Description

Wall-mounted air conditioner indoor unit

Technical Field

The invention relates to the technical field of air conditioning, in particular to a wall-mounted air conditioner indoor unit.

Background

The cold air density tends to sink relatively more and the hot air density tends to rise relatively less. Therefore, the air conditioner needs to blow cold air upward as much as possible during cooling, and needs to blow hot air toward the ground as much as possible during heating, so that the cold air or the hot air is diffused more uniformly in the indoor space, and the cooling and heating speed is higher.

An existing wall-mounted air conditioner indoor unit is generally provided with a forward air outlet, and air guide structures such as an air guide plate and a swing blade are utilized to guide the air outlet direction of air supply airflow so as to realize upward air blowing or downward air blowing.

In the wall-mounted air conditioner indoor unit, an air guide cover plate is arranged outside a casing and comprises an upper guide plate and a lower guide plate. The upper guide plate and the outer peripheral surface of the machine shell define an upper channel which is opened upwards, the lower guide plate and the outer peripheral surface of the machine shell define a lower channel which is opened downwards, and the wall-mounted air conditioner indoor unit can have an upper blowing mode and a lower blowing mode by moving the cover plate up and down. For example, when the air conditioner is cooling, the air guide cover plate may be moved to an upward blowing position where the upper channel is communicated with the air outlet, so that the air flow (for example, cold air, hot air, fresh air, or purified air flow) discharged from the air outlet flows upward along the outer circumferential surface of the casing. In a similar way, when the air conditioner heats, the air guide cover plate can be moved to the lower channel communicated with the air outlet, so that the air supply flow flows downwards along the outer peripheral surface of the machine shell, and the hot air flows downwards along the outer peripheral surface of the machine shell. Because the air supply flow flows along the outer circumference of the casing tightly, the wall attachment effect is formed, and the air supply flow can smoothly reach the roof or the ground along the outer circumference of the casing, so that the wall-mounted air conditioner indoor unit has better refrigerating or heating effect. Meanwhile, the discomfort of human body caused by cold air or hot air blowing can be avoided.

Furthermore, in the wall-mounted air conditioner indoor unit, the upper guide plate can rotate around the lower end of the upper guide plate, and the lower guide plate can rotate around the upper end of the lower guide plate, so that the opening angles of the upper channel and the lower channel can be adjusted, and the air outlet flow, the air outlet speed and the air outlet angle range can be adjusted.

Furthermore, in the wall-mounted air conditioner indoor unit, the lower section of the upper guide plate is in an arc shape, so that the direction change of the air supply flow is more moderate when the air supply flow is blown out from the air outlet and then turns upwards or downwards, and the wind loss and the noise are reduced. Furthermore, the rotating axis of the upper guide plate is collinear with the arc central axis, so that the distance between the outer side surface (arc surface) of the upper guide plate and the lower guide plate is unchanged in the rotating process of the upper guide plate, and the upper guide plate cannot interfere with the lower guide plate. Similarly, the upper section of the lower guide plate is arc-shaped, and the rotating axis of the lower guide plate is collinear with the arc central axis of the lower guide plate, so that the direction of the air supply flow is converted and relaxed, and the interference with the upper guide plate during rotation can be avoided.

Furthermore, the wall-mounted air conditioner indoor unit of the invention enables the front surface of the casing to be a vertical surface, so that the air supply flow can form a wall attachment effect on the front surface of the casing, and can flow upwards or downwards along the front surface of the casing better. In addition, the ratio of the distance between the lower edge of the air outlet and the bottom end of the front surface of the machine shell to the width of the air outlet is larger than 1/2, so that the front surface of the machine shell below the air outlet has enough height, and when the air conditioner operates in a down-blowing mode, the lower channel is longer, the wall attachment effect is more favorably formed, and the air supply airflow is better guided to the right lower side.

The embodiment of the invention provides a wall-mounted air conditioner indoor unit. An indoor unit of a wall-mounted type air conditioner is an indoor part of a split wall-mounted type room air conditioner for conditioning indoor air, such as cooling/heating, dehumidifying, introducing fresh air, and the like.

As shown in fig. 1 to 8, a wall-mounted air conditioning indoor unit according to an embodiment of the present invention may generally include a cabinet 10 and a louver 20.

The casing 10 is provided with an air outlet 12 for discharging the air flow from the casing 10 to the room. The air supply flow can be cold air produced by the wall-mounted air conditioner indoor unit in a refrigeration mode, hot air produced in a heating mode, fresh air introduced in a fresh air mode, purified air produced in a purification mode and the like. The cabinet 10 may be a transversely extending elongated structure as a whole.

The air guide hood panel 20 is disposed outside the outlet 12. The air deflection hood panel 20 includes an upper deflector 21 and a lower deflector 22 arranged in an up-and-down direction. The upper baffle 21 defines an upper passage 212 opened upward with the outer circumferential surface of the casing 10, and the opening angle of the upper passage 212 is rotatably adjusted about the bottom end thereof. Referring to fig. 4, if the upper baffle 21 is rotated forward, its upper end is further away from the cabinet 10 so that its opening angle is increased. In the state of fig. 4, the opening angle of the upper passage 212 is already large. If the upper baffle 21 is rotated backward, the upper end thereof is closer to the cabinet 10, so that the opening angle thereof is reduced. Similarly, the lower baffle 22 and the outer peripheral surface of the casing 10 define a lower channel 222 which is open downward, and the opening angle of the lower channel 222 can be rotatably adjusted around the top end thereof. Referring to fig. 8, if the lower baffle 22 is rotated forward, its bottom end will be further away from the cabinet 10, and the opening angle will increase. In the state of fig. 8, the opening angle of the lower channel 222 is already large. If the lower deflector 22 is rotated backward, the bottom end thereof is closer to the cabinet 10, so that the opening angle thereof is reduced.

The air guide hood plate 20 is mounted on the casing 10 in a vertically movable manner so as to be movable to an upward blowing position where the upper passage 212 communicates with the air outlet 12 to allow the blowing air flow discharged from the air outlet 12 to flow upward along the outer peripheral surface of the casing 10, as shown in fig. 1 to 5. Alternatively, the air guide hood plate 20 is moved to a downward blowing position where the lower passage 222 is communicated with the air outlet 12, so that the blowing air flow flows downward along the outer circumferential surface of the casing 10, as shown in fig. 6 to 8.

Therefore, the wall-mounted air conditioner indoor unit has an upper blowing mode and a lower blowing mode for selection, and the refrigeration and heating effects are obviously improved. For example, when the air conditioner cooling requires the up-blowing mode to be operated, the hood panel 20 is moved to the up-blowing position, as shown in fig. 1 to 4. The air flow (cool air) inside the casing 10 is blocked by the upper baffle 21 after being blown out from the outlet 12, and cannot be directly blown out horizontally, but is blown out upward along the outer peripheral surface of the casing 10. When the air conditioner needs to operate in the down-blowing mode for heating, the air guide cover plate 20 is moved to the down-blowing position, as shown in fig. 5 to 8, so that the air (hot air) cannot be blown out horizontally directly under the blockage of the lower guide plate 22, but flows downward along the outer peripheral surface of the casing 10.

Because the air flow flows upwards or downwards along the periphery of the casing 10, a wall attachment effect (also called as an attachment effect) can be formed, so that the air flow can smoothly reach the roof or the ground along the periphery of the casing 10 to form a shower type air supply effect and a carpet type air supply effect, the refrigeration or heating effect of the indoor unit of the wall-mounted air conditioner is better, and the discomfort of a human body caused by cold air or hot air blowing can be avoided. In addition, in the embodiment of the present invention, the opening angles of the upper channel 212 and the lower channel 222 can be adjusted by rotating the upper baffle 21 and the lower baffle 22, so as to adjust the air outlet flow rate, the air outlet speed, and the air outlet angle range.

Further, the wind deflector panel 20 may be configured to: the air conditioner can be moved to a position (not shown) where both the upper duct 212 and the lower duct 222 are communicated with the outlet 12 (i.e., the air guide cover plate 20 is positioned between fig. 4 and 8) to guide the air flow to supply air to the wall-mounted air conditioner indoor unit in both the upper and lower directions, thereby increasing the air conditioning speed.

In some embodiments, the area of the outer peripheral surface of the casing 10 through which the supply airflow flows may be a flat surface, so as to facilitate the supply airflow to better fit the outer peripheral surface of the casing 10. For example, as shown in fig. 1, in the case where the air outlet 12 is opened at the front side of the casing 10, the front surface of the casing 10, that is, the outer peripheral surface through which the fresh air flows, may be a flat surface.

In some embodiments, as shown in fig. 5, the lower section 210 of the upper deflector 21 is a curved section that gradually bends toward the outlet 12 from top to bottom. The upper section 220 of the lower baffle 22 is a curved section gradually bending from bottom to top toward the air outlet.

When the air guide hood panel 20 is in the upward blowing mode, the rear end of the upper air guide plate 21 may be connected to the lower wall of the air duct 40, referring to fig. 4. Because the rear end of the upper air deflector 21 is a curved section, the inner side surface of the upper air deflector is equivalent to the extension section of the lower wall of the air duct 40, so that the air flow flowing out of the air duct 40 can enter the guide range of the upper air deflector 21 smoothly and with low resistance. Similarly, when the wind deflector panel 20 is in the down-blowing mode, the upper end of the lower wind deflector 22 may be connected to the upper wall of the wind tunnel 40, as shown in fig. 8. Because the upper end of the lower deflector 22 is a curved section, the inner side surface of the lower deflector is equivalent to an extension section of the upper wall of the air duct 40, so that the air flow flowing out of the air duct 40 enters the guide range of the lower deflector 22 smoothly with low resistance.

Further, the bending section of the upper guide plate 21 can be arc-shaped, and the rotation axis x1 of the upper guide plate 21 is collinear with the central axis of the arc-shaped section, so that the distance between the outer surface (arc surface) of the upper guide plate 21 and the lower guide plate 22 is unchanged during rotation, thereby avoiding the interference between the lower end of the upper guide plate 21 and the lower guide plate 22. Similarly, the bending section of the lower guide plate 22 is arc-shaped, and the rotation axis x2 of the lower guide plate 22 is collinear with the central axis of the arc-shaped guide plate, so that the interference between the lower end of the lower guide plate 22 and the upper guide plate 21 during rotation can be avoided.

In some embodiments, as shown in fig. 1 to 8, the front surface of the casing 10 may be a vertical surface (a part of the outer peripheral surface of the casing 10) as a whole, and specifically may be a vertical plane or a curved surface such as an arc surface whose axis extends vertically. The outlet 12 may be opened at a lower portion of the front surface of the cabinet 10. The outlet 12 may be more specifically an elongated shape having a length direction parallel to the transverse direction of the cabinet 10.

Referring to fig. 5, the ratio of the distance (de) from the lower edge d of the air outlet 12 to the bottom e of the front surface of the housing 10 to the width (cd) of the air outlet 12 is greater than 1/2, i.e. de/cd > 1/2, preferably greater than 3/4. Therefore, when the wall-mounted air conditioner indoor unit operates in a down-blowing mode, the front surface of the casing 10 below the lower edge of the air outlet 12 has a sufficient length to guide the air flow to flow downwards, and the coanda effect is improved. In addition, the width (distance from the top to the bottom) of the lower baffle 22 may be greater than the width of the upper baffle 21, that is, the lower baffle 22 is made wider, so as to better guide the airflow to blow down in the downward blowing mode, and compensate for the defect that the guiding distance (i.e., de) of the front surface of the enclosure on the lower side of the air outlet 12 is short.

In some embodiments, as shown in fig. 1 to 8, the wind deflector plate 20 further includes two mounting plates 23 spaced apart from each other, and the two mounting plates 23 are mounted to the casing 10 in a manner of being capable of translating up and down. The upper baffle 21 and the lower baffle 22 are both located between the two mounting plates 23 and are rotatably mounted to the two mounting plates 23, respectively. That is, the air deflection hood panel 20 includes an upper air deflection plate 21, a lower air deflection plate 22, and two mounting plates 23. The upper guide plate 21 and the lower guide plate 22 are mounted on the mounting plates and are specially used for guiding air supply flow, the two mounting plates 23 are movably connected with the casing 10, and a movement driving mechanism is not required to be arranged on the upper guide plate 21 or the lower guide plate 22 to influence air guiding.

Two motors (not shown) may be disposed on one of the mounting plates 23 to respectively drive the upper baffle 21 and the lower baffle 22 to rotate.

Specifically, as shown in fig. 1 to 8, the air outlet 12 may be opened on the front surface of the casing 10. The upper and lower deflectors 21 and 22 are located in front of the outlet 12. Each mounting plate 23 is bent gradually backward from a front side of one lateral end of the cabinet 10 to an end cover 106 of one lateral side of the cabinet 10, and is mounted to the end cover 106 to be able to translate up and down. Thus, a driving mechanism does not need to be arranged on the front side of the casing 10, and the air outlet space is occupied. Each mounting plate 23 has a wind blocking portion 231 extending toward the end cover 106 for blocking the backward flow of the supply air flow to make the supply air flow better flow upward or downward, and to prevent the backward flow from spreading to affect the upward and downward wind forces.

fig. 12 is a schematic exploded view of the structure shown in fig. 11.

As shown in fig. 9 to 12, a rack and pinion mechanism is disposed on at least one end cover 106 of the casing 10 for driving the mounting plate 23 to move up and down, so as to switch the whole wind deflector plate 20 between the up-blowing position and the down-blowing position. Preferably, a rack and pinion mechanism is disposed on each of the two end caps 106 to drive the two transverse ends of the mounting plate 23 to move up or down synchronously, so that the movement is more stable and smooth.

Each of the rack and pinion mechanisms includes a motor 71, a pinion 72 and a rack 73 that mesh with each other. The motor 71 is disposed inside the end cap 106. The gear 72 is mounted on the motor 71, the rack 73 is disposed inside the end cover 106 in a vertically movable manner, and a portion of the rack extends out of the end cover 106 through a vertical strip-shaped offset hole 1061 formed in the end cover 106 so as to be connected with the mounting plate 23. When the motor 71 drives the gear 72 to rotate, the gear 72 drives the rack 73 to translate up and down so as to drive the mounting plate 23 to translate up and down.

Specifically, as shown in fig. 11 to 12, a mounting member 107 may be fixed to an inner wall of the end cap 106. The mounting member 107 is screwed to a plurality of mounting portions 1062 provided on an inner wall of the end cap 106 via a plurality of mounting portions 1072 provided thereon. The mounting 107 is formed with two spaced and vertically extending slide rails 1071. Two sliding grooves 731 having opposite opening directions are formed at both ends of the rack 73 in the width direction, and each sliding groove 731 is matched with one sliding rail 1071 to allow the rack 73 to slide up and down along the mounting member 107. That is, the mount 107 functions to form a slide rail 1071 on which the rack gear 73 is mounted so as to be movable in translation up and down.

A bracket 108 is also secured to the inner wall of the end cap 106 for mounting the motor 71. The rack 73 is sandwiched between the gear 72 and the mount 107, or the gear 72 is located on the side of the mount 107 facing away from the inner wall of the end cap 106. The side of the rack 73 facing the gear 72 is toothed to engage the gear 72 and projects outwardly toward the end cap 106 to form a rib 732, the rib 732 extending out of the end cap 106 through a vertical slot relief hole 1061 and being connected to the mounting plate 23, for example by screws. Specifically, the protrusion 732 may be connected to the wind blocking portion 231. Thus, the wind blocking portion 231 is used for connecting the protruding strips 732 and blocking the airflow, and the design is very ingenious.

In the embodiment, the mounting piece 107 and the bracket 108 are arranged on the inner wall of the end cover 106, so that the main structure of the rack-and-pinion mechanism is mounted on the inner side of the end cover 106, and the appearance of the wall-mounted air conditioner indoor unit is not influenced. And the vertical strip abdicating hole 1061 is formed in the end cover 106 to connect the mounting plate 23 positioned on the outer side of the end cover 106, so that the design is very simple and reasonable.

As shown in fig. 4, the top of the casing 10 is provided with an air inlet 11, an air duct 40 is disposed inside the casing 10, and an outlet of the air duct 40 is communicated with the air outlet 12. A cross-flow fan 50 having an axis extending in a lateral direction is provided at an inlet of the air duct 40. The three-stage heat exchanger 30 surrounds the crossflow blower 50. When the wall-mounted air conditioner indoor unit operates in a cooling mode or a heating mode, indoor air enters the interior of the casing 10 through the air inlet 11, exchanges heat with the three-section heat exchanger 30, is sucked into the air duct 40 by the cross-flow fan 50, and flows to the air outlet 12.

Fig. 9 shows a more specific structure of the wall-mounted type air conditioning indoor unit. As shown in fig. 9, the casing 10 includes a front panel 101, a front lower panel 102, a bottom plate 103, a cover 104, a skeleton 105, and two end caps 106. The front panel 101 and the front lower panel 102 are connected to form the front part of the casing 10, and the outlet 12 is opened in the region where they are connected. The bottom plate 103 constitutes the bottom of the casing 10. The casing 104 and the frame 105 are disposed at the rear side of the front panel 101 to form the air inlet 11 and the air duct 40. The two end caps 106 constitute both lateral end portions of the cabinet 10. A motor 51 is installed at an end of the crossflow blower 50 to drive the crossflow blower 50 to rotate. The motor 51 is mounted on a motor mount 52. An electric cabinet 53 is arranged on one side of the motor base 52 in the transverse direction. The air outlet 12 is provided with a swing blade assembly 60 to adjust the left and right air outlet directions of the air outlet 12. Sensor 80 is installed to horizontal one side top of bottom plate 103 to be used for detecting the indoor condition, thereby according to the indoor condition (detect temperature, human condition etc.), thereby carry out intelligent control to empty regulation control parameter (wind speed, wind direction, temperature etc.).

Of course, the present invention is not limited to the configuration of the cabinet itself and the structure and form of each member inside the cabinet. Namely, the wall-mounted air conditioner indoor unit can also select to adopt heat exchangers, fans and air ducts in other forms.

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.
