Description

TECHNICAL FIELD

[0001] The present application relates to the field of air conditioning technology, in particular to an air conditioner indoor unit and an air conditioner. BACKGROUND

[0002] The air deflector assembly of the existing air conditioner generally comprises an integral air deflector. The air deflector is driven to rotate by a driving motor. The driving motor drives the air deflector to rotate to a corresponding air outlet direction, so as to realize the change of the air outlet direction.

[0003] Most household air conditioner products have air outlets located at the lower front or the front. The air deflector rotates to guide the air. The adjustable range of the air outlet direction is small. For most air conditioners installed in the scene, when blowing air downward, the air deflector rotates downward at too small an angle. The air conditioner can only blow air obliquely downward and cannot blow air vertically downward. The range of adjusting the air outlet direction is limited. The space of the embedded air conditioner is more limited. The air deflector is limited in upward and downward air deflection. For example, when the embedded air conditioner is installed in an indoor wardrobe, an opening is formed in the front of the indoor wardrobe for the embedded installation of the air conditioner. At this time, the air conditioner can only form an air inlet and an air outlet in the front due to the space limitation of the indoor wardrobe. The upward and downward rotation angles of the existing air deflector are limited, which greatly affects the adjustment of the air outlet direction of the air conditioner. SUMMARY

[0035] The present application provides an air conditioner indoor unit, which can be wall-mounted or embedded. In the prior art, most air conditioner outlets 400 are usually opened in the lower front or front of the air conditioner. Although the space does not limit the outlet 400, the air deflector has a small turning angle, and the outlet direction can only be inclined downward, and the vertical downward direction is not guided by the air conditioner. The outlet direction can be adjusted within a small range. Please refer to Figure 6 When the air conditioner is embedded, the air conditioner can only open the outlet 400 in the front panel facing forward. Due to the limitation of the wall around the outlet 400, the air deflector cannot rotate freely, and the rotation angle range of the air deflector is small, and the adjustment range of the air outlet direction of the air conditioner upward and downward is also reduced. The air conditioner indoor unit provided by the present application can break through the limitation of the wall by the main air deflector assembly 100 extending forward to open the outlet 400, and the sub-air deflector assembly 200 can be moved relative to the main air deflector assembly 100, so that the air direction adjustment angle range is larger. For the convenience of description, the embedded air conditioner indoor unit installed in the wardrobe is taken as an example.

[0036] In the embodiment of the present application, as Figures 1 to 5 shown, the air conditioner indoor unit includes a housing 300 and an air deflector assembly. The housing 300 is provided with an air outlet 400. The air deflector assembly is movably installed at the air outlet 400, and the air deflector assembly includes a main air deflector assembly 100 and a sub-air deflector assembly 200. The main air deflector assembly 100 has a closed position covering the air outlet 400, and an open position opening the air outlet 400 and extending forward from the air outlet 400. The sub-air deflector assembly 200 is installed on the main air deflector assembly 100, and the sub-air deflector assembly 200 is movable relative to the main air deflector assembly 100, so that the air flow direction through the air deflector assembly can be adjusted.

[0037] The shell 300 comprises a bottom disc, a cross-flow fan, a fan motor, an electric control box, a heat exchanger, a front panel, a display box and a plurality of components, which will not be described here. The cross-sectional shape of the air outlet 400 can be circular, oval, polygonal, etc., which can be selected according to requirements. The air deflector assembly is installed at the air outlet 400, and the user can adjust the position of the air deflector assembly to guide the airflow direction of the air outlet 400, thereby improving comfort. The main air deflector assembly 100 can be rectangular, square, cylindrical, regular or irregular, which is not limited here. The sub-air deflector assembly 200 can be rectangular, arc-shaped, polygonal, regular or irregular, which is not limited here. The sub-air deflector assembly 200 can be installed on the inner side of the main air deflector assembly 100 or on the outer side of the main air deflector assembly 100, as long as it can rotate relative to each other without air leakage.

[0038] As shown in Figure 7 In this embodiment, the main air deflector assembly 100 can completely cover the air outlet 400 or open the air outlet 400 forward. When the air conditioner is in the closed state, the main air deflector assembly 100 completely covers the air outlet 400 to prevent dust or debris from running into the air conditioner and affecting the use of the air conditioner. The sub-air deflector assembly 200 converges in the air conditioner. When the air conditioner is turned on, the main air deflector assembly 100 extends forward to release the airflow of the air outlet 400. The sub-air deflector assembly 200 can move with the main air deflector assembly 100, and the sub-air deflector assembly 200 can move relative to the main air deflector assembly 100, that is, the sub-air deflector assembly 200 is not fixed on the main air deflector assembly 100. The sub-air deflector assembly 200 has an air deflection function, which can move relative to the main air deflector assembly 100 to adjust the air outlet direction, so that the airflow hits the sub-air deflector assembly 200 to change the flow direction. Compared with the existing air deflector assembly, the rotation angle range is wider. In this way, the embedded air conditioner indoor unit can be free from the restriction of the surrounding wall due to the forward extension of the main air deflector assembly 100, and the direction adjustment of the sub-air deflector assembly 200 greatly increases the adjustable range of the air supply direction.

[0039] The present application realizes multiple air outlet guiding states by setting a composite air deflector assembly at the air outlet 400, and the rotation angle of the main air deflector assembly 100 and the sub-air deflector assembly 200 is matched, which can adapt to various installation scenes, free from the restriction of space on the air outlet 400, cover multiple air outlet directions, and meet the use requirements of users.

[0040] Please refer to Figure 5In the embodiment, the main air deflector assembly 100 comprises the air deflector 120 and the two end plates 110, and the two ends of the air deflector 120 are connected to the two end plates 110 respectively. It can be understood that the air deflector 120 can be used to close and open the air outlet 400, and the two end plates 110 play a supplementary role. When the air conditioner indoor unit is opened, the main air deflector assembly 100 extends forward, a part of the main air deflector assembly 100 is out of the space limitation of the shell 300 and is exposed, and the two end plates 110 can prevent air flow from running out from the two sides. When the air conditioner indoor unit is closed, the air deflector 120 covers the air outlet, and the two end plates 110 contact the inner side surfaces of the air duct on the two sides of the air conditioner indoor unit, so that the outer surface of the air conditioner indoor unit is flat and the surface is beautiful. The auxiliary air deflector assembly 200 is installed in the main air deflector assembly 100 in the mounting mode of the two end plates 110, which can be rotatable or translatable, as long as it can be adjusted to adjust the air outlet direction on the main air deflector assembly 100. In the embodiment, the auxiliary air deflector assembly 200 is rotatably installed on the two end plates 110. In this way, the driving mode is easy to implement, the structure is simple, and the air deflection effect is good.

[0041] The main driving device can be installed on the shell 300 or the main air deflector assembly 100. In order to facilitate driving the main air deflector assembly 100, refer to Figure 1 In the embodiment, the air conditioner indoor unit further comprises a main driving device, the main driving device is installed on the shell 300, and the main driving device drives the main air deflector assembly 100. The main driving device can drive the main air deflector assembly 100 to extend forward to open the air outlet 400 and close the air outlet 400. The main driving device can comprise a motor, an electromagnet and the like driving member, or can comprise a gear, a rack, a turbine, a worm and the like transmission member. As long as it can drive the main air deflector assembly 100 to rotate to the required rotation angle to open and close the air outlet 400.

[0042] In combination with the above embodiments, further, the main driving device comprises a first motor 150 and a first driving gear 140 mounted on the first motor 150, wherein one of the end plates 110 is fixed with a first driven gear 130, and the first driving gear 140 is engaged with the first driven gear 130. The first motor 150 can be a step motor, which can facilitate the control of the rotation amount of the main air deflector assembly 100. The first driven gear 130 can be fixed on one end plate 110 or on both end plates 110, as long as it can drive the main air deflector assembly 100 to rotate. In this embodiment, one of the end plates 110 is fixed with the first driven gear 130. The first driven gear 130 directly drives the main air deflector assembly 100 to rotate, and its direction and rotation amount are consistent with those of the main air deflector assembly 100. For example, if the first driven gear 130 rotates 90 degrees clockwise, the main air deflector assembly 100 also rotates 90 degrees around its rotation axis. The driving structure of the first motor 150, the first driving gear 140 and the first driven gear 130 is simple and reliable, has a long service life and high precision.

[0043] The first driven gear 130 can be a complete gear, an incomplete gear or a sector gear, as long as it can make the main air deflector assembly 100 extend forward. Figure 2 and Figure 5In the embodiment, the first driven gear 130 is a 1 / 6 to 1 / 3 sector gear, the first driven gear 130 is provided with a first limiting pin 131, the shell 300 is provided with a first limiting groove 133 arranged in an arc shape, and the first limiting pin 131 extends into the first limiting groove 133. It can be understood that the first driven gear 130 can be a 1 / 6 sector gear, a 1 / 4 sector gear, or a 1 / 3 sector gear, as long as it can meet the angle at which the first driven gear 130 drives the main deflector assembly 100 to turn, and the specific limitation is not made here. For example, the first driven gear 130 is a 1 / 4 sector gear, which is equivalent to a 1 / 4 sector gear with an arc of 90 degrees, and the first driven gear 130 can rotate by 90 degrees, i.e., the main deflector assembly 100 can rotate by 90 degrees. The sector gear can not only realize the transmission of the main deflector assembly 100 rotation, but also has the advantages of smaller occupied area, smaller volume, and lower manufacturing cost. The shape of the first limiting pin 131 can be rectangular, spherical, cylindrical, etc. The shape of the first limiting groove 133 can be a rectangular limiting groove, an arc limiting groove, a spherical limiting groove, etc., as long as the first limiting groove 133 and the first limiting pin 131 are matched and limit the range of movement of the first limiting pin 131. The first limiting pin 131 extends into the first limiting groove 133 to stop the rotation of the first driven gear 130, and their cooperation limits the movement range of the main deflector assembly 100, preventing the main deflector assembly 100 from contacting and colliding with other parts of the air conditioner indoor unit to damage the shape of the main deflector assembly 100 and cause deformation. Such an arrangement not only prolongs the service life of the deflector assembly, but also simplifies the manufacturing process, reduces manufacturing costs, and ensures the operation effect of the air conditioner, improving user satisfaction.

[0044] Further, referring to Figure 5 , the main deflector assembly 100 is provided with a second limiting pin, the first driven gear 130 is provided with a second limiting groove 134 arranged in an arc shape, and the second limiting pin extends into the second limiting groove 134. The shape of the second limiting pin can be rectangular, spherical, cylindrical, etc. The shape of the second limiting groove 134 can be a rectangular limiting groove, an arc limiting groove, a spherical limiting groove, etc. Through the double action of the first limiting pin 131 and the second limiting pin, the first driven gear 130 is more stable, an additional limiting insurance is added, and the movement range of the main deflector assembly 100 is controlled to improve the stability of the whole machine operation. At the same time, the second limiting groove 134 can also reduce the weight of the first driven gear 130 itself, save materials, and reduce production costs.

[0045] In the embodiment, the first limiting groove 133 and the second limiting groove 134 are both arranged in an arc shape. The arc line displacement of the first limiting pin 131 and the second limiting pin needs to be limited, and the arc line movement is limited, which is equivalent to limiting the degree of the forward extension of the main guide vane assembly 100, and ensuring the stable operation of the entire transmission mechanism. The two limiting grooves in the circular arc shape are matched with the movement tracks of the two limiting pins, and the assembly position can be judged by appearance during assembly of the workers, and the structure is simple and easy to understand, and the process is simple.

[0046] The circular arc radian of the first limiting groove 133 and the second limiting groove 134 can be 90 degrees, 100 degrees, 110 degrees, 120 degrees, etc., as long as the main guide vane assembly 100 can be turned to the preset position to improve the guide effect. For example, the circular arc radian is 120 degrees, please refer to Figure 7 When the air conditioner is turned off, the guide vane 120 covers the air outlet 400, and the main guide vane assembly 100 is collected in the air conditioner indoor unit, and the main guide vane assembly 100 is in the limit state and can only be turned forward to open the air outlet 400. The limit value of the inclination angle of the main guide vane assembly 100 when it is turned forward and upward at this time is 120 degrees. It can be understood that if the circular arc radian is less than 90 degrees, the turning angle of the main guide vane assembly 100 is not enough when the air conditioner blows upward, the upward guide effect of the guide vane assembly is not obvious, and the comfort of the air conditioner is reduced.

[0047] Please refer to Figure 4 , the air conditioner indoor unit further comprises a secondary driving device, the secondary driving device is installed on the main guide vane assembly 100, and the secondary driving device is drivingly connected with the secondary guide vane assembly 200. The secondary driving device can drive the secondary guide vane assembly 200 to rotate with the main guide vane assembly 100, so as to realize the rotation adjustment of the secondary guide vane assembly 200 to adjust the air outlet direction. The secondary driving device can include a motor, an electromagnet and the like driving member, and can also include a gear, a rack, a turbine, a worm and the like transmission member. Only the secondary guide vane assembly 200 can be driven to rotate to adjust the air outlet direction.

[0048] In combination with the above embodiment, further, the secondary driving device comprises a second motor 250 and a second driving gear 240 installed on the second motor 250, one of the end plates 110 is provided with a second driven gear 230, the second driven gear 230 is rotatable relative to the end plate 110, the secondary guide vane assembly 200 is connected with the second driven gear 230, and the second driving gear 240 is engaged with the second driven gear 230.

[0049] The second motor 250 can be a stepper motor, which can better control the relative rotation amount of the auxiliary air deflector assembly 200. The second driven gear 230 can be mounted on one end plate 110 or on both end plates 110, as long as it can drive the auxiliary air deflector assembly 200 to rotate. The second driven gear 230 can rotate relative to the end plate 110, that is, relative to the main air deflector assembly 100. The second driven gear 230 can drive the auxiliary air deflector assembly 200 to rotate, that is, the auxiliary air deflector assembly 200 can rotate relative to the main air deflector assembly 100. In this way, in combination with the opening of the main air deflector assembly 100 to the front of the air outlet 400, the auxiliary air deflector assembly 200 adjusts the air outlet direction, effectively increasing the range of the air outlet direction that can be adjusted. The transmission structure of the second motor 250, the second driving gear 240 and the second driven gear 230 is used to adjust the air outlet direction, which is more simple and reliable in transmission, more accurate and has a long service life.

[0050] In order to prevent the gears from disengaging and affecting the stability and effectiveness of the entire air deflector assembly, in this embodiment, the first driving gear 140 is engaged with the first driven gear 130, and the second driving gear 240 is engaged with the second driven gear 230. It can be understood that if the gears are not engaged or the engagement amount is small, the noise and vibration during gear transmission will be large, the service life will be reduced, and in severe cases, the tooth surface will be broken and fail prematurely, resulting in paralysis of the entire air deflector assembly and reducing the user's experience of using the air conditioner.

[0051] Further, please refer to Figure 4 , the second driven gear 230 is an incomplete gear, one of the end plates 110 is provided with a limiting column 231, and the limiting column 231 is used to limit the rotation amplitude of the second driven gear 230. The second driven gear 230 has incomplete protrusions, leaving a part of the non-protrusion area. The shape of the limiting column 231 can be rectangular, cylindrical, spherical, etc., as long as it can block the rotation of the second driven gear 230. Through the cooperation of the non-protrusion area of the second driven gear 230 and the limiting column 231, when the auxiliary air deflector assembly 200 rotates relative to the main air deflector assembly 100, the limiting column 231 can limit the rotation angle of the auxiliary air deflector assembly 200, preventing the auxiliary air deflector assembly 200 from being deformed or broken under stress, and the cooperation mode of the second driven gear 230 and the limiting column 231 is simple and reliable and easy to implement.

[0052] At present, many air deflector air deflection, air conditioner air can only be thrown through the straight air deflector, the air flow range is short and the air deflection direction is not accurate. Please refer to Figures 7 to 10In the embodiment, the auxiliary air deflector assembly 200 comprises an arc segment 220 and a straight segment 210, and the straight segment 210 connects the arc segment 220. It can be understood that the air blown by the air conditioner is guided along the arc surface to change the wind direction, and can be thrown along the relatively flat surface, greatly increasing the range of the air deflector blowing, and forming weak and comfortable air conditioner wind at a distance. In this way, the distance of air blowing is expanded only by changing the shape, the structure is simple, the production process is simple, and it is easy to realize.

[0053] Please refer to Figures 8 to 10 In the embodiment, when the main air deflector assembly 100 opens the air outlet 400, the air conditioner indoor unit has a direct blowing mode, a warm air mode and a direct blowing prevention mode; in the direct blowing mode, the flow guide plate 120 is inclined downward, the concave arc surface of the arc segment 220 faces downward, and the straight segment 210 extends downward to guide the airflow to blow directly on the human body; in the warm air mode, the flow guide plate 120 extends forward, the concave arc surface of the arc segment 220 faces backward, and the straight segment 210 extends downward to guide the airflow to flow downward; in the direct blowing prevention mode, the flow guide plate 120 is inclined upward, the concave arc surface of the arc segment 220 faces downward, and the straight segment 210 extends upward to guide the airflow to flow upward obliquely.

[0054] Specifically, when the air conditioner is closed, the entire main guide panel assembly 100 is received in the air conditioner, the guide plate 120 covers the air outlet 400, the two end plates 110 are also received in the air conditioner, the secondary guide panel assembly 200 is also received in the air conditioner, the arc segment 220 has a concave arc surface facing the rear, and the straight line segment 210 is inclined upward to prevent dust from entering and affecting the operation effect of the entire machine. When the user uses the air conditioner, the air conditioner has three modes with different wind directions, including a straight blowing mode of blowing cold air obliquely downward, a straight blowing prevention mode of blowing cold air obliquely upward, and a warm air mode of blowing warm air downward, which can be selected according to requirements. In the straight blowing mode, the air conditioner blows air directly to the human body, and the user can feel cooler; in the straight blowing prevention mode, the cold air is guided upward, and the wind direction is adjusted considering that the user is weak and is worried about catching a cold by the straight blowing cold air; in the warm air mode, the warm air is blown downward, and the hot air is lighter and runs upward, so that the room is better warmed. When the air conditioner is in the straight blowing mode, the secondary guide panel assembly 200 faces the inside of the air outlet 400 and is lapped on the inner bottom wall of the air outlet air duct of the air conditioner to intercept the airflow from running out from below, and the main guide panel assembly 100 is inclined outward and downward between the secondary guide panel assembly 200 to define an air outlet channel to guide the airflow to run out obliquely downward and blow to the human body. This blowing mode blows air directly to the human body, so that the user feels faster air flow and cooler air. When the air conditioner is in the warm air mode, the main guide panel assembly 100 faces forward, and the secondary guide panel assembly 200 is lapped on the guide plate 120, so that the airflow changes direction downward along the arc segment 220 and is thrown along the straight line segment 210. Thus, the air is sent downward at a long distance and in a direction, which is different from the general downward air sending. In the embodiment, the downward air sending angle is more vertical, the blowing angle range is larger, and the blowing area covered is wider. In the straight blowing prevention mode, the main guide panel assembly 100 is inclined upward, and the secondary guide panel assembly 200 is lapped on the inner bottom wall of the air outlet air duct of the air conditioner to prevent the airflow from running out from below, and the airflow is blown obliquely upward by the guiding effect, so that the cold air does not blow directly to the human body and the refrigeration process is more gentle.

[0055] Compared with the existing air conditioner indoor unit, the air conditioner indoor unit of the present application breaks the limitation of space on the air outlet direction, and can greatly increase the adjustable range of the air outlet direction of the air conditioner and realize directional air sending in different guide modes. When the air conditioner is in a non-closed state, the main guide panel assembly 100 is turned outward, the airflow of the air outlet 400 exchanges heat with the surrounding air, the temperature difference between the air conditioner air and the surrounding air is not large, so that the comfort is improved when the air is blown to the human body after being guided.

[0056] The present application also provides an air conditioner, which comprises an air conditioner indoor unit connected with an air conditioner outdoor unit through a refrigerant pipe. The specific structure of the air conditioner indoor unit is the same as that of the above-mentioned embodiments. Since the air conditioner indoor unit adopts all the technical solutions of the above-mentioned embodiments, it has all the beneficial effects of the technical solutions of the above-mentioned embodiments, which will not be repeated here.

[0057] The above merely describes optional embodiments of the present application, and does not limit the patent scope of the present application. Any equivalent structural transformation, direct / indirect application in other related technical fields, or the like, made under the inventive concept of the present application, using the content of the present application specification and drawings, are included in the patent protection scope of the present application.
