For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections, electrical connections; direct connections, indirect connections through an intermediate medium, and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on the specific circumstances.

[0054] The fresh air structure 100 according to an embodiment of the present invention will be described below with reference to the accompanying drawings.

[0055] like Figure 1 and Figure 2 As shown, the fresh air structure 100 according to an embodiment of the present invention includes a shell 1 and a purification component 2.

[0056] Specifically, such as Figure 1 and Figure 2 As shown, the housing 1 has an outdoor inlet 13 and an outlet 14. Outdoor air can enter the housing 1 through the outdoor inlet 13 and then flow out of the outlet 14 into the room, thereby introducing fresh air into the room and making the indoor air fresher. The outdoor inlet 13 can be connected to the outdoor environment through a fresh air duct. A adapter can also be provided between the outdoor inlet 13 and the fresh air duct to facilitate the connection between the outdoor inlet 13 and the fresh air duct.

[0057] The purification assembly 2 is disposed within the housing 1 and can filter or remove dust from the air entering the housing 1 from the outdoor inlet 13, thereby ensuring the cleanliness of the fresh air entering the room and protecting the health of the user. The purification assembly 2 includes a purification body 21 and a guide plate 22. The purification body 21 is used to purify the air, and the guide plate 22 is used to guide the airflow.

[0058] like Figure 1 and Figure 2 As shown, reference Figure 5 and Figure 6 The outdoor inlet 13 and the outlet 14 are located on opposite sides of the purification component 2, respectively. This ensures that the airflow entering the housing 1 from the outdoor inlet 13 will be purified by the purification component 2 and then flow out from the outlet 14, ensuring the cleanliness of the outdoor air entering the room and the health of the user. The guide plate 22 is connected to the purification body 21 and is used to guide the airflow from the outdoor inlet 13 to the side of the purification body 21 away from the outlet 14. The guide plate 22 can guide the airflow entering the housing 1 from the outdoor inlet 13, better guide the airflow entering the housing 1 from the outdoor inlet 13 to flow to the side of the purification body 21 away from the outlet 14, and then flow to the outlet 14 after being purified by the purification body 21, and then flow from the outlet 14 into the room.

[0059] Among them, after being guided by the guide plate 22, the airflow entering the shell 1 from the outdoor inlet 13 flows more smoothly, avoiding problems such as noise caused by the random flow of airflow.

[0060] In some embodiments of the present invention, Figure 1-Figure 3 、 Figure 6-Figure 8 As shown, the housing also has an indoor inlet 16. Indoor air can enter the housing 1 through the indoor inlet 16 and then flow out of the housing 1 through the outlet 14 to achieve indoor air circulation. At the same time, the purification component 2 can filter or remove dust from the air entering the housing 1 through the indoor inlet 16, thereby purifying the indoor air and ensuring the health of the user.

[0061] like Figure 6-Figure 8As shown, the indoor inlet 16 and the outdoor inlet 13 are located on the same side of the purification component 2, and the indoor inlet 16 and the outlet 14 are located on both sides of the purification component 2. This ensures that the airflow entering the housing 1 from the indoor inlet 16 will be purified by the purification component 2 and then flow out from the outlet 14, ensuring the cleanliness of the air circulating into the room and ensuring the health of the user. The guide plate 22 is also used to guide the airflow from the indoor inlet 16 to the side of the purification body 21 away from the outlet 14, and can guide the airflow entering the housing 1 from the indoor inlet 16, better guiding the airflow entering the housing 1 from the indoor inlet 16 to flow to the side of the purification body 21 away from the outlet 14, and then flow to the outlet 14 after being purified by the purification body 21, and then flow back to the room from the outlet 14.

[0062] In one example of the present invention, the purification body 21 includes a frame and a filter screen. The frame is connected to the guide plate 22, for example, by fasteners, snap-on or integrated settings, and the filter screen is provided on the frame. Of course, the present invention is not limited to this. The purification body 21 may include a frame, and the frame has a discharge needle assembly. The discharge needle assembly is used to discharge, ionize the air, and cause the dust to be charged with static electricity. In addition, the purification body 21 may also include a dust removal net, such as an IFD (Intense Field Dielectric) net. The IFD net is provided on the frame, and the charged dust can be adsorbed on the dust removal net. Of course, the present invention is not limited to this. The purification body 21 may also include an electrostatic dust removal net or an ion generator, etc.

[0063] According to the fresh air structure 100 of the embodiment of the present invention, a guide plate 22 is set on the purification component 2 in the shell 1, and the airflow entering the shell 1 from the outdoor inlet 13 is guided to the side of the purification body 21 away from the outlet 14, which can better guide the flow of the airflow, make the flow of the airflow smoother, and reduce the flow noise of the airflow. In addition, the airflow entering the shell 1 can also be guided to the side of the purification body 21 away from the outlet 14, so that it flows to the outlet 14 after being purified by the purification body 21, thereby ensuring the cleanliness of the airflow flowing out of the fresh air structure 100 and ensuring the health of the user.

[0064] In some embodiments of the present invention, Figure 5 and Figure 6 As shown, one end of the guide plate 22 connected to the purification body 21 is inclined toward the outdoor inlet 13, thereby guiding the outdoor air entering from the outdoor inlet 13 to the side of the purification body 21 away from the outlet 14, so that all the air entering the shell 1 is filtered by the purification body 21 and then flows out from the outlet 14, ensuring the cleanliness of the air entering the room and ensuring the health of the user.

[0065] Specifically, such as Figure 5 and Figure 6 As shown, combined Figure 1and Figure 2 The outlet 14 is provided on one side of the purification body 21 in a first direction, and the outdoor inlet 13 is provided on one side of the purification body 21 in a second direction. The first direction and the second direction are perpendicular. Along the second direction, the guide plate 22 is located on the side of the purification body 21 close to the outdoor inlet 13. Along the first direction, the guide plate 22 is located on the side of the outdoor inlet 13 close to the outlet 14. Along the second direction and in the direction from the outdoor inlet 13 to the purification body 21, the guide plate 22 is inclined in a direction away from the outlet 14. In this way, the outdoor air entering from the outdoor inlet 13 can be guided to the side of the purification body 21 away from the outlet 14, so that all the air entering the housing 1 is filtered by the purification body 21 and then flows out from the outlet 14, thereby ensuring the cleanliness of the air entering the room and the health of the user.

[0066] Among them, the end of the purification body 21 facing away from the outdoor inlet 13 along the first direction abuts against the shell 1, and the end of the guide plate 22 facing away from the purification body 21 abuts against the shell 1, which can prevent some of the air entering the shell 1 from the outdoor inlet 13 from being discharged from the outlet 14 without being purified.

[0067] In some embodiments of the present invention, Figure 3 and Figure 4 As shown, the fresh air structure 100 also includes a temperature sensing line 3, which is arranged on the side of the guide plate 22 that is away from the outdoor inlet 13 in the thickness direction. The temperature sensing line 3 includes a temperature sensing head 31 and a wire body 32 connected to the temperature sensing head 31. The temperature sensing head 31 can measure temperature, and the wire body 32 is used to connect the temperature sensing head 31 and the electronic control module outside the shell 1, so as to transmit the temperature signal measured by the temperature sensing head 31 to the electronic control module. In the present application, the temperature sensing line 3 is arranged on the side of the guide plate 22 that is away from the outdoor inlet 13, so as to avoid the setting of the temperature sensing line 3 affecting the airflow flowing from the outdoor inlet 13 into the shell 1 along the guide plate 22, so that the airflow flows more smoothly and avoids generating large noise.

[0068] In addition, if Figure 4 As shown, the housing 1 is provided with a wire outlet 15 , and the wire 32 can be led out from the wire outlet 15 to the outside of the housing 1 and connected to the electronic control module, etc.

[0069] Optionally, the temperature sensing line 3 extends along a third direction, and the third direction is perpendicular to the first direction and the second direction. Of course, the present invention is not limited thereto, and the temperature sensing line 3 can also extend along the second direction or other directions.

[0070] like Figure 9 and Figure 10 As shown, reference Figure 7 and Figure 8The guide plate 22 has an opening 221, and the temperature sensing head 31 is arranged opposite to the opening 221. The gas entering the housing 1 from the outdoor inlet 13 can flow to the side of the guide plate 22 away from the outdoor inlet 13 through the opening 221 on the guide plate 22, so that the temperature sensing head 31 comes into contact with the airflow, allowing the temperature sensing head 31 to sense the temperature, thereby detecting the temperature of the gas entering the fresh air structure 100 with high accuracy, thereby achieving accurate measurement of the temperature of the gas entering the housing 1 without affecting the flow of air.

[0071] In addition, by measuring the temperature of the gas entering the fresh air structure 100, the operation of other components can be controlled. For example, in cold winter, the heating temperature of the air conditioner that regulates the indoor temperature can be controlled by obtaining the temperature of the outdoor air entering the room, or the fresh air structure 100 also includes a heat exchange structure, which is used to exchange heat with the air entering the room. By measuring the temperature of the outdoor air entering the fresh air structure 100, the heat exchange capacity of the heat exchange structure can be adjusted, thereby improving the comfort of indoor users.

[0072] In some embodiments of the present invention, Figure 8 and Figure 10 As shown, there are multiple openings 221, spaced apart along the length of the temperature sensor 31. The space between two adjacent openings 221 supports the temperature sensor 31, preventing it from falling into the openings 221 or entering the side of the guide plate 22 facing the outdoor inlet 13 through the openings 221, thereby affecting the airflow. The multiple openings 221 also increase the total area of ​​the openings 221, increasing the ventilation area, allowing the temperature sensor to better contact the airflow, fully detecting the airflow temperature, and achieving more accurate measurement results.

[0073] Further, if Figure 10 As shown, the distance between the surfaces of the two farthest openings 221 is greater than or equal to the length of the temperature sensing head 31. This allows the openings 221 to cover the temperature probe along the length of the temperature sensing head 31, allowing the temperature probe to fully contact the airflow and fully detect the temperature of the airflow, ensuring the accuracy of the measurement results.

[0074] In some embodiments of the present invention, Figure 10 As shown, the opening 221 is a strip-shaped hole extending along the width of the temperature sensing head 31, and the width of the strip-shaped hole is smaller than the length of the temperature sensing head 31. This can increase the area of ​​the opening 221 area, ensure ventilation, enable the temperature sensing head to better contact with the airflow, fully detect the airflow temperature, and make the measurement results more accurate. At the same time, it can prevent the temperature sensing head 31 or the wire body 32 from falling into the opening 221.

[0075] Alternatively, as Figure 10As shown, the opening 221 is an oblong hole extending along the width direction of the temperature sensing head 31. Of course, the present invention is not limited thereto, and the opening 221 can also be a rectangular hole extending along the width direction of the temperature sensing head 31.

[0076] In some embodiments of the present invention, Figure 10 As shown, the dimension of the opening 221 along the width direction of the temperature sensing head 31 is greater than or equal to the maximum width of the temperature sensing head 31. As a result, the opening 221 area can cover the temperature sensing probe in the width direction of the temperature sensing head 31, allowing the temperature sensing probe to fully contact the airflow and fully detect the temperature of the airflow, ensuring the accuracy of the measurement results.

[0077] In some embodiments of the present invention, Figure 10 As shown, a snap assembly 4 is provided on the side of the deflector 22 facing away from the outdoor inlet 13. This snap assembly 4 is used to secure the temperature sensing cable 3 to the deflector 22. This secures the temperature sensing cable 3, preventing it from falling off the deflector 22 and ensuring the reliability of the temperature sensing cable 3 in detecting temperature. Furthermore, the snap assembly 4 has a simple structure, providing a simple and reliable way to secure the temperature sensing cable 3.

[0078] Specifically, such as Figure 10 As shown, the buckle assembly 4 includes a first buckle 41 and a second buckle 42. The first buckle 41 is used to secure the temperature sensing head 31. The second buckle 42 is spaced apart from the first buckle 41 in the longitudinal direction of the temperature sensing cable 3 and is used to secure the cable body 32. Thus, the first buckle 41 and the second buckle 42 respectively secure the temperature sensing head 31 and the cable body 32 to the guide plate 22, thereby improving the fixing effect of the temperature sensing cable 3.

[0079] Further, if Figure 10 As shown, combined Figure 15 The first and second clips 41 and 42 each include a connecting portion 43 and a clamping portion 44. One end of the connecting portion 43 is connected to the guide plate 22, and the other end extends in the thickness direction of the guide plate 22, away from the guide plate 22. One end of the clamping portion 44 is connected to the other end of the connecting portion 43 and is spaced apart from the guide plate 22. The other end extends toward one side of the connecting portion 43 along the width direction of the temperature sensing head 31. A clamping space is defined between the connecting portion 43 and the clamping portion 44, and the temperature sensing head 31 or the wire body 32 is clamped in the clamping space. An opening for installing or removing the temperature sensing head 31 or the wire body 32 is defined between the end of the clamping portion 44 facing away from the connecting portion 43 and the guide plate 22.

[0080] Furthermore, the opening directions of the first and second clips 41, 42 are opposite. When the opening directions of the first and second clips 41, 42 are the same, the temperature sensing head 31 and the cable body 32 are easily dislodged from one side of the opening. Therefore, the opening directions of the first and second clips 41, 42 are opposite, and the first and second clips 41, 42 are respectively limited on opposite sides, which can prevent the temperature sensing head 31 from dislodging from the first clip 41 and prevent the cable body 32 from dislodging from the second clip 42, thereby improving the fixing effect of the temperature sensing head 31 and the cable body 32.

[0081] In some embodiments of the present invention, Figure 10 As shown, the fresh air structure 100 also includes a clamping ring 5, which is sleeved on the wire body 32 and located between the first clamping buckle 41 and the second clamping buckle 42. The clamping ring 5 is suitable for abutting against the side of the second clamping buckle 42 facing the first clamping buckle 41. The clamping ring 5 is located on the wire body 32 on the side of the second clamping buckle 42 facing the first clamping buckle 41. The size of the clamping ring 5 is larger than the size of the clamping space of the second clamping buckle 42, and the internal size of the clamping ring 5 is smaller than the size of the temperature sensing head 31. When the wire body 32 is pulled outward, the clamping ring 5 can be clamped between the temperature sensing head 31 and the second clamping buckle 42 and abut against the second clamping buckle 42, which can prevent the temperature sensing head 31 from being pulled out or the position of the temperature sensing head 31 from being pulled off. The clamping ring 5 can be movably sleeved on the wire body 32, or it can be fixedly sleeved on the wire body 32.

[0082] Furthermore, during design, the position where the clamp ring 5 and the second buckle 42 abut against each other can be the correct position of the temperature sensing head 31. During installation, the operator can pull the wire body 32 toward the wire outlet 15. When the clamp ring 5 and the second buckle 42 abut against each other, the installation position of the temperature sensing head 31 can be confirmed to be accurate, thereby determining the position of the temperature sensing head 31 and ensuring the accuracy of temperature measurement by the temperature sensing head 31.

[0083] In some embodiments of the present invention, Figure 11-13 As shown, the cross section of the temperature sensing head 31 is circular, and the side of the first clip 41 facing the snap-fit ​​space, i.e., the side facing the guide plate 22, has an arcuate groove 411. Specifically, the side of the snap-fit ​​portion 44 facing the snap-fit ​​space, i.e., the side facing the guide plate 22, has an arcuate groove 411. The arcuate groove 411 penetrates the first clip 41 in the length direction of the temperature sensing head 31. The diameter of the arcuate groove 411 can be the same as the diameter of the temperature sensing head 31, and the temperature sensing head 31 is clamped in the arcuate groove 411. This can limit the temperature sensing head 31. In addition, combined with the structure of the snap ring 5, the snap ring 5 can support the wire body 32 and the temperature sensing head 31, so that the temperature sensing head 31 is located in the arcuate groove 411, ensuring that the arcuate groove 411 has a limiting effect on the temperature sensing head 31.

[0084] In some embodiments of the present invention, Figure 10As shown, a limiting rib 6 is further provided on the side of the deflector 22 facing away from the outdoor inlet 13. The limiting rib 6 is located on the side of the second buckle 42 facing away from the first buckle 41, and on the side of the wire 32 that opens toward the second buckle 42. This prevents the wire 32 from slipping out of the opening of the second buckle 42, ensuring that the second buckle 42 secures the wire 32. The limiting rib 6 and the second buckle 42 are spaced apart along the length of the wire 32, which not only facilitates the retention of the wire 32 within the securing space of the second buckle 42, but also serves to limit the wire 32, preventing it from slipping out of the second buckle 42.

[0085] In some embodiments of the present invention, Figure 14-17 As shown, the height of the limiting rib 6 is higher than the height of the limiting space of the second buckle 42. In the width direction of the temperature sensing cable 3, the free end of the limiting rib 6 is located on the side of the opening of the second buckle 42 that faces the interior of the engaging space of the second buckle 42. As a result, the limiting rib 6 can better prevent the temperature sensing cable 3 from escaping from the engaging space in the second buckle 42.

[0086] For example, in Figure 17 In the example shown, the height direction of the limiting rib 6 is the thickness direction of the guide plate 22, and the width direction of the temperature-sensing wire 3 is perpendicular to the length direction of the temperature-sensing wire 3 and parallel to the guide plate 22. The highest point of the limiting rib 6 is A, the opening position of the second clip 42 is B, and the highest point of the engaging space of the second clip 42 is C. The highest point A of the limiting rib 6 is higher than the highest point C of the engaging space of the second clip 42. At the same time, the highest point A of the limiting rib 6 is located on the side of the opening position B of the second clip 42 facing the interior of the engaging space of the second clip 42, that is, the side facing the temperature-sensing wire 3. In a plane perpendicular to the length direction of the temperature-sensing wire 3, the limiting rib 6 and the second clip 42 can enclose a closed space, thereby preventing the temperature-sensing wire 3 in the second clip 42 from falling out.

[0087] Further, if Figure 7 As shown, the free end of the limiting rib 6 is inclined toward one side of the clamping space inside the second buckle 42, thereby better ensuring the fixing effect of the temperature sensing wire 3 and preventing the temperature sensing wire 3 from escaping from the clamping space of the second buckle 42.

The fresh air shell 11 and the first volute half shell 12 are snap-connected and / or connected by fasteners.

[0089] In some embodiments of the present invention, the fresh air structure 100 further includes a fan assembly connected to the housing 1 and configured to drive airflow from the outdoor inlet 13 to the outlet 14. The fan assembly may include a second volute half-shell, a wind wheel, and a motor. The second volute half-shell is located on the side of the first volute half-shell 12 facing away from the fresh air housing 11 and is connected to the first volute half-shell 12 to form a complete volute structure. The wind wheel is disposed within a cavity formed by the first volute half-shell 12 and the second volute half-shell. The outlet 14 serves as an air inlet for the fan assembly, and the air outlet of the fan assembly may be defined by the first volute half-shell 12 and the second volute half-shell. The outlet 14 is located on one side of the wind wheel axial direction.

[0090] Of course, the present invention is not limited to this.

[0093] The air conditioner can be a wall-mounted air conditioner, and the fresh air structure 100 is arranged on the chassis. The fresh air structure 100 is arranged at one end of the air conditioner in the length direction, thereby making the internal layout of the air conditioner more compact and reasonable.

[0094] According to the air conditioner of the embodiment of the present invention, by setting the above-mentioned fresh air structure 100, a guide plate 22 is set on the purification component 2 in the shell 1, and the airflow entering the shell 1 from the outdoor inlet 13 is guided to the side of the purification body 21 away from the outlet 14, which can better guide the flow of the airflow, make the flow of the airflow smoother, and reduce the flow noise of the airflow. In addition, the airflow entering the shell 1 can also be guided to the side of the purification body 21 away from the outlet 14, so that it flows to the outlet 14 after being purified by the purification body 21, thereby ensuring the cleanliness of the airflow flowing out of the fresh air structure 100 and ensuring the health of the user.
