Example Embodiment

[0058] This embodiment first provides a wall-mounted air conditioner indoor unit 100, figure 1 It is a schematic structural diagram of the wall-mounted air conditioner indoor unit 100 according to the first embodiment of the present invention, in which the wind deflector 150 is in the first position.

[0059] See figure 1 The wall-mounted air conditioner indoor unit 100 may generally include a housing 110, an indoor unit heat exchanger 120 and an indoor unit fan 130 disposed in the housing 110. The top of the housing 110 is formed with a top air inlet 111, the lower part of the housing 110 is formed with an air outlet extending in the transverse direction of the indoor unit 100, and an air outlet 140 communicating with the air outlet is provided inside the housing 110, and the air outlet The passage 140 is defined by an upper air passage wall 141 and a lower air passage wall 142. The indoor unit heat exchanger 120 may be configured to exchange heat with the air flowing therethrough, so as to change the temperature of the air flowing therethrough to make it into heat exchange air. The indoor unit fan 130 can be configured to cause the indoor air entering from the top air inlet 111 to flow to the indoor unit heat exchanger 120, and to cause the heat exchange air after the heat exchange by the indoor unit heat exchanger 120 to go to the air outlet through the air outlet duct 140 flow. The lateral direction refers to the longitudinal extension direction of the indoor unit 100.

[0060] In particular, the wall-mounted air conditioner indoor unit 100 of this embodiment further includes a wind deflector 150, which includes an upper plate section 151 and at least one lower plate section 152 connected to the lower portion of the upper plate section 151. The air deflector 150 has a first position to retract the air outlet duct 140 and a second position to move out of the air duct 140. The air deflector 150 is configured to move in controlled translation between the first position and the second position, and When the air deflector 150 moves from the first position to the second position, the air outlet is exposed. When the air deflector 150 is in the first position, the lower plate section 152 located at the bottom covers the air outlet, and the upper plate section 151 or the upper plate The plate section 151 and the remaining lower plate sections 152 are located in the air outlet duct 140; and when the air guide plate 150 is in the second position, the upper plate section 151 is configured to be controlled to rotate around a first axis parallel to the extension direction of the air outlet , And drive all the lower plate sections 152 connected to the lower part of the upper plate section 151 to rotate to adjust the direction and area of the wind.

[0061] After the wind deflector 150 moves out of the air outlet duct 140 in translation, the wind deflector 150 can be rotated to a number of different positions to adjust the wind direction and the wind area under different conditions. The wind deflector 150 can stay at any position of its translation path during the translation process between the first position and the second position, thereby realizing that the wind deflector 150 can also adjust the direction of the wind during the translation process. Adjust the air outlet area. As a result, the air-conditioning indoor unit 100 of the present invention can reasonably adjust the air outlet direction and the air outlet area according to its different operating conditions, increase the diversity of the air, meet the diverse needs of users, and improve the comfort of users.

[0062] Before the air deflector 150 translates from the second position to the first position, the air deflector 150 is configured to rotate to an initial position where the lower plate section 152 located at the bottom is directly opposite to the position of the air outlet, that is, Before the air deflector 150 is retracted from the second position outside the air outlet air duct 140 to the first position of the air outlet air duct 140, the air deflector 150 first needs to be rotated from the current position state to The lower plate section 152 of the wind deflector 150 at the lowermost position is directly opposite to the position of the air outlet. This position is recorded as the initial position of the wind deflector 150 in the second position. After the wind deflector 150 rotates to the initial position, Then retract into the air outlet duct 140 in translation, so as to ensure that when the air deflector 150 moves into the air outlet 140 in a translational motion, the lower plate section 152 of the air deflector 150 at the lowermost portion just covers the air outlet.

[0063] In the actual operation of the air-conditioning indoor unit 100, after receiving a control instruction for the air deflector 150 to move to the first position, it first detects the position state of the air deflector 150 at this moment. If the position state of the air deflector 150 at this moment is not the initial position, then The air deflector 150 is controlled to rotate to the initial position, and then retracts to the outlet air duct 140 in translation; if the position of the air deflector 150 at the moment is the initial position, the air deflector 150 directly retracts into the air outlet 140 in translation .

[0064] The above-mentioned operating state and position state of the air deflector 150 of the air-conditioning indoor unit 100 can be realized by a remote control, which is convenient for the user to reasonably adjust the position of the air deflector 150 according to their own needs to obtain a more comfortable air supply effect.

[0065] In an embodiment of the present invention, there is one lower plate section 152. It can be understood that the upper plate section 151 and the lower plate section 152 may extend along the length of the air outlet, and the upper plate section 151 and the lower plate section 152 may extend from one end to the other end of the air outlet in the length direction.

[0066] The width of the lower plate section 152 may be approximately the same as the width of the air outlet, so that when the air deflector 150 is retracted into the air outlet duct 140, the lower plate section 152 can just shield the air outlet, and the outer surface of the lower plate section 152 It is flush with the bottom end of the housing 110, so that the appearance of the air outlet is more beautiful when the air outlet is closed.

[0069] The straight L-shaped wind deflector 150 or the oblique L-shaped wind deflector 150 can better control the airflow direction, and when the wind deflector 150 is in different positions, there are different air supply conditions, for example, Figure 4 As shown, when the straight L-shaped air deflector 150 is in the initial position of the second position, it can achieve flat blowing, which is beneficial for cooling; if the straight L-shaped air deflector 150 rotates upward from the initial position, it can achieve upward blowing, which is beneficial for cooling. At the same time, the problem of poor experience caused by cold wind blowing directly on the human body is avoided; if the straight L-shaped wind deflector 150 rotates downward from the initial position, downward blowing can be achieved, which is beneficial for heating. Therefore, by adjusting the position of the straight L-shaped wind deflector 150, it can achieve a large cooling upward blowing angle, a wide range, a small air volume loss, and a large heating downward blowing angle, a high wind speed, and a longer air supply distance. The heat exchange speed is fast, so as to achieve a better air supply effect and make the cooling and heating comfort experience better.

[0070] Such as figure 2 As shown, when the inclined L-shaped wind deflector 150 is in the initial position of the second position, it can realize flat blowing or upward blowing, which is good for cooling; if the inclined L-shaped wind deflector 150 rotates upward from the initial position, it can realize upward blowing, which is beneficial to Refrigeration; if the inclined L-shaped wind deflector 150 rotates downward from the initial position, downward blowing can be achieved, which is beneficial for heating. Therefore, by adjusting the position of the inclined L-shaped wind deflector 150, it can achieve a large cooling upward blowing angle, a wide range, a small air loss, and a large heating downward blowing angle, a high wind speed, and a longer air supply distance can be achieved in the room. The heat exchange speed is fast, so as to achieve a better air supply effect and make the cooling and heating comfort experience better.

The long plate 160 is formed with a first rack section 160a extending along the extending direction of the long plate 160 for meshing with the gear 171, and the upper plate section 151 is formed at a position adjacent to the first rack section 160a for meshing with the gear 171 The second rack section 151a of the gear 171 drives the wind deflector 150 and the at least one long plate 160 to move in translation through the first rack section 160a and the second rack section 151a.

[0093] For inclined L-shaped wind deflector 150 or straight L-shaped wind deflector 150, such as Picture 10 As shown, the air conditioner indoor unit 100 further includes a second motor 170. The second motor 170 is disposed on the upper plate section 151 and has a second output shaft connected to the upper plate section 151 and parallel to the first axis of the air deflector 150. . When the wind deflector 150 is in the second position, the second motor 170 drives the upper plate section 151 to rotate around the axis, and the rotation of the upper plate section 151 drives the lower plate section 152 to rotate synchronously.

[0094] For the air deflector 150 that is rotatably connected to the lower plate section 152 and the upper plate section 151, such as Figure 13 As shown, the air conditioner indoor unit 100 further includes a second motor 170 and a third motor 172. The second motor 170 is disposed on the upper plate section 151 and has a second output shaft connected to the upper plate section 151 and parallel to the first axis on which the wind deflector 150 rotates. When the wind deflector 150 is in the second position, the second motor 170 drives the upper plate section 151 to rotate around the axis, and the rotation of the upper plate section 151 drives the lower plate section 152 to rotate synchronously. The third motor 172 is arranged on the lower plate section 152 and has a third output shaft connected to the lower plate section and parallel to the second axis. When the wind deflector 150 is in the second position, the third motor 172 drives the lower plate section 152 Rotate independently.

[0095] When the air deflector 150 is in the first position, the gear 171 is in a state of meshing with the second rack section 151a, and when the air deflector 150 is in the second position, the gear 171 is in a state of meshing with the first rack section 160a. The same end of the first rack section 160a and the second rack section 151a adjacent to the upper side of the upper plate section 151 satisfy: when the wind deflector 150 rotates to the initial position (the initial position of the second position described above) , The second rack section 151a is located in the extension direction of the first rack section 160a, and during translation of the wind deflector 150 and the at least one long plate 160, the second rack section 151a and the first rack section 160a meet Before the gear 171 is disengaged from the second rack section 151a, the gear 171 meshes with the first rack section 160a, thereby ensuring that the gear 171 always meshes with the first rack section 160a or the second rack section 151a to ensure air guidance Continuous translation of the plate 150 and the at least one elongated plate 160.

[0096] There are two long plates 160 and two driving mechanisms. The two long plates 160 respectively extend upward from the positions of the two ends of the upper side of the upper plate section 151 adjacent to the upper side, and are arranged oppositely; The first motors are respectively arranged at two ends of the housing 110 in the transverse direction, and are arranged oppositely.

[0097] In particular, such as Figure 10 to Figure 14 , The inner surface of the upper plate section 151 includes a fourth plane section 151-2 and a mixed plane section connected in sequence from the upper side to the lower side of the upper plate section 151, the fourth plane section 151-2 and the upper plate section 151 The outer surfaces 151-1 are parallel. The mixed surface segment is composed of a fourth circular arc surface segment 151-3 in the middle and two fifth planar segments located at both ends of the fourth circular arc surface segment 151-3 in the transverse direction, and two fifth planar segments and a fourth plane The segments 151-2 are in the same plane, and the fourth arcuate surface segment 151-3 is recessed in the direction of the outer surface 151-1 of the upper plate segment 151.

[0098] The two first rack segments 160a are respectively formed on the inner surfaces of the two long strip plates 160, and the two second rack segments 151a are respectively formed at the positions of the fourth plane segment 151-2 corresponding to the corresponding long strip plates 160, And each second rack segment 151a extends to the fifth plane segment corresponding to the fourth plane segment 151-2. That is to say, the second rack section 151a is formed at the position corresponding to the fifth plane section and the fourth plane section 151-2, such as Figure 4 to 6 As shown, a section of the second rack section 151a is formed in the fifth plane section, and the other section of the second rack section 151a is formed at a position corresponding to the fourth plane section 151-2 and the fifth plane section.

[0099] The outgoing air flow flows along the fourth plane section 151-2 and the fourth arc surface section 151-3 of the upper plate section 151 in sequence, and guides the air flow to the lower plate section 152 through the fourth arc surface section 151-3. On the inner surface, the airflow flows along the inner surface of the lower plate section 152, and the structure of the inner surface of the lower plate section 152 is as described in the above-mentioned embodiment, and will not be repeated here. The fourth plane section 151-2 maintains the flow direction of the outflow airflow, and the fourth arcuate plane section 151-3 changes the flow direction of the airflow guided by the fourth plane section 151-2, so that the outflow airflow flows smoothly, which is beneficial to control Airflow direction, and avoid airflow confusion, reduce air volume loss.

[0100] Moreover, by forming a first rack section 160a on the inner surface of the long plate 160, a second rack section 151a is formed on the upper plate section 151, and the gear 171 is driven by the first rack section 160a and the second rack section 151a The wind deflector 150 moves in translation between the first position and the second position, which simplifies the drive design for realizing the translation and rotation of the wind deflector 150 (the driving design mentioned here includes the driving mechanism, the elongated plate 160, and the first tooth The section 160a and the second rack section 151a) make the entire drive design compact and exquisite, which facilitates the translation of the air deflector 150 in the indoor unit 100 with a small space, and ensures that the air deflector 150 is in the second position Stable rotation at time.

[0101] The housing 110 may include two end boxes 180 located at two ends in the lateral direction of the housing 110, and each driving mechanism may also include a guide rail 190, and the guide rails 190 and the first motor of the same driving mechanism are arranged at the same end. In the box 180, the extending direction of the guide rail 190 is consistent with the translational direction of the long strip 160 and the wind deflector 150. When the first motor is under controlled operation, the two long strips 160 respectively move along the corresponding guide rails 190 to keep The stability of the wind deflector 150 in translation.

[0102] Both end boxes 180 are formed with avoidance notches 181 penetrating the air outlet 140, and the two avoidance notches 181 are arranged oppositely, and the extension direction of the avoidance notches 181 is parallel to the translational direction of the long strip 160 to avoid the two Each end box 180 interferes with the translation of the strip 160 and the wind deflector 150.

[0103] The wall-mounted air-conditioning indoor unit 100 of this embodiment changes the position of the air guide plate 150 at the air outlet by adjusting the rotation position of the upper plate section 151 and the lower plate section 152 to realize the adjustment of different air supply modes, which is convenient to adjust according to the indoor unit 100 operating conditions flexibly adjust the air supply mode to meet the diverse needs of users and improve user experience. In addition, the adjustment of the position of the air deflector 150 can better control the airflow direction, achieve the effects of large cooling upward blowing angle, wide range, and small air volume loss, and can achieve large heating downward blowing angle, high wind speed, and air supply distance. Farther, fast heat exchange in the room and other effects. As a result, a better air supply effect is achieved, and the cooling and heating comfort experience is better.

[0104] In addition, in the air conditioner indoor unit 100 of this embodiment, the upper plate section 151 is formed with a first air dissipating hole 151d, and the lower plate section 152 is formed with a second air dissipating hole 152b. The airflow can pass through the first air dissipating hole 151d and the The second air vent 152b blows out to form a breeze airflow, which reduces the speed and volume of the air outlet, so that the user can always feel a slight wind blowing. The indoor unit 100 will not make the user feel under the cooling condition When the temperature is too low, the user comfort is improved.

[0105] In one of the embodiments of the present invention, see again figure 2 The housing 110 includes a top plate and a rear inclined plate. The top plate is arranged in a substantially horizontal direction. The rear inclined plate is connected to the rear edge of the top plate and extends backward and downward from the rear edge of the top plate. A top air inlet 111 is formed on the top plate, a rear air inlet 112 is formed on the rear inclined plate, and an air outlet is formed on the bottom of the housing 110. The indoor air enters the indoor unit 100 through the top air inlet 111 and the rear air inlet 112, and after heat exchange with the indoor unit heat exchanger 120, flows out of the indoor unit 100 through the air outlet duct 140 and enters the room, thereby adjusting the indoor temperature.

[0106] The indoor unit heat exchanger 120 includes a first heat exchange section 121, a second heat exchange section 122, and a third heat exchange section 123 connected in sequence. The first heat exchange section 121 is located in front of the rear air inlet 121 and extends backward and downward. The second heat exchange section 122 communicates with the first heat exchange section 121 and extends forward and downward from the top of the first heat exchange section 121 , The third heat exchange section 123 communicates with the second heat exchange section 122, and extends vertically downward from the bottom of the second heat exchange section 122.

[0107] For the traditional wall-mounted air conditioner indoor unit 100, the top-inlet mode is generally adopted, that is, the indoor unit 100 has a top air inlet 111, and the air outlet of the indoor unit 100 is located at the lower front side of the housing 110. The airflow that exchanges heat with multiple heat exchange sections in the shell 110 all enters through the top air inlet 111, which causes the heat exchange section close to the top air inlet 111 to directly exchange heat with the airflow entering through the top air inlet 111 , And the heat exchange airflow from other heat exchange sections away from the top air inlet 111 needs to pass through a relatively long and narrow area before reaching these heat exchange sections. The flow of airflow that needs to pass through a relatively narrow and long area will cause unnecessary airflow friction and pressure loss, and correspondingly, there will be adverse effects such as increased noise and reduced air volume, and the vertical air inlet angle is single, resulting in airflow reaching the indoor unit heat exchanger If the turning angle of 120 is too large, undesirable pulsation of the air flow will occur, which will affect the stability of the flow field in the indoor unit fan 130.

[0108] In this embodiment, by forming air inlets on both the top plate and the rear sloping plate, the air inlet mode is redistributed, and the third heat exchange section 123 and the second heat exchange section 122 exchange heat with the air flow entering through the top air inlet 111 , The first heat exchange section 121 exchanges heat with the airflow entering through the rear air inlet 112, the airflow distribution is reasonable, the air inlet area is enlarged, the airflow friction is reduced, the airflow distribution is more uniform, and the airflow head of the first heat exchange section 121 is obvious Reduced, the air inlet angle is more reasonable, and the air-conditioning noise is effectively reduced.

[0109] The width of the top plate is 1/5 to 1/2 of the width of the housing 110. Optionally, the width of the top plate is 3/10 to 4/10 of the width of the housing 110. The ratio of the width of the top plate to the width of the housing 110 is in the range of 1/5 to 1/2, or in the range of 3/10 to 4/10. Therefore, the ratio of top air intake and rear air intake can be further adjusted, and the air intake volume and angle of the different heat exchange sections of the indoor unit heat exchanger 120 in the cabinet can be more reasonably distributed. Under the premise of ensuring the air intake volume, the air flow The distribution is reasonable, the distribution is more even, the air friction is reduced, and the noise of the indoor unit 100 is effectively reduced.

[0110] The bottom end of the rear sloping plate intersects with the vertical line passing through the highest point of the down duct wall 142 as a tangent to the down duct wall 142, and the angle between the rear sloping plate and the horizontal plane can be 25° to 45°. This defines the position where the rear slope extends from the rear edge of the top plate to the rear and downwards, so as to reasonably adjust the ratio of the top air inlet 111 and the rear air inlet 112, and reasonably allocate the second heat exchange section 122 and the third heat exchange section 123. Inlet air volume and air inlet angle, and solve the air inlet problem of the first heat exchange section 121. Under the premise of ensuring the air inlet volume, increase the air inlet area, reduce the air resistance, reduce the air head, and effectively reduce the air conditioning noise.

[0111] It is understandable that, in this article, words such as "upper", "lower", "front", "rear" and other words indicating the orientation or positional relationship are based on the state of the indoor unit 100 when it is hung on the wall in actual use, and "inside" "" refers to the side facing the front of the indoor unit 100, and "outside" refers to the side facing the rear of the indoor unit 100. "Front" refers to the direction away from the wall, and "rear" refers to the direction close to the wall.

[0112] In the wall-mounted air conditioner indoor unit 100 of this embodiment, the air guide plate 150 can be moved in a controlled translation between the second position where the air duct 140 is moved out and the first position where the air duct 140 is retracted. 150 includes an upper plate section 151 and at least one lower plate section 152 connected to the lower part of the upper plate section 151. After the air deflector 150 is moved out of the air duct 140, the air deflector can rotate around an axis parallel to the extending direction of the air outlet, thereby Adjusting the air outlet volume and direction of the indoor unit 100 can achieve better air supply and meet the diverse needs of users.

[0113] Further, in the wall-mounted air conditioner indoor unit 100 of this embodiment, the lower plate section 152 of the air deflector 150 has a special shape and structure, which can better control the airflow direction, reduce air volume loss and keep the airflow flowing smoothly.

[0114] Furthermore, in the wall-mounted air conditioner indoor unit 100 of this embodiment, a long plate 160 connected to the upper plate section 151 is provided, and a first rack section 160a is formed on the long plate 160. A second rack section 151a is formed on the 151. The gear 171 drives the wind deflector 150 to move between the first position and the second position through the first rack section 160a and the second rack section 151a, which simplifies the realization of the wind guide. The driving design of the translation and rotation of the plate 150 makes the entire driving design compact and exquisite, which facilitates the translation of the air deflector 150 in the indoor unit 100 with a small space, and ensures that the air deflector 150 is in the second position. The stable rotation.

[0115] Furthermore, in the wall-mounted air conditioner indoor unit 100 of this embodiment, the upper plate section 151 is formed with a first air dissipating hole 151d, and the lower plate section 152 is formed with a second air dissipating hole 152b, and the airflow can pass through the upper plate section 151. The first air dissipating hole 151d of the lower plate section 152 and the second air dissipating hole 152b of the lower plate section 152 are blown out to form a breeze airflow, which makes the temperature of the supply air flow suitable, and prevents the high wind speed of the cold wind during cooling and the problem of poor blowing experience on people, making users The body feels more comfortable.
