As shown in fig. 1 to 3, an air conditioning indoor unit according to an embodiment of the present invention may generally include a casing 10, a movable panel 80, and an air deflector 50.
The housing 10 is provided with an air outlet 12, and the air outlet 12 faces forward and downward (that is, an outlet section of the air outlet 12 faces forward and downward, or a normal of the air outlet 12 gradually inclines downward from back to front). The air flow blown out from the inside of the casing 10 is the supply air flow. When the air conditioner is used for refrigerating, the air supply flow is cold air; when the air conditioner heats, the air supply flow is hot air. Of course, when the air conditioner has a fresh air mode, the supplied air flow can also be outdoor air.
As shown in fig. 1, the indoor unit of the air conditioner may be an indoor unit of an air conditioning system that performs cooling/heating through a vapor compression refrigeration cycle, and specifically may be an indoor unit of a wall-mounted unit, a cabinet unit, or various end machines of a central air conditioner. The indoor unit of the air conditioner may include an evaporator 20, a blower 30, and a duct 40. The evaporator 20 is used for exchanging heat with air entering the housing 10 from the air inlet 11 to form a supply air flow. The inlet of the air duct 40 faces the evaporator 20, and the outlet communicates with the air outlet 12. The fan 30 may be a cross-flow fan disposed at an inlet of the air duct 40 to promote air flow from the evaporator 20 to the air outlet 12.
The movable panel 80 is movably mounted to the housing 10 and configured to be movable to a closed position (fig. 1) located at the front side of the air outlet 12 or to an open position (fig. 2 and 3) away from the front side of the air outlet 12.
The air guide plate 50 is movably attached to the casing 10, and has an air guide surface 511 for mainly contacting and guiding the air flow. The air deflector 50 is configured to: when the movable panel 80 is in the open position, the air deflector 50 can move to the first position, which is located at the lower side of the air outlet 12 and has the air deflecting surface 511 facing upward, so as to guide the blowing air flow forward, forward upward or forward downward, as shown in fig. 2; or to a second position located in front of the outlet 12 so that the air guide surface 511 faces rearward, to guide the air flow downward, as shown in fig. 3.
In the first position, the air deflector 50 may be disposed substantially horizontally with its rear end substantially contiguous with the lower edge of the outlet 12 or with only a small spacing. When the air duct 40 is provided, the air deflector 50 in the first position corresponds to a forwardly extending section of the bottom wall 42 of the air duct to facilitate directing the supply air flow forwardly, as shown in fig. 2. In the second position, the air deflector 50 is disposed substantially vertically with one end thereof substantially contiguous or only slightly spaced from the lower edge of the outlet 12. When the air duct 40 is provided, the air deflector 50 in the first position corresponds to a section of the upper wall 41 of the air duct that is bent downward and extended, so as to facilitate guiding the air flow downward, as shown in fig. 3.
The embodiment of the utility model provides an in, because the machine has set up movable panel 80 and aviation baffle 50 in the air conditioning, it has had multiple air supply mode, has promoted the comfortable nature experience of machine air supply in the air conditioning. For example, during cooling operation of the air conditioner, the movable panel 80 may be selectively adjusted to a first position in which the movable panel is located at an open position away from the front side of the outlet 12 and the air deflector 50 is located at the lower side of the outlet 12, so that the air deflector 50 guides the supply airflow (cold air) forward, upward, or downward. Preferably, the air deflector 50 is selected to guide the cool air to the front upper side, so as to blow the cool air out at a larger upward angle (an included angle between the air flow blowing angle and the horizontal plane) to avoid the human body. The cold wind is scattered downwards after reaching the highest point, and a 'shower type' refrigeration experience is realized, as shown in figure 2. When the air conditioner is in heating operation, the movable panel 80 can be selectively adjusted to the open position, and the air deflector 50 is located at the second position on the front side of the air outlet 12, so that the air deflector 50 guides the air flow (hot air) downward, and the hot air is directly blown to the bottom surface in a manner of approaching to the vertical downward direction, thereby realizing the foot warming experience, as shown in fig. 3.
In some embodiments, the air deflector 50 is further configured to be in a first position to close the air outlet 12 in cooperation with the movable panel 80 when the movable panel 80 is in the closed position, as shown in fig. 1. When the air-conditioning indoor unit is in a shutdown state, the air guide plate 50 and the movable panel 80 close the air outlet 12, so that the appearance of the air-conditioning indoor unit is more overall beautiful.
The air deflector 50 may be manually actuated by a user or actuated by a drive device. The specific motion form of the wind deflector 50 can be rotation or plane motion combining rotation and translation. For example, the outlet 12 and the air deflector 50 may be both elongated with the longitudinal direction parallel to the horizontal direction (the longitudinal direction is perpendicular to the paper surface of fig. 1). The air deflector 50 is rotatably mounted to the housing 10 about a central axis 53 aligned with a longitudinal direction thereof, and when the air deflector 50 is in the first position, the central axis 53 is located above a front section of the air deflector 50, as shown in fig. 2. In this way, the wind deflector 50 rotates clockwise about the central axis 53 by approximately 90 ° and can be changed from the first position to the second position; the change from the second position to the first position is made by a counterclockwise rotation of substantially 90 about its central axis 53, which is a relatively simple actuation.
The movable panel is mounted to the housing so as to be movable up and down. For example, a movable panel may be disposed within the housing, particularly between the front panel of the housing and the evaporator, and the movable panel may be driven by a translational drive (e.g., a motor in conjunction with a rack and pinion mechanism) to translate to the closed position or the open position. However, such a design would make the movable panel occupy a large space inside the casing, and it is very disadvantageous that the thickness (the dimension in the front-rear direction) of the air conditioning indoor unit is increased due to the trend toward the main trend toward a lighter and thinner design of the air conditioning indoor unit.
In the preferred embodiment of the present invention, as shown in fig. 1 and 2, the housing 10 is formed with a receiving opening 13 at the front side thereof for receiving the movable panel 80 in the closed position, as shown in fig. 1. The movable panel 80 is configured to rotate forwardly about its lower end when it is in the closed position so that its upper end is forwardly clear of the upper edge of the receiving opening 13 and then translates upwardly to the open position, as shown in fig. 2. The closing process is the reverse of the opening process. By adopting the special opening mode, the movable panel 80 can be exposed to the outside as a part of the front side panel of the air-conditioning indoor unit, namely, the front surface of the movable panel 80 forms the appearance of the front side part of the air-conditioning indoor unit, as shown in fig. 1. The advantage of this design is that the movable panel 80 is not required to be mounted inside the housing 10 to move up and down, occupying the space inside the housing 10 which is a local constraint; on the other hand, the movable panel 80 has a strong ornamental value in the opening movement, so that the appearance of the air-conditioning indoor unit is very attractive, and the modern feeling and the technological feeling of the air-conditioning indoor unit are improved.
Specifically, a rotation driving device (e.g., a stepping motor) for driving the movable panel 80 to rotate around the lower end thereof and a translation driving device for driving the movable panel 80 to translate upward may be disposed in the housing 10, or other moving mechanisms may be employed to realize the above-mentioned compound movement of the movable panel 80. These drive devices are well known in the field of household appliances and machines, and will not be described in further detail herein.
Fig. 4 is a schematic structural view of a wind deflector 50 in the indoor unit of the air conditioner shown in fig. 1; fig. 5 is a schematic size relationship diagram of the wind deflector 52 and the wind deflector body 51 of the wind deflector 50 shown in fig. 4.
In some embodiments, as shown in fig. 4, the wind deflector 50 may include a wind deflector body 51 and a wind-raising portion. The air deflector body 51 is a main body of the air deflector 50, and is mounted to the casing 10 for movable connection with the casing 10. When the air deflector 50 is in the first position (see fig. 2), the upward surface of the air deflector body 51 forms the air guiding surface 511, which is mainly used for guiding the blowing air flow. The wind blowing part is formed on the wind guide surface 511, and is used for guiding the air supply flow to obliquely flow upwards when the wind deflector 50 is at the first position, so that the blowing angle of the air supply flow is increased, and cold wind is blown upwards at an angle closer to the vertical direction when the air conditioner is used for refrigeration.
As shown in fig. 4, the wind-lifting portion may include a wind-lifting plate 52 spaced apart from the wind-guiding surface 511. When the air deflector body 51 is in the first position, the forward and backward ends are respectively the first end (end a) and the second end (end B), as shown in fig. 2. In a direction from the second end to the first end (a direction from the end B to the end a, which is a flowing direction of the blowing air flow when the air deflector 50 is at the first position), the distance between the air deflector 52 and the air deflecting surface 511 gradually increases to smoothly guide the air flow away from the air deflector body 51. Moreover, since the wind-lifting plate 52 and the wind-guiding plate body 51 are arranged at an interval, when the wind-guiding plate 50 is at the second position, even if some air flow is wound around the front end of the wind-lifting plate 52, the air flow can enter the space between the wind-lifting plate 52 and the wind-guiding plate body 51 under the guidance of the wind-lifting plate 52 and then continuously flow downwards, as shown in fig. 3, without escaping to the front side of the wind-guiding plate body 51, so that the air flow cannot be blown out downwards better.
As shown in fig. 4, it is preferable that the air deflector 52 is provided at the first end (end a) of the air deflector body 51 to perform a focused upward guide of the blowing air flow when the blowing air flow is near to leave the air deflector 50, and to blow upward. In addition, the projection of the end (E end) of the wind-raising plate 52 far from the second end on the wind guide plate body 51 can be made to fall outside the wind guide surface 511. In other words, the air outlet end (a end) of the air deflector body 51 is retracted to the second end (B end) of the air deflector body 51 by a distance compared with the end (E end) of the air raising plate 52. It can also be understood that the end of the wind-raising plate 52 is perpendicular to the wind-guiding surface 511 of the wind-guiding plate main body 51, and the hanging part falls on the extension surface of the wind-guiding surface 511. This makes the wind-raising plate 52 more protrusive with respect to the wind deflector body 51, facilitating wind raising thereof at a larger angle.
The wind-lifting portion may further include a connecting rib (not shown), and the connecting rib is connected between the wind deflector body 51 and the wind-lifting plate 52 to realize the structural connection therebetween. The wind-raising portion and the wind deflector body 51 may be an integrally formed integral piece.
The embodiment of the utility model provides a carry out optimal design through size relation and the relative position relation to the board 52 and the aviation baffle body 51 of raising the wind, make it have better effect of raising the wind. Fig. 5 is a schematic size relationship diagram of the wind deflector 52 and the wind deflector body 51 of the wind deflector 50 shown in fig. 4.
As shown in fig. 5, the wind-lifting plate 52 may include a plate main body section 521 and an arc-shaped section 522 connected to an end of the plate main body section 521 closer to the wind deflector body 51 and having a convex surface facing the wind deflector body 51, wherein the arc-shaped section 522 is smoothly connected to the plate main body section 521 for smoothly guiding the supply air flow to the plate main body section 521, and the supply air flow is lifted and guided by the plate main body section 521.
As shown in fig. 5, the width (ED end distance) of the wind-raising plate 52 and the width (L) of the wind deflector body 51 can be set1) The ratio of the first to the second is between 0.3 and 0.35, preferablyIs chosen as 1/3. A width (L) of a portion of the wind guide surface 511 outside the wind guide surface 511 projected by the wind raising plate 522) Width (L) of the air deflector body 511) The ratio of the two is between 0.08 and 0.12, preferably 0.1. The wind-raising angle θ (the included angle between the flowing direction of the supplied air after being blown out from the wind-raising plate 52 and the flowing direction of the supplied air before flowing into the surface of the wind-raising plate 52) of the wind-raising plate 52 is preferably 25 ° to 35 °, so as to ensure that the supplied air has a better wind-raising effect and avoid excessive wind resistance caused by an excessive wind-raising angle of the wind-raising part.
In some embodiments, as shown in fig. 2 and 4, the other side 512 of the air deflector body 51 facing away from the air deflecting surface 511 may be formed with a streamlined projection 5121 at a section adjacent to the first end (a end). When the air deflector 50 is at the first position, part of the air supply airflow flows out forward from between the upper side of the air deflector body 51 and the air raising plate 52, and the normal temperature air at the lower side of the air deflector body 51 can be converged into the air supply airflow under the drive of the negative pressure action of the air supply airflow and the guide of the streamline convex part 5121, so that a certain air mixing effect is formed, the air supply amount is increased, the temperature of the part of the airflow is closer to the room temperature, and the human body feeling is more comfortable. As previously mentioned, the air conditioning indoor unit may include the duct 40. The air duct 40 is connected to the air outlet 12 inside the housing 10, and is used for guiding the air flow to the air outlet 12.
In the embodiment of the present invention, the air deflector 50 has a multi-stage wind raising effect when being in the first position. Specifically, the surface (upper surface in this state) of the wind-lifting plate 52 departing from the wind deflector body 51 forms a wing surface structure with a large elevation angle, the airflow stably flows after being accelerated by the fan, when passing through the wind-lifting plate 52, the upper airflow is accelerated to lift, the lift force is rapidly increased, the flow velocity of the whole airflow is increased, the upward blowing angle is increased, a higher wind-lifting angle and speed can be rapidly reached within a very short distance, and first-stage wind lifting is formed (the first-stage wind lifting process is similar to the take-off process of a carrier aircraft which performs sliding takeoff on an aircraft carrier). The extended profile of the wind-lifting plate 52 can be made into an archimedes spiral to enhance the first-stage wind-lifting effect. A passage gradually expanding along the airflow direction is formed between the wind-raising plate 52 and the wind deflector body 51, and the inlet of the passage is narrow, so that the airflow enters at high speed. The passage area is gradually increased to minimize the resistance when the air flow passes through, and the high air speed is still maintained after the air flow passes through. Meanwhile, the air outlet angle gradually rises under the action of the surface (lower surface) of the air deflector 52 facing the air deflector body 51, so that the middle-layer high-speed airflow further rises to blow out the channel to form second-level air blowing. After the air flow passes through the first stage wind raising and the second stage wind raising, a negative pressure region is formed at the lower side of the air deflector body 51. The lower outlet air flow is sucked by negative pressure, changes direction, deflects upwards along the air deflector body 51, and is converged with the high-speed high-pressure air flow at the middle layer to form integral injection polymerization air flow. The upward movement of the lower layer airflow forms third-level wind raising. Through the three-level air raising effect, the air blowing flow on the refrigeration gradually advances and rises layer by layer to form the integral large-angle air raising effect.
Fig. 6 is a schematic shape view of the upper wall 41 of the air duct of the air conditioning indoor unit shown in fig. 1.
In some embodiments, as shown in fig. 6, the upper wall 41 of the air duct 40 includes a front flat plate section (ab section) extending rearward from the upper edge of the air outlet 12, a curved plate section (bc section) extending rearward from the rear end of the front flat plate section (ab section), a rear flat plate section (cd section) extending upward rearward from the rear end of the curved plate section (bc section), an arc-shaped transition section (de section) extending upward from the rear end of the rear flat plate section (cd section) first rearward, and an upper flat plate section (ef section) extending upward from the upper edge of the arc-shaped transition section (de section). By specially designing the shape of the upper wall 41 of the air duct 40, the rear flat plate section (cd section) close to the fan 30 is a straight line section, which is beneficial to keeping the air outlet stability of the fan. The middle arc plate section (bc section) can enlarge the air outlet angle, change the air outlet direction and increase the air outlet quantity under the condition of minimum flow resistance. The outermost section of the upper wall 41 of the air duct is a front panel section (ab section), which can be horizontal and also has a certain upward inclination angle, so that the air outlet flow is stable, and the flowing directivity is better. The design of the shape of the upper wall 41 of the air duct enables the air quantity and the air flow stability to be better when the air flow is blown upwards.
