The embodiment of the invention provides a control method of 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.

Fig. 1 is a schematic structural view of a wall-mounted type air conditioning indoor unit according to an embodiment of the present invention; fig. 2 is a schematic cross-sectional enlarged view of the wall-mounted air conditioning indoor unit shown in fig. 1; fig. 3 is an enlarged view of fig. 2 at a.

As shown in fig. 1 to 3, a wall-mounted type air conditioning indoor unit according to an embodiment of the present invention may generally include a cabinet 10 and a wind guide plate 60.

The cabinet 10 is a long bar extending in a horizontal direction for hanging on an indoor wall. The lateral direction of the housing 10, i.e. its length direction, is indicated by x in the figure. The casing 10 of the present embodiment includes a framework for forming a basic frame of the indoor unit and body components such as a volute and a volute tongue for defining the air duct 15, and is not a pure air conditioning casing. The casing 10 is opened with a first air supply port 11 facing forward and a second air supply port 12 facing downward, and blows an air flow in the casing 10 into a room to condition indoor air. The air 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, or fresh air introduced in a fresh air mode, and the like. The casing 10 is further formed with an air duct 15 having an outlet connected to the first and second blowing

ports

11 and 12. The air guide plate 60 is rotatably provided at the second blowing port 12 for guiding the blowing direction thereof. Specifically, the front-rear air blowing direction of the second air blowing port 12 is guided.

The shape configuration of the air duct 15 can guide the heat exchange air flow in the air duct to gradually flow out of the first air supply opening 11 towards the air flow center in a converging manner to form a converging effect, so that the wind power is very strong, the air supply distance is farther, the requirements of the wall-mounted air conditioner indoor unit on long-distance air supply and strong air supply are met, the air supply range is larger, the refrigerating/heating speed of each part of the indoor space is more uniform, and the human body feels more comfortable. Since the first blowing port 11 is provided at the front of the casing 10, the converged air is blown forward, and the blowing distance is greater.

In some embodiments, as shown in fig. 2, the casing 10 includes a division bar 152 and a volute tongue 151 and a volute 153 arranged in front and rear. The separation strip 152 is located below the front end of the volute tongue 151 and in front of the lower end of the volute casing 153 to define the air duct 15 together with the volute tongue 151 and the volute casing 153. The air duct 15 is a through-flow air duct. The division bar 152 and the front end of the volute tongue 151 define a first supply port 11, and the division bar 152 and the lower end of the volute 153 define a second supply port 12.

The distance between the volute tongue 151 (specifically, the ba section thereof) and the separation bar 152(ed section) is gradually reduced along the airflow direction near the first air supply outlet 11, and a tapered section of the air duct 15 is formed. In other words, the flow cross section of the air duct 15 becomes gradually smaller in the air flow direction adjacent to the first supply outlet 11. The wall-mounted air conditioning indoor unit further includes a guide 30. The flow guide member 30 is a rod-shaped member parallel to the length direction (x direction) of the first air supply opening 11, is disposed in the air duct 15, and defines

air outlet gaps

154 and 155 with (the sa section of) the volute tongue 151 and (the ed section of) the flow guide member, respectively, and is configured to guide the air flow blown toward the first air supply opening 11 to the volute tongue 151 and the separation strip 152 of the air duct 15, so that the air flow gradually converges toward the center of the air flow and flows out of the first air supply opening 11 under the guidance of the tapered section of the air duct 15. The volute 153 is a volute of a cross-flow fan, and is specifically a curved structure with a concave side facing forward; the section (sck) of the volute tongue 151 other than the as segment is the volute tongue of the crossflow blower. It includes a kc section extending rearwardly and downwardly and a cs section extending forwardly and downwardly. And the inclination angle of the cs section is theta, preferably the theta is more than or equal to 25 degrees, so that the air flow is favorably guided to the obliquely lower part, and the heating and air outlet are favorably realized.

Due to the addition of the air guide 30, the flow cross section of the

outlet air gaps

154, 155 is necessarily smaller than that of the original air duct 15, which makes the air flow velocity faster. The high-speed air flow is gradually converged towards the center direction of the air flow in the outward flowing process under the guide of the gradually-reduced section of the air duct 15 to form a convergence effect, so that the wind power is very strong, the air supply distance is farther, the requirements of a wall-mounted air conditioner indoor unit on remote air supply and strong air supply are met, the air supply range is larger, the refrigerating/heating speed of each part of the indoor space is more uniform, and the human body feels more comfortable.

In some embodiments, as shown in fig. 2 and 4, the two side surfaces (the inner side surface 32 and the outer side surface 31) of the flow guiding element 30 facing the first air supply opening 11 and facing away from the first air supply opening 11 are convex curved surfaces, the two top ends a1 and a2 are formed at the joint of the two side surfaces, and the two top ends a1 and a2 can be provided with round corners, so that the cross section (the section perpendicular to the x axis) of the flow guiding element 30 is shaped like an olive. The convex curved surface of the flow guide member 30 protruding forward can guide the airflow near the surface to flow along the surface, so as to gradually converge toward the center direction, and to perform the convergence action on the airflow together with the tapered section of the air duct 15, thereby improving the convergence effect of the airflow.

Specifically, as shown in fig. 2 to 4, the inner side surface 32 of the flow guide member 30 facing the first air blowing port 11 may be formed by joining two circular arc surfaces CA1 and CA2, and the radius thereof is R2, so that the inner side surface 32, particularly the middle point C thereof, protrudes further outward, and the air flow blowing thereto can be divided more uniformly to both sides of the point C. The outer side surface 31 back to the first air supply outlet 11 is a section of arc surface, and the metal plate is R1, so that the requirement of attractive appearance is met, and the manufacturing is convenient. The radiuses R1, R2 and the lengths of the circular arc surfaces CA1 and CA2 at the two ends of the inner side surface 32 can be further made equal, so that the air flows to the two parts tend to be equal. The distance between the two top ends of the flow guide piece 30 is H, and the following requirements are met: R1/H is more than or equal to 0.5 and less than or equal to 0.8, R2/H is more than or equal to 0.5 and less than or equal to 0.8, and further R1/H is more than or equal to 0.3 and less than or equal to 0.6, and R2/H is more than or equal to 0.3 and less than or equal to 0.6. In this way, the width (the maximum dimension in the vertical direction) of the air guide member 30 and the curvature of the front and rear surfaces are more coordinated, so as to balance the air guiding effect and the flow resistance.

In some embodiments, as shown in fig. 3, the width of the first blowing port 11 may be h, and the relationship between the width and the width satisfies: H-H is more than or equal to 4mm and less than or equal to 10mm, and H-H is more than or equal to 6mm and less than or equal to 8mm, so that the downward inclined part of the air outlet gap 154 formed by the flow guide piece 30 and the volute tongue 151 of the air duct and the upward inclined part of the air outlet gap 155 formed by the separation strip 152 are not too long, and the increase of the airflow resistance is avoided.

As shown in fig. 3, the closest distance between the outer surface of the flow guide member 30 and the volute tongue 151 is d1, the closest distance between the outer surface of the flow guide member 30 and the partition strip 152 is d3, preferably, d3 is greater than or equal to 1.5d1 and less than or equal to 2d1, and further d3 is greater than or equal to 1.7d1 and less than or equal to 1.9d1, so that the gap between the flow guide member 30 and the partition strip 152 is larger, the air volume is larger, the gap between the flow guide member and the volute tongue 151 is smaller, and the air volume is smaller, so that the air guiding force of the partition strip 152 is greater than the air guiding force of the volute tongue 151 when the two air flows are converged and gathered, and the air flow direction is indicated by an arrow in fig. 2 for reference. In the refrigeration mode, the rising and flowing cold air can fully avoid the human body and scatter downwards after reaching the highest point, so that the shower type refrigeration experience is realized. Moreover, the air flow is blown upwards to be beneficial to improving the air supply distance.

Referring to fig. 3, the width of the first blowing port 11 is h. The inventor finds that the relation between d1 and h has a large influence on the air supply distance through a plurality of tests. When d1 is more than or equal to 0.25h and more than or equal to 0.15h, d1 is more than or equal to 0.22h and the air supply distance is larger.

As shown in fig. 2, the distance d2 between the bottom end of the air guiding element 30 and the upper surface of the air guiding plate 60 is used for the air flow to flow through the air outlet gap 155. Preferably, d2 is not less than 1.5d1 and not more than 2d1, so that more air flows enter the air outlet gap 155, the force for upward air guiding of the separating strips 152 is greater than the force for downward air guiding of the volute tongues 151, and the two air flows are converged and gathered to flow upward integrally.

As shown in fig. 2 and 3, the section (as section) of the volute tongue 151 defining the outlet gap 154 is a curved section with a concave side facing downward, and may be an arc or be formed by connecting multiple arcs, and has a front end point a, a highest point b and a rear end point s, which surround the flow guide 30 above the flow guide 30. The upper surface of the separation strip 152 is formed in a concave curved shape extending obliquely upward from the rear to the front, and is located at the front lower portion of the baffle 30. Thus, the air outlet gap 154 and the air outlet gap 155 are both curved or further arc-shaped, so that the airflow direction is changed to be smoother, and the airflow resistance is reduced.

As shown in fig. 2, the wall-mounted air conditioner indoor unit may be an indoor unit of an air conditioner that performs cooling/heating through a vapor compression refrigeration cycle, and further includes a heat exchanger 40 and a blower 50. The heat exchanger 40 is disposed in the casing 10, and is configured to exchange heat with an air flow flowing through the casing to form a heat exchange air flow, i.e., a cold air or a hot air, which may be a three-stage fin heat exchanger. The fan 50 is disposed in the casing 10, and is configured to cause indoor air to enter the casing 10 through the air inlet 13 at the top of the casing 10, to cause the indoor air to exchange heat with the heat exchanger 40 to form heat exchange air flow, to cause the heat exchange air flow to flow through the air duct 15 to the first air supply outlet 11 and the second air supply outlet 12, and to finally blow the air into the room through the first air supply outlet 11 and the second air supply outlet 12.

In some embodiments, the deflector 30 may be configured to move back and forth in order to adjust the size of the

air outlet gaps

154, 155. Specifically, the

air outlet gaps

154 and 155 can be enlarged by moving the diversion member 30 backward to improve the wind power, accelerate the cooling/heating speed and prolong the air supply distance; the

air outlet gaps

154 and 155 can be adjusted to be small by moving the diversion member 30 forward to reduce the wind force, simulate the natural wind and ensure higher air flow comfort. Furthermore, the front and back movement of the diversion member 30 also facilitates the closing of the first air supply outlet 11

Fig. 5 is a schematic view of a drive mechanism for the deflector.

In some embodiments, as shown in fig. 5, the driving mechanism for driving the deflector 30 to translate back and forth is a rack and pinion mechanism, which is installed at the lateral side of the casing 10 so as not to affect the airflow. The driving mechanism includes a rack 71 extending in the front-rear direction and fixed to the air guide 30, a gear 72 engaged with the rack 71, and a motor 73 for driving the gear 72 to rotate to drive the rack 71 to translate back and forth. The motor 73 may be fixed to the cabinet 10, and the rack 71 may be slidably installed to the cabinet 10 in the front and rear directions. The motor 73 is controllably reversible to allow the baffle 30 to translate back and forth in a reciprocating manner. The motor 73 may be a stepper motor.

Fig. 6 is a schematic view of the wall-mounted air conditioning indoor unit guiding air at a large opening angle of the air deflector, and fig. 7 is a schematic view of the wall-mounted air conditioning indoor unit guiding air at a small opening angle of the air deflector.

As shown in fig. 6 and 7, TE represents a wall, and a lower area DE of the wall-mounted air conditioning indoor unit is a range within which the air can be blown by the second air blowing port 12, that is, point D is a farthest air blowing position of the second air blowing port 12. Point F represents the farthest blowing position of the first blowing port 11.

Fig. 8 is a schematic view illustrating a method of controlling a wall-mounted air conditioner indoor unit according to an embodiment of the present invention.

The control method of the embodiment of the invention is used for controlling the wall-mounted air conditioner indoor unit of any embodiment, and generally comprises the following steps:

step S802: and detecting the indoor environment temperature.

Step S804: and judging whether the indoor environment temperature is in a preset comfortable temperature interval or not. For example, the comfort temperature range is 23 ℃ to 26 ℃. If yes, go to step S806. If not, go to step S808.

Step S806: that is, when it is determined that the indoor ambient temperature is in the comfortable temperature range, the air guide plate 60 is controlled to close the second air supply port 12, so that the first air supply port 11 supplies air forward in a converging manner.

Step S808: that is, when it is judged that the indoor ambient temperature is not in the comfortable temperature range, it is judged whether or not there is an air supply accessible range in which the human body enters the second air supply outlet 12. Specifically, an infrared distance sensor may be installed at the bottom of the front side of the casing 10, so as to determine whether or not the human body enters the air blowing accessible range of the second air blowing port 12 by detecting the distance between the human body and the infrared distance sensor in the horizontal direction.

Step S510: if it is determined that the human body enters the range in the above step, the air guide plate 60 is controlled to guide the air toward the area (DE) where the human body is located. Specifically, step S510 may include:

the range of the second blowing port 12 that is accessible to the blowing air is divided into a plurality of sub-areas arranged in tandem, as shown in fig. 7, five sub-areas such as DD1, D1D2, D2D3, D3D4, and D4E.

When the human body is detected to enter a sub-area, the air guide plate 60 is controlled to guide the air to the sub-area at a fixed opening angle.

When it is detected that the human body leaves the sub-area and enters another sub-area, the air guide plate 60 is controlled to be adjusted to another fixed opening angle to guide air towards the other sub-area. That is, the air guiding plate 60 can guide air only towards the fixed angles, and the air guiding plate 60 is kept still as long as the human body does not leave a certain sub-area, so as to avoid frequent rotation.

Of course, in some alternative embodiments, the wind deflector can also rotate strictly along with the change of the position of the human body, so that the wind is always guided to the direction of the human body.

In some embodiments, if it is determined that the indoor ambient temperature is not in the comfortable temperature range and the human body does not enter the air supply accessible range of the second air supply opening 12, the air guide plate 60 is controlled to guide air forward and downward and the opening angle is controlled to be 0-25 °, so that the air guide direction is as far forward as possible to meet the user requirement.

The wall-mounted air conditioner indoor unit of the embodiment of the invention can utilize the first air supply outlet 11 to supply air forwards in a converging manner, and the air supply distance is longer; the downward second air supply outlet 12 can supply air to the lower part and the front lower area of the air conditioner, and the air supply range of the air conditioner is wider due to the cooperation of the two parts. In addition, the control method of the embodiment of the invention sets a comfortable temperature interval, when the indoor temperature is in the comfortable temperature interval, the second air supply outlet 12 is closed, only the first air supply outlet 11 is used for carrying out aggregated air supply, and the air is blown to the far away of the room and away from the human body, so that the wind sensation of the human body is reduced. When the indoor temperature does not reach the comfortable temperature interval, the indoor environment does not reach the comfortable degree on the whole. At this time, if the air supply accessible range of the human body entering the second air supply outlet 12 is located or substantially reaches under the indoor unit of the wall-mounted air conditioner, it is determined that the human body is actively selecting to blow air, at this time, the air deflector 60 is controlled to guide air towards the human body area, so as to achieve the effect that the air moves along with the human body, and the human body is preferably blown, so that the human body is in a comfortable state as soon as possible.
