The air guide plate 130 is disposed at the air outlet 120 and is used for opening and closing the air outlet 120. The air conditioner may generally employ an existing compression refrigeration system, and will not be described in detail herein. The baffle 102 is configured to be coupled to the housing 101 via a drive mechanism and moved relative to the housing 101 by the drive mechanism such that the baffle 102 has at least a first state closing the inlet 110 and a second state directing air flowing out of the housing 101 at the outlet 120. The air conditioner indoor unit 100 of the embodiment of the invention is provided with the baffle plate 102, and the baffle plate 102 is arranged to be connected with the shell 101 through the driving mechanism and move relative to the shell 101 under the action of the driving mechanism, so that the baffle plate 102 at least has a first state of sealing the air inlet 110 and a second state of conducting drainage on air flowing out of the shell 101 at the air outlet 120, the air inlet 110 is sealed by utilizing the baffle plate 102 when the air conditioner is not used, dust falling of the air inlet 110 is avoided, meanwhile, the air outlet of the air outlet 120 can be conducted through drainage by utilizing the baffle plate 102 when the air conditioner is in operation, direct blowing is avoided, and the blowing feeling of a user is.
The casing 101 may be provided with a baffle slot (not shown) at the air inlet 110 of the top wall 112 thereof, so that when the baffle 102 is in the first state, the upper surface of the baffle 102 is flush with the upper surface of the top wall 112 of the casing 101, thereby improving the aesthetic appearance of the indoor unit 100.
Fig. 2 shows a structure of a part of components inside the casing 101 of the indoor unit 100 with the front panel 111 removed. In some embodiments, the drive mechanism includes a rocker 103, a cam 104, an assist lever 105, a lift motor 106, and a rotation motor 107. The left side wall 113 and/or the right side wall 114 of the housing 101 are opened with a slide groove 140 in the up-down direction. The rocker 103 is arranged outside the chute 140, and the baffle 102 is transversely arranged at the upper part. The lifting motor 106 is fixed in the housing 101, and the output shaft is connected with the cam 104. The auxiliary rod 105 is disposed above the cam 104, and the end of the auxiliary rod passes through the sliding groove 140 and then is fixed to the rocker 103, so that the cam 104 rotates to contact with the bottom surface of the auxiliary rod 105 by controlling the operation of the lifting motor 106, the auxiliary rod 105 is lifted, and the baffle 102 is lifted. The lift motor 106 may be a stepper motor. As shown in fig. 2, a fixing plate 160 is provided in the housing 101, the lift motor 106 is fixed to one side of the fixing plate 160 by a fixing member, such as a screw, and the cam 104 is provided at the end of the output shaft.

In some embodiments, the second portion 142 of the cam 104 transitions smoothly from the first portion 141, and the width of the second portion 142 is less than the width of the first portion 141. Due to repeated friction between the cam 104 and the auxiliary rod 105 during the lifting process, the second part 142 is arranged to be in smooth transition with the first part 141, so that the cam 104 has a smooth upper surface, and the abrasion is reduced.
The driving parts of the indoor unit 100 are preferably designed to be symmetrical to each other, so that the movement of the barrier 102 up and down and the rotation thereof can be more stable, and the manufacturing cost of the parts can be reduced. In some embodiments, the number of the sliding grooves 140 is two, and the sliding grooves are symmetrically formed on the left side wall 113 and the right side wall 114 of the housing 101; the number of the rockers 103 is two, and the number of the rotating motors 107 is two; the number of the cams 104 is two, the number of the lifting motors 106 is two, and the second parts 142 of the two cams 104 are oppositely arranged; the auxiliary rod 105 is disposed above the two cams 104 in the left-right direction, and the left and right ends thereof respectively pass through the sliding groove 140 and are fixed to the rocking bar 103. At this time, when the indoor unit 100 is operated, the lift motors 106 of the two cams 104 rotate in one forward direction and one reverse direction, so that both the cams 104 rotate upward and contact the auxiliary lever 105.
As shown in fig. 2, the indoor unit 100 further includes guide rails 150 disposed on both sides of the lower portion of the sliding groove 140 on the left side wall 113 and/or the right side wall 114 of the casing 101, so that the lower portion of the rocker 103 is located in the guide rails 150 when the barrier 102 is in the first state. The length of the rocker handle mounted in the guide rail 150 is equal to the length of the cam 104. By providing the guide rail 150, the stability of the rocker 103 in lifting can be improved.
In some embodiments, the baffle 102 of the indoor unit 100 of the present invention is configured to: and has a third state away from the intake vent 110 and the outtake vent 120. That is, the baffle 102 neither seals the inlet 110 nor guides the outlet air of the outlet 120, as shown in fig. 6, at this time, the outlet air of the indoor unit 100 is directly blown.
In some embodiments, the second state of the baffle 102 of the indoor unit 100 according to the embodiment of the present invention includes a stationary state in which the baffle 102 is stationary at the outlet 120, and an active state in which the baffle 102 is reciprocally swung in the front-rear direction at the outlet 120. That is, when the baffle 102 guides the air flowing out of the air outlet 120, the air can be guided in a fixed angle and a fixed position, or the air can be guided movably by swinging back and forth. When the baffle plate 102 is in the active state, the air outlet at the periphery can be disturbed again, so that the air outlet temperature is more uniform, the comfort level of a user is improved, and the air conditioner is particularly suitable for an air conditioner in a refrigeration mode, and the cold air direct blowing user is avoided.
In some embodiments, the indoor unit 100 is configured to: when the difference between the ambient temperature of the surrounding environment where the indoor unit 100 is located and the coil temperature of the indoor unit 100 is greater than the preset temperature threshold, the baffle 102 is in the active state. By configuring the indoor unit 100 such that the baffle 102 is in the active state when the difference between the ambient temperature and the coil temperature of the indoor unit 100 is greater than the preset temperature threshold, the outlet air temperature can be more uniform, and the air blowing feeling of the user can be improved.
In some embodiments, the indoor unit 100 is configured to: when the indoor unit 100 receives the blow-through prevention control command, the shutter 102 is set to the active state. The indoor unit 100 further includes a receiving device for receiving the blow-through prevention control command. For example, a remote controller corresponding to the air conditioner is provided with a blow-through prevention key for triggering a blow-through prevention control instruction, a user triggers the blow-through prevention control instruction by pressing or clicking the blow-through prevention key, when the blow-through prevention control instruction triggered by the blow-through prevention key is detected, a control end such as the remote controller sends the blow-through prevention control instruction to a receiving device, and after the receiving device receives the blow-through prevention control instruction, the control baffle 102 is in an active state.
The operation of the driving mechanism will be briefly described below. When the air conditioner is not turned on, the baffle 102 is in the first state and is positioned in the baffle slot to close the air inlet 110, as shown in fig. 1 and 3.
