technical field

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

Background technique

Because the density of cold air is relatively high, it tends to sink, and the density of hot air is relatively low, and it tends to rise. Therefore, the air conditioner needs to blow the cooler air upwards as much as possible when cooling, and blow the hot air toward the ground as much as possible when heating, so that the cold air or hot air can spread more evenly in the indoor space and make the cooling and heating speed faster.

The existing wall-mounted air conditioner indoor unit is usually provided with a forward-facing air outlet, and air guide structures such as air guide plates and swing blades are used to guide the air outlet direction of the air supply air, so as to realize upward blowing or downward blowing. However, the various current air guiding structures have limited air guiding angles, and can only supply air obliquely upward or downward. It is difficult for cold air or hot air to reach the roof or the ground, which affects the cooling or heating effect.

SUMMARY OF THE INVENTION

The purpose of the present invention is to provide a wall-mounted air conditioner indoor unit that overcomes or at least partially solves the above problems, so as to enhance the upward blowing and/or downward blowing effect of the wall-mounted air conditioner indoor unit.

A further object of the present invention is to make the air outlet volume of the upper channel and the lower channel adjustable.

In particular, the present invention provides a wall-mounted air conditioner indoor unit, which includes:

a casing with an air outlet opening thereon; and

An air guide cover plate is arranged on the outside of the air outlet to define an air guide channel with the outer peripheral surface of the casing, and is used to guide the air supply air flowing out of the air outlet upward along the outer peripheral surface of the casing and/or downward flow; and

At least a partial section of the wind deflector plate constitutes a wind deflector, and the wind deflector is configured to adjust the opening angle of the wind guide channel rotatably about a horizontal axis.

Optionally, the air guide cover plate can be installed on the casing so as to be able to translate up and down, and has a partition portion protruding from its inner surface toward the outer peripheral surface of the casing, so as to divide the air guide channel into openings. an upper channel facing upward and a lower channel opening downward, and configured to: move to a position where the partition is positioned above the air outlet to direct the supply air flow downward by the lower channel; or The partition is moved to a position below the air outlet to guide the supply air flow upward by the upper channel.

Optionally, the partition is formed on the inner surface of the air deflector; the air deflector also includes two installation plates arranged at intervals, and the two installation plates can be installed on the machine so as to be able to move up and down. the casing, the deflector is located between the two mounting plates and is rotatably mounted on the two mounting plates.

Optionally, the air outlet is opened on the front surface of the casing, the deflector is located directly in front of the air outlet, and is rotatably installed on the two mounting plates around the horizontal horizontal axis; The mounting plate is gradually bent and extended backward from the front side of the lateral end of the casing to the end cover on the lateral side of the casing, and is mounted on the end cover so as to be able to translate up and down.

Optionally, each of the mounting plates has a wind shield extending toward the end cover for blocking the rearward flow of the supply air flow.

Optionally, the partition part has a tip adjacent to the outer peripheral surface of the casing; the upper surface of the partition part starts from the tip, extends away from the casing and gradually slopes upward, and an inner concave arc surface tangent to the inner surface of the remaining part of the baffle; and the lower surface of the partition starts from the tip, extends away from the casing and slopes downward gradually, and An inner concave arc tangent to the inner surface of the remaining part of the deflector.

Optionally, the axis of rotation of the baffle is located at the tip.

Optionally, the air guide cover plate is further configured to be movable to a position where the partition portion is located in the middle of the air outlet, so as to guide part of the air supply air flow through each of the lower channel and the upper channel.

Optionally, the entire front surface of the casing is a vertical plane; and the air outlet is opened at a lower portion of the front surface of the casing.

Optionally, the ratio of the distance between the lower edge of the air outlet and the bottom end of the front surface of the casing and the width of the air outlet is greater than 1/2.

In the wall-mounted air conditioner indoor unit of the present invention, an air guide cover plate is arranged outside the casing, and the wind guide cover plate and the outer peripheral surface of the casing define an air guide channel. After the air supply air (such as cold air, hot air, fresh air or purification air flow, etc.) inside the casing is blown out from the air outlet of the casing, it is blocked by the air guide plate and cannot be blown out directly horizontally, but along the outer circumference of the casing. Blow face up and/or down. Since the air supply air flows close to the outer peripheral surface of the casing, forming a Coanda effect, it can smoothly reach the roof or the ground along the outer peripheral surface of the casing, so that the cooling or heating effect of the wall-mounted air conditioner indoor unit is better. At the same time, it can also avoid cold air or hot air blowing people, resulting in poor human comfort.

In addition, since at least a partial section of the wind deflector plate is a wind deflector, the wind deflector can rotate around the horizontal axis to adjust the opening angle of the wind guide channel. When the air deflector rotates so that the upper end is away from the casing and the lower end is close to the casing, the opening angle of the upper side of the air guide channel becomes larger, and the opening angle of the lower side becomes smaller. When the air deflector rotates so that the upper end is close to the casing and the lower end is far away from the casing, the opening angle of the upper side of the air guide channel becomes smaller, and the opening angle of the lower side becomes larger. In this way, the air flow, air speed and air angle range of the air guide channel can be adjusted.

Further, in the wall-mounted air conditioner indoor unit of the present invention, the air guide cover plate can be installed on the casing so as to be able to translate up and down, and the partition part divides the air guide channel into an upper channel with an upward opening and a lower channel with an opening downward, so that the The wall-mounted air conditioner indoor unit has up-blowing mode and down-blowing mode to choose from, in order to enhance the cooling and heating effect. For example, when the air-conditioning heating needs to operate in the downward blowing mode, the air deflector plate is moved to the position above the air outlet, and the air supply air is guided downward by the lower channel. When the air-conditioning refrigeration needs to operate in the upward blowing mode, the air guide cover plate is moved to the position below the air outlet, and the air supply airflow is guided upward by the upper channel, the structure is simple and the adjustment is convenient.

Further, in the wall-mounted air conditioner indoor unit of the present invention, the upper and lower surfaces of the partition are both concave arc surfaces, so that the direction change of the supply air flow is more gentle when it is blown out from the air outlet and then turned upward or downward. Reduce wind loss and noise.

Further, in the wall-mounted air conditioner indoor unit of the present invention, the front surface of the casing is a vertical plane, so that the air supply air can form a Coanda effect on the front surface of the casing, so as to better move upward or downward along the front surface of the casing. flow down. 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 cabinet to the width of the air outlet should be greater than 1/2, so that the front surface of the cabinet below the air outlet has a sufficient height so that when the air conditioner is running in the blowing mode, In order to make the lower channel longer, it is more conducive to the formation of the Coanda effect, and the supply air flow is better guided directly below.

As shown in FIGS. 1 to 10 , the wall-mounted air conditioner indoor unit according to the embodiment of the present invention may generally include a cabinet 10 and an air guide cover plate 20 .

The casing 10 is provided with an air outlet 12 for discharging the air supply air in the casing 10 to the room. The supply air flow can be cold air produced by the wall-mounted air conditioner indoor unit in the cooling mode, hot air produced in the heating mode, or fresh air introduced in the fresh air mode, or purified air generated in the purification mode, etc. . The casing 10 can be a horizontally extending elongated structure as a whole.

The air guide cover plate 20 is disposed outside the air outlet 12 to define an air guide channel 21 with the outer peripheral surface of the casing 10 . That is, the air guide cover plate 20 is parallel or nearly parallel to the outer peripheral surface of the casing 10 , and the space between them constitutes the air guide channel 21 . The air guide channel 21 is used to guide the air supply air flowing out of the air outlet 12 to flow upward and/or downward along the outer peripheral surface of the cabinet 10 . That is, after being blown out from the air outlet 12 of the casing 10, the supply air flow (such as cold air, hot air, fresh air, or purified air) is blocked by the inner wall of the air guide cover plate 20 and cannot be directly blown out horizontally, but along the casing. The periphery of 10 is blown up and/or down. The upward and/or downward blowing here means that the supply air flow can be blown out only upwards, or only downwards, or both upwards and downwards. FIGS. 1 to 6 illustrate the situation in which the air supply air is blown upward, and FIGS. 7 to 10 illustrate the situation in which the air supply air is blown out downward.

Since the air supply air flows upward or downward against the outer peripheral surface of the casing 10, a Coanda effect (also referred to as an attachment effect) can be formed, so that the outer peripheral surface of the casing 10 can smoothly reach the roof or the ground, forming a The shower-type air supply effect and the carpet-type air supply effect make the cooling or heating effect of the wall-mounted air conditioner indoor unit better. At the same time, it can also avoid the discomfort caused by cold or hot wind.

In some embodiments, the area on the outer peripheral surface of the casing 10 through which the supply air flows can be a flat surface, so that the supply air flow can better fit the outer peripheral surface of the casing 10 . For example, as shown in FIG. 1 , for the solution in which the air outlet 12 is opened on the front side of the casing 10 , the front surface of the casing 10 is the outer peripheral surface through which the fresh air flows, so the front surface of the casing 10 can be a flat surface.

In some embodiments, at least a partial section of the wind deflector panel 20 may constitute a deflector plate 201 , and the deflector plate 201 is configured to be rotatable about a horizontal axis to adjust the opening angle of the wind deflector channel. At least a partial section of the wind deflector panel 20 refers to a partial section or the entire section of the wind deflector panel 20 . The "horizontal axis" here does not extend along the strictly horizontal direction in the physical sense, and clamping a small acute angle with the strictly horizontal direction does not affect the realization of the above-mentioned features and functions.

When the air deflector 20 is used to guide the supply air to blow upward, the deflector 201 can be rotated to keep the upper end away from the casing 10 and the lower end close to the casing 10 (that is, from the state shown in FIG. 6 to the one shown in FIG. 4 ) state), so that the opening angle of the upper side of the air guide channel 21 becomes larger, so that the air flow can flow out more smoothly, the air volume and wind speed are increased, and the range of the air outlet angle is increased; 201 (rotating from the state shown in FIG. 4 to the state shown in FIG. 6 ), the opposite effect to the above-mentioned effect can be obtained.

When the air deflector 20 is used to guide the supply air to blow down, the deflector 201 can be rotated so that its lower end is far away from the casing 10 and its upper end is close to the casing 10 (ie, it is rotated from the state shown in FIG. 10 to the state shown in FIG. 9 ). ), so that the opening angle of the lower side of the air guide channel 21 becomes larger, so that the air flow can flow out more smoothly, the air volume and wind speed are increased, and the range of the air outlet angle is increased; (rotating from the state shown in FIG. 9 to the state shown in FIG. 10 ), the opposite effect can be obtained.

In some embodiments, as shown in FIG. 1 to FIG. 10 , the wind deflector 20 can be mounted on the casing 10 so as to be able to translate up and down. The wind deflector 20 has a partition portion 23 protruding from the inner surface thereof toward the outer peripheral surface of the cabinet 10 . The partition part 23 is used to partition the air guide channel 21 into an upper channel 212 with an upward opening and a lower channel 214 with an opening downward. The air deflector 20 is configured to: move to position the partition 23 above the air outlet 12 so as to guide the supply air flow downward by the lower channel 214, as shown in FIGS. 7 to 10; or to move the partition 23 to the outlet The lower position of the tuyere 12 is to guide the supply air flow upward by the upper channel 212, as shown in FIG. 1 to FIG. 6 . The partition portion 23 and the rest of the air guide cover plate 20 may be integral parts made by an integral molding process.

In this way, the indoor unit of the wall-mounted air conditioner has an upward blowing mode and a downward blowing mode for selection, so that the cooling and heating effects are significantly improved. For example, when the air conditioner needs to operate in the downward blowing mode, the air deflector 20 is moved to the position where the partition 23 is located above the air outlet 12, and the air flow is guided downward by the lower channel 214, as shown in FIG. 9 . When the air-conditioning cooling needs to operate in the upward blowing mode, the air deflector 20 is moved to a position where the partition 23 is located below the air outlet 12, and the upper channel 212 guides the supply air upward, as shown in FIG. 4 . Of course, the air deflector 20 can also be configured to be movable to a position where the partition 23 is located in the middle of the air outlet 12 (not shown, that is, in the position between FIG. 4 and FIG. 9 ), so that the lower channel 214 The upper channel 212 and the upper channel 212 respectively guide part of the air supply air flow, so that the wall-mounted air conditioner indoor unit supplies air in both directions at the same time, thereby increasing the air conditioning speed.

In some embodiments, as shown in FIGS. 4 and 5 , the partition 23 may be formed on the inner side surface of the baffle 201 . In addition, the wind deflector 20 further includes two mounting plates 202 arranged at intervals. The two mounting plates 202 are mounted on the casing 10 so as to be able to translate up and down. The air guide plate 201 is located between the two mounting plates 202 and is rotatably mounted on the two mounting plates 202 . That is, the wind deflector plate 20 includes three sections arranged in sequence, namely the left mounting plate 202 , the air guide plate 201 and the right mounting plate 202 . The deflector 201 is installed on the mounting plate 202 to guide the supply air flow, and the two mounting plates 202 are used for moving connection with the casing 10, so that there is no need to install a moving drive mechanism on the deflector 201 to avoid affecting the Wind guide. One of the mounting plates 202 may be provided with a motor (not shown) for driving the baffle plate 201 to rotate.

Specifically, as shown in FIGS. 1 to 10 , the air outlet 12 can be opened on the front surface of the casing 10 . The deflector plate 201 is located directly in front of the air outlet 12 and is rotatably mounted on the two mounting plates 202 around the transverse horizontal axis.

Each mounting plate 202 is gradually bent and extended backward from the front side of the lateral end of the casing 10 to the end cover 106 on the lateral side of the casing 10 , and can be mounted on the end cover 106 in an up-down translational manner. In this way, there is no need to provide a drive mechanism on the front side of the cabinet 10, resulting in occupying an air outlet space. Each mounting plate 202 has a wind blocking portion 2021 extending toward the end cover 106 for blocking the backward flow of the supply air flow, so that the supply air flow can flow upward or downward better, and avoid the backward flow diffusion affecting the upward and downward flow wind.

In some embodiments, as shown in FIGS. 4 and 5 , the partition 23 has a tip 230 adjacent to the outer peripheral surface of the casing 10 . The tip 230 is close to the outer peripheral surface of the casing 10 , so that it can fit with the outer peripheral surface of the casing 10 . When the air deflector 20 is in the blowing position, the sealing performance between the partition 23 and the outer peripheral surface of the casing 10 is better, so as to prevent the airflow from leaking downward; when the air deflector 20 is in the downward blowing position, the partition The sealing performance between 23 and the outer peripheral surface of the casing 10 is better, and the upward leakage of the air flow is avoided. Of course, if the tip 230 is too close to the outer surface of the casing 10 , when the wind deflector 20 moves up and down, the tip 230 and the outer surface of the casing 10 may rub against each other, which may generate relatively large noise. To avoid the noise, a certain gap can also be reserved between the tip 230 and the outer surface of the casing 10 .

4 and 5 , the upper surface 231 of the partition portion 23 starts from the tip 230, extends away from the casing 10 (in the specific embodiment shown in the figures, refers to the front) and gradually slopes upward, And the inner concave arc surface tangent to the inner surface of the rest of the deflector 201 . Likewise, the lower surface 232 of the partition portion 23 is a concave arc surface that starts from the tip 230 , extends away from the casing 10 and slopes downward gradually, and is tangent to the rest of the inner surface of the baffle 201 . In this way, when the supply air flow is blown out from the air outlet 12 and then turned upward or downward, it will be gradually turned along the upper or lower surface of the partition 23, the process is more moderate, and the wind loss and noise are smaller.

When the air deflector 20 is in the upward blowing mode, the tip 230 of the partition 23 can be positioned opposite to the lower edge of the air outlet 12, so that the upper surface 231 of the partition 23 is in contact with the lower wall of the air duct 40, refer to Figure 4. In addition, since the upper surface 231 of the partition portion 23 is a concave arc surface, the upper surface 231 is equivalent to the extension of the lower wall of the air duct 40 , so that the air flow from the air duct 40 enters smoothly and with low resistance. The guide range of the partition 23 .

Similarly, when the air deflector 20 is in the downward blowing mode, the tip 230 of the partition 23 can be positioned opposite to the upper edge of the air outlet 12 so that the lower surface 232 of the partition 23 is in contact with the upper wall of the air duct 40 Next, refer to Figure 9. Since the lower surface 232 of the partition part 23 is a concave arc surface, the lower surface 232 is equivalent to the extension of the upper wall of the air duct 40 , so that the supply air flow from the air duct 40 enters the partition part smoothly and with low resistance 23 boot range.

The axis of rotation of the deflector 201 is located at the tip 230 of the partition 23 . In this way, when the deflector 201 rotates, the position of the tip 230 of the deflector is basically unchanged, and is always close to the upper edge or the lower edge of the air outlet 12 with a minimum distance to avoid air leakage therebetween.

In some embodiments, as shown in FIGS. 1 to 10 , the entire front surface of the casing 10 can be a vertical plane (the front surface of the casing 10 is a part of the outer peripheral surface of the casing 10 ), specifically, it can be A vertical plane or a curved surface such as an arc surface whose axis extends vertically. The air outlet 12 may be opened at the lower portion of the front surface of the casing 10 . More specifically, the air outlet 12 may be a long strip with a longitudinal direction parallel to the lateral direction of the cabinet 10 .

Please refer to FIG. 5 , the ratio of the distance (de) between the lower edge d of the air outlet 12 and the bottom end e of the front surface of the casing 10 and the width (cd) of the air outlet 12 is greater than 1/2, that is, de/cd>1/ 2, preferably greater than 3/4. In this way, when the indoor unit of the wall-mounted air conditioner operates in the downward 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 supply air to flow downward and enhance the Coanda effect. In addition, the distance between the partition portion 23 and the bottom end of the air deflector plate 20 can also be made larger than the distance between the partition portion 23 and the top end of the air deflector plate 20 (specifically, the tip 230 of the partition portion 23 can be used as the measurement reference), that is, the partition portion 23 It is located on the upper part of the air deflector plate 20 so as to better guide the airflow to blow down in the downward blowing mode, making up for the short guiding distance (ie de) of the front surface of the casing on the lower side of the air outlet 12.

As shown in FIGS. 11 to 14 , at least one end cover 106 of the casing 10 is provided with a rack and pinion mechanism for driving the wind deflector 20 to translate up and down to switch between the upper blowing position and the lower blowing position. Preferably, both end covers 106 are provided with a rack and pinion mechanism to drive the lateral ends of the wind deflector 20 to move up or down synchronously, so that the movement is more stable and smooth.

Each rack and pinion mechanism includes a motor 71 , a gear 72 and a rack 73 that mesh with each other. The motor 71 is disposed inside the end cover 106 . The gear 72 is mounted on the motor 71 , and the rack 73 is disposed on the inner side of the end cover 106 so as to be able to move up and down, and a part of the gear rack 73 protrudes to the outer side of the end cover 106 through the vertical strip hole 1061 opened on the end cover 106 , so that Attached to the mounting plate 202 . 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 wind deflector 20 to translate up and down.

Specifically, as shown in FIG. 13 to FIG. 14 , a mounting member 107 can be fixed to the inner wall of the end cover 106 . The mounting member 107 is connected with a plurality of mounting portions 1062 provided on the inner wall of the end cover 106 by screws through a plurality of mounting portions 1072 provided thereon. The mount 107 is formed with two spaced apart and vertically extending slide rails 1071 . Two sliding grooves 731 with opposite opening directions are formed at both ends of the rack 73 in the width direction. That is, the function of the mounting member 107 is to form the slide rail 1071 for the rack 73 to be mounted thereon so as to be able to translate up and down.

A bracket 108 is also fixed on the inner wall of the end cover 106 for installing the motor 71 . The rack 73 is sandwiched between the gear 72 and the mounting member 107 , or the gear 72 is located on the side of the mounting member 107 facing away from the inner wall of the end cover 106 . The side of the rack 73 facing the gear 72 is formed with teeth to engage with the gear 72, and the side facing the end cover 106 protrudes outward to form a protruding bar 732, the protruding bar 732 extends through the vertical strip hole 1061. The cover 106 is attached to the mounting plate 202, for example by means of screws. Specifically, the protruding strips 732 can be connected to the wind shielding portion 2021 . In this way, the wind blocking portion 2021 is used not only for connecting the protruding strips 732 but also for blocking the airflow, and the design is very ingenious.

In this embodiment, the mounting member 107 and the bracket 108 are arranged on the inner wall of the end cover 106 to install the main structure of the rack and pinion mechanism on the inner side of the end cover 106 without affecting the appearance of the wall-mounted air conditioner indoor unit. And by opening a vertical long strip hole 1061 on the end cover 106 to connect the mounting plate 202 located outside the end cover 106, the design is very simple and reasonable.

As shown in FIG. 4 , an air inlet 11 is opened on the top of the casing 10 , an air duct 40 is arranged inside the casing 10 , and the outlet of the air duct 40 is connected to the air outlet 12 . The cross-flow fan 50 whose axis extends in the lateral direction is disposed at the inlet of the air duct 40 . The three-stage heat exchanger 30 is surrounded above the cross-flow fan 50 . When the indoor unit of the wall-mounted air conditioner operates in the cooling mode or the heating mode, the indoor air enters the interior of the casing 10 through the air inlet 11, completes heat exchange with the three-stage heat exchanger 30, and is finally sucked into the air duct 40 by the cross-flow fan 50. , flows to the air outlet 12 .

Fig. 11 shows a more specific structure of the wall-mounted air conditioner indoor unit. As shown in FIG. 11 , the casing 10 includes a front panel 101 , a front lower panel 102 , a bottom plate 103 , a casing 104 , a frame 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 air outlet 12 is opened in the area where the two connect.
