Next, referring to the accompanying drawings, the fresh air component 100 according to the embodiment of the present invention will be described.

As shown in Figures 1-4, the fresh air component 100 has a fresh air outlet 11, an indoor air inlet 12 and an indoor air outlet 13. connected. 5-8, the fresh air component 100 includes a fan assembly 2, the inlet 21 of the fan assembly is suitable for taking in air from at least one of the fresh air inlet 11 and the indoor air inlet 12, and the outlet 22 of the fan assembly is suitable for entering from the fresh air outlet 11 and the indoor outlet. At least one of the tuyeres 13 is exhausted.

It should be noted that the number of fresh air outlets 11 is not limited, for example, it may be one, so as to switch communication with one of the inlet 21 of the fan assembly and the outlet 22 of the fan assembly. For another example, the number of fresh air outlets 11 can be more than one, for example, there can be at least two, at least one is used to communicate with the inlet 21 of the fan assembly, and the remaining at least one is used to communicate with the outlet 22 of the fan assembly.

6-7, the fresh air component 100 includes a ventilation switching assembly 3, a first processing assembly 4 and a second processing assembly 5, the first processing assembly 4 is arranged on the airflow path from the fresh air outlet 11 to the inlet 21 of the fan assembly , the second processing assembly 5 is arranged on the airflow path from the indoor air inlet 12 to the inlet 21 of the fan assembly. The ventilation switch assembly 3 is used to control the air flow connection state, so that the fresh air component 100 can switch at least three states of the first state, the second state and the third state.

It should be noted that "suitable for ... exhaust" and "suitable for ... air intake" herein mean that the airflow path at the corresponding position is not blocked by the ventilation switching assembly 3 When it is in a ventilated state, only the "normally connected" in special instructions means that the ventilating switch assembly 3 cannot be blocked and is in a ventilated state all the time. In addition, it should be noted that the "suitable for intake from a certain place" mentioned in this article is understood in a broad sense, including direct intake from a certain place and indirect intake from a certain place. The "suitable for exhausting from a certain place" mentioned in this article is understood in a broad sense, including both direct exhausting from a certain place and indirect exhausting from a certain place.

As shown in FIG. 9 , in the first state, the fan assembly 2 takes in air through the fresh air outlet 11 and exhausts it through the indoor air outlet 13 . Thus, when it is necessary to introduce fresh air from the outside to the room, the ventilation switching assembly 3 can be used to switch the fresh air component 100 to the first state, so that when the fan assembly 2 is working, the outdoor air can enter the fresh air component 100 through the fresh air port 11, and be drawn into the fresh air component 100. The first processing component 4 processes it, and then sends it into the room through the indoor air outlet 13, thereby improving the feeling of stuffiness in the room.

It should be noted that the specific composition of the first processing assembly 4 is not limited, for example, it may include at least one of a dust removal and purification module, a sterilization and purification module, a heating module, and a humidification module. The fresh air introduced meets the indoor environment requirements. In addition, it should be noted that when the first processing component 4 includes multiple modules, in some specific examples, at least one module can be selected to work according to needs, for example, several modules can work, and at the same time, the rest of the modules do not work , in some specific examples, at least one module can be selected to be installed according to needs, for example, several modules can be installed, and the remaining modules can not be installed, for example, the number of modules is more than the number of installation positions, and the installation positions can replace several modules.

As shown in Figure 10, in the second state, the fan assembly 2 takes in air through the indoor air inlet 12, and exhausts air through the indoor air outlet 13, thus, when the indoor air needs to be processed, the ventilation switching assembly 3 can be used Switch the fresh air component 100 to the second state, so that when the fan assembly 2 is working, indoor air can enter the fresh air component 100 through the indoor air inlet 12, be processed by the second processing assembly 5, and then be sent back to the room through the indoor air outlet 13, improving Indoor air quality.

It should be noted that the specific composition of the second processing assembly 5 is not limited, for example, it may include at least one of a dust removal and purification module, a sterilization and purification module, a heating module, and a humidification module. By setting the second processing assembly 5, the treated air Meet the needs of indoor environment. In addition, it should be noted that when the second processing component 5 includes multiple modules, in some specific examples, at least one module can be selected to work according to needs, for example, several modules can work, while the rest of the modules do not work , in some specific examples, at least one module can be selected to be installed according to needs, for example, several modules can be installed, and the remaining modules can not be installed, for example, the number of modules is more than the number of installation positions, and the installation positions can replace several modules.

As shown in FIG. 11 , in the third state, the fan assembly 2 takes in air through the indoor air inlet 12 and exhausts through the fresh air outlet 11 . Thus, when it is necessary to discharge indoor air to the outside, the ventilation switching assembly 3 can be used to switch the fresh air component 100 to the third state, so that when the fan assembly 2 is working, the indoor air can enter the fresh air component 100 through the indoor air inlet 12 and be released. The second processing component 5 processes, and then discharges to the outside through the fresh air outlet 11, so as to achieve the effect of exhausting the air from the room to the outside. In addition, because the exhaust air is processed by the second processing component 5, it can protect the outdoor environment to a certain extent, and has better environmental protection.

Therefore, according to the fresh air component 100 of the embodiment of the present invention, various states can be switched to meet different actual use requirements. Moreover, the airflow path is simple, the wind resistance is small, and the noise effect is low. In addition, by arranging the first processing assembly 4 and the second processing assembly 5 on two different air inlet paths, the two processing assemblies can be separately designed according to the source of the air to be processed, and the first processing assembly 4 and the second processing assembly The two processing components 5 are set to be the same or different, so as to give consideration to economy and processing effect. For example, the first processing assembly 4 is used to process the fresh air introduced from outside to the room. Since the outdoor air may have more dust than the indoor air, the dust removal ability of the first processing assembly 4 needs to be higher than that of the second processing assembly 5. The second processing assembly 5 is used to process the air discharged from the indoor to the indoor or outdoor. Since the indoor air may have a heavier odor or more bacteria than the outdoor air, the second processing assembly 5 can deodorize relative to the first processing assembly 4. Or the bactericidal ability needs to be stronger.

As shown in Figures 12 and 13, the fan assembly 2 can include an air duct casing 23 and a fan 24, the air duct casing 23 defines a volute cavity 231, the fan 24 includes a wind wheel 241 and a motor 242, and the wind wheel 241 is arranged on the volute The cavity 231, the motor 242 is connected with the wind wheel 241 and drives the wind wheel 241 to rotate.

2 and 3, the entrance of the volute chamber 231 is suitable for intake air from at least one of the fresh air inlet 11 and the indoor air inlet 12, so that in the first state, referring to FIG. 11 to introduce airflow. In the second state and the third state, referring to FIG. 10 and FIG. 11 , the inlet of the volute cavity 231 can introduce airflow from the indoor air inlet 12 .

As shown in Figure 8, the air duct shell 23 defines an air outlet channel 232 and an air exhaust channel 233, and the inlet of the air outlet channel 232 communicates with the outlet of the volute cavity 231, so that the airflow of the volute cavity 231 can be discharged into the air outlet channel 232. It should be noted that the communication between the inlet of the air outlet channel 232 and the outlet of the volute cavity 231 may be in a normally connected state to simplify the structure.

9 and 10, the outlet of the air outlet channel 232 is suitable for exhausting through the indoor air outlet 13. It should be noted that the number of air outlet channels 232 provided by the fresh air component 100 as a whole is not limited, as long as there is at least one air outlet channel At least part of 232 can be exhausted through the indoor air outlet 13 in a corresponding mode. Thus, in the first state and the second state, the airflow discharged into the corresponding air outlet channel 232 can be sent to the room through the indoor air outlet 13 .

As shown in Fig. 8 and Fig. 11, there is a communication port 234 on the side wall of the air outlet channel 232, the air outlet channel 232 is suitable for exhausting air to the exhaust channel 233 through the communication port 234, and the exhaust channel 233 is suitable for passing through the fresh air port 11 Exhaust outward. It should be noted that the number of exhaust channels 233 provided by the fresh air component 100 as a whole is not limited, as long as at least one air outlet channel 232 can be exhausted from the fresh air port 11 through the exhaust channel 233 in a corresponding mode. That's it. Thus, in the third state, the airflow discharged into the corresponding air outlet channel 232 can enter the exhaust channel 233 through the communication port 234 , and then be discharged to the outside from the fresh air port 11 .

Thus, since the air duct housing 23 is formed with a volute cavity 231, an air outlet channel 232 communicating with the volute cavity 231, and an exhaust channel 233 suitable for communicating with the air outlet channel 232, the air flow path can be simplified and the air flow can be facilitated. The integrated design and processing of the path improves the airtightness of the airflow path, and the integration and modularization are strong.

As shown in FIG. 13 , in some embodiments, there are two air duct shells 23 which are set independently of each other, and at least one wind wheel 241 is arranged in each air duct shell 23 . The wind wheels 241 in each air duct shell 23 can be connected to the motors 242 respectively, so as to be driven by separate motors 242, or the wind wheels 241 in each air duct shell 23 can also be jointly driven by the same motor 242, thereby saving the number of motors 242 , and improve the compactness of the structure. Thus, when the wind wheels 241 in the two air duct shells 23 are all working, a larger ventilation rate can be ensured to meet the working effect of a large ventilation rate and improve the air treatment efficiency, such as speeding up the indoor air flow and improving the comfort of the human body. feel. And when the wind wheel 241 in one of the air duct shells 23 works, it can meet the requirements of the single air duct shell 23 for air outlet and reduce energy consumption. When the on-off status of 233 is inconsistent, it is also possible to control the operation of the wind wheel 241 corresponding to the air duct shell 23 to present different wind-out effects.

As shown in Fig. 13, when there are two air duct shells 23 and they are arranged independently of each other, in some optional examples, at least one wind wheel 241 is arranged in each air duct shell 23, and there is one motor 242 and is arranged on two air duct shells. Between the two air duct shells 23, and connected with the two wind wheels 241 respectively. Therefore, the structure is relatively compact, the cost is low, and the assembly efficiency is high. The two wind wheels 241 can work at the same time, and the ventilation volume is relatively large. Or, in some other optional examples, as shown in FIG. 23 , at least one wind wheel 241 is arranged in each air duct shell 23, and there are two motors 242, which are respectively arranged on one side of the two air duct shells 23 away from each other. On the side, the two motors 242 are respectively connected to the two wind wheels 241 correspondingly. Therefore, by controlling the two motors 242 separately, the two wind wheels 241 can work independently, so as to meet the requirement that the two air duct shells 23 can achieve different wind output effects and/or different wind output at the same time.

Referring to FIG. 8 , the ventilation switching assembly 3 may include a first switching valve 31 disposed at at least one communication port 234 of the duct casing 23 , that is, the ventilation switching assembly 3 includes a first switching valve 31 , at least one communication port 234 A first on-off valve 31 is arranged at the place, and the first on-off valve 31 is used to control the switching situation at the communication port 234. When the first on-off valve 31 opens the communication port 234, the airflow of the air outlet channel 232 can be discharged into the air through the communication port 234. exhaust channel 233 , and when the first switch valve 31 closes the communication port 234 , the airflow in the air outlet channel 232 can no longer enter the exhaust channel 233 through the communication port 234 . Thus, by selecting the number of first on-off valves 31 provided and by controlling the on-off state of each first on-off valve 31 , different air outlet effects can be switched.

It should be noted that the specific structure of the air duct shell 23 is not limited, for example as shown in Figure 14-Figure 16, each air duct shell 23 can include: a volute part 235 and a fixed seat part 236, two fixed seat parts 236 Located between the two volute parts 235, the fan 24 includes two wind wheels 241 and a motor 242, the motor 242 is a biaxial motor 242, each wind wheel 241 is a centrifugal wind wheel 241, two air duct shells 23 are arranged along the left and right direction, the motor 242 is installed between the two volute parts 235 , and a wind wheel 241 is arranged between each volute part 235 and the fixed seat part 236 . Each volute part 235 is formed with the entrance of the volute cavity 231, and the volute part 235 and the fixed seat part 236 in one air duct casing 23 can be connected by fasteners or buckles, so that the wind wheel 241 can be reliably protected , the fixing seat portions 236 of the two duct shells 23 can be connected by fasteners, so that the motor 242 can be reliably installed.

As shown in Figure 22, regardless of the number of duct casings 23, at least one duct casing 23 defines a volute cavity 231, an air outlet channel 232 and two exhaust channels 233, and the two exhaust channels 233 They are respectively arranged on opposite sides of the air outlet channel 232, and at least one exhaust channel 233 is communicated with the air outlet channel 232 through the communication port 234 on the side wall of the air outlet channel 232, and the ventilation switching assembly 3 includes at least one communication port 234 The first switch valve 31. For example, the left and right side walls of the air outlet channel 232 are respectively provided with a communication port 234, and the left and right sides of the air outlet channel 232 are respectively provided with an exhaust channel 233. The air outlet channel 232 communicates, and the exhaust air channel 233 on the right communicates with the air outlet channel 232 through the communication port 234 on the right side, and at least one of the communication port 234 on the left side and the communication port 234 on the right side is provided with a first switch Valve 31.

Thus, by providing two exhaust passages 233, when the on-off conditions of the air outlet passage 232 and the exhaust passages 233 on both sides are inconsistent, different air outlet effects can be presented; When the on-off conditions of the exhaust passage 233 are consistent, the requirement for a large ventilation volume can be met.

It should be noted that, in the above-mentioned embodiments, the location and quantity of the inlets of the volute cavity 231 on the air duct casing 23 can be determined according to the quantity and type of the wind wheels 241, for example, when the volute cavity 231 is provided with When there are two centrifugal wind wheels 241, or double-suction centrifugal wind wheels 241, the inlets of the volute cavity 231 can be two and arranged opposite to each other along the axial direction of the wind wheels 241.
