[0047] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0048] Please also read Figures 1 to 4 , the ventilation and dehumidification device provided by the utility model is now described. The ventilation and dehumidification device includes an outer cover 1, a first air intake component 2, a second air intake component 3 and a condensing module 4. The first air intake component 2 is arranged inside the outer cover 1; the first air intake component 2 is connected to a first air outlet pipeline 23, and the first air outlet pipeline 23 is used to exhaust air to the outside; the second air intake component 3 is arranged inside the outer cover 1; the second air intake component 3 and the first air intake component 2 are independent of each other; the condensing module 4 is arranged inside the outer cover 1, and is located at the air outlet end of the second air intake component 3.

[0049] The ventilation and dehumidification device is generally installed indoors, and the outlet end of the first air outlet pipe 23 extends out of the room. The first air intake assembly 2 and the second air intake assembly 3 can absorb indoor air respectively. The air absorbed by the first air intake assembly 2 is discharged outdoors from the first air outlet pipe 23, and the first air intake assembly 2 plays the role of exhausting air; the air absorbed by the second air intake assembly 3 passes through the condensing module 4.

[0050] It should be noted that the first air intake assembly 2 and the second air intake assembly 3 are independent of each other, which means that they operate independently, opening and closing do not affect each other, and the air flow paths of the two are not connected. The first air intake assembly 2 and the second air intake assembly 3 are electrically controlled to open and close through the driving module 5.

[0051] When it is necessary to replace the indoor air, the first air suction component 2 can be turned on separately, and the first air suction component 2 draws the turbid air indoors to the outdoors to achieve the function of exhausting air; when it is necessary to dehumidify the indoor air, the second air suction component 3 can be turned on separately, and the second air suction component 3 sends the humid air to the condensing module 4, and the condensing module 4 condenses the moisture in the air and converts it into liquid water to reduce the humidity. Of course, the first air suction component 2 and the second air suction component 3 can also be turned on at the same time, so that the ventilation and dehumidification device can play the role of exhausting air and dehumidifying at the same time.

[0052] The ventilation and dehumidification device provided by the utility model has a first air intake component 2 and a second air intake component 3 arranged in an outer cover body 1, and the first air intake component 2 plays a role of exhausting air; the second air intake component 3 and the condensing module 4 play a role of dehumidification; and the first air intake component 2 and the second air intake component 3 are independent of each other and do not interfere with each other, so that the dehumidification and exhaust actions can operate independently or work together, and the user can adjust according to the installation site environment, thereby improving convenience; compared with the prior art, the ventilation and dehumidification device provided by the utility model is suitable for application in high temperature and humid areas.

[0053] In some embodiments, the condensing module 4 may be configured as follows: Figure 5 The structure shown, see Figure 5 The condensing module 4 includes a cooling fin 41, a condenser 42 and a radiator 43. The cooling fin 41 has a condensing surface and a heating surface; the condenser 42 is arranged in contact with the condensing surface; and the radiator 43 is arranged in contact with the heating surface.

[0054] Preferably, the cooling plate 41 is a PTC cooling plate 41. When the PTC cooling plate 41 is energized, a thermoelectric effect is formed, so that one side surface becomes a condensation surface and the other side surface becomes a heating surface. The condensation surface and the heating surface are arranged opposite to each other.

[0055] The condenser 42 and the radiator 43 can be fixed inside the outer housing 1 respectively, and the condenser 42 directly contacts the indoor air output by the second air intake assembly 3 without isolation. The condenser 42 condenses the moisture in the air and converts it into liquid water. The heat generated during the condensation process can be centrally recovered by the radiator 43.

[0056] The above-mentioned condensing module 4 does not have an air compressor, and the condenser 42 can be used to directly dehumidify the moisture, which greatly reduces the production cost and the subsequent use cost; and the condenser 42, the cooling plate 41 and the radiator 43 are arranged in sequence, occupying a small space, and the overall volume of the ventilation and dehumidification device can be optimized.

[0057] Preferably, see Figure 4On the basis of the above embodiment, the radiator 43 is located at the outlet end of the second air intake assembly 3; the condensing module 4 further includes a second air outlet pipeline 45. The air inlet of the second air outlet pipeline 45 is aligned with the radiator 43, and the air outlet leads to the room. The second air outlet pipeline 45 is used to exhaust air to the room.

[0058] The radiator 43 is arranged at the air outlet end of the second air intake component 3. The heat concentrated by the radiator 43 can be sent to the room through the second air outlet duct 45 under the drive of the airflow inside the second air intake component 3. In other words, the heat generated during the condensation process can be converted into hot air and passed into the room, providing dry air for the room and improving the indoor comfort.

[0059] A second air outlet duct 45 is added at the radiator 43. On the one hand, the recovered heat can be led to the room, forming an internal circulation dehumidification mode, making the room a dry and comfortable environment; on the other hand, the air circulates inside the room without the need to exhaust outside, reducing noise and making the room a quiet and comfortable environment.

[0060] In some embodiments, the condensing module 4 can also be used as follows Figure 5 The structure shown, see Figure 5 The condensing module 4 further includes a shell 44. The shell 44 is disposed inside the outer housing 1; wherein the radiator 43 is located inside the shell 44, and the air inlet of the second air outlet duct 45 is connected to the inner cavity of the shell 44. The shell 44 is used to encapsulate the radiator 43 and collect the heat recovered by the radiator 43 to prevent the heat from diffusing and volatilizing.

[0061] In addition, the shell 44 has a vent 443 connected to the air outlet end of the second air intake component 3; the vent 443 is used for air passing, and the air in the second air intake component 3 is blown toward the radiator 43 through the vent 443 to take away the heat of the radiator 43, forming hot air, and then passing into the room through the second air outlet duct 45.

[0062] Preferably, the housing 44 includes a first half shell 441 and a second half shell 442. Figure 5 As shown, the first half shell 441 is close to the cooling fin 41, and the second half shell 442 is close to the air outlet of the second air intake assembly 3. The first half shell 441 and the second half shell 442 are butt-jointed to form a housing 44. The vent 443 is provided on the second half shell 442.

[0063] It should be noted that the opening area of ​​the air outlet of the second air intake component 3 is larger than the occupied area of ​​the shell 44 . Therefore, part of the air output by the second air intake component 3 is blown toward the radiator 43 , and part of the air flows toward the condenser 42 .

[0064] Preferably, see Figure 5In order to ensure that the heating surface of the cooling fin 41 fits the radiator 43 without any obstacles, a limiting hole 444 is provided on the side wall of the housing 44, and the cooling fin 41 is embedded in the limiting hole 444. Specifically, the limiting hole 444 is provided on the first half housing 441, and the cooling fin 41 can be completely embedded and limited in the limiting hole 444.

[0065] The limiting holes 444 are arranged on the shell 44 , which can not only avoid interference caused by the shell 44 and ensure smooth fitting between the heating surface and the radiator 43 , but also enable the shell 44 to support and limit the cooling fins 41 , thereby improving the assembly stability of the condensing module 4 .

[0066] In some embodiments, the heat sink 43 may be configured as follows: Figure 5 The structure shown, see Figure 5 The radiator 43 includes a heat dissipation plate 431 and a plurality of heat dissipation fins 432. One side of the heat dissipation plate 431 is arranged in contact with the heating surface; the plurality of heat dissipation fins 432 are respectively connected to the other side of the heat dissipation plate 431; the plurality of heat dissipation fins 432 are parallel and spaced apart, and the spacing directions of the plurality of heat dissipation fins 432 are respectively perpendicular to the axial direction of the vent 443 and the axial direction of the air inlet of the second air outlet duct 45.

[0067] The heat sink 431 is used to fit the heating surface of the cooling fin 41 to increase the heat exchange area; in addition, the heat sink 431 also has the function of integrating a plurality of heat sink fins 432 .

[0068] The spacing directions of the plurality of heat dissipation fins 432 are respectively perpendicular to the axial direction of the vent 443 and the axial direction of the air inlet of the second air outlet duct 45. It can be understood that the spacing directions of the plurality of heat dissipation fins 432, the axial direction of the vent 443, and the axial direction of the air inlet of the second air outlet duct 45 are perpendicular to each other. The plurality of heat dissipation fins 432 are arranged at intervals in the above manner, which can ensure that the air transported by the second air intake assembly 3 passes smoothly through the spacing spaces of the plurality of heat dissipation fins 432, takes away the heat on the heat dissipation fins 432, and leads to the second air outlet duct 45.

[0069] See also Figure 1 , Figure 3 and Figure 4 In some embodiments, the condensing module 4 further includes a water tank 46 and a drain pipe 47. The water tank 46 is disposed inside the outer housing 1 and is disposed below the condenser 42. One end of the drain pipe 47 is connected to the water tank 46, and the other end extends out of the outer housing 1.

[0070] The water tank 46 is fixed and covered below the condenser 42, and the installation position of the water tank 46 is rationally planned, which saves space and facilitates the collection of condensed water.

[0071] In some embodiments, the first air intake component 2 and the second air intake component 3 may also be used as follows: Figures 1 to 4 The structure shown, see Figures 1 to 4 The first air suction component 2 includes a first annular air duct 21 and a first motor group 22: the air outlet end of the first annular air duct 21 is connected to the first air outlet pipeline 23; the first motor group 22 is arranged in the central ring hole of the first annular air duct 21, and is used to suck indoor air into the first annular air duct 21.

[0072] The second air suction assembly 3 includes a second annular air duct 31 and a second motor group 32. The air outlet end of the second annular air duct 31 is connected to the condensing module 4; the second motor group 32 is arranged in the central annular hole of the second annular air duct 31, and is used to suck the indoor air into the second annular air duct 31; wherein the first annular air duct 21 and the second annular air duct 31 are not connected to each other.

[0073] The central ring hole of the first annular air duct 21 is the air inlet of the first annular air duct 21, and the central ring hole of the second annular air duct 31 is the air inlet of the second annular air duct 31. After the first motor group 22 and the second motor group 32 are started, the indoor air is introduced into the first annular air duct 21 / the second annular air duct 31 through the central ring hole.

[0074] The first motor group 22 is arranged in the central ring hole of the first annular air duct 21, and the second motor group 32 is arranged in the central ring hole of the second annular air duct 31. On the premise of ensuring that the first annular air duct 21 / the second annular air duct 31 has sufficient air inlet space, the occupied space of the first motor group 22 / the second motor group 32 is reduced, so that the ventilation and dehumidification device has the characteristics of compact structure.

[0075] In some embodiments, the ventilation and dehumidification device further comprises a driving module 5. The driving module 5 is fixedly arranged in the inner cavity of the outer housing 1, and is electrically connected to the first air intake assembly 2, the second air intake assembly 3, and the condensing module 4 respectively; a humidity sensor 51 is arranged in the driving module 5.

[0076] The driving module 5 can control the start-up of the first air suction component 2, the second air suction component 3 and the condensing module 4. The first air suction component 2 can be turned on separately, and the second air suction component 3 and the condensing module 4 can also be turned on separately. In other words, the dehumidification and exhaust actions can be operated separately or in coordination.

[0077] The humidity sensor 51 is used to monitor the air humidity in the first annular air duct 21 and the second annular air duct 22. When the monitored humidity value received by the driving module 5 is lower than a predetermined value, the driving module 5 can control the second air intake component 3 and / or the condensing module 4 to shut down, and the condensing module 4 no longer implements the dehumidification function.

[0078] In addition, users can set the dehumidification level (i.e. set a preset value) and timing function to meet personal needs and save energy.

[0079] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
