Description
Technical Field
The invention relates to the air conditioning technology, in particular to an air conditioner indoor unit.
Background
At present, the air outlet mode of the traditional wall-mounted air conditioner indoor unit is mostly lower air outlet, and a guide plate is usually arranged at the air outlet of the traditional wall-mounted air conditioner indoor unit so as to adjust the air outlet direction of the air outlet through the up-and-down swinging or the left-and-right swinging of the guide plate. However, this method has a limited adjustment range, and it is difficult to achieve a blowing requirement in a wide range. Even if the fluid is blown upwards or laterally by some unconventional means on the basis of the traditional wall-mounted air conditioner indoor unit, the loss of the wind speed and the wind pressure is large, so that the power consumption of the air conditioner indoor unit is high, and the noise is large.
Some indoor units of air conditioners in the prior art are respectively provided with an air outlet at the lower part and the left and right ends thereof, and a fan is arranged in the casing corresponding to each air outlet. The lower part air outlet faces the lower part front side of the casing, and the air outlets at the left end and the right end face the left side and the right side of the casing respectively, so that the air supply effect in a large range is achieved through lower part air outlet and left end air outlet. Although such an air conditioning indoor unit seems to achieve a relatively large air supply range, a wall-mounted air conditioning indoor unit is generally installed on a wall adjacent to a corner in a room, and air supplied through air outlets at left and right ends of the wall-mounted air conditioning indoor unit is generally blown directly onto or away from another wall perpendicular to the wall on which the indoor unit is installed, and both areas do not belong to a normal activity area of a user. Therefore, the actual air supply range of the air conditioning indoor unit is not much different from the air supply range of the conventional air conditioning indoor unit with only the lower air outlet. That is to say, the air conditioner indoor unit not only does not really enlarge the air supply range, but also greatly increases the manufacturing cost and the power consumption because two air outlets are additionally arranged and two fans are additionally arranged. To put it back, even if the installation position of the air-conditioning indoor unit is not considered, the air sent out by the air outlets of the air-conditioning indoor unit is directly blown out towards two opposite directions or mutually perpendicular directions, the air supply ranges of the air outlets are discontinuous and discontinuous, so that the indoor temperature cold and hot are uneven, and the comfort experience of users is seriously influenced.

Referring to fig. 1 to 4, an air conditioning indoor unit 1 according to an embodiment of the present invention includes a casing, a heat exchanger 20, a fan assembly 30, and a first fixed air deflector 41 and a second fixed air deflector 42.
The casing has at least one air inlet, a lower air outlet 111 at a lower portion of the casing, and a first lateral air outlet 112 and a second lateral air outlet 113 at both sides of the casing and facing a lateral front of the casing, respectively. Specifically, the air sent out through the first lateral air outlet 112 and the second lateral air outlet 113 is blown to the lateral front of the casing, the air sent out through the lower air outlet 111 is blown to the lower front of the casing, and the air sent out through each air outlet can directly reach the normal moving area of the user, so that the air supply effect of the left, right and lower surfaces can be achieved, the limitation on the installation position of the air-conditioning indoor unit 1 is weakened, the air supply angle of the air-conditioning indoor unit 1 is increased, and the air supply range of the air-conditioning indoor unit 1 is expanded.
The heat exchanging device 20 is disposed in the cabinet and configured to exchange heat with air flowing therethrough to change the temperature of the air flowing therethrough into cold air or hot air. The fan assembly 30 is disposed in the casing and configured to promote the air heat-exchanged by the heat exchanging device 20 to flow toward the lower air outlet 111, the first lateral air outlet 112 and the second lateral air outlet 113. Specifically, the heat exchange device 20 may be located upstream of the fan assembly 30 in the air flow direction within the enclosure.
The first and second fixed air deflectors 41 and 42 are disposed in the casing and respectively extend from the inside of the casing to the first and second lateral air outlets 112 and 113, so as to guide air flowing from the fan assembly 30 to the first and second lateral air outlets 112 and 113. That is to say, the air-conditioning indoor unit 1 of the present invention employs two curved and extended fixed air deflectors to guide the air to the two side air outlets, which not only enhances the surrounding air supply effect of the air-conditioning indoor unit 1, but also solves the technical problem of large noise in the operation process caused by the movable air deflector employed in the conventional air-conditioning indoor unit, thereby reducing the noise in the overall operation of the air-conditioning indoor unit 1.
In some embodiments of the invention, the enclosure further comprises: a front panel 13 for constituting a front of the cabinet; a rear case 14 for constituting a rear portion of the cabinet; and a first annular portion 151 and a second annular portion 152 for forming the first lateral air outlet 112 and the second lateral air outlet 113, respectively. That is, the first annular portion 151 and the second annular portion 152 are adjacent to both lateral sides of the cabinet, respectively, the interior of the first annular portion 151 defines the first lateral air outlet 112, and the interior of the second annular portion 152 defines the second lateral air outlet 113. The first and second annular portions 151 and 152 may be generally circular, oval, kidney-shaped, or other suitable shapes. Specifically, in the present embodiment, each of the first annular portion 151 and the second annular portion 152 has a substantially elliptical shape, and the major axis thereof extends in the vertical direction.
Further, inner sections of the first annular part 151 and the second annular part 152, which are close to a vertical bisection plane extending in the front-rear direction of the air conditioning indoor unit 1, are respectively connected with edges of two lateral side ends of the front panel 13 in a conformal manner, and outer sections of the first annular part 151 and the second annular part 152, which are far away from the vertical bisection plane, are respectively connected with outer edges of the first fixed air deflector 41 and the second fixed air deflector 42 in a conformal manner. Therefore, the structure of the air-conditioning indoor unit 1 is simplified, and the appearance effect of the air-conditioning indoor unit 1 is enhanced.
Specifically, referring to fig. 1 and 3, the inner section 1511 of the first annular portion 151 located on the left side is connected to the left end edge 131 of the front panel 13 in the same shape, i.e., the inner section 1511 of the first annular portion 151 is connected to the left end edge 131 of the front panel 13 seamlessly, i.e., the shapes of the two are identical and the degree and tendency of bending are the same. The outer section 1512 of the first annular portion 151 on the left side is connected to the outer edge of the first fixed air guiding plate 41 in the same shape, that is, the outer section 1512 of the first annular portion 151 is connected to the outer edge of the first fixed air guiding plate 41 in a seamless manner, that is, the shapes of the two are identical, and the degree and the trend of bending are the same. The inner section 1521 of the second annular portion 152 on the right side is connected to the right end edge 132 of the front panel 13 in the same shape, i.e., the inner section 1521 of the second annular portion 152 is connected to the right end edge 132 of the front panel 13 seamlessly, i.e., the shapes of the two are identical and the degree and tendency of bending are the same. The outer section 1522 of the second annular portion 152 on the right side is connected to the outer edge of the second fixed air guiding plate 42 in the same shape, that is, the outer section 1522 of the second annular portion 152 is connected to the outer edge of the second fixed air guiding plate 42 in a seamless manner, that is, the two are identical in shape and have the same degree and trend of bending.
Specifically, the front panel 13 and the rear housing 14 may be fixed together by means of screw connection or snap connection. In some embodiments of the present invention, the first fixed air deflector 41 and the first annular part 151 may be fixed together by means of screw connection or snap connection; in other embodiments of the present invention, the first fixed air deflector 41 and the first annular portion 151 may be integrally formed. Similarly, the second fixed air deflector 42 and the second annular portion 152 can be fixed together or integrally formed by screwing or clipping.
In some embodiments of the present invention, referring to fig. 2 and 3, the inner section 1511 of the first annular part 151 is more forward than the outer section 1512 of the first annular part 151, so that the first lateral outlet 112 faces the outside front of the cabinet. That is, the inner section 1511 and the outer section 1512 of the first loop portion 151 are at different positions in both the lateral direction and the front-rear direction, the inner section 1511 thereof is closer to a vertical bisecting plane of the air conditioning indoor unit 1 extending in the front-rear direction than the outer section 1512 thereof, and the inner section 1511 thereof is located laterally forward of the outer section 1512, whereby the first lateral outlet port 112 can be directed diagonally outward toward the front of the cabinet.
Further, the second annular portion 152 and the first annular portion 151 are symmetrically disposed, so that the second lateral air outlet 113 and the first lateral air outlet 112 are symmetrically disposed and face the front of the outer side of the housing. That is, the inner section 1521 of the second annular portion 152 is more forward than the outer section 1522 of the second annular portion 151. The inner section 1521 and the outer section 1522 of the second annular portion 152 are located at different positions in the lateral direction and the front-rear direction, the inner section 1521 is closer to a vertical bisecting plane of the air conditioning indoor unit 1 extending in the front-rear direction than the outer section 1522, and the inner section 1521 is located laterally forward of the outer section 1522, so that the second lateral air outlet 113 is directed obliquely outward toward the front of the cabinet.
Therefore, the three air outlets of the indoor air-conditioning unit 1 can form an encircling air supply effect, so that the air supply range of the indoor air-conditioning unit 1 is further expanded, cold air is prevented from directly blowing to a human body, the uniformity of indoor temperature is improved, the comfort level of the indoor air-conditioning unit 1 is improved, and the use experience of a user is better.
Fig. 5 is another schematic cross-sectional view of an air conditioning indoor unit according to an embodiment of the present invention, and fig. 6 is a schematic enlarged view of a portion a of fig. 5. Referring to fig. 3 to 6, in some embodiments of the present invention, the first and second fixed deflectors 41 and 42 each include: the upper edge part is bent and extended forwards from bottom to top and extends along a first curve from inside to outside; the lower edge part is positioned below the upper edge part, is bent and extended forwards from top to bottom and is extended along a first curve from inside to outside; and the plate body part is connected between the rear edge of the upper edge part and the rear edge of the lower edge part and extends along the second curve from top to bottom. The rear edge of the upper edge portion is the lower edge thereof, and the rear edge of the lower edge portion is the upper edge thereof, that is, the plate body portion is connected between the upper edge portion and the lower edge portion, so that the first fixed air guiding plate 41 and the second fixed air guiding plate 42 both extend along a first curve from inside to outside. The first and second fixed air deflectors 41 and 42 having such shapes can effectively guide the flow of air, and thus the air discharged through the lower outlet 111, the first and second lateral outlets 112 and 113 can more easily form a looping type air outlet effect.
It will be understood by those skilled in the art that references to "inner" and "outer" in embodiments of the present invention refer to the interior and exterior of the enclosure, respectively. Meanwhile, since the first and second fixed air deflectors 41 and 42 are each a thin plate-shaped member having a uniform thickness, the shape of the first curve extending by bending from inside to outside can be substantially equal to the shape of the cross section thereof, regardless of the thickness.
Specifically, taking the first fixed air guiding plate 41 as an example, referring to fig. 3 to 6, the first fixed air guiding plate 41 includes an upper edge portion 412, a lower edge portion 413, and a plate portion 414. The upper edge portion 412, the lower edge portion 413, and the plate portion 414 all extend along a first curve 415 from inside to outside, and the plate portion 414 extends along a second curve (not shown) from top to bottom. The shape of the first curve 415 may be the same as or different from the shape of the second curve. Specifically, in the present embodiment, the first curve 415 and the second curve have different shapes. Further, the second curve may include a circular arc-shaped curve protruding rearward.
In some embodiments of the present invention, referring to fig. 6, first curve 415 may include a first circular arc segment 4151, a second circular arc segment 4152, and a third circular arc segment 4153 that are smoothly connected in sequence from inside to outside. The dividing points of two adjacent circular arc segments can be distinguished by the dot-dash line shown in fig. 6. Through deep fluid analysis and a large number of scientific experiments, the designer of the invention finds that the first curve 415 is designed into a curve structure formed by smoothly connecting three sections of circular arcs, so that the resistance of the fluid in the flowing process along the first fixed air deflector 41 can be reduced, the air blown out from the fan assembly 30 can be ensured to flow to the first lateral air outlet 112 more smoothly, the energy loss is reduced, and the air output of the indoor unit 1 of the air conditioner is increased.
Further, the circle centers of the second circular arc segment 4152 and the third circular arc segment 4153 are located at the front side of the first curve 415, and the circle center of the first circular arc segment 4151 is located at the rear side of the first curve 415. That is, the second circular arc section 4152 and the third circular arc section 4153 are both circular arc curves convexly curved rearward, and the first circular arc section 4151 is a circular arc curve convexly curved forward. Further, the radii of the circles on which the third arc segment 4153, the first arc segment 4151 and the second arc segment 4152 are located increase in order. That is, third circular arc section 4153 has a more curved and convex shape than first circular arc section 4151, and first circular arc section 4152 has a more curved and convex shape than second circular arc section 4152. Therefore, the air guided by the first fixed air deflector 41 can be ensured to have a higher speed at the first lateral air outlet 112, and the air guided by the first fixed air deflector 41 can be blown out along the front outside of the casing at the first lateral air outlet 112, so that the air can be blown around in cooperation with the second lateral air outlet 113 and the lower air outlet 111.
Since the second fixed air guiding plate 42 and the first fixed air guiding plate 41 have symmetrical structures, they will not be described in detail herein.
In some embodiments of the invention, the fan assembly 30 may comprise two aft centrifugal fans arranged laterally side by side, i.e. the fan assembly 30 comprises an aft centrifugal fan 31 and an aft centrifugal fan 32. The backward centrifugal fan 31 and the backward centrifugal fan 32 are respectively disposed on a flow path from the heat exchanging device 20 to the first lateral air outlet 112 and the second lateral air outlet 113 in the cabinet. The first and second fixed air deflectors 41 and 42 are located downstream of the backward centrifugal fans 31 and 32, respectively, in the air flow direction in the casing. Therefore, the characteristics of strong anti-static pressure loss capacity and strong air duct matching performance of the backward centrifugal fan can be fully utilized to improve the refrigerating and heating efficiency of the indoor unit 1 of the air conditioner, and further enhance the surrounding air supply effect. Meanwhile, the two backward centrifugal fans are arranged side by side transversely, so that the thickness of the indoor unit 1 of the air conditioner in the front and back directions is reduced, the appearance effect of the indoor unit 1 of the air conditioner is optimized, and the requirement of a user on a small installation space of the indoor unit 1 of the air conditioner is met.
Further, a partition 33 extending vertically is disposed between the two backward centrifugal fans to form two independent air supply ducts respectively communicating one of the backward centrifugal fans 31 and the first lateral air outlet 112, and the other backward centrifugal fan 32 and the second lateral air outlet 113 in the casing. Therefore, the mutual interference of the air sent by the two backward centrifugal fans can be avoided, and the air outlet speed and the air outlet volume of the first lateral air outlet 112 and the second lateral air outlet 113 are improved.
In some embodiments of the present invention, referring to fig. 3 and 4, the rear case 14 has a body 141 extending vertically, and upper and lower edge portions 142 and 143 extending forward from upper and lower sides of the body 141 in a bent manner. The body 141 may be provided with a hanging hole for hanging the indoor unit 1 of an air conditioner on a wall. The number of the air inlets of the indoor unit 1 of the air conditioner may be two, for example, the air inlet 121 and the air inlet 122, and the two air inlets may be respectively disposed on the upper edge portion 142 and the lower edge portion 143 of the rear casing 14 to increase the air inlet volume of the indoor unit 1 of the air conditioner, so as to ensure that the indoor unit of the air conditioner has a larger air outlet volume, and simultaneously, the heat exchange efficiency of the indoor unit 1 of the air conditioner may also be improved. Specifically, the air inlet 121 may be disposed on the upper edge portion 142, and the air inlet 122 may be disposed on the lower edge portion 143. The lower outlet 111 may be formed between the lower edge 143 of the rear case 14 and the lower portion of the front panel 13. Therefore, the indoor unit 1 of the air conditioner can achieve the overall effect of air inlet from top to bottom and air outlet from the left, right and lower sides.
Further, the rear case 14 has a first side flange 144 and a second side flange 145 bent and extended forward from both lateral ends of the body 141. The edge of the first side flange 144 and the outer edge of the first fixed wind deflector 41 are matched with the shape of the outer section 1512 of the first annular part 151, and the edge of the second side flange 145 and the outer edge of the second fixed wind deflector 42 are matched with the shape of the outer section 1522 of the second annular part 152. Specifically, the outer section 1512 of the first annular portion 151 and the outer edge of the first fixed air deflector 41 can both be conformally connected to the lateral side edge of the first side flange 144 of the aft casing 14, and the outer section 1522 of the second annular portion 152 and the outer edge of the second fixed air deflector 42 can both be conformally connected to the lateral side edge of the second side flange 145 of the aft casing 14. This can further simplify the structure of the air-conditioning indoor unit 1 and enhance the appearance of the air-conditioning indoor unit 1.
In some embodiments of the present invention, the heat exchanging device 20 includes a flat plate evaporator disposed at the rear side of the two backward centrifugal fans to improve the heat exchanging efficiency, and reduce the thickness of the indoor unit 1 in the front-back direction, thereby reducing the volume of the indoor unit 1.
In some embodiments of the present invention, referring to fig. 3, the air conditioning indoor unit 1 further includes a first movable air guiding mechanism 51 disposed adjacent to the outlet 311 of one of the backward centrifugal fans 31 and a second movable air guiding mechanism 52 disposed adjacent to the outlet (not shown) of the other backward centrifugal fan 32. Each of the first movable air guiding mechanism 51 and the second movable air guiding mechanism 52 has at least one first movable air guiding plate controlled to rotate in the up-down direction and two second movable air guiding plates controlled to rotate in the front-back direction. Because the first movable air guiding mechanism 51 and the second movable air guiding mechanism 52 are respectively adjacent to the outlets of the two backward centrifugal fans, that is, the two movable air guiding mechanisms are both hidden in the casing, the aesthetic effect of the air-conditioning indoor unit 1 is improved, and the noise generated when the movable air guiding mechanisms operate can be reduced.
Taking the first movable air guiding mechanism 51 as an example, it has a plurality of first movable air guiding plates 511 controlled to rotate in the up-down direction and two second movable air guiding plates 512 controlled to rotate in the front-back direction. Therefore, the air outlet angle of the backward centrifugal fan 31 in the vertical direction can be adjusted by the first movable air deflector 511, and the air outlet angle of the backward centrifugal fan 31 in the front-rear direction can be adjusted by the second movable air deflector 512. Specifically, the two second movable air deflectors 512 are arranged in parallel in the front-rear direction, and the distance between the two second movable air deflectors 512 and the width of the outlet 311 of the backward centrifugal fan 31 in the front-rear direction can be the same, so that all the air blown out from the backward centrifugal fan 31 can be guided by the first movable air guiding mechanism 51 and then sent to the air supply duct where the first fixed air deflector 41 is located. The first movable air guiding mechanism 51 is matched with the first fixed air guiding plate 41, so that the air supply range of the first lateral air outlet 112 can be expanded as much as possible, the surrounding air supply effect of the indoor unit 1 of the air conditioner is improved, and the use experience of a user is further improved. Each second movable air guiding plate 512 is provided with a mounting hole, and the first movable air guiding plate 511 is mounted between the two second movable air guiding plates 512 through the mounting hole.
Since the second movable air guiding mechanism 52 has the same structure as the first movable air guiding mechanism 51, the description thereof is omitted.
It will be appreciated by those skilled in the art that the fan assembly 30 of embodiments of the present invention may also include two forward facing centrifugal fans disposed laterally side by side or a cross-flow fan or axial fans or one or more other suitable fans.
