Description

Technical Field

[0001] This invention relates to the field of air conditioning technology, and more specifically, to a fresh air module and a fresh air air conditioner. Background Technology

[0002] Fresh air conditioners have a fresh air module that can introduce fresh outdoor air into the room, improving the freshness of the indoor environment.

[0003] In most fresh air modules, during the process of supplying fresh air into the room, the stale indoor air needs to be slowly squeezed out through door and window gaps under the pressure difference effect. The exhaust speed of the stale air is relatively low, resulting in a slow actual indoor air renewal speed. To solve this problem, a sludge removal function has been added to the fresh air module. This function uses a fan to draw the stale indoor air to the outside through the sludge inlet on the air conditioner casing, thereby accelerating the indoor air renewal speed. However, the existing fresh air modules have low extraction efficiency and still cannot meet the requirements of some users for indoor air freshness.

[0004] In summary, overcoming the aforementioned shortcomings of existing fresh air modules in fresh air conditioning systems is a technical problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0005] The purpose of this invention is to provide a fresh air module and a fresh air air conditioner to alleviate the technical problem of low exhaust efficiency in the fresh air modules of existing fresh air air conditioners.

[0006] The fresh air module provided by the present invention includes a fan, a first chamber and a second chamber, wherein the first chamber is connected to the air inlet of the fan and the second chamber is connected to the air outlet of the fan.

[0007] The first chamber is provided with a fresh air inlet and a first stale air inlet, and the second chamber is provided with a fresh air outlet and a stale air outlet. The fresh air outlet and the first stale air inlet are both connected to the interior, and the fresh air inlet and the stale air outlet are both connected to the exterior. The side wall at the fresh air outlet has a second stale air inlet, which is connected to the first chamber.

[0008] Valves are provided at the inner end of the fresh air outlet, the fresh air inlet, the first waste air inlet, the waste air outlet, and the second waste air inlet.

[0009] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0010] The fresh air module provided by this invention can achieve both fresh air and sewage discharge functions using the same fan. The opening and closing of valves can control the flow of corresponding channels, adapting to both functions. Furthermore, the fresh air inlet and the sewage inlet (including a first sewage inlet and a second sewage inlet) can share a first chamber, and the fresh air outlet and the sewage outlet can share a second chamber, simplifying the structure and saving space and cost. When the fresh air module is activated, the valves at the inner end of the fresh air outlet and at the fresh air inlet can be opened, while the valves at the first sewage inlet, the second sewage inlet, and the sewage outlet can be closed. This connects the first chamber to the fresh air inlet and the second chamber to the fresh air outlet. Outdoor fresh air is drawn into the first chamber through the fresh air inlet under the power of the fan; the fresh air entering the first chamber is drawn into the fan and discharged to the second chamber through the fan's outlet; subsequently, the fresh air in the second chamber is delivered indoors through the fresh air outlet. When the fresh air module activates the stale air function, the valves at the first stale air inlet, the second stale air inlet, and the stale air outlet can be opened, while the valves at the inner end of the fresh air outlet and the fresh air inlet are closed. This connects the first chamber with the first and second stale air inlets and the second chamber with the stale air outlet, allowing indoor stale air to enter the first chamber through the first and second stale air inlets. The stale air entering the first chamber is drawn into the fan and discharged to the second chamber through the fan's outlet. Subsequently, the stale air in the second chamber is discharged to the outside through the stale air outlet.

[0011] It should be noted that the fresh air module provided by this invention achieves two waste air inlets simply by setting a second waste air inlet on the side wall at the fresh air outlet, connecting the fresh air outlet to the first chamber. This eliminates the need for a separate waste air inlet channel, resulting in a larger total waste air inlet area and thus a larger waste air intake volume. This leads to higher efficiency in extracting indoor waste air, simplifying the structure and improving the indoor air renewal speed, which is beneficial for meeting the high requirements of some users for indoor air freshness. Furthermore, by adding a waste air inlet, the air intake area is increased. Compared to directly enlarging the waste air inlet, this method increases the air intake area without causing airflow dispersion in the first chamber due to an excessively large single air inlet, which is conducive to exhaust. Moreover, adding the first waste air inlet to the side wall of the original fresh air outlet of the fresh air module makes reasonable use of the limited structural space and protects the appearance of the air conditioner.

[0012] Preferably, as one possible implementation, a channel pipe is connected between the first chamber and the second chamber, one end of the channel pipe is connected to the first sewage inlet, and the other end of the channel pipe is connected to the first chamber.

[0013] The beneficial effects are that it makes reasonable use of the empty space between the channel pipe and the fresh air supply pipe, is less likely to interfere with other structures, and is easy to connect; in addition, it can improve the overall structure and stability.

[0014] Preferably, as one possible implementation, the channel tube is integrally formed with the first chamber.

[0015] The beneficial effect is that it helps reduce the number of parts and improves assembly efficiency.

[0016] Preferably, as one possible implementation, the outward orientation of the fresh air outlet is opposite to the outward orientation of the first waste air inlet.

[0017] The beneficial effect is that it helps improve the efficiency of wastewater suction and discharge, and increases the speed of air renewal.

[0018] Preferably, as one possible implementation, the fresh air outlet and the first waste air inlet face outward toward the left and right sides of the air conditioner, respectively.

[0019] The beneficial effects are that it improves the efficiency of waste gas extraction and has a better aesthetic appearance.

[0020] Preferably, as one possible implementation, the fresh air module further includes a sewage pipe, the inlet of which is connected to the sewage outlet, and the outlet of which is connected to the outside.

[0021] The beneficial effect is that the polluted air can be discharged smoothly.

[0022] Preferably, as one possible implementation, the fresh air module further includes a ventilation duct that leads to the outside and can introduce fresh outdoor air; the ventilation duct is provided with a drain outlet that is connected to the outlet of the drain pipe.

[0023] The benefits are that it not only saves on material costs, but also increases airflow while keeping the size of the holes in the wall the same.

[0024] Preferably, as one possible implementation, both the drain outlet and the drain pipe are located inside the air conditioner casing.

[0025] The benefits are twofold: firstly, it reduces the difficulty of storage and facilitates packing and transportation; secondly, it does not affect the appearance of the air conditioner, making the air conditioner more aesthetically pleasing after installation.

[0026] Preferably, as one possible implementation, the fresh air outlet is a tubular structure, and the second waste air inlet is opened on the pipe wall of the fresh air outlet.

[0027] The beneficial effect is that it helps to ensure the area of ​​the second sewage inlet.

[0028] The present invention also provides a fresh air air conditioner, which includes an air conditioner housing and the aforementioned fresh air module. The air conditioner housing has an air inlet, which is opposite to the first polluted air inlet.

[0029] The fresh air conditioner provided by this invention has all the advantages of the above-mentioned fresh air module, with high extraction efficiency, fast indoor air renewal speed, better exhaust effect, reasonable structural space utilization, and more aesthetically pleasing design.

[0038] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0039] The present invention will now be described in further detail with reference to specific embodiments and accompanying drawings.

[0040] See Figures 1-4 This embodiment provides a fresh air module 100, which not only has the function of supplying fresh air but also the function of exhausting stale air. It can use a fan to draw stale indoor air to the outside, resulting in a faster indoor air renewal speed. Based on this, the fresh air module 100 provided in this embodiment adds a stale air inlet (i.e., a second stale air inlet 133) on the side wall of the fresh air outlet 131. This not only increases the air intake volume and improves the efficiency of indoor stale air extraction, but also distributes the air intake area at the two stale air inlets, making it less likely that the air volume in the first chamber will be dispersed due to an excessively large single air inlet, which is beneficial for exhaust. In addition, the second stale air inlet 133 is added to the side wall of the original fresh air outlet 131 of the fresh air module 100, which can make reasonable use of the limited structural space and protect the appearance of the air conditioner.

[0041] The fresh air module 100 provided in this embodiment includes a fan 110, a first chamber 120, and a second chamber 130. The first chamber 120 is connected to the air inlet of the fan 110, and the second chamber 130 is connected to the air outlet of the fan 110. The first chamber 120 is provided with a fresh air inlet and a first stale air inlet 121, and the second chamber 130 is provided with a fresh air outlet 131 and a stale air outlet 132. The fresh air outlet 131 and the first stale air inlet 121 are both connected to the indoor environment, and the fresh air inlet and the stale air outlet 132 are both connected to the outdoor environment. The side wall of the fresh air outlet 131 has a second stale air inlet 133, which is connected to the first chamber 120. Valves are provided at the inner end of the fresh air outlet 131, the fresh air inlet, the first stale air inlet 121, the stale air outlet 132, and the second stale air inlet 133.

[0042] The fresh air module 100 provided in this embodiment can realize the fresh air function and the sewage discharge function with the same fan 110. The opening and closing of the valve can realize the opening and closing of the corresponding channels, respectively adapting to the fresh air function and sewage discharge function of the fresh air module 100. At the same time, the fresh air inlet and the sewage inlet (including the first sewage inlet 121 and the second sewage inlet 133) can share the first chamber 130, and the fresh air outlet 131 and the sewage outlet can share the second chamber 130, which helps to simplify the structure and save space and cost. When the fresh air module 100 activates the fresh air function, the valves at the inner end of the fresh air outlet 131 and the fresh air inlet can be opened, while the valves at the first stale air inlet 121, the second stale air inlet 133, and the stale air outlet 132 are closed, so that the first chamber 120 is connected to the fresh air inlet and the second chamber 130 is connected to the fresh air outlet 131. Outdoor fresh air can be drawn into the first chamber 120 through the fresh air inlet under the power of the fan 110. The fresh air entering the first chamber 120 can be drawn into the fan 110 and discharged into the second chamber 130 through the air outlet of the fan 110. Then, the fresh air in the second chamber 130 can be sent to the room through the fresh air outlet 131. When the fresh air module 100 activates the stale air function, the valves at the first stale air inlet 121, the second stale air inlet 133, and the stale air outlet 132 can be opened, while the valves at the inner end of the fresh air outlet 131 and the fresh air inlet are closed. This connects the first chamber 120 with the first stale air inlet 121 and the second stale air inlet 133, and connects the second chamber 130 with the stale air outlet 132. Indoor stale air can enter the first chamber 120 through the first stale air inlet 121 and the second stale air inlet 133. The stale air entering the first chamber 120 can be drawn into the fan 110 and discharged into the second chamber 130 through the fan 110's outlet. Subsequently, the stale air in the second chamber 130 can be discharged to the outside through the stale air outlet 132.

[0043] It should be noted that the fresh air module 100 provided in this embodiment only needs to be provided on the side wall at the fresh air outlet 131 to connect the fresh air outlet 131 to the second polluted air inlet 133 of the first chamber 120. There is no need to set up a separate polluted air inlet channel. It can achieve two polluted air inlets, and the total area of ​​polluted air entering is large. As a result, the polluted air intake volume is large, and the indoor polluted air extraction efficiency is high. In this way, not only is the structure simplified, but the indoor air renewal speed can also be improved, which can meet the high requirements of some users for indoor air freshness. In addition, by adding polluted air inlets, the air intake area is increased. Compared with directly enlarging the polluted air inlet, the air intake area is increased, and the air volume in the first chamber 120 will not be dispersed due to the single air inlet being too large, which is conducive to exhaust. Moreover, the second polluted air inlet 133 is added to the side wall of the original fresh air outlet 131 of the fresh air module 100, which can make reasonable use of the limited structural space and protect the appearance of the air conditioner.

[0044] Specifically, a channel pipe 140 can be connected between the first chamber 120 and the second chamber 130. One end of the channel pipe 140 is connected to the first waste air inlet 121, and the other end of the channel pipe 140 is connected to the first chamber 130. In this way, the channel pipe 140 can be used to achieve mutual communication between the first waste air inlet 121 on the fresh air outlet 131 and the first chamber 120, making reasonable use of the empty space between the first chamber 120 and the second chamber 130, avoiding interference with other structures, and facilitating connection. In addition, the channel pipe 140 can also be used to connect and fix the first chamber 120 and the second chamber 130, which can improve the overall structure and enhance structural stability.

[0045] In particular, the channel tube 140 and the first chamber 120 can be made into an integral structure, which helps to reduce the number of parts and improve assembly efficiency; of course, the channel tube 140 can also be made into a separate part and fixedly connected to the first chamber 120.

[0046] Preferably, the outward orientation of the fresh air outlet 131 is set to be opposite to the outward orientation of the first stale air inlet 121. In this way, stale air can be drawn in from two opposite directions of the air conditioner, which can reduce the mutual influence between the first stale air inlet 121 and the fresh air outlet 131 when stale air is discharged, which is conducive to improving the efficiency of stale air intake and exhaust and increasing the air renewal speed.

[0047] Furthermore, the fresh air outlet 131 and the first waste air inlet 121 can be set to face outwards to the left and right sides of the air conditioner, respectively. On the one hand, this can maximize the distance between the fresh air outlet 131 and the first waste air inlet 121, further reducing the mutual influence between the first waste air inlet 121 and the fresh air outlet 131 and improving the efficiency of waste air intake and exhaust. On the other hand, air conditioners are generally placed in the corner of the room, with the front facing the user's activity area. Therefore, users in front of the air conditioner are unlikely to see the fresh air outlet 131 and the first waste air inlet 121 located on the left and right sides of the air conditioner, resulting in better aesthetics.

[0048] In the specific structure of the fresh air module 100 provided in this embodiment, a drain pipe 150 can also be provided, with the inlet of the drain pipe 150 connected to the sewage outlet 132 and the outlet of the drain pipe 150 connected to the outside. In this way, after the indoor sewage air is sent into the second chamber 130 by the fan 110, it can enter the drain pipe 150 through the sewage outlet 132 and be discharged to the outside along the drain pipe 150, so that the sewage air can be discharged smoothly.

[0049] The fresh air module 100 provided in this embodiment also includes a ventilation duct 160, which is connected to the outside. When the fresh air module 100 activates the fresh air function, outdoor fresh air can be introduced by the ventilation duct 160 and sent to the room through the fresh air outlet 131. On this basis, a drain outlet can be opened on the ventilation duct 160 and connected to the outlet of the drain pipe 150. In this way, when the fresh air module 100 activates the drain function, the stale air in the drain pipe 150 can be discharged to the outside through the ventilation duct 160. That is to say, outdoor fresh air and indoor stale air can share a ventilation duct 160 connected to the outside, which can reduce the number of air conditioning pipes extending to the outside. This not only saves material costs, but also increases the air volume while keeping the hole size on the wall the same, so as to ensure the speed of indoor air renewal.

[0050] Specifically, the drain outlet and drain pipe 150 on the ventilation duct 160 are both located inside the air conditioner casing 200. The drain pipe 150 and the joint between the drain outlet and the drain pipe 150 are not exposed on the outside of the air conditioner. On the one hand, this reduces the difficulty of storage and makes it easier to pack and transport; on the other hand, it does not affect the appearance of the air conditioner, making the air conditioner more aesthetically pleasing after installation.

[0051] Specifically, the fresh air outlet 131 can be configured as a tubular structure, and the second waste air inlet 133 can be opened on the pipe wall of the fresh air outlet 131, which helps to ensure the area of ​​the second waste air inlet 133.

[0052] join Figure 4 This embodiment also provides a fresh air conditioner, which includes an air conditioner housing 200 and the aforementioned fresh air module 100. The air conditioner housing 200 has an air inlet, which is opposite to the first polluted air inlet 121.

[0053] In summary, the embodiments of the present invention disclose a fresh air module and a fresh air air conditioner, which overcome many technical defects of traditional fresh air air conditioner fresh air modules. The fresh air module and fresh air air conditioner provided by the embodiments of the present invention have high extraction efficiency, fast indoor air renewal speed, better exhaust effect, reasonable structural space utilization, and are more aesthetically pleasing.
