Description

Technical Field

[0001] The present invention relates to the technical field of fresh air systems, and in particular to an indoor fresh air system. Background Art

[0002] The fresh air system is an electromechanical system used to improve indoor air quality. It introduces fresh air from the outside into the room through mechanical means and exhausts the dirty air from the room to the outside, thereby achieving the circulation and replacement of indoor and outdoor air. The existing fresh air systems are mainly divided into the following three categories: one-way fresh air system, two-way fresh air system and full heat exchange fresh air system.

[0003] In the prior art, the one-way fresh air system only discharges the indoor dirty air through the fan, and the outdoor fresh air is replenished into the room under the action of the air pressure difference. This method does not take into account the temperature of the outdoor air, which may cause large fluctuations in the indoor temperature, especially in cold or hot seasons, which will affect the indoor comfort. In order to achieve the discharge and replenishment of air, the system usually needs to punch holes in the wall, which not only destroys the wall structure, but also may increase the installation cost and complexity. Although the two-way flow system realizes the exchange of indoor and outdoor air at the same time, the system requires two sets of pipes, which increases the complexity and cost of installation, especially when installed in existing buildings, more modifications and punching may be required. Although the two-way flow system has a better ventilation effect, during the air exchange process, the indoor heat will be lost with the exhaust air, which is not conducive to energy saving. The full heat exchange fresh air system adds a heat exchange function on the basis of the two-way flow. Although it can recover heat, the cost of the system is relatively high, including equipment cost and installation cost. The installation of the full heat exchange system is usually more complicated, requiring a larger space and more punching, which may have a certain impact on the building structure. Therefore, the existing fresh air system has certain defects in temperature control, installation complexity and cost that need to be improved. Summary of the invention

[0018] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0019] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection, a direct connection, or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0020] In the present invention, it is also necessary to explain that the directional terms such as one side, one end, the other end, top and bottom in the embodiments of the present application are only relative concepts or are based on the normal use status of the product, and should not be considered as restrictive.

[0021] like Figure 1 and Figure 2As shown, the embodiment of the present application provides an indoor fresh air system for circulating the air of the first indoor space to the second indoor space and circulating the air of the second space internally, including: a first air supply mechanism 1, a second air supply mechanism 2 and a connecting component 3, a door body 4 is arranged between the first indoor space and the second indoor space, the first air supply mechanism 1 is arranged on the side of the door body 4 close to the first space, the second air supply mechanism 2 is arranged on the side of the door body 4 close to the second space, a gap for the connecting component 3 to pass through is arranged between the door body 4 and the ground, one end of the connecting component 3 is connected to the first air supply mechanism 1, and the other end of the connecting component 3 is connected to the second air supply mechanism 2; the first air supply mechanism 1 is used to send the air of the first indoor space to the second space through the connecting component 3; the second air supply mechanism 2 is used to circulate the air of the second space and then send it to the second space. In this embodiment, the first air supply mechanism 1 has the function of air processing and air supply. It is located on the side of the door body 4 close to the first space, responsible for extracting the air of the first space and pushing it to the second space through the connecting component 3. Such a setting can effectively transport the air in the first space (such as the air in the living room) to the second space (such as the bedroom) to achieve air circulation. For example, if there is fresh air or warmer air in the living room, the air can be transported to the bedroom through the first air supply mechanism 1 to improve the air quality or temperature of the bedroom. The second air supply mechanism 2 also has air processing and air supply functions. It is located on the side of the door body 4 close to the second space. It is responsible for extracting air from the second space and sending it back to the second space after processing (such as filtering or disinfection). This setting can recycle the air in the second space and process it at the same time to maintain or improve the air quality. If the air in the bedroom needs to be filtered or the temperature needs to be adjusted, the second air supply mechanism 2 can complete this task without introducing outdoor air. The connecting component 3 (such as a pipe or a hose) is used to connect the first air supply mechanism 1 and the second air supply mechanism 2 to form an air circulation channel. The connecting component 3 allows air to flow between the two spaces without drilling holes in the wall. Through the gap under the door body 4, the connecting component 3 can easily pass through, thereby connecting the two air supply mechanisms to achieve air circulation. The air supply mechanism is set on the door body 4, and the door body 4 is used as the base point for installation. This setting method reduces the complexity of installation and damage to the building structure. Compared with drilling holes in the wall to install pipes, the air supply mechanism on the door body 4 only needs to be simply fixed on the door without damaging the wall. A gap is reserved between the door body 4 and the ground for the connection component 3 to pass through. This design avoids drilling holes in the door body 4, maintains the integrity of the door body 4, and is also easy to install and maintain. If it is necessary to establish air circulation between the living room and the bedroom, the connection component 3 can pass through the gap under the door without modifying the door body 4.

[0022] Specifically, the fresh air system cleverly realizes air circulation between two indoor spaces by arranging an air supply mechanism and a connecting component 3 on the door body 4. This design not only avoids the wall modification required for the traditional fresh air system, but also provides a more energy-saving and comfortable indoor air circulation method. By sending the air from the first space to the second space and performing air circulation treatment inside the second space, the system effectively improves the indoor air quality while maintaining the stability of the indoor temperature. The air in the first space is more stable than the outdoor air temperature, especially in the case of air conditioning or heating, the temperature of the indoor first space is usually more suitable. Therefore, guiding the air from the first space (such as the living room) to the second space (such as the bedroom) can avoid the influence of too low or too high outside temperature, and help the space where the fresh air is sent to maintain a suitable temperature environment. It can filter PM2.5 tiny suspended particles such as dust in the room while disinfecting and sterilizing.

[0023] like Figure 4As shown, further, the first air supply mechanism 1 includes an external unit body 10, a first fan 11 and a first filter assembly 12, the external unit body 10 is arranged on the side of the door body 4 close to the first space, the first fan 11 is arranged on the external unit body 10, and the first filter assembly 12 is arranged on the first fan 11; when the first fan 11 is driven, the air in the first space enters the external unit body 10 from the first filter assembly 12, and the filtered air is then sent to the connecting assembly 3 through the first fan 11. In this embodiment, the external unit body 10 is the main part of the first air supply mechanism 1, which provides a frame for installing and protecting the fan and the filter assembly. It is located on the side of the door body 4 close to the first space, which is convenient for directly extracting air from the first space. The setting of the external unit body 10 makes the entire air supply mechanism more stable, and it is also convenient for maintaining and replacing components. For example, the external unit body 10 can be fixed on one side of the door between the living room and the bedroom as a bracket for the fan and the filter assembly. The first fan 11 is a key component for driving air flow. It generates airflow by rotation and pumps air from the first space to the second space. It is set on the external machine body 10 to ensure the correct connection between the fan and the air inlet (first filter component 12) and the outlet (connection component 3). The setting of the fan realizes the effective circulation of air and is the power source for the operation of the system. When the living room needs to transport air to the bedroom, the fan starts to generate enough airflow to push the air to the connection component 3. The first filter component 12 is used to purify the air, remove dust, pollen and other particulate matter, and improve the air quality. Located on the first fan 11, an air inlet located at the fan can be set to ensure that all air entering the external machine body 10 is filtered. The setting of the filter component ensures that the air sent to the second space is clean, which helps to maintain the indoor air quality. If there is dust in the living room, the first filter component 12 can filter it out before the air is pumped by the fan to prevent dust from entering the bedroom. When the first fan 11 is driven, the air in the first space first passes through the first filter assembly 12, where impurities in the air are removed and purified. A HEPA air filter element can be used to filter particles above PM2.5. The purified air then enters the external unit body 10, and the airflow generated by the first fan 11 is pushed to the connecting assembly 3, and finally sent to the second space. The advantage of this setting is that it not only realizes the circulation of air, but also ensures that the circulating air is purified. In this way, even if the air quality in the first space is not good, the second space can also get fresh air. With this design, the fresh air system can provide additional air purification function while ensuring indoor air circulation, thereby improving the overall performance of the system and the comfort of the living environment.

[0024] like Figure 5As shown, further, the second air supply mechanism 2 includes an inner machine body 20, a negative ion component 21 and an air circulation component, the inner machine body 20 is arranged on the side of the door body 4 close to the second space, and the negative ion component 21 and the air circulation component are respectively arranged on the inner machine body 20; the negative ion component 21 is used to receive the air of the connection component 3 to add negative ions, and then send the air with added negative ions to the second space; the air circulation component is used to inhale the air in the second space for treatment and recirculation to the second space. In this embodiment, the inner machine body 20 is the basic structure of the second air supply mechanism 2, providing an installation position for the negative ion component 21 and the air circulation component. It is located on the side of the door body 4 close to the second space, which is convenient for sending the treated air into the second space. The setting of the inner machine body 20 makes the second air supply mechanism 2 more stable, and it is also convenient for maintenance and replacement of components. For example, the inner machine body 20 can be installed on one side of the bedroom door as a bracket for the negative ion component 21 and the air circulation component. The negative ion component 21 generates negative ions by ionizing air molecules, and these negative ions can absorb dust and other pollutants in the air, thereby purifying the air. It is arranged on the inner machine body 20, located at the outlet of the air outlet position of the connecting component 3, to ensure that the air from the first space is added with negative ions before entering the second space. The setting of the negative ion component 21 further improves the cleanliness of the air sent to the second space, which helps to improve the indoor air quality. If the air sent from the living room has been preliminarily filtered, the negative ion component 21 can further purify the air on this basis to make it fresher. The air circulation component is responsible for inhaling the air in the second space, processing it (such as filtering it again), and then sending it back to the second space. It is also arranged on the inner machine body 20, and can be connected in parallel or in series with the negative ion component 21 to achieve continuous treatment of the air. The setting of the air circulation component realizes the internal circulation of the air in the second space and maintains the stability of the indoor environment. When the air is sent from the first space to the second space through the connecting component 3, it first passes through the negative ion component 21, and the pollutants in the air are adsorbed by the negative ions, and the air is further purified. Subsequently, the air circulation component inhales the air to which the negative ions have been added, filters and circulates it again as needed, and then sends it back to the second space. Not only does it provide air circulation and purification, but it also achieves indoor air conditioning through the air circulation component, thereby improving the comfort of living. For example, the series arrangement of the negative ion component 21 and the air circulation component can ensure that the air undergoes multiple treatments before entering the second space, thereby maximizing the air quality.

[0025] like Figure 6As shown, further, the second air supply mechanism 2 also includes a disinfection component, which is arranged on the inner machine body 20 and is used to disinfect the air in the second space. The disinfection component includes a disinfection lamp 24 and a sensor 25, which are respectively arranged on the inner machine body 20; when the sensor 25 senses that the human body is within a preset range, the disinfection lamp 24 is controlled to stop working. In this embodiment, the disinfection component is used to disinfect the air in the second space, usually by ultraviolet disinfection lamps 24 and other means to kill bacteria and viruses in the air. It is arranged on the inner machine body 20, before or after the air circulation component, to ensure that the air is disinfected before being sent to the second space or during the circulation process. The addition of the disinfection component further improves the sanitation standard of indoor air, reduces pathogens in the air, and protects the health of residents. For example, during the flu season, the disinfection component can effectively reduce the number of viruses in the air and reduce the risk of infection. The disinfection lamp 24 is arranged on the inner machine body 20, and can be arranged to be aligned with the air flow path to ensure that ultraviolet rays can effectively irradiate the air flowing through. The disinfection lamp 24 can continuously disinfect the air and improve the indoor air quality. If there are pets or children at home, the disinfection lamp 24 can help reduce the spread of bacteria on pet dander or children's toys. The sensor 25 is used to detect the presence of the human body. When the human body enters the preset sensing range, the sensor 25 will send a signal. It is set on the inner machine body 20 and linked with the disinfection lamp 24. It is usually located near the disinfection lamp 24 or on the air flow path. The setting of the sensor 25 ensures that the disinfection lamp 24 can automatically stop working when someone is present to prevent ultraviolet rays from causing harm to the human body. If a child approaches the disinfection lamp 24 while playing in the bedroom, the sensor 25 will detect the presence of the child and automatically turn off the disinfection lamp 24 to protect the child from ultraviolet radiation. When the air in the second space is sucked into the inner machine body 20, it will first pass through the disinfection component. The disinfection lamp 24 works when the sensor 25 does not detect the human body and disinfects the air. Once the sensor 25 detects that the human body is within the preset range, it will control the disinfection lamp 24 to stop working to avoid causing harm to the human body. The advantage of this arrangement is that it not only provides a continuous air disinfection function, but also ensures safety of use through the intelligent control of the sensor 25. The disinfection lamp 24 can automatically work when no one is around, and automatically shut down when someone is around, realizing intelligent air quality management. The disinfection component can effectively disinfect the air without hindering the activities of the residents. For example, placing the sensor 25 near the disinfection lamp 24 can ensure that the disinfection lamp 24 stops working immediately once someone approaches.

[0026] like Figure 6As shown, further, the air circulation component includes a second filter component 22 and a second fan 23, the second filter component 22 and the second fan 23 are respectively arranged on the inner machine body 20, when the second fan 23 is driven, the air of the second space enters the inner machine body 20 from the second filter component 22, and the filtered air is then sent to the second space through the second fan 23. The second filter component 22 includes a filter element 220 and a mounting member 221, the filter element 220 is arranged on the inner machine body 20, and the mounting member 221 is arranged on the filter element 220. In this embodiment, the air circulation component is responsible for inhaling, filtering and re-sending air inside the second space to maintain the cleanliness and circulation of indoor air. It is arranged on the inner machine body 20, after the disinfection component, to ensure that the air is filtered before being sent to the second space. The setting of the air circulation component can continuously improve the air quality of the second space and reduce dust and pollutants. For example, in a bedroom, the air circulation component can filter out pollen and dust to provide a cleaner air environment for sleep. The second filter assembly 22 is used to capture and remove particulate matter in the air, such as dust, pollen, pet dander, etc. It is located on the inner machine body 20 and is the first checkpoint for air to enter the inner machine body 20. The second filter assembly 22 can improve the cleanliness of the air and protect the respiratory health of the occupants. If there are people with allergies in the family, the second filter assembly 22 can effectively reduce the number of allergens. The second fan 23 is used to inhale the air in the second space and return the filtered air to the second space by pressure. It is arranged after the second filter assembly 22 and is responsible for pushing the filtered air into the room. The second fan 23 ensures the continuity and efficiency of air circulation and maintains the circulation of indoor air. In winter, the second fan 23 can help evenly distribute indoor heating and avoid local overcooling. The filter element 220 is the core part of the second filter assembly 22, which captures pollutants in the air through physical interception or adsorption. It is installed on the inner machine body 20 and is the only way for air to enter the fan. The effectiveness of the filter element 220 directly affects the quality of air filtration and is the key to maintaining indoor air quality. The high-quality filter element 220 can capture smaller particles and provide cleaner air. The mounting member 221 is used to fix the filter element 220 so that it is stably located in the inner machine body 20 for easy replacement and maintenance. It is arranged on the filter element 220 and cooperates with the structure of the inner machine body 20. The setting of the mounting member 221 makes the replacement of the filter element 220 simple and quick, and reduces the complexity of maintenance. When the filter element 220 needs to be replaced, the mounting member 221 can be quickly disassembled, making maintenance work more efficient. When the second fan 23 is started, it will inhale the air in the second space. The air first passes through the second filter assembly 22, where the filter element 220 captures pollutants, and then the filtered air is sent back to the second space by the fan. This process is continuously cycled to keep the indoor air clean and fresh.By integrating the second filter assembly 22 and the second fan 23 on the inner unit body 20, the system design is compact and easy to install and operate. At the same time, the arrangement of the filter element 220 and the mounting member 221 makes maintenance more convenient and helps to maintain the long-term efficient operation of the system. Such an arrangement ensures that even in a relatively closed indoor environment, the air in the second space can be effectively circulated and purified, thereby providing a healthy and comfortable living environment for the residents.

[0027] like Figure 2 and Figure 3 As shown, further, an air outlet 5 is also provided on the inner machine body 20, for the first air supply mechanism 1 and the second air supply mechanism 2 to output the processed air to the second space. A control component 6 is also provided on the first air supply mechanism 1. Power supply interfaces 7 are respectively provided on the first air supply mechanism 1 and the second air supply mechanism 2. The fresh air system can not only realize the automatic working mode, but also support the individual control of each function. Users can manually choose to start or stop specific functions (such as air filtration, negative ion addition, air circulation or disinfection) through the control component 6 or the APP interface, or they can choose to let the system work automatically according to the air quality or other environmental parameters.

[0028] In this embodiment, the air outlet 5 is an outlet for air flow, which is used to output the processed air from the air supply mechanism to the second space. It is arranged on the external machine body 10 and is connected to the first air supply mechanism 1 and the second air supply mechanism 2. The setting of the air outlet 5 ensures that the air can flow smoothly from the air supply mechanism to the second space to achieve air circulation. For example, in winter, the air outlet 5 can send air from the living room into the bedroom to keep the room warm. The control component 6 is used to adjust and manage the working state of the first air supply mechanism 1, such as wind speed, timer switch, etc. It is arranged on the first air supply mechanism 1 for easy operation and monitoring. The control component 6 allows the user to adjust the working mode of the air supply mechanism according to their needs, thereby improving the flexibility and user experience of the system. The user can set the control component 6 to automatically reduce the wind speed at night to reduce noise and save energy. The power supply interface 7 provides power supply for the first air supply mechanism 1 and the second air supply mechanism 2, and is the power source for the operation of the system. It is respectively arranged on the first air supply mechanism 1 and the second air supply mechanism 2, and can be arranged on the back or side of the device. The air outlet 5 can effectively deliver the air processed by the first air supply mechanism 1 and the second air supply mechanism 2 to the second space, ensuring smooth air circulation. The addition of the control component 6 enables the user to conveniently control the working state of the first air supply mechanism 1, and can adjust the air supply volume according to changes in the indoor and outdoor environment and personal preferences, thereby improving the intelligence and humanization of the system. The existence of the power supply interface 7 is the basis for the operation of the device. By respectively providing the power supply interface 7 on the first air supply mechanism 1 and the second air supply mechanism 2, the system can independently or simultaneously supply power to the two mechanisms, thereby ensuring the independence and reliability of the system. Such a design comprehensively considers the functionality, operation convenience and user needs of the system, so that the entire indoor fresh air system can not only effectively improve the indoor air quality, but also provide a good user experience. It is worth mentioning that the air is first sucked in from the first space (for example, the living room). The suction point is located on the outer machine body 10, close to the side of the first space, where the first fan 11 and the first filter assembly 12 are installed. The air passes through the first filter assembly 12, which is located in the outer machine body 10 and is used to filter out dust and impurities in the air. The filtered air is driven by the first fan 11 and pushed to the second space through the connecting component 3 (such as a pipe or hose). The connecting component 3 passes through the gap at the bottom or side of the door body 4. After the air from the connecting component 3 enters the inner machine body 20, it first passes through the negative ion component 21, which adds negative ions to the air to further purify the air, and then the air is sent to the second space from the air outlet 5 to achieve external circulation. In the second space, the air passes through the disinfection component (if the sensor 25 does not detect the human body, the disinfection lamp 24 will work) to kill bacteria and viruses in the air. Then, the air passes through the second filter component 22, which includes a filter element 220 and a mounting member 221, which is used to further filter fine particles in the air. Finally, the air is driven by the second fan 23 and sent to the second space.The second fan 23 delivers the processed air into the second space to realize the internal circulation of the air in the second space. The air outlet 5 is located on the inner machine body 20 and is the outlet for the air to flow out to the second space.

[0029] By adopting the above-mentioned technical solutions, in the present invention, the fresh air system cleverly realizes the air circulation between the two indoor spaces by arranging the air supply mechanism and the connecting component 3 on the door body 4. This design not only avoids the wall modification required by the traditional fresh air system, but also provides a more energy-saving and comfortable indoor air circulation method. By sending the air from the first space to the second space and performing air circulation treatment inside the second space, the system effectively improves the indoor air quality while maintaining the stability of the indoor temperature. The air in the first space is more stable than the outdoor air temperature, especially in the case of air conditioning or heating, the temperature of the indoor first space is usually more suitable. Therefore, guiding the air from the first space (such as the living room) to the second space (such as the bedroom) can avoid the influence of too low or too high outside temperature, and help the space where the fresh air is sent to maintain a suitable temperature environment.

[0030] The above are only preferred embodiments of the present invention, and are not intended to limit the patent scope of the present invention.
