The invention provides a floor type air conditioner indoor unit.
in the embodiment of the present invention, as shown in fig. 1 to 12, the floor type air conditioning indoor unit includes a casing 100, a top air outlet frame 200, a switch door 300, and a fan assembly (not shown). The housing 100 has an inlet 110, the housing 100 is provided with an installation opening 120 with an upward opening, and an air duct 130 is formed between the inlet 110 and the installation opening 120. The top air-out frame 200 is installed at the installation opening 120 in a way of moving up and down, and the lower end and the front end of the top air-out frame 200 are open. The switch door 300 is installed on the housing 100 or the top air-out frame 200, and the switch door 300 has a closed state for blocking the airflow in the air duct 130 from blowing to the lower port 210 of the top air-out frame 200, and an open state for communicating the air duct 130 and the lower port 210. A fan assembly (not shown) is installed in the air duct 130, and when the opening/closing door 300 is in an open state, the fan assembly (not shown) is used for blowing an air flow from the air inlet 110 to the lower port 210 and from the front port 220 of the top air-out frame 200.
In the present embodiment, it is understood that the overall shape of the housing 100 can be selected and set according to the use requirement and design requirement. The floor type air conditioner indoor unit is generally arranged in a vertically extending manner. The cross section of the casing 100 may be circular, oval, rectangular, irregular, etc., and is not limited in this respect. The cross-sectional shape of the top air-out frame 200 may be various, such as circular, oval, rectangular, irregular, etc. The shape of the intake vent 110 may be circular, rectangular, oval, irregular, etc., and may also be a plurality of micro-holes. The air inlet 110 can be an indoor air inlet 110 and/or a fresh air inlet 110. The size of the mounting opening 120 is set to allow the top air frame 200 to pass through. In order to improve the air leakage preventing effect and the moving effect of the top air-out frame 200, the shape and size of the installation opening 120 may be adapted to the shape and size of the top plate of the top air-out frame 200. The mounting port 120 may be disposed on the top plate of the housing 100, or may be disposed at another position, so that the opening of the mounting port 120 is upward only, and the top air frame 200 can move up and down. A heat exchanger may be disposed in the air duct 130 to blow out cold air or hot air after heat exchange.
the top air-out frame 200 can be installed on the housing 100, or can be installed on other structures inside the housing 100, only by installing the top air-out frame 200 at the installation opening 120 correspondingly. The top air-out frame 200 can be moved up and down in a manual adjustment mode, and the top air-out frame 200 can also be driven to move up and down by the driving device 400. The top air outlet frame 200 can slide up and down through a groove rail structure, and can also move up and down through a screw adjusting structure, a screw rod structure, a gear rack structure and the like. It is understood that the top air outlet frame 200 has a thin-walled cavity structure. It should be noted that the front end of the top air outlet frame 200 means that, after the floor type air conditioner indoor unit is installed in place, the end facing the user is the front end. The lower port 210 refers to an opening at the lower end of the top outlet frame 200, and the front port 220 refers to an opening at the front end of the top outlet frame 200. By making the lower end and the front end of the top air-out frame 200 be open, the airflow flows into the cavity of the top air-out frame 200 from the lower port 210 of the top air-out frame 200 and can flow out from the front port 220.
The opening and closing door 300 may be installed in the housing 100 or in the top air-out frame 200. When the switch door 300 is installed in the housing 100, it can block or open the air duct 130 to block the air flow in the air duct 130 from blowing toward the lower port 210 or to connect the air duct 130 and the lower port 210. The switch door 300 may also switch between the open state and the closed state by opening or closing the lower port 210. When the opening and closing door 300 is installed in the top air-out frame 200, the opening and closing door 300 can be switched to an opened or closed state by opening or closing the lower port 210. The opening and closing door 300 may be switched between an opened state and a closed state by means of translation, contraction, folding, or rotation, and is not particularly limited herein. The opening and closing door 300 may be of a whole door panel structure or a louver structure, and only needs to be capable of switching between a closed state and an open state. When the switch door 300 is in the closed state, the switch door 300 can block the airflow in the air duct 130 from blowing toward the lower port 210 of the top air-out frame 200, thereby preventing the airflow from blowing toward the top air-out frame 200. So, the air inlet end from top air-out frame 200 blocks that the air current passes through, then compares in the air-out end of shutoff top air-out frame 200, can avoid the air current to scurry into top air-out frame 200 in, reduces the air current circulation route, reduces the unnecessary air current and flows. It can be understood that the switch door 300 can completely block the airflow in the air duct 130 from blowing towards the lower port 210 of the top air-out frame 200. When the switch door 300 is in the open state, the air in the air duct 130 can smoothly flow into the lower port 210 of the top air-out frame 200, and further flow out from the front port 220.
The casing 100 may be a single-layer shell-shaped structure, the air duct 130 is formed only in the single-layer casing 100, the mounting opening 120 with the upward opening is disposed on the single-layer casing 100, and at this time, the top air outlet frame 200 may extend out of the casing 100. The top air-out frame 200 can be set to extend out of the casing 100, that is, the top air-out frame 200 can be set to extend out of the casing 100 in the up-and-down moving process. Therefore, the front port 220 of the top air-out frame 200 is always communicated with the indoor space, and the air-out height and the air-out range of the top air-out frame 200 can be adjusted by moving the top air-out frame 200 up and down. It is also possible to have the top air-out frame 200 have a position moved to protrude out of the housing 100 and a position moved to be accommodated under the mounting opening 120. Thus, when top air outlet is needed, the top air outlet frame 200 is moved to a position extending out of the casing 100, so that air flow can be blown out from the front port 220. When the top air-out mode is not needed, the top air-out frame 200 can be moved to a position where the top air-out frame is accommodated below the mounting opening 120, and then the casing 100 blocks the front port 220 of the top air-out frame 200, so that the air flow is not blown out from the front port 220. So for the air supply mode is more diversified, simultaneously when need not using the top air-out mode, can descend the top air-out frame 200 to the casing 100 in, and then reduces the height of complete machine, makes the occupation space of complete machine little.
In one embodiment, as shown in fig. 2 to 7, the casing 100 includes a casing (not shown) and an air duct casing 150 installed inside the casing (not shown), the mounting opening 120 is located on a top surface of the air duct casing 150, an air duct 130 is formed inside the air duct casing 150, and the top air outlet frame 200 is installed on the air duct casing 150 to be movable up and down. Specifically, the switch door 300 is mounted to the air duct case 150 or the top air-out frame 200. The intake vent 110 may be disposed on the air duct housing 150, or may be disposed on a housing (not shown). The air entering the air duct 130 may be heat exchange air, indoor air, fresh air, or other purified air flow. A heat exchanger or the like may be provided in the air duct 130. It will be appreciated that the housing (not labeled) conforms to the shape of the air duct shell 150. The air duct shell 150 may be integrally formed, or may be formed by splicing two sub-shells. A sufficient moving space may be left between the top plate of the housing (not shown) and the top plate of the air duct shell 150, or may be attached to the housing, or a small gap may be formed between the top plate and the air duct shell. Then, under the condition that there is a sufficient space between the top plate of the housing (not shown) and the top plate of the air duct casing 150, the top air outlet frame 200 can move up and down in the housing (not shown), at this time, the air outlet 141 can be opened on the front side of the housing (not shown) between the top plate of the housing (not shown) and the top plate of the air duct casing 150, and the air outlet height of the front port 220 can be adjusted by adjusting the up-and-down movement position of the top air outlet frame 200.
of course, an extending opening may be formed on the top plate of the housing (not shown) corresponding to the mounting opening 120 of the air duct casing 150, so as to extend the top air outlet frame 200. Thus, the airflow can be directly blown into the room from the front port 220 of the top air frame 200, and the height of the housing (not shown) is reduced, so that the volume of the whole machine is smaller. At this moment, the top air-out frame 200 can be extended out of the housing (not marked) all the time, and the height of air-out can be adjusted by adjusting the extension height of the top air-out frame 200, so that the air supply range is enlarged, and different air supply requirements of users are met.
In an embodiment, referring to fig. 1 to 6, 11 and 12, the top air-out frame 200 has a first position extending out of the mounting opening 120 and a second position received in the air duct housing 150, when the top air-out frame 200 is located at the first position, the opening/closing door 300 is in an open state, and when the top air-out frame 200 is located at the second position, the opening/closing door 300 is in a closed state. Thus, when the top air outlet mode is not needed, the top air outlet frame 200 can be stored and hidden in the air duct shell 150. Thereby reducing the height of the whole machine and reducing the occupied space of the whole machine.
it will be appreciated that in order to increase the air output, a conventional air outlet 141 is typically provided at the front side of the housing (not shown) and communicates with the air duct 130. In the normal mode, air is discharged through the normal air outlet 141, and the top air outlet frame 200 does not discharge air. In the top air outlet mode, the regular air outlet 141 and the top air outlet frame 200 are simultaneously exhausted. When top air-out frame 200 is in the second position of accomodating to wind channel shell 150, because top air-out frame 200 is the cavity structure, if there is not switch door 300 structure for the air current can be blown to in the top air-out frame 200, and then can form the noise, influences user experience. Meanwhile, in the conventional air outlet mode, since the airflow flows into the top air outlet frame 200 and then returns to the air duct 130 to flow out of the conventional air outlet 141, the flow path of the airflow is increased, and a vortex is easily formed in the top air outlet frame 200, thereby causing air loss. When the top air-out frame 200 is at the second position of being accommodated in the air duct casing 150, the switch door 300 is in the closed state. The air flow blown out from the conventional outlet 141 is not blown toward the top outlet frame 200, so that noise is greatly reduced or avoided, and air loss can be effectively prevented. Meanwhile, if there is no structure for sealing the door 300, the air leakage phenomenon occurs in the top air-out frame 200, and the air flow cooled by the heat exchanger flows into the low-pressure region through the gap between the top air-out frame 200, so that the condensation phenomenon occurs in the top air-out frame 200. Through setting up switch door 300, the separation air current gets into to the top in the air-out frame 200, can also effectually avoid a top air-out frame 200 to produce the condensation phenomenon.
The fan assembly (not shown) may include only one fan, which may be an axial fan, a centrifugal fan, or a cross-flow fan. The opening position of the air inlet 110 may be adjusted according to the type of the fan used, and is not limited herein. The wind wheel and the motor can be included, the motor drives the wind wheel to rotate, when the switch door 300 is in an open state, enough airflow is driven to enter the air duct 130 from the air inlet 110, then the airflow is blown to the lower port 210 of the top air-out frame 200, enters the cavity of the top air-out frame 200, and then is blown out from the front port 220 of the top air-out frame 200.
In the floor type air conditioner indoor unit of the present invention, the mounting opening 120 with an upward opening is formed in the casing 100, so that the top air-out frame 200 can be vertically moved and mounted at the mounting opening 120, the lower end and the front end of the top air-out frame 200 are open, and the fan assembly (not shown) is configured to blow an air flow from the air inlet 110 to the lower port 210 of the top air-out frame 200 and out from the front port 220 of the top air-out frame 200. The floor type air conditioner indoor unit has a top air outlet mode, and the top air outlet frame 200 can move up and down, so that the air outlet height of the front port 220 of the top air outlet frame 200 can be conveniently adjusted, or the top air outlet frame 200 can be lowered into the shell 100 when not needed. Therefore, the air supply form of the floor type air conditioner indoor unit is various, and the air supply range is wider.
Meanwhile, the switch door 300 is disposed on the housing 100 or the top air-out frame 200, so that the switch door 300 has a closed state for blocking the air flow in the air duct 130 from blowing to the lower port 210 of the top air-out frame 200, and an open state for communicating the air duct 130 with the lower port 210. Thus, by switching the open state and the closed state of the switch door 300, it is possible to control whether the airflow in the air duct 130 enters the top air-out frame 200 through the lower port 210. Therefore, when the air does not need to be discharged from the top air outlet frame 200, the air flow in the air channel 130 can be separated by opening and closing the door 300 to blow towards the lower port 210 of the top air outlet frame 200, so that the air channeling in the top air outlet frame 200 can be prevented, and the air volume loss is avoided.
