These drawings and descriptions are not intended to limit the scope of the concept in any way, but rather to illustrate the concept of this application to those skilled in the art through reference to particular embodiments. Detailed Implementation

[0045] As mentioned in the background technology, the heating equipment continuously blows hot air into the room. In a closed environment, the heating equipment does not introduce fresh air when it is running, which may lead to an increase in carbon dioxide concentration and a decrease in oxygen content, affecting air quality. The heating equipment may also reduce air humidity during the heating process, resulting in dry air and further aggravating discomfort.

[0046] Therefore, there is an urgent need for a heating device that can solve the problem of poor indoor air circulation.

[0047] In view of this, this application provides a heating and ventilation system (HVAC) that, through the coordinated operation of an external fan and a fresh air fan, achieves better air exchange and significantly improves air exchange efficiency. The HVAC system can effectively introduce fresh outdoor air, reduce indoor carbon dioxide concentration, increase oxygen content, and improve indoor air quality, preventing users from feeling stuffy indoors. The fresh air function brought by the external fan can introduce outside air, improve the air dryness caused by heating, and enhance indoor comfort.

[0048] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.

[0049] The technical solution of this application and how the technical solution of this application solves the above-mentioned technical problems are described in detail below with specific embodiments. These specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments. The embodiments of this application will now be described with reference to the accompanying drawings.

[0050] This application provides a heating, ventilation and air conditioning (HVAC) device, including a main body 100 and an external fan 200.

[0051] The main body 100 includes a housing 110 and a fresh air fan 120. The housing 110 is provided with a first chamber 101. The fresh air fan 120 is disposed in the first chamber 101, and the air outlet side of the fresh air fan 120 faces the outside of the housing 110.

[0052] An external fan 200 is installed in the housing 110, and the external fan 200 is provided with a second chamber 201; the air inlet of the second chamber 201 is connected to the outside of the housing 110, and the air outlet of the second chamber 201 is connected to the first chamber 101, and can discharge air to the air inlet side of the fresh air fan 120.

[0053] refer to Figures 1-3 As can be seen, the housing 110 serves as the external structure of the entire device, housing other functional components such as the internal fresh air fan 120, heating elements, and warm air fans.

[0054] The fresh air fan 120 is installed in the first chamber 101, with its air outlet facing the outside of the housing 110, and is responsible for delivering fresh air into the room. It can be understood that the outside of the housing 110 here refers to the indoor space outside the housing 110.

[0055] The fresh air fan 120 is installed on the wall, and the first chamber 101 is located inside the housing 110. The external fan 200 and the fresh air fan 120 work together to achieve a 2x faster air exchange rate.

[0056] refer to Figure 3 (The arrows indicate the direction of airflow). The external fan 200 introduces outdoor air through the second chamber 201 and works in conjunction with the fresh air fan 120. The fresh air fan 120 then blows the fresh outdoor air into the pool and into the room. Compared to the fresh air fan 120 working alone, the outdoor air has greater kinetic energy entering the room, thus achieving efficient air exchange.

[0057] The air inlet of the second chamber 201 is connected to the outside of the housing 110. This can be understood as the outside of the housing 110 referring to the outdoor environment outside the housing 110, ensuring that fresh air from the outside can be introduced.

[0058] The air outlet of the second chamber 201 is connected to the first chamber 101, so that outdoor air can smoothly enter the air inlet side of the fresh air fan 120, and the air entering the air inlet side of the fresh air fan 120 contains at least outdoor fresh air.

[0059] In some embodiments, the HVAC equipment also includes an exhaust system for exhausting indoor air to the outside, which can cooperate with the fresh air fan 120 and the external fan 200 to maintain indoor air pressure balance.

[0060] In this way, through the coordinated work of the external fan 200 and the fresh air fan 120, the HVAC equipment can achieve better air exchange and significantly improve air exchange efficiency; the HVAC equipment can effectively introduce fresh outdoor air, reduce indoor carbon dioxide concentration, increase oxygen content, and improve indoor air quality, so that users inside do not feel stuffy; the fresh air function brought by the external fan 200 can introduce outside air, improve the air dryness caused by heating, and enhance indoor comfort.

[0061] In some possible implementations, the housing 110 extends along a first direction, and the external fan 200 is disposed at the end of the housing 110 along the first direction.

[0062] It should be noted that the external fan 200 is installed on the wall of the indoor space and is connected to the outdoor space.

[0063] Understandably, the housing 110 extends along the first direction, providing a linear structure that makes the airflow path inside the device clearer and more efficient, helping to optimize airflow and reduce internal air resistance.

[0064] An external fan 200 is located at the end of the housing 110 along the first direction. This position allows the external fan 200 to directly exchange with the outside air, effectively introducing fresh air or exhausting indoor air, enhancing the ventilation and air exchange capacity of the equipment. Moreover, the equipment can form a continuous airflow path in the first direction, ensuring smooth airflow and improving the overall efficiency of the equipment.

[0065] In this way, by placing the external fan 200 at the end of the housing 110 along the first direction, it can exchange air more directly with the external environment, significantly improving the efficiency of fresh air introduction. The extended design of the housing 110 along the first direction makes the internal structure of the equipment more compact, optimizes space utilization, and facilitates installation and maintenance. By placing the external fan 200 at the end of the housing 110, the equipment can more flexibly adapt to different installation environments and usage needs, providing better air quality management.

[0066] In some possible implementations, the external fan 200 is provided with a connecting pipe 300; the first end of the connecting pipe 300 is connected to the air outlet of the second chamber 201, and the second end of the connecting pipe 300 is connected to the air inlet side of the fresh air fan 120 in the first chamber 101.

[0067] It is known that, since there is a certain distance between the external fan 200 and the first chamber 101, the connecting pipe 300 serves as an outdoor air transmission channel.

[0068] The first end of the connecting pipe 300 is connected to the air outlet of the second chamber 201, ensuring that the external fan 200 can deliver outdoor air through the connecting pipe 300.

[0069] The second end of the connecting pipe 300 is connected to the air inlet side of the fresh air fan 120 in the first chamber 101, ensuring that the air delivered by the external fan 200 can directly enter the fresh air fan 120, so that the fresh air fan 120 can deliver this outdoor fresh air into the room.

[0070] Through the design of the connecting pipe 300, the HVAC equipment can form a continuous airflow path from the external fan 200 to the fresh air fan 120, ensuring that outdoor air enters the room efficiently and improving air exchange efficiency; the reasonable airflow path design enables the equipment to deliver air more efficiently and improve overall performance.

[0071] In some possible implementations, the housing 110 is provided with a mounting port 111, which communicates with the first chamber 101.

[0072] The connecting pipe 300 is fitted onto the installation port 111.

[0073] It is known that the mounting port 111 is located on the housing 110 and communicates with the first chamber 101, through which the connecting pipe 300 passes to achieve airflow connection.

[0074] The design of the mounting port 111 and the connecting pipe 300 forms an effective airflow path, ensuring that external air can smoothly enter the first chamber 101, thus improving the air exchange efficiency inside the chamber. The connecting pipe 300 is located inside the housing 110, reducing the impact of the external environment and extending the service life of the equipment.

[0075] In some possible implementations, the external fan 200 is detachably connected to the housing 110.

[0076] Understandably, the connection design between the external fan 200 and the housing 110 facilitates the removal of the external fan 200 from the housing 110 when needed, providing flexibility and ease of maintenance for the equipment.

[0077] Detachable connections can be achieved using bolts, clips, or other quick-connect fittings, ensuring stability during connection and ease of disassembly.

[0078] The detachable connection allows the external fan 200 to be installed or removed as needed, adapting to different usage environments and requirements. When the external fan 200 needs maintenance or replacement, the detachable design makes the process simpler and faster, reducing equipment downtime. Through the flexible connection design, the equipment can better adapt to different installation conditions and space constraints.

[0079] refer to Figure 4 In some possible implementations, the first chamber 101 is provided with a first air inlet 102 and a second air inlet 103, both of which are located on the air intake side of the fresh air fan 120.

[0080] The first air inlet 102 is connected to the air outlet of the second chamber 201, and the second air inlet 103 is connected to the outside of the housing 110.

[0081] It can be understood that in this embodiment, the first air inlet 102 is connected to the air outlet of the second chamber 201, and the air introduced from the external fan 200 can directly enter the first chamber 101. Figure 4 (The direction indicated by the middle arrow 'a').

[0082] The second air inlet 103 is connected to the outside of the housing 110, allowing fresh air to be directly introduced from the external environment. Figure 4 (The direction indicated by the middle arrow b). Then, the fresh air fan 120 exhausts air from the outlet into the room ( Figure 4 (The direction indicated by the middle arrow c).

[0083] With the multi-path air intake design of the first air inlet 102 and the second air inlet 103, the fresh air fan 120 can obtain air from multiple sources, improving the flexibility and efficiency of air flow; through multi-path air intake, the equipment can select a better air introduction path according to the external environmental conditions, improving overall performance.

[0084] In some possible implementations, housing 110 is provided with a ventilation panel 400, which can be directed toward the indoor environment.

[0085] The ventilation panel 400 is provided with a ventilation opening 410, which is connected to the air outlet side of the fresh air fan 120 in the first chamber 101.

[0086] Understandably, the design of the ventilation panel 400 allows the HVAC equipment to face directly into the room, ensuring that heated air can be effectively delivered into the indoor space. The presence of the vent 410 allows outdoor air to enter the room through the ventilation panel 400, forming an effective airflow path.

[0087] Understandably, vent 410 is not only the outlet for fresh air, but also the outlet for hot air from HVAC equipment.

[0088] By setting vents 410 on the ventilation panel 400, the device can form a direct airflow path from the heating element to the room, reducing airflow resistance, reducing heat loss, and improving the heating efficiency of the device. Through the optimized airflow path, the device can distribute heated air more evenly, improve indoor airflow, and enhance comfort. The design of the ventilation panel 400 allows the device to more directly affect the indoor environment, improve the user experience, and meet the user's needs for temperature and air quality.

[0089] In some possible implementations, the ventilation panel 400 is provided with a decorative grille 420.

[0090] In some possible implementations, the first chamber 101 is provided with a second air inlet 103;

[0091] The second air inlet 103 is located on the ventilation panel 400 and is connected to the air intake side of the fresh air fan 120 in the first chamber 101.

[0092] It is known that the second air intake 103 is located on the ventilation panel 400, ensuring that air can be drawn directly from the indoor environment.

[0093] The ventilation panel 400 is equipped with a second air inlet, which allows the ventilation panel 400 to be used not only for air output (hot air and fresh air) but also for air intake, increasing the functionality of the equipment. It can also recirculate the heated air in the room before blowing it out, avoiding uneven distribution of hot air in the room.

[0094] Outdoor air is circulated through an external fan 200. Figure 5 Entering the first chamber 101 in the direction indicated by the middle arrow d, along... Figure 5 The air enters the room in the direction indicated by the middle arrow f; indoor air is then introduced through the fresh air fan 120. Figure 5 Entering the first chamber 101 in the direction indicated by the middle arrow e, along... Figure 5 Enter the room in the direction indicated by the middle arrow f.

[0095] The design of the second air inlet 103 ensures a smooth air introduction path and improves the air circulation efficiency of the equipment. By recirculating the heated air, the equipment can avoid uneven distribution of indoor hot air, improve the uniformity of indoor temperature, and enhance user comfort.

[0096] In some possible implementations, the main body 100 is provided with an odor detection device.

[0097] Understandably, the odor detection device is used to monitor odor components in indoor air and provide real-time air quality feedback. The housing 110, as the external structure of the device, provides space for installing the odor detection device, enabling it to effectively monitor air quality.

[0098] With the use of the odor detection device, the fresh air fan 120 and the external fan 200 can be selectively turned on to introduce fresh outdoor air in time when the indoor air quality is poor or there is an odor, so as to keep the indoor air fresh.

[0099] Odor detection device 400 can be directly linked to the operation of fan 120 and external fan 200, or the odor detection device 400 can remind users to turn on the fresh air function of HVAC equipment in time through alarm signals (such as light display, sound warning, etc.).

[0100] In some embodiments, the housing 110 is provided with a detection port facing downwards.

[0101] The detection port on the housing 110 faces downwards to ensure that the odor detection device can come into contact with the air flowing through the vent 140.

[0102] By ensuring that the odor detection device can come into contact with the air flowing through the vent 410, the odor detection device will monitor indoor air quality more accurately, helping users to determine in a timely manner whether to activate the fresh air exchange function.
