Background
In order to achieve a good cooling or heating effect of the air conditioner, people need to close doors and windows when using the air conditioner, and a closed space is formed indoors. However, when air exchange between the indoor and the outdoor is not performed for a long time, the indoor air becomes dirty and the carbon dioxide content in the indoor air is increased.
In order to purify indoor dirty air and reduce the content of carbon dioxide in the indoor air, a fresh air purification module is designed in part of the air-conditioning indoor units, the fresh air purification module can introduce outdoor fresh air into the room to reduce the content of the indoor carbon dioxide, and meanwhile, the fresh air purification module can convey the indoor air to the room after being purified, so that the quality of the indoor air can be improved. In order to be integrated in the shell of the indoor unit of the air conditioner conveniently, only one induced air duct and one induced draft fan are arranged in the fresh air purification module, and outdoor fresh air and indoor air enter the room under the action of the same induced air duct and the induced draft fan, so that the air inlet volume of the outdoor fresh air and the air inlet volume of the indoor air are mutually exclusive. Outdoor fresh air is conveyed into the shell of the indoor unit of the air conditioner from the outside before entering the fresh air purification module, and then is conveyed to the inside of the air conditioner through the fresh air purification module, so that the path from the outdoor fresh air to the inside of the air conditioner is longer, the loss of the outdoor fresh air is larger, the air intake of the outdoor fresh air is smaller, and the content of carbon dioxide in the indoor air cannot be reduced quickly.
Can set up the air door in the inlet air duct of indoor wind, when the content of carbon dioxide in the indoor air is reduced fast to needs, close the air door, the new trend purification module realizes the new trend function alone this moment, draught fan and induced air wind channel only are used for inputing outdoor new trend to the interior, can improve the intake of indoor new trend to can reduce the content of indoor carbon dioxide fast. But the existing air conditioner indoor unit is realized newlyThe room interior airflow direction is seen in figure 1 during wind function, and is mainly through the centrifugal wind channel form in the induced air wind channel formation negative pressure region with outdoor air intake then carry to indoor for indoor formation pressure-fired environment, thereby pass through clearances such as crack, flue with indoor air and discharge to outdoor, thereby realize indoor outer air exchange. However, when the fresh air function is realized in a unidirectional flow mode, if the outdoor atmospheric pressure is constant P, the outdoor air is continuously introduced into the room, and the micro-positive pressure P is formed in the room1＝P+PPositive pressureThe negative pressure formed by the air duct is PAir ductThe resistance to be overcome when outdoor fresh air enters the room is P + PPositive pressure-PAir ductThe resistance that needs to overcome is great for the intake of new trend is littleer, and the new trend effect is not obvious.
In order to increase the fresh air intake and improve the ventilation efficiency, referring to fig. 2, the fresh air can be supplied in a bidirectional flow manner, that is, two independent induced air channels are designed, when the fresh air is supplied, outdoor fresh air is conveyed to the indoor through one induced air channel, and meanwhile, indoor air is conveyed to the outdoor through the other induced air channel, so that the fresh air intake can be obviously improved. However, two air inducing ducts occupy a large space, and it is difficult to design two air ducts due to the limitation of the internal space of the indoor unit of the air conditioner. Meanwhile, when the temperature difference between the indoor part and the outdoor part is large, condensation can be formed at the air flow intersection of the indoor air conditioner unit by the two air ducts, and the normal use of the indoor air conditioner unit is influenced.

The embodiment of the invention provides an air-conditioning indoor unit, which comprises an air-conditioning indoor unit shell and a fresh air purification module 1 arranged in the air-conditioning indoor unit shell, and is shown in figures 3 and 4. Referring to fig. 5 and 6, the fresh air purification module 1 includes a fresh air duct 11, a purification air duct 12, a filter element 15, an induced air duct 13 and an induced draft fan 14 which are arranged in the casing of the indoor unit of the air conditioner; the filter element 15 is arranged in the purification air duct 12 or the induced air duct 13; the induced air duct 13 has a first opening 131 and a second opening 132; the first opening 131 is communicated with the outdoor through the fresh air duct 11; the first opening 131 is also communicated with the indoor space through a purification air duct 12; the second opening 132 communicates with the chamber; the induced draft fan 14 is arranged in the induced draft air duct 13, the induced draft fan 14 can rotate in the forward direction or the reverse direction, and when the induced draft fan 14 rotates in the forward direction, the air flow in the induced draft air duct 13 flows from the first opening 131 to the second opening 132; when the induced draft fan 14 rotates in the reverse direction, the air flow in the induced draft duct 13 flows from the second opening 132 to the first opening 131.
In the embodiment of the present invention, because the first opening 131 of the induced air duct 13 in the fresh air purification module 1 is communicated with the outdoor through the fresh air duct 11, the first opening 131 of the induced air duct 13 is also communicated with the indoor through the purification air duct 12, and the second opening 132 of the induced air duct 13 is communicated with the indoor; therefore, referring to fig. 6, when the induced draft fan 14 rotates in the forward direction, outdoor fresh air enters the induced draft air duct 13 through the fresh draft air duct 11, and is then conveyed indoors through the induced draft air duct 13, so that micro-positive pressure is formed indoors, and indoor air is discharged outdoors through door and window gaps or flues, thereby realizing a fresh air function; meanwhile, under the action of the induced draft fan 14, the indoor air enters the induced draft air duct 13 through the purification air duct 12, and enters the indoor space after being filtered by the purification air duct 12 or the filter piece 15 in the induced draft air duct 13, so that the purification function is realized. Therefore, when the induced draft fan 14 rotates in the forward direction, the fresh air function and the purification function can be simultaneously realized.
When the induced draft fan 14 is rotated reversely, the indoor air enters the induced draft air duct through the purification air duct 12 and the second opening 132, then is conveyed to the fresh air duct 11 through the induced draft air duct 13, and finally the fresh air duct 11 conveys the indoor air to the outdoor, so that the fresh air function can be realized independently when the induced draft fan is rotated reversely. When the fresh air function is independently realized in the embodiment of the invention, part of indoor air is firstly output to the outdoor, so that micro negative pressure is formed indoors, and outdoor fresh air can enter the indoor through gaps such as doors and windows, and the fresh air function is realized. At this time, assuming that the outdoor atmospheric pressure is constant P, the indoor air is continuously discharged to the outside, the outdoor atmosphere is not affected, and the micro negative pressure P is formed in the room2＝P-PNegative pressureNegative pressure P formed by air ductAir ductSo that the resistance received during the process of discharging the indoor wind to the outside is P-PNegative pressure-PAir ductAnd is far less than the resistance to be overcome when outdoor wind is introduced into the room. Therefore, the fresh air purification module 1 in the air-conditioning indoor unit of the embodiment of the invention obviously improves the air intake volume and the air intake efficiency of outdoor fresh air when independently realizing the fresh air function. In the fresh air purification module 1 in the air-conditioning indoor unit provided by the embodiment of the utility model, only one induced air duct is adopted when the fresh air function is realized independently, so that the occupied space of the fresh air purification module 1 can be reduced; and simultaneously, the embodiment of the utility model provides an in fresh air purification module 1 through carry the room air to outdoor fresh air function of realizing, consequently the position that the room air formed the condensation with the contact of outdoor air is in outdoor pipeline department, can not produce the condensation in the induced air wind channel to guarantee fresh air purification module 1's normal operating in the air conditioning indoor set.
There are various structures for connecting the second opening 132 with the room, for example, a shell air outlet 171 is provided on the shell of the air-conditioning indoor unit, and then an air outlet pipe is provided at the second opening 132 of the induced air duct 13, and the air outlet pipe extends out of the shell of the air-conditioning indoor unit from the shell air outlet 171. But because the tuber pipe need occupy extra space, make the embodiment of the utility model provides an in the embodiment of new trend purification module 1's volume increase. Referring to fig. 3, 5 and 6, the embodiment of the present invention provides the second opening 132 of the induced air duct 13 near the casing air outlet 171, and the regulator casing between the casing air outlet 171 and the second opening 132 and the air duct casing 133 of the induced air duct 13 enclose the air outlet duct 17 at this moment, so that the second opening 132 communicates with the outside.
The clean air duct 12 may be formed by various structures, for example, an indoor air inlet 121 is formed on a housing of the indoor unit of the air conditioner, an indoor air duct is connected between the indoor air inlet 121 and the first opening 131, one end of the indoor air duct is communicated with the first opening 131, and the other end of the indoor air duct is communicated with the indoor space. However, the added indoor air pipes occupy extra space, so that the volume of the fresh air purification module 1 is increased, and the difficulty of integrating the fresh air purification module 1 in the shell of the indoor unit of the air conditioner is increased; meanwhile, the indoor air pipe also has larger wind resistance, which can reduce the intake of indoor air. Referring to fig. 3, 5 and 6, the embodiment of the present invention provides an indoor air inlet 121 on the casing of the indoor unit of the air conditioner, the indoor air inlet 121 is communicated with the first opening 131, the purifying air duct 12 is enclosed by the casing of the indoor unit of the air conditioner between the indoor air inlet 121 and the first opening 131 and the air duct casing 133 of the induced air duct 13, no additional component is needed, and the space can be saved; meanwhile, the size of the indoor air inlet 121 is not affected by the internal space of the shell of the indoor unit of the air conditioner, so that the size of the indoor air inlet 121 can be adjusted according to the requirement of the indoor air inlet volume, the air resistance of indoor air during air inlet can be reduced, and the indoor air inlet volume is ensured.
Further, the indoor air inlet 121 is disposed opposite to the first opening 131, at this time, the purifying air duct 12 is shortened, the wind resistance of the indoor air in the purifying air duct 12 is reduced, and the air inlet volume of the indoor air is further ensured.
It should be noted that the purification function is realized by disposing the Filter member 15 in the purification air duct, and the optional Filter member 15 may be any one of an activated carbon Filter screen, a formaldehyde Filter screen, or a HEPA (High efficiency particulate air Filter), or may be a combination of any two or three of the above Filter screens.
The fresh air duct 11 has various structures, for example, a fresh air inlet 111 is formed in the casing of the air-conditioning indoor unit, the fresh air inlet 111 is communicated with the first opening 131, and the fresh air duct 11 is enclosed by the casing of the air-conditioning indoor unit between the fresh air inlet 111 and the first opening 131 and the duct casing 133 of the induced air duct 13. However, since the purifying air duct 12 in the embodiment of the present invention is enclosed by the air conditioner indoor unit casing between the indoor air inlet 121 and the first opening 131 and the air duct casing 133 of the induced air duct 13, the fresh air duct 11 and the purifying air duct 12 partially overlap. If the fresh air duct 11 and the purification duct 12 are partially overlapped, the outdoor fresh air and the indoor air are mixed at the overlapped part of the fresh air duct 11 and the purification duct 12 when air enters, and then enter the induced air duct 13 through the first opening 131. Because outdoor fresh air needs to be transmitted into the fresh air duct 11 from the outdoor when air enters, and the loss of the outdoor fresh air before entering the fresh air duct 11 is large, the wind speed and the wind volume when the outdoor fresh air enters the fresh air duct 11 are both obviously smaller than the wind speed and the wind volume when indoor wind enters the purifying air duct 12, so that the wind volume of the outdoor fresh air in the mixed outdoor fresh air and indoor wind is smaller, and the fresh air entering the indoor is smaller.
In order to make the fresh air duct 11 and the purified air duct 12 independent from each other, referring to fig. 5 and 6, in the embodiment of the present invention, the rear plate member 112 is fixedly connected to the outer wall of the air duct housing 133, and the rear plate member 112 and the outer wall of the air duct housing 133 form a fresh air chamber; the rear plate component 112 is provided with a rear plate air inlet 114 and a rear plate air outlet 115, and both the rear plate air inlet 114 and the rear plate air outlet 115 are communicated with the fresh air cavity; the rear plate air outlet 115 is communicated with the first opening 131, and the rear plate air inlet 114 is used for being communicated with the outdoor.
The embodiment of the utility model provides an in, new trend wind channel 11 includes the new trend chamber, and outdoor new trend passes through back plate air intake 114 and enters into to the new trend intracavity, then carries to induced air wind channel 13 in by back plate air outlet 115 again, and the new trend is not mixed with purifying the wind at the in-process that gets into the wind channel to when realizing new trend function and purification performance simultaneously, guarantee the new trend intake.
In order to communicate first opening 131 with rear panel air outlet 115 and indoor wind gap all, see fig. 5 and fig. 7, the utility model discloses be equipped with curb plate 16 in the air conditioner indoor unit casing of embodiment, first opening 131 department is located to curb plate 16, form the water conservancy diversion chamber in the curb plate 16, curb plate 16 go up open have with first air intake 161, second air intake and curb plate air outlet 163 that the water conservancy diversion chamber communicates, curb plate air outlet 163 with first opening 131 communicates, first air intake 161 with rear panel air outlet 115 communicates, the second air intake with indoor intercommunication.
There are various structures capable of communicating the side plate air outlet 163 with the first opening 131, for example, an air duct is connected between the side plate air outlet 163 and the first opening 131. However, the use of the air pipe increases the wind resistance between the side plate air outlet 163 and the first opening 131, and influences the air intake of outdoor fresh air and indoor air; and the added air pipe also needs to occupy extra space. Referring to fig. 5 and 6, in the embodiment of the present invention, the side plate air outlet 163 of the side plate member 16 is butted with the first opening 131 of the induced air duct 13, so that the side plate air outlet 163 is directly communicated with the first opening 131, the wind resistance between the side plate air outlet 163 and the first opening 131 is reduced, the space occupied between the rear plate member 112 and the air duct housing 133 is also made more compact, and the occupied space of the fresh air purification module 1 is reduced.
The structure that communicates backplate air outlet 115 with first air intake 161 also has the multiple, for example is connected the tuber pipe between backplate air outlet 115 and first air intake 161, but the tuber pipe not only can increase the windage between backplate air outlet 115 and first air intake 161, still can occupy extra space, has still increased manufacturing cost simultaneously. Referring to fig. 5 and fig. 6, in the embodiment of the present invention, the butt joint of the rear plate air outlet 115 of the rear plate component 112 and the first air inlet 161 of the side plate component 16 realizes the communication between the rear plate air outlet 115 and the first air inlet 161, not only does not need to use an additional air pipe, reduces the wind resistance between the rear plate air outlet 115 and the first air inlet 161, and can also make the space between the rear plate component 112 and the side plate component 16 more compact, and reduce the occupied space of the fresh air purification module 1 in the embodiment of the present invention.
Furthermore, the second air inlet 162 is disposed opposite to the indoor air inlet 121, so that the length of the purified air duct 12 can be shortened, and the loss of purified air inlet air can be reduced.
The first air inlet 161 and the second air inlet 162 may be opened on the same side of the side plate 16, or may be opened on different sides of the side plate 16. However, since the indoor air inlet 121 needs to be disposed opposite to the second air inlet 162, if the first air inlet 161 and the second air inlet 162 are disposed on the same side, the second air inlet 162 is also disposed opposite to the indoor air inlet 121, and when the rear plate air outlet 115 of the rear plate 112 is in butt joint with the first air inlet 161 of the side plate 16, the rear plate 112 partially shields the indoor air inlet 121, thereby increasing the wind resistance when the indoor air enters. In order to prevent the indoor air from being influenced by the rear plate member 112, referring to fig. 7, the first air inlet 161 and the second air inlet 162 are opened at different sides of the side plate member 16 in the embodiment of the present invention.
Optionally, the filter element 15 may be disposed in the purification air duct 12, and indoor air is filtered by the filter element 15 in the purification air duct 12 and then enters the indoor space through the induced air duct 13, so as to achieve a purification function; the filtering piece 15 can also be arranged in the induced air duct 13, and because the indoor air and the outdoor fresh air are both passed through the induced air duct 13 and enter into the room, the filtering piece 15 can simultaneously purify the indoor air and the outdoor fresh air, so that the outdoor fresh air input during outdoor air pollution can be purified, and the quality of the indoor air is ensured. However, if the filtering member 15 is disposed in the induced air duct 13, the filtering member 15 needs to extend into the induced air duct 13 and then be connected to the inner wall of the induced air duct 13, which is inconvenient to install. The embodiment of the utility model provides an in filter piece 15 locates curb plate 16's curb plate air outlet 163 department not only can clean room interior wind and outdoor new trend simultaneously, still conveniently filters the equipment of piece 15 simultaneously.
There are various methods to arrange the filter element 15 at the side plate air outlet 163 of the side plate 16, for example, the filter element 15 is fixed on the side plate air outlet 163 of the side plate 16 by screws/bolts, but the filter element 15 is protruded on the side plate 16, so that a gap is easily generated when the side plate air outlet 163 of the side plate 16 is butted with the first opening 131 of the induced air duct 13, which affects the indoor air transportation efficiency.
