Description

Technical Field

[0001] The present invention relates to the technical field of household appliances, and in particular to an improvement on the structure of an indoor unit of an air conditioner. Background Art

[0002] The existing air conditioner structure is equipped with an air supply fan and an indoor heat exchanger inside the casing, an air inlet is arranged on the rear side of the casing, and an air outlet is arranged on the front side or both sides of the casing. When supplying air, the air supply fan located inside draws the air from the air inlet and passes through the indoor heat exchanger for heat exchange, and then blows it out from the air outlet to achieve the air supply effect.

[0003] However, when this type of air-conditioning structure is in use, the indoor environment needs to remain closed to ensure the cooling or heating effect of the air-conditioning. However, if it is in a relatively closed environment for a long time, especially in the hot summer, it is easy to breed bacteria and viruses.

[0004] With the development of the market, air-conditioning structures with fresh air modules have appeared. By adding fresh air modules, outdoor fresh air is introduced to make the indoor air fresher. However, in this kind of air-conditioning, the fan in the fresh air module generally runs at a certain speed, which can only meet the need of introducing fresh air, and cannot meet users' more requirements for fresh air use, such as the requirement for fresh air natural wind experience. Summary of the invention

[0005] In order to solve the above-mentioned technical problems existing in the air conditioner in the prior art, the present invention provides a new air conditioner structure, which can enable users to experience fresh air and natural wind, improve the user's comfort, and can also ensure the air supply range.

[0006] In order to achieve the above object, the present invention adopts the following technical scheme:

[0007] The present invention provides an air conditioner, comprising: a casing;

[0008] A fresh air module is provided in the housing, and the fresh air module is used to introduce outdoor airflow to obtain fresh air. The fresh air module has:

[0009] Fresh air inlet part, used to introduce outdoor fresh air;

[0010] Fresh air outlet part, used to output fresh air;

[0011] A fresh air fan is used to introduce airflow from the fresh air inlet and send airflow out from the fresh air outlet;

[0012] An air guide component is rotatably arranged on the housing, at least shielding the fresh air outlet, and can at least change the exposed area of ​​the fresh air outlet by rotating to different positions;

[0013] Outdoor temperature sensor, used to obtain the outdoor ambient temperature value;

[0014] The controller is configured to: when the detection value of the outdoor temperature sensor is greater than a set threshold value and when the fresh air module start signal is obtained, control the speed of the fresh air fan to operate in a low-medium-high-medium-low cycle mode;

[0015] The air guide component is controlled to rotate to change the position of the air guide component, so that there is a positive correlation between the area of ​​the fresh air outlet portion exposed by the air guide component and the rotation speed of the fresh air fan.

[0016] In some embodiments of the present application: the air conditioner further comprises:

[0017] The circulation door body is rotatably arranged on the casing, shielding the fresh air inlet portion, and is used to open or close the fresh air inlet portion; the fresh air outlet portion can be shielded by the arranged circulation door body structure, and dust can be prevented from entering the fresh air module when fresh air is not needed;

[0018] When fresh air is needed, the circulation door can be opened to allow fresh air to enter from the fresh air inlet.

[0019] The controller is also configured to control the circulation door to open when the detection value of the outdoor temperature sensor is greater than a set threshold.

[0020] When the outdoor ambient temperature is detected to be greater than the set threshold, it means that the conditions for opening fresh air are met. At this time, the circulation door can be controlled to open first.

[0021] In some embodiments of the present application: a main air conditioning module is also provided in the housing, and the main air conditioning module includes:

[0022] A main air inlet and a main air outlet are arranged on the housing;

[0023] The main air inlet and the main air outlet are mainly used for the air inlet and air outlet of the main air conditioning module.

[0024] The indoor heat exchanger is arranged in the casing to perform heat exchange with the airflow entering the casing; the indoor heat exchanger can perform heat exchange with the airflow sucked by the main air supply fan, thereby achieving the cooling or heating effect of the air conditioner;

[0025] The main air supply fan is located in the housing and is used to suck air from the main air inlet and drive the air to flow through the indoor heat exchanger and then send the air out from the main air outlet. The main air supply fan is mainly used to drive the circulation of air, suck air from the main air inlet and then send it out from the main air outlet.

[0026] An air guide component, the air guide component also shields the main air outlet, and can change the exposed areas of the fresh air outlet and the main air outlet at the same time by rotating to different positions;

[0027] The air guide component is rotatably connected to the casing, and can block and close the fresh air outlet and the main air outlet, or open the main air outlet and the fresh air outlet by rotating relative to the casing.

[0028] The air guide component can rotate, and when it rotates to different positions, the shielding area of ​​the fresh air outlet and the main air outlet is constantly changing, so that the corresponding exposed area of ​​the fresh air outlet and the main air outlet is also constantly changing. By adjusting the rotation position of the air guide component, the size of the exposed area of ​​the fresh air outlet and the main air outlet can be adjusted.

[0029] The controller is further configured to: when the detection value of the outdoor temperature sensor is greater than a set threshold, and when the fresh air module start signal and the main air conditioning module start signal are obtained, control the main air supply fan to operate;

[0030] Controlling the speed of the fresh air fan to operate in a low-medium-high-medium-low cycle mode;

[0031] The air guide component is controlled to rotate to change the position of the air guide component, so that the areas of the exposed fresh air outlet and the main air outlet are positively correlated with the rotation speed of the fresh air fan.

[0032] The speed of the fresh air fan is controlled by a controller to operate in a low-medium-high-medium-low circulation mode. The operation of the main air supply fan of the main air-conditioning module can make the airflow flowing out from the fresh air outlet and the main air outlet finally present a low-medium-high-medium-low circulation change, so that the airflow forms an effect of regularly changing natural wind, thereby realizing the fresh air natural wind experience.

[0033] The controller controls the speed of the fresh air fan to operate in the order of low-medium-high-medium-low, and its inhaled air volume changes with the speed of the fresh air fan of the fresh air module. When the speed of the fresh air fan increases, the inhaled air volume increases, and when the speed of the fresh air decreases, the inhaled air volume decreases. In order to match the change of the air volume of the fresh air fan, the controller controls the rotation position of the air guide component so that the areas of the main air inlet and the fresh air outlet exposed by the air guide component are positively correlated with the speed of the fresh air fan, so that the airflow can be blown out evenly and stably and the air supply range and distance of the airflow can be guaranteed.

[0034] In some embodiments of the present application: the air conditioner has an air conditioning trigger button for turning on the main air conditioning module and a fresh air trigger button for turning on the fresh air module;

[0035] The fresh air trigger button includes an automatic gear trigger button for controlling the fresh air fan to operate in a low-medium-high-medium-low cycle mode. When the automatic gear trigger button is triggered, the fresh air module is turned on;

[0036] The air conditioning trigger button includes a plurality of air supply trigger buttons with different modes. When any of the air supply trigger buttons is triggered, the main air conditioning module is turned on.

[0037] The main air conditioning module can be turned on by triggering any of the air supply trigger buttons, and the fresh air module can be turned on by triggering the automatic gear trigger button.

[0038] In some embodiments of the present application: the air supply trigger button includes a mixed air trigger button. When the mixed air trigger button is triggered, the controller controls the rotational speed of the main air supply fan and the rotational speed of the fresh air fan to change in a positive correlation.

[0039] When the main air-conditioning module is turned on by the single-wind trigger button, the controller controls the main air-conditioning module to operate in a low-medium-high-medium-low cycle mode, and the speed of the fresh air fan changes synchronously with the low-medium-high-medium-low cycle mode.

[0040] In some embodiments of the present application: the air supply trigger button includes a single wind trigger button for controlling the main air supply fan to run at a preset speed. When the single wind trigger button is triggered, the controller controls the main air supply fan of the main air conditioning module to run at a preset speed.

[0041] When the main air-conditioning module is turned on by the single-wind trigger button, the controller controls the main air-conditioning module to run at a preset speed, and controls the speed of the fresh air fan to run in a low-medium-high-medium-low cycle mode.

[0042] In some embodiments of the present application: two main air outlets are provided, which are respectively arranged at two sides of the housing;

[0043] The fresh air outlet is provided with two groups, which are arranged corresponding to the two main air outlets respectively, and each group of the fresh air outlet includes:

[0044] A first fresh air outlet is arranged in parallel with the main air outlet and extends along the height direction of the main air outlet;

[0045] The second fresh air outlet is arranged at the bottom of the main air outlet to discharge fresh air from the bottom.

[0046] In some embodiments of the present application: also include:

[0047] Fresh air module, the controller is configured to: control the fresh air module to be turned on after detecting that the fresh air module is turned on, and control the fresh air module to always remain in the turned-on state during the operation of the fresh air module. When the fresh air module is turned on, the fresh air module is also controlled to start working, and during the turning-on process of the fresh air module, the fresh air module remains in the turned-on state to ensure that the fresh air sent out is fresh and clean.

[0048] In some embodiments of the present application: the controller is configured to control the fresh air fan and the main air supply fan to stop running when receiving the fresh air module shutdown signal and the main air conditioning module shutdown signal. When fresh air natural wind supply is no longer needed, the user can turn off the fresh air module and the main air conditioning module by triggering the fresh air module trigger button and the main air conditioning module trigger button on the remote control, and the controller controls the fresh air fan and the main air supply fan to stop running accordingly.

[0049] In some embodiments of the present application: the controller is configured to: when receiving the fresh air module shutdown signal and the main air conditioning module shutdown signal, control the circulation door to close and the fresh air module to stop working. As time goes by and according to user needs, when fresh air natural wind supply is no longer needed, the user can trigger the fresh air module trigger button on the remote control and the main air conditioning module trigger button to turn off the fresh air module and the main air conditioning module. After receiving the fresh air module and the main air conditioning module shutdown signal, the controller controls the circulation door to close accordingly and the fresh air module to stop working.

[0050] The technical solution of the present invention has the following technical effects compared with the prior art:

[0051] The air conditioner in the present invention can control the speed of the fresh air fan through a controller to operate in a low-medium-high-medium-low circulation mode, so that the airflow flowing out from the fresh air outlet portion can eventually present a low-medium-high-medium-low circulation change, so that the airflow forms an effect of regularly changing natural wind, thereby realizing the fresh air natural wind experience.

[0052] When the controller controls the speed of the fresh air fan to operate in the order of low-medium-high-medium-low, its inhaled air flow rate changes with the change of the fresh air fan speed of the fresh air module. When the fresh air fan speed becomes larger, the inhaled air flow rate increases, and when the fresh air speed becomes smaller, the inhaled air flow rate decreases. In order to match the change of the air flow rate of its fresh air fan, the controller controls the rotation position of the air guide component so that the areas of the main air inlet and the fresh air outlet exposed by the air guide component are positively correlated with the speed of the fresh air fan. That is, when the speed of the fresh air fan is large, the air guide component is controlled to rotate and open at a larger angle to increase the exposed areas of the main air inlet and the fresh air outlet; when the speed of the fresh air fan becomes smaller, the air guide component is controlled to rotate and open at a smaller angle to reduce the exposed areas of the main air inlet and the fresh air outlet.

[0053] This not only avoids the problem of direct blowing, ensures the user's comfort, but also ensures the air supply distance and range. BRIEF DESCRIPTION OF THE DRAWINGS

[0066] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0067] In the description of the present invention, it should be understood that the terms "center", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship are based on the orientation or position relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0068] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected" and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances. In the description of the above embodiments, specific features, structures, materials or characteristics can be combined in any one or more embodiments or examples in a suitable manner.

[0069] The terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, unless otherwise specified, "plurality" means two or more.

[0070] The present invention provides an embodiment of an air conditioner that performs a refrigeration cycle of an indoor unit of an air conditioner by using a compressor, a condenser, an expansion valve, and an evaporator. The refrigeration cycle includes a series of processes involving compression, condensation, expansion, and evaporation, and supplies refrigerant to air that has been conditioned and heat-exchanged.

[0071] The compressor compresses the refrigerant gas in a high temperature and high pressure state and discharges the compressed refrigerant gas. The discharged refrigerant gas flows into the condenser. The condenser condenses the compressed refrigerant into a liquid phase, and the heat is released to the surrounding environment through the condensation process.

[0072] The expansion valve expands the high-temperature and high-pressure liquid refrigerant condensed in the condenser into a low-pressure liquid refrigerant. The evaporator evaporates the refrigerant expanded in the expansion valve and returns the refrigerant gas in a low-temperature and low-pressure state to the compressor. The evaporator can achieve a cooling effect by utilizing the latent heat of evaporation of the refrigerant to exchange heat with the material to be cooled. In the entire cycle, the air conditioner indoor unit can adjust the temperature of the indoor space.

[0073] The outdoor unit of the air conditioner refers to a portion of a refrigeration cycle including a compressor and an outdoor heat exchanger, the indoor unit of the air conditioner includes an indoor heat exchanger, and an expansion valve may be provided in the indoor unit or the outdoor unit.

[0074] The indoor unit is the indoor unit of the air conditioner, and the outdoor unit corresponds to the outdoor unit of the air conditioner.

[0075] The indoor heat exchanger and the outdoor heat exchanger function as a condenser or an evaporator. When the indoor heat exchanger functions as a condenser, the air conditioner indoor unit functions as a heater in a heating mode, and when the indoor heat exchanger functions as an evaporator, the air conditioner indoor unit functions as a cooler in a cooling mode.

[0076] The outdoor unit includes an outdoor fan that generates an airflow of outdoor air passing through the outdoor heat exchanger to promote heat exchange between the refrigerant flowing through the heat transfer tube and the outdoor air.

[0077] The air conditioner indoor unit is also provided with a remote controller, which has the function of communicating with the control unit using infrared or other communication methods, for example. The remote controller is used for the user to perform various controls on the air conditioner indoor unit and realize the interaction between the user and the air conditioner indoor unit.

[0078] The refrigerant circuit includes a compressor, an outdoor heat exchanger, an expansion valve, a liquid receiver, and an indoor heat exchanger. The indoor heat exchanger and the outdoor heat exchanger work as condensers or evaporators. The compressor sucks in refrigerant from the suction port and discharges the refrigerant compressed inside to the indoor heat exchanger from the discharge port.

[0079] The expansion valve is arranged between the outdoor heat exchanger and the indoor heat exchanger. The expansion valve has the function of expanding and reducing the pressure of the refrigerant flowing between the outdoor heat exchanger and the indoor heat exchanger. The expansion valve is configured to be able to change the opening degree. By reducing the opening degree, the flow resistance of the refrigerant passing through the expansion valve increases, and by increasing the opening degree, the flow resistance of the refrigerant passing through the expansion valve decreases.

[0080] The indoor unit of the air conditioner includes a casing 100 , in which a fresh air module 200 is arranged, and the fresh air module 200 is used to introduce outdoor airflow to obtain fresh air.

[0081] The fresh air inlet portion 210 is a fresh air inlet port when set, which has a fresh air duct with a relatively long length extending outward from the fresh air duct. The fresh air inlet port is set at the end of the fresh air duct, and the airflow is introduced into the fresh air duct through the fresh air inlet port.

[0082] Since the fresh air duct is relatively long, in order to shield the fresh air duct, the fresh air module 200 is also correspondingly provided with a circulation door body, and the circulation door body is used to shield the fresh air duct.

[0083] The circulation door body can move relative to the casing 100 to open or close the fresh air inlet portion 210 and shield the fresh air duct at the same time.

[0084] When the fresh air module 200 is not turned on, the fresh air inlet 210 can be shielded by the circulation door to prevent external dust from entering. When fresh air needs to be introduced, the circulation door is opened to ensure that fresh air can be introduced.

[0085] A fresh air outlet 220, for outputting fresh air, which is arranged around the main air outlet 410;

[0086] The fresh air outlet portion 220 is a fresh air outlet. The outdoor fresh air sucked in by the fresh air fan is sucked in by the fresh air fan and then blown out through the fresh air outlet portion 220 and transported to the room.

[0087] The fresh air fan is used to introduce airflow from the fresh air inlet portion 210 and send the airflow out from the fresh air outlet portion 220 .

[0088] The air guide member 300 is rotatably disposed on the housing 100, at least shielding the fresh air outlet 220, and can at least change the exposed area of ​​the fresh air outlet 220 by rotating to different positions;

[0089] When the air guide component 300 rotates relative to the housing 100 , the fresh air outlet 220 can be opened or closed.

[0090] Since the air guide component 300 is rotatably connected to the housing 100, when it is rotated to different positions, the shielding area of ​​the fresh air outlet 220 also changes accordingly. For example, when it is rotated to the fully open position, the shielding area of ​​the fresh air outlet 220 by the air guide component 300 is 0.

[0091] When it rotates to the middle position, it partially blocks the fresh air outlet 220 .

[0092] When the air guiding component 300 rotates to different positions, the shielding area of ​​the fresh air outlet portion 220 changes, so that the corresponding exposed area of ​​the fresh air outlet portion 220 also changes continuously.

[0093] By adjusting the rotational position of the air guide component 300, the size of the exposed area of ​​the fresh air outlet portion 220 and the main air outlet portion 410 can be adjusted.

[0094] When the exposed area of ​​the fresh air outlet portion 220 is large, the air output volume is large, and when the exposed area of ​​the fresh air outlet portion 220 is small, the air output volume is small.

[0095] Outdoor temperature sensor, used to obtain the outdoor ambient temperature value;

[0096] The controller is configured to: when the detection value of the outdoor temperature sensor is greater than a set threshold value and when the fresh air module 200 is turned on, control the speed of the fresh air fan to operate in a low-medium-high-medium-low cycle mode;

[0097] The air guiding component 300 is controlled to rotate to change the position of the air guiding component 300 , so that there is a positive correlation between the area of ​​the fresh air outlet 220 exposed by the air guiding component 300 and the rotation speed of the fresh air fan.

[0098] The controller controls the speed of the fresh air fan to operate in a low-medium-high-medium-low circulation mode, so that the airflow flowing out from the fresh air outlet 220 can eventually present a low-medium-high-medium-low circulation change, so that the airflow forms an effect of regularly changing natural wind, thereby realizing the fresh air natural wind experience.

[0099] The controller controls the speed of the fresh air fan to run in the order of low-medium-high-medium-low. The air flow rate sucked in changes with the speed of the fresh air fan of the fresh air module 200. When the speed of the fresh air fan increases, the air flow rate sucked in increases. If the area of ​​the fresh air outlet 220 exposed by the air guide component 300 is small at this time, the air flow will directly blow on the user, resulting in poor user experience and comfort.

[0100] When the fresh air speed becomes smaller, the air flow rate it inhales becomes smaller. At this time, if the exposed area of ​​the fresh air outlet 220 is large, the air flow transmission distance will be short, limiting the air supply distance and range.

[0101] In order to match the changes in the airflow rate of the fresh air fan, the controller simultaneously controls the rotation position of the air guide component 300 so that the areas of the main air inlet and the fresh air outlet 220 exposed by the air guide component 300 change in a positive correlation with the rotation speed of the fresh air fan.

[0102] That is, when the speed of the fresh air fan is high, the air guide component 300 is controlled to rotate and open at a larger angle, so that the exposed area of ​​the main air inlet and the fresh air outlet 220 becomes larger. When the speed of the fresh air fan becomes smaller, the air guide component 300 is controlled to rotate and open at a smaller angle, so that the exposed area of ​​the main air inlet and the fresh air outlet 220 becomes smaller.

[0103] This not only avoids the problem of direct blowing, ensures the user's comfort, but also ensures the air supply distance and range.

[0104] In some embodiments of the present application: the air conditioner further comprises:

[0105] The circulation door body is rotatably arranged on the housing 100, shielding the fresh air inlet 210, and is used to open or close the fresh air inlet 210; the position of the fresh air outlet 220 can be shielded by the provided circulation door body structure, and dust can be prevented from entering the fresh air module 200 when fresh air is not needed;

[0106] When fresh air needs to be introduced, the circulation door can be opened to allow fresh air to enter from the fresh air inlet portion 210 .

[0107] The controller is also configured to control the circulation door to open when the detection value of the outdoor temperature sensor is greater than a set threshold.

[0108] When the outdoor ambient temperature is detected to be greater than the set threshold, it means that the conditions for opening fresh air are met. At this time, the circulation door can be controlled to open first.

[0109] In some embodiments of the present application: a main air conditioning module 400 is further provided in the housing 100, and the main air conditioning module 400 includes:

[0110] A main air inlet and a main air outlet 410 are provided on the housing 100;

[0111] The main air inlet and the main air outlet 410 are mainly used for air inlet and air outlet of the main air conditioning module 400 .

[0112] The indoor heat exchanger is arranged in the housing 100 to perform heat exchange with the airflow entering the housing 100; the indoor heat exchanger can perform heat exchange with the airflow sucked by the main air supply fan, thereby achieving the cooling or heating effect of the air conditioner;

[0113] The main air supply fan is located in the housing 100, and is used to suck air from the main air inlet, drive the air flow through the indoor heat exchanger, and then send the air out from the main air outlet 410; the main air supply fan is mainly used to drive the circulation of air flow, suck air from the main air inlet, and then send it out from the main air outlet 410;

[0114] The housing 100 is in the shape of a vertical column, and an air outlet grille is disposed on the outer side of the housing.

[0115] The housing 100 is provided with a main air outlet 410, which is a main air outlet. There are two main air outlets, which are symmetrically arranged at two sides of the housing 100.

[0116] In order to achieve a large-area air outlet effect, when the main air outlet is set, the height is set to be relatively high, extending from top to bottom along the height direction of the casing 100, and its length can be 2 / 3-1 / 2 of the height of the casing 100.

[0117] An air duct assembly is disposed inside the housing 100 , and an air duct for accommodating a main air supply fan is formed by the air duct assembly. The air duct assembly is composed of an air duct plate.

[0118] A main air inlet is provided at the rear of the casing 100, and the main air inlet is the main air inlet. The air flow is introduced into the interior of the casing 100 through the main air inlet, and is driven by the main air supply fan to suck the air flow from the main air inlet, and then passes through the indoor heat exchanger for heat exchange. The air flow after heat exchange is sent out through the main air outlet 410. The air flow that has undergone heat exchange through the indoor heat exchanger is an air flow that has undergone heat exchange, and can achieve a cooling or heating effect accordingly.

[0119] Two main air outlets 410 are provided, and two groups of fresh air outlets 220 are correspondingly provided, which are arranged corresponding to the two main air outlets 410 respectively.

[0120] During the setting, the fresh air outlet portion 220 is arranged along the circumference of the main air outlet portion 410, thereby realizing a compact setting of the air outlet of the entire air conditioner indoor unit.

[0121] Each group of the fresh air outlet 220 includes:

[0122] The first fresh air outlet 221 is arranged in parallel with the main air outlet 410 and extends along the height direction of the main air outlet 410 to form a parallel air outlet arranged in parallel with the main air outlet 410;

[0123] The first fresh air outlet 221 may be formed by extending upward from the fresh air duct.

[0124] The second fresh air outlet 222 is arranged at the bottom of the main air outlet 410 to discharge fresh air from the bottom, forming a series air outlet connected in series with the main air outlet 410, which is equivalent to extending the length of the main air outlet 410 and increasing the length of the air supply port.

[0125] The main air supply fan is a double cross-flow air supply device, including two cross-flow fans, which are arranged vertically and parallel to each other. Each cross-flow fan extends downward from the top of the casing 100 along the height of the casing 100, and its height is about 2 / 3 of the height of the casing 100, so as to achieve a large-area air supply effect;

[0126] During the setting, two cross-flow fans are arranged side by side inside the casing 100, and a separate air duct is formed inside the casing 100 to place each cross-flow fan. The two cross-flow fans are respectively arranged inside the two air ducts to separate the two cross-flow fans, so that the two cross-flow fans will not interfere with each other during operation, thereby ensuring the air outlet effect.

[0127] The air duct is correspondingly connected to the main air inlet and the main air outlet 410 to ensure that the air flow can be sucked into the cross-flow fan and sent out through the cross-flow fan.

[0128] The indoor heat exchanger is arranged in a U shape, between the main air inlet and the main air supply fan, and is used to exchange heat with the suction air flow.

[0129] The U-shaped indoor heat exchanger is equipped with two cross-flow fans.

[0130] The indoor heat exchanger is composed of a plurality of fins and a plurality of heat transfer tubes penetrating the plurality of fins. The indoor heat exchanger functions as an evaporator or a radiator according to the operating state of the indoor unit, and performs heat exchange between the refrigerant flowing in the heat transfer tube and the air passing through the indoor heat exchanger. Although the indoor heat exchanger composed of fins and heat transfer tubes is described here, the indoor heat exchanger used in the present invention is not limited to a fin-tube type heat exchanger, and for example, a heat exchanger using flat porous tubes instead of heat transfer tubes may also be used.

[0131] The airflow enters from the main air inlet at the rear, and is driven by the main air supply fan to flow through the indoor heat exchanger for heat exchange, and then the main air supply fan blows the heat-exchanged airflow out through the main air outlet 410.

[0132] The air guide component 300 also blocks the main air outlet 410 and can change the exposed areas of the fresh air outlet 220 and the main air outlet 410 by rotating to different positions;

[0133] The air guide component 300 is a vertically arranged air guide plate. The height of the air guide plate should be greater than the sum of the heights of the main air outlet 410 and the second fresh air outlet 222. Its width can cover the main air outlet 410 and the first fresh air outlet 221, so that the air guide plate can completely cover the main air outlet 410 and the fresh air outlet 220 when closed.

[0134] The air guide component 300 is rotatably connected to the housing 100 , and can block and close the fresh air outlet 220 and the main air outlet 410 , or open the main air outlet 410 and the fresh air outlet 220 by rotating relative to the housing 100 .

[0135] The air guide component 300 is rotatable. When it is rotated to different positions, the shielding area of ​​the fresh air outlet 220 and the main air outlet 410 also changes continuously, so that the corresponding exposed area of ​​the fresh air outlet 220 and the main air outlet 410 also changes continuously.

[0136] For example, when it is rotated to the fully open position, the shielding area of ​​the air guide component 300 to the main air outlet 410 and the fresh air outlet 220 is 0;

[0137] When it rotates to the middle position, it partially blocks the main air outlet 410 and the fresh air outlet 220 .

[0138] When the air guiding component 300 rotates to different positions, the shielding areas of the main air outlet 410 and the fresh air outlet 220 change, so that the corresponding exposed areas of the main air outlet 410 and the fresh air outlet 220 also change continuously.

[0139] By adjusting the rotational position of the air guide component 300, the size of the exposed area of ​​the fresh air outlet portion 220 and the main air outlet portion 410 can be adjusted.

[0140] The controller is further configured to: when the detection value of the outdoor temperature sensor is greater than a set threshold, and when the fresh air module 200 is turned on, and when the main air conditioning module 400 is turned on, control the main air supply fan to operate;

[0141] Controlling the speed of the fresh air fan to operate in a low-medium-high-medium-low cycle mode;

[0142] The air guide component 300 is controlled to rotate to change the position of the air guide component 300 , so that the areas of the exposed fresh air outlet portion 220 and the main air outlet portion 410 are positively correlated with the rotation speed of the fresh air fan.

[0143] In some embodiments of the present application, the controller is further configured to: when the detection value of the outdoor temperature sensor is greater than a set threshold, and when the fresh air module 200 is turned on, and the main air conditioning module 400 is turned on, control the main air supply fan to operate;

[0144] Controlling the speed of the fresh air fan to operate in a low-medium-high-medium-low cycle mode;

[0145] The air guide component 300 is controlled to rotate to change the position of the air guide component 300 , so that the areas of the exposed fresh air outlet portion 220 and the main air outlet portion 410 are positively correlated with the rotation speed of the fresh air fan.

[0146] By making the exposed areas of the fresh air outlet 220 and the main air outlet 410 positively correlated with the fresh air fan speed, it can be ensured that when the fresh air fan speed is high, the exposed areas of the fresh air outlet 220 and the main air outlet 410 are large;

[0147] When the speed of the fresh air fan is low, the exposed areas of the fresh air outlet 220 and the main air outlet 410 are correspondingly small.

[0148] This control method can adjust the exposed area of ​​the main air inlet and the fresh air outlet 220 according to the change of air flow rate, so that the area used for air outlet matches the air flow rate, ensuring a large air outlet area when the air flow rate is large, which not only allows the air flow to flow out evenly and stably, but also avoids the problem of direct air flow, thereby improving the user experience and comfort.

[0149] On the other hand, when the air flow rate is small, the distance the air flow is delivered can be guaranteed by correspondingly reducing the exposed area of ​​the main air inlet and the fresh air outlet 220, thereby ensuring the air supply range. If a large area air outlet is used when the air flow rate is small, the air supply distance will become shorter and the air supply range will become smaller.

[0150] In addition, the air guide component 300 is provided at the main air outlet 410 and the fresh air outlet 220, so that the airflow of the main air outlet 410 and the fresh air outlet 220 can be blocked by the air guide component 300 to mix the airflows;

[0151] When the air flow is blown out through the main air outlet 410 and the fresh air outlet 220, it will flow through the side wall of the air guide component 300. Due to the blocking effect of the air guide component 300, the air flow directions of the main air outlet 410 and the fresh air outlet 220 will be changed, so that the air flows of the two will intersect and mix together to form a mixed fresh air flow, which is blown out.

[0152] Since the speed of the fresh air fan is continuously circulating and supplying air in a low-medium-high-medium-low cycle mode, the main air supply fan of the main air conditioning module 400 is also supplying air. After the two mixed flows, the airflow finally delivered presents a low-medium-high-medium-low cycle change. Through this high, medium and low continuously changing air supply mode, it forms an air supply experience effect similar to the regular fresh air natural wind, which improves the user's comfort.

[0153] Since the main air-conditioning module 400 is the main air supply module, its corresponding main air supply fan has high power and a long air supply distance, while the fresh air fan has low power and a short air supply distance. After the airflows flowing out of the main air outlet 410 and the fresh air outlet 220 are blocked and mixed by the air guide component 300, the airflow flowing out of the fresh air outlet 220 can be driven by the airflow of the main air-conditioning module 400 to be blown in a farther direction, so that the fresh air flow can be blown farther, and a long-distance fresh air supply experience is achieved.

[0154] In some embodiments of the present application: the air conditioner has an air conditioning trigger button for turning on the main air conditioning module 400 and a fresh air trigger button for turning on the fresh air module 200;

[0155] The fresh air trigger button includes an automatic gear trigger button for controlling the fresh air fan to operate in a low-medium-high-medium-low cycle mode. When the automatic gear trigger button is triggered, the fresh air module 200 is turned on;

[0156] The air conditioning trigger button includes a plurality of air supply trigger buttons of different modes. When any of the air supply trigger buttons is triggered, the main air conditioning module 400 is turned on.

[0157] In some embodiments of the present application: the air supply trigger button includes a mixed air trigger button. When the mixed air trigger button is triggered, the controller controls the rotational speed of the main air supply fan and the rotational speed of the fresh air fan to change in a positive correlation.

[0158] When the main air conditioning module 400 is turned on by the air mixing trigger button, the controller controls the speed of the main air supply fan and the speed of the fresh air fan to change in a positive correlation, that is, the speed of the fresh air fan operates in a low-medium-high-medium-low cycle mode;

[0159] The main air supply fan speed also operates in a low-medium-high-medium-low cycle mode, and the speeds of the two increase or decrease synchronously.

[0160] Since the speed of the fresh air fan continuously circulates and supplies air in a low-medium-high-medium-low cycle mode, the speed of the main air supply fan also operates in a low-medium-high-medium-low cycle mode. After the two are mixed, the airflow delivered presents a low-medium-high-medium-low cycle change. The speed of the fresh air fan and the speed of the main air supply fan are increased or decreased synchronously, which makes the change of the high, medium and low of the blown air flow more obvious, forming a regular fresh air natural wind effect with better experience, and improving the comfort of users.

[0161] In some embodiments of the present application: the air supply trigger button includes a single wind trigger button that controls the main air supply fan to run at a preset speed. When the single wind trigger button is triggered, the controller controls the main air supply fan of the main air conditioning module 400 to run at a preset speed.

[0162] The preset speed of the main air supply fan corresponding to the single wind trigger button can be a high speed or a low speed. When the single wind trigger button is triggered, the main air supply fan runs at a constant speed.

[0163] When the main air-conditioning module 400 is turned on by the single-wind trigger button, the controller accordingly controls the main air-conditioning module 400 to run at a preset speed, and at the same time controls the speed of the fresh air fan to run in a low-medium-high-medium-low cycle mode.

[0164] The airflow flowing out of the fresh air outlet 220 of the fresh air fan and the airflow flowing out of the main air outlet 410 of the main air-conditioning module 400 are mixed. Since the speed of the fresh air fan continuously circulates and supplies air in a low-medium-high-medium-low circulation mode, even if the airflow of the main air-conditioning module 400 is supplied at a preset speed, the two are mixed and the supplied airflow finally presents a low-medium-high-medium-low circulation change. Through this continuously changing air supply mode of high, medium and low, an air supply experience effect similar to regular fresh air natural wind is formed, thereby improving the comfort of users.

[0165] In some embodiments of the present application: also include:

[0166] The controller is configured to control the fresh air module to be turned on after detecting that the fresh air module 200 is turned on, and to control the fresh air module to remain turned on during the operation of the fresh air module 200. After the fresh air module 200 is turned on, the speed starts to increase, and the fresh air module also starts to work at the same time.

[0167] The fresh module is a module built into the indoor unit of the air conditioner for sterilization and disinfection. It can sterilize and disinfect the outflowing airflow. The structure of the fresh module can directly adopt the structure in the existing technology, which will not be described in detail here.

[0168] The airflow is sterilized and disinfected through the freshness module to ensure the cleanliness of the outflowing airflow.

[0169] In some embodiments of the present application: the controller is configured to control the fresh air fan and the main air supply fan to stop running when receiving a signal that the fresh air module 200 is turned off and a signal that the main air conditioning module 400 is turned off. When fresh air natural wind supply is no longer needed, the user can turn off the fresh air module 200 and the main air conditioning module 400 by triggering the fresh air module 200 trigger button and the main air conditioning module 400 trigger button on the remote control, and the controller controls the fresh air fan and the main air supply fan to stop running accordingly.

[0170] In some embodiments of the present application: the controller is configured to: when receiving the fresh air module 200 being turned off signal and the main air conditioning module 400 being turned off signal, control the circulation door to close and the fresh air module to stop working. As time goes by and according to user needs, when fresh air natural wind supply is no longer needed, the user can trigger the fresh air module 200 trigger button and the main air conditioning module 400 trigger button on the remote control to turn off the fresh air module 200 and the main air conditioning module 400. After receiving the fresh air module 200 and the main air conditioning module 400 being turned off signal, the controller controls the circulation door to close accordingly and the fresh air module to stop working.

[0171] In the description of the above embodiments, specific features, structures, materials or characteristics may be combined in a suitable manner in any one or more embodiments or examples.

[0172] The above are only specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto.
