Detailed Description
Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to like or similar elements or elements having like or similar functions throughout. The embodiments described below by referring to the drawings are illustrative only and are not to be construed as limiting the invention.
The duct assembly 1 of the air treatment apparatus 100 according to the embodiment of the present invention is described below with reference to the accompanying drawings.
As shown in fig. 1 to 3, the duct assembly 1 of the air processing apparatus 100 according to the embodiment of the present invention includes: foam air duct member 11, filter device 12, and heat exchange core 13.
As shown in fig. 3, the foam air duct member 11 may be provided with an indoor air return opening 11a, an indoor air supply opening (not shown), an outdoor fresh air opening 11b and an outdoor air outlet, the foam air duct member 11 may be provided therein with an air return flow path 11d and an air intake flow path 11c, the air return flow path 11d may include an air return inlet air duct 11f and an air return flow air duct (not shown) which are mutually communicated, an inlet end of the air return inlet air duct 11f may be provided with an indoor air return opening 11a, an outlet end of the air return flow air duct may be provided with an outdoor air outlet, the air intake flow path 11c may include an air intake air duct 11e and an air intake flow air duct which are mutually communicated, an inlet end of the air intake air duct 11e may be provided with an outdoor fresh air opening 11b, and an outlet end of the air intake flow air duct may be provided with an indoor air supply opening.
Specifically, outdoor fresh air flow can enter the air inlet flow path 11c through the outdoor fresh air port 11b, and the fresh air flow can circulate in the air inlet air channel 11e and the air inlet circulating air channel in sequence, and the fresh air flow can enter the indoor space through the indoor air supply port. Indoor air flow can enter the return air flow path 11d through the indoor return air port 11a, and can circulate in the return air inlet air duct 11f and the return air circulation air duct in sequence, and then indoor air flow can be discharged into the outdoor space through the outdoor air outlet. Thus, the indoor air and the outdoor air can circulate through the air inlet flow path 11c and the air return flow path 11d in the foam air duct member 11, and the effect of improving the freshness of the indoor air can be achieved.
As shown in fig. 3, a filtering device 12 may be provided in the air intake flow path 11c to filter the fresh air flow. Wherein, the filter device 12 can be a sponge, and the filter device 12 can also be a HEPA net. The filter device 12 can filter out dust, PM2.5 and other impurities in the fresh air flow, so that the cleanliness of the fresh air flow can be improved, and the use experience of a user can be improved.
The heat exchange core 13 may be respectively in communication with the air intake flow path 11c and the air return flow path 11d, the air flows in the air intake flow path 11c and the air return flow path 11d may exchange heat in the heat exchange core 13, the air return inlet duct 11f may be located upstream of the heat exchange core 13 in the air flow direction of the air return flow path 11d, and the air intake duct 11e may be located upstream of the heat exchange core 13 in the air flow direction of the air intake flow path 11 c.
Specifically, the air intake passage 11c and the air return passage 11d may be disposed to intersect along the diagonal line of the foam air duct member 11. The heat exchange core 13 may be used as a heat exchange medium, and the fresh air flow in the air inlet flow path 11c may exchange heat with the indoor air flow in the air return flow path 11d through the heat exchange core 13. Therefore, through the arrangement, the indoor temperature can be kept relatively balanced, and the influence on the indoor average temperature caused by the fact that outdoor fresh air flow directly enters an indoor space can be prevented, so that the use comfort of a user can be improved.
For example, when the outdoor temperature is low, the temperature of the fresh air flow is low, and the temperature of the indoor air flow is high. The fresh air flow can exchange heat with the indoor air flow in the return air flow path 11d through the heat exchange core 13 to raise the temperature of the fresh air flow, so that the average indoor temperature can be prevented from being reduced due to the fact that the fresh air flow enters the indoor space. When the outdoor temperature is higher, the temperature of the fresh air flow is higher, and the temperature of the indoor air flow is lower. The fresh air flow can exchange heat with the indoor air flow in the return air flow path 11d through the heat exchange core 13 to reduce the temperature of the fresh air flow, so that the average indoor temperature rise caused by the fresh air flow entering the indoor space can be prevented, and the use comfort of a user can be improved.
As shown in fig. 3, in the longitudinal direction of the foam air duct member 11 (the left-right direction as shown in fig. 3), the extension length of the outlet end of the air inlet air duct 11e may be B 1, the extension length of the outlet end of the return air inlet air duct 11f may be B 2, and the relationship between the air inlet air duct 11e and the return air inlet air duct 11f may be satisfied: b 1＞B2. The width direction (front-rear direction as shown in fig. 3) of the foam air duct member 11 may be a direction from the inside to the outside, and the length direction of the foam air duct member 11 may be perpendicular to the width direction of the foam air duct member 11.
It will be appreciated that since the filter device 12 is disposed in the air intake passage 11c, the filter device 12 can filter the fresh air flow in the air intake passage 11c, thereby increasing the flow resistance of the fresh air flow in the air intake passage 11 c. Through setting up B 1＞B2, the air current export in the air inlet wind channel 11e is greater than the air current egress opening in the return air inlet wind channel 11f, can reduce the circulation resistance of the fresh air stream in the air inlet flow path 11c from this, thereby ensure that the flow of the air stream in air inlet flow path 11c and the return air flow path 11d remains balanced roughly, can make the operation of air treatment facility 100 more smooth and easy, and then can reduce the noise that the air stream produced when circulating in foam wind channel piece 11.
In the specific example shown in fig. 3, the duct assembly 1 may further include an air intake fan 14 and a return air fan 15. Wherein, the air inlet of the air inlet fan 14 is communicated with the indoor air supply opening of the air inlet flow path 11c, and the air outlet of the air inlet fan 14 is communicated with the indoor space. When the air intake fan 14 works, the air intake fan 14 can rotate to form negative pressure in the air intake flow path 11c, outdoor fresh air flow can enter the air intake flow path 11c and circulate in the air intake flow path 11c under the action of the negative pressure, and fresh air flow can finish filtering and heat exchange when circulating in the air intake flow path 11c and then can enter the indoor space through an air outlet of the air intake fan 14.
The air inlet of the return air fan 15 is communicated with the outdoor air outlet of the return air flow path 11d, and the air outlet of the return air fan 15 is communicated with the outdoor space. When the return air fan 15 works, the return air fan 15 can rotate to form negative pressure in the return air flow path 11d, under the action of the negative pressure, indoor air flow can enter the return air flow path 11d and circulate in the return air flow path 11d, and indoor air flow can exchange heat with fresh air flow when flowing in the return air flow path 11d, and then can enter an outdoor space through an air outlet of the return air fan 15.
The extension length B 1 of the outlet end of the air inlet duct 11e is greater than the extension length B 2 of the outlet end of the air return inlet duct 11f, so that the circulation resistance of the air inlet flow path 11c can be reduced, the working load of the air inlet fan 14 can be reduced, the air inlet fan 14 and the air return fan 15 can be kept rotating at the same speed, working noise generated by the air inlet fan 14 and the air return fan 15 can be reduced, the air output of the air inlet flow path 11c can be increased, and the air treatment efficiency of the air treatment device 100 can be improved.
According to the air duct assembly 1 of the air treatment device 100 of the embodiment of the invention, by setting the extension length B 1 of the outlet end of the air inlet duct 11e to be greater than the extension length B 2 of the outlet end of the air return duct 11f, the circulation resistance of the air inlet flow path 11c can be reduced, thereby not only reducing the working noise of the air duct assembly 1, but also increasing the air output of the air inlet flow path 11c, and further improving the air treatment efficiency of the air treatment device 100.
As shown in fig. 3, according to some embodiments of the present invention, in the length direction of the foam air duct member 11, the inlet end of the air inlet air duct 11e may have an extension length a 1, and the air inlet air duct 11e may satisfy the relationship: a 1/B1 is more than or equal to 0.4 and less than or equal to 0.8. It will be appreciated that when a 1/B1 is too large, i.e. the extension length of the inlet end of the air inlet duct 11e is too long, the air intake of the air inlet duct 11e can be increased, but the structural firmness of the foam duct member 11 is affected, and A1 is too large to meet the assembly requirement of the foam duct member 11. When a 1/B1 is too small, that is, the extension length of the inlet end of the air inlet duct 11e is too short, the difference between the vertical cross-sectional areas of the inlet end and the outlet end of the air inlet duct 11e is too large. When the air inlet fan 14 guides the fresh air flow to circulate in the air inlet flow path 11c, the static pressure loss of the air inlet fan 14 is increased, and the air outlet of the air inlet flow path 11c is greatly reduced. Through the repeated experiments of the inventor, when A 1/B1 is more than or equal to 0.4 and less than or equal to 0.8, the foam air duct piece 11 can meet the assembly requirement, and the air outlet quantity of the fresh air flow in the air inlet flow path 11c can also meet the air outlet requirement of the air duct assembly 1. Further, the air inlet duct 11e may further satisfy: a 1/B1 =3/5.
As shown in fig. 3, according to some embodiments of the present invention, in the length direction of the foam duct member 11, the inlet end of the return air inlet duct 11f may have an extension length a 2, and the return air inlet duct 11f may satisfy the relationship: a 2/B2 is more than or equal to 0.4 and less than or equal to 0.8. It will be appreciated that when a 2/B2 is too large, i.e. the extension of the inlet end of the return air inlet duct 11f is too long, although the air intake of the return air inlet duct 11f can be increased, the structural firmness of the foam duct member 11 is affected, and a 2 is too large to meet the assembly requirements of the foam duct member 11. When a 2/B2 is too small, i.e., the extension length of the inlet end of the return air inlet duct 11f is too short, the difference between the vertical cross-sectional areas of the inlet end and the outlet end of the return air inlet duct 11f is too large. When the return air blower 15 guides indoor air flow to circulate in the return air flow path 11d, the static pressure loss of the return air blower 15 is greatly increased, thereby greatly reducing the air output of the return air flow path 11d and the air treatment efficiency of the air treatment device 100. Through the repeated experiments of the inventor, when A 2/B2 is more than or equal to 0.4 and less than or equal to 0.8, the foam air duct piece 11 can meet the assembly requirement, and the air output of indoor air flow in the return air flow path 11d can also meet the air exhaust requirement of the air duct assembly 1.
As shown in fig. 3, according to some embodiments of the present invention, in the length direction of the foam air duct member 11, the heat exchange core 13 may have an extension length of C, and the air inlet air duct 11e may satisfy: b 1/C is more than or equal to 0.4 and less than or equal to 0.6. It will be appreciated that when the value of B 1/C is too small, the amount of fresh air flowing into the heat exchange core 13 is reduced, which not only reduces the exchange efficiency between indoor air and outdoor air, but also fails to meet the air output requirement of the air treatment apparatus 100. When the value of B 1/C is too large, the air quantity of the fresh air flow entering the heat exchange core body 13 is too large, so that the heat exchange effect between the fresh air flow and the air flow in the return air flow path 11d is affected, the fresh air flow with insufficient heat exchange enters the indoor space, the indoor temperature balance is broken, and the use comfort of a user is affected. When B 1/C is more than or equal to 0.4 and less than or equal to 0.6, the foam air duct piece 11 can meet the air outlet requirement of the air treatment equipment 100, and the fresh air flow can exchange heat with the air flow in the return air flow path 11d in the heat exchange core 13 sufficiently, so that the indoor temperature distribution can be kept relatively balanced. Further, the air inlet duct 11e may further satisfy: b 1/c=0.5.
As shown in fig. 3, according to some embodiments of the present invention, the heat exchange core 13 may have an extension length C in the length direction of the foam duct member 11, and the return air inlet duct 11f may satisfy the relationship: b 2/C is more than or equal to 0.4 and less than or equal to 0.6. It will be appreciated that when the value of B 2/C is too small, the flow rate of the indoor air flow entering the heat exchange core 13 is reduced, so that the heat exchange effect between the fresh air flow and the air flow in the return air flow path 11d is affected, and the insufficient heat exchange of the fresh air flow entering the indoor space breaks the indoor temperature balance, so that the use comfort of the user is affected. When the value of B 2/C is too large, the opening area of the outlet end of the return air inlet air duct 11f is too large, so that the structural firmness of the foam air duct piece 11 is affected, the static pressure loss of the return air fan 15 is increased, and the work load of the return air fan 15 is further increased. When B 2/C is more than or equal to 0.4 and less than or equal to 0.6, the foam air duct piece 11 can meet the heat exchange requirement between indoor air and outdoor air, and can also reduce the work load of the return air fan 15, so that the air output of the return air fan 15 is ensured. Further, the return air inlet duct 11f may further satisfy: b 2/c=0.45.
In a specific example of the present invention, the extension length B 1 of the outlet end of the air inlet duct 11e, the extension length B 2 of the outlet end of the return air inlet duct 11f, and the extension length C of the heat exchange core 13 satisfy: b 1/c=0.5 and B 2/c=0.45. Thus, by the above arrangement, the air flow space in the air inlet duct 11e can be made larger than the air flow space in the air return duct 11f by B 1＞B2, so that the flow resistance of the fresh air flow in the air inlet flow path 11c can be reduced, the work load of the air inlet fan 14 can be reduced, and the work noise of the duct assembly 1 can be reduced.
