Detailed Description
The present embodiment provides a wall-mounted type air conditioning indoor unit 100. An air conditioning indoor unit 100 of the present embodiment is described below with reference to fig. 1 to 4. In the following description, as shown in fig. 1 to 3, the directions or positional relationships indicated by "front", "rear", "upper", "lower", and the like are directions with reference to the use state of the air conditioning indoor unit 100.
As shown in fig. 1 to 3, the indoor unit 100 of the air conditioner generally includes a casing 110, a heat exchanger 120 disposed in the casing 110, a volute, and a blower 130 disposed in the volute, wherein the blower 130 may be a cross-flow blower.
The housing 110 is formed with an inlet 110a and an outlet 110 b. Generally, the intake vent 110a is located at the top of the housing 110, and the exhaust vent 110b is located at the bottom of the housing 110. An air outlet duct 150 is defined in the scroll casing to communicate the air inlet 110a with the air outlet 110b, and the air outlet duct 150 has an upper duct wall 152 and a lower duct wall 151.
The heat exchanger 120 is generally located in the air supply path between the air inlet 110a and the air blower 130, and may be configured to exchange heat with air flowing therethrough to change the temperature of the air flowing therethrough into heat exchange air. The blower 130 may be configured to cause indoor air, which is introduced from the air inlet 110a, to flow toward the heat exchanger 120, and to cause heat-exchanged air, which is heat-exchanged by the heat exchanger 120, to flow toward the air outlet 110b via the blower 130 and the air outlet duct 150.
In the present embodiment, as shown in fig. 1, in particular, the upper duct wall 152 includes a bent curved section at the front side, the front end of the bent curved section and the front end of the lower duct wall 151 define an outlet 110b, and the bent curved section is shaped to guide the airflow of the outlet duct 150 downward, so that the airflow blown out from the outlet 110b flows downward. That is, the specific shape of the bent section of the upper duct wall 152 is determined to guide the airflow downward, so that the hot air can flow downward from the air outlet 110b in the heating mode, the temperature rise of the indoor lower space is accelerated, and the heating experience of the user is improved.
In one embodiment, as shown in fig. 1 and 2, the bent section sequentially includes a rear guiding straight section 1521 and a front guiding straight section 1522 from rear to front, the rear guiding straight section 1521 extends upward from rear to front, the front guiding straight section 1522 extends downward from rear to front, and as the front guiding straight section 1522 extends downward as a whole, part of the air flow of the air outlet duct 150 is blown out downward by the guiding of the front guiding straight section 1522, so that heating downward blowing is realized, and the heating effect is enhanced.
The included angle a between the front guiding straight section 1522 and the rear guiding straight section 1521 is 120 ° to 140 °, for example, a may be 120 °, 130 °, 135 °, 140 °, and so on. In this way, the transition of the upper duct wall 152 between the front guide straight section 1522 and the rear guide straight section 1521 is relatively smooth, which is beneficial to smooth flow of the airflow.
In another embodiment, as shown in fig. 3, the curved segment 1525 is an arc protruding upward, and the curved segment 1525 can also guide the airflow downward and make the airflow flow smoother.
As shown in fig. 1-3, the upper airway wall 152 further includes an angled section 1523 located behind the bend and a volute section 1524 that meets the rear end of the angled section 1523. The inclined section 1523 may extend from back to front and downward, so that the airflow smoothly flows to the area defined by the bent section and the lower duct wall 151, and a part of the airflow flows downward out of the indoor unit 100 under the guidance of the bent section.
In order to further improve the air supply comfort, the embodiment further provides a specially designed air deflector 140, and the refrigeration/heating effect is greatly improved through the cooperation of the air deflector 140 and the air outlet duct 150.
Specifically, as shown in fig. 4 in combination with fig. 1 to 3, the air guiding plate 140 is disposed at the air outlet 110b and configured to be controllably rotated around a transversely extending rotating shaft 101 to adjust the airflow direction of the air outlet 110 b.
Specifically, the air guiding plate 140 of the present embodiment includes a main plate section 141 and an extension plate section 142, and the main plate section 141 and the extension plate section 142 may be integrally formed. The main board section 141 has two opposite sides in the width direction, the extension board section 142 is connected to one side of the main board section 141, and the inner wind guiding surface 1421 of the extension board section 142 and the inner wind guiding surface 1411 of the main board section 141 form an angle b, and the angle b is an obtuse angle. Therefore, the air deflector 140 with the bent inner air guide surface is formed, namely, an extension section is added on the basis of the existing air deflector, the total width of the air deflector 140 is increased, the guide path of air flow is prolonged, and the air supply distance is increased; moreover, the extending plate section 142 and the main plate section 141 are arranged at an obtuse angle, so that the wind guiding angle of the wind guiding plate 140 is larger.
As shown in fig. 1, in the heating mode of the indoor unit 100, a part of the hot air is guided by the inner air guide surface of the air guide plate 140 and blown downward, and another part of the hot air is guided by the outer air guide surface of the air guide plate 140 and the front guide straight section 1522 of the upper duct wall 152 and blown downward. Therefore, most of the hot air in the air outlet duct 150 can flow downwards through the specially designed air deflector 140 and the specially designed upper duct wall 152, and the angle of downward blowing of the hot air is increased by combining the special design of the upper duct wall 152, so that the downward air outlet is at a large angle of more than 80 degrees close to the vertical direction, the hot air directly reaches the floor, the lower layer area of the indoor space is rapidly heated, the heating 'foot warming' experience is realized, and the forced heating effect is greatly increased.
In some embodiments, the ratio of the width dimension of the extension plate segment 142 to the width dimension of the main plate segment 141 is 0.13 to 0.17. The width of the extension plate section 142 is designed to be a specific value according to the width of the main plate section 141, so that the overall width of the air deflector 140 is within a reasonable range, the overall width of the air deflector 140 is increased, the air deflecting path is extended, and the influence on the overall aesthetic property of the indoor unit 100 due to the excessive width of the extension plate section 142 is avoided. The inventor of the present application has creatively found that when the ratio of the width dimension of the extension board section 142 to the width dimension of the main board section 141 is 0.15, the air guiding performance of the air guiding plate 140 is optimal, and the air guiding plate 140 does not appear too abrupt when being opened, so as to enhance the visual experience of the user.
In some embodiments, as shown in fig. 4, an angle b between the inner wind guiding surface 1421 of the extension board section 142 and the inner wind guiding surface 1411 of the main board section 141 may be 156 ° to 176 °, so that the overall bending degree of the wind guiding plate 140 is small, and when the indoor unit 100 is cooled, the extension board section 142 can guide more airflow to the front upper side far away from the indoor unit 100, so that the air supply distance is further, and the cooling effect is enhanced. More particularly, the inventor of the present application has creatively found that an angle b formed by the inner wind guiding surface 1421 of the extension plate section 142 and the inner wind guiding surface 1411 of the main plate section 141 is preferably 166 °, and the wind guiding plate 140 with such a design angle has a more significant airflow guiding effect, and the air supply distance is longer, so as to further improve the cooling effect of the indoor unit 100.
Further specifically, as shown in fig. 4, the thickness dimension of the main plate section 141 gradually decreases from the middle position to both side directions in the width direction thereof, that is, the main plate section 141 has a shape that is thick in the middle and thin on both sides in the width direction thereof, thereby increasing the extent to which the middle position of the outer wind guide surface 1412 of the main plate section 141 protrudes outward relative to the inner wind guide surface 1411. As shown in fig. 1 and 3, when the indoor unit 100 having the air guide plate 140 with such a structure heats, the inner air guide surface 1411 of the main plate section 141 guides a part of the hot air blown out from the air outlet 110b downward, and the outer air guide surface 1412 of the main plate section 141 guides another part of the hot air blown out from the air outlet 110b downward, so that the overall air guide effect of the air guide plate 140 is improved, and the hot air downward blowing angle and the amount of the hot air downward blown are increased by the common guide of the outer air guide surface of the air guide plate 140 and the front guide straight section 1522, thereby providing a more comfortable heating experience for the user.
The maximum value d of the thickness dimension of the main plate section 141 may be 5mm to 20mm, that is, the thickness dimension d of the middle position of the main plate section 141 in the width direction thereof is 5mm to 20mm, the thickness is equal to more than 2 times of the thickness of the conventional air deflector, and the main plate section 141 satisfying the design parameter can better guide the hot air downward, and increase the amount of the hot air blown downward.
As shown in fig. 4, the outer wind guide surface 1412 of the main plate segment 141 is a curved surface, and the outer wind guide surface 1422 of the extension plate segment 142 extends in the extending direction of the outer wind guide surface 1412 of the main plate segment 141, that is, the outer wind guide surface 1422 of the extension plate segment 142 extends along the extending direction of the outer wind guide surface 1412 of the main plate segment 141, and the wind guide plate 140, which is overall thick at the middle and thin at both sides, is configured by combining the shape of the main plate segment 141, so as to further increase the wind guide effect of the wind guide plate 140.
As described above, in the indoor heating mode, the air deflector 140 may guide the airflow at the outlet 110b downward. Specifically, the air guiding plate 140 is configured to be controllably rotated around the rotating shaft 101 to a first position as shown in fig. 1 and 3, the whole air guiding plate 140 at the first position is in a downward inclined state, the extending plate section 142 of the air guiding plate 140 at the first position is located above the main plate section 141, and part of the hot air blown out from the air outlet 110b sequentially flows downwards along the inner air guiding surface 1421 of the extending plate section 142 and the inner air guiding surface 1411 of the main plate section 141; part of the hot air flows downward along the outer air guide surface 1422 of the extension plate section 142, and the space between the outer air guide surface 1412 of the main plate section 141 and the front guide straight section 1522 in this order. Therefore, most or even all of the hot air blown out from the outlet 110b can be guided downward by the specially designed air deflector 140 and the specially designed upper air duct wall 152, thereby greatly improving the heating effect.
As described above, in the cooling mode of the indoor unit 100, the air deflector 140 can guide the airflow at the air outlet 110b to the front upper side. Specifically, in the cooling mode of the indoor unit 100, the air deflector 140 can be controlled to rotate around the rotating shaft 101 to a second position as shown in fig. 2, the whole air deflector 140 at the second position is in a horizontal or upward inclined state, and as shown in fig. 2, the whole air deflector 140 is in a substantially horizontal position. The extension plate section 142 is located in front of the main plate section 141, and the extension plate section 142 is in an upwardly tilted state.
Part of the cold air blown out from the air outlet 110b flows forward and upward from the inner air guide surface 1411 of the main board section 141 and the inner air guide surface 1421 of the extension board section 142 in sequence, and due to the fact that the front guide straight section 1522 inclines downward, a small part of the cold air flows forward and downward, while the other part of the cold air can still flow forward and upward along the outer air guide surface 1412 of the main board section 141 and the outer air guide surface 1422 of the extension board section 142 in sequence, more cold air blown out from the air outlet 110b is guided forward and upward, so that the cold air is deflected upwards at a large angle, and then circulates indoors, and shower type refrigeration experience is achieved.
Thus, it should be appreciated by those skilled in the art that while a number of exemplary embodiments of the invention have been illustrated and described in detail herein, many other variations or modifications consistent with the principles of the invention may be directly determined or derived from the disclosure of the present invention without departing from the spirit and scope of the invention.
