The invention provides a refrigerating air conditioner indoor unit, an air guide plate structure thereof and an air guide control method of the refrigerating air conditioner indoor unit, which solve the problem of air guide of the air guide plate structure of the existing refrigerating air conditioner indoor unit.
Hereinafter, a product and the like will be described in detail through a basic design, an extended design, and an alternative design.
An air deflector structure of a refrigeration air conditioner indoor unit is suitable for the air conditioner indoor unit, the air conditioner indoor unit is provided with an air inlet 7 and an air outlet, air enters the air conditioner indoor unit from the air inlet 7 and is discharged from the air outlet, and the air flowing path forms an air passage. In order to make more wind flow out according to the required direction, the air deflector structure is arranged in the air flue. As shown in fig. 2-8, the air deflector structure includes a fixed air guide strip 1 and a movable air guide strip 2 disposed inside an air outlet of an air conditioner indoor unit; the fixed air guide strip 1 is fixed on the inner wall of the air duct; a groove with an opening facing the air outlet end is formed in the fixed air guide strip 1, the movable air guide strip 2 can be arranged in the groove in a sliding mode, and the movable air guide strip 2 slides out of or into the groove under the action of the first driving mechanism; the lower surfaces of the fixed air guide strips and the movable air guide strips are convex cambered surfaces, and the lower bottom surfaces of the grooves are convex cambered surfaces.
The term "inside the outlet" refers to the air being exhausted from the outlet, wherein the air is exhausted from the inside of the outlet to the outside of the outlet. Of course, it can also be said that, with respect to the air conditioner indoor unit, the inside of the air outlet refers to the internal space of the air conditioner indoor unit near the air outlet, and the outside of the air outlet refers to the external space of the air conditioner indoor unit near the air outlet. The fixed air guide strip 1 is fixed in an air duct of an air conditioner indoor unit through a fixed pin shaft 11, and the position is not changed. In some embodiments, the fixed wind guide strips can be connected with the air outlet frame of the chassis 9.
The movable air guide strip is arranged inside the fixed air guide strip, the movable air guide strip can slide out of the fixed air guide strip when the air guide is required to be prolonged or the air guide direction is required to be changed, the trend of the movable air guide strip is different from the trend (or the extending direction) of the fixed air guide strip by virtue of the rotating direction of the movable air guide strip, and the direction of air flow can be changed by the movable air guide strip. Such as:
in the first case, as shown in fig. 3 and 6, the movable air guide strip 2 is arranged in the groove of the fixed air guide strip 1, the fixed air guide strip plays a role of main air guide, if the movable air guide strip is partially arranged outside the fixed air guide strip, the air guide can be assisted, the length of the air guide is increased, under the condition, the length of the air guide strip is prolonged equivalently, the air guide distance can be increased, and the air guide strip is suitable for conventional refrigeration air guide.
In the second case, as shown in fig. 4 and 7, the movable air guide strip 2 slides out of the fixed air guide strip 1 and slides upward along the arc with the upward opening, and in this case, the movable air guide strip 2 guides the air guided by the fixed air guide strip 1 upward, and changes the flow direction of the air to the upward direction. The air conditioner is suitable for blowing air to a ceiling, and the feeling of people in a refrigeration environment is improved by virtue of natural falling of cold air.
The extension line refers to the direction of the wind guide strip, and cannot be understood as the wind guide strip is extended. The movable air guide strip 2 is closer to the air outlet relative to the fixed air guide strip 1, air entering from the air inlet 7 is guided through the fixed air guide strip 1, and then air is guided through the movable air guide strip 2. The structure can meet different air guide modes under the conditions.
As shown in fig. 5 and 8, the first drive mechanism includes: a sliding shaft 102, a rotating shaft 103, and a driving motor 104; the movable wind guide strip 2 is provided with connecting shafts 101 at two ends respectively, the connecting shafts 101 are fixed on mounting parts 1021 of the sliding shafts, the mounting parts 1021 are installed in sliding grooves 1031 of the rotating shafts in a sliding mode, the rotating shafts 103 are further provided with shaft mounting parts, and the shaft mounting parts are installed on the driving motors 104.

The central line track of the guide sliding groove is the same as the motion track of the movable wind guide strip. The movable air guide strips are guided to slide downwards by the guide sliding grooves to form a downward extending mode. The guide sliding groove is an upper opening arc and guides the movable air guide strip to rotate upwards.
Under the action of the driving motor, the rotating shaft drives the sliding shaft to start sliding along the guide sliding groove 91, and in the sliding process, the mounting part of the sliding shaft slides along the sliding groove of the rotating shaft 103 so as to adjust the posture of the movable air guide strip at any time and promote the sliding in the guide sliding groove to be smoother.
In order to avoid rapid turning of the air flow, after the movable air guide strip 2 slides out, the outer surface of the movable air guide strip and the outer surface of the fixed air guide strip 1 can be in streamline transition. In this case, the person skilled in the art should have good access to the guide direction of the guide chute and the transition between the lower end of the fixed air guide strip and the movable air guide strip.
In addition, this air conditioner's aviation baffle structure still includes: the large air deflector 3 is arranged at the air outlet of the air conditioner indoor unit, and the large air deflector 3 can close or open the air outlet under the driving of the second driving mechanism. The large air deflector 3 can promote the smooth or closed air channel by opening and closing the air outlet, and basically corresponds to the starting state and the shutdown state of the air conditioner indoor unit. In addition, in some embodiments, the air is further guided by the large air guide plate 3 to further extend the air guide profile. When the movable air guide strip 2 and the fixed air guide strip 1 are on the same extension line, the air guide lines of the movable air guide strip 2 and the fixed air guide strip are the longest, the tail end of the movable air guide strip 2 is still positioned at the inner side of the large air guide plate 3 (namely, at one side of the inner part of the air conditioner), and therefore in order to guide the wind to a longer distance, the air guide stroke can be prolonged by means of the large air guide plate 3.
Besides the above air guide structure, the air guide plate of the air conditioner indoor unit further comprises: and the left and right air guide blades 6 are arranged on an air outlet channel between the cross-flow wind wheel 4 and the fixed air guide strip 1. The left and right air guide blades 6 can guide the air flow to the left and right.
Based on the various embodiments, in order to further improve the wind guiding effect, the lower surfaces of the fixed wind guiding strip 1 and the movable wind guiding strip are convex cambered surfaces. This utilizes the coanda effect, and its principle is: the fluid tends to flow along the surface of the protruding object instead of moving away from the original flow direction. When there is fluid viscosity between the fluid and the surface of the object over which it flows, the fluid follows the surface of the object as long as the curvature is not large. The wind can flow forward along the surface of the bulge, and large-angle and long-distance air supply is realized.
The invention also provides a refrigerating air conditioner internal unit, and the air deflector structure is applied to the refrigerating air conditioner internal unit. The method specifically comprises the following steps: an air inlet 7 and an air outlet are arranged on a shell 8; an air duct from the air inlet 7 to the air outlet is formed in the shell 8, and the air guide plate structure is arranged on the air duct.

The evaporator 5 can cool or heat air entering the air conditioner indoor unit, the cross flow wind wheel 4 can accelerate the flow velocity of the air, and the left and right wind guide blades 6 realize the left and right guide of the air.
Because the change of different wind-guiding strips, wind-guiding blade need be carried out to wind-guiding plate structure under the condition of difference, consequently need have certain control structure, so, air conditioner internal unit still includes: and the control structure is connected with the first driving mechanism of the air deflector structure. In addition, the control structure can also be connected with a second driving mechanism and drives a master control structure of an air conditioner internal unit.
The invention also provides an air guide control method of the air conditioner indoor unit, which comprises the following steps:
