Detailed Description

A wall-mounted type air conditioning indoor unit according to an embodiment of the present invention will be described with reference to fig. 1 to 4. Where the orientations or positional relationships indicated by the terms "front," "back," "upper," "lower," "top," "bottom," "inner," "outer," "lateral," and the like are based on the orientations or positional relationships shown in the drawings, the description is for convenience only and to simplify the description, and no indication or suggestion is made that the device or element so indicated must have a particular orientation, be constructed and operated in a particular orientation, and is therefore not to be construed as limiting the invention.

As shown in fig. 1 to 4, a wall-mounted air conditioning indoor unit according to an embodiment of the present invention generally includes a casing 100, an evaporator 900, a fan 800, an air duct 300, and two air outlets, which are an upper air outlet 120 and a lower air outlet 130. The wall-mounted air conditioning indoor unit and an air conditioning outdoor unit (not shown) constitute a vapor compression refrigeration cycle system, and realize cooling/heating of an indoor environment.

The fan is preferably a cross-flow fan 800 having an axial direction extending in a lateral direction (i.e., left-right direction as viewed in fig. 1) for causing air to flow from the evaporator 900 to the upper outlet port 120 or the lower outlet port 130 and then to be blown into the room.

The evaporator 900 is used for exchanging heat with air entering the housing 100 from the air inlet 110 to form heat-exchange air (specifically, cold air during cooling and hot air during heating). Evaporator 900 is preferably a three-section finned evaporator covering the space in front of and above crossflow blower 800.

The top of the housing 100 has an air inlet 110, and the air inlet 110 has an air inlet grille. The lower portion of the front side of the case 100 is provided with an upper outlet 120 and a lower outlet 130. The upper outlet 120 and the lower outlet 130 are arranged in the up-down direction. The upper outlet 120 is provided at an upper side and facing forward, and the lower outlet 130 is opened at a lower side and facing forward and downward. As shown in fig. 1, the housing 100 may be an elongated structure extending in the transverse direction (i.e., left-right direction). The upper outlet 120 and the lower outlet 130 are elongated openings extending in the transverse direction.

An air duct 300 is arranged in the casing 100, an inlet end of the air duct 300 is located at the fan, and an outlet end of the air duct 300 is located at the two air outlets. The air duct 300 is used to guide the heat-exchange air from the evaporator 900 to the air outlet, so that the air is blown out from the air outlet, thereby realizing cooling/heating of the indoor environment.

The front edge of the baffle 500 is pivotally mounted to the housing 100 between the upper outlet 120 and the lower outlet 130, with the pivot axis 510 positioned as shown in fig. 2. The pivot axis 510 extends in a transverse direction.

Fig. 2 to 4 illustrate the wind direction with arrow lines. As shown in fig. 3 and 4, the baffle 500 may be pivoted upward to a downward blowing position in which the rear end of the baffle abuts against the upper wall of the air duct 300 to close the passage from the air duct 300 to the upper outlet 120, so that the air can be blown out from the lower outlet 130 only. As shown in fig. 2, the deflector 500 may also be pivoted downward to an upward blowing position in which the rear end of the deflector abuts against the lower wall of the air duct 300, so as to close the passage from the air duct 300 to the lower outlet 130, and allow the air to be blown out from the upper outlet 120 only.

Further, the lower edge of the upper air outlet 120 extends backward to form the first flow-guiding plate 140, and the surface of the flow-guiding plate 500 extends to form the second flow-guiding plate 520. The length direction of each of the first and second

flow guide plates

140 and 520 extends in the lateral direction. When the baffle 500 is in the aforementioned down-blowing position, the second flow-guiding plate 520 is attached to the lower surface of the first flow-guiding plate 140. When the baffle 500 is in the up-blowing position, the edges of the first and second

flow guide plates

140 and 520 are in contact, as shown in fig. 2, and the ends of the two flow guide plates are in sealing contact. When the guide plate 500 is located at the upward blowing position, the surfaces of the two flow guide plates form a part of the bottom wall of the air duct, so that the air is prevented from directly blowing the inner surface of the shell at the lower edge of the upper air outlet 120, and the air is favorably blown out more smoothly. Meanwhile, the size of the air duct part close to the upper air outlet is reduced, the narrower upper air outlet is conveniently designed, the falling stability of air conditioner transportation is ensured, and the product reject ratio is reduced.

A plurality of wind guide swing vanes 400 are arranged on the upper surface of the first flow guide plate 140. The plurality of wind guide swing vanes 400 are each rotatably installed on the first flow guide plate 140 and arranged in the lateral direction.

Specifically, the air guide swing blade 400 may be disposed adjacent to the upper air outlet 120. When the guide plate 500 is at the upward blowing position, the plurality of guide flaps 400 may rotate synchronously to adjust the left and right air outlet directions of the upper air outlet 120. When the guide plate 500 is located at the downward blowing position, the guide swing vane 400 is located outside the guide plate 500, and the stop work does not work, and the air outlet direction of the lower air outlet 130 is not adjusted. Further, the pivot axis X of each wind guiding swing vane 400 can be inclined forward and extended from top to bottom, so as to facilitate guiding the wind from the upper wind outlet 120 to the front and upward.

In order to realize the air swinging function of the air guide swinging blades 400, a connecting rod can be arranged, each air guide swinging blade 400 is connected with the connecting rod, the connecting rod is driven by a motor to move in a reciprocating manner, and all the air guide swinging blades 400 are driven to swing synchronously in the moving process so as to change the air direction. The driving mechanism of the air guide swing blade is common in the existing wall-mounted air conditioner indoor unit, and is not described herein again.

In some embodiments, as shown in fig. 2 and 3, at least a portion of the first and second flow-

guide plates

140 and 520 can be arc-shaped plate structures with the pivot axis 510 of the flow guide plate 500 as an axis, so that the two can fit closer together during and before and after the flow guide plate 500 pivots, thereby improving the sealing effect.

In some embodiments, the second flow guide plate 520 extends from the width-wise central region 521 of the baffle 500 such that the angle between the second flow guide plate 520 and the baffle 500 is greater, and the flow of wind in the vicinity of the baffle 500 is more gradual when the baffle is in the upwind position.

Specifically, the air duct 300 is composed of an upper volute 320 and a lower volute 310, the inner wall of the lower volute 310 is the lower wall of the air duct 300, and the inner wall of the upper volute 320 is the upper wall of the air duct 300. With the baffle 500 in the aforementioned up-blowing position, the rear end thereof may be made to abut against the front edge of the lower volute 310. The upper volute 320 has a volute tongue 321, and when the guide plate 500 is at the downward blowing position, the rear end of the guide plate abuts against the volute tongue 321, so that after the guide plate 500 and the lower volute 310 form a new air duct together, the upper wall of the new air duct forms a complete volute profile again, the wind direction meets the flow direction requirement of the cross flow fan 800, and the fan efficiency is improved.

In some embodiments, a motor is mounted at the pivot axis of the baffle 500 for driving the baffle 500 to pivot. The motor is preferably a stepping motor capable of rotating forward and backward.

In some embodiments, as shown in fig. 3 and 4, when the baffle 500 is in the aforementioned down-blowing position, the baffle 500 and the lower wall of the wind tunnel 300 are both extended to be gradually inclined downward from back to front, so that the wind is inclined downward from front to front. As shown in fig. 2, when the baffle 500 is in the above-mentioned upward blowing position, the baffle 500 and the upper wall of the air duct 300 are both inclined upward from the rear to the front, so that the wind direction is inclined upward from the front.

In some embodiments, as shown in fig. 1 to 4, a wind deflector 200 is disposed at the lower wind outlet 130. The air guiding plate 200 is configured to be rotatable around a transverse axis to adjust the upward and downward air outlet directions of the lower air outlet 130. In addition, when the flow guiding plate 500 is located at the above-mentioned upward blowing position, the air guiding plate 200 is located outside the flow guiding plate 500, so that when the lower air outlet 130 is not needed for air supply, the air guiding plate 200 seals the lower air outlet 130, as shown in fig. 1 and fig. 2, the bottom appearance of the indoor unit of the air conditioner is more beautiful.

In some embodiments, as shown in fig. 2 to 4, an air outlet grille is disposed at the upper air outlet 120. The upper air outlet 120 is more beautiful due to the arrangement of the air outlet grille. Meanwhile, the air outlet grille can be configured to enable the air to pass through and then be blown obliquely forwards and upwards, so that the air outlet grille has the function of guiding the wind direction.

The wall-mounted air conditioner indoor unit provided by the embodiment of the invention can realize multiple air supply modes:

(1) no blowing mode. As shown in fig. 2, the baffle 500 is in the up-blow position. At the moment, wind is blown out in an upward mode, the user cannot be blown out, the refrigerating/heating performance cannot be influenced, the air supply effect of people cannot be blown out, discomfort caused by direct blowing of the user is avoided, and the wind feeling experience of the user is improved. When the air conditioner is used for refrigerating or heating, the mode of blowing no people can be adopted.

(2) A powerful heating mode. As shown in fig. 3, the baffle 500 is in the down-blowing position, and the air deflector 200 directs the wind downward such that the wind blows straight downward. Because the density of the hot air is low and the hot air has an ascending trend, the hot air is blown downwards as much as possible, and the heating effect can be enhanced.

(3) A forced cooling mode. As shown in fig. 4, the air guide plate 500 is in the downward blowing position, and the air guide plate 200 guides the air forward, so that the air blows forward, and the cold air is blown upward as much as possible due to the sinking tendency of the cold air with high density, thereby enhancing the cooling effect.

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. Accordingly, the scope of the invention should be understood and interpreted to cover all such other variations or modifications.
