[0028] Embodiments of the present invention are described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. Embodiments of the present invention are described in detail below.

[0029] Reference below Figure 1-Figure 9 An air conditioner according to an embodiment of the present invention is described, and the air conditioner may adopt a fresh air control method of the air conditioner.

[0030] Combination Figure 1 As shown, the air conditioner according to the present invention can mainly include: an air conditioner indoor unit, an air conditioner outdoor unit, a fresh air module, a remote controller and a controller. Among them, the air conditioner outdoor unit can include: an outdoor housing, an outdoor heat exchanger and an outdoor fan, and the outdoor heat exchanger and the outdoor fan are both arranged in the outdoor housing, and the air conditioner indoor unit can include: an indoor housing, an indoor heat exchanger and an indoor fan, and the indoor heat exchanger and the indoor fan are both arranged in the indoor housing, so that the outdoor housing can play a protective role for the outdoor heat exchanger and the outdoor fan, and the indoor housing can play a protective role for the indoor heat exchanger and the indoor fan, which can prevent the erosion of foreign objects from the outside, and the damage of the outdoor heat exchanger, the outdoor fan, the indoor heat exchanger and the indoor fan caused by the impact of external forces, so as to improve the structural reliability of the outdoor heat exchanger, the outdoor fan, the indoor heat exchanger and the indoor fan, and improve the structural reliability of the air conditioner, and ensure that the air conditioner can work normally.

[0031] Furthermore, a refrigerant circulation loop can be formed between the indoor heat exchanger and the outdoor heat exchanger. When the air conditioner is working, the operation of the outdoor fan can introduce the air flow outside the outdoor casing into the outdoor casing, and form a heat exchange air flow through the heat exchange of the refrigerant in the indoor heat exchanger. The heat exchange air flow is output to the outside of the outdoor casing under the drive of the outdoor fan, and the refrigerant after heat exchange can flow into the indoor heat exchanger. By arranging an air inlet and an air outlet on the indoor casing, the operation of the indoor fan can introduce the air flow outside the indoor casing into the indoor casing through the air inlet, and form a heat exchange air flow through the heat exchange of the refrigerant in the indoor heat exchanger. The heat exchange air flow is output to the outside of the indoor casing through the air outlet under the drive of the indoor fan, so that the air conditioner can deliver wind with suitable temperature to the room, realize the air conditioner's regulating effect on the indoor temperature, ensure the normal operation of the air conditioner, and meet the user's usage needs.

[0032] Specifically, in the present application, the outdoor unit of the air conditioner works together with the indoor unit of the air conditioner, wherein the outdoor heat exchanger can be an evaporator or a condenser, and the corresponding indoor heat exchanger is a condenser or an evaporator, and the air conditioner performs the refrigeration cycle of the air conditioner by using a compressor, an expansion valve, a condenser and an evaporator. The refrigeration cycle includes a series of processes involving compression, condensation, expansion and evaporation, and supplies refrigerant to the air that has been conditioned and heat exchanged. The compressor compresses the refrigerant gas 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. The expansion valve expands the liquid phase refrigerant in a high temperature and high pressure state condensed in the condenser into a low pressure liquid phase 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 refrigeration effect by utilizing the latent heat of evaporation of the refrigerant to exchange heat with the material to be cooled. In the whole cycle, the air conditioner can adjust the temperature of the indoor space. Furthermore, the outdoor fan of the present application can accelerate the flow rate of wind flowing through the outdoor heat exchanger, and the indoor fan of the present application can accelerate the flow rate of wind flowing through the indoor heat exchanger, thereby improving the heat exchange efficiency of the air conditioner and improving the working performance of the air conditioner.

[0033] Furthermore, a fresh air control button is provided on the remote control, and the controller is electrically connected to the remote control and the fresh air module respectively. The controller can be configured to: when the air conditioner is turned on and the indoor fan is running, obtain the number of times the fresh air control button of the remote control sends instructions, and selectively control the fresh air module to operate at a gear associated with the speed of the indoor fan, or at a first fixed gear, or at a second fixed gear, or stop running according to the number of times the fresh air control button of the remote control sends instructions.

[0034] Specifically, when the air conditioner is turned on and the indoor fan is running, the controller can control the operation of the fresh air module, and the fresh air module can introduce outdoor fresh air into the room to realize the exchange of indoor and outdoor air, thereby purifying the indoor air, improving the indoor air quality, and increasing the indoor air oxygen content, thereby ensuring the comfort of indoor users.

[0035] Furthermore, the controller is electrically connected to the remote control, so that the user can input instructions through the fresh air control button on the remote control, the controller can receive the instructions issued by the remote control, and control the fresh air module to operate at different gears according to the received user instructions, so that the user can manually control the operation of the fresh air module according to actual needs, which can expand the control method of the air conditioner, further enhance the user experience, and meet the user's different usage needs in different scenarios.

[0036] Furthermore, the controller can be configured so that when the air conditioner is turned on and the indoor fan is running, the controller can obtain the number of times the fresh air control button sends instructions, and according to the number of times the fresh air control button of the remote control sends instructions, the controller selectively controls the fresh air module to operate at a gear associated with the speed of the indoor fan, or to operate at a first fixed gear, or to operate at a second fixed gear, or to stop operating, so that the operation of the fresh air module and the operation of the indoor fan can be coordinated, and they can be related to each other and independent of each other, thereby making the operation of the air conditioner more flexible and reliable, facilitating the user's control of the air conditioner, and improving the user experience.

[0037] In addition, while ensuring that the user can control the fresh air module through the remote control to meet the different usage needs of the user, there is no need to set different buttons on the remote control, and there is no need to use different buttons to control the fresh air module. Instead, only one fresh air control button is needed to control the different operating gears of the fresh air module. This can reduce the number of buttons on the remote control, make the page of the remote control simpler, and make the size of the remote control smaller, thereby optimizing the structural design of the remote control and even the air conditioner, and improving the user experience.

[0038] Therefore, by setting a fresh air control button on the remote control and configuring the controller, the controller can selectively control the fresh air module to operate at a gear associated with the indoor fan speed, or operate at the first fixed gear, or operate at the second fixed gear, or stop running according to the number of times the fresh air control button sends instructions. Only one fresh air control button is used to control the different operating gears of the fresh air module. Not only can the remote control have fewer buttons and a simpler page, the size of the remote control can also be made smaller, thereby optimizing the structural design of the remote control and even the air conditioner, but the fresh air module and the indoor fan can be interconnected, or work independently, making the air conditioner more flexible and reliable, facilitating user control of the air conditioner, and improving the user experience.

[0039] Further, the controller can be configured as follows: when obtaining the first instruction sent by the fresh air control button of the remote control, the fresh air module is controlled to operate at a gear associated with the indoor fan speed; when obtaining the second instruction sent by the fresh air control button of the remote control, the fresh air module is controlled to operate at a first fixed gear; when obtaining the third instruction sent by the fresh air control button of the remote control, the fresh air module is controlled to operate at a second fixed gear; when obtaining the fourth instruction sent by the fresh air control button of the remote control, the fresh air module is controlled to stop operating, and the cycle is repeated in this order.

[0040] Specifically, the user can send different numbers of instructions to the controller by pressing the fresh air control button multiple times, so that the controller can control the fresh air module to run at different gears according to the number of times the fresh air control button of the remote control sends instructions.

[0041] When the user presses the fresh air control button for the first time, the controller can obtain the first instruction sent by the fresh air control button of the remote control. At this time, the controller can control the fresh air module to operate in a gear associated with the speed of the indoor fan. In this way, the speed of the fresh air module and the speed of the indoor fan can correspond to each other, and the working state of the fresh air module and the indoor fan can be associated, thereby optimizing the control logic of the air conditioner. Not only can the outdoor fresh air be introduced into the room through the fresh air module, but the outdoor fresh air can also be transported to a farther place indoors through the operation of the indoor fan, thereby improving the fresh air exchange performance of the air conditioner, further ensuring the air quality of the indoor environment, and improving the comfort of indoor users.

[0042] When the user presses the fresh air control button for the second time, the controller can obtain the second instruction sent by the fresh air control button of the remote control. At this time, the controller can control the fresh air module to operate at the first fixed gear. This can make the fresh air module and the indoor fan work independently, so that the fresh air module can operate alone at the first fixed gear, thereby introducing outdoor fresh air into the room and ensuring the normal operation of the fresh air module.

[0043] When the user presses the fresh air control button for the third time, the controller can obtain the third instruction sent by the fresh air control button of the remote control. At this time, the controller can control the fresh air module to operate at the second fixed gear. This can make the fresh air module and the indoor fan work independently, and make the fresh air module operate alone at the second fixed gear, so that outdoor fresh air can be introduced into the room, ensuring the normal operation of the fresh air module.

[0044] The first fixed gear and the second fixed gear are different, so when the controller controls the fresh air module to operate at the first fixed gear or the second fixed gear, the efficiency of the fresh air module introducing outdoor fresh air can be adjusted. In actual applications, users can choose between the first fixed gear and the second fixed gear according to actual needs, thereby further meeting different user needs and further improving the user experience.

[0045] When the user presses the fresh air control button for the fourth time, the controller can obtain the fourth instruction sent by the fresh air control button of the remote control. At this time, the controller can control the fresh air module to stop running, thereby realizing the control of the operating status of the fresh air module, so that the user can turn off the fresh air module according to actual needs and stop introducing outdoor fresh air into the room, thereby meeting the user's usage needs, facilitating the user's usage needs, and improving the user's usage experience.

[0046] In this way, the user can press the fresh air control button multiple times to selectively send the first instruction, the second instruction, the third instruction and the fourth instruction to the controller, thereby realizing the control of different operating states of the fresh air module, and making the fresh air module cycle in turn between the gear associated with the speed of the indoor fan, the first fixed gear, the second fixed gear and stop running, thereby realizing the associated control of the fresh air module and the indoor fan, or the independent control of the fresh air module and the indoor fan. The logic of the controller controlling the fresh air module according to the instructions issued by the remote control can be simpler, more reliable and more flexible, thereby facilitating the user's control over the operating state of the fresh air module, making the switching of the operating state of the fresh air module more in line with the user's cognitive habits, and improving the user's experience.

[0047] Furthermore, the first fixed gear is the lowest gear, and the second fixed gear is the highest gear. Specifically, the first fixed gear can be set to the lowest gear of the fresh air module, at which the rotation speed of the fresh air module is the lowest, and the second fixed gear can be set to the highest gear of the fresh air module, at which the rotation speed of the fresh air module is the highest. In this way, when the user sends instructions to the controller through the remote control, not only can the working gear of the fresh air module be adjusted, and the fresh air module can be selectively operated at different rotation speeds to meet different fresh air needs, but also the selection and confirmation of the gear of the fresh air module can be more in line with the user's operating habits and cognitive habits, ensuring that the user can more accurately control the gear of the fresh air module when it is independently operating through the remote control, which can further enhance the user's experience.

[0048] The controller can also be configured to: when the first instruction sent by the fresh air control button of the remote control is obtained, the fresh air module is controlled to operate at a gear associated with the indoor fan speed in a preset speed mapping relationship. Specifically, the controller can be further configured, and a preset speed mapping relationship can be pre-stored in the controller, so that when the first instruction sent by the fresh air control button of the remote control is obtained, the controller controls the fresh air module to operate at a gear associated with the indoor fan speed. The controller can determine the gear of the fresh air module according to the speed of the indoor fan through the preset speed mapping relationship, so that the gear of the fresh air module can be associated with the speed of the indoor fan, and the determination of the gear of the fresh air module can be made simpler and more reliable, and then the control logic of the air conditioner can be made simpler and more reliable, and the working performance of the air conditioner can be made better, while ensuring the normal introduction of outdoor fresh air and improving indoor air quality.

[0049] Furthermore, the fresh air module has multiple gears, and the indoor fan has multiple gears. The preset speed mapping relationship includes: for any gear of the indoor fan, there is one and only one gear of the fresh air module corresponding to it; for any gear of the fresh air module, there is at least one gear of the fan corresponding to it.

[0050] Specifically, the fresh air module is provided with multiple gears. When the fresh air module works at different gears, the working efficiency of the fresh air module is different, and the amount of outdoor fresh air introduced is also different. The indoor fan has multiple gears. When the indoor fan works at different gears, the working efficiency of the indoor unit of the air conditioner is different, and the delivery capacity of the outdoor fresh air is also different. By setting the preset speed mapping relationship, the preset speed mapping relationship includes: for any gear of the indoor fan, there is and only one gear of the fresh air module corresponding to it, and for any gear of the fresh air module, there is at least one gear of the indoor fan corresponding to it, so that According to the gear of any indoor fan, the corresponding gear of the fresh air module can be found through a preset speed mapping relationship, and different gears of indoor fans may correspond to the gear of the same fresh air module. Therefore, while ensuring that the controller can accurately determine the gear of the corresponding fresh air module through the gear of the indoor fan, making the determination of the gear of the fresh air module simpler and more reliable, the gear setting of the fresh air module can be made more reasonable, avoiding frequent changes in the gear of the fresh air module following changes in the gear of the indoor fan, and further optimizing the control logic of the controller over the fresh air module, thereby improving the working performance of the air conditioner.

[0051] It should be noted that in actual applications, the preset speed mapping relationship between the fresh air module and the indoor fan can be adjusted as needed to adapt to the user's usage needs in different scenarios, further improve the intelligence and humanization of the air conditioner, broaden the application scenarios of the air conditioner, and further enhance the user experience.

[0052] The controller can also be configured to: when the fresh air module is in operation, obtain the fourth instruction sent by the fresh air control button of the remote control, stop the fresh air module, and stop the indoor fan. Specifically, the controller can be further configured to obtain the fourth instruction sent by the fresh air control button of the remote control when the fresh air module is in operation. At this time, the controller can control the fresh air module to stop running, and can control the indoor fan to stop running, so that the fresh air function of the air conditioner can be turned off according to actual needs, and the introduction of outdoor fresh air into the room can be stopped, that is, the fresh air module and the indoor fan can be turned off at the same time without the user having to perform multiple operations separately, so that the user's control of the air conditioner can be further facilitated without more cumbersome and complicated operations, which can further enhance the user's experience.

[0053] Combination Figure 2 As shown, the fresh air control method of the air conditioner according to the embodiment of the present invention may include the following steps:

[0054] S1, air conditioner turned on;

[0055] S2. Obtain the number of times the fresh air control button on the remote control sends commands;

[0056] S3. Selectively control the fresh air module to operate at a gear associated with the indoor fan speed, or at a first fixed gear, or at a second fixed gear, or stop operating according to the number of times the fresh air control button of the remote control sends instructions.

[0057] Specifically, when the air conditioner is turned on and the indoor fan is running, the user can send instructions to the controller through the fresh air control button of the remote control. The controller can first obtain the number of times the fresh air control button sends instructions, and according to the number of times the fresh air control button of the remote control sends instructions, selectively control the operation of the fresh air module, adjust the operating status of the fresh air module, so that the fresh air module runs at a gear associated with the speed of the indoor fan, or runs at the first fixed gear, or runs at the second fixed gear, or stops running. In this way, the fresh air module can be controlled by only one fresh air control button, and the operation of the fresh air module and the indoor fan can be coordinated, so that the fresh air module and the indoor fan can be either related to each other or independent of each other, making the fresh air control method of the air conditioner more flexible and reliable, and facilitating user control of the air conditioner.

[0058] Furthermore, combined with Figure 3-Figure 7 As shown, step S3 may include:

[0059] S3-1, when the first instruction sent by the fresh air control button of the remote controller is obtained, the fresh air module is controlled to operate at a gear associated with the indoor fan speed;

[0060] S3-2, when the second instruction sent by the fresh air control button of the remote controller is obtained, the fresh air module is controlled to operate at the first fixed gear;

[0061] S3-3, when the third instruction sent by the fresh air control button of the remote controller is obtained, the fresh air module is controlled to operate at the second fixed gear;

[0062] S3-4. When the fourth instruction sent by the fresh air control button of the remote controller is obtained, the fresh air module is controlled to stop running, and the cycle continues in this order.

[0063] Specifically, when a user uses the air conditioner to regulate the indoor air quality, the user can send different numbers of instructions to the controller by pressing the fresh air control button on the remote control multiple times, so that the controller selectively controls the fresh air module to operate at a gear associated with the indoor fan speed, or at a first fixed gear, or at a second fixed gear, or to stop operating, according to the number of times the fresh air control button on the remote control sends instructions, and the number of times the instructions are sent corresponds to the operating state of the fresh air module, and different numbers of times the instructions are sent can correspond to controlling the fresh air module to operate in different states.

[0064] When the user presses the fresh air control button for the first time, the controller can obtain the first instruction sent by the fresh air control button of the remote control. At this time, the controller can control the fresh air module to operate at a gear associated with the speed of the indoor fan. In this way, the speed of the fresh air module and the speed of the indoor fan can correspond to each other, and the working status of the fresh air module and the indoor fan can be associated, thereby optimizing the control logic of the air conditioner, simplifying the fresh air control method of the air conditioner, and making the fresh air control method of the air conditioner simpler and more reliable.

[0065] When the user presses the fresh air control button for the second time, the controller can obtain the second instruction sent by the fresh air control button of the remote control. At this time, the controller can control the fresh air module to operate at the first fixed gear. This can make the fresh air module and the indoor fan work independently, so that the fresh air module can operate alone at the first fixed gear, thereby introducing outdoor fresh air into the room and ensuring the normal operation of the fresh air module.

[0066] When the user presses the fresh air control button for the third time, the controller can obtain the third instruction sent by the fresh air control button of the remote control, and at this time the controller can control the fresh air module to operate at the second fixed gear, so that the fresh air module and the indoor fan can work independently, so that the fresh air module can operate alone at the second fixed gear, thereby introducing outdoor fresh air into the room, ensuring the normal operation of the fresh air module. Among them, the first fixed gear and the second fixed gear are different, so that the efficiency of the fresh air module introducing outdoor fresh air can be adjusted, and the user can choose between the first fixed gear and the second fixed gear according to actual needs.

[0067] When the user presses the fresh air control button for the fourth time, the controller can obtain the fourth instruction sent by the fresh air control button of the remote control. At this time, the controller can control the fresh air module to stop running, thereby realizing the control of the operating status of the fresh air module, so that the user can turn off the fresh air module according to actual needs and stop introducing outdoor fresh air into the room, thereby further improving the fresh air control method of the air conditioner to meet the user's usage needs.

[0068] In this way, the user can press the fresh air control button to selectively send the first instruction, the second instruction, the third instruction and the fourth instruction to the controller, thereby realizing the control of the fresh air module, and making the fresh air module cycle in sequence between the gear associated with the indoor fan speed, the first fixed gear, the second fixed gear and stop running, thereby realizing the associated control of the fresh air module and the indoor fan, or the independent control of the fresh air module and the indoor fan. This can make the logic of the controller controlling the fresh air module according to the instructions issued by the remote control more flexible and reliable, thereby making the fresh air control method of the air conditioner more flexible and reliable, facilitating the user's control of the operating status of the fresh air module, and improving the user's experience.

[0069] Furthermore, combined with Figure 8 As shown, step S3-1 may also mainly include: S3-1-1. When the first instruction sent by the fresh air control button of the remote control is obtained, the fresh air module is controlled to operate at a gear associated with the indoor fan speed in a preset speed mapping relationship, wherein the preset speed mapping relationship may include: for any gear of the indoor fan, there is one and only one gear of the fresh air module corresponding to it; for any gear of the fresh air module, there is at least one gear of the indoor fan corresponding to it.

[0070] Specifically, the controller may pre-store a preset speed mapping relationship corresponding to the fresh air module and the indoor fan. When the controller obtains the first instruction sent by the fresh air control button of the remote control, the controller may determine the gear of the fresh air module according to the speed of the indoor fan through the preset speed mapping relationship. Moreover, the gear of any indoor fan can find the corresponding gear of the fresh air module through the preset speed mapping relationship. The gears of different indoor fans may correspond to the gear of the same fresh air module. This not only makes the gear of the fresh air module associated with the speed of the indoor fan, and makes the determination of the gear of the fresh air module simpler and more reliable, but also makes the setting of the gear of the fresh air module more reasonable, avoiding frequent changes in the gear of the fresh air module following changes in the gear of the indoor fan. Further, under the premise of ensuring the normal introduction of outdoor fresh air and improving indoor air quality, the control logic of the air conditioner can be made simpler and more reliable, the fresh air control method of the air conditioner can be made more scientific, and the working performance of the air conditioner can be made better.

[0071] Furthermore, combined with Fig. 9 As shown, step S3-4 can also mainly include: S3-4-1. When the fresh air module is in operation, the fourth instruction sent by the fresh air control button of the remote control is obtained, and the fresh air module stops running and the indoor fan stops running. Specifically, when the fresh air module is in operation, if the controller obtains the fourth instruction sent by the fresh air control button of the remote control, the controller can control the fresh air module to stop running, and control the indoor fan to stop running, so that the fresh air module and the indoor fan can be turned off according to actual needs, so that the fresh air module stops introducing outdoor fresh air into the room, that is, the fresh air module and the indoor fan can be turned off at the same time without the user having to control them separately multiple times, so that the control logic of the fresh air control method of the air conditioner can be further optimized, and the user's control of the air conditioner can be further facilitated, and the user's experience can be improved.
