Description
Technical Field
The present disclosure relates to a wind mixing structure and a wind supply device using the same.
Background
In some indoor environments, the air quality is poor due to the fact that the ventilation performance is poor and the content of harmful substances such as inhalable particles, ozone and carbon monoxide is high. In order to solve this problem, air supply products capable of sucking fresh air from the outside are available on the market. However, in cold regions such as northeast of China, the outdoor temperature is sometimes as low as minus 20 ℃, so that the air supply products can introduce fresh air from the outside and simultaneously carry out internal circulation on indoor air, so that the temperature of the air blown into the room is not too low. For example, the air blowing device disclosed in patent application publication No. CN 106016481A. As shown in fig. 1, a fan 12, a first filter 13 and a second filter 14 are disposed inside the air supply device, and under the action of the fan 12, indoor air and outdoor air are mixed inside the air supply device to form mixed air, and the mixed air flows into the room after passing through the first filter 13 and the second filter 14.
The outdoor air and the indoor air having a temperature difference may be mixed in the blower device to cause dew condensation. Condensation is a phenomenon in which, when the water vapor in the air reaches a saturated state, the water vapor that is too saturated in the air begins to condense into water and precipitates as the ambient temperature continues to decrease. The critical temperature point at which the water vapor in the air starts to condense is called the condensation point temperature, and when the air temperature is equal to or lower than the condensation point temperature, the air is condensed. In other words, the air having a higher temperature originally can contain a larger amount of water vapor, but when the air meets the other air having a lower temperature, the temperature of the air having a higher temperature decreases, and the water vapor that can be contained decreases, which may cause the water vapor to condense into water and precipitate, resulting in dew condensation. If the temperature is too low, frost will form. Once the mixed air is condensed on the filter screen or the fan, the filter screen loses the function of filtering the air, and the fan is damaged.

Detailed Description
For the purpose of promoting a better understanding of the objects, aspects and advantages of the present disclosure, reference is made to the following detailed description taken in conjunction with the accompanying drawings.
In the present embodiment, a wind mixing structure is provided. As shown in fig. 2 and 3, the wind mixing structure 7 includes: outdoor intake air passage 71, indoor intake air passage 72, outdoor intake opening 711, indoor intake opening 721, and mixture outlet 73. The outdoor intake air passage 71 is provided in plural for dividing the air sucked from the outside. The indoor intake air passage 72 is provided in plural for dividing the air taken in from the room. The outdoor intake air passage 71 and the indoor intake air passage 72 are independent of each other. The plurality of indoor intake air passages 72 and the plurality of outdoor intake air passages 71 are formed in a stacked state, the air mixing structure 7 is formed in a substantially rectangular parallelepiped shape, the outdoor intake opening 711 is formed on one surface of the substantially rectangular parallelepiped shape, the outdoor air is supplied into the outdoor intake air passages, the indoor intake opening 721 is formed on an adjacent surface adjacent to the one surface, the indoor air is supplied into the indoor intake air passages, the mixing outlet 73 is formed on an opposite surface facing the one surface, and the mixing outlet 73 is formed in a stacked state at the downstream end openings 712 of the plurality of outdoor intake air passages 71 and the downstream end openings 722 of the plurality of indoor intake air passages 72.
Before explaining the operation principle of the air mixing structure of the present embodiment in detail, the content of water vapor that can be contained in the air will be explained first. As described in the background, the lower the air temperature, the less water vapor can be contained in the air. The different temperatures of the air and their corresponding saturated water vapour contents are shown in table 1.
When the air taken in from the outdoor air intake opening 711 and the air taken in from the indoor air intake opening 721 contact each other, the temperature of the air (hereinafter, simply referred to as "cool air") having a lower temperature rises due to heat transfer, and the amount of water vapor that can be contained therein becomes large; and the air of higher temperature (hereinafter simply referred to as "warm air") is lowered in temperature, and it can contain less water vapor. If the temperature of the warm air drops to the dew point of the warm air, dew condensation of the warm air occurs. Therefore, as long as the temperature of the cold air is inherently higher than the dew point of the warm air, the temperature of the warm air does not drop to the dew point even if the warm air and the cold air come into contact with each other, and in this case, the mixed air of the warm air and the cold air is not dew even if nothing is done.
On the other hand, when the cold air temperature is equal to or lower than the dew point of the warm air temperature, the ratio of the cold air to the warm air can be adjusted to, for example, 4 by adjusting the ratio of the cold air to the warm air to suppress dew condensation, so that the saturated water vapor content corresponding to the temperature of the mixed air in which the cold air and the warm air are mixed can be made larger than the total amount of water vapor originally contained in the cold air and the warm air.
However, fig. 4 is a fluid analysis diagram when cold air and warm air are introduced into the air mixing structure without any treatment and mixed. As can be seen from the schematic structural diagrams of fig. 2 and 3 and the flow analysis diagram of fig. 4, if the cold air a (white portion shown) and the warm air B (black portion shown) enter the air mixing structure without any treatment, the cold air and the warm air are mixed only in the portion where the cold air a and the warm air B are in contact, and the ratio of the cold air to the warm air in the mixed air C (gray portion shown) is approximately the same, rather than 4. Therefore, the temperature of the mixed air C may be too low, resulting in a saturated water vapor content that is less than the total amount of water vapor that the cold air and the warm air originally contain. That is, the mixed air still causes dew condensation.
Therefore, with the air mixing structure 7 of the present invention, the sucked outdoor air and indoor air are processed, and then both the outdoor air and the indoor air are blown out from the mixing outlet 73 and then enter the mixing part 5 to be mixed.
Fig. 5 is a fluid analysis diagram when cold air and warm air are treated by the air mixing structure 7 and then mixed. As shown in the schematic structural diagrams of fig. 2 and 3 and the flow analysis diagram of fig. 5, the plurality of outdoor intake air passages 71 and the plurality of indoor intake air passages 72 stacked one on another constitute a plurality of groups of mixed air passages, and the cool air a is divided into equal parts by the plurality of outdoor intake air passages 71 of the air mixing structure 7 after entering the air mixing structure 7 from the outdoor intake opening 711, and the warm air B is divided into equal parts by the plurality of indoor intake air passages 72 of the air mixing structure 7 after entering the air mixing structure 7 from the indoor intake opening 721. Therefore, assuming that the ratio of the cool air entering from the outdoor air inlet opening 711 to the warm air entering from the indoor air inlet opening 721 is 4. The multiple sets of cold air and warm air are respectively blown out from the mixing air outlet 73 at a ratio of 4 and then are mixed in contact with each other, the temperature of the mixed air C is high, the saturated water vapor content of the mixed air C is more than or equal to the total amount of water vapor originally contained in the cold air and the warm air, and the water vapor is not separated out from the mixed air, so that the generation of dew condensation is effectively inhibited. Of course, the indoor air intake passages 72 and the outdoor air intake passages 71 do not necessarily have to be stacked on each other, and may be divided into equal parts and stacked on each other before the cool air and the warm air are mixed. That is, the downstream end openings 712 of the outdoor air-intake air passages 71 and the downstream end openings 722 of the indoor air-intake air passages 72 may be formed in a stacked state.
As an embodiment, the present disclosure mounts the air mixing structure 7 in an air supply device with a blower. As shown in fig. 6, the air blowing device of the present embodiment includes: the air mixing device comprises a frame body 1, an outdoor air inlet 2, an indoor air inlet 3, an indoor side air outlet 4, a mixing part 5, a filter screen 6 and an air mixing structure 7.
The housing 1 is box-shaped and forms a casing of the blower.
The outdoor air inlet 2 is disposed on one side surface of the frame 1, and is used for allowing outdoor air to enter the frame 1 and communicate with the outdoor air inlet 711 of the air mixing structure 7.
The indoor air inlet 3 is disposed on an adjacent side surface of the frame body 1 adjacent to the one side surface, and is used for allowing indoor air to enter the frame body 1 and to communicate with the indoor air inlet 721 of the air mixing structure 7.
The indoor outlet 4 is provided on the opposite side surface of the housing 1 opposite to the one side surface, and blows air blown out from the mixing outlet 73 of the air mixing structure 7 into the room.
The fan 10 is provided in the housing 1, and blows air sucked from the indoor air inlet 3 and the outdoor air inlet 2 toward the indoor air outlet 4.
The filter screen 6 is provided in the housing 1 and on the upstream side of the fan 10.
The air mixing structure 7 is arranged in the frame body 1 and is arranged on the upstream side of the filter screen 6.
The space between the air mixing structure 7 and the filter screen 6 forms a mixing section 5 that mixes the air sucked from the outdoor air intake opening 711 and the indoor air intake opening 721 and blown out from the mixing outlet 73.
The air mixing structure 7 is arranged on the upstream side of the filter screen 6, the mixing part 5 is arranged between the air mixing structure 7 and the filter screen 6, and mixed air is uniformly mixed in the mixing part 5 according to a set proportion before entering the filter screen 6, so that the filter screen 6 cannot be dewed or frosted, and the filter screen 6 is ensured to effectively filter air. Through the structure, the condensation can be effectively inhibited, and devices in the air supply device are protected from being damaged.
As shown in fig. 2 and 3, the air mixing structure 7 is formed in a substantially rectangular parallelepiped shape, the outdoor air intake opening 711 is formed in one surface of the substantially rectangular parallelepiped shape, the indoor air intake opening 721 is formed in an adjacent surface adjacent to the one surface, and the mixing outlet 73 is formed in an opposing surface opposing the one surface. That is, after entering the air mixing structure 7 from the outdoor air inlet 711, the air is directly blown out to the mixing outlet 73 opposite thereto; the air enters the air mixing structure 7 from the indoor air inlet 721 and turns to be blown out to the mixing outlet 73. The outdoor air inlet opening 711 and the indoor air inlet opening 721 are located on different surfaces of the air mixing structure 7, so that the outdoor air inlet 2 facing the outdoor air inlet opening 711 and the indoor air inlet 3 facing the indoor air inlet opening 721 are located on different surfaces of the frame body. Because the user is outdoor and indoor when setting up the opening of being connected with outdoor air intake 2 and indoor air intake 3, often can be located the different directions of air supply arrangement and set up outdoor opening and indoor opening, consequently through above-mentioned structure, the pipeline of connecting outdoor opening and air supply arrangement and connecting indoor opening and air supply arrangement can reduce and buckle, and the user of being convenient for carries out the pipe layout.
As shown in fig. 2, 3, 7, 8, and 11, the wind mixing structure 7 is formed by laminating and combining a plurality of divided units 70, and each divided unit 70 includes: a partition plate 701 provided from the outdoor air intake opening 711 toward the mixing outlet 73 in the mounted state of the air mixing structure; an upper protrusion 702 protruding upward from the upper surface of the partition plate 701, facing the indoor air intake opening 721, and extending toward the mixing outlet 73; a lower protrusion 703 protruding downward from the lower surface of the partition plate 701, facing the indoor air intake opening 721, and extending toward the mixing outlet 73; an upper extension portion 704 extending from the top end of the upper protruding portion 702 toward the mixing outlet 73 and forming a flat plate shape; the lower protrusion 703 extends from the tip end thereof to the mixing outlet 73, and forms a flat plate-like lower extension 705.
With the above configuration, in the mounted state of the air mixing structure 7, in the single divided unit 70, the space between the upper extension 704 and the lower extension 705 forms the indoor intake air passage 72, and the upper side of the upper extension 704 and the dividing plate 701 and the lower side of the lower extension 705 and the dividing plate 701 form the outdoor intake air passage 71. That is, in the air mixing structure 7, the indoor intake air passage 72 and the outdoor intake air passage 71 are separated from each other by the upper extension 704, the lower extension 705, and the partition plate 701, and the cold air and the warm air are not mixed with each other before entering the mixing portion 5. By providing the air mixing structure 7 in which the plurality of divided units 70 are stacked and combined in this manner, a plurality of independent indoor intake air passages 72 and outdoor intake air passages 71 are formed.
In the present embodiment, the split unit 70 is made of a heat insulating material, the indoor intake air passage 72 and the outdoor intake air passage 71 are split by a heat insulating material such as a foam material to form the split unit 70, and heat is not transferred between the cold air and the warm air separated by the upper extension 704, the lower extension 705, and the split plate 701 of the split unit 70 before reaching the mixing portion 5, so that the temperature of the warm air is prevented from being lowered to a dew point or less by the heat transfer, thereby suppressing the occurrence of dew condensation.
The upper protruding portion 702 and the lower protruding portion 703 are each formed in an arc shape curved toward the mixing outlet 73 from the indoor air intake opening 721 in the opposite direction. With the above configuration, the indoor intake air passage 72 is formed in an arc shape curved from the indoor intake opening 721 to the mixing outlet 73, and the indoor air flows toward the mixing outlet 73 along the arc-shaped indoor intake air passage 72, so that the pressure loss during air flow can be reduced, and the air volume can be increased.
As shown in fig. 9 and 10, in the mounted state of the air mixing structure, the upper surface of the upper extension portion 704 and the upper surface of the partition plate 701 are provided with first air guiding ribs 706 extending from the outdoor air intake opening 711 to the mixing outlet 73, and the lower surface of the lower extension portion 705 and the lower surface of the partition plate 701 are provided with second air guiding ribs 707 extending from the outdoor air intake opening 711 to the mixing outlet 73. With the above configuration, when the outdoor air is blown out from the outdoor air inlet 711 to the mixed air outlet 73, the first air guide rib 706 and the second air guide rib 707 can perform a rectifying function, that is, a turbulent flow generated when the air flows is reduced, the pressure loss is reduced, and the air volume is increased. On the other hand, the first and second air guiding ribs can increase the strength of the upper and lower extending portions and the partition plate 701, and prevent the upper and lower extending portions and the partition plate 701 from being deformed.
As shown in fig. 7 and 8, in the mounted state of the air mixing structure, the upper protrusion 702 is inclined from the upper end of the partition plate 701 toward the mixing outlet 73, and the lower protrusion 703 is inclined from the lower end of the partition plate 701 toward the mixing outlet 73. With the above configuration, when air is blown out from the outdoor air inlet 711 to the mixing outlet 73 along the partition plate 701, the upper and lower protruding portions, and the upper and lower extending portions, the air can flow more smoothly to the mixing outlet 73 by being guided by the upper protruding portion 702 and the lower protruding portion 703 inclined toward the mixing outlet 73 side, thereby reducing wind resistance and pressure loss and ensuring the air volume.
As shown in fig. 9 and 10, in the mounted state of the air mixing structure, the upward extending portion 704 is inclined downward from the side of the indoor air intake opening 721 toward the side opposite to the side of the indoor air intake opening 721; the lower extension 705 is inclined upward from the indoor air intake opening 721 side to the side opposite to the indoor air intake opening 721 side; the downstream end opening 722 of the indoor intake air passage is formed in a shape that gradually narrows from the side closer to the indoor intake opening 721 toward the side opposite to the indoor intake opening 721. If the upper extension 704 and the lower extension 705 are arranged in parallel with each other, when the indoor air flows from the indoor air intake opening 721 to the downstream end opening 722 of the indoor air intake passage, most of the air flows against the arc-shaped upper protrusion 702 and the arc-shaped lower protrusion 703 after colliding with the upper protrusion 702 and the lower protrusion 703, and then flows out from the side of the downstream end opening 722 of the indoor air intake passage away from the indoor air intake opening 721 (i.e., the side opposite to the indoor air intake opening 721).
By forming the downstream end opening 722 of the indoor intake air passage in a shape that gradually narrows from the side closer to the indoor air inlet opening 721 toward the side opposite to the indoor air inlet opening 721, the wind resistance on the side of the downstream end opening 722 of the indoor intake air passage away from the indoor air inlet opening 721 is increased, more wind is forced to flow out from the side of the downstream end opening 722 of the indoor intake air passage closer to the indoor air inlet opening 721, and the wind distribution in the indoor intake air passage 72 blown out from the downstream end opening 722 of the indoor intake air passage is made more uniform. In this way, the indoor air flowing out of the downstream end opening 722 of the indoor intake air passage and the outdoor air flowing out of the downstream end opening 712 of the outdoor intake air passage can be mixed more uniformly.
In addition, the bottom surface of the air supply device is provided with a water absorption material. Since the upper extension portion 704 is inclined downward from the side of the indoor air intake opening 721 toward the opposite side thereof; the lower extension portion 705 is inclined upward from the side of the indoor air intake opening 721 toward the opposite side thereof; even if dew condensation occurs on the upper extension portion 704 or the lower extension portion 705, the dew condensation may flow down to the bottom surface of the blower along the inclined upper extension portion 704 or lower extension portion 705 and be absorbed by the water absorbent on the bottom surface.
As shown in fig. 6, an outdoor air inlet valve 8 capable of opening and closing the outdoor air inlet 2 is arranged at the outdoor air inlet 2; an indoor air inlet valve 9 capable of opening and closing the indoor air inlet 3 is arranged at the indoor air inlet 3; and the opening degrees of the outdoor air intake valve 8 and the indoor air intake valve 9 can be adjusted by a control part provided in the air blowing device. The control part adjusts the proportion of air entering the air mixing structure 7 from the outdoor air inlet 2 and the indoor air inlet 3 by adjusting the opening degrees of the outdoor air inlet valve 8 and the indoor air inlet valve 9 according to the outdoor temperature and the indoor temperature and humidity.
Through the structure, under the action of the fan of the air supply device, air respectively enters the air supply device from the outdoor air inlet 2 and the indoor air inlet 3 according to the proportion set by the control part. And then enters the air mixing structure through the outdoor air intake opening 711 and the indoor air intake opening 721.
