Detailed ways

The following describes the wall-mounted air conditioner indoor unit according to the embodiment of the present invention with reference to Fig. 1 to Fig. 10. The orientation or positional relationship indicated by "right", "inner", "outer" and so on is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the utility model and simplifying the description, rather than indicating or implying No device or element must have a specific orientation, be constructed and operate in a specific orientation, and thus should not be construed as limiting the invention.

As shown in Fig. 1 to Fig. 4 and Fig. 6, the wall-mounted air conditioner indoor unit according to the embodiment of the present invention includes a housing 10, an evaporator 70, two cross-flow fans, that is, a first cross-flow fan 21 and a second cross-flow fan 22. Two air ducts, ie, the first air duct and the second air duct (only the second air duct 90 on the right is shown in FIG. 6 ) and the sterilization device 72 . The wall-mounted air conditioner indoor unit and the air conditioner outdoor unit together form a vapor compression refrigeration cycle system to cool/heat the indoor environment.

The casing 10 may specifically include a frame 11 , a casing 12 , a left end cover 14 and a right end cover 15 . The skeleton 11 constitutes the main support structure of the indoor unit. The shell 12 is disposed on the outside of the framework 11 . The bottom of the casing 12 is provided with two air outlets 101 arranged side by side along the left and right directions, and the top of the casing 12 is provided with an air inlet 121 . Under the action of two cross-flow fans, the indoor air enters the interior of the housing 10 through the air inlet 121, and after completing heat exchange with the evaporator 70, heat exchange air is formed, and the heat exchange air is blown into the room from the two air outlets 101 for cooling. / heating.

The first air duct and the second air duct are arranged side by side in the casing 10 along the left and right directions, and are respectively used to guide the heat exchanging air after exchanging heat with the evaporator 70 to the two air outlets 101 .

The first cross-flow fan 21 and the second cross-flow fan 22 are cylindrical structures, and their axis lines extend along the left and right directions and are arranged side by side in the two air ducts 90 to match the two air outlets 101 respectively.

The degerming device 72 is installed on the evaporator 70 and is configured to release negative ions and ozone after being energized, so as to remove bacteria and mold in the housing and inhibit the growth of bacteria and mold in the housing. Preferably, the sterilization device 72 and two cross-flow fans are distributed on both sides of the evaporator 70 . For example Fig. 2, evaporator 70 can be three-section evaporator, and it surrounds two cross-flow fans on its inner side), at this moment, sterilizing device 72 can be arranged on the outer surface of evaporator 70, so that two cross-flow fans When the fan sucks air through the evaporator 70, the negative ions and ozone emitted by the sterilization device 72 can pass through the evaporator 70 under the action of suction, so that the evaporator 70 is fully purified.

In some embodiments, the sterilization device 72 can be arranged at one end of the evaporator 70 close to the main control board of the indoor unit of the wall-mounted air conditioner, so as to be electrically connected to the main control board and be powered and controlled by the main control board. For example, as shown in FIG. 2 , the main control board (not shown) is located on the right side of the housing 10, and at this time, the sterilization device 72 is also arranged on the right side of the evaporator 70, so that its wires are connected to the main control board.

In some embodiments, the first air duct and the second air duct are arranged in an offset direction in the front-rear direction, so that the air delivery distances of the two air outlets are different. For example, the position of the first air duct is closer to the front than the position of the second air duct, so that the air supply distance of the first air outlet is longer.

In some embodiments, the axes of the first cross-flow fan 21 and the second cross-flow fan 22 are arranged differently, so that the distances between them and the corresponding air outlets are different. For example, the distance between the first cross-flow fan 21 and the left air outlet 101 can be made smaller than the distance between the second cross-flow fan 22 and the right air outlet 101 .

The wall-mounted air conditioner indoor unit of the utility model can realize multiple air supply modes. The air conditioner can only turn on the first cross-flow fan 21 or the second cross-flow fan 22 according to the air supply requirement when the air supply volume demand is small, so as to reduce fan energy consumption. When the demand for air supply is large, two cross-flow fans can be turned on at the same time to achieve rapid cooling/heating and large air volume cooling/heating.

The embodiment of the utility model realizes the air supply differentiation of the two air outlets. When the distance between the human body and the indoor unit is relatively long, the first cross-flow fan 21 with a long air supply distance can be turned on, and only the air outlet on the left side is used to supply air; The air outlet supplies air. When the distance between the human body and the indoor unit is relatively close, the second cross-flow fan 22 with a short air supply distance can be turned on to make the air outlet on the right supply air.

In some embodiments, the diameter of the first cross-flow fan 21 can be equal to that of the second cross-flow fan 22, and the length of the first cross-flow fan 21 is longer than that of the second cross-flow fan 22, so that at the same speed, the first The air volume of the cross-flow fan 21 is greater than that of the second cross-flow fan 22 . In this way, the air volume of the first cross-flow fan 21 with a relatively long blowing distance is increased, which can facilitate long-distance blowing. The air volume of the second cross-flow fan 22 which is closer to the air supply distance is smaller, which is beneficial to close-distance air supply, and avoids the human body closer to the indoor unit from feeling stronger wind and making the human body uncomfortable.

Both the first air passage and the second air passage are defined by the volute tongue and the volute case located at the rear and lower part of the volute tongue. As shown in FIG. 6 , the second air duct 90 is defined by a volute tongue 91 and a volute case 92 located behind and below the volute tongue 91 . The volute tongue of the first air passage and the volute tongue of the second air passage are arranged in a staggered direction in the front and rear direction, and the volute of the first air passage and the volute of the second air passage are arranged in a staggered direction in the front and rear direction, so that the first air passage The air duct and the second air duct are arranged in an offset direction in the front and rear directions.

In some embodiments, the front edge of the volute (the volute 92 of the second air duct as shown in FIG. 6 ) is connected with an anti-condensation plate 80 extending obliquely to the rear and downward, and the lower edge of the anti-condensation plate 80 is connected to the housing. 90 and a plurality of ribs 801 are formed on its surface.

In this embodiment, when the air conditioner is cooling, when cold air blows out from the air outlet 101 , the temperature of the housing part of the air outlet 101 is relatively low, and the water vapor in the air is likely to condense on the surface of the housing to form condensed water. In order to avoid dripping of condensed water, the ribs 801 provided on the anti-condensation plate 80 can increase the contact area with the cold wind, and the condensed water formed on it can not be condensed into larger water drops due to the barrier of the ribs 801. dripping. Preferably, a plurality of ribs 801 extend along the left and right directions and are parallel to each other, so as to better block the condensed water and prevent the condensed water from flowing down along the grooves formed between two adjacent ribs 801 .

In some embodiments, as shown in FIGS. 1 to 4 , the upper edge of the anti-condensation plate 80 is bent forward and downward to form a rib 82 . When the heat exchange air blows out from the air outlet 101 at a high speed, a negative pressure is formed, and the indoor air can flow along the anti-condensation plate 80 to the heat exchange air under the negative pressure at the air outlet to form a drainage wind, and the drainage wind and heat The exchange winds mix to form a hybrid wind. In this way, during cooling, the temperature of the mixed air is higher than that of the heat-exchanging air, and during heating, the temperature of the mixed air is lower than that of the heat-exchanging air, both of which can make the air flow more comfortable. When the diversion wind encounters the rib 82, it is deflected forward and downward to flow parallel to the heat exchange air, so as to avoid noise caused by its direct impact on the heat exchange air. In addition, the setting of the rib 82 can also keep the mixing area of the heat exchange air and the diversion air away from the indoor unit, which can reduce the condensation on the surfaces of the components of the indoor unit.

In some embodiments, as shown in FIGS. 5 to 7 , the wall-mounted air conditioner indoor unit further includes a bearing component 60 . The left side of the first cross-flow fan 21 is provided with a motor 211 for driving it, and the right side of the second cross-flow fan 22 is provided with a motor 222 for driving it. A motor cover 141 and a motor cover 151 can be installed on the skeleton 11, which are respectively used for installing the motor 211 and the motor 222.

The bearing component 60 is installed on the casing 10 , specifically, the bearing cover 16 can be installed on the skeleton 11 , and the bearing component 60 is installed on the bearing cover 16 . The left end of the bearing component 60 is used for connecting the right shaft of the first cross-flow fan 21 , and the right end of the bearing component 60 is used for connecting the left shaft of the second cross-flow fan 22 .

Specifically, the bearing component 60 may include a bearing with a large axial dimension, and the bearing may be a radial bearing commonly used in the prior art such as a deep groove ball bearing. Or, more preferably, as shown in FIG. 7 , the bearing component 60 may also include a cylindrical housing 61 and two bearings 62 . There are two cylindrical concave cavities 611 at both axial ends of the cylindrical shell 61 (the two cylindrical concave cavities 611 can be arranged asynchronously so that the two cross-flow fans are asymmetrical). The two bearings 62 are installed in the two cylindrical cavities 611 respectively. The two bearings 62 are respectively used to connect the right shaft of the first cross-flow fan 21 and the left shaft of the second cross-flow fan 22 . The cylindrical housing 61 is detachably installed in the bearing housing 16 .

Some other structures may directly use two completely independent bearings to cooperate with the shafts of the two cross-flow fans, but in order to install this structure smoothly, it is necessary to reserve enough operating space between the two bearings. The existence of the space is equivalent to shortening the effective length of the two cross-flow fans. In other words, the air volume of the section of the evaporator corresponding to the operating space is almost zero, which will affect the heat exchange effect of the evaporator. Moreover, the part of the front side of the housing corresponding to the operating space cannot be provided with an air outlet, which indirectly affects the length of the air outlet 101 .

However, in this embodiment, an integral bearing component 60 is used to connect two cross-flow fans. Compared with two independently installed bearings, the integrated bearing component 60 does not need to reserve the above-mentioned operation space. Even if the bearing part 60 includes two bearings 62, the distance between the two bearings 62 can be set to zero. Therefore, the integrated bearing component 60 occupies less space, has less influence on the heat exchange performance of the evaporator 70, and has less influence on the length of the air outlet 101, so that the performance of the whole machine is better. Furthermore, the use of an integral bearing part 60 will undoubtedly simplify the assembly process.

In some embodiments, as shown in FIG. 1 , FIG. 5 , FIG. 8 , and FIG. 9 , the wall-mounted air conditioner indoor unit further includes two air guiding devices 50 . Each air guiding device 50 is arranged at one air outlet 101 for adjusting the air outlet directions of the two air outlets 101 .

The wind deflector 52 is disposed inside an air outlet 101 and is configured to rotate around an axis extending left and right to adjust the up and down wind direction of the air outlet 101 . The shaft 521 at one end of the wind deflector 52 near the middle of the housing 10 is inserted into the shaft hole 112 of the side plate 111 , and the shaft 521 at the other end is connected to a motor 523 for driving the wind deflector 52 to rotate. The swing leaf assembly is arranged inside an air outlet 101 , and includes a plurality of swing leaves 51 . The plurality of swing leaves 51 can swing left and right to adjust the left and right wind direction of the air outlet 101 . Specifically, as shown in FIG. 9 , each swing leaf assembly further includes a connecting rod 53 and a stepping motor. The length direction of the connecting rod 53 extends along the left and right directions, and can reciprocate along the length direction. Different parts of the length direction are respectively hinged with a swing leaf 51, so that when the connecting rod 53 reciprocates along its length direction, it drives a plurality of swing leaves. 51 swing left and right synchronously. The stepping motor is configured to drive the connecting rod 53 to reciprocate along its length. How to convert the rotation of the stepping motor into the translational movement of the connecting rod 53 is generally known in the mechanical field, and will not be repeated here.

The two air guiding devices 50 and the two air outlets 101 can send the wind to two directions, or make one air outlet 101 directional air supply, and the other air supply outlet circulates the wind, or make the air outlets of the two air outlets 101 phased. Mixed to form a mixed flow wind, improving the user's comfort.

The indoor environmental information includes indoor human body surface temperature, human body position information, and The distance between the human body and the indoor unit of the wall-mounted air conditioner is to adjust the wind speed of the first cross-flow fan 21 and the second cross-flow fan 22 and the wind direction of the two air outlets 101 according to the indoor environment information. For example: according to the position of the human body, adjust the direction of the wind so that the cold wind avoids people and the hot wind faces the face. Adjust the wind speed (ie air volume) of the cross-flow fan according to the surface temperature of the human body. Adjust the wind speed (air volume) according to the distance between the human body and the indoor unit of the wall-mounted air conditioner.
