Description

[0001] This application claims priority to Chinese patent application No. 2024221364308, filed on August 30, 2024, the entire contents of which are incorporated herein by reference. Technical Field

[0002] This application belongs to the field of electrical technology, specifically relating to a fresh air module and an air conditioner. Background Technology

[0003] Fresh air modules are an important component of modern building ventilation systems. Their main function is to introduce fresh outdoor air into the room while expelling stale indoor air to maintain a fresh and comfortable indoor environment. To achieve air circulation, fresh air modules include fan components.

[0004] In the existing technology, the fan assembly consists of an upper volute and a lower volute. After the upper volute is connected to the lower volute, it is installed on the base plate. However, in order to prevent condensation, thermal insulation sponge is placed between the lower volute and the base plate, which makes the operation cumbersome and the installation efficiency low. Utility Model Content

[0005] To address the aforementioned technical problems, this utility model provides a fresh air module and an air conditioner, aiming to at least partially solve the technical problems of cumbersome installation and low installation efficiency of the volute housing of the fresh air module.

[0006] The technical solution of this utility model is as follows:

[0007] A fresh air module is characterized by comprising: a base plate; an insulation component disposed on the base plate; and a volute that contacts the insulation component to form an air duct.

[0008] Because the insulation component is located on the base plate, it can be supported by the base plate. Since the volute and the insulation component are in contact to form an air duct, the insulation component can also be part of the air duct, allowing air to flow smoothly through it. In other words, the traditional lower volute structure is unnecessary, simplifying the product structure, reducing material usage and manufacturing costs. The volute can be placed directly on the insulation component, and the air duct is formed simply by the contact between the volute and the insulation component. This makes the assembly process quick and efficient, reduces installation difficulty and steps, and improves production efficiency. Moreover, since the insulation component can be part of the air duct, the air entering the air duct will not come into contact with the base plate, effectively isolating the base plate from the impact of low outdoor temperatures, reducing condensation, achieving base plate insulation, and improving the user experience.

[0009] In some embodiments, the volute has an air inlet and an opening opposite to the air inlet; wherein the insulation element closes the opening to form the air duct.

[0010] In some implementations, the volute has a first air vent, and the fresh air module further includes an air guide, disposed on the insulation component and located within the air duct, the air guide guiding the air in the air duct to the first air vent for air outlet.

[0011] In some embodiments, the air guide has an inclined air guide surface that is arc-shaped to further facilitate airflow.

[0012] In some implementations, the height of the air guide surface gradually increases to further facilitate airflow.

[0013] In some implementations, the air guide and the insulation are integrally formed to ensure the stability of the connection between the air guide and the insulation.

[0014] In some implementations, the fresh air module further includes a sealing element disposed on the end face of the volute facing the insulation element; wherein the insulation element has a sealing groove, and the sealing element is embedded in the sealing groove to prevent air leakage.

[0015] In some embodiments, the insulation component has a sealing groove, and the end of the volute is embedded in the sealing groove to prevent air leakage.

[0016] In some implementations, the air duct is provided with an exhaust port, and the fresh air module further includes: a first air valve, which is located at the exhaust port and can switch between a first position and a second position; wherein, when the first air valve is in the first position, the first air valve opens the exhaust port, and when the first air valve is in the second position, the first air valve closes the exhaust port.

[0017] In some embodiments, the insulation component has a bottom surface and a stepped surface above the bottom surface, wherein when the first air valve is in the second position, the side of the first air valve abuts against the stepped surface to prevent air leakage.

[0018] In some embodiments, the volute has an air inlet, an air outlet, and a second air outlet communicating with the room; an exhaust outlet is provided in the air duct; the fresh air module further includes a housing for accommodating the insulation component and the volute, the housing including the base plate, and the housing having a return air outlet opposite to the base plate; the fresh air module further includes: a first air valve located at the exhaust outlet and switchable between a first position and a second position; a second air valve located at the air outlet for controlling the opening and closing of the air outlet; a third air valve located in the housing for controlling the opening and closing of the return air outlet; and an air guide component located in the insulation component and within the air duct, the air guide component guiding the air in the air duct to the first air outlet; In the fresh air module, when it is in fresh air mode, the first air valve is in the second position, the first air valve closes the exhaust port and opens the second air port, the second air valve opens the through air port, and the third air valve closes the return air port. Fresh air enters the room sequentially through the first air port, the through air port, the air inlet and the second air port. When the fresh air module is in waste air mode, the first air valve is in the first position, the first air valve opens the exhaust port and closes the second air port, the second air valve closes the through air port, and the third air valve opens the return air port. Waste air is discharged sequentially through the return air port, the air inlet and the exhaust port, the air guide and the first air port.

[0019] In some embodiments, the edge of the volute has a flange that abuts against the insulation element to ensure sealing performance.

[0020] In some implementations, the insulation component is provided with a wiring channel to facilitate wiring.

[0021] Based on the same inventive concept, this utility model also provides an air conditioner, including the aforementioned fresh air module. Attached Figure Description

[0043] It should be noted that all directional indications in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a specific posture. If the specific posture changes, the directional indications will also change accordingly.

[0044] In this utility model, unless otherwise explicitly specified and limited, the terms "connection," "fixing," etc., should be interpreted broadly.

[0045] Furthermore, in this utility model, descriptions involving "first," "second," etc., are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. Additionally, the technical solutions of the various embodiments can be combined with each other, but only on the basis of being achievable by those skilled in the art. When the combination of technical solutions is contradictory or impossible to implement, such a combination of technical solutions should be considered non-existent and not within the scope of protection claimed by this utility model.

[0046] This application is described below with reference to the accompanying drawings and specific embodiments:

[0047] The fresh air module and air conditioner provided in this embodiment aim to solve, to at least some extent, the technical problems of cumbersome installation operation and low installation efficiency of fresh air module volutes.

[0048] Figure 1 These are schematic diagrams of the fresh air module in some embodiments; Figure 2 for Figure 1 Top view of the fresh air module; Figure 3 for Figure 2 A cross-sectional view of the fresh air module along line AA. Combined with... Figure 1 , Figure 2 and Figure 3 The fresh air module of this application embodiment includes: a base plate 10, an insulation component 20, and a volute 30. The insulation component 20 is disposed on the base plate 10. The volute 30 is in contact with the insulation component 20 to form an air duct 70.

[0049] The insulation component 20 can be made of insulation foam.

[0050] The volute 30 can be made of plastic.

[0051] Since the insulation component 20 is located on the base plate 10, it can be supported by the base plate 10. Because the volute 30 contacts the insulation component 20 to form an air duct 70, the insulation component 20 can be part of the air duct 70, forming it together with the volute 30. This allows air to flow smoothly through the air duct 70. In other words, the traditional lower volute structure is unnecessary, simplifying the product structure, reducing material usage and manufacturing costs. The volute 30 can be directly placed on the insulation component 20, forming the air duct 70 through contact. This makes the assembly process quick and efficient, reducing installation difficulty and steps, and improving production efficiency. Furthermore, since the insulation component 20 can be part of the air duct 70, the air entering the air duct 70 will not contact the base plate 10, effectively isolating the base plate 10 from the influence of low external temperatures, reducing condensation, achieving insulation of the base plate 10, and improving the user experience.

[0052] In some embodiments, the insulation component 20 can not only serve as part of the air duct 70, but also provide insulation for the base plate 10, thus achieving dual functionality of the insulation component 20, reducing costs, simplifying installation, minimizing installation steps, and improving installation efficiency.

[0053] In some embodiments, in order to form an air duct 70, the volute 30 has an air inlet 301 and an opening 302 opposite to the air inlet 301. The insulation member 20 closes the opening 302 to form the air duct 70.

[0054] In some embodiments, the insulation component 20 closes the opening 302, so that the insulation component 20 and the volute 30 together form an air duct 70, allowing air to flow smoothly through the air duct 70. In other words, the lower volute of the traditional volute structure is not required, simplifying the product structure, reducing material usage and manufacturing costs. The volute 30 can be directly placed on the insulation component 20 to form the air duct 70, making the assembly process quick and efficient, reducing installation difficulty, reducing installation steps, and improving production efficiency. Moreover, the insulation component 20 can be part of the air duct 70, so that the air in the air duct 70 will not come into contact with the base plate 10, effectively isolating the base plate 10 from the influence of the external low temperature, reducing the occurrence of condensation, achieving insulation of the base plate 10, and improving the user experience.

[0055] Figure 5 for Figure 1 A schematic diagram showing the connection between the insulation components and the base plate of the fresh air module. (Combined with...) Figure 2 and Figure 5In some embodiments, to facilitate airflow, the volute 30 has a first air vent 303, and the fresh air module also includes an air guide 40. The air guide 40 is disposed on the insulation component 20 and located within the air duct 70. The air guide 40 can guide the air in the air duct 70 to the first air vent 303, allowing the air to be smoothly discharged through the first air vent 303, reducing wind resistance, improving airflow efficiency, ensuring stable airflow output, guaranteeing airflow volume, and improving the user experience.

[0056] In some embodiments, to further facilitate airflow, the air guide 40 has an inclined air guide surface 401. The air guide surface 401 is arc-shaped, which can guide the airflow to smoothly change direction, reducing the wind resistance caused by the sudden change in airflow direction. This allows the air to be smoothly discharged through the first air outlet 303, enabling the air to maintain a high speed when passing through the first air outlet 303, thus improving the airflow efficiency. At the same time, it reduces the obstruction encountered by the air when passing through the air guide surface, thereby reducing wind resistance, ensuring the airflow volume, and improving the user experience.

[0057] In some embodiments, to further facilitate airflow, the height of the air guide surface 401 gradually increases along the airflow direction. The air guide surface 401 can guide the airflow to turn smoothly, reducing the wind resistance caused by the abrupt change in airflow direction. This allows the air to be smoothly discharged through the first air outlet 303, enabling the air to maintain a high speed when passing through the first air outlet 303, thus improving the airflow efficiency. At the same time, it reduces the obstruction encountered by the air when passing through the air guide surface, thereby reducing wind resistance, ensuring the airflow volume, and improving the user experience.

[0058] In some embodiments, to ensure the stability of the connection between the air guide 40 and the insulation component 20, the air guide 40 and the insulation component 20 are integrally formed, so that there are no seams or connection points between the air guide 40 and the insulation component 20, thereby enhancing the structural strength, ensuring durability and reliability. Moreover, there is no need to install the air guide 40 and the insulation component 20 separately, thereby saving installation time and labor costs. At the same time, the position of the air guide 40 on the insulation component 20 can be determined, reducing assembly errors caused by the assembly of multiple parts and improving assembly accuracy.

[0059] Figure 4 for Figure 1 A schematic diagram of the volute structure of the fresh air module. (Combined with...) Figure 4 and Figure 5 In some embodiments, the volute 30 has a first air vent 303 and an air inlet 301. To prevent air leakage, the fresh air module further includes a sealing element 50. The sealing element 50 is disposed on the end face of the volute 30 facing the insulation element 20 and is located between the air inlet 301 and the first air vent 303. The insulation element 20 has a sealing groove 201, and the sealing element 50 is embedded in the sealing groove 201.

[0060] In some embodiments, the seal 50 is embedded in the sealing groove 201, so that the seal 50 is in contact with the inner wall of the sealing groove 201, and the tight fit between the seal 50 and the sealing groove 201 forms a continuous, seamless sealing interface, which can significantly reduce or eliminate the air leakage from the gap between the volute 30 and the insulation member 20, ensure the airflow efficiency within the air duct 70, ensure that the fresh air module can maintain good sealing performance during operation, ensure that the fresh air system can provide sufficient ventilation as required by the design, and improve the user experience.

[0061] In some embodiments, since the sealing element 50 is embedded in the sealing groove 201, the inner wall of the sealing groove 201 can clamp the sealing element 50, ensuring the connection stability between the volute 30 and the insulation element 20. Moreover, it realizes the limiting of the volute 30 on the insulation element 20, avoids the position of the volute 30 on the insulation element 20 from shifting, and ensures the stability of the volute 30 installed on the insulation element 20.

[0062] In some embodiments, the sealing groove 201 provides a clear installation position and guide for the sealing element 50, realizes the positioning of the volute 30 on the insulation element 20, ensures the accurate positioning of the volute 30 on the insulation element 20, saves installation time, and improves installation efficiency.

[0063] In some embodiments, in order to ensure the stability of the connection between the seal 50 and the volute 30, the seal 50 can be integrally formed with the volute 30, so that there are no seams or connection points between the air guide 40 and the insulation 20, thereby enhancing the structural strength, ensuring durability and reliability. Moreover, there is no need to install two separate air guides 40 and insulation 20, thereby saving installation time and labor costs. At the same time, the position of the air guide 40 on the insulation 20 can be determined, reducing assembly errors caused by the assembly of multiple parts and improving assembly accuracy.

[0064] In some embodiments, to prevent air leakage, a sealing groove 201 is provided on the insulation component 20, and the end of the volute 30 is embedded in the sealing groove 201 to form an embedded sealing structure. Compared with the traditional planar contact sealing method, the embedded sealing structure can provide a tighter fit, reduce the channels for air leakage, and make the sealing effect reliable. During long-term use, even if the end of the volute 30 experiences a certain degree of wear, it can still maintain good sealing performance due to the wrapping effect of the sealing groove 201, ensuring the sealing effect, reducing the number of equipment downtime maintenance due to sealing failure, and lowering maintenance costs.

[0065] Moreover, the presence of the sealing groove 201 constrains and positions the end of the volute 30, making the contact between the two more stable. Even if vibration occurs during equipment operation, a good sealing state can be maintained, thereby effectively avoiding energy loss due to air leakage and improving the working efficiency of the equipment.

[0066] Combination Figure 3 In some embodiments, the air duct 70 is provided with an exhaust port 701, and the fresh air module further includes a first air valve 60. The first air valve 60 is located at the exhaust port 701 and can switch between a first position and a second position. Specifically, when the first air valve 60 is in the first position, the first air valve 60 opens the exhaust port 701, and when the first air valve 60 is in the second position, the first air valve 60 closes the exhaust port 701.

[0067] In some embodiments, the first air valve 60 can switch between a first position and a second position to control the opening and closing of the exhaust vent 701, allowing users to adjust the intake of fresh air or exhaust of sewage according to actual needs, thus ensuring indoor air quality.

[0068] Combination Figure 3 and Figure 5 In some embodiments, to prevent air leakage, the insulation component 20 has a bottom surface 203 and a stepped surface 204 higher than the bottom surface 203. When the first air valve 60 is in the second position, the side of the first air valve 60 abuts against the stepped surface 204, ensuring a tight contact between the first air valve 60 and the insulation component 20, effectively preventing air leakage in the air duct 70 and enhancing the sealing performance. When the first air valve 60 is in the first position, the side of the first air valve 60 separates from the stepped surface 204 to open the exhaust port 701.

[0069] Figure 6 for Figure 1 A schematic diagram of the airflow path when the fresh air module is in fresh air mode; Figure 7 for Figure 1 A schematic diagram of the airflow path when the fresh air module is in the exhaust air mode; Figure 8 This is a schematic diagram of the structure of an air conditioner according to some embodiments. (Combined with...) Figure 1 , Figure 3 , Figure 6 , Figure 7 and Figure 8In some embodiments, to achieve the intake of fresh air and exhaust of sludge, the volute has an air inlet 301, an air outlet 304, a first air outlet 303 communicating with the outside and a second air outlet 305 communicating with the inside. An exhaust outlet 701 is provided within the air duct. The fresh air module includes a housing 80 for accommodating the insulation component and the volute. The housing 80 includes a base plate 10, and a return air outlet 801 is provided opposite to the base plate 10. The fresh air module also includes a guide element 40. The guide element 40 is disposed within the insulation component 20 and located within the air duct 70. The guide element 40 can guide the air within the air duct 70 to the first air outlet 303, allowing the air to be smoothly exhausted through the first air outlet 303. The fresh air module also includes a first air valve 60, a second air valve 90, a third air valve 100, and the guide element 40. The first air valve 60 is disposed at the exhaust outlet 701 and can be switched between a first position and a second position. The second air valve 90 is located at the air inlet 304 and is used to control the opening and closing of the air inlet 304. The third air valve 100 is located on the housing 80 and is used to control the opening and closing of the return air inlet 801. The air guide 40 is located on the insulation component 20 and inside the air duct 70. The air guide 40 can guide the air in the air duct 70 to the first air inlet 303. When the fresh air module is in the fresh air state, the first air valve 60 is in the second position, the first air valve 60 closes the exhaust air inlet 701 and opens the second air inlet 305, the second air valve 90 opens the air inlet 304, and the third air valve 100 closes the return air inlet 801. Fresh air enters the room sequentially through the first air inlet 303, the air inlet 304, the air inlet 301, and the second air inlet 305. When the fresh air module is in the exhaust air state, the first air valve 60 is in the first position, the first air valve 60 opens the exhaust port 701 and closes the second air port 305, the second air valve 90 closes the air inlet 304, and the third air valve 100 opens the return air port 801. The sewage air is discharged in sequence through the return air port 801, the air inlet 301, the exhaust port 701, the air guide 40 and the first air port 303.

[0070] In some embodiments, a fan is provided inside the volute 30, combined with Figure 6 When fresh air is needed, the fresh air module is put into fresh air mode, the fan is started, the first air valve 60 is in the second position, the first air valve 60 closes the exhaust port 701 and opens the second air port 305, the second air valve 90 opens the through air port 304, and the third air valve 100 closes the return air port 801. Outdoor fresh air enters the room sequentially through the first air port 303, through air port 304, air inlet 301, and second air port 305, thus achieving fresh air intake. At this time, the first air port 303 can serve as a fresh air inlet. Combined with... Figure 7When it is necessary to introduce or exhaust sewage air, the fresh air module is put into sewage exhaust mode, the fan is started, the first air valve 60 is in the first position, the first air valve 60 opens the exhaust port 701 and closes the second air port 305, the second air valve 90 closes the air inlet 304, and the third air valve 100 opens the return air port 801. The indoor sewage air is discharged in sequence through the return air port 801, the air inlet 301, the exhaust port 701, the air guide 40 and the first air port 303, thus realizing the sewage exhaust.

[0071] In some embodiments, only one air vent 304 and one air duct 70 are needed to deliver fresh outdoor air to the room and to expel stale indoor air in a timely manner. The structure is simple, which reduces costs and volume, reduces the space occupied by the fresh air module, and facilitates installation and layout.

[0072] In some embodiments, in order to ensure the structural strength of the volute 30, the edge of the volute 30 has a flange 306. The flange 306 can serve as a reinforcing structure for the edge of the volute 30, thereby increasing the rigidity and deformation resistance of the volute 30.

[0073] In some embodiments, in order to ensure sealing performance, the flange 306 abuts against the insulation component 20, increasing the contact area between the volute 30 and the insulation component 20. This allows for a tighter contact between the volute 30 and the insulation component 20, reducing gaps and air leakage points, improving the reliability of the seal, and effectively preventing air leakage in the air duct 70. The flange 306 can also improve the stability of the connection between the volute 30 and the insulation component 20.

[0074] Combination Figure 1 and Figure 5 In some embodiments, in order to supply air to the fresh air module, a driver is provided in the air duct 70. In order to control the driver, a cable is needed to electrically connect the driver and the controller of the fresh air module. In order to facilitate the wiring, the insulation component 20 is provided with a wiring trough 202. The cable can be run through the wiring trough 202. The wiring trough 202 provides a clear channel for the cable, enabling the installer to quickly and orderly arrange the cable, saving installation time and improving installation efficiency. Moreover, the wiring trough 202 can protect the cable from the direct impact of the outdoor environment, such as wear and corrosion. At the same time, it can also reduce the bending and twisting of the cable caused by random arrangement, thereby extending the service life of the cable.
