Description

Air interchanger

Technical Field

The utility model relates to the technical field of household appliances, in particular to a ventilation device.

Background

The air interchanger for indoor air interchange includes a casing, an air inlet and an air outlet on the casing, an air interchanger unit for sending air from the air inlet to the air outlet, and a joint at the downstream of the air outlet and with at least one part projecting from the casing. When the air interchanger operates, under the action of the air interchanging unit, indoor air is blown out from the air inlet to the air outlet and then is blown out of the basket body through the joint. Therefore, the dirty air in the room can be discharged to the outside, and the ventilation in the room can be realized.

When the outdoor air temperature is low and the indoor air is in a high-temperature and high-humidity state, the high-temperature and high-humidity indoor air is blown to the joint by the ventilation unit. When the high-temperature and high-humidity indoor air contacts the joint portion protruding outside the housing and having a lower surface temperature, water drops are condensed on the inner surface of the joint. The water droplets may drain out of the room along the joint or pipe, causing water droplets. Even in winter, when outdoor air is very low, water droplets may freeze at the mouth of the duct, forming icicles.

First, the ventilation device of the present invention will be described with reference to the drawings.

According to the ventilation device of the present invention, the ventilation device is placed in a storage space that cannot be directly viewed by a user, such as above a ceiling, and is connected to a ventilation duct, thereby dehumidifying air or adjusting temperature of each space.

Fig. 1 is a schematic structural view illustrating a ventilation apparatus according to an embodiment of the present invention. Fig. 2 is a schematic structural view illustrating a ventilation unit according to an embodiment of the present invention.

Referring to fig. 1 to 2, the ventilation device 10 includes: the air conditioner includes a housing 100, an air outlet 102, a ventilation unit 200, an exhaust air passage 300, and a drainage structure 400.

The enclosure 100 has a hollow rectangular parallelepiped shape, and includes an upper surface 110 located above and forming the outer contour of the ventilation device 10, a lower surface 120 facing the upper surface 110, and a side surface 130 connecting the upper surface 110 and the lower surface 120. The housing 100 includes an air inlet 101.

The intake vent 101 is an opening provided in the lower surface 120 of the enclosure 100 for allowing air to enter the interior of the enclosure 100.

The outlet 102 is provided outside the enclosure 100, specifically, outside the side surface 130 of the enclosure 100, and blows air inside the enclosure 100 out of the enclosure 100.

The ventilation unit 200 is provided in the enclosure 100, and blows air that has entered the enclosure 100 from the air inlet 101 to the air outlet 102 through the ventilation unit air outlet 202. The ventilation unit 200 includes a ventilation unit inlet 201, a ventilation unit outlet 202, fan blades 210, a motor 220, and a snail shell 230.

The motor 220 drives the fan blades 210 to rotate, thereby generating an air flow to suck air into the ventilation unit 200.

The snail shell 230 accommodates the fan blade 210, and includes a first rolling plate having a ventilation unit air inlet 201 for air to enter an inner side of the snail shell 230, a second rolling plate 232 opposite to the first rolling plate, and a snail shell side wall 233 connecting the first rolling plate and the second rolling plate 232. The first rolling plate, the second rolling plate 232 and the snail shell side wall 233 enclose the ventilation unit air outlet 202 for blowing out air. In this embodiment, the snail shell 230 is disposed longitudinally with respect to the ground, i.e. the first rolling plate and the second rolling plate 232 are disposed longitudinally with respect to the ground. By longitudinally disposed, it is meant that the extension of the plane in which the first wrap and the second wrap 232 lie intersects the ground.

As shown in fig. 3, the snail shell 230 also includes a snail shell drain 240. The snail shell drain port 240 is provided at a position (lowest position) where the distance from the snail shell 230 to the ground is shortest (closest to the ground) in the installed state. The snail shell drain 240 communicates the interior of the snail shell 230 with the interior of the basket 100. In this embodiment, the snail shell drain 240 is located on the side wall 233 of the snail shell at the shortest distance from the ground.

The exhaust air duct 300 communicates between the ventilation unit outlet 202 and the outlet 102 to blow air from the ventilation unit outlet 202 to the outlet 102, that is, the air discharged from the ventilation unit outlet 202 is discharged to the outside space of the enclosure 100 through the exhaust air duct 300.

In this embodiment, the exhaust air path 300 may be provided as a joint for connecting the ventilation unit outlet 202 and the outlet 102. The inlet on the inner side of the joint is connected with the air outlet 202 of the ventilation unit, and the outlet on the outer side of the joint is the air outlet 102 and is communicated with the outdoor space outside the basket 100.

The ventilator 10 further includes a drain structure 400, and the drain structure 400 is provided on the discharge air path 300 located in the casing 100 and communicates the discharge air path 300 with the internal space of the casing 100. The drain structure 400 is provided at the lowest position of the lower exhaust air passage 300 closest to the ground in the mounted state, specifically, at a position where the inner wall of the exhaust air passage is closest to the ground.

Fig. 3 is a schematic structural view illustrating a drainage structure according to an embodiment of the present invention.

The drain structure 400 includes a first drain port 401, a first drain space 410, a second drain space 420, a second drain port 402, and a third drain port 403.

The first exhaust port 401 is provided in the exhaust air passage 300 and communicates with the exhaust air passage 300. In the present embodiment, when the discharge air duct 300 is provided as a joint, the first discharge port 401 is an opening provided in the joint and communicating the inside of the joint with the inside of the housing 100. The first exhaust port 401 is provided at the lowest position of the exhaust air passage 300.

The first drainage space 410 is provided below the exhaust air duct 300 and communicates with the first drainage port 401. The first drainage space 410 includes: a first drainage space side wall 411 and a first drainage space bottom wall 412. The first drain space sidewall 411 includes a first drain space inner sidewall 441 and a first drain space outer sidewall 442 formed to extend downward from the discharge wind part 300 at both sides of the first drain port 401. First drain space bottom wall 412 extends between first drain space outer side wall 442 and first drain space inner side wall 441. Thus, when the water vapor in the air flowing through the discharge air duct 300 forms dew condensation water upon cooling, the dew condensation water enters the first discharge space 410 formed by the first discharge space side wall 411 and the first discharge space bottom wall 412 from the first discharge port 401 and is discharged from the discharge air duct 300, and is prevented from freezing at the outlet port 102, which is the outer outlet of the discharge air duct 300. Specifically, the dew condensation water in the exhaust air duct 300 drops downward from the first exhaust port 401 into the first exhaust space 410, and then flows along the first exhaust space bottom wall 412.

Note that the first drain space inner side wall 441 and the first drain space outer side wall 442 of the present invention may be formed to extend downward from the inside and the outside of the first drain port 401, respectively. However, the present invention is not limited thereto, and the first and second drain space outer sidewalls 441 and 442 may be formed to extend downward from both left and right sides of the first drain port 401.

The second drain port 402 communicates with the first drain space 410 and is disposed offset from the first drain port 401. The misalignment of the second drain opening 402 and the first drain opening 401 indicates that the second drain opening 402 and the first drain opening 401 are not aligned with each other, preventing air from entering the first drain opening 401 into the first drain space 410 and then directly entering the second drain opening 402 to generate a whistle. The air blown out from the ventilating unit outlet 202 has a relatively high wind speed, and if the first drain port 401 is aligned with the second drain port 4402, the air passes through the second drain port 402 at a relatively high wind speed after passing through the first drain port 401 at a relatively high speed, so that a whistle sound is generated. However, since the first drain port 401 and the second drain port 402 are not aligned with each other, when air passes through the first drain port 401 at a high wind speed, the air first collides with the first drain port bottom wall 412, and the wind speed is reduced and then the air is blown toward the second drain port 402, thereby suppressing the generation of noise. Specifically, the first drain port 401 is adjacent to the first drain space outer side wall 442, and the second drain port 402 is adjacent to the first drain space inner side wall 441. In this embodiment, the first drain space bottom wall 412 may extend from the first drain space outer side wall 442 toward the first drain space inner side wall 441, but is spaced apart from the first drain space inner side wall 441, and the spaced-apart gap is formed as the second drain opening 402.

However, the present invention is not limited thereto, and the first drain port 401 may be adjacent to the first drain space inner sidewall 441, and the second drain port 402 may be adjacent to the first drain space outer sidewall 442 to be staggered from the first drain port 401. In this case, the first drain space bottom wall 412 may extend from the first drain space inner side wall 441 toward the first drain space outer side wall 442, but be spaced apart from the first drain space outer side wall 442. The spaced gap is formed as a second drain opening 402.

According to another embodiment, first drain space bottom wall 412 may extend between and be connected to both first drain space outer sidewall 442 and second drain space inner sidewall 441. In this case, the second drain port 402 may be formed in the first drain space bottom wall 412 so as to extend through the opening of the first drain space bottom wall 412.

The second drain space 420 is provided below the first drain space 410 and communicates with the second drain port 402. The dew-condensed water introduced into the first drainage space 410 may flow down into the second drainage space 420 through the second drainage port 402.

The second drainage space 420 includes second drainage space side walls 421 and a second drainage space bottom wall 422. In the present embodiment, the first drain space bottom wall 412 is spaced apart from the first drain space inner side wall 441 to form the second drain port 402, and in this case, the second drain space side wall 421 includes a second drain space inner side wall 461 formed extending downward from the lower end of the first drain space inner side wall 441 and a second drain space outer side wall 462 formed extending downward from the first drain space bottom wall 412. The second drain space bottom wall 422 is formed extending between the second drain space inner side wall 461 and the second drain space outer side wall 462. Thus, the dew water flowing along the first drain space bottom wall 412 in the first drain space 410 drops from the second drain port 402 into the second drain space 420. Specifically, the water drops onto the second drain space bottom wall 422 of the second drain space 420, and then flows along the second drain space bottom wall 422 until flowing out of the second drain space 420.

However, the present invention is not limited thereto, and when the first drain space bottom wall 412 is spaced apart from the first drain space outer sidewall 442 to form the second drain opening 402, the second drain space sidewall 421 includes a second drain space outer sidewall 462 formed to extend downward from the lower end of the first drain space outer sidewall 442 and a second drain space inner sidewall 461 formed to extend downward from the first drain space bottom wall 412.

According to another embodiment, when the first drain space bottom wall 412 is connected to both the first drain space outer side wall 442 and the first drain space inner side wall 441, the second drain space side wall 421 includes a second drain space outer side wall 462 and a second drain space inner side wall 461 formed to extend downward from the first drain space bottom wall 412 at both sides of the second drain opening 402.

The third drain port 403 communicates the second drain space 420 with the inside of the housing 100 and is offset from the second drain port 402. The misalignment of the second drain opening 402 and the third drain opening 403 means that the second drain opening 402 and the third drain opening 403 are not aligned with each other, and the air entering the second drain space 420 from the second drain opening 402 is prevented from directly entering the third drain opening 403 and causing noise. Specifically, the second drain opening 402 is adjacent to the second drain space inner side wall 461, and the third drain opening 403 is adjacent to the second drain space outer side wall 462.

That is, the first drain port 401 and the third drain port 403 are both disposed on the same side, i.e., on the side of the first drain space outer side wall 442, and the second drain port 402 is disposed on the opposite side of the first drain space inner side wall 441.

However, the present invention is not limited thereto, and when the first drain port 401 is provided at the side of the inner sidewall 441 of the first drain space, the second drain port 402 may be provided at the side of the outer sidewall 442 of the first drain space, and the third drain port 403 may be provided at the side of the inner sidewall 441 of the first drain space.

In this embodiment, the first drain port 401 is disposed near the first drain space outer sidewall 442, and the second drain port 402 is disposed near the first drain space inner sidewall 441, the second drain space bottom wall 422 may extend from the second drain space inner sidewall 461 toward the second drain space outer sidewall 462, but is spaced apart from the second drain space outer sidewall 462, and the spaced-apart gap is formed as the third drain port 403. However, the present invention is not limited thereto, and the first drain port 401 is provided on the side close to the first drain space inner side wall 441, and the second drain port 402 is provided on the side close to the first drain space outer side wall 442, and the second drain space bottom wall 422 may extend from the second drain space outer side wall 462 toward the first drain space inner side wall 461, but be spaced apart from the second drain space inner side wall 461, and the spaced-apart gap is formed as the third drain port 403.

According to another embodiment, the second drain space bottom wall 422 may extend between the second drain space inner side wall 461 and the second drain space outer side wall 462, and be connected to both the second drain space inner side wall 461 and the second drain space outer side wall 462. In this case, the third drain port 403 is an opening provided in the second drain space bottom wall 422, penetrating the second drain space bottom wall 422, and communicating the second drain space 420 with the space inside the housing 100.

The diameters of the first drain port 401, the second drain port 402, and the third drain port 403 are 5mm or more²To prevent water droplets from failing through the drain opening due to surface tension.

The following describes an embodiment of the ventilation device in this embodiment.

When the ventilation device 10 of the present embodiment is operated, the air in the enclosure 100 enters the snail shell 230 through the ventilation unit inlet 201, enters the exhaust air duct 300 through the ventilation unit outlet 202, and is blown out of the enclosure 100 through the outer outlet 302 of the exhaust air duct 300 by the ventilation unit 200.

When the indoor air is in a high temperature and high humidity state, such as a room in a bathroom or the like, and the outdoor air temperature is low, the high temperature and high humidity indoor air enters the enclosure 100 through the air inlet 101 of the enclosure 100, enters the ventilation unit 200, and is blown out of the enclosure 100. Since the outdoor air temperature is low, the surface temperature of the joint constituting the discharge air passage 300 is close to that of the outdoor air, and the surface temperature of the joint is low compared to the air in the casing 100.

When high-temperature and high-humidity air enters the exhaust air duct 300 and contacts a surface having a low joint temperature, dew condensation may occur. Water droplets formed by condensation will adhere to the joint surface.

Since the first drain port 401 is provided in the exhaust air passage 300, particularly, at the lowest position of the exhaust air passage 300, the water droplets attached to the joint surface are discharged out of the exhaust air passage 300 through the first drain port 401 by gravity.

Thereby, the water droplets are prevented from dropping from the outer outlet 302 of the exhaust air duct 300 along with the air blown out of the housing 100, and from freezing.

Since the first and second drainage spaces 410 and 420 are provided below the exhaust air path 300, when water drops are discharged from the first drainage port 401 by gravity into the exhaust air path 300, the water drops enter the first drainage space 410 and fall on the first drainage space bottom wall 412.

The second drain port 402 is provided in the first drain space bottom wall 412, and the second drain port 402 is provided on the opposite side of the first drain port 401. When more water droplets accumulate on the bottom wall 412 of the first drainage space until they accumulate at the second drainage outlet 402, the water droplets will drain out of the first drainage space 410 through the second drainage outlet 402 by gravity.

Since the second water discharge port 402 is provided on the opposite side of the first water discharge port 401, not directly below the first water discharge port 401, the air blown toward the outlet port 102 from the outlet air duct 300 can be prevented from passing through the first water discharge port 401 and the second water discharge port 402 and generating a whistle.

This can suppress the generation of noise while discharging water.

The first drain space side wall 411 is further provided with an inclined surface 450 inclined from the first drain space outer side wall 442 toward the first drain space inner side wall 441 and toward the first drain space bottom wall 412. When the water droplets are discharged from the first drain port 401 to the outside of the discharge air passage 300, the water droplets are discharged more quickly from the first drain space 410 by flowing along the inclined surface 450 to the side of the first drain space bottom wall 412 where the second drain port 402 is provided.

Since the ventilation device 10 is provided with the second drain space 420, and the third drain port 403 is provided on the second drain space 420 on the side close to the first drain port 401. When the water droplets are discharged out of the first drain space 410 through the second drain port 402 by gravity, the water droplets enter the second drain space 420 downward and are discharged into the housing 100 through the third drain port 403.

The first drain port 401 and the third drain port 403 are disposed on the same side, and the second drain port 402 is disposed on the opposite side, and a first drain space bottom wall 412 and a second drain space bottom wall 422 are disposed therebetween.

When air enters the first drainage space 410 through the first drainage port 401, the air is interfered by the first drainage space bottom wall 412 and the second drainage space bottom wall 422, so that the wind speed is reduced, drainage is performed, and the generation of noise is suppressed.

Further, since the outlet 102 is connected to the outdoor space with a low temperature, the temperature of the air in the exhaust air duct 300 is low when the ventilation device 10 is not in operation. When the ventilator 10 is operated, the high-temperature and high-humidity indoor air meets the low-temperature air in the exhaust air path 300 at the boundary between the ventilation unit outlet 202 and the exhaust air path 300. When the temperature difference is large, dew condensation may be formed at the boundary between the ventilation unit outlet 202 and the inner inlet of the exhaust air passage 300. At this time, water droplets may flow along the snail shell side wall 233 into the inside of the snail shell 230.

Because the lowest part of the snail shell 230 is provided with the snail shell drain 240, water drops entering the inner side of the snail shell 230 flow to the snail shell drain 240 under the action of gravity and then are discharged out of the snail shell 230 through the snail shell drain 240. This prevents water droplets from accumulating in the snail shell 230 and damaging the ventilation unit 200.

The ventilator 10 may also perform a dehumidification function, and for example, the ventilator 10 may further include an evaporator, a water pan part 520, a condensed water heater 530, and a dehumidification air path.

The evaporator is provided in the casing 100, and absorbs external latent heat by evaporating the heat medium and condenses water vapor in the ambient air to generate condensed water. The evaporator and the ventilation unit 200 are respectively disposed in the two air paths, and the air dehumidified by the evaporator does not pass through the ventilation unit 200. The generated condensed water is heated by a condensed water heater 530 described below to generate steam, and the generated steam is discharged out of the basket 100 through the ventilation unit 200.

The water pan part 520 is disposed below the evaporator and is used for receiving condensed water generated when air passes through the evaporator.

The condensed water heater 530 is used for heating the condensed water in the water receiving tray 520, so that the condensed water is vaporized to generate steam.

The moisture exhaust air passage is used to discharge the steam heated and evaporated by the condensate heater 530 to the ventilation unit 200. In the present embodiment, the exhaust air path 0 is provided upstream of the exhaust air path 300 and communicates with the exhaust air path 300. The ventilation unit 200 is provided in the humidity exhaust path, that is, the steam evaporated by the condensate heater 530 is discharged to the outside of the ventilator 10 through the ventilation unit 200. The ventilation unit 200 discharges the steam to the outside of the enclosure 100.

In this embodiment, the third drain opening 403 is located above the water pan part 520, i.e., the water pan part 520 can be seen by directly viewing the water pan part that is hanging from the third drain opening 403.

Similarly, in this embodiment, the snail shell drain 240 is located above the water pan part 520.

When the ventilation device 10 operates the dehumidification function, the ventilation unit 200 is disposed in the dehumidification air path, that is, the dehumidification air path communicates with the exhaust air path 300. The condensed water in the water receiving tray part 520 is vaporized into high-temperature and high-humidity air having a high relative humidity by the condensed water heater 530, and the air enters the exhaust air duct 300 by the ventilation unit 200, and the high-temperature and high-humidity air forms dew condensation water on the surface of the exhaust air duct 300.

Similarly, the dew condensation water is discharged to the outside of the exhaust air passage 300 through the first water discharge opening 401, the second water discharge opening 402, and the third water discharge opening 403.

Since the third drain port 403 is disposed above the water receiving tray 520, water droplets discharged through the third drain port 403 will drop into the water receiving tray 520 under the action of gravity, thereby preventing the water droplets entering the inner side of the basket 100 from dropping into the room through the air inlet 101, which may cause discomfort to the user.

Similarly, since the snail shell drain 240 is disposed above the water receiving tray 520, water drops discharged from the snail shell drain 240 will drop into the water receiving tray 520, thereby preventing water drops entering the inner side of the basket 100 from dropping into the room through the air inlet 101, which may cause discomfort to the user.

It should be noted that the present invention is not so limited and that the ventilation device 10 may include other functional components to achieve other functions.

In this embodiment, the ventilation device 10 further includes a third drainage protrusion 430.

The third drain protrusion 430 is formed below the bottom wall 422 of the second drain space and extends from one side of the third drain hole 403 to the other side of the third drain hole 403. In this embodiment, the third drain protrusion 430 is formed to extend from the second drain space outer sidewall 462 toward the second drain space inner sidewall 461.

In this embodiment, the third drain protrusion 430 protrudes from the second drain space outer sidewall 462 toward the second drain space inner sidewall 461.

The third drain protrusion 430 has a gap 431 at an end thereof, which communicates with the inside of the housing 100, and is positioned above the water tray part 520.

A description will be given below of a specific embodiment of the ventilation apparatus 10 of the second embodiment, wherein the same process as that of the first embodiment will not be described again.

In this embodiment, the end of the third drain protrusion 430 is disposed above the water receiving tray 520, that is, the gap 431 through which the end of the third drain protrusion 430 communicates with the inside of the basket 100 is located above the water receiving tray 520.

Accordingly, when the water droplets are discharged out of the second drain space 420 through the third drain port 403, the water droplets are dropped onto the third drain projections 430 by gravity, and are discharged into the housing 100 through the gaps 431 provided at the ends of the third drain projections 430.

Since the end of the third drainage protrusion 430 is disposed above the water receiving tray 520, the water drops will drop into the water receiving tray 520 under the action of gravity.

Note that the present invention is not limited thereto, and the drain structure 400 may not include the third drain protrusions 430.

Therefore, the utility model provides a ventilator, wherein the exhaust air duct is provided with a drainage structure for communicating the exhaust air duct and the inner part of the basket body, and the drainage structure can discharge the dew generated by air in the exhaust air duct when the air is cooled from the exhaust air duct to the inner side of the basket body, so as to prevent the dew from dropping outdoors or freezing to form icicles along with the air flow flowing to the outer outlet of the exhaust air duct.

Finally, it should be noted that the above embodiments are only used for illustrating the technical solutions of the present invention, and not for limiting the same; although the present invention has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some technical features may be equivalently replaced; and such modifications or substitutions do not depart from the spirit and scope of the corresponding technical solutions of the embodiments of the present invention.
