It should be noted that the opening of the first valve 132 is proportional to the air output of the first fresh air outlet 131, i.e. the larger the opening of the first valve 132 is, the larger the air output of the first fresh air outlet 131 is. The opening degree of the second valve 142 is proportional to the air output of the second fresh air outlet 141, that is, the larger the opening degree of the second valve 142 is, the larger the air output of the second fresh air outlet 141 is. The wall-mounted air conditioner indoor unit 100 of the embodiment can realize independent air supply control for two fresh air outlets so as to adapt to different working conditions and improve the overall air supply effect.
In a preferred embodiment, as shown in fig. 3, the ventilation system 120 may include: the first motor 133, and the first gear 134 and the first rack 135 engaged with each other, wherein the first rack 135 is fixedly disposed on the first valve 132, and the first motor 133 drives the first gear 134 to rotate, so as to drive the first rack 135 and the first valve 132 to move, thereby changing the opening degree of the first valve 132. As shown in fig. 4, the fresh air system 120 further includes: the second motor 143, and the second gear 144 and the second rack 145 engaged with each other, wherein the second rack 145 is fixedly disposed on the second valve 142, and the second motor 143 drives the second gear 144 to rotate, so as to drive the second rack 145 and the second valve 142 to move, thereby changing the opening degree of the second valve 142. Through the specific arrangement of the motor, the gear and the rack, the opening degrees of the first valve 132 and the second valve 142 can be precisely adjusted, so that the control of the air output of the first fresh air outlet 131 and the second fresh air outlet 141 is more accurate.
As shown in fig. 1 and 2, a diversion arm 116 may be disposed at an interval below the housing 110, an air duct is defined inside the diversion arm 116, and the air duct communicates with the second fresh air outlet 141 when the second valve 142 is opened. The overall length of the drainage arm 116 may be matched to the length of the housing 110 above. According to the situation shown in fig. 1 and fig. 2, the fresh air system 120 is disposed at the left side of the cavity inside the casing 110, and the first air outlet 111 corresponding to the first fresh air outlet 131 is also located at the left side of the top of the casing 110. The second fresh air outlet 141 is located at the lower part of the fresh air system 120, and under the condition that the second valve 142 is opened, the left side of the air duct of the drainage arm 116 is communicated with the second fresh air outlet 141.
In addition, a second air outlet 112 is disposed at the front side of the flow guiding arm 116 for blowing out the fresh air from the second fresh air outlet 141. That is, when the second valve 142 is opened, the fresh air sent from the second fresh air outlet 141 is blown to the internal air passage of the air guide arm 116, and then blown out through the second air outlet 112 on the front side of the air guide arm 116. It should be noted that the front side of the flow guiding arm 116 may be provided with a plurality of second air outlets 112 at the same distance, and the fresh air sent out by the second fresh air outlet 141 may be evenly sent out along the transverse direction of the flow guiding arm 116.
As shown in fig. 2, a third air outlet 113 is formed at a lower portion of the front side of the casing 110 for blowing out the air that has exchanged heat through the heat exchanger. As mentioned above, air entering the cavity, whether it be air of the indoor environment or air of the outdoor environment from the first fresh air outlet 131, may be heat exchanged by the heat exchanger. Then, the air after heat exchange may be the air of the indoor environment entering the cavity, or the air of the outdoor environment entering the cavity through the first fresh air outlet 131 of the fresh air system 120. However, regardless of the source, the heat-exchanged air is always blown out through the third outlet 113.
In a preferred embodiment, the fresh air from the second outlet 112 is mixed with the air from the third outlet 113, which has undergone heat exchange by the heat exchanger, and then sent to the room. Specifically, since the diversion arm 116 and the lower portion of the casing 110 have a certain gap 117, when the third air outlet 113 below the front side of the casing 110 and the second air outlet 112 at the front side of the diversion arm 116 are simultaneously blown, the pressure at the gap 117 is small, so that the air in the indoor environment is forced to be blown forward from the back side of the gap 117, and the mixing of the three air flows is realized. The three air flows are respectively: fresh air from the second outlet 112, air after heat exchange from the third outlet 113, and air from the indoor environment from the gap 117. And the turbulent flow of the three air flows is mixed, so that the wind feeling difference is further reduced, and the air flow of the indoor environment is effectively promoted.
In a specific embodiment, a heat exchange fan (not shown) may be further disposed in the cavity inside the housing 110, and configured to send out the heat exchanged air. As shown in fig. 3 and 4, the fresh air system 120 actually includes a housing 121, and a receiving cavity may be defined inside the housing 121. The accommodating cavity can be internally provided with a fresh air fan which is configured to blow fresh air entering the accommodating cavity to the first fresh air outlet 131 and/or the second fresh air outlet 141. The first and second fresh air outlets 131 and 141 are actually provided at the top and bottom of the casing 121. The fresh air system 120 may be located entirely on either side of the cavity. In a specific embodiment, as shown in fig. 1 and fig. 2, the fresh air system 120 may be disposed at the left side of the cavity, and the first air outlet 111 corresponding to the first fresh air outlet 131 is also disposed at the left side of the top of the housing 110.
In a preferred embodiment, as shown in fig. 3 and 4, an outdoor fresh air inlet 151 is disposed on the rear side of the lower portion of the fresh air system 120, an indoor fresh air inlet 152 is disposed on the front side of the lower portion, and a second fresh air outlet 141 is disposed on the left side of the outdoor fresh air inlet 151 and the indoor fresh air inlet 152. As mentioned above, the fresh air system 120 may be arranged on the left side of the cavity, and fig. 3 shows a view from the left side of the fresh air system 120, while fig. 4 shows a view from the right side of the fresh air system 120. Outdoor air can enter the accommodating cavity of the fresh air system 120 through the outdoor fresh air inlet 151. Indoor air may enter the receiving cavity of the fresh air system 120 through the indoor fresh air inlet 152.
The open and close states of the outdoor fresh air inlet 151 and the indoor fresh air inlet 152 can also be adjusted by the motor. In a specific embodiment, the opening and closing states of the outdoor fresh air inlet 151 and the indoor fresh air inlet 152 can be adjusted by one motor, and when one of the outdoor fresh air inlet and the indoor fresh air inlet is opened, the other is closed. For example, the outdoor fresh air inlet 151 is opened while the indoor intake air inlet is closed; or the outdoor fresh air inlet 151 is closed while the indoor fresh air inlet 152 is opened. In a preferred embodiment, the motors mentioned above can be step motors, so that the opening degree of each air inlet and each air outlet can be precisely adjusted.
In a specific embodiment, when the outdoor fresh air inlet is closed and the indoor fresh air inlet 152 is opened, the first fresh air outlet 131 is closed and the second fresh air outlet 141 is opened. Therefore, when the fresh air fan operates, air in an indoor environment can enter the accommodating cavity through the indoor fresh air inlet 152 and is conveyed to the second air outlet 112 through the second fresh air outlet 141 and the air duct of the drainage arm 116 to be blown out, and indoor air circulation is achieved.
It should be emphasized that, the wall-mounted air conditioner indoor unit 100 of the above-mentioned embodiment can realize independent air supply control for the two fresh air outlets to adapt to different working conditions and improve the overall air supply effect. Because the fresh air entering the fresh air system 120 is only sent out from the first fresh air outlet 131 and the second fresh air outlet 141, the air output of the first fresh air outlet 131 and the air output of the second fresh air outlet 141 can be complemented, that is, the air output of the first fresh air outlet 131 and the air output of the second fresh air outlet 141 can be actually understood as a percentage ratio. For example, in the case that the air output of the first fresh air outlet 131 is 60%, the air output of the second fresh air outlet 141 may be 40%. In the case that the air output of the first fresh air outlet 131 is 80%, the air output of the second fresh air outlet 141 may be 20%.
In some preferred embodiments, the air output of the first fresh air outlet 131 and the second fresh air outlet 141 can be determined according to actual working conditions. For example, the air output of the first fresh air outlet 131 and the second fresh air outlet 141 can be specifically adjusted according to the temperature difference between the indoor environment and the outdoor environment. Specifically, the air output of the first fresh air outlet 131 and the second fresh air outlet 141 can be adjusted according to the absolute value by acquiring a trigger signal for starting the fresh air, detecting the indoor temperature of the indoor environment where the air conditioner is located and the outdoor temperature of the outdoor environment, calculating the absolute value of the difference between the indoor temperature and the outdoor temperature, and adjusting the air output of the air conditioner according to the absolute value.
Since the first fresh air outlet 131 is provided with the first valve 132 controlled to open and close, and the second fresh air outlet 141 is provided with the second valve 142 controlled to open and close, the specific process of adjusting the air output of the first fresh air outlet 131 and the second fresh air outlet 141 according to the absolute value may include: the opening degrees of the first valve 132 and the second valve 142 are changed according to the absolute values to adjust the air output of the first fresh air outlet 131 and the second fresh air outlet 141.
The absolute value of the difference between the indoor temperature and the outdoor temperature may be actually understood as the difference between the indoor temperature and the outdoor temperature, and the difference may have a different magnitude between the indoor temperature and the outdoor temperature regardless of whether the indoor temperature is higher than the outdoor temperature or the indoor temperature is lower than the outdoor temperature. Also, in a case where the outdoor temperature is low, for example, in winter, the wall-mounted air conditioner indoor unit 100 may be in a heating mode, and the air heat-exchanged by the heat exchanger may be hot air. That is, the temperature of the fresh air sent from the first fresh air outlet 131 of the fresh air system 120 will be raised by the heat exchange, and the temperature of the fresh air sent from the second fresh air outlet 141 is lower. In the case of a high outdoor temperature, for example, in summer, the wall-mounted air conditioner indoor unit 100 may be in the cooling mode, and the air heat-exchanged by the heat exchanger may be cool air. That is, the temperature of the fresh air sent from the first fresh air outlet 131 of the fresh air system 120 is reduced by heat exchange, and the temperature of the fresh air sent from the second fresh air outlet 141 is higher. However, no matter which kind of the outdoor temperature is higher or lower, the fresh air sent out through the first fresh air outlet 131 of the fresh air system 120 can exchange heat through the heat exchanger, and the situation that the use experience of the user is influenced by directly sending all outdoor fresh air to the indoor space is avoided.
In a specific embodiment, the specific process of adjusting the air output of the first fresh air outlet 131 and the second fresh air outlet 141 according to the absolute value may include: judging whether the absolute value is smaller than a first preset value or not; and if so, adjusting the air output of the first fresh air outlet 131 and the second fresh air outlet 141 to be 50%. For example, the first preset value is 5 ℃, and if the absolute value of the difference between the indoor temperature and the outdoor temperature is less than 5 ℃ of the first preset value, it can be considered that the temperature difference between the indoor temperature and the outdoor temperature is very small, and the fresh air directly sent out by the second fresh air outlet 141 of the fresh air system 120 is very uniformly mixed with the air subjected to heat exchange for air supply, so that the comfort level of the user is hardly affected. At this time, the air output of the first fresh air outlet 131 and the second fresh air outlet 141 are both adjusted to be 50%, so that the air output of the first fresh air outlet 131 and the air output of the second fresh air outlet 141 are the same.
And under the condition that the absolute value is greater than or equal to the first preset value and smaller than the second preset value, the air output of the first fresh air outlet 131 is adjusted to be a first air output, the air output of the second fresh air outlet 141 is adjusted to be a second air output, wherein the sum of the first air output and the second air output is 100%, the first air output is greater than 50%, and the second air output is smaller than 50%. For example, the second preset value is 10 ℃, the first air output is 60%, and the second air output is 40%. If the absolute value is greater than or equal to the first preset value by 5 ℃ and less than the second preset value by 10 ℃, the temperature difference between the indoor temperature and the outdoor temperature is considered to be small, and the mixed air supply of the fresh air directly sent out by the second fresh air outlet 141 of the fresh air system 120 and the air after heat exchange is slightly uneven, which slightly affects the body feeling comfort level of the user. At this time, the air output of the first fresh air outlet 131 is adjusted to be 60% of the first air output, and the air output of the second fresh air outlet 141 is adjusted to be 40% of the second air output, so that the air output of the first fresh air outlet 131 is slightly larger than the air output of the second fresh air outlet 141.
And under the condition that the absolute value is greater than or equal to the second preset value and smaller than the third preset value, the air output of the first fresh air outlet 131 is adjusted to be a third air output, the air output of the second fresh air outlet 141 is adjusted to be a fourth air output, wherein the sum of the third air output and the fourth air output is 100%, the third air output is greater than the first air output, and the fourth air output is smaller than the second air output. For example, the third preset value is 20 ℃, the third air output is 80%, and the fourth air output is 20%. If the absolute value is greater than or equal to the second preset value by 10 ℃ and less than the third preset value by 20 ℃, the temperature difference between the indoor temperature and the outdoor temperature is considered to be large, and the fresh air directly sent out by the second fresh air outlet 141 of the fresh air system 120 is not uniformly mixed with the air after heat exchange, so that the somatosensory comfort degree of the user is influenced. At this time, the air output of the first fresh air outlet 131 is adjusted to be 80% of the third air output, and the air output of the second fresh air outlet 141 is adjusted to be 20% of the fourth air output, so that the air output of the first fresh air outlet 131 is further greater than the air output of the second fresh air outlet 141.
And under the condition that the absolute value is greater than or equal to the third preset value, the air output of the first fresh air outlet 131 is adjusted to be 100%, and the air output of the second fresh air outlet 141 is adjusted to be 0. If the absolute value is greater than or equal to the third preset value of 20 ℃, the temperature difference between the indoor temperature and the outdoor temperature is considered to be very large, and the fresh air directly sent out by the second fresh air outlet 141 of the fresh air system 120 is mixed with the air after heat exchange to be very uneven, so that the somatosensory comfort degree of a user is greatly influenced. At this time, the air output of the first fresh air outlet 131 is adjusted to be 100%, and the air output of the second fresh air outlet 141 is adjusted to be 0, so that all fresh air entering the fresh air system 120 is sent out from the first fresh air outlet 131, and is sent to the indoor after heat exchange through the heat exchanger.
In a word, under the condition that the temperature difference between the indoor temperature and the outdoor temperature is too large, the air output quantities of the first fresh air outlet 131 and the second fresh air outlet 141 are adjusted, so that the air output quantity of the first fresh air outlet 131 is larger than that of the second fresh air outlet 141, the fresh air after heat exchange is more than the fresh air directly sent out, and the discomfort brought to a user by the air supply temperature difference can be reduced. In addition, no matter what the air output of the first fresh air outlet 131 and the second fresh air outlet 141 are, the fresh air sent out from the first fresh air outlet 131 is always blown out through the third air outlet 113 after heat exchange, the fresh air sent out from the second fresh air outlet 141 is always blown out through the second air outlet 112 of the drainage arm 116, and the air blown out from the second air outlet 112 and the third air outlet 113 is further mixed and then sent to the indoor space. The wind induction difference is effectively reduced by the double measures that one part of fresh air is pretreated by the heat exchanger, and the other part of fresh air is fully mixed with the air before being sent to the room and after heat exchange.
The wall-mounted air conditioner indoor unit 100 of the embodiment can realize temperature adjustment of outdoor fresh air, enables the sensible temperature of a user to be uniform and appropriate, and improves the use experience of the user; independent air supply control is realized for the two fresh air outlets so as to adapt to different working conditions and improve the overall air supply effect; the air supply of the even mixing of outdoor new trend and heat transfer back air can be realized, the poor problem of the wind sense that the uneven mixture caused is avoided, whole air supply volume can effectively be increased simultaneously, further promote user's use and experience.
