Description

Technical Field

[0001] The present application relates to the technical field of air conditioners, and in particular to a wall-mounted air conditioner. Background Art

[0002] Air conditioning, also known as air conditioners, refers to equipment that manually adjusts and controls parameters such as temperature, humidity, and flow rate of the ambient air within a building or structure. Fresh air air conditioners are a healthy and comfortable form of air conditioning with a fresh air function. In addition to the temperature control functions of traditional air conditioners for heating or cooling, they also incorporate a fresh air module to purify oxygen-rich outdoor air and introduce it into the room, achieving circulation and ventilation between indoor and outdoor air.

[0003] In conventional wall-mounted air conditioners, the fresh air fan and the heat exchange fan are each connected to a motor, operating independently of each other. This allows the fresh air function to be individually turned on and off by turning the fresh air fan on or off. Currently, some wall-mounted air conditioners use the same drive motor to drive both the fresh air fan and the heat exchange fan. This saves one drive motor and reduces the manufacturing cost of the indoor unit. Because the fresh air fan and the heat exchange fan are driven by the same motor and rotate synchronously, the fresh air function in these wall-mounted air conditioners cannot be individually turned on and off in the conventional sense.

[0004] Currently, wall-mounted air conditioners with shared drive motors have a switch assembly installed at the fresh air inlet. This switch assembly opens or closes the fresh air inlet to control whether outdoor fresh air can flow into the room, thereby turning the fresh air function on and off. When the user needs to activate the fresh air function separately, indoor air is drawn into the air conditioner housing through the air inlet by the operation of the heat exchange fan and flows back into the room through the air conditioner outlet. By disabling the compressor, the refrigerant cannot circulate between the indoor and outdoor heat exchangers, thus turning off the air conditioner's temperature control function. However, the operation of the heat exchange fan generates noise, and the indoor air flowing back into the room through the air conditioner outlet blows directly onto the user, reducing the user experience. Furthermore, when the temperature difference between the outdoor fresh air and the indoor air is large, the introduction of outdoor fresh air into the room can easily cause human discomfort.

[0005] In view of this, this application is filed. Summary of the Invention

[0006] In response to the shortcomings in the relevant technologies, the present invention provides a wall-mounted air conditioner, which regulates the opening and closing sequence of the fresh air outlet, fresh air inlet and air-conditioning outlet by improving the control logic, so as to avoid the direct blowing of air-conditioning air and loud noise caused by the operation of the heat exchange fan when the fresh air function is turned on alone.

[0084] The present invention is described in detail below by way of exemplary embodiments, but it should be understood that elements, structures, and features of one embodiment may be beneficially combined in other embodiments without further description.

[0085] Figures 1-16 This is a specific embodiment of the wall-mounted air conditioner of the present invention. In this embodiment, the wall-mounted air conditioner includes an indoor unit and an outdoor unit. The outdoor unit is arranged outdoors. The outdoor unit includes a compressor and an outdoor heat exchanger. The indoor unit includes a shell 100, an indoor heat exchanger 200, a heat exchange fan 400, a fresh air module and a drive motor 500.

[0086] like Figure 1 As shown, the shell 100 is used to form the overall appearance of the indoor unit of the wall-mounted air conditioner. The shell 100 has a top and a bottom. The top of the shell 100 and the bottom of the shell 100 are opposite ends, and the direction from the top of the shell 100 to the bottom of the shell 100 is the height direction of the shell 100; the left side of the shell 100 and the right side of the shell 100 are opposite sides, and the direction from the left side of the shell 100 to the right side of the shell 100 is the length direction of the shell 100; the front side of the shell 100 and the back side of the shell 100 are opposite sides, and the direction from the front side of the shell 100 to the back side of the shell 100 is the thickness direction of the shell 100; wherein, the shell 100 is set at the top of the room or the upper space of the room, the front side of the shell 100 is set towards the user, and the back side of the shell 100 is set towards the wall.

[0087] A heat exchange duct is defined within the housing 100. The housing 100 includes an air conditioning inlet 101 and an air conditioning outlet 102, each of which communicates with the heat exchange duct. The air conditioning inlet 101 is located at the top of the housing 100, while the air conditioning outlet 102 is located at the front of the housing 100 and near the bottom, i.e., the air conditioning outlet 102 is located on the lower front side of the housing 100. An air inlet grille is provided at the air conditioning inlet 101 to prevent debris from entering the housing 100.

[0088] like Figure 7 and Figure 8 As shown, the air outlet 102 is located on the lower front side of the housing 100. A first air guide plate 230 is provided at the air outlet 102. The first air guide plate 230 is connected to the housing 100 in an openable and closable manner to open or close the air outlet 102. Since airflow from the air outlet 102 into the room can easily blow directly on the human body, causing discomfort to the user, the rotation angle of the first air guide plate 230 can be adjusted to prevent the airflow from the air outlet 102 into the room from directly blowing on the human body.

[0089] In some embodiments, the first air guide plate 230 has a first set position. When the first air guide plate 230 moves to the first set position, it can prevent the airflow from blowing directly onto the human body. It should be noted that the first set position is manually set. The air-conditioning outlet 102 is usually located diagonally below the front side of the housing 100. When the user is located diagonally below the air-conditioning outlet 102, they are easily blown directly onto the airflow. By setting the first air guide plate 230 to rotate at the air-conditioning outlet 102, the direction of the airflow flowing out of the air-conditioning outlet 102 is changed, thereby preventing the airflow from blowing directly onto the human body. This is common knowledge in the art and will not be elaborated on.

[0090] In other embodiments, when the first air guide plate 230 moves to the first set position, the air flow out of the air-conditioning outlet 102 usually blows obliquely upward.

[0091] In other embodiments, the first air guide plate 230 is disposed along the length of the air outlet 102 so that the first air guide plate 230 can open or close the air outlet 102. The first air guide plate 230 can open or close the air outlet 102 by rotating around a horizontal axis.

[0092] In other embodiments, a second air guide plate 240 is provided between the first air guide plate 230 and the air-conditioning outlet 102. The second air guide plate 240 is arranged close to the indoor heat exchanger 200. The second air guide plate 240 is used to guide the direction of the air flow. Through the operation of the heat exchange fan 400, the air-conditioned air after heat exchange with the indoor heat exchanger 200 is guided to the second air guide plate 240. The second air guide plate 240 guides part of the air-conditioned air to the air-conditioning outlet 102. The second air guide plate 240 guides another part of the air-conditioned air to the first air guide plate 230, and the air-conditioned air is guided to the air-conditioning outlet 102 by the first air guide plate 230.

[0093] It should be noted that the second air guide plate 240 guides the air-conditioning wind to blow toward the first air guide plate 230, and uses the first air guide plate 230 to guide the air outlet direction of the air-conditioning wind to prevent the air-conditioning wind from blowing directly onto the human body.

[0094] It should also be noted that the second air guide plate 240 can also increase the air outlet resistance of the air-conditioning air to reduce the air outlet volume. Therefore, when the wall-mounted air conditioner only turns on the fresh air function, the air volume blown out by the air-conditioning outlet 102 can be reduced, reducing the air outlet noise of the air-conditioning air.

[0095] The second air guide plate 240 has a second set position. When the second air guide plate 240 moves to the second set position, the second air guide plate 240 can guide the airflow passing through the heat exchange fan 400 to the first air guide plate 230. It should be noted that the second set position is also manually set. When the second air guide plate 240 moves to the second set position, the second air guide plate 240 has a good guiding effect on the airflow.

[0096] The second air guide plate 240 is arranged along the length direction of the air-conditioning outlet 102 so that the second air guide plate 240 can guide the air laterally; the second air guide plate 240 moves to the second set position or returns to the initial position from the second set position by rotating around the horizontal axis; wherein, when the second air guide plate 240 is in its initial position, the first air guide plate 230 closes the air-conditioning outlet 102, and the first air guide plate 230 and the second air guide plate 240 do not interfere with each other.

[0097] It should be noted that the first air deflector 230 and the second air deflector 240 move independently of each other. The first air deflector 230 is connected to a first motor, and the second air deflector 240 is connected to a second motor. The first motor and the second motor operate independently of each other, with the first motor driving the first air deflector 230 and the second motor driving the second air deflector 240.

[0098] It should also be noted that, in some embodiments, the second air guide plate 240 moves to the second set position, and the first air guide plate 230 is in the position to close the air-conditioning outlet 102, then the second air guide plate 240 and the first air guide plate 230 will interfere with each other. Therefore, when opening the air-conditioning outlet 102, the first air guide plate 230 is first moved to the first set position, and then the second air guide plate 240 is moved to the second set position. The purpose is that the second air guide plate 240 is used to guide the airflow passing through the heat exchange fan 400 to the first air guide plate 230. If the second air guide plate 240 moves to the second set position first, more airflow will flow to the first air guide plate 230. If the first air guide plate 230 has not moved to the first set position at this time, the airflow and the first air guide plate 230 will easily generate noise, and the first air guide plate 230 will easily block the airflow, affecting the air supply effect. Correspondingly, when the air-conditioning outlet 102 is closed, the second air guide plate 240 is first moved to its initial position, and then the first air guide plate 230 is moved to its initial position.

[0099] In other embodiments, when the air-conditioning outlet 102 is closed, the movement of the second air guide plate 240 may interfere with the movement of the first air guide plate 230 .

[0100] like Figure 2 As shown, the indoor heat exchanger 200 is installed in the housing 100 and located in the heat exchange air duct. It is used to heat the indoor air in the heat exchange air duct to form conditioned air to meet the user's cooling or heating needs. It should be noted that the indoor heat exchanger 200 is located near the air conditioning air inlet 101. It should also be noted that the conditioned air can be cold air, hot air, or even room temperature air.

[0101] The indoor heat exchanger 200 is connected to the outdoor heat exchanger through a pipeline. Refrigerant flows in the pipeline. The compressor is used to drive the flow of refrigerant. The refrigerant in the pipeline flows between the indoor heat exchanger 200 and the outdoor heat exchanger to exchange heat with the indoor air in the heat exchange duct to form air-conditioned air.

[0102] like Figure 3 As shown, the heat exchange fan 400 is mounted on the housing 100 and located within the heat exchange duct. The heat exchange fan 400 is located below the indoor heat exchanger 200. The axial direction of the heat exchange fan 400 extends along the length of the housing 100. The heat exchange fan 400 operates to draw indoor air into the heat exchange duct. After heat exchange in the indoor heat exchanger 200 to form conditioned air, the conditioned air is then directed into the room through the air conditioning outlet 102. It should be noted that the heat exchange fan 400 is a cross-flow fan.

[0103] like Figure 9-10As shown, the fresh air module is used to introduce outdoor fresh air into the room; the fresh air module includes a fresh air volute 700 and a fresh air fan 300. The fresh air volute 700 and the heat exchange fan 400 are distributed along the length of the housing 100. A fresh air duct is defined within the fresh air volute 700. The fresh air fan 300 is installed in the fresh air duct. The fresh air duct is provided with a fresh air inlet 710 and a fresh air outlet 720. The fresh air inlet 710 is connected to the outside, and the fresh air outlet 720 is connected to the air conditioning fresh air outlet 103. It should be noted that the housing 100 is also provided with an air conditioning fresh air outlet 103, which is connected to the fresh air outlet 720 so that the outdoor fresh air flows from the air conditioning fresh air outlet 103 to the room.

[0104] By operating the fresh air fan 300, outdoor fresh air is introduced into the fresh air duct through the fresh air inlet 710, passes through the fresh air outlet 720, and flows into the room through the air conditioning fresh air outlet 103.

[0105] A filter assembly 800 is installed within the fresh air duct to purify the outdoor fresh air flowing into the room. The filter assembly 800 includes a purification frame and a filter. The filter is mounted on the purification frame and is used to filter and purify the outdoor fresh air, preventing impurities and flocs mixed in the outdoor fresh air from entering the room.

[0106] In some embodiments, the fresh air volute 700 is installed on the shell 100, and the fresh air volute 700 is connected to the shell 100 by fasteners such as screws or screws. In order to prevent the vibration generated by the rotation of the fresh air fan 300 from being transmitted to the shell 100 and other components, shock-absorbing rubber is provided between the fasteners and the shell 100 to buffer and absorb vibrations.

[0107] like Figure 4 and Figure 10 As shown, the fresh air fan 300 is a centrifugal fan, which is used to introduce indoor fresh air into the room; through the operation of the fresh air fan 300, the outdoor fresh air is introduced into the fresh air duct from the fresh air inlet 710, and after purification by the filter assembly 800, it passes through the fresh air outlet 720 and flows into the room from the air-conditioning fresh air outlet 103.

[0108] In some embodiments, the fresh air outlet 720 is opened upward, and the air conditioning fresh air outlet 103 is opened at the top of the housing 100 and is arranged near the air conditioning outlet 102. Since the air conditioning fresh air outlet 103 is opened at the top of the housing 100, when the outdoor fresh air flows into the room through the air conditioning fresh air outlet 103, the heat exchange fan 400 is operated to introduce the outdoor fresh air flowing into the room from the air conditioning fresh air outlet 103 into the housing 100 through the air conditioning air inlet 101, and then flows into the room through the air conditioning outlet 102.

[0109] It should be noted that when the first air guide plate 230 is in the first set position and the second air guide plate 240 is in the second set position, the air flow passing through the heat exchange fan 400 can be directed to the first air guide plate 230, and the first air guide plate 230 can direct the air flow passing through the heat exchange fan 400 to the top of the shell 100 and mix it with the fresh air at the air-conditioning fresh air outlet 103.

[0110] The above-mentioned wall-mounted air conditioner includes at least a fresh air function and a temperature control function. The fresh air function is to introduce outdoor fresh air into the room through the fresh air fan 300, and the temperature control function is to introduce indoor air into the first inner cavity 104 through the heat exchange fan 400. After heat exchange through the indoor heat exchanger 200 to form conditioned air, the conditioned air flows into the room and exchanges heat with the indoor air to adjust the indoor ambient temperature.

[0111] In the prior art, the fresh air fan 300 and the heat exchange fan 400 are each connected to a motor, and the fresh air fan 300 and the heat exchange fan 400 operate independently under the drive of their respective motors. In this embodiment, as shown in Figures 1 and 2, the heat exchange fan 400 and the fresh air fan 300 are driven by the same drive motor 500, thereby saving one motor, reducing production costs, and improving assembly efficiency. The heat exchange fan 400 and the fresh air fan 300 operate synchronously, and the heat exchange fan 400 and the fresh air fan 300 are arranged along the same rotation axis 786; wherein, the drive motor 500 can be a single-axis motor or a dual-axis motor.

[0112] When the driving motor 500 is a single-axis motor, the driving motor 500 includes a motor shaft, the motor shaft of the driving motor 500 is connected to the heat exchange fan 400, and the end of the heat exchange fan 400 away from the driving motor 500 is connected to the connecting shaft 110, and the connecting shaft 110 is connected to the fresh air fan 300 to connect the heat exchange fan 400 with the fresh air fan 300, so that the driving motor 500 can drive the heat exchange fan 400 and the fresh air fan 300 to rotate synchronously.

[0113] In some embodiments, the heat exchange fan 400 is provided with a fan sleeve 401 at the other end along the length direction of the shell 100. The fan sleeve 401 is provided with a mounting hole, and the motor shaft of the drive motor 500 extends into the mounting hole to connect the drive motor 500 and the heat exchange fan 400 to each other.

[0114] In other embodiments, the connecting shaft 110 is connected to a bearing component 120 , and the bearing component 120 is used to support the rotation of the connecting shaft 110 ; the housing 100 is provided with a bearing seat 130 , and the bearing component 120 is installed in the bearing seat 130 .

[0115] When the drive motor 500 is a dual-axis motor, the drive motor 500 includes a first motor shaft and a second motor shaft. The first motor shaft and the second motor shaft are coaxially arranged. The first motor shaft is connected to the heat exchange fan 400, and the second motor shaft is connected to the fresh air fan 300, so that the drive motor 500 can simultaneously drive the heat exchange fan 400 and the fresh air fan 300 to rotate synchronously.

[0116] It should be noted that an axial hole 210 is provided on the side of the fresh air volute 700 facing the heat exchange fan 400, and the opening of the axial hole 210 extends along the length direction of the shell 100. The axial hole 210 is used to connect the fresh air duct with the outside of the fresh air volute 700, so that the connecting shaft 110 or the second motor shaft can pass through the axial hole 210 and be connected to the heat exchange fan 400.

[0117] In some embodiments, as Figure 9-10 As shown, the fresh air volute 700 includes a first split shell 730 and a second split shell 740. The first split shell 730 and the second split shell 740 are distributed along the length of the housing 100 and are interconnected. The first split shell 730 and the second split shell 740 together define a first fresh air cavity 750. The second split shell 740 defines a second fresh air cavity 760. The second fresh air cavity 760 and the first fresh air cavity 750 together form a fresh air duct. The fresh air fan 300 is installed in the second fresh air cavity 760, and the filter assembly 800 is located in the first fresh air cavity 750.

[0118] The second split shell 740 is usually designed as a split structure to facilitate the installation of the fresh air fan 300; the second split shell 740 includes a first half shell 741 and a second half shell 742; the first half shell 741 and the second half shell 742 are arranged opposite to each other and jointly form a second fresh air cavity 760; the first split shell 730 and the second half shell 742 are arranged opposite to each other on the side away from the first half shell 741 to jointly form a first fresh air cavity 750.

[0119] The second half shell 742 is provided with a fresh air grille 7421, which is located at the connection point between the first fresh air chamber 750 and the second fresh air chamber 760, thereby connecting the first fresh air chamber 750 and the second fresh air chamber 760. The fresh air inlet 710 is located in the first fresh air chamber 750, and the fresh air outlet 720 is located in the second fresh air chamber 760. The filter assembly 800 is located in the first fresh air chamber 750, so that the filter assembly 800 purifies the outdoor fresh air entering the first fresh air chamber 750 through the fresh air inlet 710. The air in the first fresh air chamber 750, after being purified by the filter assembly 800, passes through the fresh air grille 7421 and enters the second fresh air chamber 760. The fresh air outlet 720 flows out of the air conditioning fresh air vent 103 and into the room.

[0120] In order to install the fresh air volute 700, the fresh air fan 300 and the drive motor 500, as shown in FIG. Figure 6 As shown, the shell 100 is provided with a first inner cavity 104, a third inner cavity 105 and a second inner cavity 106, and the third inner cavity 105, the first inner cavity 104 and the second inner cavity 106 are distributed along the length direction of the shell 100; the first inner cavity 104 is used to install the heat exchange fan 400; the third inner cavity 105 is used to install the drive motor 500; the second inner cavity 106 is used to install the fresh air module.

[0121] In some embodiments, the second inner cavity 106 is separated from the first inner cavity 104 by a first partition, and the first inner cavity 104 is separated from the third inner cavity 105 by a second partition. The first and second partitions can also axially limit the heat exchange fan 400, increasing the reliability of the heat exchange fan 400 installation.

[0122] Since the driving motor 500 drives the heat exchange fan 400 and the fresh air fan 300 to operate simultaneously, the fresh air fan 300 cannot stop working alone, resulting in the fresh air function cannot be turned off when the air conditioner indoor unit is working. Therefore, the above-mentioned wall-mounted air conditioner is provided with a first switch component 770 at the fresh air inlet 710 and a second switch component 780 at the fresh air outlet 720. The first switch component 770 is used to open or close the fresh air inlet 710, and the second switch component 780 is used to open or close the fresh air outlet 720 to control whether the outdoor fresh air is introduced into the fresh air duct, thereby controlling the opening and closing of the fresh air function.

[0123] like Figure 9 As shown, the first switch assembly 770 includes a baffle 772, a first driving member 771, a first gear and a first rack 773. The baffle 772 is arranged at the fresh air inlet 710 in an openable and closable manner. The first driving member 771 is installed on the fresh air volute 700. The rotating shaft 786 of the first driving member 771 is connected to the first gear. The baffle 772 is provided with a first rack 773, and the first gear is engaged with the first rack 773.

[0124] When the fresh air function is turned on, the first driving member 771 drives the first gear to drive the first rack 773 to move, and then drives the baffle 772 to move linearly to open the fresh air inlet 710, so that outdoor fresh air can enter the room; when the fresh air function is turned off, the first driving member 771 drives the first gear to drive the first rack 773 to move, and the baffle 772 moves linearly to close the fresh air inlet 710, thereby preventing outdoor fresh air from entering the room.

[0125] It should be noted that the baffle 772 closing the fresh air inlet 710 can also prevent fresh air from flowing back into the room when the indoor unit of the wall-mounted fresh air air conditioner is turned off, reducing the indoor air noise and wind feeling when the fresh air function is not turned on, and improving the user experience.

[0126] like Figure 11 and Figure 12 As shown, the second switch assembly 780 includes a plurality of guide vanes 781, the length of which is parallel and perpendicular to the length of the fresh air outlet 720. The guide vanes 781 are rotatably connected to the fresh air outlet 720 via a rotating shaft 786. A second drive member 784 is located near one side of the guide vanes 781, and a transmission gear 782 is coaxially fixed to the corresponding guide vane 781 at the end of the rotating shaft 786 near the second drive member 784. The length of the second rack 783 is the same as the direction in which the guide vanes 781 are spaced apart. The second gear 785 meshes with the second rack 783 and drives the second rack 783 to move along its length. The movement of the second rack 783 drives the transmission gears 782 to rotate, thereby controlling the rotation of the guide vanes 781. When the widths of the guide vanes 781 are in the same plane, the guide vanes 781 close the fresh air outlet 720.

[0127] In some embodiments, the direction of the air output through the fresh air outlet 720 can be adjusted according to the flipping direction of the guide vane 781.

[0128] In some embodiments, tooth grooves are formed on both sides of the second rack 783; each transmission gear 782 is disposed on one side of the second rack 783 and meshes with the second rack 783. The second gear 785 meshes with the second rack 783 on a side away from the transmission gear 782.

[0129] In some embodiments, a mounting frame is provided at the fresh air outlet 720. The ends of each guide vane 781 rotate on opposing walls within the mounting frame. A transmission cavity is defined within the mounting frame. The second rack 783, second gear 785, and transmission gear 782 are all located within the cavity. The cavity prevents the second rack 783, second gear 785, and transmission gear 782 from separating. Furthermore, the cavity limits the movement of the second rack 783, improving structural stability.

[0130] When the fresh air function is on, the second driving member 784 drives the second gear 785 to rotate, and the second rack 783 moves horizontally in a horizontal plane under the action of the second gear 785. The transmission gear 782 rotates under the action of the second rack 783 and drives the guide vane 781 to rotate, so that the guide vane 781 opens the fresh air outlet 720. When the fresh air function is off, the second driving member 784 drives the second gear 785 to rotate, and the second rack 783 moves horizontally in a horizontal plane under the action of the second gear 785. The transmission gear 782 rotates under the action of the second rack 783 and drives the guide vane 781 to rotate, so that the guide vane 781 closes the fresh air outlet 720.

[0131] It should be noted that when the fresh air function is turned off, the baffle 772 closes the fresh air inlet 710 to prevent outdoor fresh air from entering the room. However, since the fresh air fan 300 and the heat exchange fan 400 rotate synchronously, if the fresh air outlet 720 is not closed, the air in the fresh air volute 700 will flow into the room from the fresh air outlet 720 under the action of the heat exchange fan 400, and negative pressure will be formed in the fresh air volute 700, which will produce loud noise and affect the user experience. Closing the fresh air outlet 720 by the guide vane 781 can prevent negative pressure from forming in the fresh air volute 700, thereby avoiding a lot of noise when the fresh air function is turned off.

[0132] When the wall-mounted air conditioner needs to turn on the fresh air function separately, the wall-mounted air conditioner can be prevented from exchanging heat for the indoor air by stopping the compressor from working. However, since the heat exchange fan 400 and the fresh air fan 300 rotate synchronously, the indoor air will be introduced into the interior of the shell 100 through the air-conditioning air inlet 101 under the action of the heat exchange fan 400. If the first air guide plate 230 closes the air-conditioning air outlet 102, the indoor air will not circulate smoothly inside the shell 100, generating noise. By opening the air-conditioning air outlet 102 through the first air guide plate 230, the indoor air inside the shell 100 will flow into the room through the air-conditioning air outlet 102, which can avoid the noise generated by the indoor air not circulating smoothly inside the shell 100.

[0133] The wall-mounted air conditioner further includes a controller electrically connected to the drive motor 500, the indoor heat exchanger 200, the first motor, the second motor, the first drive member 771, and the second drive member 784. The controller controls the movement of the first motor, the second motor, the first drive member 771, and the second drive member 784 to reduce noise generated when the wall-mounted air conditioner's fresh air function is activated alone, thereby improving fresh air delivery performance.

[0134] The user can input the fresh air start command to the controller through a remote control or mobile phone APP. The way in which the user inputs the fresh air start command to the controller belongs to conventional technology in this field and will not be described here. After receiving the fresh air start command, the controller controls the first motor, the second motor, the first drive member 771 and the second drive member 784 to move. Specifically, Figure 13 As shown, when the controller receives the instruction to turn on the fresh air, it controls the first motor to drive the first air guide plate 230 to move to the first set position, so that the first air guide plate 230 opens the air-conditioning outlet 102; controls the first driving member 771 to drive the baffle 772 to open the fresh air inlet 710, and controls the second driving member 784 to drive the guide vane 781 to open the fresh air outlet 720; after the first air guide plate 230 moves to the first set position, controls the second motor to drive the second air guide plate 240 to move to the second set position.

[0135] By opening the air-conditioning outlet 102, the fresh air inlet 710, and the fresh air outlet 720 simultaneously, the response speed of the wall-mounted air conditioner is increased and the air intake rate is improved. After the first air guide plate 230 moves to the first set position, the second motor is controlled to drive the second air guide plate 240 to move to the second set position. The design principle is: the second air guide plate 240 is used to cooperate with the first air guide plate 230. After the first air guide plate 230 moves to the first set position, the second air guide plate 240 guides the air flow to the air-conditioning outlet 102. When the second air guide plate 240 moves to the second set position, it has a good guiding effect on the air flow. If the first air guide plate 230 does not move to the first set position and the second air guide plate 240 moves to the second set position, the air flow guided by the second air guide plate 240 may directly blow the first air guide plate 230, resulting in greater noise. The air flow guided by the second air guide plate 240 may also flow from the air-conditioning outlet 102 to the room. Since the first air guide plate 230 has not moved to the first set position at this time, the air flow flowing from the air-conditioning outlet 102 to the room is likely to directly blow the human body. Often, when a wall-mounted air conditioner first introduces outdoor fresh air, users pay more attention to whether it blows directly onto the human body than to the amount of outdoor fresh air. Figure 14 As shown, when the controller receives the instruction to turn off the fresh air, it controls the speed of the drive motor 500 to be reduced to within the preset range; when the speed of the drive motor 500 is reduced to within the preset range, it controls the first drive member 771 to drive the baffle 772 to close the fresh air inlet 710, controls the second drive member 784 to drive the guide vane 781 to close the fresh air outlet 720, and controls the second motor to drive the second air guide plate 240 to return to its initial position; after the second air guide plate 240 returns to its initial position, it controls the first motor to drive the first air guide plate 230 to close the air-conditioning outlet 102.

[0136] Since the wall-mounted air conditioner has the fresh air function enabled independently, when the user inputs a command to turn off the fresh air to the controller via the remote control or mobile phone app, neither the heat exchange fan 400 nor the fresh air fan 300 is required to operate, thereby reducing the speed of the drive motor 500. When the speed of the drive motor 500 decreases to within a preset range, the speed of the fresh air fan 300 also decreases, and the stall noise caused by the operation of the fresh air fan 300 within the fresh air volute 700 caused by closing the fresh air inlet 710 is reduced.

[0137] It should be noted that the actions of reducing the speed of the drive motor 500 to a preset range, closing the fresh air inlet 710 with the baffle 772, closing the fresh air outlet 720 with the drive guide 781, and returning the second air guide 240 to its initial position are all gradual and require a certain amount of time to complete. As the speed of the drive motor 500 decreases to within the preset range, the ability of the fresh air fan 300 to introduce outdoor fresh air gradually decreases, and the amount of outdoor fresh air introduced gradually decreases. At this time, the fresh air inlet 710 also gradually closes, thus not affecting the fresh air fan 300's ability to introduce outdoor fresh air. Although the second air guide 240's return to its initial position weakens the effect of guiding the outdoor fresh air, due to the reduced amount of outdoor fresh air introduced at this time, even if the outdoor fresh air contacts the first air guide 230, the force exerted by the outdoor fresh air on the first air guide 230 is reduced, resulting in less noise. Even if the outdoor fresh air flows directly into the room from the air conditioning outlet 102, the direct impact of the outdoor fresh air on the human body is reduced, thus reducing the discomfort caused by the human body. Therefore, by designing the baffle 772 to close the fresh air inlet 710, the guide vane 781 to close the fresh air outlet 720, and the second air guide plate 240 to return to its initial position simultaneously, the response time when closing the fresh air function is reduced and work efficiency is improved.

[0138] In some embodiments, when the controller receives the instruction to turn off the fresh air, it controls the drive motor 500 to stop rotating.

[0139] It should be noted that after the wall-mounted air conditioner turns on the fresh air alone, the controller receives the instruction to turn off the fresh air, and then the controller controls the drive motor 500 to stop rotating. If the wall-mounted air conditioner turns on the fresh air and temperature control functions at the same time, and the controller receives the instruction to turn off the fresh air, the controller cannot mechanically control the drive motor 500 to stop rotating. At this time, other conditions need to be judged. This is because stopping the drive motor 500 will turn off the fresh air and temperature control functions at the same time. If the user only wants to turn off the fresh air function and the temperature control function is turned on normally, the controller controlling the drive motor 500 to stop rotating will not meet the user's needs, which will not be repeated here.

[0140] In some embodiments, after the first air guide plate 230 moves to the first set position, the baffle 772 opens the fresh air inlet 710, the guide vane 781 opens the fresh air outlet 720, and the second air guide plate 240 moves to the second set position, the controller controls the drive motor 500 to start. By moving the first air guide plate 230, the second air guide plate 240, the baffle 772, and the guide vane 781 into position before starting the drive motor 500, the noise generated when only the fresh air is turned on can be reduced, while also preventing indoor air from directly blowing on the human body.

[0141] In some embodiments, after receiving the command to turn on the fresh air, the controller controls the drive motor 500 to enter the startup phase, and the speed of the drive motor 500 continues to increase; when the speed of the drive motor 500 reaches the set value, the drive motor 500 is controlled to enter the stable output phase, and the drive motor 500 rotates at the set speed.

[0142] In other embodiments, Figure 16 As shown, after the first air guide plate 230 moves to the first set position and the drive motor 500 is in the startup phase, the controller controls the second motor to drive the second air guide plate 240 to the second set position. By moving the second air guide plate 240 to the second set position as the speed of the drive motor 500 increases, the airflow capacity of the fresh air fan and the heat exchange fan is relatively weak before the drive motor 500 reaches the set speed. Therefore, the airflow rate when it flows out of the air conditioner outlet 102 is relatively low, and the direct blowing effect on the human body is relatively weak. This method can shorten the response time of the wall-mounted air conditioner.

[0143] In some embodiments, the controller is integrated on a circuit board. The above-mentioned wall-mounted air conditioner further includes an electric control box 600, which is disposed in the housing 100; and the circuit board is disposed in the electric control box 600.

[0144] When the outdoor temperature is low, turning on the fresh air function of a wall-mounted air conditioner alone will lower the indoor temperature and cause discomfort to the human body. In order to solve this problem, in this embodiment, a temperature sensor is set to detect the outdoor ambient temperature. When the outdoor temperature difference is low, the wall-mounted air conditioner is prevented from turning on the fresh air function alone.

[0145] Specifically, if Figure 15 As shown, a temperature sensor is located outdoors to detect the outdoor ambient temperature. The temperature sensor is electrically connected to the controller. When the controller receives a command to start fresh air, it receives the outdoor ambient temperature information transmitted by the temperature sensor and determines the received temperature information. If the outdoor ambient temperature is less than or equal to a first reference temperature, the controller controls the drive motor 500 to disable activation. If the outdoor ambient temperature is greater than the first reference temperature, the controller controls the drive motor 500 to activate.

[0146] It should be noted that the outdoor ambient temperature will not affect the movement of the first air guide plate 230, the second air guide plate 240, the baffle 772 and the guide vane 781. When the outdoor ambient temperature is less than or equal to the first reference temperature and the controller controls the drive motor 500 to prohibit starting, if the first air guide plate 230, the second air guide plate 240, the baffle 772 and the guide vane 781 do not move, it is easy for users to mistakenly believe that the air conditioner has malfunctioned.

[0147] It should also be noted that although the temperature sensor detects the outdoor ambient temperature in real time, the controller determines the outdoor ambient temperature at certain intervals. Therefore, when the outdoor ambient temperature is less than or equal to the first reference temperature, the controller updates the received outdoor ambient temperature information at certain intervals and determines the received temperature information.

[0148] In some embodiments, when the controller receives a command to turn on fresh air alone, and the outdoor ambient temperature is greater than the second reference temperature and less than or equal to the third reference temperature, the compressor is controlled to not operate, thereby preventing refrigerant from flowing between the indoor heat exchanger 200 and the outdoor heat exchanger. Since the outdoor ambient temperature is generally within the human body's comfortable ambient temperature range, there is no need to adjust the temperature of the outdoor fresh air.

[0149] It should be noted that the first reference temperature, the second reference temperature, and the third reference temperature are affected by factors such as user preferences and the area where the user lives. It should also be noted that the second reference temperature is lower than the third reference temperature.

[0150] In other embodiments, when the outdoor ambient temperature is less than or equal to the second reference temperature, or when the outdoor ambient temperature is greater than the third reference temperature, the outdoor ambient temperature usually exceeds the suitable ambient temperature for the human body. The controller can prompt the user to choose to start the compressor so that the indoor heat exchanger 200 can perform heat exchange and temperature adjustment on the outdoor fresh air, thereby reducing the temperature difference between the outdoor fresh air and the indoor air, thereby reducing the discomfort caused to the human body when the outdoor fresh air is introduced into the room.

[0151] When the driving motor 500 stops running, the controller stops judging the outdoor environment temperature information transmitted by the receiving temperature sensor.

[0152] It should be noted that although the controller is in a state of receiving the outdoor ambient temperature information transmitted by the temperature sensor, the controller only processes the received outdoor ambient temperature information when it receives the command to turn on the fresh air to determine the relationship between the outdoor ambient temperature and the first reference temperature, the second reference temperature, and the third reference temperature. When the controller receives the command to turn off the fresh air, the controller stops processing the received outdoor ambient temperature information.

[0153] The following takes the first reference temperature of -15°C, the second reference temperature of 18°C, and the third reference temperature of 26°C as an example to describe in detail the working principle of the above-mentioned wall-mounted air conditioner.

[0154] When the controller receives a command to enable fresh air, it controls the first motor to drive the first air guide plate 230 to the first set position, controls the first driving member 771 to drive the baffle 772 to open the fresh air inlet 710, and controls the second driving member 784 to drive the guide vane 781 to open the fresh air outlet 720. After the first air guide plate 230 moves to the first set position, the controller controls the second air guide plate 240 to move to the second set position. Simultaneously, the controller receives outdoor ambient temperature information transmitted by the temperature sensor and determines the received temperature information. If the outdoor ambient temperature is less than or equal to -15°C, the controller controls the drive motor 500 to prohibit starting. If the outdoor ambient temperature is greater than -15°C, the controller controls the drive motor 500 to start.

[0155] If the outdoor ambient temperature is greater than or equal to 18°C ​​and the outdoor ambient temperature is less than 26°C, the controller controls the compressor not to start.
