[0026] To make the objectives, technical solutions, and advantages of the embodiments of this disclosure clearer, the embodiments of this disclosure will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are merely illustrative of the embodiments of this disclosure and are not intended to limit the embodiments of this disclosure.
[0027] like Figures 1 to 4As shown, one embodiment of this disclosure proposes a cabinet-type fresh air unit, which includes: a housing 100, the housing 100 having a first chamber 110, a second chamber 120, and a third chamber 130 inside, the first chamber 110 being connected to an air inlet 170, the second chamber 120 being connected to a return air inlet 140 and an exhaust air outlet 160; the third chamber 130 being connected to an air supply outlet 150; the air supply outlet 150 being connected to an air supply fan, and the exhaust air outlet 160 being connected to an exhaust fan; the third chamber 130 being selectively connected to one of the first chamber 110 and the second chamber 120; and a purification mechanism 400 being installed in the third chamber 130.
[0028] In this embodiment, when the first chamber 110, the second chamber 120, and the third chamber 130 are not connected, the three chambers are independent, sealed spaces. The return air vent and the supply air vent are connected to the interior through corresponding pipes, and the exhaust air vent and the inlet air vent are connected to the outside through corresponding pipes. When the inlet air vent 170 is connected to the first chamber 110, the third chamber 130, and the supply air vent 150 in sequence, a fresh air duct is formed, which is used to introduce outdoor air into the interior. When the return air vent 140 is connected to the second chamber 120, the third chamber 130, and the supply air vent 150 in sequence, a return air duct is formed, which is used for indoor air circulation. When the return air vent 140 is connected to the exhaust air vent 160 through the second chamber 120, an exhaust air duct is formed, which is used to exhaust indoor air to the outside. The third chamber can be connected to the first and second chambers simultaneously, and the fresh air duct and return air duct are formed at the same time. When the air supply fan is started, outdoor air and indoor air enter the third chamber at the same time, mix, and then enter the room through the air supply outlet 150.
[0029] In this embodiment of the cabinet air conditioner, the exhaust duct and the fresh air duct can be formed independently and simultaneously, and the fresh air duct and the return air duct can be selectively connected. Generally, the exhaust duct and the return air duct are not used simultaneously, and only one of them is connected. Combined with the operation of the corresponding fan, indoor air circulation can be achieved, outdoor fresh air can be introduced into the room, indoor air can be exhausted to the outside, and fresh air circulation can be achieved simultaneously, with indoor air exhaust to the outside and outdoor fresh air introduced into the room.
[0030] When the exhaust duct and the fresh air duct are used simultaneously, indoor air is exhausted to the outside and outdoor fresh air is introduced into the room at the same time. The exhaust duct and the fresh air duct are independent of each other in the cabinet unit. Indoor air is exhausted to the outside and outdoor fresh air is introduced into the room at the same time without affecting each other, resulting in a significant ventilation effect.
[0031] The third chamber is used to install a purification mechanism. Air flowing through the fresh air duct and the return air duct will pass through the purification mechanism in the third chamber to achieve air purification.
[0032] In this embodiment of the cabinet unit, a mounting portion 190 is provided on the side wall with a larger area of the outer casing 100, such as... Figure 2 As shown, the mounting portion may include lugs disposed at the four corners of the corresponding sidewalls. The mounting portion may also be disposed on two opposite sidewalls along the length of the housing, with the lug holes facing the same side. A control unit 700 may also be disposed on the outside of one sidewall of the housing 100 for electrical connection with the supply fan and exhaust fan to control their operation.
[0033] like Figures 2 to 4 As shown, the cabinet unit also includes: a first partition 200 and a second partition 300 disposed within the outer casing 100. The first partition 200 divides the interior of the outer casing 100 into two chambers, and the chamber facing away from the four air vents is a third chamber 130, one of which is the third chamber 130. The second partition 300 is disposed in the other chamber, dividing the other chamber into the first chamber 110 and the second chamber 120.
[0034] That is, the air inlet is located on the side wall of the first chamber, and the air outlet and the return air outlet are respectively located on the side wall of the second chamber. The air supply outlet can be located on the side wall of the third chamber. In this embodiment, the position of the air supply outlet has been further improved by placing it on the side wall of the first chamber.
[0035] like Figure 2 and Figure 3 As shown, the first chamber 110 is provided with an air supply pipe 111 near the side wall of the outer shell 100 away from the second partition 300. The air supply pipe 111 is connected to the air outlet 150 and the third chamber 130 respectively. The air outlet 150, the air inlet 170, the air outlet 160 and the air return outlet 140 are provided on the side of the outer shell 100 away from the second partition 300 and are arranged sequentially along the length of the side of the outer shell 100.
[0036] The air supply pipe is located in the first chamber, connecting the air outlet located on the side wall of the first chamber to the third chamber. Because the air supply pipe is located in the first chamber, and the air outlet is connected to the third chamber via the air supply pipe, and the air inlet is connected to the third chamber via the first chamber, two airflows are generated within the first chamber, fully utilizing the cabinet structure, saving internal cabinet space, and reducing the overall size of the unit. Figure 1 As shown, the four air vents are located on the same side of the casing. This serves two purposes: firstly, it facilitates connection with the corresponding chambers to form corresponding channels; secondly, it makes the overall structure of the cabinet more compact and maximizes space utilization, achieving ventilation and air exchange of indoor air through flexible and varied channels.
[0037] like Figure 2 and Figure 3 As shown, the blower 500 is located in the third chamber 130 and is connected to the air supply pipe 111; the exhaust fan 600 is located in the second chamber 120 and is connected to the exhaust port 160.
[0038] The cabinet unit in this embodiment can achieve ventilation and air exchange of indoor air by starting the supply fan and exhaust fan.
[0039] Preferably, the second partition is disposed on the first partition and each side wall of the outer casing, dividing another chamber opposite the third chamber into a first chamber and a second chamber. The air supply outlet and air inlet are respectively disposed on both sides of the second partition.
[0040] The return air vent and the supply air vent are respectively located on the two sides of one side of the outer casing along its length. The air inlet and the exhaust air vent are located in the central area of one side of the outer casing along its length. The air inlet and the supply air vent are adjacent to each other, and the exhaust air vent and the return air vent are adjacent to each other. The supply air vent and the air inlet can be staggered, and the exhaust air vent and the return air vent can be staggered to save space and reduce the size of the cabinet. The first partition can be a flat structure, parallel to the side of the outer casing with four air vents, or it can be a stepped structure that is bent sequentially along the length of the cabinet, such as... Figure 3 As shown.
[0041] like Figure 3 As shown, the first partition 200 is provided with a first opening 210 and a second opening 220. The first opening 210 and the second opening 220 are adjacent to each other on both sides of the second partition 300. The first partition 200 includes a baffle 230, which can selectively open one of the first opening 210 and the second opening 220.
[0042] The first partition is also equipped with a driving mechanism (not shown in the figure). The baffle is rotatably disposed between the first opening and the second opening. Specifically, the baffle is positioned on the first partition away from the second partition. The baffle can be pivotally connected to the first partition via a rotating shaft. The driving mechanism is connected to the baffle, and the driving component can drive the baffle to rotate, selectively opening one of the first opening and the second opening. The driving component can be electrically connected to the control unit, which controls its operation to drive the baffle to rotate, opening one of the fresh air return channel and the return air channel while closing the other, or opening both the first opening and the second opening.
[0043] When the baffle opens the first opening and closes the second opening, the first chamber connects to the third chamber, forming a fresh air duct in conjunction with the air inlet and outlet. When the baffle opens the second opening and closes the first opening, the second chamber connects to the third chamber, forming a return air duct in conjunction with the return air inlet and outlet. When both the first and second openings are opened simultaneously, the fresh air duct and the return air duct are formed simultaneously.
[0044] like Figure 2 As shown, the first partition 200 is provided with a first opening 210 and a second opening 220. The first opening 210 is located in the first chamber 110 near the second partition 300, and the second opening 220 is located in the second chamber 120 near the side wall of the outer shell 100 away from the second partition 300.
[0045] This disclosure provides another way to separate the first opening and the second opening, and those skilled in the art can adjust the positions of the first opening and the second opening according to the actual situation.
[0046] like Figure 2 or Figure 3 As shown, the purification mechanism 400 is disposed on the side wall of the third chamber 130 away from the first chamber 110 and the second chamber 120. There is a reserved space 410 between the purification mechanism 400 and the first partition 200. The reserved space 410 is provided with a partition plate 411. The partition plate 411 is located on the side of the first opening 210 away from the second partition 300.
[0047] like Figure 3 As shown, when the first opening 210 and the second opening 220 are set separately, the reserved space 410 is also provided with a partition frame 412. The partition frame 412 is located on the side wall of the second opening 220 away from the outer shell 100, and the partition frame 412 forms a third opening 413. The first partition 200 includes a baffle 230, which can selectively open one of the second opening 220 and the third opening 413.
[0048] The purification mechanism has ventilation openings on both sides along its length, and there is space for air flow between the ventilation openings and the side wall of the outer shell. The partition plate divides the reserved space above the purification mechanism, so that the air entering from the first chamber and the second chamber passes through the third chamber according to a preset path. In other words, the air entering from the first opening or the second opening enters through the ventilation opening of the purification mechanism and flows out through the air outlet.
[0049] When the first opening and the second opening are separate, the first partition can be stepped with three steps. The second opening is located on the surface of the first step near the edge of the first partition, the first opening is located on the surface of the second step, and an air supply pipe is located on the surface of the third step. The baffle is pivotally mounted at the connection between the first and second steps, facilitating the selective opening of the second and third openings. The first partition is also equipped with a drive mechanism. The baffle can be connected to the first partition via a pivot shaft, and the drive mechanism is connected to the baffle. The drive mechanism can drive the baffle to rotate, selectively opening one of the first and second openings, or both. The drive mechanism can be electrically connected to the control unit, which controls its operation to drive the baffle to rotate, opening one of the fresh air return channel and the return air return channel while closing the other, or simultaneously opening the fresh air return channel and the return air return channel.
[0050] When the third opening is opened and the second opening is closed, the first and third openings connect, creating a fresh air duct between the first and third chambers. When the second opening is opened and the third opening is closed, the second and third chambers connect, creating a return air duct. When the third and second openings are opened simultaneously, the fresh air duct and the return air duct are formed simultaneously.
[0051] like Figure 2 and Figure 3 As shown, the outer casing 100 also has a fourth chamber 180, which is located on the side of the third chamber opposite to the first and second chambers, as shown. Figure 5 As shown, the fourth chamber 180 is provided with a drain assembly 181 for connection with the purification mechanism, and the side wall of the fourth chamber 180 is provided with a drain port 182.
[0052] The drainage assembly is connected to the drainage port through a corresponding pipe, which can discharge the liquid generated by the purification mechanism.
[0053] like Figure 6 As shown, as an example of a purification mechanism, the purification mechanism includes an electric field structure 800, which includes a plurality of spaced liquid film plates 810 and electrode plates 820, the liquid film plates being parallel to the electrode plates, at least one side of the liquid film plates being able to form a liquid film when fluid flows through it, and the electrode plates forming equally spaced air channels with adjacent liquid films.
[0054] A liquid inlet tank is provided at one end of the liquid film plate, and multiple outlets are evenly distributed in the inlet tank. Liquid flows through the outlets and forms a liquid film on the surface of the liquid film plate. Before the air flows through the electric field structure, the air particles are charged. When the charged dust and other impurities flow through the electric field structure, they move towards the liquid film plate and enter the liquid film under the action of the electric field force generated by the electrode plates. The fluid with impurities adsorbed by the electric field structure is discharged, thus purifying the air and cleaning the liquid film plate. The device for charging air particles can be set according to actual conditions and is not limited here. The charged properties of the air particles and the charged properties of the electrode plates can be set according to actual conditions. Other electric field structures can also be used to achieve the function of purifying air.
[0055] Turn on the air supply fan to connect the third chamber with the first chamber. Combine the air inlet and air outlet to activate the fresh air duct. Specifically, the second opening can be closed with a baffle, and the first or third opening can be opened. Outdoor air enters the first chamber through the air inlet, flows through the first opening, and enters the third chamber. If there is a third opening, the air enters the air inlet of the purification mechanism through the third opening, is purified by the purification mechanism, and is led out by the air supply fan to the air supply duct of the first chamber, flowing out of the air outlet, thus realizing the introduction of fresh air into the room.
[0056] Turn on the air supply fan to connect the third chamber with the second chamber. Combine the return air vent and the air supply vent to activate the return air duct. Specifically, you can use a baffle to open the second opening and close the first or third opening. Indoor air enters the second chamber through the return air vent, passes through the second opening, enters the third chamber, and passes through the air inlet of the purification mechanism. After being purified by the purification mechanism, the air is led out by the air supply fan to the air supply duct of the first chamber and flows out of the air supply vent, realizing the circulation of indoor air.
[0057] When the air supply fan is turned on, the third chamber is connected to the first and second chambers respectively, and the fresh air duct and return air duct are activated simultaneously to introduce fresh air into the room and circulate indoor air.
[0058] Turn on the exhaust fan to isolate and connect the second chamber with other chambers. Combine the return air vent and the exhaust vent to activate the exhaust duct. Specifically, a baffle can be used to close the second opening. Indoor air can be exhausted outdoors through the return air vent, the second chamber, and the exhaust vent.
[0059] The fresh air duct and exhaust duct can be used simultaneously without interference, allowing for both fresh air intake and indoor air exhaust. The specific operation of the fresh air duct, return air duct, and exhaust duct can be determined based on actual conditions.
[0060] Another aspect of this disclosure provides a fresh air system, including the cabinet unit described above.
[0061] The above description is only a preferred embodiment of the present disclosure. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present disclosure, and these improvements and modifications should also be considered within the protection scope of the present disclosure.
