As shown in fig. 1, when the air conditioner indoor unit 100 stops operating, the opening and closing door 13 may be reversely moved with respect to the opening and closing door mounting plate 12 to close the first air outlet 11a, thereby sealing the air conditioner indoor unit 100.

Alternatively, the opening and closing door 13 may be moved up and down with respect to the opening and closing door mounting plate 12 to open or close the first air outlet 11a. For example, when the indoor unit 100 of the air conditioner starts to operate, the opening and closing door 13 may be moved upward with respect to the opening and closing door mounting plate 12 to open the first air outlet 11a. When the air conditioner indoor unit 100 stops operating, the switch door 13 may move downward with respect to the switch door mounting plate 12 to close the first air outlet 11a.

As shown in fig. 3, a sealing member 14 may be provided on a rear sidewall of the front panel 11, and a vent 14a communicating with the first air outlet 11a may be provided on the sealing member 14, and when the opening and closing door 13 closes the first air outlet 11a, the sealing member 14 may be positioned between the opening and closing door 13 and the front panel 11 to seal a gap between the opening and closing door 13 and the front panel 11. It will be appreciated that the front panel 11 is typically an injection molded part and that the front panel 11 is highly susceptible to deformation during injection molding and transportation. When the front panel 11 is engaged with the opening and closing door 13, there is an assembly gap between the front panel 11 and the opening and closing door 13. The sealing member 14 can seal the assembly gap between the switch door 13 and the front panel 11, thereby improving the fit tightness between the switch door 13 and the front panel 11, and preventing dust and impurities in the air from entering the gap between the switch door 13 and the front panel 11 through the first air outlet 11a, so as to protect the air conditioner indoor unit 100 and enable the air conditioner indoor unit 100 to operate normally. In addition, a plurality of parts can be arranged on the rear side wall of the front panel 11, and the sealing element 14 is arranged between the switch door 13 and the front panel 11, so that the switch door 13 can be prevented from being scratched by the parts on the rear side wall of the front panel 11 when moving, and the switch door 13 can keep good appearance attractiveness.

According to the panel component 1 of the air conditioning indoor unit 100 of the embodiment of the invention, the sealing element 14 is arranged between the switch door 13 and the front panel 11, and the sealing element 14 can seal the assembly gap between the switch door 13 and the front panel 11, so that the matching tightness between the switch door 13 and the front panel 11 can be improved, dust and impurities in air can be prevented from entering the air conditioning indoor unit 100, and the normal operation of the air conditioning indoor unit 100 can be ensured. Moreover, the sealing member 14 can prevent the switch door 13 from being scratched by parts on the rear side wall of the front panel 11 when moving, so that the switch door 13 can maintain good appearance and beautiful appearance. Meanwhile, when the switch door 13 opens the first air outlet 11a, the sealing member 14 can prevent air flow from leaking from a gap between the switch door 13 and the front panel 11, and prevent air loss.

According to some embodiments of the present invention, the sealing member 14 may be snap-fitted with the front panel 11, thereby making the fitting manner of the sealing member 14 with the front panel 11 simpler and facilitating the installation and replacement of the sealing member 14.

For example, the sealing member 14 may be connected to the front panel 11 by screw connection or riveting, and the sealing member 14 may be fixed to the front panel 11 by adhesive bonding.

As shown in fig. 3 and 11, in some embodiments of the present invention, a catch 111 may be provided on a rear sidewall of the front panel 11, a catch 141 may be provided on the sealing member 14, and the catch 111 may be inserted into the catch 141. Of course, the back side wall of the front panel 11 may be provided with a locking groove 141, and the sealing member 14 may be provided with a locking hook 111. Thus, by the above arrangement, the connection between the front panel 11 and the seal member 14 can be made simpler and the assembly can be facilitated. Further, the number of the hooks 111 and the slots 141 may be plural, and the hooks 111 and the slots 141 are in one-to-one correspondence and inserted into the corresponding slots 141, so that the connection structure between the sealing member 14 and the front panel 11 is more firm.

As shown in fig. 3, in some embodiments of the present invention, the hooks 111 may be a plurality of hooks disposed at intervals from top to bottom, and the top wall and the bottom wall of the sealing element 14 may be provided with a slot 141, and each hook 111 may be in snap fit with the corresponding slot 141, so that the connection between the sealing element 14 and the front panel 11 may be more firm.

For example, the hooks 111 may be formed in two rows spaced apart in the up-down direction, each row including three spaced apart hooks 111, and three spaced apart slots 141 are provided in the top and bottom walls of the sealing member 14. When the sealing member 14 is assembled with the front panel 11, the sealing member 14 may be first moved up and down so that the catch 111 located above is inserted into the corresponding catch groove 141 on the top wall of the sealing member 14, and then the lower side of the sealing member 14 is pushed from the rear to the front so that the catch 111 located below is inserted into the corresponding catch groove 141 on the bottom wall of the sealing member 14. Thus, by the above arrangement, the fitting manner of the seal 14 and the front panel 11 can be made simpler and more labor-saving.

As shown in fig. 3, in some specific examples of the present invention, the plurality of hooks 111 include first hooks 111a and second hooks 111b that are spaced apart in the up-down direction and are arranged in rows, a top wall of the sealing member 14 is provided with first clamping grooves 141a that are in one-to-one correspondence with the plurality of first hooks 111a, and a bottom wall of the sealing member 14 is provided with second clamping grooves 141b that are in one-to-one correspondence with the plurality of second hooks 111 b.

Wherein, as shown in fig. 4, each first hook 111a includes a first horizontal extension arm 1111 and a first vertical extension arm 1112, one end of the first horizontal extension arm 1111 is connected to the front panel 11, the other end of the first horizontal extension arm 1111 extends backward and is connected to the first vertical extension arm 1112, and one end of the first vertical extension arm 1112 remote from the first vertical extension arm 1112 extends downward. A first guide slope 1113 is provided on the front side wall of the first vertically extending arm 1112, and the first guide slope 1113 extends obliquely in a direction away from the front panel 11 in a top-down direction. At least one reinforcing plate 1114 is further provided between the first horizontal extension arm 1111 and the front panel 11, the reinforcing plate 1114 is formed in a triangular prism shape, and two mutually perpendicular sides of the reinforcing plate 1114 are respectively connected to the front panel 11 and the first horizontal extension arm 1111.

As shown in fig. 5, each second hook 111b includes a second horizontal extension arm 1115 and a locking protrusion 1116, and both ends of the second horizontal extension arm 1115 are respectively connected to the front panel 11 and the locking protrusion 1116, and the locking protrusion 1116 extends upward with respect to the second horizontal extension arm 1115. Wherein, the side wall of the locking protrusion 1116 far from the front panel 11 is provided with a second guiding inclined plane 1116a, and the second guiding inclined plane 1116a extends obliquely towards the direction close to the front panel 11 in the direction from bottom to top.

When the sealing member 14 is assembled with the front panel 11, the sealing member 14 may be first moved up and down, as shown in fig. 12, each of the first hooks 111a may be inserted into the corresponding first catching groove 141a by the guide of the first guide slope 1113, as shown in fig. 13, and then the lower side of the sealing member 14 may be pushed from the rear to the front so that each of the catching protrusions 1116 may be hooked on the rear sidewall of the sealing member 14 in the corresponding second catching groove 141b into which each of the second hooks 111b is inserted by the guide of the second guide slope 1116 a. Thus, by the above arrangement, the plurality of first hooks 111a and the plurality of first clamping grooves 141a are snap-fitted, and the plurality of second hooks 111b and the plurality of second clamping grooves 141b are snap-fitted, so that the seal 14 can be firmly fixed to the front panel 11.

As shown in fig. 11 and 14, according to some embodiments of the present invention, the outer circumferential edge of the first air outlet 11a may be provided with a socket protrusion 112, and the sealing member 14 may be provided with a socket hole 142 corresponding to the socket protrusion 112, and the socket protrusion 112 may be inserted into the corresponding socket hole 142. It can be appreciated that, since the first air outlet 11a is disposed on the front panel 11, the peripheral edge portion of the first air outlet 11a is very prone to warping and deformation, and the mating of the plugging protrusion 112 and the plugging hole 142 can make the mating of the sealing member 14 and the front panel 11 tighter, so that the structural tightness of the panel component 1 can be improved.

In some embodiments of the present invention, the insertion protrusions 112 may be plural, the plural insertion protrusions 112 may be spaced apart in the circumferential direction of the first air outlet 11a, the insertion holes 142 may be plural, and the plural insertion holes 142 may be provided along the outer circumference of the air vent 14a and spaced apart in the circumferential direction of the air vent 14 a. Therefore, the first air outlet 11a and the air vent 14a can be arranged opposite to each other, and the sealing member 14 can be tightly attached to the rear side wall of the front panel 11 through the cooperation of the plurality of inserting protrusions 112 and the plurality of inserting holes 142, so that the overall structure of the panel component 1 can be more compact, and the structural compactness of the panel component 1 can be further improved.

Alternatively, as shown in fig. 7, a third guide slope 112a may be provided on a side wall of at least one of the insertion projections 112, and the third guide slope 112a may extend obliquely toward a center position near the first air outlet 11a in a front-to-rear direction. Thus, with the above arrangement, the third guide slope 112a can function as a guide, and the engagement of the plug projection 112 and the plug hole 142 can be made smoother.

As shown in fig. 10-11, according to some embodiments of the present invention, one of the sealing member 14 and the front panel 11 may be provided with a positioning hole 143, and the other of the sealing member 14 and the front panel 11 may be provided with a positioning member 113 protruding into the positioning hole 143. That is, the positioning member 113 may be provided on the sealing member 14, the positioning hole 143 may be provided on the front panel 11, or the positioning hole 143 may be provided on the sealing member 14, and the positioning member 113 may be provided on the front panel 11. Thus, by the above arrangement, the positioning member 113 cooperates with the positioning hole 143 to perform a predetermined positioning function for the sealing member 14, so that the assembling efficiency of the positioning member 113 and the front panel 11 can be improved.

As shown in fig. 6 and 15, in some specific examples of the present invention, the positioning member 113 may include a first extension portion 113a extending horizontally and a second extension portion 113b extending vertically, both ends of the first extension portion 113a being connected to the front panel 11 and the second extension portion 113b, respectively. When the sealing member 14 is engaged with the front panel 11, the first extension 113a may be stopped against the inner peripheral wall of the positioning hole 143, and the second extension 113b may be hooked on the sealing member 14. Thus, by the above arrangement, the positioning member 113 not only can play a role of the predetermined positioning, but also can make the fitting of the sealing member 14 with the front panel 11 more firm.

According to some embodiments of the present invention, at least a portion of the sealing member 14 located above the ventilation opening 14a may be provided with a brush that is in contact with the openable door 13. Specifically, the brush may be provided on a side wall (a rear side wall as shown in fig. 9) of the sealing member 14 away from the front panel 11, may be provided only at a portion of the rear side wall of the sealing member 14 above the ventilation opening 14a, or may be provided at all portions of the rear side wall of the sealing member 14 away from the ventilation opening 14 a. Wherein, the brush not only can be in sealing contact with the switch door 13 to prevent dust from entering the indoor unit 100, but also can clean foreign matters (such as dust) on the outer surface of the switch door 13 when the switch door 13 moves relative to the front panel 11, thereby keeping the appearance of the switch door 13 clean.

In some specific examples of the present invention, a portion of the rear sidewall of the sealing member 14 above the ventilation opening 14a is provided with a brush, and the opening and closing door 13 may be moved up and down with respect to the front panel 11 to open or close the first air outlet 11a. When the switch door 13 closes the first air outlet 11a, the switch door 13 moves from top to bottom and gradually closes the first air outlet 11a. In the process of closing the first air outlet 11a by the opening and closing door 13, the brush first contacts the bottom of the opening and closing door 13 and sweeps the front surface of the opening and closing door 13 downward and upward. When the switch door 13 completely closes the first air outlet 11a, the brush is positioned above the first air outlet 11a and is in sealing fit with the switch door 13, so that dust in the air can be prevented from entering the air conditioning indoor unit 100 through the gap between the switch door 13 and the first air outlet 11a. When the opening and closing door 13 opens the first air outlet 11a, the opening and closing door 13 moves from bottom to top and gradually opens the first air outlet 11a. In the process of opening the first air outlet 11a by opening and closing the door 13, the brush cleans the front surface of the door 13 upward and downward. When the opening and closing door 13 fully opens the first air outlet 11a, the brush may be positioned under the opening and closing door 13.

It will be understood, of course, that when the opening and closing door 13 fully opens the first air outlet 11a, the brush may also be kept in contact with the lower portion of the opening and closing door 13, and may be selectively set according to the size of the actual assembly space and the use requirement, which is not particularly limited in the present invention.

According to some embodiments of the present invention, the outer periphery of the sealing member 14 may be provided with a protrusion 144 extending toward the front panel 11, the protrusion 144 may abut against the rear sidewall of the front panel 11, the protrusion 144 may not only reinforce the sealing member 14, but the protrusion 144 may also facilitate the assembly of the sealing member 14 with the front panel 11. Alternatively, as shown in fig. 10, the boss 144 may extend in the circumferential direction of the seal member 14 to form a closed loop, whereby the fitting structure of the seal member 14 with the front panel 11 may be made tighter.

According to some embodiments of the present invention, the panel part 1 may further include a driving mechanism 15, and the driving mechanism 15 may be connected to the opening and closing door 13 to drive the opening and closing door 13 to move, so that automatic control of the opening and closing door 13 may be achieved, and use of the air conditioning indoor unit 100 may be facilitated. For example, the driving mechanism 15 may be in communication with an air conditioner remote controller, and the air conditioner remote controller may be operated to control the working state of the driving mechanism 15, so as to achieve the purpose of automatically opening or closing the first air outlet 11 a.

As shown in fig. 17, in some embodiments of the present invention, the driving mechanism 15 may include a driving member (not shown), a driving gear 151 and a rack 152, where the driving member may be disposed on the door mounting plate 12, the driving gear 151 may be connected to the driving member to be driven to rotate by the driving member, the rack 152 may be connected to the door 13, and the rack 152 may be engaged with the driving gear 151 to move the door 13. Thus, by the above arrangement, the structural design of the driving mechanism 15 can be made simpler. Moreover, the operation of the rack and pinion mechanism is more stable, and the operational stability of the switch door 13 can be improved.

Alternatively, the driving member may be a stepping motor, and the stepping motor has the characteristics of stable operation and precise control of the rotation angle and rotation number thereof, so that the movement displacement of the opening and closing door 13 can be precisely controlled by controlling the rotation number of the driving member, and the opening and closing door 13 can be completely opened or completely closed to the first air outlet 11a.

In the specific example shown in fig. 17, the driving gear 151 may further include a driving gear 151a and a driven gear 151b, wherein the driving gear 151a may be connected to the driving member to be driven to rotate by the driving member, the driven gear 151b may be engaged with the driving gear 151a and the rack 152 at the same time, the driven gear 151b may function to transmit power, and thus, the driving gear 151a and the driven gear 151b may cooperate with each other to function to adjust the operation speed of the rack 152 and may also improve the operation stability of the rack 152.

As shown in fig. 1 to 2, an air conditioning indoor unit 100 according to an embodiment of the present invention includes a panel member 1 of the air conditioning indoor unit 100 according to the above-described embodiment of the present invention.

In some embodiments of the present invention, the indoor unit 100 of an air conditioner may include a panel part 1 and a back panel part 2, the panel part 1 is disposed on a front side of the back panel part 2 and connected to the back panel part 2, a first air outlet 11a and a second air outlet 11b may be disposed on the panel part 1, and an air inlet may be disposed on the back panel part 2. The indoor unit 100 of the air conditioner may further include an air duct component, where the air duct component is disposed in an installation space defined by the panel component 1 and the back board component 2, and a first fan component and a second fan component are disposed on the air duct component, where the first fan component is opposite to the first air outlet 11a, and the second fan component is opposite to the second air outlet 11 b.

The first wind wheel component is a disrotatory fan, and the second fan component is an axial flow fan. The first fan assembly comprises a first wind wheel and a second wind wheel which are opposite to each other in the front-back direction, the inclination direction of the blades of the first wind wheel is opposite to the inclination direction of the blades of the second wind wheel, the first wind wheel and the second wind wheel are guide vanes mutually in the air flow direction, so that the tangential rotation speed of air flow (namely dynamic pressure is converted into static pressure under the condition that the first wind wheel and the second wind wheel are at the same rotation speed) can be reduced or eliminated (under the condition that the first wind wheel and the second wind wheel are at different rotation speeds), the acting efficiency of the counter-rotating fan on air is improved, and the air flow passing through the two wind wheels flows towards the direction of an air outlet, thereby realizing the effect of remote air supply. It should be noted that, compared with a single cross flow fan, an axial flow fan or an oblique flow fan, the first wind wheel and the second wind wheel in the counter-rotating fan can realize the air supply of a longer distance regardless of the reverse rotation at different speeds or the reverse rotation at the same speed.

Moreover, the first wind wheel and the second wind wheel can expand the cold air conveying range under the condition of different rotating speeds. Because when one wind wheel rotates at a higher rotating speed and the other wind wheel rotates at a lower rotating speed, the wind wheel with the higher rotating speed plays a leading role, and the blade air outlet angle design based on the single-stage axial flow or diagonal flow fan deviates from the direction of the rotating shaft, the axial flow wind wheel or diagonal flow wind wheel has a wind dispersing effect, so that the angle range of cold air flowing out from the first air outlet 11a is larger, and wide-angle air supply is realized. In addition, based on the wind dispersing effect of the axial flow wind wheel or the diagonal flow wind wheel, the rotating speeds of the first wind wheel and the second wind wheel can be adjusted according to the requirement, so that the differential rotation of the first wind wheel and the second wind wheel is realized, soft wind sense or wind sense-free air supply is realized, and bad experience caused by direct blowing of cold air after the cold air flows out from the first air outlet 11a to a user is avoided. Therefore, the air conditioning indoor unit 100 according to the embodiment of the invention can realize soft air feeling or air supply without air feeling without using an air deflector with micropores, and has less air loss. In order to realize wide-angle air supply and air supply without wind sense, the motor corresponding to one wind wheel does not work, and the other wind wheel still supplies air towards one side of the air outlet. In addition, in order to realize wide-angle air supply and air supply without wind sense, one wind wheel can also reversely supply air to the inner side of the shell, and the other wind wheel can still supply air positively. The positive air supply is that the air flow is blown out from the air outlet under the action of the wind wheel, and the negative air supply is that the air flow is blown into the inner side of the shell.

According to the air conditioning indoor unit 100 of the embodiment of the present invention, by providing the panel member 1, the sealing member 14 in the panel member 1 can improve the structural compactness of the air conditioning indoor unit 100, and can ensure smooth operation of the air conditioning indoor unit 100.
