Description

Technical Field

[0001] This invention relates to the field of air conditioning technology, and in particular to an air conditioning inlet and outlet structure and a wall-mounted air conditioning unit. Background Technology

[0002] An air conditioner, or air conditioner, is a device that uses artificial means to regulate and control parameters such as temperature, humidity, and airflow of the air inside a building or structure. An air conditioner generally includes several main parts, such as a cold / heat source unit, a cold / heat medium distribution system, and terminal units, as well as other auxiliary equipment. The main components include: a refrigeration unit, water pumps, fans, and piping systems. The terminal units are responsible for utilizing the distributed cold or heat to specifically process the air conditions, ensuring that the air parameters of the target environment meet certain requirements.

[0003] Most wall-mounted air conditioners currently use a top-intake, bottom-outflow design. Air enters from the top inlet, passes through the evaporator and a single cross-flow fan, and exits from the bottom outlet. The airflow velocities in the room are: outlet velocity > inlet velocity > bottom velocity of the air conditioner. This intake and exhaust structure results in slow temperature changes at the bottom of the unit, making it difficult for users to achieve a comfortable temperature. Furthermore, the airflow at the outlet and inlet easily circulates, causing cold air to re-enter and be drawn back into the unit, significantly reducing indoor air conditioning efficiency.

[0004] Currently, wall-mounted air conditioners do not have a fresh air exchange function. During use, because they are constantly circulating indoor air, the indoor air will become increasingly turbid due to the influence of various odors and pollutants (such as food, dust, sweat, and other factors that affect the air). This will make the air stuffy and polluted, causing users to experience various symptoms such as dizziness and sneezing. Summary of the Invention

[0005] To overcome the problems existing in related technologies, the present invention provides an air conditioner air inlet and outlet structure and an air conditioner wall unit, which has an upper air inlet, a lower air inlet pipe, a lower air outlet and a slit hole for air outlet. The lower air inlet pipe can introduce fresh air from the bottom of the air conditioner wall unit or the outside, and can simultaneously introduce air from the upper and lower parts. The lower air outlet and the slit hole simultaneously discharge air.

[0006] One of the objectives of this invention is to provide an air conditioning inlet and outlet structure:

[0007] Includes an air conditioner housing, which has a lower air outlet and an upper air inlet;

[0008] The air conditioner housing is provided with a main air duct and an auxiliary air duct. The main air duct is provided with an evaporator and a cross-flow fan. The input end and output end of the main air duct are respectively connected to the lower air outlet and the upper air inlet.

[0009] The auxiliary air duct includes an air cavity, an air intake assembly, and an exhaust assembly;

[0010] The main air duct has a slit hole connected to the ventilation cavity on its periphery at the air outlet end. The slit hole is a long and narrow opening. A door panel assembly for opening and closing the slit hole is installed on the air conditioner housing.

[0011] One end of the air cavity is connected to the air inlet assembly, and the other end is connected to the exhaust assembly;

[0012] The air intake assembly includes a fresh air duct and a lower air intake duct. The fresh air duct is connected to the outdoor environment, and the lower air intake duct is connected to the bottom surface of the air conditioner housing.

[0013] This air conditioner has multiple air supply methods, including an upper air inlet, a lower air inlet duct, and an exhaust assembly. The lower air inlet duct can introduce fresh air from the bottom of the air conditioner unit or from the outside, allowing for simultaneous air intake from both the top and bottom, as well as air intake from the top and exhaust from the bottom.

[0014] The air supply modes of this air conditioner's air inlet and outlet structure include ventilation mode, fresh air mode, standard air outlet mode, and mixed flow mode.

[0015] When the air supply mode is ventilation mode, the airflow is divided into two paths:

[0016] One path is for indoor air circulation, with indoor air entering through the upper air inlet and exiting through the lower air outlet;

[0017] Another route involves indoor air entering the air chamber through the lower air intake duct, and then entering the exhaust assembly from the air chamber, which in turn exhausts the indoor air to the outside.

[0018] In ventilation mode, by opening the lower air intake duct and exhaust assembly, indoor air can be exhausted to the outside. While indoor air is being continuously exhausted, outdoor air will enter the room through gaps in doors and windows, thus completing indoor ventilation.

[0019] When the air supply mode is set to fresh air mode, the airflow is divided into two paths:

[0020] One path is for indoor air circulation, with indoor air entering through the upper air inlet and exiting through the lower air outlet;

[0021] Another route involves outdoor air entering the air chamber through the fresh air duct, then entering the main air duct output end through the slit hole and being blown out through the lower air outlet.

[0022] In fresh air mode, by opening the fresh air duct and slit, fresh outdoor air can be introduced into the room, thereby purifying the indoor air.

[0023] When the air supply mode is set to standard air outlet mode, the airflow is divided into two paths:

[0024] One path is for indoor air circulation, with indoor air entering through the upper air inlet and exiting through the lower air outlet;

[0025] The other route is for indoor air to enter the air chamber through the lower air inlet duct, then enter the main air duct output end through the slit hole and be blown out through the lower air outlet.

[0026] In standard air outlet mode, by opening the lower air inlet duct and the slit hole, air can be drawn in from both the top and bottom of the air conditioner at the same time, causing the air below the air conditioner to circulate as well. In standard air outlet mode, the indoor airflow forms two airflow cycles: the airflow at the lower air outlet and the airflow at the lower air inlet duct form one cycle, and the airflow at the lower air outlet and the airflow at the upper air inlet form another cycle. The two airflow cycles make the indoor temperature change more even and faster.

[0027] When the air supply mode is mixed flow, the airflow is divided into two paths:

[0028] One path is for indoor air circulation, with indoor air entering through the upper air inlet and exiting through the lower air outlet;

[0029] The other route involves indoor air entering the air cavity through the lower air inlet duct and outdoor air entering the air cavity through the fresh air duct. After the indoor and outdoor air mix in the cavity, they enter the main air duct output end through the slit hole and are blown out through the lower air outlet.

[0030] In mixed-flow mode, by opening the fresh air duct, the lower air inlet duct, and the slit hole, the air conditioner can mix the air output, making the air below the air conditioner circulate and introducing fresh outdoor air into the room.

[0031] In a preferred embodiment of the present invention, the fresh air duct and the lower air inlet duct are opened and closed by a first valve assembly.

[0032] In a preferred embodiment of the present invention, the air inlet assembly includes an air supply duct;

[0033] Both the fresh air duct and the lower air inlet duct are connected to the air supply duct;

[0034] The air supply duct is connected to the ventilation cavity;

[0035] The first valve assembly is installed inside the air supply duct.

[0036] In a preferred embodiment of the present invention, the first valve assembly includes a rotatable arc-shaped plate valve installed inside the air supply duct and a motor installed on the outer wall of the air supply duct. The output shaft of the motor is connected to the arc-shaped plate valve, and the arc-shaped plate valve is driven to rotate by the rotation of the motor. The arc-shaped plate valve can selectively block the output ends of the fresh air duct and the lower air inlet duct. At this time, outside air or air below the air conditioner can enter through the air inlet assembly. Alternatively, it can simultaneously not block the output ends of the fresh air duct and the lower air inlet duct. At this time, outside air and air below the air conditioner can enter through the air inlet assembly at the same time.

[0037] In a preferred embodiment of the present invention, a turbine fan is installed at the output end of the air supply pipe.

[0038] It should be noted that the turbine fan can pressurize the air cavity, which is connected to the main air duct through a slit. When the slit is opened, the airflow flows out quickly along the guide surface at the bottom of the main air duct. The flow velocity at the slit is greater than the flow velocity at the air outlet of the main air duct. This allows the air output from the air outlet of the main air duct to be delivered further with the assistance of the high-speed airflow output from the slit, thereby increasing the air delivery distance.

[0039] In a preferred embodiment of the present invention, the door panel assembly includes an opening and closing plate and a driving component;

[0040] The opening and closing plate is located at the slit hole, and both ends of the opening and closing plate are rotatably connected to the air conditioner housing via shafts;

[0041] The driving component is located outside the air cavity, and the driving component is connected to the opening and closing plate for transmission to drive the opening and closing plate to rotate;

[0042] In use, the opening and closing plate is driven to rotate forward by the driving component to open the slit hole, and conversely, the opening and closing plate is driven to rotate backward by the driving component to close the slit hole.

[0043] For example, the driving component can be a motor, and the output shaft of the motor is connected to the shaft at one end of the opening and closing plate for transmission. The transmission method can be belt drive, connecting drive, gear drive or transmission via coupling.

[0044] In a preferred embodiment of the present invention, the exhaust assembly includes an exhaust pipe, and a second valve assembly is disposed inside the exhaust pipe;

[0045] The exhaust pipe's outlet is connected to the outdoor environment.

[0046] In a preferred embodiment of the present invention, to prevent mosquitoes from entering, the inlet of the fresh air duct, the inlet of the lower air inlet duct, and the outlet of the exhaust pipe are all equipped with mesh covers.

[0047] In a preferred embodiment of the present invention, the driving component is a second valve assembly;

[0048] The second valve assembly includes an electromagnet, a spring, and a plug with a built-in magnet;

[0049] The exhaust pipe is a straight pipe. The inner end of the straight pipe is sealed by an electromagnet, while the outer end of the straight pipe is not sealed and serves as an exhaust port. A connecting port for a ventilation cavity is provided on the periphery of the inner end of the exhaust pipe.

[0050] The plug is located inside the exhaust pipe, and the plug is connected to an electromagnet via a spring;

[0051] The opening and closing plate is provided with a crank at the end of the shaft on the exhaust pipe side. A slot is opened at the end of the crank, and a pin is slidably arranged in the slot. The pin is connected to a plug.

[0052] The electromagnet can drive the plug to move axially along the exhaust pipe to open either the exhaust port or the opening and closing plate. When the exhaust port is open, the opening and closing plate closes the slit hole, and vice versa.

[0053] When the electromagnet is energized, the plug moves toward the electromagnet, the spring is compressed, and the vent is opened. At the same time, the movement of the plug drives the opening and closing plate to rotate through the crank, so that the opening and closing plate closes the slit hole.

[0054] When the electromagnet is energized, the plug is reset by the spring, the vent is closed, and the movement of the plug drives the opening and closing plate to rotate in the opposite direction through the crank, so that the opening and closing plate opens the slit hole.

[0055] In a preferred embodiment of the present invention, in order to improve the structural strength and transmission stability, a limiting groove is provided at the top of the inner end of the straight pipe, a limiting slider is provided in the limiting groove, and the pin is connected to the plug via the limiting slider.

[0056] In a preferred embodiment of the present invention, the air cavity is a channel arranged horizontally along the length of the air conditioner housing;

[0057] The air cavity is located at the bottom of the outer side of the main air duct;

[0058] The vertical cross-section of the air cavity is teardrop-shaped;

[0059] The outer wall of the air cavity is streamlined.

[0060] Because the inner wall of the air cavity is teardrop-shaped, the airflow can flow at high speed at the slit hole under the action of the turbine fan. According to the Coanda effect, the airflow coming out of the slit hole will flow at high speed along the air guide surface at the bottom of the main air duct, so that a low-pressure area is formed at the bottom of the main air duct output end, thereby driving the surrounding airflow and forming a more natural and comfortable wind. This makes the airflow at the downwind end greater than that at the upwind end, thus achieving an increase in airflow.

[0061] The second objective of this invention is to provide a wall-mounted air conditioner:

[0062] The air conditioner unit includes the aforementioned air inlet and outlet structure.

[0063] The beneficial effects of this invention are as follows:

[0064] The main air duct's input and output ends are connected to the lower air outlet and upper air inlet, respectively. The air outlet end of the main air duct is provided with a slit hole connected to the ventilation cavity. A door panel assembly for opening and closing the slit hole is installed on the air conditioner housing. One end of the air cavity is connected to the air inlet assembly, and the other end is connected to the exhaust assembly. The air inlet assembly includes a fresh air duct and a lower air inlet duct. The fresh air duct is connected to the outdoor environment, and the lower air inlet duct is connected to the bottom surface of the air conditioner housing.

[0065] Compared to existing single top-intake and bottom-outtake air supply methods, this air conditioner's air intake and exhaust structure has multiple air supply methods. It has an upper air intake, a lower air intake duct, and an exhaust assembly. The lower air intake duct can introduce fresh air from the bottom of the air conditioner unit or from the outside, allowing for simultaneous top and bottom air intake, as well as top air intake and bottom exhaust. By opening the lower air intake duct and the slit hole, the air conditioner can achieve simultaneous top and bottom air intake, causing air to circulate below the air conditioner and making indoor temperature changes more even. By opening the fresh air duct and the slit hole, fresh outdoor air can be introduced into the room, achieving the purpose of purifying indoor air. By opening the fresh air duct, the lower air intake duct, and the slit hole, the air conditioner can achieve mixed air output, causing air to circulate below the air conditioner and introducing fresh outdoor air into the room. By opening the lower air intake duct and the exhaust assembly, indoor air can be exhausted to the outside. Attached Figure Description

[0076] Preferred embodiments of the invention will now be described in more detail with reference to the accompanying drawings. While preferred embodiments of the invention are shown in the drawings, it should be understood that the invention can be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that the invention will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.

[0077] Most wall-mounted air conditioners currently use a top-intake, bottom-outflow design. Air enters from the top inlet, passes through the evaporator and a single cross-flow fan, and exits from the bottom outlet. The airflow velocities in the room are: outlet velocity > inlet velocity > bottom velocity of the air conditioner. This intake and exhaust structure results in slow temperature changes at the bottom of the unit, making it difficult for users to achieve a comfortable temperature. Furthermore, the airflow at the outlet and inlet easily circulates, causing cold air to re-enter and be drawn back into the unit, significantly reducing indoor air conditioning efficiency.

[0078] Currently, wall-mounted air conditioners do not have a fresh air exchange function. During use, because they are constantly circulating indoor air, the indoor air will become increasingly turbid due to the influence of various odors and pollutants (such as food, dust, sweat, and other factors that affect the air). This will make the air stuffy and polluted, causing users to experience various symptoms such as dizziness and sneezing.

[0079] Example 1

[0080] To address the aforementioned issues, Embodiment 1 provides an air conditioning intake and exhaust structure and a wall-mounted air conditioning unit, which has an upper air inlet 120, a lower air inlet duct 610, a lower air outlet 130, and a slit hole 140 for air outlet. The lower air inlet duct 610 can introduce fresh air from the bottom of the wall-mounted air conditioning unit or from the outside, allowing for simultaneous intake from both the upper and lower parts. The lower air outlet 130 and the slit hole 140 can simultaneously exhaust air.

[0081] like Figure 1-4 As shown, an air inlet and outlet structure for an air conditioner:

[0082] The air conditioner housing 100 includes a lower air outlet 130 and an upper air inlet 120.

[0083] The air conditioner housing 100 is provided with a main air duct 110 and an auxiliary air duct. The main air duct 110 is provided with an evaporator 300 and a cross-flow fan 400. The input end and output end of the main air duct 110 are respectively connected to the lower air outlet 130 and the upper air inlet 120.

[0084] The auxiliary air duct includes an air cavity 200, an air inlet assembly 600, and an exhaust assembly 700;

[0085] The air outlet end of the main air duct 110 is provided with a slit hole 140 connected to the ventilation cavity 200. The slit hole 140 is a narrow and long opening. A door panel assembly 500 for opening and closing the slit hole 140 is installed on the air conditioner housing 100.

[0086] One end of the air cavity 200 is connected to the air inlet assembly 600, and the other end is connected to the exhaust assembly 700;

[0087] The air intake assembly 600 includes a fresh air duct 620 and a lower air intake duct 610. The fresh air duct 620 is connected to the outdoor environment, and the lower air intake duct 610 is connected to the bottom surface of the air conditioner housing 100.

[0088] This air conditioner has multiple air supply methods in its air intake and exhaust structure. It has an upper air intake 120, a lower air intake duct 610, and an exhaust assembly 700. The lower air intake duct 610 can introduce fresh air from the bottom of the air conditioner unit or from the outside. It can also have air intake from the top and bottom at the same time, or air intake from the top and exhaust from the bottom.

[0089] The air supply modes of this air conditioner's air inlet and outlet structure include ventilation mode, fresh air mode, standard air outlet mode, and mixed flow mode.

[0090] When the air supply mode is ventilation mode, the airflow is divided into two paths:

[0091] One path is for indoor air circulation, with indoor air entering through the upper air inlet 120 and exiting through the lower air outlet 130;

[0092] Another route is for indoor air to enter the air chamber 200 through the lower air inlet duct 610, and then enter the exhaust assembly 700 from the air chamber 200, and the exhaust assembly 700 exhausts the indoor air to the outside.

[0093] It should be noted that the indoor air circulation can be disabled in the ventilation mode, that is, the cross-flow fan 400 and heat exchanger in the main air duct 110 are not working. At this time, the indoor air enters the air cavity 200 through the lower air inlet duct 610, then enters the exhaust assembly 700 from the air cavity 200, and is finally discharged to the outside.

[0094] In ventilation mode, by opening the lower air inlet duct 610 and the exhaust assembly 700, indoor air can be exhausted to the outside. While indoor air is being continuously exhausted, outdoor air will enter the room through gaps in doors and windows, thus completing indoor ventilation.

[0095] When the air supply mode is set to fresh air mode, the airflow is divided into two paths:

[0096] One path is for indoor air circulation, with indoor air entering through the upper air inlet 120 and exiting through the lower air outlet 130;

[0097] Another route is for outdoor air to enter the air cavity 200 through the fresh air duct 620, then enter the main air duct 110 output end through the slit hole 140 and be blown out through the lower air outlet 130.

[0098] In fresh air mode, by opening the fresh air duct 620 and the slit hole 140, fresh outdoor air can be introduced into the room, thereby purifying the indoor air.

[0099] When the air supply mode is set to standard air outlet mode, the airflow is divided into two paths:

[0100] One path is for indoor air circulation, with indoor air entering through the upper air inlet 120 and exiting through the lower air outlet 130;

[0101] Another route is for indoor air to enter the air cavity 200 through the lower air inlet duct 610, then enter the main air duct 110 output end through the slit hole 140 and be blown out through the lower air outlet 130.

[0102] In standard air outlet mode, by opening the lower air inlet duct 610 and the slit hole 140, air can be drawn in from both the top and bottom of the air conditioner simultaneously, causing the air below the air conditioner to circulate as well. In standard air outlet mode, the indoor airflow forms two airflow cycles: the airflow at the lower air outlet 130 and the airflow at the lower air inlet duct 610 form one cycle, and the airflow at the lower air outlet 130 and the airflow at the upper air inlet 120 form another cycle. The two airflow cycles make the indoor temperature change more uniform and faster, solving the problem of slow temperature change at the bottom of the air conditioner unit, which makes it difficult for users under the air conditioner unit to get a suitable temperature.

[0103] When the air supply mode is mixed flow, the airflow is divided into two paths:

[0104] One path is for indoor air circulation, with indoor air entering through the upper air inlet 120 and exiting through the lower air outlet 130;

[0105] Another route is for indoor air to enter the air cavity 200 through the lower air inlet duct 610, and for outdoor air to enter the air cavity 200 through the fresh air duct 620. After the indoor air and outdoor air are mixed in the cavity, they enter the main air duct 110 through the slit hole 140 and are blown out through the lower air outlet 130.

[0106] In mixed-flow mode, by opening the fresh air duct 620, the lower air inlet duct 610 and the slit hole 140, the air conditioner can mix the air output, making the air below the air conditioner circulate and introducing fresh outdoor air into the room.

[0107] Compared to the existing single top-intake and bottom-outtake air supply method, this air conditioner's air intake and exhaust structure has multiple air supply methods. It has an upper air intake 120, a lower air intake duct 610, and an exhaust assembly 700. The lower air intake duct 610 can introduce fresh air from the bottom of the air conditioner unit or from the outside, allowing for simultaneous top and bottom air intake, as well as top air intake and bottom exhaust. By opening the lower air intake duct 610 and the slit hole 140, simultaneous top and bottom air intake can be achieved, allowing the air below the air conditioner to circulate and making the indoor temperature change more even. By opening the fresh air duct 620 and the slit hole 140, fresh outdoor air can be introduced into the room, achieving the purpose of purifying the indoor air. By opening the fresh air duct 620, the lower air intake duct 610, and the slit hole 140, mixed air output can be achieved, allowing the air below the air conditioner to circulate and introducing fresh outdoor air into the room. By opening the lower air intake duct 610 and the exhaust assembly 700, indoor air can be exhausted to the outside.

[0108] Example 2

[0109] Furthermore, in Embodiment 2, based on the above embodiments, the structure of the air intake component 600 in the air conditioning air intake and exhaust structure is further designed.

[0110] like Figure 5-6 As shown, in this embodiment, the fresh air duct 620 and the lower air inlet duct 610 are opened and closed by the first valve assembly; at the same time, the fresh air duct 620 and the lower air inlet duct 610 are opened or closed by the first valve assembly.

[0111] In this embodiment, the air inlet assembly 600 includes an air supply duct 630;

[0112] The fresh air duct 620 and the lower air inlet duct 610 are both connected to the air supply duct 630;

[0113] The air supply duct 630 is connected to the ventilation cavity 200;

[0114] The first valve assembly is installed inside the air supply duct 630.

[0115] Preferably, the first valve assembly includes a rotatable arc-shaped plate valve 650 installed inside the air supply duct 630 and a valve motor 640 installed on the outer wall of the air supply duct 630. The output shaft of the valve motor 640 is connected to the arc-shaped plate valve 650. The arc-shaped plate valve 650 is driven to rotate by the rotation of the valve motor 640. The arc-shaped plate valve 650 can selectively block the output ends of the fresh air duct 620 and the lower air inlet duct 610. In this case, outside air or air below the air conditioner can enter through the air inlet assembly 600. Alternatively, it can simultaneously not block the output ends of the fresh air duct 620 and the lower air inlet duct 610. In this case, outside air and air below the air conditioner can enter through the air inlet assembly 600 at the same time.

[0116] In this embodiment, a turbine fan 660 is installed at the output end of the air supply duct 630;

[0117] When the turbine fan 660 starts, it can drive the airflow from the connected air vent to be continuously input into the air cavity 200, thereby pressurizing the airflow inside the air cavity 200.

[0118] It should be noted that the turbine fan 660 can pressurize the air cavity 200. The cavity is connected to the main air duct 110 through a slit hole 140. When the slit hole 140 is opened, the airflow flows out quickly along the air guide surface at the bottom of the main air duct 110. The flow velocity at the slit hole 140 is greater than the flow velocity at the air outlet of the main air duct 110. This allows the air output from the air outlet of the main air duct 110 to be delivered further with the assistance of the high-speed airflow output from the slit hole 140, thereby increasing the air delivery distance.

[0119] It should be noted that because the high airflow output from the slit hole 140 flows along the air guide surface at the bottom of the main air duct 110, the air entering from the upper air inlet 120 has less contact with the main air duct 110, reducing the viscosity between the air and the air duct, thus increasing the air delivery distance.

[0120] Existing air conditioners often fail to deliver gentle airflow over long distances, making it difficult for people at a distance to quickly perceive temperature changes. However, this embodiment includes a gentle breeze mode in its standard airflow mode. In this mode, the cross-flow fan operates at low speed and low velocity, while the slit 140 outputs a high-speed airflow. This creates a low-pressure zone at the bottom of the main air duct 110's output end, causing the air around the main air duct 110's output end to circulate. Consequently, the airflow at the lower air outlet 130 is significantly greater than that at the upper air inlet 120. Furthermore, this high-speed airflow results in a more continuous, gentle, and natural airflow.

[0121] Example 3

[0122] Furthermore, in Embodiment 3, based on the above embodiments, the structure of the door panel assembly 500 in the air conditioning inlet and outlet structure is further designed.

[0123] In this embodiment, the door panel assembly 500 includes an opening and closing plate 510 and a driving component;

[0124] The opening and closing plate 510 is provided at the slit hole 140, and the two ends of the opening and closing plate 510 are rotatably connected to the air conditioner housing 100 via the shaft portion 520 respectively;

[0125] The driving component is located outside the air cavity 200. The driving component is connected to the opening and closing plate 510 for transmission to drive the opening and closing plate 510 to rotate and open and close the slit hole 140.

[0126] In use, the opening and closing plate 510 is driven to rotate forward by the driving component to open the slit hole 140, and conversely, the opening and closing plate 510 is driven to rotate backward by the driving component to close the slit hole 140.

[0127] For example, the driving component can be a motor, and the output shaft of the motor is connected to the shaft portion 520 at one end of the opening and closing plate 510 for transmission. The transmission method can be belt drive, connecting drive, gear drive or transmission via coupling.

[0128] Example 4

[0129] Furthermore, based on Example 3, Example 4 further designs the structure of the air conditioner air inlet and outlet exhaust assembly 700. In order to reduce costs and simplify the control process, the opening and closing of the exhaust assembly 700 is linked with the opening and closing of the opening and closing plate 510, so that when the exhaust assembly 700 is open, the opening and closing plate 510 closes the slit hole 140 and when the exhaust assembly 700 is closed, the opening and closing plate 510 opens the slit hole 140.

[0130] like Figure 7-8 As shown, in this embodiment, the exhaust assembly 700 includes an exhaust pipe 710, and a second valve assembly is disposed inside the exhaust pipe 710;

[0131] The outlet of the exhaust pipe 710 is connected to the outdoor environment.

[0132] In this embodiment, to prevent mosquitoes from entering, the inlet of the fresh air duct 620, the inlet of the lower air inlet duct 610, and the outlet of the exhaust duct 710 are all equipped with mesh covers 800.

[0133] In this embodiment, the driving component is a second valve assembly;

[0134] The second valve assembly includes an electromagnet 740, a spring 730, and a plug 720 with a built-in magnet;

[0135] The exhaust pipe 710 is a straight pipe. The inner end of the straight pipe is sealed by an electromagnet 740, and the outer end of the straight pipe is not sealed as an exhaust port. A connecting port to the ventilation cavity 200 is provided on the periphery of the inner end of the exhaust pipe 710.

[0136] The plug 720 is disposed inside the exhaust pipe 710, and the plug 720 is connected to the electromagnet 740 via the spring 730;

[0137] The opening and closing plate 510 is provided with a crank 530 at the end of the shaft portion 520 on the side of the exhaust pipe 710. The end of the crank 530 is provided with a strip hole, and a pin is slidably disposed in the strip hole. The pin is connected to the plug 720.

[0138] The electromagnet 740 can drive the plug 720 to move axially along the exhaust pipe 710 to selectively open the exhaust port and the opening and closing plate 510. When the exhaust port is open, the opening and closing plate 510 closes the slit hole 140, and vice versa.

[0139] When the electromagnet 740 is energized, the plug 720 moves toward the electromagnet 740, the spring 730 is compressed, and the vent is opened. At the same time, the movement of the plug 720 drives the opening and closing plate 510 to rotate through the crank 530, so that the opening and closing plate 510 closes the slit hole 140.

[0140] When the electromagnet 740 is de-energized, the plug 720 is reset under the action of the spring 730, and the exhaust port is closed. At the same time, the movement of the plug 720 drives the opening and closing plate 510 to rotate in the opposite direction through the crank 530, so that the opening and closing plate 510 opens the slit hole 140.

[0141] In this embodiment, in order to improve the structural strength and transmission stability, a limiting groove is provided at the top of the inner end of the straight tube, and a limiting slider 750 is provided in the limiting groove. The pin is connected to the plug 720 via the limiting slider 750.

[0142] Example 5

[0143] Furthermore, in Example 5, based on the above examples, the structure of the air conditioning inlet and outlet air components is further designed.

[0144] like Figure 1-4 As shown, in this embodiment, the air cavity 200 is a channel arranged horizontally along the length of the air conditioner housing 100;

[0145] The air cavity 200 is located at the bottom of the outer side of the main air duct 110;

[0146] The vertical cross-section of the air cavity 200 is teardrop-shaped;

[0147] The outer wall of the air cavity 200 is streamlined;

[0148] Because the inner wall of the air cavity 200 is teardrop-shaped, the airflow can flow at high speed at the slit hole 140 under the action of the turbine fan 660. According to the Coanda effect, the airflow coming out of the slit hole 140 will flow at high speed along the air guide surface at the bottom of the main air duct 110, so that a low-pressure area is formed at the bottom of the output end of the main air duct 110 (according to Bernoulli's equation, the faster the flow velocity, the lower the pressure, and a low-pressure area will be generated in the high-speed airflow area), thereby driving the surrounding airflow and forming a more natural and comfortable wind, so that the air volume at the downwind end is greater than the air volume at the upwind end, thus achieving an increase in air volume.

[0149] Example 6

[0150] Furthermore, in embodiment 6, based on the above embodiments, an air conditioner wall unit is provided.

[0151] like Figure 1-8 As shown, a type of wall-mounted air conditioner:

[0152] Includes air conditioner housing 100, cross-flow fan 400 and evaporator 300;

[0153] The air conditioner housing 100 has a lower air outlet 130 and an upper air inlet 120;

[0154] The air conditioner housing 100 is provided with a main air duct 110 and an auxiliary air duct.

[0155] The evaporator 300 and the cross-flow fan 400 are installed in the main air duct 110. The input end and the output end of the main air duct 110 are respectively connected to the lower air outlet 130 and the upper air inlet 120.

[0156] The auxiliary air duct includes an air cavity 200, an air inlet assembly 600, and an exhaust assembly 700;

[0157] The main air duct 110 is provided with a slit hole 140 connected to the ventilation cavity 200 on the periphery of the air outlet end, and a door panel assembly 500 for opening and closing the slit hole 140 is installed on the air conditioner housing 100.

[0158] One end of the air cavity 200 is connected to the air inlet assembly 600, and the other end is connected to the exhaust assembly 700;

[0159] The air intake assembly 600 includes a fresh air duct 620 and a lower air intake duct 610. The fresh air duct 620 is connected to the outdoor environment, and the lower air intake duct 610 is connected to the bottom surface of the air conditioner housing 100.

[0160] This wall-mounted air conditioner features a multi-mode air supply structure, including an upper air inlet 120, a lower air inlet duct 610, and an exhaust assembly 700. The lower air inlet duct 610 can introduce fresh air from the bottom of the air conditioner or from the outside, allowing for simultaneous upper and lower air intake, as well as upper air intake and lower exhaust.

[0161] Specifically, the air supply modes of the air intake and exhaust structure of a wall-mounted air conditioner include ventilation mode, fresh air mode, standard air supply mode, and mixed flow mode.

[0162] When the air supply mode is ventilation mode, the airflow is divided into two paths:

[0163] One path is for indoor air circulation, with indoor air entering through the upper air inlet 120 and exiting through the lower air outlet 130;

[0164] Another route is for indoor air to enter the air chamber 200 through the lower air inlet duct 610, and then enter the exhaust assembly 700 from the air chamber 200, and the exhaust assembly 700 exhausts the indoor air to the outside.

[0165] In ventilation mode, by opening the lower air inlet duct 610 and the exhaust assembly 700, indoor air can be exhausted to the outside. While indoor air is being continuously exhausted, outdoor air will enter the room through gaps in doors and windows, thus completing indoor ventilation.

[0166] When the air supply mode is set to fresh air mode, the airflow is divided into two paths:

[0167] One path is for indoor air circulation, with indoor air entering through the upper air inlet 120 and exiting through the lower air outlet 130;

[0168] Another route is for outdoor air to enter the air cavity 200 through the fresh air duct 620, then enter the main air duct 110 output end through the slit hole 140 and be blown out through the lower air outlet 130.

[0169] In fresh air mode, by opening the fresh air duct 620 and the slit hole 140, fresh outdoor air can be introduced into the room, thereby purifying the indoor air.

[0170] When the air supply mode is set to standard air outlet mode, the airflow is divided into two paths:

[0171] One path is for indoor air circulation, with indoor air entering through the upper air inlet 120 and exiting through the lower air outlet 130;

[0172] Another route is for indoor air to enter the air cavity 200 through the lower air inlet duct 610, then enter the main air duct 110 output end through the slit hole 140 and be blown out through the lower air outlet 130.

[0173] In standard air outlet mode, by opening the lower air inlet duct 610 and the slit hole 140, air can be drawn in from both the top and bottom of the air conditioner at the same time, so that the air below the air conditioner can also circulate, making the indoor temperature change more uniform.

[0174] When the air supply mode is mixed flow, the airflow is divided into two paths:

[0175] One path is for indoor air circulation, with indoor air entering through the upper air inlet 120 and exiting through the lower air outlet 130;

[0176] Another route is for indoor air to enter the air cavity 200 through the lower air inlet duct 610, and for outdoor air to enter the air cavity 200 through the fresh air duct 620. After the indoor air and outdoor air are mixed in the cavity, they enter the main air duct 110 through the slit hole 140 and are blown out through the lower air outlet 130.

[0177] In mixed-flow mode, by opening the fresh air duct 620, the lower air inlet duct 610 and the slit hole 140, the air conditioner can mix the air output, making the air below the air conditioner circulate and introducing fresh outdoor air into the room.
