, the switching position of the switching baffle 31 between the first humidification area and the second humidification area is controlled, so that the humidified air flows to the second humidification area after passing through the first humidification area under the action of the switching baffle, is discharged to the heat exchange air duct 15 through the humidification ports of the first humidification area and the second humidification area, and is discharged out of the humidification ports corresponding to the first humidification area and the second humidification area. Similarly, if the third humidification area needs to be adjusted to the first state, the switching position of the switching baffle 31 between the second humidification area and the first humidification area is controlled, so that the humidified air flows to the second humidification area and the third humidification area after passing through the first humidification area under the action of the switching baffle 31, and the humidified air is discharged from the humidification ports corresponding to the first humidification area, the second humidification area and the third humidification area.

In an alternative embodiment, the step of controlling the starting of the humidifying device 20 of the indoor unit 100 includes: acquiring an operation mode of an indoor unit; when the operation mode is a heating mode, starting an ultrasonic humidifying module of the humidifying device; and when the operation mode is other than the heating mode, adopting a wet film evaporation module.

The humidifier in this embodiment includes a wet film evaporation module and an ultrasonic humidification module. When the indoor unit starts a heating mode, the ultrasonic humidifying module is selected to be used for humidifying, and when the indoor unit starts other modes except the heating mode, the wet film evaporation module is selected to be used for humidifying. Based on supersound humidification module humidification efficiency is high, and life is short, and is with high costs, this embodiment sets up two kinds of humidification modules, and adopts different modes to carry out the humidification under different modes, when guaranteeing humidification efficiency under the heating mode, can prolong the life of supersound humidification module.

The fourth embodiment:

this embodiment is based on the first embodiment or the second embodiment, and optionally, the humidification process in this embodiment is applied to the heating mode. Referring to fig. 14, the control method further includes:

step S30, obtaining the operation mode of the indoor unit;

step S40, when the operation mode is a heating mode, judging whether the indoor humidity value of the indoor unit is less than or equal to the first preset threshold value;

if yes, go to step S10.

Optionally, the control method further comprises;

if not, that is, when the operation mode is the heating mode and the humidity value is greater than the first preset threshold value, executing step S50, and detecting the indoor humidity value after a preset time interval;

step S60, if the humidity value is less than or equal to the first preset threshold, adjusting at least one humidification area near the top of the indoor unit to the first state.

That is, the heating mode is started, and when the humidity value in the room where the indoor unit is located is detected to be less than or equal to the first preset threshold value, the humidification is started. And when the heating mode is started, but the humidity value in the room where the indoor unit is located is detected to be greater than the first preset threshold value, the humidification does not need to be started, the humidity value in the room is detected in real time or at regular time in the heating process, and the humidification is started after the humidity value is reduced to be lower than the first preset threshold value. Or when the operation mode is the non-heating mode, the humidification does not need to be started, and the step S10 is not executed.

Because the indoor space is dry in the heating mode, the humidifying effect in the heating mode can be improved by adopting the humidifying mode in the heating mode. In other modes before the heating mode, the indoor relative humidity is higher, and the humidification can be performed in other modes, so that the loss of the humidification device is reduced.

Optionally, after the humidification device is started, based on that the humidity value is less than or equal to the first preset threshold, high-grade humidification is started, and if all humidification areas are adjusted to the first state, all humidification areas all supply humidified air to the heat exchange air duct, so that the indoor humidity value is uniformly and rapidly increased.

Optionally, in order to avoid that the local humidity value is increased too fast, which results in high local humidity, after the first preset time interval, whether the humidity value is greater than or equal to the first preset threshold is detected again, if so, the humidification amount is reduced, and the middle-level humidification is switched. If part of the humidifying area is adjusted to the second state, if the humidifying area close to the bottom of the shell is adjusted to the second state, the humidifying area stops supplying air to the heat exchange air duct. Alternatively, if the humidity value is relatively high, e.g., greater than a second predetermined threshold, the number of humidification regions adjusted to the second state is greater (low level humidification), e.g., only the humidification regions partially near the top of the housing are maintained in the first state, while the other humidification regions are adjusted to the second state.

It can be understood that, in the embodiment, when the heating mode is started and the humidity value in the room where the indoor unit is located is detected to be greater than the first preset threshold, humidification does not need to be started, in the heating process, the humidity value in the room is detected in real time or at regular time, and after the humidity value is reduced to be lower than the first preset threshold, humidification is started. When the humidification is started again, the humidification mode can be adopted, such as high-grade humidification, then middle-grade humidification and finally low-grade humidification, until the indoor humidity value reaches the target humidity.

Or, in a preferred embodiment, after the humidity value drops below the first preset threshold, only low-level or medium-level humidification is started, for example, only at least one humidification area near the top of the indoor unit is adjusted to the first state, so that part of humidification areas supply air to the heat exchange air duct. Because indoor humidity descends to low humidity value from high humidity value, humidity value can not be on the low side, if open high-grade humidification this moment, indoor humidity value promotes too fast, leads to indoor humidity value on the contrary on the high side easily, consequently adopts low-grade humidification, can slow down humidity value lifting amplitude for indoor humidity floats slowly, makes the indoor environment keep comfortable.

In one embodiment, if the operation mode is a heating mode and the humidity value of the indoor unit is less than or equal to the first preset threshold (e.g., 40%), and after the high-level humidification is performed for a set time, if it is detected that the humidity value of the indoor unit is greater than the first preset threshold, switching to the middle-level humidification (e.g., adjusting the third humidification region to the second state and maintaining the first humidification region and the second humidification region in the first state), and if it is detected that the humidity value of the indoor unit is less than or equal to the first preset threshold, maintaining the high-level humidification; after the middle-level humidification is performed for a set time, if the humidity value in the room is detected to be greater than the first preset threshold, the humidification device 20 is turned off after the middle-level humidification is continuously maintained for the set time or the humidification device is switched to the low-level humidification (for example, the second humidification area and the third humidification area are adjusted to the second state, and the first humidification area is maintained in the first state), and if the humidity value in the room is detected to be less than or equal to the first preset threshold, the humidification device is switched to the high-level humidification; after the middle-grade humidification is carried out for a set time, if the humidity value in the room is detected to be greater than the first preset threshold value, the humidification device 20 is closed after the low-grade humidification is continuously kept for the set time, and if the humidity value in the room is detected to be less than or equal to the first preset threshold value, the middle-grade humidification is switched to. In this way, the humidity level in the room can be kept around the first preset threshold.

In one embodiment, in an embodiment, if the operation mode is a heating mode and the humidity value of the indoor space where the indoor unit is located is greater than the first preset threshold (for example, 40%), and after the heating mode operates for at least a set time (at this time, humidification is not turned on), if it is detected that the humidity value of the indoor space is less than or equal to the first preset threshold, switching to low-grade humidification; after the low-grade humidification is carried out for a set time, if the humidity value in the room is detected to be greater than a first preset threshold value, the low-grade humidification is continuously kept for the set time, then the humidification device 20 is closed, and if the humidity value in the room is detected to be less than or equal to the first preset threshold value, the middle-grade humidification is switched; after the middle-grade humidification is carried out for a set time, the humidifying device 20 is closed, or if the humidity value in the room is detected to be smaller than or equal to a first preset threshold value, the high-grade humidification is switched to; after the high-level humidification is performed for a set time, the humidifying device 20 is turned off.

Optionally, in a further embodiment, the control method further includes: and when the operation mode is a heating mode, judging whether the humidifying device 20 meets the starting condition, and if so, executing the step of judging whether the indoor humidity value of the indoor unit is smaller than or equal to the first preset threshold. If not, outputting abnormal prompt information.
